Answer:

I would say 109 it looks a bit bigger than a 90-degree angle.

Step-by-step explanation:

if we take the line which is 180 and subtract 127 we get 53 from it.

We use 360  as another number considering the other angle is bigger than 180 so we do 360-304=56

So adding both together we get that x should be 109

Hope this helped.

Answer:

Option A $468.00

Step-by-step explanation:

To calculate the total price of the first invoice that activates the chain discount, we need to first calculate the net price per item after the chain discount is applied.

The chain discount is 30/25, which means that we get two discounts. First, a 30% discount on the list price, and then an additional 25% discount on the resulting price. We can calculate this as follows:

Discount 1 = 30% x $80 = $24

Price after Discount 1 = $80 - $24 = $56

Discount 2 = 25% x $56 = $14

Price after Discount 2 = $56 - $14 = $42

So the net price per item after the chain discount is $42.

To activate the chain discount, the invoice subtotal must be above $1,000. Let's assume that we order x items. Then the invoice subtotal is:

Invoice Subtotal = $42 x (number of items)

We want to find the value of x that makes the invoice subtotal just above $1,000. In other words:

$42 x (number of items) > $1,000

Dividing both sides by $42, we get:

(number of items) > $1,000 / $42

(number of items) > 23.81

We can't order a fraction of an item, so we need to round up to the next whole number. This gives us:

(number of items) = 24

So we need to order at least 24 items to activate the chain discount. The total price of the first invoice that activates the chain discount is:

Total Price = $42 x 24 = $1,008

Therefore, the answer is option A. $468.00.

The total price of the first invoice that activates the chain discount is $546.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Percent simplified means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Now, to get the discount he must buy at least.

\(\dfrac{1000}{80}= 13 \ \text{items}\)

\(= 13 \times \$80\)

\(= \$1040\)

Thus,

\(1040 \times(1-30\%)\times(1- 25\%)\)

\(=1040 \times0.7\times0.75\)

\(= \$\bold{546}\)

Hence, the total price is $546.

Therefore, the future value of a three-year uneven cash flow given below, using an 11% discount rate is $1,238.82.

To calculate the future value of a three-year uneven cash flow given below, using an 11% discount rate, we need to use the formula;

Future value of uneven cash flow = cash flow at year 1/(1+discount rate)¹ + cash flow at year 2/(1+discount rate)² + cash flow at year 3/(1+discount rate)³ + cash flow at year 4/(1+discount rate)⁴

Given the cash flows;

Year 0: $0

Year 1: $600

Year 2: $500

Year 3: $400

Then the Future value of uneven cash flow

= $600/(1+0.11)¹ + $500/(1+0.11)² + $400/(1+0.11)³

= $600/1.11 + $500/1.23 + $400/1.36

=$540.54 + $405.28 + $293.00

=$1,238.82

Therefore, the future value of a three-year uneven cash flow given below, using an 11% discount rate is $1,238.82.

The equation of the line is y = 2x + 8 that is parallel to the given line y = 2x + 2 and passes through the point (−3, 2)

An equation is an expression that shows the relationship between two or more numbers and variables.

The equation of a straight line is:

y = mx + b

Where m is the rate of change and b is the y intercept.

Two lines are parallel if they have the same slope.

Let us assume that the line is parallel to y = 2x + 2 and passes through the point (−3, 2).

The slope of the line y = 2x + 2 is 2, Since it is parallel, the slope is also 2. hence:

y - y₁ = m(x - x₁)

y - 2 = 2(x - (-3))

y - 2 = 2(x + 3)

y = 2x + 8

An equation of the line that is parallel to the given line and passes through the point (−3, 2) is: 4x + 3y = -6.

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

By critically observing the graph (see attachment), we can logically deduce that the line passes through the following points:

Points (x, y) = (3, -1)

Points (x, y) = (0, 3)

Substituting the given parameters into the formula, we have;

Slope, m = (3 + 1)/(0 - 3)

Slope, m = 4/-3

Slope, m = -4/3.

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂ ⇒ -4/3 = -4/3

Note: m represents the slope.

At point (-3, 2), an equation of the other line can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

Substituting the given points into the formula, we have;

y - y₁ = m(x - x₁)

y - 2 = -4/3(x - (-3))

y - 2 = -4/3(x + 3)

y - 2 = -4x/3 - 4

y - 2 = -4x/3 - 4 + 2

y = -4x/3 - 2

Multiplying all through by 3, we have:

3y = -4x - 6

Rearranging the equation, we have:

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

The probability of selecting exactly one defective calculator out of the 6 sent to the local high school can be calculated using the binomial probability formula. The binomial probability formula is \(P(x) = nCx * p^x * q^(n-x)\). For this problem, n = 6 (the number of calculators sent to the local high school), x = 1 (the number of defective calculators selected), p = 4/12 (the probability of selecting a defective calculator from the shipment of 12 calculators), and q = 8/12 (the probability of selecting a non-defective calculator from the shipment of 12 calculators). Plugging these values into the formula gives \(P(x) = 6C1 * 4/12^1 * 8/12^5\), which simplifies to 0.29166. This means that the probability of selecting exactly one defective calculator out of the 6 sent to the local high school is 0.29166.

The total distance traveled is 46 miles.

Distance Traveled:

Distance traveled is the path covered by a body to get from a starting point to an endpoint in a certain period of time, at a certain velocity. Time and velocity play a major role in measuring the distance traveled. The distance travel formula is: d = v x t

To determine the total distance you have traveled, you will need to add up all the distances you have driven in each direction.

You drove 10 miles north, 14 miles east, 16 miles north, and 2 miles east, 4 miles north.

The decision to reject or not reject the null hypothesis depends on the chosen significance level. The smaller the significance level, the stronger the evidence needed to reject the null hypothesis.

In hypothesis testing, the significance level is the probability of rejecting the null hypothesis when it is true. It is usually set at 0.05 or 0.01. The P-value is the probability of obtaining a test statistic as extreme as the one observed, assuming the null hypothesis is true.

For a P-value of 0.081, we can say that there is some evidence against the null hypothesis but not strong enough to reject it.

If the significance level is set at 0.05, we should not reject the null hypothesis because the P-value is greater than the significance level.

However, if the significance level is set at 0.10, we may choose to reject the null hypothesis because the P-value is equal to or less than the significance level.

For part a, since the alpha level is 0.10, the null hypothesis should be rejected if the P-value is less than or equal to 0.10. Since the P-value is 0.081, which is greater than 0.10, we do not reject the null hypothesis. Therefore, the answer is B.

For part b, since the alpha level is 0.05, the null hypothesis should be rejected if the P-value is less than or equal to 0.05. Since the P-value is 0.081, which is greater than 0.05, we do not reject the null hypothesis. Therefore, the answer is C. In hypothesis testing, the null hypothesis is a statement that assumes there is no significant difference between the sample data and the population data. The hypothesis test is used to determine the validity of the null hypothesis by calculating the probability of observing the sample data if the null hypothesis is true. The significance level is the threshold value used to determine whether to reject the null hypothesis. It is usually set to 0.05 or 0.01. The P-value is the probability of obtaining a test statistic as extreme as or more extreme than the one observed, assuming the null hypothesis is true. If the P-value is less than or equal to the significance level, we reject the null hypothesis. Otherwise, we do not reject it.

The least appropriate measure of central tendency for a data set that contains outliers is the mean. This is because the mean is calculated by taking the sum of all the values in the data set and dividing it by the number of values. This means that the mean is heavily influenced by outliers, as they are included in the calculation.

The median, 2nd quartile, and 50th percentile are all more appropriate measures of central tendency for a data set that contains outliers, as they are not affected by the presence of outliers. The median is calculated by taking the middle value of the data set, the 2nd quartile is calculated by taking the median of the upper half of the data set, and the 50th percentile is calculated by taking the value at the 50th percentile of the data set.

a) The effective rate of interest on a mortgage at 8.15 percent compounded semi-annually is 8.23 percent.

b) It will take approximately 54.4 years to save $1,000,000 for retirement with $200 monthly deposits at 6 percent interest compounded monthly.

a) To find the effective rate of interest, we use the formula: Effective Rate = (1 + (Nominal Rate / Number of Compounding Periods))^Number of Compounding Periods - 1.

For a mortgage at 8.15 percent compounded semi-annually, the nominal rate is 8.15 percent and the number of compounding periods is 2 per year.

Plugging these values into the formula, we get Effective Rate = (1 + (0.0815 / 2))^2 - 1 ≈ 0.0823, or 8.23 percent. Therefore, the effective rate of interest on the mortgage is 8.23 percent.

b) To determine how long it will take to save $1,000,000 for retirement with $200 monthly deposits at 6 percent interest compounded monthly, we can use the formula for the future value of an ordinary annuity: FV = P * ((1 + r)^n - 1) / r, where FV is the future value, P is the monthly deposit, r is the monthly interest rate, and n is the number of periods.

Rearranging the formula to solve for n, we have n = log(FV * r / P + 1) / log(1 + r). Plugging in the values $1,000,000 for FV, $200 for P, and 6 percent divided by 12 for r, we get n = log(1,000,000 * (0.06/12) / 200 + 1) / log(1 + (0.06/12)) ≈ 54.4 years.

Therefore, it will take approximately 54.4 years to save $1,000,000 for retirement under these conditions.

Given the number line, it appears that in every 1/2 of a number, there are 5 bars in it. And in every 5 bars, 4 bars were shaded.

Adding the number of shades, we get:

4 + 4 + 4 = 12

Adding the total number of bars, we get:

5 + 5 + 5 = 15

The total number of bars sums up to be 3/2 in the number line.

Putting this into an equation, we get:

Therefore, the answer is 4/5 of 3/2. It is letter B.

The differential equation is equivalent to

                           \(\frac{dy}{dx} -\frac{3x(1-y)}{x^{2} +1}\)

If y denotes the fraction of the population who have heard the rumor, then 1 −y represents the fraction of the population who haven’t heard the rumor.

The rate of spread of the rumor (y'(t)) being proportional to the product of the fraction y of the population who have heard the rumor and the fraction who have not heard the rumor can then be rewritten as:

\(\frac{dy}{dt} =ky(1-y)\)

for some positive constant k. This is a separable differential equation, so to solve it we separate the variables

\(\frac{dy}{y(1-y)} =kdt\)

and integrate

\(\int\ \frac{dy}{y(1-y)} =\int k dt < = > ln |\frac{y}{1-y} |=kt+c\)

Exponentiating, we get

\(|\frac{y}{1-y}|=e^{kt+c}\)

Denoting ec by A, and taking into account that y ∈ (0, 1) we get

\(\frac{y}1-{y} =Ae^{kt} =\frac{Ae^{kt} }{1}\)

Adding the numerators to the denominators in the above equality of fractions we obtain

\(y=\frac{y}{(1-y)+y} =\frac{Ae^{kt} }{1+Ae^{kt} }\)

The Initial value:

\((x^{2}+1) \frac{dy}{dx} +3y(y-1)=0,y(0)=1\)

The differential equation is equal to

\(\frac{dy}{dx} -\frac{3x(1-y)}{x^2+1}\)

the initial condition of our problem is y(0) = 1, the solution must be y ≡ 1

The differential equation is equivalent to

\(\frac{dy}{dx} +\frac{3x}{x^2+1} y=\frac{3x}{x^2+1}\)

which is a linear equation, with P(x) = Q(x) =\(\frac{3x}{x^2+1}\) we have

\(\int P(x)=\frac{3}{2}\int \frac{2x}{x^2+1} dx=\frac{3}{2} ln(x^2+1)\)

It follows that the integrating factor I(x) is then

\(I(x)e^{\int P(x)dx} =e^{\frac{3}{2} ln(x^2+1)} =(x^2+1)^{\frac{3}{2} }\)

The general technique for solving linear differential equations yields

\(yI(x)=\int Q(x)I(x)dx=\int \frac{3x}{x^2+1} (x^2+1)^{\frac{3}{2} } \\\\=\int 3x(x^2+1)^{\frac{1}{2} } =(x^2+1)^{\frac{3}{2} } +C\)

Dividing by I(x) we get

\(y=1+\frac{C}{(x^2+1)^{\frac{3}{2} } }\)

The initial condition y(0) = 1 yields 1 = 1 + c, i.e. c = 0. Therefore y ≡ 1.

The differential equation is separable. We get this by separating the variables

\(\frac{dy}{y-1} -\frac{-3x}{x^2+1}\)

Integrating, we obtain

\(ln|y-1|=\frac{-3}{2} ln(x^2+1)+c\)

which yields by exponentiation

\(|y-1|=\frac{e^c}{(X^2+1)^\frac{3}{2} }\)

substituting ec by a constant A, and allowing A to also be negative or 0, we get

\(y-1=\frac{A}{(x^2+1)^\frac{3}{2} }\)

The initial condition y(0) = 1 implies that 1 − 1 = A/1 = A, hence A = 0 and          y ≡ 1
