What is a solution of the inequality 7 is less than or equal to -3x - 4

Answer:

C' (4,-6)

Step-by-step explanation:

Any point being reflected over the x-axis will undergo the following transformation:

(x, y) --> (x, -y)

(4, 6) --> (4, -6)

The coordinates of C',

C(4,6) → C'(4, -6).

A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.

Given:

Quadrilateral ABCD has coordinates A(-2,0), B(0,4), C(4,6), and D(2,2).

If it is reflected over the x-axis,

The reflection rule:

(x, y) → (x, -y)

The coordinates of C',

C(4,6) → C'(4, -6).

Therefore, the image point of C is C'(4, -6).

Step-by-step explanation:

The reduced fraction of 8/12 is 2/3. This means that out of the initial 12 cookies, 8 cookies are left.

To reduce the fraction 8/12, we need to find the greatest common divisor (GCD) of the numerator and denominator, which is the largest number that divides both numbers evenly. In this case, the GCD of 8 and 12 is 4.

Dividing both the numerator and denominator by the GCD, we get:

8 ÷ 4 / 12 ÷ 4 = 2/3

Therefore, the fraction 8/12 is equivalent to 2/3 when reduced.

In conclusion, after reducing the fraction, the fraction of cookies left is 2/3. This means that out of the initial 12 cookies, 4 were sold and there are now 8 cookies remaining.

Using the percentage-of-credit-sales method, Lindsey Corp. would report a bad debt expense of $40,000 for the year, assuming their total credit sales were $500,000 and they estimated 8% of those sales to be uncollectible.

Lindsey Corp. uses the percentage-of-credit-sales method to estimate their bad debt expense. According to their estimation, 8% of their credit sales are anticipated to be uncollectible. To calculate the bad debt expense for the year, Lindsey Corp. would follow these steps:

Multiply the total credit sales by the estimated percentage of uncollectible sales,

Next, Lindsey Corp. would multiply the total credit sales by the estimated percentage of uncollectible sales (8% in this case). This calculation gives us the anticipated amount of credit sales that are expected to become bad debts.

Mathematically, the formula would be:

Bad Debt Expense = Total Credit Sales * Percentage of Uncollectible Sales

If Lindsey Corp. had $500,000 in total credit sales for the year, the calculation would be:

Bad Debt Expense = $500,000 * 0.08 = $40,000

Finally, Lindsey Corp. would report the calculated amount as their bad debt expense for the year. This expense is recorded on the income statement to reflect the potential loss from uncollectible credit sales.

The valid sampling method that best describes the scenario in which a soccer club surveys 10 randomly selected season-ticket holders from each of 20 nearby townships to determine whether Tuesday or Wednesday matches are more popular is stratified random sampling.

What is stratified random sampling?

Stratified random sampling is a sampling method that involves dividing the population into several subgroups or strata and then selecting random samples from each stratum proportionately.

The goal is to ensure that each subgroup of the population is adequately represented in the sample.

To explain, in this scenario, the population of season-ticket holders is divided into subgroups or strata based on townships, and ten members are chosen from each stratum randomly.

This method ensures that a representative sample is selected, rather than choosing members from only one or a few townships and excluding others.

Step-by-step explanation:

Ron and Harry have ages that are consecutive odd integers. The product of their ages is 783. So, the ron's age r is 27.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Ron and harry have ages that are consecutive odd integers. The product of their ages is 783.

r is younger

r + 2 = s

product is 783

783 = rs

s = r +2

783 = r(r+2)

So, the quadratic equation form

783 = r^2 + 2r

0 = r^2 + 2r -783

0 = (r -27)(r +29)

set to zero

r-27 = 0

r = 27

and

r + 29 = 0

r = -29

thus, The age of ron is 27 years old.

The fine amount for a speed of 50 mph would be $235. the fine amount for a given speed (s) in North Washington, taking into account the excess speed over the limit and a base fine.

In a North Washington country, the formula to determine speeding fines is given by f(s) = 13(s - 35) + 40. Let's break down the formula and understand its components.

The formula represents the relationship between the fine amount (f) and the speed of the vehicle (s). The speed of the vehicle is denoted by the variable s.

The term (s - 35) represents the difference between the speed of the vehicle and the speed limit. By subtracting 35 from the speed of the vehicle, we obtain the excess speed over the limit.

Multiplying the excess speed by 13 indicates that the fine increases by $13 for every unit of excess speed over the limit.

Adding 40 to the product of 13(s - 35) ensures that there is a base fine amount, even if the excess speed is zero. The constant term of 40 represents this base fine.

Therefore, the formula f(s) = 13(s - 35) + 40 calculates the fine amount for a given speed (s) in North Washington, taking into account the excess speed over the limit and a base fine.

To determine the specific fine amount for a particular speed, substitute the speed value into the formula. For example, if the speed of the vehicle is 50 mph:

f(50) = 13(50 - 35) + 40

      = 13(15) + 40

      = 195 + 40

      = 235

In this case, the fine amount for a speed of 50 mph would be $235.

The circumference is 160 feet for a length of 40 feet. The perimeter is 200 feet for a length of 50 feet. The circumference is 240 feet for a length of 60 feet.

A rectangular region with a 1200 square foot area will have a different perimeter depending on how long it is. The perimeter will be 160 feet if the area is 40 feet long. The length of 40 feet is multiplied by four to get a final measurement of 160 feet. In a similar manner, if the area is 50 feet long, the perimeter will be 200 feet.

The length of 50 feet is multiplied by four to get a final result of 200 feet. Finally, the perimeter will be 240 feet if the area is 60 feet long. The length of 60 feet is multiplied by four to get a final measurement of 240 feet. A rectangular region with an area of 1200 square feet will therefore have a different perimeter depending on its length, with a length of 40 feet resulting in a perimeter of 160 feet, a length of 50 feet resulting in a perimeter of 200 feet, and a length of 60 feet resulting in a perimeter of 240 feet.

Answer:

587.18 in²

Step-by-step explanation:

In the above question, we are given the following values

Diameter = 11 inches

Radius = Diameter/2 = 11 inches/2 = 5.5 inches

Slant height = 28.5 inches.

We were asked to find how many square inches of paper will she need to cover the ENTIRE cone.

To solve for this, we would use formula for Total Surface Area of a Cone

Total Surface Area of a Cone = πrl + πr²

= πr(r + l)

Using 3.14 for π

Total Surface Area of a Cone

= 3.14 × 5.5( 5.5 + 28.5)

= 3.14 × 5.5 × (34)

= 587.18 in²

Therefore, Anita will need 587.18 square inches of paper to cover the entire cone.

The value of z-stat is -0.6721.

What is z stat?

The relationship between a value and the mean of a group of values is quantified by a Z-stat. The Z-stat is calculated using standard deviations from the mean. When a data point's Z-stat is 0, it means that it has the same score as the mean.

One standard deviation from the mean would be indicated by a Z-stat of 1.0. Z-stats can be positive or negative; a positive value means the score is above the mean, while a negative value means it is below the mean.

Solution Explained:

We use the formula,

\(z = \frac{P - \pi }{\sqrt{\frac{\pi (1-\pi )}{200} }}\), where P is the observed proportion, π is the hypothesized proportion

Therefore, P = 42/200 = 0.21 & π = 23/100 = 0.23

Putting the values in

\(z = \frac{0.21 - 0.23 }{\sqrt{\frac{0.23 (1-0.23)}{200} }}\)

After calculating, z-stat is therefore equal to -0.6721
