Answer:

The value of x = 14/3

Step-by-step explanation:

Given the equation

\(3x-5 = 9\)

Add 5 to both sides

\(3x-5+5=9+5\)

Simplify

\(3x=14\)

Divide both sides by 3

\(\frac{3x}{3}=\frac{14}{3}\)

Simplify

\(x=\frac{14}{3}\)

Therefore, the value of x = 14/3

Using the normal approximation to the binomial, there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

This problem is incomplete, but researching it on a search engine, it asks the probability that the sum of these Bernoulli variables is of less than 60.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The binomial distribution is a series of n Bernoulli trials with p probability of a success on each trial, hence the parameters for the binomial distribution are given as follows:

n = 100, p = 0.5.

The mean and the standard deviation are given by:

Using continuity correction, the probability that the sum is less than 60 is P(X < 59.5), which is the p-value of Z when X = 59.5, hence:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (59.5 - 50)/5

Z = 1.9

Z = 1.9 has a p-value of 0.9713.

Hence there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

Answer:

The factored version of the given equation is going to be (3x² + 4y)(x + 5)

Step-by-step explanation:

3x³ + 15x² + 4xy + 20y

First, you break down 3x³. You can do this by finding the common factor of 3x³ and 15x². You can add the x to the other parentheses because x times x² equals x³

(3x² + )(x + 5)

Now, we break down 4xy by finding the common factor of 4xy and 20y.

(3x² + 4y)(x + 5)

So, the factored version of the equation above is (3x² + 4y)(x + 5)

Answer:

£187,500

Step-by-step explanation:

Cost of houses one year ago = £150000

Percent increase a year after = 25%

Increment = 25% * 150000

Increment = 0.25 * 150000

Increment = £37500

New cost of house after increment =  £150000+ £37500

New cost of house after increment = £187,500

Using her monthly income, Juliet's new monthly entertainment budget is approximately $183.33.

To calculate Juliet's new monthly entertainment budget, we need to find her total monthly income and then calculate 8% of that amount.

Let's assume her current monthly entertainment expenses, $275.00, account for 12% of her income. We can set up the following equation:

275 = 0.12 * income

To find her total monthly income, we can divide both sides of the equation by 0.12:

income = 275 / 0.12

income ≈ 2291.67

Now that we know her total monthly income is approximately $2291.67, we can calculate her new monthly entertainment budget by taking 8% of her income:

new budget = 0.08 * income

new budget = 0.08 * 2291.67

new budget ≈ $183.33

As tangents from a single point to the circle are equal in measure

ABC is isosceles

<A=60°

We know the radius hits any tangent on right angles

So

Now

accurate value

Answer:

\(x=4\sqrt{3}\)

Step-by-step explanation:

If two tangents to a circle meet at one exterior point, the tangent segments are congruent.   Therefore, AC = BC

This means that ΔABC is an isosceles triangle and so
∠ABC = ∠BAC = 60°

The tangent of a circle is always perpendicular to the radius.

Therefore, ∠PAC = 90°

With this information, we can calculate ∠PAD:

⇒ ∠PAD + ∠BAC = ∠PAC

⇒ ∠PAD + 60° = 90°

⇒ ∠PAD = 90° - 60°

⇒ ∠PAD = 30°

We now have a side length and an angle of ΔPAD (shown in orange on the attached diagram).  So using the cos trig ratio, we can calculate \(x\):

\(\sf \cos(\theta)=\dfrac{A}{H}\)

where:

Given:

\(\implies \cos(30^{\circ})=\dfrac{6}{x}\)

\(\implies x=\dfrac{6}{\cos(30^{\circ})}\)

\(\implies x=\dfrac{6}{\frac{\sqrt{3}}{2}}\)

\(\implies x=4\sqrt{3}\)

Answer: 1a. f(2) is an x-value

1b. f(x) = 4 is a y-value

1c. f(-10) is an x-value

1d. m(x) = 64 is a y-value

2.  f(4) = 17

3.  x = 39

Step-by-step explanation:  In general, if there is an equal sign, the output f(x) is a y-value. if the expression is f(#) with a number in the parentheses, that is the value to insert for x.

2.) f(x) = 2x + 9

f(4) = 2(4) + 9

f(4) = 8 + 9

f(4) = 17

3. f(x) = 5x -3

192 = 5x -3

192 + 3 = 5x

195 = 5x

39 = x

The exercise involves finding the product C = AB, where matrix A is given by [2 9] and matrix B is given by [3 6 1]. We need to perform the matrix multiplication to obtain the resulting matrix C.

Let's calculate the matrix product C = AB step by step:

Matrix A has dimensions 2x1, and matrix B has dimensions 1x3. To perform the multiplication, the number of columns in A must match the number of rows in B.

In this case, both matrices satisfy this condition, so the product C = AB is defined.

Calculating AB:

AB = [23 + 912 26 + 94 21 + 95]

[103 + 612 106 + 64 101 + 65]

Simplifying the calculations:

AB = [6 + 108 12 + 36 2 + 45]

[30 + 72 60 + 24 10 + 30]

AB = [114 48 47]

[102 84 40]

Therefore, the product C = AB is:

C = [114 48 47]

[102 84 40]

In summary, the matrix product C = AB, where A = [2 9] and B = [3 6 1], is given by:

C = [114 48 47]

Step-by-step explanation:

4x - y = 13 >>>> y = 4x - 13

2x + y = 17 >>>> y = -2x + 17

4x - 13 = -2x + 17

4x + 2x = 17 + 13

6x = 30

x = 5

y = 4x - 13 = 4(5) - 13 = 7

Answer:

It is c: 15.625 cm³

Step-by-step explanation:

Formular for cube volumes:

\({ \tt{volume = (side \times side \times side)}} \\ { \tt{v = (s_{1} \times s_{2} \times s_{3}) }}\)

since sides of a cube are identical:

\({ \sf{s_{1} = {s_{2} = {s_{3}}}}}\)

Therefore:

\({ \sf{volume = (250 \times 250 \times 250) \: mm {}^{3} }} \\ { \sf{v =15,625,000 \: {mm}^{3} }}\)

but 1 mm³ = 0.000001 cm³

\({ \sf{v = (15,625,000 \times \{1 \times {10}^{ - 6} \} ) \: cm}} \\ { \sf{v = 15.625 \: {cm}^{3} }}\)

The answer is not listed among the given options.To simplify the given expression, let's simplify each term separately and then combine like terms.

2√27√12 can be simplified as follows:

2√27 = 2√(3^3)

= 2(3√3)

= 6√3

√12 = √(2^2 * 3)

= 2√3

Therefore, 2√27√12 = 6√3 * 2√3

= 12 * 3

= 36.

Now let's simplify the remaining terms:

-3√3 remains the same.

-2√12 can be simplified as follows:

-2√12 = -2(2√3)

= -4√3.

Now, combining all the terms, the simplified expression becomes:

36 - 3√3 - 4√3.

Combining like terms -3√3 and -4√3, we get:

-7√3.

Therefore, the simplified form of the expression 2√27√12 - 3√3 - 2√12 is:

36 - 7√3.

Answer:

AC=42

thats all i know, sorry hope u figure it out

Step-by-step explanation:

The sides are AC = 42, EB = 21, BC = 26, AB = 38 and the measures of angles are ∠ADC = 90°, ∠ABD = 38°, ∠BCA = 52°, ∠DEC = 104°.

Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles

Given is a rectangle ABCD.

AC and BD are diagonals intersecting at E.

Given  DB=42, AD=26 and m ∠DAE=52°

(a) Diagonals of a rectangle are of equal length.

AC = DB = 42

(b) Diagonals of a rectangle bisect each other.

DE = EB = DB / 2 = 42/2 = 21

(c) Opposite side are equal.

BC = AD = 26

(d) Using Pythagoras theorem,

AB = \(\sqrt{(AC)^2-(BC)^2}\) = \(\sqrt{42^2-26^2}\) = 37.947 ≈ 38

(e) Measure of all the interior angles in a rectangle is 90°.

So, ∠ADC = 90°

(f) Given ∠DAE = 52°

∠BAE = 90° - 52° = 38°

ΔBAE is an isosceles triangle, since the two sides which are the bisectors of the diagonals are equal.

So, ∠ABD = ∠BAE = 38°

(g) ∠BCA = ∠DAE [Alternate interior angles]

∠BCA = 52°

(h) Sum of interior angles of a triangle is 180°.

∠DEC + ∠BDC + ∠ACD = 180°

∠BDC = ∠ABD = 38° and ∠ACD = ∠BAE = 38°

∠DEC = 180° - (38° + 38°)

          = 104°

Hence the measures are found.

By applying definition of ratios, the ratios associated to each pair of lengths:

In this problem we have the case of a geometric system generated by three proportional triangles, of which we must derive the length of ratio related to two similar sides. First, we determine the lengths of each line segment:

NR = √(2² + 2²)

NR = 2√2

NW = √(5² + 5²)

NW = 5√2

RT = 6

WH = 15

KX = 24

Lastly, we calculate the ratios associated with each pair of lengths according to the definition of ratio:

NR : NW = 2√2 : 5√2

NR : NW = 2 / 5 : 1

RT : WH = 6 : 15

RT : WH = 2 : 5

RT : WH = 2 / 5 : 1
