The areas of a rectangle is lxw. You simply multiply by 3 x 6 and get this answer.

Answer: 2^3 x 2^4

Step-by-step explanation:

The value of the exponential expression is A = 2³.2⁴ = 128

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the value of the exponential equation be A

Now , the first expression is p = 2³

The value of p = 8

Now , the second expression is q = 2⁴

The value of q = 16

From the laws of exponents , we get

p.q = 2³.2⁴ = 2³⁺⁴

The value of A = 2⁷ = 128

Hence , the exponential equation is 2⁷ = 128

Answer:

Kevin made 5 free throws and 3 two-point shots.

Step-by-step explanation:

Given that Kevin scored 11 points in his last basketball game, to determine if Kevin made two more free throws (one point each) than two-point shots how many of each shot did he make, the following calculation must be performed:

11 x 1 + 0 x 2 = 11

6 x 1 + 4 x 2 = 14

5 x 1 + 3 x 2 = 11

Therefore, Kevin made 5 free throws and 3 two-point shots.

Answer:

b = 12

Step-by-step explanation:

c^2 = a^2 + b^2

Solving for b,

b^2 = c^2 - a^2

= (13)^2 - (5)^2

= 169 - 25

= 144

Answer:

Since the calculated value of F=0.20  does not fall in the critical region

F ≥  = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.

Step-by-step explanation:

As the sample size are different we can run anova in the excel.

Part a)

The null and alternate hypotheses are

H0: μ1=μ2=μ 3  against the claim Ha: Not all three means are equal

The significance level ∝ is chosen to be 0.05

Part b)

The critical region is F≥ F(0.05,5,9) = 3.481

Part c) SST, SSE, and SS total

Answer:

A. -21

Step-by-step explanation:

y varies directly as x

y = kx

----------------------

y = 15 when x = -5

Find k, the constant of variation

15 = k(-5)

Divide both sides by -5

-3 = k

k = -3

------------------------------

y when x= 7

using k = -3

y = -3(7)

y = -21

342 + D = 90

Step-by-step explanation:

We can deduce the following from the statement;

- D is added to 342 so as to make it greater.

- The resulting value is the same as 90 i.e equal in value to 90.

Translating the word problem into an algebraic expression, we have;

342 + D = 90

Answer:

Since the calculated value of z= -1.0198 does not lie in the critical region  z = ± 1.96 the null hypothesis is accepted and it is concluded that the  average monthly cost for childcare outside the home for a single child is $600.

P- value  ≈ 0.307823 which supports the null hypothesis .

Step-by-step explanation:

The null and alternate hypotheses are

H0: u = $600   the average monthly cost for childcare outside the home for a single child is $600.

against the claim

Ha:  u ≠ $600 the average monthly cost for childcare outside the home for a single child is  not equal to $600.

The significance level is set at 0.05

3) The critical region is  z =  ±1.96

4) The test statistic

Z=x- u /s/√n

z= 589-600/40/√14

z= -11/10.7681

z= -1.0198

6) Conclusion

Since the calculated value of z= -1.0198 does not lie in the critical region  z = ± 1.96 the null hypothesis is accepted and it is concluded that the  average monthly cost for childcare outside the home for a single child is $600.

P- value  ≈ 0.307823 which supports the null hypothesis .

x = 15/2

Step-by-step explanation:

Step 1: Add 1 to both sides.

2/3x − 1 + 1 = 4 + 1

2/3x = 5

Step 2: Multiply both sides by 3/2.

(3/2) * (2/3x) = (3/2) * (5)

x = 15/2

Given the inequalities as

y>-2x+3

y<1/2x-2

Graph the inequalities on the graph tool

The solution is  points in the shaded area such as (2,2),(4,4),(4,2),(2,-2),(2,-4)

The point (-2,3) is not included in the solution area because it is located in the un-shaded area.

Mathematically, taking points (-2,3) into the inequality

y>-2x+3

3>-2(-2) +3
