Answer:

6 inches

Step-by-step explanation:

Area = (base1 + base2)/2 · height

base1 = b

base2= 8

height = 3

Area = 21

21 = (b+8)/2 ·3

21 = 3(b+8)/2

multiply both sides by 2

42 = 3(b+8)

divide both sides by 3

14 = b+8

subtract 8 from both sides

b = 6 in

Find the lowest common denominator of and . A. x3y4 B. x2y3 C. xy4 D. x4y5

Blizzard [7]

Lowest Common Denominator refers to lowes t common multiple. These expressions have two terms 'x' and 'y' and we want to choose the expression that has the highest power such that the other expressions can be multiplied into the common denominator.

For the 'x' term, the highest power is x⁴ and for the 'y' term, the highest power is y⁵

Common denominator of A, B, C, and D: x⁴y⁵

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject H0

Leviafan [203]

Answer: We do not reject the null hypothesis.

Step-by-step explanation:

When the p-value is greater than the significance level , then we do not reject the null hypothesis or if p-value is smaller than the significance level , then we reject the null hypothesis.

Given : Test statistic : $z = -2.28$

Significance level : $\alpha=0.02$

By using the standard normal distribution table ,

The p-value corresponds to the given test statistic ( two tailed ):-

$2P(Z>|z|)=2P(Z>2.28)=0.0226$

Since the p-value is greater than the significance level of 0.02.

Then , we do not reject the null hypothesis.
