Combined perimeters of the triangle and square will be 148 inches

Step-by-step explanation:

An equilateral triangle has all its sides have equal length. The perimeter is 3l where l is length of one side.Given the perimeter of the equilateral triangle as 63 inches then,finding the length of each side will be:

3l=63

l=63/3=21 inches.

Square has its lengths 2 inches shorter than each side of triangle,this will be;

21-2=19 inches

Perimeter of the square will be 4l = 4*19=76 inches

In the new triangle 3 inches are added to each side,thus the new side will be;

21+3=24 inches.

New perimeter of triangle will be: 3l = 3*24=72 inches

The new combined perimeter will be 76+72=148 inches.

Genrish500 [490]

Answer:

there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

Step-by-step explanation:

Given that:

A marketing organization claims that more than 10% of its employees are paid minimum wage.

The null hypothesis is:

H_o : p = 10

The alternative hypothesis is:

H_1 : p > 10

If a hypothesis test is performed that fails to reject the null hypothesis, how would this decision be interpreted

i.e Decision Rule: fails to reject the null hypothesis

Then the interpretation of the decision is that, there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

avanturin [10]
M + t = 26
m = t - 6

t - 6 + t = 26
2t - 6 = 26
2t = 26 + 6
2t = 32
t = 32/2
t = 16 <== Trevor has 16

m = t - 6
m = 16 - 6
m = 10...and Marissa has 10
