The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
Answer:
We are given:
Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed
What parameter is being tested?
The parameter used is 
, which denotes the population mean.
Please note:
The type is test determined based on the alternative hypothesis.
If the alternative hypothesis has 
sign, it means the hypothesis test is two-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is right-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is left-tailed

Answer:
26
Step-by-step explanation:
GIRL 2/3's
2/3*39
2/3*39/1= 78/3 ( DIVIDE ) =26
2/3's of 39 =26
