Answer:
C. =
Step-by-step explanation:
Note the conversion for Yard to Feet.
1 yard = 3 feet.
In this case, it is given to you that there are 4 yards. Multiply 4 with 3 to get the amount of feet:
4 yd x 3 ft per yd = 12 feet per 4 yd.
12 ft. = 12 ft., ∴ 4 yd. = 12 ft.
Answer:1.50
Step-by-step explanation:
Answer:Prime factorization:
135 = 3 x 3 x 3 x 5, which can also be written 135 = 3³ x 5. 1 + 3 + 5 = 9. Nine is a multiple of both 3 and 9, so this quick divisibility trick lets us know that both 3 and 9 are factors of 135. 135 = 1⁵ x 3³ x 5¹.
<h3>Answer: B) 31.348</h3>
======================================
Work Shown:
We will never use the alpha = 0.05 value when computing the test statistic. So we can ignore alpha for this particular problem.
-------
n = 40 is the sample size.
s = 2.6 is the sample standard deviation
= sigma = 2.9 is the population standard deviation (ie the claimed standard deviation for all the pay phones)
Test Statistic for chi-square
Answer:
16.5
Step-by-step explanation:
The relationship between x and y is that y is just x+3.5. So if x is 13, then y is 13+3.5 which is 16.5.
