A=18
Explanation:multiply both sides by 3 to get rid of the fraction so u are left with a=18
<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:
The box of 10 for $10.88 is better.
Step-by-step explanation:
10.88/10=$1.08
17.62/14=$1.26
Answer:
- B) y = negative 4 x + three
Step-by-step explanation:
<u>Find the slope of the line that goes through (0, 8) and (2, 0):</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (0 - 8) / (2 - 0) = -8/2 = -4
Parallel lines have equal slopes.
<u>Looking at the choices we see only one of them has the slope of -4:</u>
Answer:
R(s)
,
Step-by-step explanation:
The function R(s) = 20s
She needs to sell at least 100 subscriptions, so the least amount she wants to have is: 20*100 = $2000
Hence, is the domain of R(s) in this context
R(s)
