Answer:
1/2
Step-by-step explanation:
1.25 is the slope 5/4 rise over run
Answer:
slope = y = 1/2
y-intercept = b = -3
Step-by-step explanation:
slope intercept equation:
y = mx + b----->(equation 1)
m is slope
b is y-intercept
y = 1/2x - 3----->(equation 2)
Compare (equation 1) and (equation 1)
slope = y = 1/2
y-intercept = b = -3
Answer:
Step-by-step explanation:
Data given and notation
represent the sampe size for A
represent the sample size for B
represent the sample deviation for A
represent the sample deviation for B
represent the significance level provided
F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:
Solution to the problem
System of hypothesis
We want to test if we have the same variation, so the system of hypothesis are:
H0: 
H1: 
Calculate the statistic
Now we can calculate the statistic like this:
Answer:
$244
Step-by-step explanation:
f(x) = 60x + 4 and g(x) = 2x-4
We are told to find f(g=4), when Mike makes four tables.
We have to put replace x in f(x) with the value g(x) when x is 4, like this:
f(x) = 60x + 4 // Replace x with g(x) = 2x-4
f(x) = 60(2x-4) + 4
f(x) = (120x - 240) + 4 // Solve
f(x) = (120*4 - 240) +4 // They tell us x=4
f(x) = 480 - 240 + 4 = $244
