Answer:
y = 5/7x + 83/7
Step-by-step explanation:
y-9=5/7(x--4) **x--4 turns into x+4 bc its a double negative**
y-9=5/7x + 20/7
y= 5/7x + 83/7
0.12r=1.8
Divide both sides by 0.12
r = 15
Answer:
Yes
Step-by-step explanation:
y=3.7x starts with a (0,0) and it is a straight line nonetheless.
It isn't zig zag line and is a proportional relationship.
Eight below zero would express the value -8, negative eight,
but not 8.
Answer:
Step-by-step explanation:
From the information given, we would write the hypothesis.
For the null hypothesis,
H0 : µ = 70
For the null hypothesis,
Ha : µ > 70
This is a right tailed test because of the symbol of greater than.
The decision rule is to reject the null hypothesis if the level of significance is greater than the p value and accept the null hypothesis if the level of significance is lesser than the p value.
Therefore, since the significance level, 0.05 > p value, 0.01635, then we would reject the null hypothesis. There is enough evidence that the mean speed of all cars is greater than the posted speed limit of 70 mph.
