Answer:
0 7
Step-by-step explanation:
at the Y- intercept the value of x is zero
Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_

, where
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :


[Round to next integer.]
Hence, the required minimum sample size = 18
Answer:

Step-by-step explanation:
The general rule we are going to use to multiply this out is the distributive property. Which is:
a(b+c) = ab + ac
<u>Note:</u> x * x = x^2
Now multiplying, we get:

This is the multiplied out form, answer.
Check the picture below.
so, bearing in mind that vertical angles are equal, thus ∡AED = ∡BEC, and we know that ∡BEC = 52 = ∡AED, so those two angles added up are 104°.
now, a circle has a total of 360°, if we take away those 104° from the red angles, what's leftover is just 256°, well, the green angles there are also vertical angles and thus twins, so each one will take half of 256°.
∡BEA = 128° = ∡CED.
gas mileage = k*s, where k is a constant of proportionality and s is the speed. Unfortunately, this does not take into account the fact that the engine consumes fuel even when the car is not moving.
Here it makes most sense to regard {0, S} as the domain for this function. Here, S would represent the car's top speed.
