Answer:
The equation of line is y+2=0
Step-by-step explanation:
The equation of line passing through the point
and having slope m is

Given slope m=0 and given point is is (-2,-2)


therefore equation of the straight line is 
Therefore the straight is parallel to negative x-axis(y=-2)
Answer:
Yes
Step-by-step explanation:
The product of three polynomials will be a polynomial regardless of the signs of the leading coefficients of the polynomials.
Answer:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation 
So the correct answer is:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
Answer:0.235
Step-by-step explanation:
Take the decimal point and move it to the left twice and you get your answer
There’s 60 seconds in a min
