If a is the number of balls Andre hit then a≥2j-20.
Answer:
The 95% confidence interval
Step-by-step explanation:
From the question we are told that
The sample mean is 
The standard deviation is 
The sample size is n = 8
Given that the confidence level is 95% then the level of significance is

=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as

=> 
=> 
Generally 95% confidence interval is mathematically represented as
=>
=>
Multiplying both sides of the equation by 3 and substituting 4 for p
Step-by-step explanation:
The picture is in sphere shape
so if you move it will be in the same position
The answer is
y^2-4x+4y-4=y^2+4y-4x-4=(y+2)²-4x - 8= 0
it is the same of x + 2 = (1/4 ) (y+2)²
the main formula is x-h= a (y-k)² so h=-2, k= - 2 and a=1/4
