F(x) = x² - 1
f(2a) = 35
f(2a) = (2a)² - 1 = 35
4a² - 1 = 35
4a² = 35 + 1
4a² = 36
a² = 36/4
a² = 9
a = √9
a = +3 or -3.
Answer:
x=y
Step-by-step explanation:
X= y becaus eit just does and y + x = n witch is the diameter of x
Answer:
Mean = 94
Standard deviation = 1.12
The sampling distribution of the sample mean is going to be normally distributed, beause the size of the samples are 80, which is larger than 30.
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, which is also called standard error 
In this problem, we have that:
By the Central Limit Theorem
The sampling distribution of the sample mean is going to be normally distributed, beause the size of the samples are 80, which is larger than 30.
Mean = 94
Standard deviation:
Answer: m = 3
Step-by-step explanation: convert to standard form 3x - y = -7
slope using standard form
Answer:
