The answer to this is y = 3x - 2.
In the slope-intercept form y=mx+b, b is your y-intercept and in this problem, it will be -2. M is the slope which is 3.
Let n = required random sample size.
Assume that the population standard deviation is known as σ.
Let m = sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.
Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²
This means that the sample size is about 128 times the population variance.
Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.
Answer:
∡J and ∡K are complementary
Step-by-step explanation:
since ∡L is a right angle, that means it measures 90 degrees
since there are a total of 180 degrees inside a triangle, angles J and K must add up to 90 which means they are complementary
To answer take 4 and multiply it by what is in the parenthesis (12x+48) after multiplying, take -36 and subtract 48 to get -84 and then divide -84 by 12x and your answer should be x=-7.
