Answer: D
y = mx + b
y = 2x - 4
Slope = 2
y-intercept = -4 = (0,-4)
Answer: 25%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. if we want to write 1/4 as a percent, we need to find a fraction equivalent to 1/4 with a 100 in the denominator. We can do this by setting up a proportion.
=
4n = 100
÷4 ÷4
n = 25
Therefore, 1/4 is equivalent to 25%.
Answer:
Step-by-step explanation:
We know that the mean and standard deviation of the sampling distribution of the sample proportion() is given by :-
, where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
Now , the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 will be :
Hence, the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 are :
Independent variables are things that can stand alone. Which set of these variables does not rely on each other? For example the income and savings. I want 1,000,000 in my savings account, however my income is not nearly that high since I only make 19,000. Look at the other pairs and see if there is a correlation between them.
