Answer:
The slope is 2
Step-by-step explanation:
Y = mx+b y = mx+b is the shape of the slope-intercept where m is the slope.
Answer:
Step-by-step explanation:
$15 × 0.75 × 1.04 = $11.70
$25 × 0.75 × 1.04 = $19.50
$37 × 0.75 × 1.04 = $28.86
$65 × 0.75 × 1.04 = $50.70
Since there are 12 months in there year and there have already been 3 months there are 9 left
we need to multiply 4.25 by 9 and then add the first 15 inchess
4.25 times 9 = 38.25+15 = 53.25
Florida will recieve 53.25 inches of rain
I hope I've helped!
5/35 so 1/7 as a decimal this is .143. This is because it says D OR F which means add them and divide by 35. So your answer is 0.143
Answer:
A sample of at least 545 adults is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

The margin of error is:
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
If he wishes to be 95% confident that his estimate contains the population proportion, how large a sample will be necessary?
We need a sample of at least n.
n is found when M = 0.03. So




Rounding up
A sample of at least 545 adults is needed.
