Answer: The margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%)
Step-by-step explanation:
Given : A New York Times poll found that 47% of the women said they do not get enough time for themselves.
The poll announced a margin of error of ± 3% for 95% confidence in its conclusions.
A margin of error gives that value of percentage error of in results by which any random value will differ from the real population value.
Here the margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%).
Answer:
$7.50
Step-by-step explanation:
Find the Unit Rate, definition of Unit rate find the cost of 1 icecream.
Set up a ratio 6:22.50
Divide both by 6 to get 1:3.75
So 3.75x2=7
Answer:
There isn't enough buckets for all of the dirt to be in a bucket.
Step-by-step explanation:
From the question,
She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket.
Hence, the total number of dirt that can be in the 20 buckets is
20 × 2.56
= 51.20 pounds of dirt
Slyvia has 51.76 pounds of dirt.
51.76 - 51.20
= 0.56 pounds of dirt.
From the above calculation we can say that there isn't enough buckets for all of the dirt to be in a bucket
The height will be 4 cm.
Explanation
<u />The volume of a cylinder is given by the formula V=πr²h. For a volume of 36π cm³ and a radius of 3 cm,
36π = π(3²)h
36π = 9πh
Divide both sides by 9π:
36π/9π = 9πh/9π
4 = h
390, because 10% of 1300 is 130 so 130 times 3 = 390
