This is volume of a sphere.
Answer: 3 26/50 or 3 52/100
Step-by-step explanation:
The rectangular bedspread measures 1 1/10 by 3 2/10. To know the length of fringe that Rebekah needs to buy for the whole bed, we multiply the figures given together since it's a rectangle.
Area of a rectangle= length × breadth
= 3 2/10 × 1 1/10
Change to improper fraction
= 32/10 × 11/10
= 352/100
= 3 52/100
Reduced to lowest term will be 3 26/50.
The length Rebekah needs to purchase is 3 52/100 or 3 26/50.
The probability that the sample proportion is within ± 0.02 of the population proportion is 0.3328
<h3>How to determine the probability?</h3>
The given parameters are:
- Sample size, n = 100
- Population proportion, p = 82%
Start by calculating the mean:
Calculate the standard deviation:
Within ± 0.02 of the population proportion are:
Calculate the z-scores at these points using:
So, we have:
The probability is then represented as:
P(x ± 0.02) = P(-0.43 < z < 0.43)
Using the z table of probabilities, we have:
P(x ± 0.02) = 0.3328
Hence, the probability that the sample proportion is within ± 0.02 of the population proportion is 0.3328
