He will need 135 more points to allow him to have an A in the class
125.
16 (10 and 6) divided by 100 is 6.25. Times two is 12.5. (For 200) times 10 for 10 marbles.
Answer:
F 904.32in ^3
Step-by-step explanation:
first use find the radius, which is always half the diameter, in this case 6.
then use the formula, knowing the radius is 6
the cube the radius
multiple radius by 4/3
then multiply by pi
Answer is 3 because it is the greatest common factor
Answer:
95.86% probability that the sample proportion will differ from the population proportion by less than 3%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
For a proportion, we have that:
What is the probability that the sample proportion will differ from the population proportion by less than 3%
This is the pvalue of Z when X = 0.07 + 0.03 = 0.1 subtracted by the pvalue of Z when X = 0.07 - 0.03 = 0.04. So
X = 0.1
has a pvalue of 0.9793
X = 0.04
has a pvalue of 0.0207
0.9793 - 0.0207 = 0.9586
95.86% probability that the sample proportion will differ from the population proportion by less than 3%
