5x+25 final answer is x=5
<em>10 inches</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em><u>volume of a sphere formula</u></em>
<em>V = 4π·r³/3</em>
<em>3V = 4π·r³</em>
<em>r³ = 3V/4π</em>
<em>replace</em>
<em>r³ = (3·500π/3)/4π</em>
<em>= 500π/4π</em>
<em>= 125</em>
<em>r³ = 125</em>
<em>r³ = 5³</em>
<em>r = 5 inches</em>
<em>d = 2r = 2×5in = 10 inches</em>
<em>Good luck !</em>

Answer:
1.32% of students have the chance to attend the charter school.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be 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.
This year the mean on the entrance exam was an 82 with a standard deviation of 4.5.
This means that 
a.What is the percentage of students who have the chance to attend the charter school?
Students who achieve a score of 92 or greater are admitted, which means that the proportion is 1 subtracted by the pvalue of Z when X = 92. So



has a pvalue of 0.9868
1 - 0.9868 = 0.0132
0.0132*100% = 1.32%
1.32% of students have the chance to attend the charter school.
It looks as though the formula is right there.
