Volume problem.... Please help
vladimir1956 [14]

Answer:

c

Step-by-step explanation:

volume of cylinder = πr^2h

r = 6.5

h = 13+13+13 = 39

cylinder volume = 1647.75π cm^3

volume of one sphere = 4/3 π r^3

= 366.16π cm^3

space not occupied by tennis balls = 1647.75π-3(366.16π)=549.25π cm^3

Y intercept in the problem -2x+3y=1
Rina8888 [55]
The answer is 3y=1+2x
i say this because if the answer ain't telling you to solve for x the you just do this
-2x+3y=1
+2x     =1+2x which all u have to do now is drop the positive 3y 
which gives you 3y=1+2x

A standardized test has a mean of 110 points and a standard deviation of 10 points. John scored at the 98th percentile on the te
Mariana [72]

Answer: his score 131 points

Step-by-step explanation:

Assuming the scores in the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = standardized test scores.

µ = mean score

σ = standard deviation

From the information given,

µ = 110 points

σ = 10 points

Looking at the normal distribution table, the z score that corresponds to the 98 percentile is 2.06

2.06 = (x - 110)/10

Cross multiplying, it becomes

2.06 × 10 = x - 110

2.06 = x - 110

x = 20.6 + 110

x = 130.6

Approximately, x = 131
