At the U.S. Open Ternis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph.

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.

Shandra claims it will take them about 50 minutes working together, because 50 is the mean of 40 and 60. Which best describes Shandra’s claim?
Answer: CCCCCC
Step-by-step explanation:
It would take 24 minutes to sand the table working together.
What is an Equation?An equation is used to show the relationship between two or more variables and numbers.
It would take Shandra 40 minutes (2/3 hours) to sand a table while it would take kelly 1 hour.
Let t be the time it would take to sand the table working together. Hence:
(1/(2/3) + 1/1)t = 1
(3/2 + 1)t = 1
2.5t = 1
t = 0.4 hours = 24 minutes
It would take 24 minutes to sand the table working together.

The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.
Answer:
The first term is -3.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.
The nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.
If we have the mth term instead of the first, we have:
[tex]a_n = a_m + (n-m)d[/tex]
We have the third term, and need the fifth and the sixth:
So we write both the fifth and the sixth in function of the third, then:
[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]
[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]
The sum of the fifth and sixth term of an AP is 30
We use this to find [tex]d[/tex]. So
[tex]a_5 + a_6 = 30[/tex]
[tex]5 + 2d + 5 + 3d = 30[/tex]
[tex]5d + 10 = 30[/tex]
[tex]5d = 20[/tex]
[tex]d = \frac{20}{5} = 4[/tex]
First term:
The third term is:
[tex]a_3 = a_1 + 2d[/tex]
Since [tex]a_3 = 5, d = 4[/tex]
[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]
The first term is -3.
a can do a piece of work in 10 days, B in 12 days and C in 15 days how long will it take them it together to complete it.
Answer:
that would depend on how long the project is
A can do a piece of work in 10 days, B in 12 days and C in 15 days. How long will it take them it together to complete it ?
Explanation -:We observe here that A can do the work in 10 days; B can do the same work in 12 days whereas C can do the same work in 15 days. We are asked to calculate how much time will it take if three of them will work together.
We will solve this problem with traditional method.
Let us solve the question.
[tex] \small\pmb{ A's \: 1 \: day's \: work = \dfrac{1}{10}}[/tex]
[tex] \small\pmb{ B's \: 1 \: day's \: work = \dfrac{1}{12}}[/tex]
[tex] \small\pmb{ C's \: 1 \: day's \: work = \dfrac{1}{15}}[/tex]
[tex] \small\sf{ (A + B + C)'s \: 1 \: day's \: work = \frak {\dfrac{1}{10}+\dfrac{1}{12} + \dfrac{1}{15}}}[/tex]
L.C.M of 10, 12 and 15 is 60[tex] \longrightarrow \small\frak{ \dfrac{6 + 5 + 4}{60} } [/tex]
[tex] \longrightarrow \small\frak{ \dfrac{15}{60} = \dfrac{1}{4} } [/tex]
Hence A,B and C can finish the work in 4 days.[tex] \rule{40mm}{3pt}[/tex]

1. m+4>24
subtract both sides by 4
m>20
Two values that are greater than 20 are 21 and 22.
2. 7<x/4
multiply both sides by 4
28<x
Two values that are greater than 28 are 29 and 30.

Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.
[tex]\frac{70}{100} = \frac{x}{80}[/tex]
The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56
