In Mr. Britt's class the distribution of ages of his students has a mean of 115 months and a standard
deviation of 3.6 months.
If no students leave or join the class, what will be the mean and standard deviation of the distribution of
student's ages 4 months later?
Using statistical concepts, it is found that the mean will be of 119 months, while the standard deviation will be of 3.6 months, given by option C.
-------------------------------------
The mean of a data-set is the sum of all values divided by the number of values.The standard deviation is the square root of the sum of the difference squared of each observation and the mean, divided by the number of values.If x is added to all values of a data-set, it is also added to the mean, while the standard deviation remains constant.-------------------------------------
Mean of 115 months and standard deviation of 3.6 months.4 months later is the same as adding 4 to each observation.Thus, the mean will be of 115 + 4 = 119 months, while the standard deviation remains constant at 3.6 months.A similar problem is given at https://brainly.com/question/20640860
Answer:
Mean: 119119119 months
Standard deviation: 3.63.63, point, 6 months

Tap A fills 10/11 of a bottle in a minute. Tap B fills 3 4/5 times as many bottles as Tap A in a minute. Find the number of bottles Tap B fills in a minute.
Answer:
3 5/11
Step-by-step explanation:
Tap A's rate is (10/11) bottle/min.
Tap B's rate is 3 4/5 = 19/5 times that of tap A. Then tap B's rate is ...
(19/5)(10/11) bottles/min = 38/11 bottles/minute
Tap B fills 3 5/11 bottles in a minute.

Step-by-step explanation:
An angle measures 143.4° less than the measure of a supplementary angle. What is the measure of each angle?
Measure of an angle = x
Measure of another angle = x - 143.4
Each angle is the supplement of the other angle .
Which means :-
[tex]x + x - 143.4= 180[/tex]
[tex]2x - 143.4 = 180[/tex]
[tex]2x = 180 + 143.4[/tex]
[tex]2x = 323.4[/tex]
[tex]x = \frac{323.4}{2} [/tex]
[tex]\color{hotpink}x = 161.7[/tex]
Then :-Measure of the first angle :-
[tex]\color{hotpink} = 161.7°[/tex]
Measure of the second angle :-
[tex] = x - 143.4[/tex]
[tex] = 16.7 - 143.4[/tex]
[tex]\color{hotpink} = 18.3°[/tex]
As the sum of the measure of each angle adds up to 180° (161.7+18.3=180) , we can conclude that we have found out the correct value of each of the angles .
Therefore , the measure of the first angle is = 161.7° and the measure of it's supplementary angle is = 18.3° .

The suspect was spotted riding the swings earlier in the day. Each swing can hold a maximum weight of 500 pounds. In order to reach the maximum weight, you would have to double the weight of the suspect and add 20 pounds less than the weight of George. Write and solve an equation to represent the suspect's weight.
Answer:
2y + ( x- 20)= 500
y= 520-x/2
Step-by-step explanation:
Let the weight of George be x and the weight of the suspect be y .
The swing can hold a maximum of 500 pounds .
Twice the weight of suspect added with 20 pounds less than the weight of George equals 500.
2y + ( x- 20)= 500
or
2y+x- 20 = 500
adding 20 to both sides
2y+x -20 +20= 500+ 20
or
2y +x = 520
Subtracting x from both sides
2y+ x-x = 520-x
or
2y = 520-x
Dividing by 2 on both sides
y= 520-x/2
The suspect's weight is y= 520-x/2
Answer:
s = 260 - g/2
Step-by-step explanation:
Given the following :
Maximum weight swing can hold = 500 pounds
Let suspect's weight = s
George's weight = g
To reach maximum weight :
Double weight of suspect + (George's weight - 20)
Hence, equation:
2s + (g - 20) = 500
2s + g - 20 = 500
2s + g = 500 + 20
2s + g = 520
2s = 520 - g
Divide through by 2
s = 260 - g/2

On Monday morning Sergio Pappas had $14.78 in cash.
During the week he earned $45.00 for cutting lawns
and $35.75 for yard work, and he spent $25.23 on food
and $22.12 on gas.
# Problem Solution
a. What were Sergio's total earnings for the week?
b. What total amount did he have to spend during the week?
c. What was his balance at the end of the week?
( please do not comment if you do not know the answer, would be appreciated )
Answer:
Step-by-step explanation:
a-As he had earned $45.00 for cutting lawns and had earned $35.75 for yard work during the week and had not earned more than that, in order to find the total amount of money he earned during the week, we have to add $45.00 and $35.75 together which will be $80.75. So we can say that he had earned $80.75 during the week.
b- Since he had spent $25.23 on food and $22.12 on gas, we have to add them to get the total amount of money spend during the week. So after adding the amount of moneys spent, we will get $47.35.
c- Finally, to find out how many money he was left with, we have to subtract the amount of moneys spent from the total amount of earnings for the week. So, after subtracting $47.35 from $80.75 he is left with $33.4.
