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

Answer:
15/31 is the answer.
Step-by-step explanation:
-75 = -5d- 150d
-5d- 150d= - 155d
divide -75 from -155d
-155d / -155= -75 / -155
=15 / 31

Calculate the mean of Bryanna's test scores if she has scored 75, 97, and 92 so far this
semester
A 284
o
B
88
c. 75
D
Work Shown:
Add up the values
75+97+92 = 264
Then divide by 3 since there are 3 scores
264/3 = 88
You can write this all as one step
(75+97+92)/3 = 88
So in short, you add the scores and then divide by the number of scores.

Whats the Square root of 13?
Answer:
3.25
Step-by-step explanation:
Go 3.25 units of distance in any direction. Turn 90 degrees clockwise and go 3.25 units of distance in a straight line. Turn 90 degrees clockwise and go 3.25 units of distance in a straight line. Turn 90 degrees clockwise and go 3.25 units of distance in a straight line.
You will have travelled along a square route whose total distance is 13 units. Alternatively you could have turned counter clockwise each time.

Which is not a prime number? A. 31 B. 47 C. 49 D. 53
Answer:
49 is not a prime number
Step-by-step explanation:
7 times 7 = 49
Answer:
C) 49
Step-by-step explanation:
Prime numbers are numbers that can only be factored into 1 and it's own number.
In the case of 49, it is a composite number.
Factors of 49: 1 , 7 , 49
1 x 49 = 49
7 x 7 = 49
49 x 1 = 49

how many moles is 264.06 grams of carbon dioxide?
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° .
Graph the line with slope of 4/3
and goes through the point (1,3)
ANSWER THIS FAST!
Answer:
Step-by-step explanation:
y=4/3 x +b
goes through the point (1,3)
3=4/3(1)+b
b=3-4/3
b=9-4/3
b=5/3
equation : y=4/3 x +5/3
The graph of the line with slope of 4/3 and goes through the point (1,3) is shown in attached figure.
What is Equation of line?
The equation of line with slope m and passes through the point (x₁, y₁) is given as;
y - y₁ = m (x - x₁)
Given that;
The slope of line = 4/3
And, Point on line = (1, 3)
Since, The equation of line with slope m and passes through the point (x₁, y₁) is given as;
y - y₁ = m (x - x₁)
Thus, The equation of line with slope 4/3 and passes through the point (1, 3) is given as;
y - 3 = 4/3 (x - 1)
Solve as;
3 (y - 3) = 4 (x - 1)
3y - 9 = 4x - 4
3y = 4x - 4 + 9
3y = 4x + 5
y = 4/3x + 5/3
Thus, The equation of line will be;
y = 4/3x + 5/3
So, The graph of the line y = 4/3x + 5/3 is shown in attached figure.

3. A serving of a frozen casserole is 1/6 of a pan. If Vicky eats 1/7 of the pan, what fraction of a serving has Vicky eaten? Vicky has eaten of a serving (Type an integer or a simplified fraction.)
Answer:
[tex]x=\dfrac{6}{7}[/tex]
Step-by-step explanation:
A serving of a frozen casserole is 1/6 of a pan.
Vicky is 1/7 of the pan
We need to find the fraction of a serving has Vicky eaten. Let he has eaten x. It means (1/6) of x is equal to (1/7).
ATQ,
[tex]\dfrac{1}{6}x=\dfrac{1}{7}\\\\x=\dfrac{6}{7}[/tex]
So, he has eaten (6/7) of a serving Vicky eaten.
