how many moles is 264.06 grams of carbon dioxide?
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

A number is written with a base and an exponent. What is
another name for the exponent?
-rational number
-base
-exponent
-power
Answer:
power
Step-by-step explanation:
The another name for the exponent is power, the correct option is D.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
Given;
A number is written with a base and an exponent
Now,
n exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself and exponent is also called index or power.
Therefore, the answer will be exponent.

Find the distance between the points (-3,7)
and
(6, 7).
Answer:
9
Step-by-step explanation:
use the distance formula:
[tex]\sqrt{(x2 -x1)^{2} + (y2-y1)^{2} }[/tex]
so, with your two points, x2=6, x1=-3, y2=7, and y1=7
so then just plug in the values
[tex]\sqrt{(6--3)^{2} + (7-7)^{2} }[/tex]
because you have 6 minus a negative number, it turns into 6+3, like shown
[tex]\sqrt{(6+3)^{2} + (7-7)^{2} }[/tex]
so then add and subtract the parenthesis
[tex]\sqrt{(9)^{2} + (0)^{2} }[/tex]
so then because 0 squared is just zero, you simply have the square root of 9 squared
[tex]\sqrt{9^{2} }[/tex]
so then square the 9
[tex]\sqrt{81}[/tex]
then take the square root of 81, and you get 9!
[note that when you have the square root of a squared number, it is just the number, so the square root of 9 squared is just 9, but if it helps, you can work it out like I did to show you :)]
The distance between the points (-3, 7) and (6, 7) is 9.
What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
Where (a, b) and (c, d) are the two points.
We have,
(-3, 7) = (a, b)
(6, 7) = (c , d)
Now,
Distance between these two points.
= [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
= √(6 + 3)² + (7 - 7)²
= √9²
= 9
Thus,
The distance between the points is 9.

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.

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.

Determine the domain of the graph above
what is 234 divided by 2 pls help me
Answer:
the answer 117
Step-by-step explanation:
The 234 divided by 2 is 117.
To calculate 234 divided by 2, we perform the division operation step by step.
Step 1: Divide 234 by 2.
234 ÷ 2 = 117
The result of 234 divided by 2 is 117. When you divide 234 by 2, you are essentially dividing 234 into two equal parts. Each part contains 117. This can be confirmed by performing the calculation:
234 ÷ 2 = 117
Therefore, 234 divided by 2 is 117. Division is the inverse operation of multiplication, and in this case, we find that 234 is evenly divisible by 2, resulting in a whole number quotient of 117.

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.
