Answer:
For a pair of randomly selected in- and out-of-state students, the sum of their tuition typically varies from the mean of $6,348.75 by about $1,508.48.
Step-by-step explanation:
Given
Required
Interpret the standard deviations
In statistic, standard deviation is a measure of how the given data lies away (or varies) from the mean.
This implies that:
For the in-state students, the standard deviation measures how the sum of their tuition varies from 6348.75
For the out-state students, the standard deviation measures how the sum of their tuition varies from 1508
Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
This is the order of how to solve the problems. For this problem, we can start with parentheses since it has that in this equation.
5 x 6 ÷ (5)
The next step is to do Multiplication.
30 ÷ 5
Finally Division.
6
This is your final answer.
Hope that helps!

Step-by-step explanation:
a-c. The area formulas for these figures are ...
rectangular prism: A = 2(lw +h(l+w))
cylinder: A = 2πr(r +h)
sphere: A = 4πr^2
d. The total will be the sum of products: area of each pillow times the number of that type
__
e-g. The volume formulas for these figures are ...
rectangular prism: V = lwh
cylinder: V = πr^2h
sphere: V = (4π/3)r^3
h. As with area, the total volume is the sum of products: volume of each pillow times the number of that type.
Answer:
10/31
Step-by-step explanation:
Out of the total 62 skaters, 20 were not age 12 and were wearing rollerblades. 20/62=10/31. Hope this helps!
