Answer:
D. 9
Step-by-step explanation:
When you add 1 + 4 + 5 + 5 + 5 + 6 + 9 + 10 + 10 + 11 + 12 + 12 + 15 + 15 + 15 = 135. Which is all of the numbers given to you, and since mean is when you add all of the numbers together, and than divide it by the amount of numbers there, you will take that 135 and divide it by 15. 135 / 15 = 9. Which gets you to finally getting an answer of 9. so D. 9 is correct.

jill calculates it would take 95 minutes to run 7 miles but it actually take 80 minutes what is percent of error
Answer:
15.8% = 16%
Step-by-step explanation:
The change (expected result - actual result):
95-80 = 15
Now we divide it by the expected 95 minutes and multiply by 100 to get a percentage.
15/95*100 = 15.8% = 16%

Step-by-step explanation:
Suppose you want to start saving for retirement. You decide to continuously invest $5000 of your income each year in a risk-free investment with a 7% yearly interest rate compounded continuously. If y| is the value of the investment, and t| is in years. dy/dt =| Your answer should be interms of y|. You start investing at t = 0| so y(0) = 0. y(t) =| What is the size of your investment after 40 years. y(40) =|
Answer:
The size of the investment after 40 years is of $74,872.
Step-by-step explanation:
Continuous compounding:
The amount of money, in continuous compounding, after t years, is given by:
[tex]y(t) = y(0)(1+r)^t[/tex]
In which y(0) is the initial investment and r is the interest rate, as a decimal.
You decide to continuously invest $5000 of your income each year in a risk-free investment with a 7% yearly interest rate compounded continuously.
This means that [tex]y(0) = 5000, r = 0.07[/tex]. So
[tex]y(t) = y(0)(1+r)^t[/tex]
[tex]y(t) = 5000(1+0.07)^t[/tex]
[tex]y(t) = 5000(1.07)^t[/tex]
What is the size of your investment after 40 years?
This is y(40), that is, y when t = 40. So
[tex]y(t) = 5000(1.07)^t[/tex]
[tex]y(40) = 5000(1.07)^{40}[/tex]
[tex]y(40) = 74872[/tex]
The size of the investment after 40 years is of $74,872.

1/2(n+4)=6 wat is n ?
Answer:
the correct answer is 8.
Answer:
n = 8
Step-by-step explanation:
1/2(n + 4) = 6
1/2n + 2 = 6
1/2n (+ 2 - 2) = 6 - 2
1/2n = 4
(2/1)1/2n = 4(2)
n = 8
CHECK WORK:
1/2(8 + 4) = 6
1/2(12) = 6
6 = 6
Rewrite each fraction with a denominator of 24 2/3 and 5/8
Answer:
2/3 = 16/24
5/8 = 15/24
Step-by-step explanation:
2/3= 16/24
5/8= 15/24
because if you multiply across [tex]\frac{2}{3}[/tex] by [tex]\frac{8}{8}[/tex] equal [tex]\frac{16}{24}[/tex]
and if you multiply across [tex]\frac{5}{8}[/tex] by [tex]\frac{3}{3}[/tex] equal [tex]\frac{14}{24}[/tex]
Convert 40% as a fraction and multiply the results by 25

(✯ᴗ✯)Hence , the answer is 10...(◍•ᴗ•◍)A study has been done to determine to see if the level of education determines how often people move between different states in America. If a person from the survey is randomly selected , what is the probability that they lived in 2 or more states and that they have a college degree? P( 2 state or more U Degree )
0.655
0.111
0.310
0.500
Solution :
P(2 states or more | college degree)
[tex]$=\frac{\text{P( 2 states or more and college degree)}}{\text{P(college degree)}}$[/tex]
Total number of people = 58
The number of people who lived in two states or more than two states and also have a college degree = 18
Therefore,
[tex]$\text{P(2 states or more states and college degree)} = \frac{18}{58}$[/tex]
The number of people who have a college degree = 20
So, [tex]$\text{P(college degree)} = \frac{20}{58}$[/tex]
Thus,
[tex]$\text{P(2 states or more/college degree)}=\frac{\frac{18}{58}}{\frac{20}{58}}$[/tex]
[tex]$=\frac{18}{20}$[/tex]
= 0.900

Which point lies on the graph of y = -x-5?
O A (-5,0)
OB. (4.-9)
OC (-2,-3)
OD. (3,-2)
Answer:
A, B and C are on the graph
Step-by-step explanation:
Just plug the values into y = -x - 5 and see if the y are equal
A ( -5, 0)
0 = 5 - 5
0 = 0
B (4, -9)
-9 = -4 - 5
-9 = -9
C (-2, -3)
-3 = 2 - 5
-3 = -3
D (3. -2)
-2 = -3 - 5

Select 3 numbers to get the sum of 30, the numbers are 1, 3, 5, 7, 9, 11, 13, 15
i think there is a trick so the 3 nbs are 9+11+13=33
How's that we need 30
if we flip 9 we get 6
so the answer would be 6+11+13=30

The zoo downtown has 9 times as many monkeys as elephants. They have 60 animals all together. How many elephants are there?
Answer:
6
Step-by-step explanation:
e = number of elephants
9 times as many monkeys as elephants
m = 9e
------------------------
60 animals all together
e + m = 60
e + 9e = 60
Combine like terms
10e = 60
Divide both sides by 10
e = 6
Answer: There’s technically no answer to this question, unless you specify that the zoo only has monkeys and elephants. If the zoo has more than two types of animal then the ratio doesn’t help because there are unknown variables.
However, if we knew that the zoo only has monkeys and elephants, then:
E = number of elephants
M = number of monkeys
M=9E
M + E = 60
9E+E= 60
10E = 60
E = 6
There are 6 elephants (and 54 monkeys).
