Hey there!
The mean of the numbers is the <u>average</u>. To find the mean we will simply add all the numbers together, and divide them by the amount of numbers there are. Easy, peesy, lemon squeezy. Lets get started.
7 + 10 + 22 + 10 + 12 + 10 + 12 = 83
Now that we have added those altogether, we can divide them by the amount of numbers there are. The amount of numbers there are comes to a total of 7. Therefore...
83 divided by 7 = 11.857
Answer Choice B. 11.9 is your correct answer.
Answer:
The number of Apples did Ravi have at first is 125 .
Step-by-step explanation:
Let the number of Apples did Ravi have at first = x
The Apples which is sold by Ravi =
of x
So, remainder now = x -
of x =
of x
The apples given to his friend =
of
x
I.e The apples given to his friend =
of x
Now, The remaining Apples did Ravi have = 50
∴ According to question
of x -
of x = 60
Or,
of x = 60
Or,
of x = 60
∴ x =
= 125
Hence The number of Apples did Ravi have at first is 125 . Answer
Answer:
x=11, y=13
Step-by-step explanation:
3x-2y=7
3x-2(x+2)=7 . - x + = - -2*+2=-4
3x-2x-4=7
1x-4=7
x=7+4
x=11
y=x+2
y=11+2
y=13
Answer:
0.06
Step-by-step explanation:

6 divide by 100= 0.06
Let Bea = x
Therefore Andrew = x + 2
Chris = x - 3
Andrew * Chris = 66
(x + 2)(x - 3) = 66 Remove the brackets.
x^2 + 2x - 3x - 6 = 66
x^2 - x - 6 = 66 Subtract 66 from both sides.
x^2 - x - 72 = 0
(x - 9)(x + 8) = 0
Find the possible values of Bea's age
x - 9 = 0
x = 9 That value works. She can be plus 9 years old.
x + 8 = 0
x = - 8. There's no way she can be - 8 years old
So Bea is 9.
