Answer:
The standard deviations is 
Step-by-step explanation:"
Given mean female height = 64 inches and standard devaiton = 3 inches and 69 inches tall is Sally.
We know the distance of a data point from:
Z =
=
So the standard deviations is
For A B and C, you just plug in the given number
A
B
C
And for D, you set the equation to 26 and solve for n
I had to use x instead of n, but for D n=7. :)
Answer:
<em>In the second group the individual members received a larger fraction of the prize money</em>
Step-by-step explanation:
<u>Division by Sharing</u>
A certain amount M can be evenly split among n parties by performing a division M/n.
The first group of six friends earned $45 and they split it evenly, i.e. the same amount goes to each member. Each of them received $45/6= $7.50 apiece.
The second group of four friends won the second-place prize of $35 and they split it evenly also. Each member received $35/4=$8.75.
By comparing both numbers, we see that 8.75 is a bigger fraction of 35 that 7.50 is of 45. Each member from the second-place price will receive more money than the first group.
We can conclude in the second group the individual members received a larger fraction of the prize money
Answer:
3) 14
Step-by-step explanation:
in the given equation replace the "g(x)" with the provided "20"
20=2(x-4) solve as usual
divide each side by 2
10=x-4
add 4 to each side
14=x
the value of x is 14
Answer:
n=21
Step-by-step explanation:
We must find n.
Remember PEMDAS. First we must do the Parentheses. Lets do distributive property by multiplying a number that is immediately outside the parentheses with each number inside the parentheses. Lets do this one side at a time.
First lets do 5(n - 7). We get 5n - 35
Now 2(n + 14) is 2n + 28
Okay...... now we have 
Now lets do OPPOSITES!!!! We must do the opposite of each thing to both sides.
The opposite of -35 is positive 35. Lets add 35 to both sides. We get:
Now lets do the opposite of 2n which is -2n
this is looking quite nice isnt it..........
The opposite of 3 times n is 3 DIVIDED BY n. So lets divide both sides by 3
amazing.......
