Answer:
10 nickels
Step-by-step explanation:
If she has a maximum of 66 cents and 12 are pennies than you need to see how many nickels go into 54 cents. You can only get 50 cents with nickels so you will have 10 nickels and 12 pennies for a total of 22 coins and 62 cents.
Answer:
y=1-7x
Step-by-step explanation:
7x+y=1
The first thing to do is get the y by its self. So u cancel the 7x out by-7x and bring it to the other side.
7x-7x = 0
Now all we have left is: y=1-7x
Hope it helps and is right.
Answer:
see explanation
Step-by-step explanation:
A = πr² ← r is the radius and r = 
d ← d is the diameter
Hence
π ( d)² = A, that is
= A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² = 
( take the square root of both sides )
d = 
A value of 24 is 2.5 standard deviations away from the mean
<h3>'How to determine the number of standard deviations away from the mean?</h3>
The given parameters about the distribution are:
Mean = 18
Standard deviation = 4
Value = 24
Let the number of standard deviations away from the mean be x.
The value of x is calculated using
Mean + Standard deviation * x = Value
Substitute the known values in the above equation
18 + 4 * x = 24
Subtract 18 from both sides of the equation
4 * x = 6
Divide both sides of the equation by 4
x = 1.5
Hence, a value of 24 is 2.5 standard deviations away from the mean
So, the complete parameters about the distribution are:
Mean = 18
Standard deviation = 4
Value = 24
24 is 2.5 standard deviations away from the mean
