Answer:
-2.25
Step-by-step explanation:
We have that the mean (m) is equal to 500, the standard deviation (sd) 20
They ask us for P (x <455)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (455 - 500) / (20)
z = -2.25
Answer:
Step-by-step explanation:
There are 12 inches in one foot so the equivalent ones are:
1 to 12
This shows that there are 12 inches in one foot so is equivalent.
5 to 60
5/60 = 1/12
This is equivalent because it shows that 12 inches are required to make a foot.
9 to 108
9/108 = 1/12
This is also equivalent for the same reasons as above.
B) 312 divided by 75 is 4 with a remainder of 12
40 cents, divide 20 by .05
Answer:
1st option
