Answer:
0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 130 and a standard deviation of 11.
This means that
What is the probability that the next game Victoria bowls, her score will be between 123 and 130?
This is the p-value of Z when X = 130 subtracted by the p-value of Z when X = 123. So
X = 130
has a p-value of 0.5
X = 123
has a p-value of 0.2611
0.5 - 0.261 = 0.239
0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130
Answer:
Step-by-step explanation:
Lets calculate the fence first!
15*12=180
Mario needs to paint 180 ft^2
Turn this into a linear equation
250x=180
Divide by 250 on both sides:
x=0.72
So, Mario needs 0.72 Gal of paint to paint the fence!

Answer:
D
Step-by-step explanation:
a - 3 = 7 ( add 3 to both sides )
a - 3 + 3 = 7 + 3 , that is
a = 10
Yes.
30 x .30 = 9 cm is a 30% decrease
30-9= 21 cm
Answer:
1/15
Step-by-step explanation:
You can divide 3 and 45 by 3, so the simplified fraction wil be 1/15
