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
Diagonals must be congruent in a rectangle.
Answer:
5 crayons
Step-by-step explanation:
A standard pack of crayons is 24, so I put b = 24.
24 + 6 - (x) = 25
30 - (x) = 25
- 30 -30
- (x) = -5
÷ -1 ÷ -1
(x) = 5
I really hope this helps!
This is an observational study and the conclusion of the researcher is not justified.
<h3>Controlled experiment</h3>
A controlled experiment is such that all the other factors in the experiment are kept the same except the variable that is being studied. This study is not a controlled experiment is not a controlled experiment because other factors that could affect the study were not carefully controlled.
This is an observational study. The conclusion of the researcher is not justified because other factors such as diet which could affect the blood pressure were not taken into account.
