Step-by-step explanation:
Answer:
10 red apples and 6 green apples
Step-by-step explanation:
first you multiply 5×2 to get 10 apples
then you multiply 3×2 to get 6 apples
Answer:
Multiply by 4
Step-by-step explanation:
The next number would be -320
1 1/2 * 3/4 =
Change 1 1/2 to an improper fraction = 3/2
3/2 * 3/4 = 6/4 * 3/4
6/4 * 3/4 = 18/4 = 4 2/4 = 4 1/2
The answer is 4 1/2.

Answer:
P(X < 80) = 0.89435.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

P(X < 80)
This is the pvalue of Z when X = 80. So



has a pvalue of 0.89435.
So
P(X < 80) = 0.89435.
