A holiday toy drive is putting together baskets for children they’re 84 toys and 56 books if each basket or see the same number
1 answer:
Answer:
28 baskets
Step-by-step explanation:
Given:
Total number of toys = 84
Total number of books = 56
To find the number of baskets than can be made by putting same number of toys and books in each basket.
Solution:
In order to find the number of baskets that can made by dividing 84 toys and 56 books equally in each basket, we will find the greatest common factor of the two numbers.
The factors of the numbers can be given as:
Thus, G.C.F.=
Thus, a total 28 baskets can be made, each basket having 3 toys and 2 books.

Answer:
84.13% probability a particular tire of this brand will last longer than 57,100 miles
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:
What is the probability a particular tire of this brand will last longer than 57,100 miles
This is 1 subtracted by the pvalue of Z when X = 57100. So
has a pvalue of 0.1587
1 - 0.1587 = 0.8413
84.13% probability a particular tire of this brand will last longer than 57,100 miles
