1,129.872
The 8 is in the tenth place. There is a 7 in the hundredths place. Since 7 is greater than or equal to 5, we round the 8 up. So it becomes a 9.
1129.9
Answer: 1129.9
This is how you solve the problem
Answer:
12 students from math club
Step-by-step explanation:
Number of vans = 2
Number of students in each van = 6
Number of students who went from math club to the soap box = ?
You can apply the following expression:
Total number of students=Number of students per van * Number of vans
Total number of students= 6 *2
= 12 students from math club....
Answer:
10.20% probability that a randomly chosen book is more than 20.2 mm thick
Step-by-step explanation:
Problems of normally distributed samples are solved using 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 problem, we have that:
250 sheets, each sheet has mean 0.08 mm and standard deviation 0.01 mm.
So for the book.

What is the probability that a randomly chosen book is more than 20.2 mm thick (not including the covers)
This is 1 subtracted by the pvalue of Z when X = 20.2. So



has a pvalue of 0.8980
1 - 0.8980 = 0.1020
10.20% probability that a randomly chosen book is more than 20.2 mm thick
