Answer:
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:
Use the information on the right to find the z-score of a 2,500 g baby.
This is Z when X = 2500. So
Volume of a pyramid =1/3B*H
B is Area of base here base is triangle
so Area of a triangle=1/2*b*h
=1/2*5*12
=30 cm^2
Volume=1/3*30*H
90=1/3*30*h
90*3/30=h
(volume is given)
h=9 cm
Answer:
Step-by-step explanation:
First we multiply the numbers, because you can't divide fractions. We switch the placement of 8 and 1 and then we multiply (The one multiplied by everything is just the same so we can ignore it)
× =
Then we convert it to a mixed number by using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
Therefore, we can find out that is the answer.
