Kalvin and 4 of his friends want to share 4 pounds of peanut butter equally. Write an expression to show what fraction of the peanut butter each friend should receive. Then write 2 equivalent fractions for this amount. (put a space and a comma to show the equivalent fractions

Each friend should receive pounds,  two equivalent fractions = ,  

Step-by-step explanation:

Given:

Kalvin and 4 of his friends want to share 4 pounds of peanut butter equally.

Question asked:

Write an expression to show what fraction of the peanut butter each friend should receive. Then write 2 equivalent fractions for this amount.

Solution:

Kalvin and 4 of his friends that means there are total 5 persons:

By unitary method:

5 friends receive amount of peanut butter in pound = 4

1 friend receives amount of peanut butter in pound =

Thus, each friend should receive   pound of the peanut butter.

Now, we will find two equivalent fractions for this amount:-

Multiplying both numerator and denominator by 2

Multiplying both numerator and denominator by 3

Thus, two equivalent fractions for this amount are ,  .

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
