Answer: 45

Step-by-step explanation:

$\\$ To calculate the probability of the number of times a 1 we appear , we have

$\\$ number of times a 1 appeared / Total number of times the die is rolled.

$\\$ Let x represent the number of times a 1 is gotten

$\\$ And we have been given the probability of getting a 1 and also the total number of times the die is being rolled , substituting this inside the formula above , we have

$\\$ 0.3 = x / 150

$\\$ x = 150 x 0.3

$\\$ x = 45

Wilbur spends 2/3 of his income, share 1/12, and saves the rest. What part of his income does he save? Give the answer in simple

scoundrel [369]

Answer:

1/4 of his income.

Step-by-step explanation:

If Wilbur spends 2/3 of his income, 1/3 or 4/12 of it is left for other purposes (It is easier if everything has a common denominator of 12). And if he shares 1/12 of that remaining amount, there is 3/12 left. And when we simplify 3/12, we get 1/4.

Ken wants to buy some coffee mugs, m , that cost $5 each and some ground coffee, C, that costs $8 a pound. He has $25.

ValentinkaMS [17]

The inequality representation of the scenario is :

5m + 8c ≤ 25
m = 1 and c = 1

Number of mugs = m
Cost per mug = $5
Number of ground coffee = c
Cost per ground coffee = $8
Total amount to spend = $25

(Number of mug × cost per mug) + (Number of ground coffee × cost of ground coffee) ≤total amount to spend

Representing as an inequality : 5m + 8c ≤ 25

Combination of m and c that makes the inequality true :

Using trial by error :
m = 1 and c = 1
5(1) + 8(1) ≤ 25 ; 13 ≤ 25

Hence, m = 1 and c =1 are valid values for the expression.
