The number of ways that the company can choose four workers is 40920 ways.
<h3>How to calculate the number?</h3>
From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:
= 3 + 12 + 8 + 4
= 27 workers
It should be noted that combination will be used to choose the 4 workers. This is illustrated as
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
where n = 33
r = 4
ⁿCr = n! / ((n – r)! r!)
³³C₄ = 33! / (33 - 4)! 4!
= 33! / 29! 4!
= 33 × 32 × 31 × 30 / 4 × 3 × 2
= 40920 ways

Answer:
Richard's cumulative GPA = 2.5
Step-by-step explanation:
Richard's cumulative GPA for 3 semesters was 2.0 for 42 credits.
Average = 2
Total credits = 42
Average = sum of terms/total no of terms
2 = sum of terms/42
sum of terms = 84 ....(1)
His fourth semester GPA was 4.0 for 14 course units
Average = 4
Total credits = 14
sum of terms = 56 .....(2)
Average for 4 semesters,
Hence, Richard's cumulative GPA for all 4 semesters is 2.5.
Given that <span>Gary's unpaid credit card balance is $2543.32. His APR is 17.4% and he made one new transaction for $320. so his new balance can be solved by just adding the unpaid credit card balance and the new transaction he made.
new balance = </span><span> $ 2543.32 + $ 320
new balance = $ 2863.32</span>
48 cups of water
1. 4x4= 16 (number of cups in 1 gallon)
2. 16x3= 48 (cups in 1 gallon x the number of gallons she needs)
