Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
Answer:
3
Step-by-step explanation:
9/3
The answer is A) -4/25 because when you multiply 8/15 and -3/10, you can simplify the expression to 4/5 times -1/5, which equals -4/25.
Answer:
Number of pineapples= 10
number of pears = 19
number of kiwis = 10 -2 = 8
Step-by-step explanation:
Cost of a pear = $ 0.50
Cost of a pineapple = $ 1.5
cost of a kiwi = $ 0.3
Let the pineapples = p
Number of pears = 9 + p
Number of kiwis = p - 2
The cost is
0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50
0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50
0.95 p = 9.6
p = 10
Answer: 2.36
Step-by-step explanation:
Using the μ=∑[x⋅P(X=x)
U will need to do
2/11 because you have 2 labeled 1
3/11 because you have 3 labeled 2
6/11 because you have 6 labeled 3
Then you will do:
1 x 2/11 = 0.18
2 x 3/11 = 0.5454 = 0.55
3 x 6/11 = 1.63
Then add them all together to find the μ
0.18 + 0.55 + 1.63 = 2.36
Hope that helps, plz put a good rating
