Answer:
131/156 or about 84%
5/14 or about 36%
Step-by-step explanation:
P(<6 classes) = number of males and females not taking 6 out of total males and females, which is 131/156 or about 84%
P(M,5) = 74/156 x 20/74 which reduces to 5/14
Answer:
.................. is answer
Answer:
The Answer is: The first number is 15 and the second one is 7.
Step-by-step explanation:
Let f = first number and s = second number
The difference between the two is 8:
f - s = 8
f = 8 + s
Twice the first number plus three times the second number is 51:
2f + 3s = 51
Substitute:
2(8 + s) + 3s = 51
16 + 2s + 3s = 51
16 + 5s = 51
5s = 51 - 16
5s = 35
s = 7, the second number
Find f:
f = 8 + 7 = 15, the first number
Proof:
f - s = 8
15 - 7 = 8
8 = 8

Answer:
Backpack: $5.50
Sweatshirt: $3.70
Soccer Ball: $3.72
Step-by-step explanation:
To find sale prices, you multiply the original price by the sale percentage. Once you have that answer, you subtract it from the original price.
For this problem, you have to multiply every number by .85 which is the decimal for of 85%.
.85*30=25.50
30-25.50=$5.50
.85*18=15.30
18-15.30=$3.70
.85*24.80=21.08
24.80-21.08=$3.72
Answer:
50th term is -338
Step-by-step explanation:
Common difference d = -2-5 = -7
first term is a1 = 5
50th term
a50 = a1 + (n -1)d
a50 = 5 -7(50-1)
a50 = 5 -7(49)
a50 = -338
Hope this will helpful.
