<span>Multiplication with fractions is similar to multiplication with whole numbers in that you are often finding the product of groups of items. They are different in that you can multiply with fractions to find parts of an amount.</span>
Answer: Kim got 13 questions wrong.
Step-by-step explanation: First find how many questions were 75% of 52 questions since 3/4 is equal to 75%. Then subtract that amount (which is 39) from 52 and you get 13.
Answer:
0.1384
Step-by-step explanation:
Using binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Given n = 25, r = 4, p = 0.10, and q = 0.90:
P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴
P = 12650 (0.10)⁴ (0.90)²¹
P = 0.1384
1. S= squash
Z= zucchini
5s + 2z = 1.32
3s + 1z = 0.75. -2 ( 3s + 1z = 0.75)
5s + 2z = 1.32
-6s - 2z = -1.50
-s = -0.12
Squash = 0.12
5s + 2z = 1.32
5(.12) + 2z = 1.32
.60 + 2z = 1.32
2z = 1.32-.60
2z/2 =.72/2
Z= 0.36
