Write what you know in an equation: 27=30%•X. Divide 27 by .30 to get X alone: 27/.30=90. 27 is 30% of 90 :)
We are given the following equation:
Subtract both sides by 17
Take the positive/negative square root of both sides
This should be your answer. Let me know if you have any questions, thanks!
X% of y
x%=x/100
'of' means multiply
x% of y=x/100 times y so
48% of 8=48/100 times 8=384/100=3.84
3% of 119=3/100 times 119=357/100=3.57
26% of 280=26/100 times 280=7280/100=72.8
Answer:
C. 0.077
Step-by-step explanation:
Use binomial probability.
P = nCr pʳ qⁿ⁻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).
n = 10, r = 4, p = 0.64, q = 0.36.
P = ₁₀C₄ (0.64)⁴ (0.36)⁶
P = 210 (0.64)⁴ (0.36)⁶
P = 0.077
This is not correct because 6.5% of 25 is 1.63
