Answer:
4 :-)))))))) have a wonderful day!
The answer is d because 42/45 as a percentage is 93
she needs 75 =10h=money per hour (so h=hour) +5= automatic tip
75=10h+5
75-5=10h+5-5
70=10h
70/10=10h/10
7=h
Answer:
B. 0.0028
Step-by-step explanation:
This is a binomial distribution. We could use a calculator to find the probability, or, since the sample size is large enough and both np and nq are larger than 10, we can approximate this as a normal distribution.
To do so, we first find the mean and standard deviation.
μ = np = (0.02) (1500) = 30
σ = √(npq) = √(0.02 × 0.98 × 1500) = 5.42
Now we find the z-score:
z = (x − μ) / σ
z = (45 − 30) / 5.42
z = 2.77
Finally, we use a z-score table to find the probability.
P(z > 2.77) = 1 − P(z < 2.77)
P(z > 2.77) = 1 − 0.9972
P(z > 2.77) = 0.0028
