Answer:
11
Step-by-step explanation:
26=7(g-9)+12
14=7(g-9)
2=g-9
g=11
Answer:
0.07215 = 0.072 to 3 d.p.
Step-by-step explanation:
Central limit theorem explains that the sampling distribution obtained from this distribution will be approximately a normal distribution with
Mean = population mean
μₓ = μ = 9.8 minutes
Standard deviation of the distribution of sample means = σₓ = (σ/√n)
σ = 12 minutes
n = sample size = 30
σₓ = (12/√30) = 2.191
Probability that a random sample of 30 overtime periods would have a (sample) mean length of more than 13 minutes
Required probability = P(x > 13)
Since we've established that this distribution of sample means approximates a normal distribution
We first standardize 13 minutes.
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (13 - 9.8)/2.191 = 1.46
Required probability
P(x > 13) = P(z > 1.46)
We'll use data from the normal probability table for these probabilities
P(x > 13) = P(z > 1.46) = 1 - P(z ≤ 1.46)
= 1 - 0.92785 = 0.07215
Hope this Helps!!!
Answer:
The equation would be 1.5w + 187 = y.
Step-by-step explanation:
1.5 lbs per week
already 187
The variable would be 'w'
so 1.5w +187 = y
Mr.Moore will read 67 pages on Sunday. The pattern will continue each day by 12. So on Friday he will have 53 pages read. On Saturday he will have 60 Pages read. And on Sunday he will have 67 pages read. :)
Easy. it’s b because when it’s all added up 9 is the answer
