Answer:
460 miles, 1 week
Step-by-step explanation:
249 per week + 0.25 per mile
180 per week + 0.4 per mile
after 460 miles in 1 week the cost will be the same
Answer: 13
Step-by-step explanation:
To get F(x), apply BODMAS; multiply first, then add, finally, subtract
F(x) = 2x4 + 3x3 – 2x2
= 8 + 9 - 4
17-4
f(×)= 13
A2+b2=c2
c2=10
x2+x2=100
2x=100
x=50
Divide by 2 to get 25.
Get square root of 25
Your answer is 5
Answer:
Explained below.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
A random sample of <em>n</em> = 658 items is sampled randomly from this population.
As the sample size is large, i.e. <em>n</em> = 658 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.
Compute the mean and standard deviation as follows:
(a)
Compute the probability that the sample proportion is greater than 0.63 as follows:
(b)
Compute the probability that the sample proportion is between 0.60 and 0.66 as follows:
(c)
Compute the probability that the sample proportion is greater than 0.592 as follows:
(d)
Compute the probability that the sample proportion is between 0.57 and 0.60 as follows:
(e)
Compute the probability that the sample proportion is less than 0.51 as follows:
