Answer:
Answer is 904
Refer below.
Step-by-step explanation:
5650 total,
And 4:1 which adds up and make 5. So,
5x = 5650
x=5650/5
x=1130
As pichard part is 4:1 so his part is 4 overall the money so,
Richard got 4x = 4 × 1130 = 4520
4520 now dividing in 6:3:1
10a = 4520
A= 452
Wife amount is 3a = 3 ×452 = 1356
Son is 1a so its,
Son = 452
Minus= 1356 -452 = 904
Wife got 904 more than son
Answer:
QS = 15
Step-by-step explanation:
Thales
QS/QT = RS/PT
QS = QT·RS/PT
= 20×12/16
= 240/16
= 15
The final answer is the probability that the boat is overloaded because the mean weight of the 70 passengers is greater than 143lb is 1.0000.
A normal distribution is a continuous data distribution with a bell-shaped curve. The normally distributed random variable X has mean
and standard deviation
.
In addition, the standard normal distribution represents a normal curve with a mean of zero and a standard deviation of one.
The number of standard deviations an element deviates from the mean is indicated by a standardized Z-score.
What is the theorem of the central limit?
- If the sample size from the population is sufficiently large and has a finite variance, the mean of all samples taken will be approximately the same as the population mean. And the variance would be the population variance divided by the sample size. In addition, the sampling distribution would be roughly normal.
- The formula for sampling distribution of the sample mean is

- The formula for standard deviation of the sample mean is,

- Here,
is the population standard deviation and n is the sample size. - The formula for standard z-score is,

- From the given information,Population mean,
,Population standard deviation,
,Sample size, n=70 - Compute the probability that the boat is overloaded because the mean weight of the 70 passengers is greater than
.

As far as I can see you have gotten the majority of them right.
The only one I see, is the last number on the 4th row from the bottom.

------------
121 not 132.
I hope this Helps! :)
The correct answer is -3.6. Hope this helps!!
