Answer:

\frac{15}{64} of the pie

Step-by-step explanation:

Whole numbers refer to a collection of natural numbers together with 0.

Fraction refers to part of a whole.

Part of an apple pie left from a dinner = \frac{3}{8}

Part of an apple eaten by Victor tomorrow is equal to  \frac{5}{8} of the pie that was left

So,

Part of an apple eaten by Victor tomorrow = \frac{5}{8}(\frac{3}{8})=\frac{15}{64} of the pie

Richard & Tanjeev share a lottery win of £5650 in the ratio 4 : 1. Richard then shares his part between himself, his wife &a
lidiya [134]

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

a boat capsized and sank in the lake. based on an assumption of a mean weight of 143 lb, the boat was rated to carry 70 passenge
Alenkinab [10]

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 $\mu$ and standard deviation $\sigma$.

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 $\mu_{\bar{x}}=\mu$
  • The formula for standard deviation of the sample mean is,\sigma_{\bar{x}}=\frac{\sigma}{\sqrt{n}}
  • Here, $\sigma$ is the population standard deviation and n is the sample size.
  • The formula for standard z-score is,

z=\frac{\bar{x}-\mu_{x}}{\frac{\sigma}{\sqrt{n}}}

  • From the given information,Population mean, $\mu=171$,Population standard deviation, $\sigma=37.7$,Sample size, n=70
  • Compute the probability that the boat is overloaded because the mean weight of the 70 passengers is greater than $143l \mathrm{~b}$.

$$\begin{aligned}P(\bar{X} > 143) &=P\left(\frac{\bar{X}-\mu}{\sigma / \sqrt{n}} > \frac{143-171}{37.7 / \sqrt{70}}\right) \\&=P(Z > -6.21) \\&=1-P(Z < -6.21) \text { (Use the Excel function NORMSDIST(-6.21)) } \\&=1-0.0000 \\&=1.0000\end{aligned}$$
