Answer:
<h3>The given statement " The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size " is <u>
True. </u></h3>
Step-by-step explanation:
Given statement is " The distribution of the sample mean, x overbar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size".
<h3>To check whether the given statement is true or not :</h3>
- The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size is <u>True. </u>
- The standard error of the mean is divided into half, then the sample size must be doubled.
∴ The given statement is true.

Answer: £30.20
We can say, 4kg of copper is mixed with 1kg of Zinc to make 5 kg of brass.
So to make 7 kg of brass we need to find out how much kg is copper and zinc mixed. Just increase one kg in both the weight, 5kg of copper and 2kg of zinc makes it 7kg of brass. (Technical thinking)
Now that we know the proportions of the metals so find out the costs of each kg of it.
Copper: 1 kg costs £5
5kg costs- 5*5 --> £25
Zince: 1 kg costs £3.20
2kg costs- 3.20 * 2 --> £5.20
Now add them, £5.20 + £25 --> £30.20
So, the cost of 7kg of brass is £30.20
Answer:
4 tacos
Step-by-step explanation:
according to the converse of triangle proportionality theorem, 7 beans is equivalent to 5 bananas, so if we took 2 away we would be left with 4 tacos, not apples because an apple a day keeps the doctor away and we are in a pandemic right now
answer:
22.5
step-by-step explanation:
- find the ratio of the other two segments
3 X 3 = 9
6 X 3 = 18
7.5 X 3 = 22.5
