Determine whether the statement is true or false. If it is​ false, rewrite it as a true statement. As the size of a sample​ incr
Alchen [17]

Answer:

False

-As the size of the sample increases, the mean of the distribution of sample doesn't change.

Step-by-step explanation:

From central limit theorem, as the size of a sample size increases, the sample mean and sample standard deviation will be far much more closer in value to the population mean(μ) and standard deviation(σ).

Thus, as the size of the sample increases, there will be no changes to the mean of the distribution of the sample mean.

Pls i need answer with explanation asap.
Mandarinka [93]

Answer:

4 can be rewrite as 2•2, and that's the same as 2².

8 can be rewrite as 2•2•2, and that's the same as 2³

So we can rewrite the whole expression as:

2^x = (2²)⁸•(2³)⁴

2^x = 2¹⁶•2¹²

2^x = 2²⁸

So x = 28

A stuntman jumping off a 20-m-High building is modeled by the equation h=20-5t^2, where t is the same in seconds. A high-speed c
Alchen [17]

Answer: 1\leq t\leq \sqrt{2}


Step-by-step explanation:

1. You know that the high-speed camera is ready to film him between 15 meters and 10 meters above the ground.

2. The problem gives you the following equation:

h=20-5t^{2}

3. Therefore, you must calculate the time when h=15 and when h=10, as following:

h=15\\15=20-5t^{2}\\5t^{2}=5\\t=\sqrt{1}\\t=1  


h=10\\10=20-5t^{2}\\5t^{2}=10\\t=\sqrt{2}

4. Therefore, the answer is:

1\leq t\leq \sqrt{2}
