Answer:

The histogram is presented in the second attached image to this solution.

Step-by-step explanation:

Histogram is a representation that uses bars to represent numerical distribution. It is similar to the bar chart but it is the histogram's area that corresponds to the frequency of the distribution instead of just the heights of the bars.

In constructing a histogram, we first divide the entire range of values into a series of intervals (called bins) and then count how many values fall into each interval, that is, the frequench of the variables in each range of values.

This question asks us to use 10 bins for this question.

The table of range of variables and frequencies used in the plotting of the histogram is presented in the first attached image to this solution and the histogram is presented in the second attached image to this solution.

Hope this Helps!!!

Given (x)=-x²+2x,determine<br> F'(x) using first principle
mote1985 [20]
Hello,
which principle?

f(x)=-x²+2x
==>f'(x)= -2x+2

You mean maybe this

\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}


f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x

\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}=\lim_{h \to 0}\frac{-2hx-h^2+2h}{h}=\lim_{h \to 0}\frac{-2x-h+2}{1}=-2x+2

(20 points) A statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s
Nimfa-mama [501]

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}

Simplify (x^3/8)^3/4
Viktor [21]

When an exponent is raised to another exponent, you can multiply the powers to simplify them.

3/8*3/4

<em>*Multiply numerators*</em>

3*3=9

<em>*Multiply denominators*</em>

8*4=32

x^9/32

Hope this helps!!
