4/3 * pi * r^3
4/3 * 3.14 * 10^3
4/3 * 3.14 * 1000
4/3 * 3140 = 4186.66 rounds to 4187 in^3

Give one example of when you would make a frequency table to solve the problem
RideAnS [48]

Answer:

Consider a class in which there are 40 students .There is a Mathematics test of 50 marks .Two students were absent.The Duration of test was for one and half an hour.

So Marks of students according to their roll number are 12,8,4,20,25,36,2,29,35,39,5,48,43,37,38,29,17,15,15,25,31,32,26,28,27,24,2,15,34,,50,46,48,37,28,26,45,49,24.

So in this case it would be better to prepare frequency polygon by selecting a class interval.

Class interval = 0-5,5-10,10-15,15-20,20-25,25-30,30-35,35-40,40-45,45-50.

Or 0-10,10-20,20-30,30-40,40-50.

or you can make class interval by yourself.

How many real solutions exist for this system of equations?
Rom4ik [11]

Answer:

One

Step-by-step explanation:

Set each equations equal to each other

{x}^{2}  + 4 = 4x

{x}^{2}  - 4x + 4

Find the discrimant.

{ - 4 {}^{2} - 4(1)(4) } = 0

This means there is one real solution. Since the discramnt equal 0.

If the rejection region is +1.10, what will be your decision if the z computed value is 2.34
IRINA_888 [86]

The decision when the z value is within the rejection region is that we'll have to reject the null hypothesis.

<h3>What is a rejection region?</h3>

It should be noted that the rejection region is also known as the critical region. It is the set of values where the null hypothesis is rejected.

When the observed test statistic is in the rejection region, we'll have to reject the null hypothesis and then accept rte alternative hypothesis.
