Adina read 60 out of 100 pages in a comic book. write the fraction of the pages she read in simplest form

2 answers:

8 0

60 ← Amount she read
---
100 ← Amount of pages there are

Find the lowest common factor.

In this case, we can say that it's 20. So, divide both the numerator and denominator by 20.

60 ÷ 20 3
--- = -------
100 ÷ 20 5

There is no other way to simplify this, so 3/5 is the most simplified version of 60/100.

Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).

WILL MARK BRAINLIEST IF ANSWERED CORRECTLY!

First question:

4(3x-5) + (2x -2)(4 + 3x-5)
Simplify -----> 12x - 20 + (2x-2)(3x-1)
Multiply the second part -----> 12x - 20 + 6x^2 -8x + 2
Combine like terms --------> 6x^2 + 4x - 18

Each side of the addition sign represents one of the rectangles above which is then added to get the area of the entire figure.

Second question:

The average is the summation of each data value divided by the number of data values. So it would be

(4 + 5 + 9)/ 3

Simplify ------> 18/3
Divide --------> 6
