what is 64% of 75 tile Also include an explanation, I don't really understand what my teacher explained to my class

Answers

You can find what 1% is of 75 by dividing 75 by 100 in a calculator, which is .75
Next you can do .75*64, which is 48.
We have an equation: ?/75= 64/100

Cross multiply:
100*?= 75*64
⇒ ?= 75*64/100= 48

64% of 75 is 48~

The ratio of blue chairs to red chairs in Ms.Vicker's class is 2 to 5. Which of the following cannot represent the total number of chairs in Ms. Vicker's class? A:14
B:20
C:28
D:35

Answers

After checking all the options for the ratio, the value which cannot represent the total number of chairs is 20. Hence, option B is correct.

What is ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.

As per the given information in the question,

Let's check for the first option,

2x + 5x = 14

7x = 14

x = 2

Which means that

2(2):5(2) = 14

4:10 = 14, it is correct

Let's check for the second option,

2x + 5x = 20

7x = 20

x = 2.85

2(2.85):5(2.85) ≠ 20, thus this one is incorrect.

Let's check for the third one,

2x + 5x = 28

7x =28

x =4

2(4):5(4) = 28, it is correct.

Similarly, D is also correct

The common ratio is -2.5

Next 3 terms after 50 are -125, 312.5, -781.25

What is a geometric sequence and common ratio?

A sequence ( increasing or decreasing)  having a pattern that the next term is found by multiplying the previous term with a constant term called common ratio, is called a geometric sequence. Common ratio can be positive or negative.

  • Common ratio can be found by dividing a term by its previous term.
How to find the common ratio of the given geometric sequence?

The given sequence is 8, -20, 50......

The common ratio is  

How to find the next terms of the given geometric sequence?
  • In a geometric sequence, a term multiplied by the common ratio gives ithe next term.

Next term after 50 = {50 x (-2.5)} = -125

Next term after -125 = {(-125) x (-2.5)} = 312.5

Next term after 312.5 = {312.5 x (-2.5)} = -781.25

  • Next 3 terms after 50 are -125, 312.5, -781.25

Answer:

see explanation

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = = = .....

r = = = - 2.5

Multiplying each term by - 2.5 gives the next term

50 × - 2.5 = - 125

- 125 × - 2.5 = 312.5

312.5 × - 2.5 = - 781.25

The next 3 terms in the sequence are - 125, 312.5, - 781.25

The average height of students at UH from an SRS of 12 students gave a standard deviation of 3.1 feet. Construct a 95% confidence interval for the standard deviation of the height of students at UH. Assume normality for the data.

Answers

Answer:

Step-by-step explanation:

The confidence interval for the standard deviation is given by :-

Given : n= 12 ; s= 3.1

Significance level :

Using Chi-square distribution table ,

Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by :-

A 95% confidence interval for the standard deviation of the height of students at UH (2.20, 5.26)

Calculations and Parameters:

The confidence interval is given by:


Given

  • n= 12 ;
  • s= 3.1

Significance level : =1 - 0.95

= 0.05.

Using Chi-square distribution table ,

Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by:-

(2.20, 5.26)
