Find mean of the data: 20,50,30,40,60,80. ​

Mathematics
1 answer:
Effectus [21]3 years ago
4 0

Step-by-step explanation:

Mean= The data points that add up, or, the sum of all data points, divided by the number of data points, will give you the answer,

So

20+50+30+40+60+80 would be

100+40+60+80 which is

200.

Since there are 6 numbers in the problem, we do

200/6

which will give us

33.33 etc. (33.3333333333 on and on forever)

Simplify completely 12 times x to the third power minus 4 times x to the 2nd power plus 8 times x all over negative 2 times x
lawyer [7]
(12x^3-4x^2+8x)/(-2x)  The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:

-6x^2+2x-4  and we can now also factor out -2

-2(3x^2-x+2)

Marissa claims that stacking 6 blocks with dimensions of One-half times 1 times 1 will give the same volume as stacking 9 blocks
quester [9]

Answer:

  • (A)Six of the one-half cubes would have a volume of 3 cubic units.
  • (D)Three of the one-third cubes will make 1 unit cube.
  • (E)Two of the one-half cubes will make 1 unit cube.
  • (F)Both stacks will have a volume of 3 cubic units.

Step-by-step explanation:

Marissa claims that stacking 6 blocks with dimensions of \frac{1}{2}X1X1  will give the same volume as stacking 9 blocks with dimensions of \frac{1}{3}X1X1  .

First, let us examine the volume of each of the blocks.

<u>For Block 1</u>

The dimensions are:   \frac{1}{2}X1X1

Volume of 1 block =  \frac{1}{2}X1X1= \frac{1}{2} $ cubic units

Volume of 6 blocks of dimension   =6* \frac{1}{2} =3$ cubic units

<u>For Block 2 </u>

The dimensions are:   \frac{1}{3}X1X1

Volume of 1 block =  \frac{1}{3}X1X1=\frac{1}{3} $ cubic units

Volume of 9 blocks of dimension =9*\frac{1}{3} =3$ cubic units  

The following statements out of Marissa's claim are true:

(A)Six of the one-half cubes would have a volume of 3 cubic units.

(D)Three of the one-third cubes will make 1 unit cube.

 3*\frac{1}{3} =1$ cubic units

(E)Two of the one-half cubes will make 1 unit cube.

 2*\frac{1}{2} =1$ cubic units

(F)Both stacks will have a volume of 3 cubic units.

Over 1,000 people try to climb Mt. Everest every year. Of those who try to climb Everest, 31 percent succeed. The probability th
Arada [10]

Answer:

A. P(success/age≥60) = 12.5%

B. Yes, the success is independent of age.

Step-by-step explanation:

Probability of success, given that a climber is at least 60 years old is calculated using conditional probability rule

P(A|B) = P(A n B)/P(B)

Probability of success given that a climber is at least 60 years old is given by

P(success|age≥60) = P(success n age ≥ 60)/P(age ≥ 60) = 0.005/0.04

= 0.125

P(success|age≥60) = 12.5%

B. The success is independent on age
