Mathematics

Andreyy893 years ago

Answer:

Mean: 22

Median: 21

Mode: No mode

Step-by-step explanation:

<u>Mean:</u>

The sum is the value of all the values divided by the number of values:

13+30+16+19+20+22+25+31/8  which is 22.

<u>Median:</u>

The median is the middle-most value of the data set when arranged from lowest to highest:

13, 16, 19, 20, 22, 25, 30, 31

Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.

<u>Mode:</u>

The mode is the most occurring value in the data set.

13, 16, 19, 20, 22, 25, 30, 31

Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.

Triangle ABC has perimeter 22 cm.
Vilka [71]

Answer: yes it is a right angle triangle

Step-by-step explanation:

a^2 + b^2 = c^2

8^2+ 5^2 = ?

64 + 25 = square root of 89

square root of 89 = 9.4

when we round 9.4 it is 9

so

22- (8+5) =

22 - 13 = 9

so our answer is correct

the half-life of strontium-90 is approximately 29 years. how much of a 500 g sample of strontium-90 will remain after 58 years​
Yuliya22 [10]

Answer:  125 g

<u>Step-by-step explanation:</u>

A = P_o\cdot e^{kt}\\\\\text{First, use the given information to find k:}\\\\\bullet A=\dfrac{1}{2}P_o\\\\\bullet k = unknown\\\\\bullet t=29\text{ years}\\\\\dfrac{1}{2}P_o=P_o\cdot e^{k(29)}\\\\\\\dfrac{1}{2}=e^{k(29)}\qquad divided\ both\ sides\ by\ P_o\\\\\\ln\bigg(\dfrac{1}{2}\bigg)=ln\bigg(e^{k(29)}\bigg)\qquad applied\ ln\ to\ both\ sides\\\\\\ln\bigg(\dfrac{1}{2}\bigg)=29k\qquad simplified-ln\ and\ e\ cancel\ out\\\\\\\dfrac{ln\bigg(\dfrac{1}{2}\bigg)}{29}=k\qquad divided\ 29\ from\ both\ sides\\\\\\-0.0239=k

\text{Now, use the following in the equation to solve for A:}\\\\\bullet A=unknown\\\bullet P_o=500\\\bullet k=-0.0239\\\bullet t=58\text{ years}\\\\A=500\cdot e^{(-0.0239)(58)}\\\\.\quad=500\cdot e^{-1.386}\\\\.\quad=125
