Find the median and mean of the data set below:
13,6,47,0

Answers

Mean 16.5 Median:9.5

Mean: add up all the numbers, then divide by how many numbers there are.

13+6+47+0=66
Since there are 4 numbers, divide it by 4 and you get 16.5 for your answer.

Median: arrange your numbers (from smallest to largest) then find the middle number

0,6,13,47

Since there are two numbers in the middle (6 and 13)
Add up those two numbers and divide it by 2.
6+13=19

19/2=9.5

Answer:

Median:9.5

Mean:16.5

Step-by-step explanation:

Median: Put them in order, find the middle, since there is two median we add them together, then divide them by 2 and there's your answer.

Mean: Add the numbers: 0+ 6+ 13+47= 66

Divide by how many numbers (there are 4 numbers): 66/ 4= 8

What is the value of x????

Answers

Answer:

x = 28

Step-by-step explanation:

The 2 radii of the circle form an isosceles triangle with base angles congruent, both 59°

The angle at the vertex O is then

180° - (59 + 59)° = 180° - 118° = 62°

The angle between the tangent and the radius is 90°

Then

x = 180 - (90 + 62) ← sum of angles in a triangle

x = 180 - 152 = 28

Answer: 102.5

Step-by-step explanation:

Area of triangle: 8*6=48, 48/2=24

Area of semicircle: 2pir^2=2pi(5)^2=157

Because its semi circle it is 157/2 which equals 78.5

Total area:24+78.5=102.5

Answer:

102.5

Step-by-step explanation:

Semi circle = 78.54 ≈ 78.5

Using formula A = πr²

Area triangle = 24

Using formula A = 1/2(bh)

Sum = 78.5 + 24 = 102.5

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years

Use the compound interest table to find each balance

Will give brainliest 5 stars and thanks

Answers

Answer:

[tex]\$13,107.96[/tex]

Step-by-step explanation:

Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.

Therefore, we can set up the following equation to find the new balance after 2 years:

[tex]\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}[/tex]

Juan went to the store to buy a plant for his mother, but forgot to ask which kind to get. Out of 30 plants, eighteen of them are a kind that his mother would want. If Juan chooses one randomly, what is the probability that he will choose a kind that his mother would want?

Answers

Answer:

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Step-by-step explanation:

Given:

Total number of plant in store = 30 plants

Number of plant kind Juan's mother want = 18

Find:

Probability [Randomly choose plant Juan's mother want]

Computation:

Probability of an event = Number of favorable outcome / Total number of outcomes

Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store

Probability [Randomly choose plant Juan's mother want] = 18 / 30

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Identify the volume of the hemisphere in terms of π. HELP ME PLEASE!!! THE RED IS THE ONE I GOT WRONG!

Answers

Answer:

6174π

Step-by-step explanation:

The equation for a whole sphere is 4/3 π(r)³

Given the diameter of 42, we can conclude that the radius would be 21

Next, we would plug in these variables and get 4/3 π(21)³

Simplify all of this down and you would get 12348π

Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π

Divide that by 2 and you get 6174π
