the mean of 16,18,x,12 and 15 calculate the value of x​

Answers

Answer 1

Answer:

29

Step-by-step explanation:

Mean = sum of datas/Sample size

Given the data  16,18,x,12 and 15

Sum =  16+18+x+12

Sum = 46+x

Mean = 15

Sample size = 5

Substitute

15 = 46+x/5

15 * 5 = 46+x

75 = 46 + x

x = 75-46

x = 29

Hence the value of x is 29

Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5

Answers

The median is 2
Median = Middle

First, arrange the numbers from lowest -> highest

This would be:
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.

If you are left with one number, that is your median!

If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)

In this case, you are left with one number, 2, so 2 is your median.
I hope this helped!

Answer:

2

Step-by-step explanation:

The median is the middle number when the numbers are lined up from least to greatest or greatest to least.

First, the numbers must be lined up from least to greatest.

0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Then, find the middle number.

The middle number is 2.

plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?

Answers

Answer:

[tex]Fence = 41.408ft[/tex]

Step-by-step explanation:

Given

[tex]d = 24ft[/tex]

Required

Determine the length of the wall

First, we calculate the circumference (C) of the semi-circle

[tex]C =\pi d[/tex]

[tex]C = 3.142 * 24[/tex]

[tex]C = 75.408[/tex]

The length of the fence is calculated by subtracting the diameter from the circumference:

[tex]Fence = C - d[/tex]

[tex]Fence = 75.408ft - 24ft[/tex]

[tex]Fence = 41.408ft[/tex]

Area of the cube (A) = 64 cm²

Now

The volume of the cube (V)

[tex]v \: = {a}^{ \frac{3}{2} } \\ v \: = 64 ^{ \frac{3}{2} } \\ v = 8 ^{ \frac{3 \times 2}{2} } \\ v \: = {8}^{3} \\ v = 512cm ^{3} [/tex]

Hope it will help :)❤

Answer:

512 cm³

Step-by-step explanation:

Let us understand the letters in the formula first. The rest is really quite simple.

V = volume

A = area

Let's substitute the known area in for A

V = 64^3/2

Solve for V

64^3/2 = 512

V = 512

Hence, the volume of the cube is 512 cm³

4) arc CB = 40 degrees

Step-by-step explanation:

If AB is tangent to the circle, then angle at A would be 90 degrees.

1)

Is 13^2 + 14.6^2 = 19.4^2?

169 + 213.16 = 376.36      No

2)

Is 8^2 + 6^2 = 10^2?

64 + 36 = 100      Yes

3)

arc WS = arc VU + arc TU = 113 degrees

arc ST = arc WV because their chords cross making a pair of vertical angles.

full circle = 360 degrees

360-113 - 113 = 134 degrees

134/2 = 67 degrees for arc ST

arc STU = 67 + 53 = 120 degrees

Angle UXS = 120 degrees

4) arc CB = arc FB =  40 degrees because their chords cross making a pair of vertical angles.

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?

Answers

Answer:

10

Step-by-step explanation:

Rate of drainage for pump A and B = [1 pool drained]/[6 hours]

Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]

Rate for pump B (newer pump) = [1 pool drained]/[t hours]

Thus, adding the rate of drainage of A and B,

1/t + 1/15 = 1/6

t=10
