The determined value of mean µ is 1.3 and variance σ² is 0.81.

What is mean and variance?

A measurement of central dispersion is the mean and variance. The average of a group of numbers is known as the mean.
The variance is calculated as the square root of the variance.

We can determine how the data we are collecting for observation are dispersed and distributed by looking at central dispersion.

The table is attached as an image for reference.

Mean µ = ∑X P(X)

µ = 1.3

Variance (σ² ) = ∑ X² P(X)- (µ)²

= 2.5-(1.3)²

(σ² ) = 0.81

The determined value of mean µ is 1.3 and variance σ² is 0.81.

Sebastian wants to create a right triangle with side lengths 14 inches, 48 inches, and 5

allochka39001 [22]

Answer: Choice A

$\text{Yes, because } 14^2+48^2 \text{ is equal to } 50^2$

=======================================================

Explanation:

The pythagorean theorem is $a^2+b^2 = c^2$

The value of c is always the longest side, aka hypotenuse.

The order of 'a' and b doesn't matter.

So a = 14, b = 48, c = 50

We have $a^2+b^2 = 14^2+48^2 = 196+2304 = 2500$

We also have $c^2 = 50^2 = 2500$

Both sides result in 2500 which proves that $14^2+48^2 = 50^2$ is a true statement. Therefore, we do have a right triangle.

Can someone pls help me

Jlenok [28]

Answer:

16. 68

17. 97

18. 81

19. 96

20. 84.2

Step-by-step explanation:

A stem in a stem and leaf plot represents the tens place, and the leaf represents the ones place. The dat represented by the graph is the same exact as the numbers:

68, 75, 77, 79, 80, 82, 92, 96, 96, 97

Just by looking at the data, the minimum is 68 and the maximum is 97.

Next, to find the median, we can cross off the same amount of numbers from both sides until we are left with only two,:

68, 75, 77, 79, 80, 82, 92, 96, 96, 97

To find the median, we just find the mean of 80 and 82, which is 81.

The mode is the number that repeats the most, and that number is 96.

Lastly, to find the mean, we add up all the numbers and divide them by the amount of numbers:

(68 + 75 + 77 + 79 + 80 + 82 + 92 + 96 + 96 + 97) / 10

842 / 10

84.2 would be the mean.

Which change will triple the lateral surface area of a cone?

Fudgin [204]

The answer for this would be the second answer choice
This is because when the slant height is tripled, the overall lateral surface area is tripled
The best way to explain this would be through an example.

Say that the lateral height is 2 and the radius is 1. The lateral surface area is 6.28

Now, if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area

Therefore, the answer is choice 2

Hope this helped!! :D

How do i solve m/4+6=3

Ber [7]

$\frac{m}{4} + 6 = 3$
$\frac{m}{4} = 3 - 6$
$\frac{m}{4} = - 3$
$m = ( - 3)(4)$
so m=-12
