Graph (b) represents the data provided that option (b) would be the correct choice.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}$

We have the data shown in the table.

The equation of the line M = 3n represents the data provided,

After plotting all the points on the coordinate plane.

We will get a graph that represents the data.

Thus, graph (b) represents the data provided the option (b) would be the correct choice.

The weight of an object on the moon varies directly as its weight on earth. A person who weights 150.94lb on earth weighs 25.66l

Veronika [31]

109.93 lbs

since the quantities vary directly, then

w(moon) = kw(earth ) ← ( k is the constant of variation )

to find k use the given condition

k = w( moon ) / w( earth ) = $\frac{25.66}{150.94}$

given w(earth) = 218.24

w(moon) = $\frac{25.66(218.24)}{150.94}$ = 109.93

I NEED HELP ASAP!!!!

dedylja [7]

Answer:

B) 8

Step-by-step explanation:

Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.

If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.

A random variable is uniformly distributed over the interval [-4, 6]. find the mean, variance, and standard deviation of .

Lyrx [107]

The mean, variance, and standard deviation are 1, 8,33 and 2.89

<h3>How to find the mean, variance, and standard deviation?</h3>

The distribution is given as:

[a, b] = [-4, 6]

The mean is calculated as;

Mean = (a + b)/2

So, we have

Mean = (-4 + 6)/2

Evaluate

Mean = 1

The variance is calculated as;

Var = (b - a)^2/12

So, we have

Var = (6 + 4)^2/12

Evaluate

Var = 8.33

The standard deviation is calculated as;

SD= sqrt(Var)

So, we have

SD = sqrt(8.33)

Evaluate

SD = 2.89

Hence, the mean, variance, and standard deviation are 1, 8,33 and 2.89
