In short, you use 1, since any number is itself times 1, or whatever = whatever * 1

$\bf \cfrac{4}{\sqrt{50}}\iff \cfrac{4}{\sqrt{50}}\cdot 1\iff \cfrac{4}{\sqrt{50}}\cdot \cfrac{1}{1}\implies \cfrac{4}{\sqrt{50}}\cdot \cfrac{\sqrt{50}}{\sqrt{50}}
\\\\\\
\cfrac{4\sqrt{50}}{\sqrt{50^2}}\implies \cfrac{4\sqrt{50}}{50}$

Anna35 [415]

Use the formula for the conditional probability:

$Pr(A|B)=\dfrac{Pr(A\cap B)}{Pr B}.$

Consider such events

A - a senior takes the bus to school every day;

B - a senior has a driver’s license,

then

$Pr(A\cap B)=0.14$ ,

$Pr(B)=0.84$

and

$Pr(A|B)=\dfrac{0.14}{0.84} =\dfrac{1}{6}\approx 0.16666.$

In percent this is nearly 17%.

Answer: correct choice is B.

Answer:

The purpose of statistical inference is to provide information about the population based upon information contained in the sample.

Step-by-step explanation:

population based upon information contained in the sample

Step-by-step explanation:

Statistical inference is the process of using data analytics to deduce proprierties of an underlying probability distribution.

For example, if I want to know the percentage of Buffalo Bills fans that are from Canada. There is no way I can ask this question to every Bills fan(every Bills fan is the population). What I can do, for example, is go to a game and ask some of the fans there, that is, of a sample.

Answer:

x = 33

Step-by-step explanation:

2x + 1 + 4x - 19 = 180

you set to 180 assuming that that is a line and lines are = to 180 degrees

then solve for x

6x = 198

x = 33

A linear function graph has a dotted diagonal line passing through the x-axis at (3, 0), and the y-axis at (0, minus 2) In the f

Delicious77 [7]

The graph which best represents the new function is a linear function on a coordinate plane as shown in the image below.

<h3>How to determine the graph of the new function?</h3>

First of all, we would determine the slope of the linear function as follows:

$Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\\\\Slope, m = \frac{-2\;-\;0}{0\;-\;3}$

Slope, m = ⅔.

Multiplying by -4, the new slope is:

Slope = ⅔ × -4

Slope = -8/3 or 2.7.

For the equation of this line, we have:

y - y₁ = m(x - x₁)

y - 0 = -8/3(x - 3)

y - 0 = -8/3x + 8

y = -8/3x + 8

Decreasing the y-value by 1, we have:

y = -8/3x + 8

y = -8/3x + 8 - 1

y = -8/3x + 7

Therefore, we would have a linear function on a coordinate plane as shown in the image attached below.
