Step-by-step explanation:

23, 27, 27, 28, 25, 26, 25, 29, 26, 27, 24, 26, 26, 24, 27, 25, 28, 25, 26, 25, 29, 26, 27, 24, 26

Arranging in ascending order;

23, 24, 24, 24, 25, 25, 25, 25, 25, 26, 26, 26, 26, 26, 26, 26, 27, 27, 27, 27, 27, 28, 28, 29, 29

Mean = Sum of mileage / Number of millage

Number of mileage = 25

Sum of mileage = 651

Mean = 651 / 25 = 26.04

Median = Middle Number (13th number) = 26

Mode (Highest occurring) = 26 (7 times)

A person draws a card from a hat. Each card is one color with the following probabilities of being drawn: 1/10 for red, 1/5 for

Kay [80]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

We are given that a card is drawn from a hat.

Probability that a red card is drawn, P(red) = $\frac{1}{10}$

Probability that a blue card is drawn, P(blue) = $\frac{1}{5}$

Probability that a black card is drawn, P(black) = $\frac{1}{20}$

Probability that a pink card is drawn, P(pink) = $\frac{1}{5}$

All these events are mutually exclusive i.e. they do not have anything in common.

For any two events A and B which are mutually exclusive, with probability P(A) and P(B), the probability that any one of the two events occur:

$P(A\cup B) = P(A) + P(B)$

Here event A can be thought of as drawing a blue card and

event B can be thought of as drawing a black card

So, P(blue or black) = P(blue) + P(black)

$\Rightarrow \dfrac{1}{5}+\dfrac{1}{20}\\\Rightarrow \dfrac{4+1}{20}\\\Rightarrow \dfrac{5}{20}\\\Rightarrow \dfrac{1}{4}$

So, the probability that a blue or black card is drawn from the hat:

$\dfrac{1}{4}$

Write the sentence as an equation.<br> the sum of 236 and f is equal to 182

frosja888 [35]

Answer:

236+f=182

Step-by-step explanation:

To start with, we know 236 and f are being added together because of the word "sum" in the sentence. We also know they will equal 182, so this is the answer.

PLEASE ANSWER !!

ANEK [815]

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

$y = mx+b$

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

$y = mx+b$

$-10=\frac{5}{2}\left(-2\right)+b$

$-\frac{5}{2}\cdot \:2+b=-10$

$-5+b=-10$

$-5+b+5=-10+5$

$b=-5$

And the equation of the line in the slope-intercept form will be:

$y = mx+b$

putting b = -5 and slope = m = 5/2

$y = mx+b$

$y=\frac{5}{2}x+\left(-5\right)$

$y=\frac{5}{2}x-5$

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

$0=\frac{5}{2}x-5$

$\frac{5}{2}x-5=0$

$\frac{5}{2}x=5$

$5x=10$

$x=2$

Therefore, the zeros of the function will be:

x = 2
