Please answer it correctly and I'll mark it​
kirza4 [7]

Answer:

Step-by-step explanation:

1) a very poor question indeed. It has at least two possible solutions

c = 3x + 2                                     or     c = 3(x + 2)

when x = 2

c = 3(2) + 2 = 8                           or      c = 3(2 + 2) = 12                  

when x = 5

c = 3(5) + 2 = 17                          or       c = 3(5 + 2) = 21

2)

y = x + 2

when x = 2

y = 2 + 2 = 4

when x = 5

y = 5 + 2 = 7

Answer:

C) 20.97 AED

Step-by-step explanation:

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as \displaystyle E(X)=\mu=\sum xP(x).

Here, x represents values of the random variable X, P(x) represents the corresponding probability, and symbol \displaystyle \sum represents the sum of all products xP(x). Here we use the symbol \mu for the mean because it is a parameter. It represents the mean of a population.

In this case, the expected value of the ticket is \displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97

This means that Ahmad can expect to win 20.97 AED for the ticket.

A line passes through (2,-1) and (4,5). What answer is the equation of the line? -3x+5y=-13
Sliva [168]

The equation of the line passes through (2, -1) and (4, 5) is -3x + y = - 7 So, option 2 is correct.

<u>Solution:</u>

Given, two points are (2, -1) and (4, 5)

We have to find that a line that passes through the given two points.

First let us find the slope of the line that passes through given two points.

So, slope of line "m" is given as:

\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text { where, }\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) \text { are two points on line. }

So slope of our line = \frac{5-(-1)}{4-2}=\frac{5+1}{2}=3

Now, let us find the line equation using point slope form:

y-y_{1}=m\left(x-x_{1}\right) \text { where } m \text { is slope and }\left(x_{1}, y_{1}\right) \text { is point on the line. }

Then equation of line is,

y – 5 = 3(x – 4)  

y – 5 = 3x – 12  

-3x + y = 5 – 12  

-3x + y = -7

Hence, the line equation is -3x + y = - 7 so, option 2 is correct.
