By using the given table, we can see that the expected value is 20.97 AED.

<h3>How to find the expected value?</h3>

The expected value is given by the sum between the products between the value of each outcome and the probability of said outcome.

Then, by using the table, we can write the expected value as:

$12*0.8 + 18*0.15 + 20*0.31 + 22*0.08 + 24*0.15 + 25*0.23 = 20.97$

Then we can see that the correct option is C, the expected value is 20.97 AED.

2 x squared plus 5 x equals negative 2

Anna11 [10]

2x² + 5x = -2
or, 2x²+5x+2=0
or,2x²+4x+x+2=0
or,2x(x+2)+1(x+2)=0
or,(x+2)(2x+2)=0

Two values can be found:
(x+2)=0 (2x+1)=0
or,x= - 2 or,2x= -1
or, x= -1/2

Julia measured the high temperature in her town for one week. Using the chart below, find the mean absolute deviation for the hi

Alex

Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.

Find the slope of the line that passes through (10, 8) and (1, 9).

Snezhnost [94]

Answer:

m = 1/9

Step-by-step explanation:

Given:

x = 10

y = 8

x1 = 1

y1 = 9

Solution:

y - y1 = m ( x - x1 )

9 - 8 = m ( 10 - 1 )

1 = 9m

m = 1/9

Exponent rule : a^-x = 1/a^x

x^-9 * x^-2 =
1/x^9 * 1/x^2 = (when multiplying exponents with same base, add exponents)
1/x^(9 + 2) =
