The answer is:
 
 A Ramdom variable is a function that assigns a numerical value to every possible outcome in a sample space.
 
 It is a number that represents a result of an event or a random experiment. This variable does not depend on other factors and its values ​​are random, without a specific order. For example: when you roll a dice, the number that you get is a random variable, because in 6 attempts you may get 1,6,4,2,2,5 and then, in another 6 attempts, you may get 3,3, 6,2,1,6.

0.02x = 40 what is X step by step explanation
Korolek [52]

Answer:

2000

Step-by-step explanation:

In the equation, there is 0.02 attached to the x. This means multiplication. TO get rid of the 0.02, you need to do the opposite of multiplication. That is division.

Divide both sides by 0.02.

\frac{0.02x}{0.02} =\frac{40}{0.02}

x=2000

18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students,
yarga [219]

Answer:

112

Step-by-step explanation:

The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w

We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)

126 = (0.18)w, divide both sides by 0.18

126/(0.18) = w = 700

9th graders are 16% of the school or 16% of 700 students

c = (0.16) 700 = 112 students

What linear equation in slope intercept form does this graph represent?
guajiro [1.7K]

Answer: Hope this helps

y = 3/5x + 100

Slope: 3/5

Y-int: 100

Step-by-step explanation:

y = mx + b

<em>replace b with y-int</em>

y = mx + 100

<em>replace m with the slope which is 3/5</em>

y = 3/5x + 100

<em>How do you get slope?</em>

<em>Well I did rise/run with two points so I saw it ran 5 squares and rose only 3.</em>

<em>How do you get the y-int?</em>

<em>Well the y-int is the point where x is 0. So using the point (0,100), since x is 0, the y-int is 100.</em>
