Answer:

second option

Step-by-step explanation:

the average is calculated as

average = \frac{sum}{count}

              = \frac{4x+5+7x-6-8x+2}{3}

              = \frac{3x+1}{3}

              = \frac{3x}{3} + \frac{1}{3}

              = x + \frac{1}{3}

Answer:

x + 1/3

Step-by-step explanation:

<u>It just basically the average of the three expressions</u>

<u>=> Remember to divide the expressions into 2 groups (the x group which contains x in it, and the numeral group which doesn't contains x)</u>

The x group: (4x + 7x + (-8x)) /3 = x

The numeral group: (5 +(-6) + 2) /3 = 1/3

So the answer must be x + 1/3, not x + 1

(I hope this is helpful)

How to solve this substitution​
Lena [83]
-5x+4y=11
substitute for x which is 5
(-5)(5)+4y=11

simplify :
4y-25=11

add 25 on both sides
4y-25=11
+25 +25
the 25 cancels out

so it would be 4y=36
and you divide both sides by 4

4/4 =36/4

which gives you (5,9)
x= 5 , y =9

You want to estimate the number of students in a junior high school who ride the school bus. which sample is unbiased?​
Vika [28.1K]

Answer:

Option B - 90 students at random during lunch

Step-by-step

An unbiased sample is defined as:

A sample is an unbiased sample if every individual or the element in the population has an equal chance of being selected.

Based on this, we can eliminate:

Option A) - It prevents non-eighth-graders of the school from being represented.

Option C) - Students in a hallway might take a particular class together/may be of the same grade. This gives them an unfair advantage.

Option D) - All students who are not in chorus are not represented in this set.

Given the following exponential function, identify whether the change
Len [333]

Step-by-step explanation:

We can determine whether the change represents exponential growth or decay by seeing whether the number being raised to x is between 0 and 1, or greater than 1.

In the equation y = 540(1.04)^x, y will increase every time that x increases, as we are multiplying by a number greater than 1 every time.

Hence, this exponential function represents exponential growth.

The percentage rate of increase for this function would be how much the y-value increases each time. Since we are multiplying by 1.04, each time the new value is 104% the original y-value. Hence, the percentage increase is 4%.
