Answer:

$x = 29$

Step-by-step explanation:

First we will expand the equation using the rule

$x(y - z) = xy - xz$

Thus,

$4(2x - 1) - 3 = 9(x - 4)$

is equal to

$8x - 4 - 3 = 9x - 36$

Simplify:

$8x - 7 = 9x - 36$

Add 36 to both sides:

$8x + 29 = 9x$

Therefore,

$x = 29$

What is the experimental probability that the next customer buys a red notebook 150 pages.

charle [14.2K]

Answer:

5/33

Step-by-step explanation:

The table with proper formatting is attached in the image below.

We have to calculate the experimental probability that the next customer buys a red notebook with 150 pages.

Total number of customers in the experiment = Sum of all the values in the given table = 396

Number of customers who bought red notebook with 150 pages = 60

Experimental probability = $\frac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}$

Number of favorable outcomes in the experiment were 60 and the total outcomes in the experiment were 396.

Therefore, the probability that next student buys a red notebook with 150 pages will be 60/396 = 5/33

Write an equation in slope-intercept form of the line shown.

tankabanditka [31]

Answer:

y = 3/4x - 2

Step-by-step explanation:

slope intercept form: y = mx + b

y-intercept(when x= 0) is given by b

slope is given by m

lets find the slope using the two given points, (4,1) and (8,4)

m = y2-y1 / x2-x1

m = 4 - 1 / 8 - 4

m = 3/4

Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).

1 = 3/4(4) - b

1 = 3 - b

b = -2

now you have m and b so you can finish writing your equation.

y = mx + b

y = 3/4x - 2
