148 - 4x = 112 (this means that for every question <em>x</em> four points were taken off from the total of 148 points and it equals to 112) 

Solve for x ... 
148 - 4x = 112
148 - 148 - 4x = 112 - 148
-4x = -36
x = 9

Can someone help me with this?
KATRIN_1 [288]

To find the equation of the line in slope-intercept form, y = mx + b, we can start by solving for the slope. The slope compares the vertical change (the rise) to the horizontal change (the run) when moving from one fixed point to another along the line.

The slope formula is:

m = (y2 - y1)/(x2 - x1)

We need to select 2 pairs of points from your given table.

Let (x1, y1) = (1, 8)

(x2, y2) = (2, 10)

Plug these values into the formula:

m = (y2 - y1)/(x2 - x1)

m = (10 — 8)/(2 — 1)

m = 2/1 or 2.

Therefore, the slope of the line is 2.

Next, we need to figure out what the y-intercept of the line is. The y-intercept is the point where the line crosses the y-axis. The y-intercept is also the value of y when x = 0.

Looking at your given table, you have an ordered pair, (0, 6) — this is the y-intercept. The y-coordinate (6) is the value of “b” in the slope-intercept form, y = mx + b.

Now that we have our slope (m) = 2, and y-intercept (b) = 6, we can write our equation as follows:

y = 2x + 6

an employee is selected from a staff of 10 to super- vise a certain project by selecting a tag at random from a box containing 1
USPshnik [31]

Probability that the number drawn is less than 4 is given by 0.3

<h3>What is probability?</h3>

The likelihood of an event happening is gauged by probability.

The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

The overall chance of every event in a sample space is 1.

Let random variable X represent the number of the drawn tag.

Since the simple space consists of 10 equally likely events

S = {1,2,3,4,5,6,7,8,9,10}

The formula for probability distribution is given by:

f(x) = { (1/10) for x = 1,2....10,    else 0 elsewhere

since, each number can equally likely occur, therefore

P(x) = 1/10 = 0.1

Probability that the number drawn is less than 4 is given by:

P(x<4) = P(1) + P(2) + P(3)

           = 0.1 + 0.1 + 0.1

           = 0.3
