Answer:

x<−2

Step-by-step explanation:

Let's solve your inequality step-by-step.

3<1−x

Step 1: Simplify both sides of the inequality.

3<−x+1

Step 2: Flip the equation.

−x+1>3

Step 3: Subtract 1 from both sides.

−x+1−1>3−1

−x>2

Step 4: Divide both sides by -1.

−x

−1

x<−2

Answer:

x<−2

Find the missing probability.

Westkost [7]

The value of the missing probability is:

P(A) = 1/5

So the correct option is D.

<h3>How to find the missing probability?</h3>

First, we know that:

P(A∩B) = probability that events A and B are true = 3/100

And we also know that:

P(B|A) = probability that event B is true given that event A is true = 3/20

Here we have the rule:

P(A∩B) = P(B|A)*P(A)

Replacing the first two:

3/100 = (3/20)*P(A)

Solving for P(A), we get:

(3/100)*(20/3) = 1/5 = P(A).

So we conclude that the correct option for the missing probability is the one in option D.

Juwan has a third quiz in math on Friday. His two previous quiz grades were 85 and 72. What must he make on the third quiz for h

VLD [36.1K]

Answer:

$x = 107$

Step-by-step explanation:

Given

$Scores = 85\ and\ 72$

$Average = 88$

Required

Determine the third score

Average is calculated using;

$Average = \frac{\sum x}{n}$

In this case:

$n = 3$

$Average = \frac{\sum x}{n}$

Let the third score be x; So:

$Average = \frac{85 + 72 + x}{3}$

Substitute 88 for Average

$88 = \frac{85 + 72 + x}{3}$

$88 = \frac{157 + x}{3}$

Multiply through by 3

$3 * 88 = \frac{157 + x}{3} * 3$

$264 = 157 + x$

$x = 264 - 157$

$x = 107$
