Compute a value for y that satisfies the equation below. <br><br> -3y - 12 = -4

lesantik [10]

First, add 12 to both sides of the equation,
-3y - 12 + 12 = -4 + 12
-3y = 8
Then, divide both the left hand and right hand sides of the equation by -3
(-3y) / -3 = 8/-3
The value of y is therefore,
y = -8/3

A jar contains black beads and green beads. Forty percent of the beads in the jar are green. A number generator simulates random

eduard

Answer:

The number generator is not fair. In most of the experiments, considerably less than 40% of the selected are green

Step-by-step explanation:

Given

$Pr(Green) = 40\%$

See attachment for plots

Required

Is the number generator fair or not

From the number line, we have the following outcomes:

$0 \to 1$

$1 \to 1$

$2 \to 7$

$3 \to 2$

$8 \to 1$

Divide each outcome by 12, to get the proportion of green in each trial

$0 \to 1$ $\to 8.33\%$

$1 \to 1$ $\to 8.33\%$

$2 \to 7$ $\to 58.33\%$

$3 \to 2$ $\to 16.33\%$

$8 \to 1$ $\to 8.33\%$

The above shows that the proportion of green in most of the trial is less than 40%

<em>Hence, the number generator is not fair.</em>
