Select the graph for the solution of the open sentence. Click until the correct graph appears. 2|x| + 1 < 5

Paul [167]

Answer:

The correct answer is x < 2 or x > -2. The graph would be a line between -2 and 2 with an open circle on both.

Step-by-step explanation:

To solve, first solve the equation for the absolute value portion of the equation.

2|x| + 1 < 5

2|x| < 4

|x| < 2

Now since there is an absolute value around it, we have to complete it for the positive and negative versions.

x < 2 OR x > -2

Graph the linear equation by plotting three points. 2y=-3+2

Ksivusya [100]

Answer:

Step-by-step explanation:

Convert 2y=-3x+2 into y=mx+b form

$\frac{2y}{2} =\frac{-3x+2}{2}$

$y=\frac{-3x}{2} +1$

Y intercept is 1, slope is -3/2

The variance of the scores on a skill evaluation test is 143,641 with a mean of 1517 points. If 343 tests are sampled, what is t

Vlad1618 [11]

Answer:

The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

Step-by-step explanation:

We are given that

The variance of the scores on a skill evaluation test=143,641

Mean=1517 points

n=343

We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.

Standard deviation, $\sigma=\sqrt{143641}$

$P(|x-\mu|$

$=P(|Z|$

$=0.9216$

Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
