4 0

Answer:

Radius = incenter → peprpendicular to one side of the triangle

Step-by-step explanation:

Bisect one of the angles
Bisect another angle
Where those two lines cross is the center of the inscribed circle, called the incenter
Construct a perpendicular from the center point to one side of the triangle
Place compass on the center point, adjust its length to where the perpendicular crosses the triangle, and draw your inscribed circle!

For what value or values of b is it true that |b| = -b

snow_tiger [21]

Answer:

b =0

Step-by-step explanation:

The only value where |b| = -b is when b=0

|0| = -0

0 = 0

Absolute value means non- negative

non-negative = negative

This is only true when we equal zero

Answer: B

Step-by-step explanation:

It is one sided test of R-squared being zero versus being greater than zero.

These are the steps of the test.

1. State the null and alternative hypothesis: ...

2. Compute the test statistic: ...

3. Find a (1 - 0.05)×100% confidence interval for the test statistic. ...

4. Decide whether to accept or reject the null hypothesis: 5.991 ∉ [0, 2.28], so reject H 0 .

5. Determine the p-value.

Which are correct representations of the inequality –3(2x – 5) < 5(2 – x)? Select two options.

Amiraneli [1.4K]

The correct representations of the given inequality are

–6x + 15 < 10 – 5x

and

A number line with an open circle at 5 and a bold line that starts at 5 and is pointing to the right. The correct options are the third and fourth options

<h3>Solving inequality</h3>

From the question, we are to solve the inequality

The given inequality is

–3(2x – 5) < 5(2 – x)

First, clear the brackets

–6x + 15 < 10 – 5x

NOTE: This is one of the correct representations of the inequality

Collect like terms

-6x + 5x < 10 - 15

-x < -5

Divide both sides by -1 and flip the sign

x > 5

Representing this on a number line, we get a number line with an open circle at 5 and a bold line that starts at 5 and is pointing to the right.

Hence, the correct representations of the given inequality are

–6x + 15 < 10 – 5x

and

A number line with an open circle at 5 and a bold line that starts at 5 and is pointing to the right. The correct options are the third and fourth options
