Answer:

All real numbers

Step-by-step explanation:

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

−x2−6<0

Let's find the critical points of the inequality.

−x2−6=0

−x2−6+6=0+6(Add 6 to both sides)

−x2=6

−x2

−1

(Divide both sides by -1)

x2=−6

x=±√−6(Take square root)

Answer:

D. 73°

Step-by-step explanation:

The inside angles of a triangle always equal 180° so if we know that a right angle is already 90° we only need one more angle to know all of them:

1. 90° + 17° + ?° = 180

2. 90° + 17° = 107°

3. 180° - 107° = 73°

4. 90° + 17° + 73° = 180

Translating between Tables,

wel

Answer:

Table of values

$x \to y$

$0 \to -5$

$1 \to -2$

$2 \to 1$

$3 \to 4$

$4 \to 7$

$5 \to 10$

<em>See attachment for graph</em>

Step-by-step explanation:

Given

$y = 3x - 5$

Solving (a): Make a table

Considering the values of x from 0 to 5, we have:

When $x = 0$

$y = 3x - 5 \to 3 * 0 - 5 = -5$

When $x = 1$

$y = 3x - 5 \to 3 * 1 - 5 = -2$

When $x = 2$

$y = 3x - 5 \to 3 * 2 - 5 = 1$

When $x = 3$

$y = 3x - 5 \to 3 * 9 - 5 = 4$

When $x = 4$

$y = 3x - 5 \to 3 * 4 - 5 = 7$

When $x = 5$

$y = 3x - 5 \to 3 * 5 - 5 = 10$

So, we have:

$x \to y$

$0 \to -5$

$1 \to -2$

$2 \to 1$

$3 \to 4$

$4 \to 7$

$5 \to 10$

To the nearest degree, what is the mean (average) temperature of the data set below

balu736 [363]

Answer:

A. 19°

Step-by-step explanation:

To find the average of something, you add every number in the sequence and then divide it by how many numbers there are.

23 + 17 + 26 + 5 + 33 + 11 = 115

115 / 6 = 19.16666666666667

Round it down and your answer will be 19°.
