Solve the absolute value equation.

First subtract 5 from both sides.

|x|+5=18

|x|=13

If the absolute value of x is 13 that x equals 13 and -13. Absolute value means distance from 0.

x=13,-13

Part A. Express the original claim in symbolic form.

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.

Therefore, the original claim in symbolic form is:

ANSWER:

$\mu=68.9\text{ bpm}$

Part B. Identify the null and alternative hypotheses.

$\begin{gathered} H_0\colon\text{ }\mu=68.9\text{ bpm} \\ H_1\colon\mu\ne68.9\text{ bpm} \end{gathered}$ $\begin{gathered} H_0\text{ or the null hypothesis will be based to our claim. We will test if the mean pulse} \\ \text{rate of an adult male is equal to 68.9 bpm.} \\ H_1\text{ or the alternative hypothesis is the one that contradicts the null hypothesis. That is } \\ \text{why our H}_a\text{ has the sign of not equal to (}\ne). \end{gathered}$

Answer:

116 miles

Step-by-step explanation:

Given

$(x_1,y_1) = (-41,3)$ --- Camp 1

$(x_2,y_2) = (75,3)$ --- Camp 2

Required

The distance between both camps

This is calculated using:

$d^2 = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}$

$d^2 = \sqrt{(-41-75)^2 + (3-3)^2}$

$d^2 = \sqrt{(-116)^2 + (0)^2}$

$d^2 = \sqrt{116^2}$

$d = 116$

The distance is 116 miles

The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, h

Leno4ka [110]

Answer: 24

Step-by-step explanation:

Let the number of defeats be represented by x.

Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:

= x + 4

We then add the number of victories and losses together and equate them to 44. This will be:

x + x + 4 = 44

2x + 4 = 44

2x = 44 - 4

2x = 40

x = 40/2

x = 20

Therefore number of victories will be:

= x + 4

= 20 + 4

= 24

PLEASE ANSWER CORRECTLY <3 I WILL GIVE BRAINLIEST THANKS IN ADVANCE!

Vikentia [17]

Answer:

1: 130

2: 70

Step-by-step explanation:

Supplementary angles add up to equal 180

So to find the measure of the missing angles, we subtract the measure of the known angles from 180

For #1

∠B = 180 - 50

180 - 50 = 130

Hence ∠B = 130

For#2

∠D = 180 - 110

180 - 110 = 70

Hence, ∠D = 70
