katrin2010 [14]

Answer: $H_0:\mu=120$

$H_A:\mu\neq120$

Step-by-step explanation:

Let $\mu$ denotes the average braking distance for a population of small car.

Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.

i.e. $\mu=120$

Objective of test : Whether the statement made in the advertisement is false

i.e. $\mu\neq120$

Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.

So the null and the alternative hypotheses for the test will be:

$H_0:\mu=120$

$H_A:\mu\neq120$

Help please, what’s: 5x-7+2-2x=-26

svetoff [14.1K]

Answer:

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

5x−7+2−2x=−26

Step 1: Simplify both sides of the equation.

5x−7+2−2x=−26

5x+−7+2+−2x=−26

(5x+−2x)+(−7+2)=−26(Combine Like Terms)

3x+−5=−26

3x−5=−26

Step 2: Add 5 to both sides.

3x−5+5=−26+5

3x=−21

Step 3: Divide both sides by 3.

−21
