Answer:

x = 0

Step-by-step explanation:

First, let's translate this statement into an equation.

  • 5 times the sum of twice a number, x, and two means "5(2x + 2)"
  • is ten means "= 10
  • 5(2x + 2) = 10

<u>Solving</u>

Step 1: Simplify both sides.

  • (5)(2x)+(5)(2)=10
  • 10x+10=10

Step 2: Subtract 10 from both sides.

  • 10x+10-10=10-10
  • 10x=0

Step 3: Divide both sides by 10.

  • 10x/10=0/10
  • x=0

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Hello there the answer to your question would be 60. Since 150-(60%*150) = 150 - 60 *150 = (1-60%)*150 = (100%-60%) * 150= 40% * 150 = 40/100 * 150 = 40 * 150 ÷ 100 = 6000/100 = 60. Hope this helps you out, have a great day!

Translate each of the following research questions into appropriate H0 and Ha.
Mandarinka [93]

Answer:

a)

H_{0}: \mu = 62500\text{ dollars per year}\\H_A: \mu > 62500\text{ dollars per year}

b)

H_{0}: \mu = 2.6\text{ hours}\\H_A: \mu \neq 2.6\text{ hours}

Step-by-step explanation:

We have to build appropriate null and alternate hypothesis for the given scenarios.

a) Population mean, μ = $62,500 per year

The market research wants to find whether the mean household income of mall shoppers is higher than that of the general population.

H_{0}: \mu = 62500\text{ dollars per year}\\H_A: \mu > 62500\text{ dollars per year}

We would use one-tail(right) test to perform this hypothesis.

b) Population mean, μ = 2.6 hours

The company want to know the average time to respond to trouble calls is different or not.

H_{0}: \mu = 2.6\text{ hours}\\H_A: \mu \neq 2.6\text{ hours}

We would use two-tail test to perform this hypothesis.
