A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 30 minutes. What type of tail is this test using?

Answers

Answer 1

Answer:

Right tailed test

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu \le 30[/tex]

The alternative hypothesis is:

[tex]H_a: \mu > 30[/tex]

This is a right-tailed test since the alternative hypothesis is greater than 30

Suppose the level of significance is 0.05 and we are given a p-value less than  0.05.

Then, we reject the null hypothesis.

An album sells for $16.00 through an online music service. If the album is 10% off, and sales tax is 8%, what is the total price of the album including tax? A. $15.70 B. $15.68 C. $16.42 D. $15.55

Answers

Answer:  B. $15.68

Step-by-step explanation:

Given: Selling price of album = $16.00

Discount = 10% off

Sales tax = 8%

Discount = 10% of ( Selling price of album)

= 10% of $16

= 0.1 ($16)

= $1.6

Sales tax = 8% of ( Selling price of album)

= 8% of $16

= 0.08 ($16)

= $ 1.28

Total price of the album including tax = Selling price of album +Sales tax  - Discount

= $ 16 + $1.28 - $1.6

= $ 15.68

Hence, B. is the correct option.

Rochelle can run 800 meters in 5 minut
At that rate, how many meters can
Rochelle run in 9 minutes?

Answers

To find how much she can run in one minute we’re going to divide 800 by 5, to which we get 160.

She runs 160 meters in one minute.

We want to know how many meters she can run in 9 minutes.

160 * 9 = 1,440

She can run 1,440 meters in 9 minutes.

A space probe is launched from a platform that is just above 100 meters below sea level. The probe is expected to travel into deep space indefinitely. Write an equality showing the altitude of the probe after it is launched.

Answers

Answer:

x ≤ ∞

Step-by-step explanation:

Let x represent the height of the space probe above sea level in meters.

Initially, before launch, the space probe is launched from a platform that is just above 100 meters below sea level, hence:

x < -100 (the negative sign shows that it is below sea level).

After launch, The probe is expected to travel into deep space indefinitely. Therefore the height of the probe after it is launched is represented by the inequality:

x ≤ ∞

Answers

Divide John's goal amount by his hourly rate to find the answer.

$600 ÷ $7.50/hour = 80 hours.

So, John will have to work a total of 80 hours in order to earn $600.

Answer:

80

Step-by-step explanation:

If you divide 600 with 7.50 you will get 80.

That is simple!

Find the GCD (or HCF) of numerator and denominator

GCD of 600 and 750 is 150

Divide both the numerator and denominator by the GCD

600 ÷ 150

750 ÷ 150

Reduced fraction:

4

5

Therefore, 600/750 simplified to lowest terms is 4/5.

The sum of two consecutive numbers is 723. FInd the numbers.

Answers

Answer:

361 and 362

Step-by-step explanation:

a+b=723

b-a=1

b=1+a

a+1+a=723

2a+1=723

2a=723+1

2a=724

a=362

362+b=723

b=723-362

b=361

so b and a are 361 and 362 respectively

hence the consecutive numbers are 361 and 362
