## Answers

50% off because you’d get more of a discount

1225

Step-by-step explanation:

a) Already in step-by-step explanation

b) t(s) = - 1.91

c) At confidence interval 0.95 we have to reject the null hypothesis H₀

Step-by-step explanation:

We have:

Normal Distribution

Size sample < 30 n = 25

Independent samples

Therefore we can apply t-student analysis

1) Test hypothesis

Null hypothesis H₀ ⇒ μ₀ = 1503

Alternative hypothesis Hₐ ⇒ μ₀ < 1503 (from problem condition)

Now we have to compute t(s)

t(s) = [ ( μ - μ₀ )/(s/√n)

μ = sample mean

s = sandard deviation of sample

Then

t(s) = ( 1440 - 1503 ) / 165 / √25 ⇒ t(s) = - 63 * 5 / 165

t(s) = - 1.91

Now we look in t- student table for t(c) ( 24 degrees of fredom and α = 0,05 and find

t(c) = - 1.711 ( we must remember symmetry in t-studend curve)

So we compare t(s) with t(c)

t(s) = -1.91 t(c) = -1.711

t(s) is smaller than t(c) then our point is in the rejection zone we reject H₀

Answer with explanation:

Price of Product on the Website = $ 412.50

It is given that, product is offered at a discount of 25% on the website.

Let actual price of product on the store = $ x

Writing the above statement in terms of equation

→Price at store - Discount= Price at Website

[tex]x-\frac{25\times x}{100}=412.50\\\\ \frac{75 x}{100}=412.50\\\\x=\frac{41250}{75}\\\\x=550[/tex]

Price at store of that Product = $ 550

Solution: [tex]4\frac{3}{4}[/tex], 3.5, -15, 5

Not a solution: 129 and [tex]10\frac{2}{3}[/tex]

Step-by-step explanation:

20 ≥ 5 + 3x

3x + 5 ≤ 20

3x ≤ 20 - 5

3x ≤ 15

x ≤ 5

x must be LESS than or EQUAL to 5

Step-by-step explanation:

.35 x 3500 = 1250

The better deal would be website B.

Step-by-step explanation:

Website A is offering $50 off so you would so $250 - $50 = $200

Website B is offering 25% off so you would do (250 · 25)/100 = $62.50

The final price would be $250 - $62.50 = $187.50

So, overall with website A you'd be saving $50 dollars, and with website B you'd be saving $62.50 dollars, with website B you'd be saving more, so therefore the answer is website B.

Hope this helps you :)

Answer- I have no clue thank for the 50 points hshsbdbdhs

He makes $1,225 because 35% of $3,500 is $1,225
