1. No correlation

Those things don't really relate to each other.

2. Positive correlation

The higher the amount you drive your car, the more you'll have to pay for gas.

3. Negative correlation

More people = less soda.

The marks price of an article is 4500.after allowing some percent of and levying 10% VAT it is sold at 4400, find the discount p
Mars2501 [29]

The discount percent for the given transaction is calculated as; 6.11%

<h3>What is the percentage Discount?</h3>

We are given;

Mark Price; M.P = 4500

Now, formula for discount amount is;

Discount amount = %Discount * M.P

Discount amount = x% * 4500 = 45x

Also;

Selling price is;

S.P = M.P - Discount Amount

S.P = 4500 - 45x

VAT = Vat% * S.P

VAT = (10%*4500) - 45x

VAT = 450 - 45x

S.P with VAT = S.P + VAT Amount = 4500 - 45x + 450 - 45x = 4950 - 90x

Thus;

4950 - 90x = 4400

Solving for x gives;

x = 6.11%

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t
NeX [460]

Answer:

0.09

Step-by-step explanation:

Given that 50% of this population prefers the color green.

Let p the probability that one person selected from the population prefer the green color of the car. So,

p=0.05

There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.

By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is

P(r)=\binom{n}{r}p^{r}{(1-p)}^{n-r}\cdots(i)

Here, 15 buyers are randomly selected, so, n= 15 and

r= \frac1 3 \times 15=5

So, by using equation (i), the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is

P(r=5)=\binom{15}{5}(0.5)^{5}{(1-0.5)}^{15-5}

=\binom{15}{5}(0.5)^{5}{0.5}^{10}

=\binom{15}{5}(0.5)^{15}

=0.0916

Hence, the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is 0.09.

Tess created a Pythagorean triple of (24, 32, 40) by multiplying the known Pythagorean triple 3, 4, and 5 by 8. Is Tess correct?
pentagon [3]

Answer:

(24, 32, 40) is a Pythagorean triplet.

Option A) Yes, as long as each number in the Pythagorean triple is multiplied by the same whole number.                

Step-by-step explanation:

We are given the following in the question:

Pythagorean triplet: (3,4,5)

New Pythagorean triplet obtained = (24, 32, 40)

Pythagoras theorem:

For a right angles triangle the sum of square of sides of triangle is equal to the square of hypotenuse of triangle.

Verification:

24^2 + 32^2\\=576 + 1024\\=1600\\=40^2

Yes, Tessa is correct.

(24, 32, 40) is a Pythagorean triplet.

Pythagorean triple be created using multiplies of a known Pythagorean triple

Option A) Yes, as long as each number in the Pythagorean triple is multiplied by the same whole number.

2. Explain how to calculate 8% of 350 by first calculating 1% of 350.
V125BC [204]

Answer:

28

Step-by-step explanation:

So 1% of 350 would be 3.5 because 350 divided by 100 is 3.5. You then get 3.5 and multiply it 8 times, which would be 28. (You multiply it 8 times because 8% is 8 times 1%.)
