A man bought a TV for £300. He had to pay a deposit of 15%. How much did he pay?

1 answer:

5 0

Most of the required information's are already given in the question.
Cost of the Television bought by the man = 300 pounds
Percentage of deposit that was made = 15%
Then
amount of deposit made by the man = (15/100) * 300 pound
= 15 * 3 pounds
= 45 pounds
So the man made a deposit of 45 pounds. I hope the procedure is simple enough for you to understand. You can always use this procedure for doing similar problems in future and you will require no additional help from anybody.

2 Points Simplify 4.2a+3.5b-3.1a.

Vlad1618 [11]

Answer: 1.1a +3.5b

Step-by-step explanation: You can combine the a’s because they are the same variable. 3.1a has a subtraction sign in front of it so when you combine it with 4.2a you’re actually subtract once 3.1 from 4.2 :)

In the Health ABC Study, 543 subjects owned a pet and 1977 subjects did not. Among the pet owners, there were 293 women; 975 of

True [87]

Answer:

The proportion of pet owners who were women is 0.540.

The proportion of non-pet owners who were women is 0.493.

Step-by-step explanation:

The data provided is summarized in the table below.

Pet Owners Non-Pet Owners TOTAL

Men 250 1002 1252

Women 293 975 1268

TOTAL 543 1977 2520

Denote the events as follows:

W = a subject is a women

P = a subject is a pet owner

The probability of an event, say E, is defined as the ration of the favorable outcomes of E to the the total number of outcomes of the experiment.

P (E) = n (E) ÷ N

Here,

n (E) = favorable outcome

N = total number of outcomes

(1)

The conditional probability of an event B given that another events A has already occurred is:

P (B | A) = n (A ∩ B) ÷ n (A)

Compute the probability of a pet owner being a women as follows:

P (W | P) = n (W ∩ P) ÷ n (P)

= 975 ÷ 1977

= 0.5396

≈ 0.540

Thus, the proportion of pet owners who were women is 0.540.

(2)

Compute the probability of a non-pet owner being a women as follows:

P (W | P') = n (W ∩ P') ÷ n (P')

= 293 ÷ 543

= 0.4932

≈ 0.493

Thus, the proportion of non-pet owners who were women is 0.493.

What is the greatest common factor of the numerator of ?

Annette [7]

The greatest common factor of the numerator and denominator of the rational expression is x - 4

<h3>How to determine the greatest common factor?</h3>

The fraction expression is given as:

$\frac{5x-20}{x^2-2x-8}$

Factorize the numerator and the denominator

$\frac{5x-20}{x^2-2x-8} = \frac{5(x-4)}{(x- 4)(x + 2)}$

Cancel out the common factor

$\frac{5x-20}{x^2-2x-8} = \frac{5}{(x + 2)}$

The common factor that was canceled out is x - 4

Hence, the greatest common factor of the numerator and denominator of the rational expression is x - 4
