If ab = 5 and a² + b² = 25, then (a + b)2 =?

bearhunter [10]

Answer:

35.

Step-by-step explanation:

a^2 + b^2 = (a + b)^2 - 2ab

Substituting the given values:

25 = (a + b)^2 - 2*5

(a + b)^2 = 25 + 10

(a + b)^2 = 35

Create a system of equations to solve

antiseptic1488 [7]

R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32

Subtract first equation from second equation.
2R=32 so R=16

Plug into first equation
16=2K so K=8

Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works

So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)

What is 7/1 dividend by 14/3

katrin2010 [14]

7/1 x 3/14 = 21/14 = 3/2 = 1 1/2

The answer is 1 1/12 or 1.5, but I recommend the fraction way since the problem was in fractions!

A long novel is opened to a random page; the probability that the page is numbered something between 21 and 31.

Harrizon [31]

Using the uniform distribution, considering that the novel has 435 pages, the probability that the page is numbered something between 21 and 31 is:

$p = \frac{10}{435}$

<h3>What is the uniform probability distribution?</h3>

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

Researching the problem on the internet, it is found that the novel has 435 pages, hence a = 0, b = 435, and the probability that the page is numbered something between 21 and 31 is given by:

$P(21 \leq X \leq 31) = \frac{31 - 21}{435 - 0} = \frac{10}{435}$
