Answer:

(p - q) (a - 1)

Step-by-step explanation:

To change q - p as p - q we pull out -1So q - p becomes

-1(p - q)a(p–q)+q–p

a(p–q) -1(p - q)

p -q is in common so we factor out

p-q(p - q) (a - 1)

Q 5 a) calculate the value of d

Leya [2.2K]

Answer:

This is not possible.

Step-by-step explanation:

6 m = 600 cm

A triangle with a 600 cm leg and a 10 cm hypotenuse is impossible

If the 6 m should have been 6 cm, then:

Using the Pythagorean theorem:

base² = 10² - 6² = 100 - 36 = 64

base = √64 = 8

d² = 8² + 15² = 64 + 225 = 289

d = √289 = 17 cm , not meters

The amount of time it takes Victoria to solve crossword puzzles can be modeled by a continuous and uniformly distributed random

givi [52]

Answer:

80% probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X greater than x is given by the following formula.

$P(X > x) = 1 - \frac{x - a}{b-a}$

Uniformly distributed random time between 4 minutes and 12 minutes.

This means that $a = 4, b = 12$

What is the probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes?

Already working for 7 minutes, so a is updated to 7.

$P(X > 8) = 1 - \frac{8 - 7}{12 - 7} = 0.8$

80% probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes
