Answer:

(-2, 1) is the only solution

Step-by-step explanation:

all other answers are not a solution.

3x - 2y = -8

6x + 7y = -5

substitute

(-2, 1)

3 * -2 - 2 * 1 = ?

-6 - 2 = -8

and

6 * -2 + 7 * 1 = ?

-12 + 7 = -5

all other subitutions do not make it a proper solution:

substitute

(5, -5)

3 * 5 - 2 * -5 = ?

15 - -10 = 25

25 $\neq$ -8

since the values have to be true for both equations this is not a solution, there is no need to do the second equation.

repeat this with the remaining

your answers are

(-2, 1) - yes

(-4, -2) - no

(7, 3) - no

(5, -5) - no

hope this helps:)

Answer: x = 1

x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i

x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i

That’s not enough information to say how long he could do it. He could go slower or faster than her but by how much if so. So it’s not enough info.

Venn diagram ( attached image )

alexandr402 [8]

Assessing the given Venn diagram and the data related to it, we can answer the required question:

Q1. How many people were surveyed = 86.

Q2. What is the probability that a customer chosen at random:

a) takes salt P(S) = 46/85.

b) takes both salt and vinegar P(S ∩ V) = 13/85.

c) takes salt or vinegar or both P(S ∪ V) = 66/85.

The number of people who take salt chips n(S) = 46.

The number of people who take vinegar chips n(V) = 33.

The number of people who takes both n(S ∩ V) = 13.

The number of people who take neither n((S ∪ V)') = 19.

Therefore, the total number of people surveyed n(U) = n(S) + n(V) - n(S ∩ V) + n((S ∪ V)') = 46 + 33 - 13 + 19 = 85.

The number of people who takes salt or vinegar or both n(S ∪ V) = n(U) - n((S ∪ V)') = 85 - 19 = 66.

The probability that a customer chosen at random takes salt P(S) = n(S)/n(U) = 46/85.

The probability that a customer chosen at random takes both salt and vinegar P(S ∩ V) = n(S ∩ V)/n(U) = 13/85.

The probability that a customer chosen at random takes salt or vinegar or both P(S ∪ V) = n(S ∪ V)/n(U) = 66/85.

The Wildcats in leopards are on evenly matched football teams when they play there is a .5 probability that the Wildcats win if

aliya0001 [1]

Answer:

P( x = 2) = 0.4

Or 40%

Step-by-step explanation:

Given that wildcat has 0.5 probability of winning if they play nine times

Probability = possible outcomes ÷ required outcome

The required outcome = 9

Probability = 0.5

Let calculate the possible outcomes

Possible outcomes = 0.5 × 9 = 4.5 games

the probability that the Wildcats win two of the games will be

P( x = 2) = 2/4.5 = 0.44

Or 44%
