Answer:

You would have to look at the explanation since there are multiple

Step-by-step explanation:

-7x + 1 would have to be greater than or equal to 15.

-7(2) + 1 = 15 so you would mark a filled in dot at 2 and point an arrow going to the right.

6x + 3 must be greater than or equal to -21.

6(-4) + 3 would equal -21 so you would mark a filled in dot at negative 4 with an arrow going to the right.

Which inequality represents all the values of x for which the product below is defined?

scoundrel [369]

Answer:

x≥0 is correct inequality.

D is correct.

Step-by-step explanation:

We are given a function $f(x)=x\sqrt{x}-4\sqrt{x}+1$

We need to find x where function is defined.

As we know negative inside the root not defined.

Inside the root value must be greater than equal to 0.

Here we have inside the root is x.

Therefore, x must be greater than equal to 0.

Inequality: x≥0

Please see attached graph for more clarification.

Hence, x≥0 is correct inequality.

Assume that the last two digits on a car number plate are equally likely to be any of the one hundred outcomes {00, 01, 02, ....

gizmo_the_mogwai [7]

Answer:

1) Probability that Peter wins = PeW = 48.53%, while the probability that Paul wins = PaW= 1-PeW = 51.47% (Peter si favoured)

2) The bet will be pretty fair at n=16 or 17

Step-by-step explanation:

Since each car number plate is independent of the others, then the random variable X=number of cars that have the same last two digits follows a binomial distribution. Thus the probability distribution is

P(X) = n!/((n-x)!*x!)*p^n*(1-p)^(n-x)

where

p= probability that a car has the same last 2 digits = {00, 11, ...,99}/{00, 01, 02, ........ 98, 99} = 10/100 = 1/10

n= number of cars = 16

Then the probability that Peter wins PeW is:

PeW=P(X≥2) = 1- P(X<2) = 1- F(X=2) = 1 - 0.5147 = 0.4853 = 48.53%

therefore

Probability that Peter wins = PeW = 48.53%

Probability that Paul wins = PaW= 1-PeW = 51.47% (Peter si favoured)

for n=17 , PeW = 0.518 , PaW= 0.482

for n=15 , PeW = 0.450 , PaW= 0.548

then the bet will be pretty fair at n=16 or 17
