PLEASE HELP!!!

igomit [66]

Answer:

Step-by-step explanation:

-2(p + 4) = 3 - 3p + 1p.....combine like terms

-2(p + 4) = 3 - 2p...distribute the -2 through the parenthesis

-2p - 8 = 3 - 2p

-2p + 2p = 3 + 8

0 = 11 <==== no solution

if it is a false statement, it has no solutions

if it ends like : 6 = 6 or -2 = -2, then there is infinite solutions

if it ends like : x = 8 or x = -5, then there is 1 solution

A stand was selling 8 mangos for 10 dollars at a farmer's market.

MaRussiya [10]

(Ms)Kisha is correct.

How?

Well, I figured this out by using common sense. 8 mangoes are 10 dollars. Since the price is higher than the amount, so it has to be at least more than one.

We could write more ratios. You can always write more ratios. You just multiply/divide both sides. Examples below:
2:5
16:20

Answer:

Probability that their hair was done by Amy is 0.475.

Step-by-step explanation:

We are given that Sally's Hair Salon there are three hair stylists. 36% of the hair cuts are done by Chris, 26% are done by Karine, and the rest are done by Amy.

Let the Probability of hair cutting done by Chris = P(C) = 0.36

Probability of hair cutting done by Karine = P(K) = 0.26

Probability of hair cutting done by Amy = P(A) = 0.368

Also, let NS = event that customer is not satisfied with his cutting

So, Probability that customers are not satisfied given that their hair cutting is done by Chris = P(NS/C) = 0.05

Probability that customers are not satisfied given that their hair cutting is done by Karine = P(NS/K) = 0.06

Probability that customers are not satisfied given that their hair cutting is done by Amy = P(NS/A) = 0.08

Now, a customer leaving the salon is selected at random. If the customer is not satisfied, the probability that their hair was done by Amy is given by = P(A/NS)

For finding the above probability we will use the concept of Bayes' Theorem;

SO, P(A/NS) = $\frac{\text{P(A) \times P(NS/A)}}{\text{P(C) \times P(NS/C) + P(K) \times P(NS/K) +P(A) \times P(NS/A) }}$ $\frac{P(A) \times P(NS/A) }{P(C) \times P(NS/C) +P(K) \times P(NS/K) +P(A) \times P(NS/A) }$

= $\frac{0.38 \times 0.08}{0.36 \times 0.05+0.26 \times 0.06+0.38 \times 0.08}$

= $\frac{0.0304}{0.064}$

= <u>0.475</u>

<em>Hence, the probability that their hair was done by Amy is 0.475.</em>

Square of a binomial x^2+2x+1

garik1379 [7]

To put an equation into (x+c)^2, we need to see if the trinomial is a perfect square.
General form of a trinomial: ax^2+bx+c
If c is a perfect square, for example (1)^2=1, 2^2=4, that's a good indicator that it's a perfect square trinomial.
Here, it is, because 1 is a perfect square.
To ensure that it's a perfect square trinomial, let's look at b, which in this case is 2.
It has to be double what c is.
2 is the double of 1, therefore this is a perfect square trinomial.
Knowing this, we can easily put it into the form (x+c)^2.
And the answer is: (x+1)^2.
To do it the long way:
x^2+2x+1
Find 2 numbers that add to 2 and multiply to 1.
They are both 1.
x^2+x+x+1
x(x+1)+1(x+1)
Gather like terms
(x+1)(x+1)
or (x+1)^2.
