It’s none, there is none.

Answer: none

1) combine like terms: 4x + 8 = 4x - 13

2) Add 13 to both sides (addition property of equality)

3) Subtract 4x from both sides (subtraction property of equality)

4) 21 does not equal 0

What's the mean of 0,1,3,2

Artist 52 [7]

Hi Tim! Thanks for asking a question here on Brainly.

<span>☛ To find the mean, we add together all the numbers and then divide it by the amount of numbers there are.
</span>
0 + 1 + 3 + 2
= 6
<span>= </span>6 / 4 = 1.5

Answer: 1.5

Assume that it is true that people can not tell the difference between Coke and Pepsi. If a sample of 15 people participated in

pantera1 [17]

Answer:

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to the normal distribution if

$np \geq 10$

and

$n(1-p)\geq 10$

In this problem, we have that:

$n = 15$

First condition

$np \geq 10$

$15p \geq 10$

$p \geq \frac{10}{15}$

$p \geq \frac{2}{3}$

Second condition

$n(1-p) \geq 10$

$15(1-p) \geq 10$

$15 - 15p \geq 10$

$-15p \geq -5$

Multiplying by -1

$15p \leq 5$

$p \leq \frac{1}{3}$

p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.

The answers to the questions are:

1. x = 4

2. x = 1.5

3. x = 1.875

4. x = 1

<h3>2 step equation:</h3>

1. 4x + 3 = 19

4x = 19 - 3

4x = 16

divide by 4

x = 4

<h3>2 step equation w/ fractions:</h3>

(4/3)x + 5 = 17

= 1.33x + 5 = 7

Take like terms

1.33x = 7-5

1.33x = 2

divide through by 1.33x to get 2

x = 2/1.33

x = 1.5

<h3>3. Distributive Property:</h3>

4x(6 - 2) - 10 = 20

Multiply and open the bracket

24x - 8x - 10 = 20

Take like terms

16x = 20+10

16x = 30

x = 30/16

= 1.875

<h3>4. Decimals:</h3>

4.3x + 0.7 = 5

4.3x = 5 - 0.7

4.3x = 4.3

x = 1

Answer:

We have to multiply P(A) and P(B) which is 0.0045 * 0.01 * 100 (to make it a percentage) = 0.0045%.
