Answer: p = 9h

Step-by-step explanation:

     If she makes 9 dollars of every hour of work, this will be a linear equation. We will write it as the following:

      p = 9h

Answer:

9h/p

Step-by-step explanation:

9 x # of hours = total pay

$9 is the dollars for each hour, so you multiply that by how many hours Maria works. You will get the total pay.

The two-way table is an illustration of probability, and the value of P(Adult|Second run) is 0.600

The probability to calculate is given as: P(Adult|Second run)

This means:

The probability that an Adult is selected given that the adult runs the second run

The formula to solve this is:

P(Adult|Second run) = n(Adult and Second run)/n(Second run)

From the table, we have:

n(Adult and Second run) = 219

n(Second run) = 365

So, we have:

P(Adult|Second run) = 219/365

Evaluate

P(Adult|Second run) = 0.600

Hence, the value of P(Adult|Second run) is 0.600

Answer:

k=-2

Step-by-step explanation:

Using substitution to find what you're missing, (in this case k) is when you plug each letter into the other equation:

-4k+3=3k+17

So now solve for k:

subtract 3 from both sides...

-4k=3k+14

subtract 3k from both sides to combine with -4k...

-7k=14

divide -7 from both sides...

k=-2

Answer: y-2 > 1/4(x-4)

Step-by-step explanation:

use slope formula y2-y1/x2-x1 so 2-0/4-(-4) = 1/4

slope int form is y-y1 = m(x-x1)

plug in one point

y-2 = 1/4(x-4)

insert (0,0)

you find y-2 > 1/4(x-4)

The solving of the fractions simply shows that the value of 1 2/3 + 3 1/2 is 5 1/6.

The first fraction give is:

= 1 2/3 + 3 1/2

= 1 4/6 + 3 3/6

= 4 7/6

= 4 + 1 1/6

= 5 1/6

Also 3/4 - 5/7 will be:

= 3/4 - 5/7

= 21/28 - 20/28

= 1/8

It should be noted that when solving fractions, it's important to have a common denominator.

The equation first, third, fifth and seventh are equivalent to the fifth, second, fourth and eighth equation.

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

Equivalent expression can be found out by simplifying the given equation.

First equation given as,

[tex]\left(-14+\dfrac{3}{2}b\right)-\left(1+\dfrac{8}{2}b\right)[/tex]

Simplify it further,

[tex]\left(-14+\dfrac{3}{2}b\right)-\left(1+\dfrac{8}{2}b\right)\\-14+\dfrac{3}{2}b-(1+4b)\\-14+\dfrac{3}{2}b-1-4b\\-15-\dfrac{5}{2}b[/tex]

Third equation in the problem given as,

[tex]\left(5+2b\right)+\left(2b+\dfrac{3}{2}\right)\\5+2b+2b+\dfrac{3}{2}\\4b+\dfrac{13}{2}[/tex]

Simplify it further,

[tex]\left(-14+\dfrac{3}{2}b\right)-\left(1+\dfrac{8}{2}b\right)\\-14+\dfrac{3}{2}b-(1+4b)\\-14+\dfrac{3}{2}b-1-4b\\-15-\dfrac{5}{2}b[/tex]

Similarly, the fifth and seventh equation are simplified and equivalent to the fourth and eight respectively.

Thus, the equation first, third, fifth and seventh are equivalent to the fifth, second, fourth and eighth equation.

Using the Central Limit Theorem, it is found that none of the samples satisfy the normal condition.

It states that the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], as long as at least one of these following conditions is respected.

In this problem, the underlying distributions are skewed, and both sample sizes are less than 30, hence none of the samples satisfy the normal condition.

Answer:

[tex]\boxed{40j + 400}[/tex]

Step-by-step explanation:

Given expression:

[tex]10(0j + 4j + 40)[/tex]

Since the expression inside the parentheses can be simplified, it is suggested to simplify the expression, inside the parentheses, first.

[tex]\implies10[j(0 + 4) + 40][/tex]

[tex]\implies 10[4j + 40][/tex]

Now, simplify the distributive property.

The distributive property can be simplified by multiplying the term outside the parentheses with all the terms inside the parentheses.

[tex]\implies 10[4j + 40][/tex]

[tex]\implies [4j \times 10] + [40 \times 10][/tex]
