Answer:

  • The first factor is itself the sum of two terms
  • The solution is the product of two factors

Step-by-step explanation:

The math symbols of the expression include parentheses, a plus sign, and a multiplication symbol. The order of operations tells you to do the "plus" operation inside parentheses first. The numbers involved in a "plus" operation, or sum, are called "terms." The result is their sum.

Then the second operation in the order of operations is to do the multiplication of the sum on the left of the multiplication symbol by the number to the right of the multiplication symbol. The numbers involved in multiplication are called "factors". The result of multiplication is called a "product."

Matching up this vocabulary with what you see, you realize ...

  • the first factor is the sum of two terms
  • the end result of evaluating the expression is the product of two factors

Consider the null hypothesis, H0: µ = 4,000, at the 1% level of significance. If the z-test statistic is calculated to be 6.00,
kow [346]

Answer:

Option B) Reject null hypothesis      

Step-by-step explanation:

We are given the following in the question:

We are given the null hypothesis:

H_0 = 4,000

\alpha = 0.01

z_{stat} = 6.00

Two tailed z-test

Now, z_{critical} \text{ at 0.01 level of significance } = \pm 2.58

Since,  

The calculated z-statistic does not lie in the acceptance region, we fail to accept and reject the null hypothesis.

Left-tailed z-test

Now, z_{critical} \text{ at 0.01 level of significance } = -2.58

Since,  

z_{stat} > z_{critical}

We fail to accept and reject the null hypothesis.

Right-tailed z-test

Now, z_{critical} \text{ at 0.01 level of significance } = 2.58

Since,  

z_{stat} > z_{critical}

We fail to accept and reject the null hypothesis.

Axel follows these steps to divide 40 by 9: Start with 40. 1. Divide by 9 and write down the remainder. 2. Write a zero after th

“Divide 40 by 9” means 40÷9
Axel did 9÷40


9 goes outside the dog house (⬜️)
9 can’t go into 4 so move to the next number
9 goes into 40 4 times.
9 times 4 equals 36
40 minus 36 equals 4
There are no other numbers under the house can’t go into four and 9 can’t go into 4. That means there is a remained of four.

Sam baby-sat for x hours and earned $75. If he baby-sits for y more hours at the same rate, his total earnings will be $100. Whi
77julia77 [94]

The situation can be modeled with the linear equation:

$75 + y*($75/x) = $100

<h3>Which of the following equations represents this situation? </h3>

We know that if she wors for x hours, she earns $75.

This means that the amount that she gets per hour is:

R = $75/x.

Now, if she works y more hours, then she gets another $25 (for a total of $100).

We can write this as a linear equation:

y*($75/x) = $25

We can rewrite this as:

$75 + y*($75/x) = $100

So the correct option is B.
