The answer is A. above the fraction bar. The denominator lives below the fraction bar.

Question

What is the excluded value of -2x/17
a. x=0
b. x=2
c. x=17
d. no excluded values

Solution 1

Answer is d: no excluded values.

There is only excluded values if the variable x is in the denominator.

There is only excluded values if the variable x is in the denominator.

Question

A circle has a circumference of 10. It has an arc of length 9/2

Solution 1

Given that aÂ Â circle has a circumference of 10 and an arc of length 9/2, thus the fraction of the arc length will be:

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45Ã—360Â°

=162Â°

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45Ã—360Â°

=162Â°

Question

Anja collected data about the number of dogs 9th-grade students own. She created this histogram to represent the data and determined that it is skewed right. Which statement is true about Anjaâ€™s claim?

Solution 1

D)Â She is correct; the histogram is skewed to the right because there is less data on the right side.

Solution 2

Question

Mary has 7 1/4 yard of fabric. she cuts off 3/4 foot fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. how long will each piece be?

Solution 1

7 1/4 - 3/4 = 6 5/4 - 3/4 = 6 2/4Â

6 2/4 Ã· 3 = 26/4 Ã· 3 = 26/4 x 1/3 = 2 1/6

**Answer: 2 1/6 yd**

6 2/4 Ã· 3 = 26/4 Ã· 3 = 26/4 x 1/3 = 2 1/6

Question

Yun is making some investments in the stock market. Stock for Company A has a 30% chance of losing $12,000, a 45% chance of breaking even, and a 25% chance of earning Yun $11,000. Assuming Yun would like the odds to be in favor of her gaining money, should she invest in Company A? Explain. a. no, 7,700 > 3,600
b. yes, 7,700 > 3,600
c. yes, 3,600 > 2,750
d. no, 3,600 > 2,750

Solution 1

We have been given that company A has a 30% chance of losing $12,000.

Let us calculate the amount that Yun can loose.

Now, 45% chance of breaking even. It means neither loss nor profit.

Then, 25% chance of earning Yun $11,000.

Let us calculate the amount of profit

Since, 3,600 > 2,750. It means that Yun will be in loss on investing in the company.

**Hence, she will not invest in the company A.**

d is the correct option.

d. no, 3,600 > 2,750

Solution 2

D.Â no, 3,600 > 2,750.

Question

A lawn roller is 1 m wide and 80 cm high. What area is covered in each revolution

Solution 1

The area for each revolution is given by:

Â A = 2 * pi * r * l

Â Where,

Â r: roller radius

Â l: roller width

Â We have then:

Â A = 2 * 3.14 * (0.80 / 2) * 1

Â A = 2.512 m ^ 2

Â**Answer:**

Â**The area that is covered in each revolution is:**

Â**A = 2.512 m ^ 2**

Â A = 2 * pi * r * l

Â Where,

Â r: roller radius

Â l: roller width

Â We have then:

Â A = 2 * 3.14 * (0.80 / 2) * 1

Â A = 2.512 m ^ 2

Question

The graph of y = f(x âˆ’ 3) is a _____ of the graph of y = f(x).

Solution 1

shift

These are common types of transformations of functions. Many functions have graphs that are simple transformations of the parent graphs, that are the most basic functions. In this way, we can use **vertical and horizontal shifts **to sketch graphs of functions. These are** rigid transformations** because the basic shape of the graph is unchanged. Therefore is a **Horizontal Shift, **so the graph of the function **has been shifted 3 units to the right.**

Solution 2

**Answer: shifted 3 units to the right.**

**Step-by-step explanation:**

Question

Divide 969 by 26.
A. 32 r 6
b. 29 r 17
C. 37 r 7
D. 28 r 5

Solution 1

On **dividing **969 by 26 will get **quotient **= 37 and **remainder **= 7

**Division **is the process of **splitting **a number or an amount into equal parts, **division **is one of the four basic operations of arithmetic, the ways that numbers are **combined **to make new numbers, it is used for **splitting **into equal parts or groups, It is **breaking **a number up into an equal number of parts.

Given that, we are asked to **divide** 969 by 26.

969 / 26

Since, 26 is a two** digits number**, we will first take the first **two digits** of the number given,

The number which we can **multiply **with 26 to get the **closest** number from 96 is 3, 26 Ã— 3 = 78

96-78 = 18

Now,

18 + the **remaining **number 9, will make a number = 189

189 / 26

Since, 18 is less than 26, and 189 is less than 260 (10 times 26) that means a number which is closest to 189 in the table of 26 is between 1 times 26 to 10 times 26, therefore, we will consider the whole number 189,

7 times 26 = 182, which is closest to 189,

189-182 = 7

Since, first we get 3 and now 7

Therefore, the **quotient **will be 37 and the **remainder **is 7

Hence, on **dividing **969 by 26 will get **quotient **= 37 and **remainder **= 7

Solution 2

**Answer:**

**The Answer is =37 r 7**

**Step-by-step explanation:**

969 / 26

26 * 37 = 962

969 - 962 = 7

969 / 26 = **37 R 7.**

Question

A flower vase has 5 white lilies, 4 pink roses, and 6 yellow carnations. One flower is chosen at random and given to a woman. Another flower is then chosen at random and given to a different woman. What is the probability that both flowers are pink roses?

Solution 1

Total flowers = 5 + 4 + 6 = 15

Pink roses = 4

P(two pink roses) = (4/15)(3/14) = 2/35

**Answer: 2/35**

Pink roses = 4

P(two pink roses) = (4/15)(3/14) = 2/35

Solution 2

Question

A flower vase has 5 white lilies, 4 pink roses, and 6 yellow carnations. One flower is chosen at random and given to a woman. Another flower is then chosen at random and given to a different woman. What is the probability that both flowers are pink roses?

Solution 1

Â 4/15Â·3/14Â =Â 0.057 so it's b.) 0.057

Solution 2

5+4+6=15 2/15=.133333 or 13% or 2/15
