a trader bought some eggs at 64 per dozen and sold 2/3 of them at 240/= per tray and the other 1/3 at 225/= per tray.In so doing she made a profit of 450/=.given 1 tray holds 30 eggs and 1 dozen 12 eggs determine the number of eggs she bought.

Note that the number of eggs the above-described **trader **bought is** 180 eggs.** This is solved using simple **arithmetic**.

Let no. of the eggs be x, then

Money the trader paid for eggs = 64/12x = 16/3x

The money the **trader **got from

Seling two third eggs =2/3x*240/30

=16/3x

Money get from one third= x/3*225/30

=5/2

Profit= [16/3x+5/2x] - 16/3x

5/2x = 450

x =450*2/5

=180

Therefore, the **number of eggs** that the trader bought is **180.**

41. How would the graph of the function

y=x2- 3 be affected if the function were

changed to y=x2 + 2?

A. The graph would shift 2 units up.

B. The graph would shift 5 units up.

C. The graph would shift 5 units down.

D. The graph would shift 1 unit up,

**Answer:**

B. The graph would shift 5 units up.

**Step-by-step explanation:**

**Before the change:**

Before the change, the function was given by:

[tex]y = x^2 - 3[/tex]

**After the change:**

After the change, the function was given by:

[tex]y = x^2 + 2[/tex]

Considering the function as it was before the change, it can also be written as:

[tex]y = x^2 - 3 + 5[/tex]

**Which means that 5 was added to the function**, and when a number n is added to a function, there function is shifted n units up. So the correct answer to this problem is given by **option B.**

A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities.

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

Assume that the population variances of both groups are different. Test if there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different. Conduct the hypothesis testing (optional) in paper.

Answer:

We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Step-by-step explanation:

Given :

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

H0 : μ1 - μ2 = 0

H0 : μ1 - μ2 ≠ 0

n1 = 26 ; x1 = 4.05 ; s1 = 0.55

n2 = 32 ; x2 = 5.15 ; s2 = 0.85

Tstatistic :

(x1 - x2) / √(s1²/n1 + s2²/n2)

(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)

-1.1 / 0.1849668

= - 5.947

Using the smaller n;

df = n - 1 ; 26 - 1 = 25

Pvalue = (-5.947, 24)

Pvalue = 0.000001

Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

For each of the following, indicate whether or not a paired analysis would be appropriate.

a. A school cafeteria offers a vegetarian and a nonvegetarian option for lunch every day. For a period of two weeks, you record how many calories are in the vegetarian option and how many calories are in the nonvegetarian option. Your goal is to see if vegetarian options tend to differ with regard to average number calories from nonvegetarian options.

b. A farmer investigates whether talking to cows by name leads to producing more milk. He randomly selects 30 of his cows and randomly assigns 15 to talk to by name and the other 15 not to.

Answer: a. a paired analysis is appropriate

b. a paired analysis is not appropriate

Step-by-step explanation:

The paired analysis sometimes is refered to as a statistical procedure which is used to know if the mean difference that exist between two observations is zero or not. It should be noted that in a paired analysis, each subject is measured twice, and this beings about the pairs of observations.

a. Here, the paired analysis is appropriate due to the fact that similar measurement which are the calories are taken for several days for both the vegetarian and the non vegetarian such are two pairs of sample.

b) In this case, the paired analysis is not appropriate. Here, the pairs of samples don't undergo identical treatment.

In the figure shown above, all the corners form right angles. What is the area of the figure in square units?

9514 1404 393

**Answer:**

70 square units

**Step-by-step explanation:**

The overall outline is 15 units wide and 8 units high, for an area of ...

A = WH

A = (15 units)(8 units) = 120 units²

__

The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...

A = (5 units)(10 units) = 50 units²

__

The shaded area is the difference between the overall area and the white space taken out:

** shaded =** 120 units² -50 units² = **70 units²**

the area of a sector is a secotor = n/360 degrees pie r 2^ what does the term n/360 degrees

**Answer:**

4th option

**Step-by-step explanation:**

[tex]\frac{n}{360}[/tex] represents the fraction of the circle occupied by the sector , that is

The ratio of degrees in the sector's central angle to the total number of degrees in the circle

**Option 4** is correct. **The ratio of degrees in the sector's central angle to the total number of degrees in the circle.**

Fraction is defined as the number of composition constitute the Whole.

**area **of a **sector **is a **secotor **= **n/360 degrees pie r^2**

n =number of fraction at which the circle is divided

mean n = in degrees x number of angles.

and the ratio n/360 degrees

describes the number of partition to the circle.

Thus, the ratio n/360 degrees defines **The ratio of degrees in the sector's central angle to the total number of degrees in the circle.**

The theater sells two types of tickets: adult tickets for $11 and child tickets for $9.

Last night the theater sold 262 tickets for a total of $2482. How many adult tickets did the theater sell last night?

**Answer:**

a=62

**Step-by-step explanation:**

11a + 9c=2482 equation 1

a + c = 262 equation 2

a=262-c isolate value of a in equation

11(262-c) + 9c = 2482 substitute value of a (262-c) into equation 2

2882-11c + 9c= 2482 solve

-2c=-400

c=200

a+c=262

a+200=262

a=62

Check answer:

11a + 9c=2482

11(62)+9(200)=2482

682+1800=2482

2482=2482
