The length of a rectangular lot is 6 feet less than 3 times its
width. Its area is 222 square feet.
Its width is
feet and its length is
feet.

Answers

Answer:

Its width is 9.66 feet and length is 22.98 feet.

Step-by-step explanation:

Let l is length and b is width of a rectangular lot.

Length, l = (3b-6) feet

The area of the lot is 222 sq feet.

The area of a rectangle is given by :

[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]

It is a quadratic equation. The solution of the above equation is given by :

b = 9.66 feet and -7.66 feet

Neglecting negative answer, the width of the lot is 9.66 feet.

Length, l = (3(9.66)-6) = 22.98 feet

Hence, its width is 9.66 feet and length is 22.98 feet.

Answers

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

Answer:

D) y=-5/2x; y=-20

Step-by-step explanation:

If y varies directly with x, then y=kx where k is our proportionality constant

Therefore, since y=-5 when x=2, we have -5=k(2) where k=-5/2

This means that when x=8, y=(-5/2)(8)=-20, making choice D correct

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.

Answers

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.

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,

Answers

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.

Answers

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.

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. ​

Answers

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

What is the justification for the above response?

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.
