An experiment was conducted to study the use of 95% ethanol versus 20% bleach as a disinfectant in removing contamination when culturing plant tissues. The experiment was repeated 15 times with each disinfectant, using cuttings of eggplant tissue. The observation reported was the number of uncontaminated eggplant cuttings after a 4-week storage.

Disinfectant 95% Ethanol 20% Bleach
Mean 3.74 4.86
Variance 2.78097 0.17142
n 15 15
Pooled variance 1.47620

1. Are you willing to assume that the underlying variances are equal?

a. Yes
b. No

2. Using the information from part (A), are you willing to conclude that there is a significant difference in the mean numbers of uncontaminated eggplants for the two disinfectants tested?

Answers

Answer:

a. Yes

Step-by-step explanation:

The term common variance means that each population has the same variance.

If σ²=σ₁²=σ₂² but unknown then the unbiased pooled or combined estimate of the common variance σ² is calculated.

In the given problem the pooled variance is calculated .

Therefore we assume that that the underlying variances are equal.

Using Student's t distribution

The given data is

Mean               3.74             4.86

Variance     2.78097       0.17142

n                       15                     15

Pooled variance 1.47620

t= x`1- x`2/ Sp √1/n1+ 1/n2

t = 3.74-4.86/ 1.47620 √1/15+ 1/15

t= -1.12/ 0.539

t= -2.0779

Taking the significance level ∝= 0.05 the

Value of the critical region is  t≤ - t∝/2  and  t≥  t∝/2 = ±2.048 for

Degrees of freedom = n1+n2- 2= 28

Hence the calculated value of t -2.0779 falls in the critical region therefore null hypothesis is rejected and  and it is concluded that the means are not equal.

The PRIDE club is selling school t-shirts and hoodies during football games. Two t-shirts and 2
hoodies will sell for $76.50. Five t-shirts and 3 hoodies will sell for $140.25. How much does
each shirt sell for?

Answers

Answer:

Cost of each hoodies = $25.5

Cost of each t-shirt = $12.75

Step-by-step explanation:

Given:

Cost of 2 t-shirt and 2 hoodies = $76.50

Cost of 5 t-shirt and 3 hoodies = $140.25

Find:

Cost of each t-shirt

Computation:

Assume;

Cost of each t-shirt = t

Cost of each hoodies = h

So,

2t + 2h = 76.50..........eq1

5t + 3h = 140.25..........eq2

Eq 1 x 2.5

5t + 5h = 191.25.............eq3

Eq3 - Eq2

2h = 51

h = 25.5

Cost of each hoodies = $25.5

2t + 2h = 76.50

2t + 2(25.5) = 76.50

t = 12.75

Cost of each t-shirt = $12.75

what is Volume?

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Volume is the three- dimensional property, its basic units is always in cube.

Volume generally told us how much capacity can handle which we express it with the help of cubic units.

Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.

Answers

Answer:

Triangle = 34

A = ½ (b × h)

Parallelogram = 63

A = b × h

Trapezoid = 24

A= (a+b)/2 x h

The one with the greatest area is Parallelogram (63)

State whether f^-1 (x) is a function given the equation

Answers

Answer:

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Step-by-step explanation:

Existence of an inverse function:

An inverse function will exist if: f(a) = f(b) only if a = b.

In this question:

[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]

[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]

[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]

[tex]16 - a^2 = 16 - b^2[/tex]

[tex]a^2 = b^2[/tex]

[tex]a = \pm b[/tex]

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Rhombus CDEF is shown below. If the slope

Answers

Answer:

Step-by-step explanation:

trust

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.

What is a rhombus?

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.

Given that, the rhombus is CDEF and the slope of FC is 5/2.

Here, sides FC and CD are perpendicular.

The slope of a line perpendicular to given line is m₁=-1/m₂

Slope of CD is -2/5.

Therefore, option B is the correct answer.

Marilyn County operates on a calendar year basis. It uses a Capital Projects Fund to account for major capital projects and a Debt Service Fund to accumulate resources to pay principal and interest on general obligation debt. It does not use encumbrance accounting in the Capital Projects Fund. The following transactions occur: 1. On January 1, 2013, Marilyn County issues general obligation bonds in the amount of $1,000,000 to build a community center. The debt will be paid off in 20 equal semiannual installments of $50,000 over a 10-year period commencing October 1, 2013, with interest of 4 percent per annum paid on the outstanding debt. 2. The county realizes that the community center will cost more than it originally anticipated. On May 1, the county transfers $20,000 from its General Fund to its Capital Projects Fund to help meet project costs. 3. Construction is completed on July 1, 2013, and the community center is ready for occupancy. The county pays the contractor a total of $1,020,000 on July 1. The county anticipates that the community center will have a useful life of 20 years. 4. On September 30, 2013, the General Fund transfers an amount to the Debt Service Fund that is sufficient to pay the first debt service installment, which is due October 1. 5. The county pays the debt service due on October 1. Use the preceding information to do the following: Required: a. Prepare journal entries to record these transactions in the Capital Projects Fund, the General Fund, and the Debt Service Fund. b.
