The most appropriate design is an experiment (A), this can be applied by having a control and an experimental group (B), and one benefit is that you can identify the effectiveness (C).

Different from an observational study, a census or a survey that are used to collect information about people's preferences, an experiment allows you to test the effectiveness of a treatment, which is the main purpose in this case.

The bst is to have a control and an experiment group. For example you select 30 dogs and use the repelant in 15 dogs; then all dogs are exposed to ticks. As a result you can evaluate how effective the repelant is by comparing the two groups.

Answer: $1,372

Step-by-step explanation:

If using the Labor Statistics Document

A men’s median weekly earning with Bachelor’s degree only is $1,384 * 4 weeks = $5,536

A women’s medium weekly earning with a Bachelor’s degree only is $1,041 * 4 weeks = $4,164

Subtract $5,536 - $4,164 = $1,372

The full sentences are:

The typical monthly salary for women with bachelor's degrees is $3,020.

The typical annual salary for a guy with an associate's degree is $36,432.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Every month has four weeks.

The median monthly income is thus:

Earnings = 4 * $755

Earnings = $3020

As a result, the typical monthly salary for women with bachelor's degrees is $3,020.

The median annual income:

A man with an associate's degree makes $759 each week.

A month has four weeks, while a year has twelve months.

Hence, the annual median income is:

Earnings = 4 x 12 x $759

Earnings = $36,432

Thus, the typical annual salary for a guy with an associate's degree is $36,432.

The Span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.

Linear Span of vectors can be represented as

let [tex]x_{1} and x_{2}[/tex] be two non collinear vectors its span be written as [tex]x=a_{1} x_{1} +a_{2} x_{2}[/tex]   where [tex]a_{1}, a_{2}[/tex] are arbitrary scalars.

Subspace of vectors : a subset A of a vector space V is called a subspace of V if A is itself a vector space under scalar multiplication and addition defined on V.

The Span of two vectors is a vector space containing two vectors. Hence the span is also a vector space . It is sufficient to notice that any two independent vectors from subspace can be the basis.

Zero vector is the linear combination of these basis vector.

hence it is not possible to have a span of two non collinear vectors that does not contain origin .

Therefore, The span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.

Step-by-step explanation:

The value of P(2 tails) is 37.5%, the correct option is B.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

The sample space=  {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

Now,

The sample space for tossing a coin 3 times is {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}, where H represents heads and T represents tails.

To determine P(2 tails), we need to count the number of outcomes in which there are 2 tails, and divide that by the total number of outcomes:

Number of outcomes with 2 tails: There are three outcomes with 2 tails: TTH, THT, and HTT.

Total number of outcomes: There are eight outcomes in total.

P(2 tails) = number of outcomes with 2 tails / total number of outcomes = 3/8 = 0.375, which is equivalent to 37.5%.

Therefore, the probability the answer will be 37.5%.

The change in distance between you and your friend from the beginning of the race is 8 7/24.

It should be noted that before the race, you start 4 5/8 behind your friend and at the halfway point, you are 3 2/3 ahead your friend.

Therefore, the change in distance will be the addition of the fractions given.

= 4 5/8 + 3 2/3

= 4 15/24 + 3 16/24

= 7 31/24

= 8 7/24

There are 160 possibilities for area codes

We are required to find all the combinations for different area codes

It is given to us that the conditions for the tree digit area code are:

first digit could be any number from 4 through​ 8,

the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7

Using the conditions above, the digits which can be first digit of code = 4 through 8 =4,5,6,7,8

the digits which can be second digit of code= 4,5,6,7

the digits which can be third digit of code = 0,1,3,4,5,6,8,9

number of possibilities for first digit= 5

number of possibilities for second digit=4

number of possibilities for third digit= 8

Therefore, total number of possibilities of code   = number of possibilities of first digit x number of possibilities of second digit x number of possibilities of third digit = 5 x 4 x 8=160

Therefore, there are 160 possibilities for area codes

n²+13n+40,

This is why;

Observe only the right side. The number is (n+8)(n+5).

Let's elaborate on that using FOIL.

F = When we multiply the first two terms, n and n, we obtain n².

O = outer instructs us to multiply n by 5 to get n*5 or 5n from the outer terms.

I = inner instructs us to multiply the inner expressions 8 by 8 and n by n to obtain 8n.

Since 8 and 5 are multiplied by L, we obtain 8*5 = 40.

Add up the outcomes: n²+5n+8n+40 = n²+13n+40

Observe how the phrase is a little bit simplified by the combination of the like terms (5n and 8n).

This demonstrates how (n+8)(n+5) becomes n²+13n+40, becoming the correct response. For all values of n, none of the other options are valid equations;

The value of l is. We use simple substitution of values to find the value of l is 48.

We have been given the equation V=lwh where l is the length, we can say that the given equation is that of volume of a cuboid where l is the length, w is the width and h is the height of the cuboid. We know the values of V,w and h. We have to substitute the values of V,w and h in the equation V=lwh inorder to find the value of l. Substitution method is generally used for solving system of equations where we first solve the value of one variable and then substitute the value in the other equation to find the value of the other variable. Since we only have one equation and we know the value of 3 of the 4 variables we only have to solve for one.

V=lwh

l=V/wh =[tex]\frac{576}{6.12} =\frac{576}{72}[/tex]= 48

The number of uniforms the Spartan Basketball team purchased was 13.

The number of uniforms bought by the Spartan Basketball team can be determined using the mathematical operations of subtraction and division.

In the first place, the cost of equipment is subtracted from the total cost.  The remainder is divided by the unit cost of uniforms.  The quotient is the number of uniforms bought.

Total cost incurred = $1,860

Cost of equipment = $300

Remainder cost = $1,560 ($1,860 - $300)

Unit cost per uniform = $120

The number of uniforms bought = 13 ($1,560/$120)

Thus, the number of uniforms the Spartan basketball team purchased was 13.
