Answer:

The distance is 8 between (7,9) and (-1,9)

Step-by-step explanation:

For:

(X1, Y1) = (7, 9)

(X2, Y2) = (-1, 9)

d=(−1−7)2+(9−9)2√

d=(−8)2+(0)2√

d=64+0√

d=6–√4

d=8

While the response variable or the independent variable that comes under the interval scale in the study is the Warfarin resistance.

c). The group of the individuals in this study is called as  population. The target population in the study is the house mouse which is required as the mutation in Vkorc 1 gene from the hybridizing with Algerian mouse.

d). The study is a manipulative experiment as the changes that have already introduced in house mice and the treatments are under control.

e). No in this study the researcher did not use any random sample.

Answer:

58.23

Step-by-step explanation:

The amount of tip wages will the waiter receive will be $9.77. Then the total meal cost will be $58.63.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

After the Sutton family finished their meal at a local restaurant, the waiter brought them a check for $48.86. If Mrs. Sutton leaves a 20% tip. Then the amount of the tip will be

Tip = 20% of $48.86

Tip = 0.20 x $48.86

Tip = $9.772

Then the total meal cost will be

Total cost = $48.86 + $9.772

Total cost = $58.63

The amount of tip wages will the waiter receive will be $9.77. Then the total meal cost will be $58.63.

Answer:

Step-by-step explanation

S.P of a t.v = rs 7200

Loss % = 25%

Therefore, C.P = S.P (100/100-loss)

=7200(100/100-25)

=7200 x 100/75

=9600

So,now C.P = 9600

Profit% = 25%

Therefore, S.P = C.P (100+profit/100)

=9600(100+25/100)

=9600 x 125/100

=12000

So,the price he should sell to gain 25%

=12000

Answer:

a two sample t test

Step-by-step explanation:

The inferential statistical test that would be most appropriate for this scenario is a two-sample t-test option fifth is correct.

A t-test is a hypothesis-testing technique for analyzing the means of one or two populations. A t-test can be used to see if a single group differs from a known value, if two groups differ from each other (an independent two-sample t-test), or if paired measurements show a significant difference.

Based on the information provided, there are two techniques, each with nine technicians. The sample sizes are tiny, in other words. Furthermore, the two samples are unrelated to one another. As a result, a two-sample t-test is appropriate.

Thus, the inferential statistical test that would be most appropriate for this scenario is a two-sample t-test option fifth is correct.

Answer:

The measure of angle wxz is 130°?

Answer: 20/10

Step-by-step explanation:

Take (calculate) 4/5 of 2/5 mile:

4x5= 20

---- * ---- = 20/10

2x5= 10

The section that needs to be repaved is 1/2 of a mile.

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now it is given that,

Length of road = 4/5 of a mile

Road needs to repave = 2/5 of the road

Thus, road needs to repave = 2/5 of 4/5

⇒ road needs to repave = (2*4)/(5*5)

⇒ road needs to repave = 10/20

or, road needs to repave = 1/2

Thus, the section that needs to be repaved is 1/2 of a mile.

Answer: B and D

Step-by-step explanation:

I see you picked the first one which is close but not right. This isn't right because you are adding the area of both rectangles together and in the first choice the + 7 should be 7y because y is the height which is why the 4th choice is correct and the second choice if you distribute you get 5y + 7y which is the same so that would be right as well.

Answer:

LCM is the least common factor the number common in both and left numbers, Therefore, HCF and LCM of numbers 24 and 36 are 12 and 72 respectively.

Step-by-Step Explanation:

Find the prime factorization of 24

24 = 2 × 2 × 2 × 3

Find the prime factorization of 36

36 = 2 × 2 × 3 × 3

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 3 × 3

LCM = 72

The value of the account to reach $13,140 will take 14 years assuming no deposits or withdrawals are made .

Compound interest is an interest accumulated on the principal and interest together over a given time period. The interest accumulated on a principal over a period of time is also accounted under the principal.

[tex]A = P (1+ \frac{r}{100} )^{n}[/tex]

Where,

A = final Amount

P = initial principal

r = rate per annum

n = time in years

According to the question

Camden invested (P) = $7,200

Interest rate per month (r) = 4.4%

Amount  to reach =  $13,140

now , using Formula of compound interest

[tex]A = P (1+ \frac{r}{100} )^{n}[/tex] ere , n = n/12 (as concluding monthly wise )

Substituting the values

[tex]13140 = 7200 (1+ \frac{4.4}{100} )^{\frac{n}{12} }[/tex]

1.825  = [tex](1+ \frac{4.4}{100} )^{\frac{n}{12} }[/tex]

1.825  = [tex](1..044 )^{\frac{n}{12} }[/tex]

n ≈ 168 months (approx.)

n = 14 years (nearest year)

Hence, the value of the account to reach $13,140 will take 14 years assuming no deposits or withdrawals are made .
