A company performs linear regressions to compare data sets of two similar products. If the residuals for brand A form an increas
Radda [10]
I think the correct answer would be B. If the residuals for brand A form an increasing curve, and the residuals for brand B form a U-shaped pattern, then neither of the data is likely to be linear. In order to be linear, the residuals of both data set should be, more or less, linear or approaching linearity in nature. Therefore, the linear regression that was done would not give good results since it is only applicable to linear data sets. Also, you can say that the relation of the data sets of the products are not linear. It would be best to do a curve fitting for both sets by using different functions like parabolic functions.

Which of the following are remote interior angles of 5? Check all that apply.
soldier1979 [14.2K]
Yes, ∠1 and ∠2 are the remote interior angles of ∠5, but ∠3 is not.
You're looking for the remote interior angles, so while ∠3 has a measure that when added to ∠5 = 180°, it is adjacent to ∠5 so it is not remote from it.

If a perimeter of a room is 78 feet, what is the area of the floor of the room?
Andrei [34K]
The perimeter doesn't tell you the area, and neither of them
can be calculated by knowing the other one.

Check this out:

Dimensions   Perimeter   Area      .

1  by  38              78          38 square feet
2  by  37              78          74 square feet         
3  by  36              78         108 square feet         
5  by  34              78         170 square feet         
10  by  29            78         290 square feet         
15  by  24            78         360 square feet         
17  by  22            78         374 square feet         
19  by  20            78         380 square feet         
19.5 by 19.5        78          380.25 square feet

Nine same perimeters, nine different areas !

Here's one more ... a long skinny one:

1 inch by 38ft 11in     Perimeter = 78 ft.    Area = 3.24 square feet.

Instructions: Find the missing side lengths. Leave your answers as radicals in simplest
anyanavicka [17]

Answer:

A. x = 11√3

B. y = 11

Step-by-step explanation:

A. Determination of the value of x.

Angle θ = 60°

Hypothenus = 22

Opposite = x =?

We can obtain the value of x by using sine ratio as illustrated below:

Sine θ = Opposite / Hypothenus

Sine 60 = x / 22

√3/2 = x / 22

Cross multiply

2 * x = 22√3

Divide both side by 2

x = (22√3) / 2

x = 11√3

B. Determination of the value of y.

Angle θ = 60°

Hypothenus = 22

Adjacent = y =?

We can obtain the value of y by using cosine ratio as illustrated below:

Cos θ = Adjacent / Hypothenus

Cos 60 = y / 22

½ = y / 22

Cross multiply

y = ½ × 22

y = 11

ests for tuberculosis like all other diagnostic tests are not perfect. QFT-G is one of such tests for tuberculosis. Suppose that
Brut [27]

Answer:

P(POSc/Sc)

Step-by-step explanation:

As,

POS= Test has positive results

and

S=Adult has tuberculosis.

The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time.

In the above statement 76.53% describes the probability of adult who don't have tuberculosis gets the negative results as test is correctly identifying.

So, getting negative results means that not positive results and for this event the notation of complement POSc is used. Also, not having tuberculosis can be denoted as Sc. So,

POSc= Test has negative results

Sc=Adult hasn't tuberculosis

Thus, P(POSc/Sc) depicts the probability of adults not having tuberculosis gets correct results.

Hence,  P(POSc/Sc)=76.53%
