area of triangle: ((1st leg)x(2nd leg))/2=(4x3)/2=6

1st leg=4

2nd leg=6-3=3

Answer:

The answer is D

Step-by-step explanation:

y=kx

9=k

Plug it in they are all true.

The table represents a direct proportion between the number of tickets sold and the total cost will be D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

For the linear relationship, the slope will remain constant.

Let's check all the options, then we have

A. The slope is given as,

m = (2 - 0) / (1 - 0) = (4 - 2) / (3 - 1)

m = 2 ≠ 1

B. The slope is given as,

m = (4 - 0) / (2 - 0) = (6 - 4) / (4 - 2)

m = 2 ≠ 1

C. The slope is given as,

m = (7 - 5) / (2 - 1) = (9 - 7) / (3 - 2) = (11 - 9) / (4 - 3)

m = 2 = 2 = 2

The y-intercept is 3.

D. The slope is given as,

m = (18 - 9) / (2 - 1) = (27 - 18) / (3 - 2) = (36 - 27) / (4 - 3)

m = 9 = 9 = 9

The y-intercept is zero.

The table addresses an immediate extent between the number of tickets sold and the all-out cost will be D.

#SPJ2

Answer:

m<N = 130°

m<K = 50°

x = 28

Step-by-step explanation:

angle N and angle K are supplementary so the sum of their measures is 180°

4x + 18 + 2x - 6 = 180 add like terms

6x + 12 = 180 subtract 12 from both sides

6x = 168 divide both sides by 6

x = 28 to calculate the measurements of angle N and K replace x with 28

N = 4x + 28 so 4 × 28 + 18 = 130°

N = 2x - 6 and 2×28 - 6 = 50°

Answer:

No

Step-by-step explanation:

because the sum 12+15= 27

and 27 not come between 12 & 1

Answer:

12 and 78

Step-by-step explanation:

The sum of complementary angles is 90 degrees

X+(x-66) = 90

2x = 156    x =  78

78-66 = 12

Answer:

A. 2

Step-by-step explanation:

From the diagram, it is indicated;

AD = DB = 3t,

AC = 7t + 6

CE = EB = 4t

Perimeter = 48 units

Perimeter = AD + DB + AC + CE + EB

Plug in the values

48 = 3t + 3t + 7t + 6 + 4t + 4t

Add like terms

48 = 21x + 6

48 - 6 = 21x + 6 - 6

42 = 21x

42/21 = 21x/21

2 = x

x = 2

Answer:

Step-by-step explanation:

Let's say we had a sample of 100 people. We'll split them into two equal groups of 50 each. The two groups will be the treatment and control groups. The treatment group, aka experimental group, is where the actual drug is given. The control group is where the fake drug is given. People in the control group must not know the pill is fake. For more info, check out the placebo effect. In short, this is when a person takes a fake pill and thinks they get better, and that positive mentality helps them actually get better.  

If both the treatment and control groups improve (on average) together, then that means the fake pill is just as good as the real thing. Consequently, it means the real pill isn't effective at all. If on the other hand the experimental group does better overall compared to the control group, then we can see that the real pill is doing what it's intended to do. Of course, there are a lot of complicated factors involved, as there is with anything dealing with medicine. I haven't mentioned anything about side effects or things of that nature. In this simplified viewpoint of the world, we're only considering the one factor of whether or not the drug clears up the psoriasis on the skin.

To make things fair, it's best to randomly generate numbers so that you randomly assign people into each group. That way you have representative samples. Also, when drawing the sample of 100 people, make sure that's as random as possible to help represent the population as best as possible. The fact that the people in the control group not knowing that they are taking the fake pill means we have a single blind experiment. A double blind experiment is when even the researchers are not sure who is taking the real pill vs the fake pill. Double blind experiments are encouraged to prevent the researcher's bias from affecting the results.

To keep participants from knowing whether or not they are in the control group, the common solution is to provide a sugar pill. The pill will not cause any side effects and will not cause any improvements to health. It's simply sugar. To the participant, it seems like the real thing since they can't taste the difference or detect anything seems different.

Answer:

Randomly select a sample of people with psoriasis. Randomly assign them to one of two groups. Give one group the​ treatment, and withhold it from the other group. Give both groups similar looking​ pills, so neither knows which group they are in.

Answer:

A. 390

Step-by-step explanation:

An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].

Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.
