Select the correct answer. Which of these is a key feature of an experimental study? A. The treatment in the experiment should be simple enough for each individual in the experimental group to understand. B. The treatment in the experiment must vary for each individual in the experimental group. C. The treatment in the experiment must be applied to each of the individuals in the experimental group. D. The treatment in the experiment should be short so that each individual is tested quickly.

Answers

Answer 1

Answer:

C. The treatment in the experiment must be applied to each of the individuals in the experimental group.

Step-by-step explanation:

Experimental studies are the studies in which the researcher introduced the intervention and the impact of the study. It usually randomized.

Moreover, it must be applied for each and every individual in the experimental group as the variables & conditions would be vary and the same would be applied so that the actual results may be concluded

Hence, the option c is correct

Step-by-step explanation:

Vertical angles are formed when two lines intersect.  It's a terrible name for them, because the name has nothing to do with the common word "vertica" (up-and-down).

The attached image shows an example of a pair of vertical angles.  Another pair is angles AED and CEB.

What is the approximate circumference of a circle that has a center at (6,2) and passes through the point (20,2)? (Use 3.14 as an approximation for pi)

answers : 126,88,63,44

Answers

Answer:

C = 88

Step-by-step explanation:

So, we know that the circle passes thru the point (20,2), and it's center is (6,2).

The general definition of a circle's radius is the distance from the center to any point on the circle!

Vertically, these points are the same - so if we just subtract 20 from 6 we know the distance between the center and this point on the circle!

[tex]20 - 6 = 14\\r=14[/tex]

Anyhow, we now know that the radius is 14. and the equation for a circle's circumference is as follows:

[tex]r2\pi \\or\\d\pi[/tex]

Insert the values into the equation....

[tex]C = 3.14(14)(2)\\C=87.92[/tex]

87.92 ≈ 88.00

Answers

Answer:

YZ = 44

Step-by-step explanation:

(2x - 6) × 21 = (x + 1) × 30 => intersecting chords theorem

42x - 126 = 30x + 30

Collect like terms

42x - 30x = 126 + 30

12x = 156

12x/12 = 156/12

x = 13

✔️Find YZ:

YZ = 30 + x + 1

Plug in the value of x

YZ = 30 + 13 + 1

YZ = 44

Find the 10th term of the geometric sequence show below

Answers

Answer:

-19,6830x^26

Step-by-step explanation:

The nth term of a geometric sequence is expressed as;

Tn -= ar^n-1

a is the first term

is the number of terms

r is the common ratio

Given

a = -10x^8

r = 30x^10/-10x^8 = -3x^2

n = 10

Substitute

a10 =  (-10x^8)(-3x^2)^10-1

a10 =  (-10x^8)(-3x^2)^9

a10 =  -10x^8)(19,683)x^18

a10 = -19,6830x^26

Hence the tenth term is -19,6830x^26

The ability to find a job after graduation is very important to GSU students as it is to the students at most colleges and universities. Suppose we take a poll (random sample) of 3653 students classified as Juniors and find that 3005 of them believe that they will find a job immediately after graduation. What is the 99 % confidence interval for the proportion of GSU Juniors who believe that they will, immediately, be employed after graduation. (0.812, 0.833) (0.806, 0.839) (0.81, 0.835) (0.816, 0.829)

Answers

Answer:

(0.806, 0.839)

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Suppose we take a poll (random sample) of 3653 students classified as Juniors and find that 3005 of them believe that they will find a job immediately after graduation.

This means that [tex]n = 3653, \pi = \frac{3005}{3653} = 0.823[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.823 - 2.575\sqrt{\frac{0.823*0.177}{3653}} = 0.806[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.823 + 2.575\sqrt{\frac{0.823*0.177}{3653}} = 0.839[/tex]

The answer is (0.806, 0.839)

The dimensions of an iPhone are x – 2 and x + 3. If the area of an iPhone is 14 square inches, find the dimensions of the iPhone

Answers

Answer:

The dimensions of the iphone are 2 inches by 7 inches.

Step-by-step explanation:

Given that,

The dimensions of an iPhone are x – 2 and x + 3.

The area of an iphone is 14 sq inches

We need to find the dimensions of the iPhone. It is in the shape of a rectangle. Its area is given by :

[tex]A=l\times b\\\\(x-2)(x+3)=14\\\\x^2-2x+3x-6=14\\\\x^2+x-6-14=0\\\\x^2+x-20=0\\\\x^2+5x-4x-20=0\\\\x(x+5)-4(x+5)=0\\\\(x-4)(x+5)=0\\\\x=4\ and\ x=-5[/tex]

Neglecting negative value

First dimension = (x-2) = (4-2) = 2 inches

Other dimension = (x+3) = (4+3) = 7 inches

Hence, the dimensions of the iphone are 2 inches by 7 inches.

How many miles will light travel in one day if the speed of light is 300,000,000 meters per second.
(1.62 km = 1 mi)

Answers

Answer:

[tex]d=1.61\times 10^{10}\ miles[/tex]

Step-by-step explanation:

Given that,

The speed of light, v = 300,000,000

eWe need to find the distance light travel in 1 day. We know that,

1 day = 86400 seconds

Distance = speed × time

So,

[tex]d=3\times 10^8\times 86400[/tex]

[tex]d=2.592\times 10^{13}\ m[/tex]

or

[tex]d=0.001610\times 10^{13}\\\\d=1.61\times 10^{-3}\times 10^{13}\\\\d=1.61\times 10^{10}\ miles[/tex]

So, the required distance is equal to [tex]1.61\times 10^{10}\ miles[/tex].
