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

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)
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].

How many millimeters are equal to one kilometer. Show your work
Answer:
1,000,000
Step-by-step explanation:
1mm=1e-6km
10mm=1e-5km
100mm=1e-4km
1000mm=000.1km
10000mm=0.01km
100000mm=0.1km
500000mm=0.5km
1000000mm=1km
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
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

square centimeters
Answer:
360 cm
Step-by-step explanation:
first you find the triangles which is 1/2 (8×3)=12
then multiply by 2=24
I'm not too sure what your long rectangle measurements are but
I think your long measurement is 28, so then multiply 28 by 12 which is 336. then you add that to 24 which is 360

Step-by-step explanation:
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)
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)

Find the 10th term of the geometric sequence show below
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 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
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.
Find YZ.
Geometry, circles.
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
