As part of a demographic study, a college administrator needed to survey a sample of students from the college. From each major offered at the college, the administrator randomly selected 5 percent of the students with that major to participate in the survey. Which of the following is the best description of the type of sample selected by the administrator?
a)cluster sample
b)convenience sample
c)simple random sample
d)stratified random sample
e)systematic random sample
Answer:convenient I think
Step-by-step explanation:
Saw the first 5 people with the major at the time
The best description of the type of sample selected in the question is;
Option D; Stratified Random Sample
We are told that for the demographic study, the college administrator randomly selected 5% of the students with the particular major randomly.
Since they were chosen randomly, it is clear that this is a type of random sampling that was not done with a convenient sample. Thus, Options A and B are already out of it leaving us with C, D or E
Let us look at the options;
Option C; This sample cannot be a simple random sample because since only 5% are selected from each major, all the students don't have equal chance of being chosen.Option D; This sample is a stratified random sample because the population has been divided into smaller groups by their majors.Option E; This cannot be a systematic random sample because there is no fixed period or interval of selection done.Read more at;https://brainly.com/question/1954758

6 Which equation has a solution of s = 9.5 ? F -5s = -47.5 G -3 + s = 12.5 H --2s 19 J –1 + s = 10.5
Answer:
F. -5s = -47.5
Step-by-step explanation:
F. -5s = -47.5
s = -47.5 / -5
s = 9.5
This is the correct option
G. -3 + s = 12.5
s = 12.5 + 3
s = 15.5 (Incorrect option)
J. –1 + s = 10.5
s = 10.5 + 1
s = 11.5 (Incorrect option)

x = 13
Step-by-step explanation:

an oil company bores a hole 80m deep estimate the cost of boring if the cost is £30 for drilling the first meter with an increase in cost of £2 per meter for each succeeding meter
Answer: £188
Step-by-step explanation:
Given
The depth of the hole is 80 m
For the first meter, it is £30
After that, it is £2 per meter
after a meter, it is 79 m more
The total cost is C
[tex]\Rightarrow C=30+2\times 79\\\Rightarrow C=30+158=188[/tex]

Answer:
15.66 cm
Step-by-step explanation:
180-66.4=113.6°
113.6÷360=0.315555555, which equals 31.55555% of the circumference
2x3.14x7.9=49.612 would be the entire circumference.
So...
31.5555555% of 49.612=15.6554 cm

Answer:
A. 40° and 40°
Step-by-step explanation:
The triangle cannot have two angles measuring 100°, so the remaining two angles must be equal to each other. This eliminates choices B and D.
The sum of angles in the triangle must be 180°. This eliminates choice C.
The two other angles must both be (180° -100°)/2 = 40°.

Answer:
The area is 28 square inches.
Step-by-step explanation:
You need to use the Pyhtagorean Theorem for this one, to find the height.
3^2 + h^2 = 5^2
9 + h^2 = 25
h^2 = 25 - 9
h^2 = 16
h = 4
The Pythagorean Theorem is basically A squared + B squared is C squared, With C always being the hypotenuse, or longest side. A and B are the base and height. You can use either A or B for either base or height, but you must use C for the hypotenuse.

Answer:
a F
Step-by-step explanation:
Normally when converting to scientific notation, I would count how many digits I have to move the decimal dot to get it in between the number, in this case, 36.
If you start shifting the decimal dot to the right and count one every time you shift one digit and go all the way to between 3 and 6, you would count to 5. Since you are shifting to the right, the power of the 10 should be negative. Thus, the answer should be 3.6 × 10[tex]^{-5}[/tex] which is F.

option A F is the answer

A. x= 6, y = 12.12
B. X = 9, y = 12
CX-63, y - 12
D. x=62, y = 24
Answer:
Step-by-step explanation:
Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
The side opposite the 30° angle is 6, so the side opposite the 60° angle is 6√3 and the side opposite the 90° angle is 12.
x = 6√3
y = 12

Answer:
2x + x + 63 = 180 to find x.
m<1 = 78 degrees
m<2 = 102 degrees
Step-by-step explanation:
Combine like terms: 3x + 63 = 180
Subtraction: 3x = 117
Division: 3x/3 = 117/3
Final Answer: x = 39
m<1 = 2(39) = 78 degrees
m<2 = (39 + 63) = 102 degrees
Check work: 102 + 78 = 180
(180 is the measure of a straight line such as the one represented here)

Hello, can someone plz make sure I’m correct. The photo is above !
it looks correct to me
ps. i hate savvas realize
X/2-4=x/3
A 2
B 3
C 12
D6
Need it ASP
Multiply both sides of the equation by 6
x/2*6-4*6=x/3*6
3x-24=2x
This effectively got rid of all the fractions.
Now combine liked terms.
3x-2x-24+24=2x-2x+24 I subtracted 2x from both sides and added 24 on both sides.
x=24
We can check our answers
24/2-4=8
and 24/3=8 so my answer is correct
x=24
