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
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

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]

Solve the equation below. Show all work and round four decimal places.
In(x^4)=6
Answer:
The solution is [tex]x = 4.4817[/tex]
Step-by-step explanation:
The inverse of the ln function is the exponential, which means that to solve this question, we apply the exponential to both sides.
We have that:
[tex]\ln{(x^4)} = 6[/tex]
Applying exponential to both sides:
[tex]e^{\ln{(x^4)}} = e^6[/tex]
[tex]x^4 = e^6[/tex]
[tex]x = \sqrt[4]{e^6}[/tex]
[tex]x = (e^6)^{\frac{1}{4}}[/tex]
[tex]x = 4.4817[/tex]
The solution is [tex]x = 4.4817[/tex]

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)

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

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)

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

Answer:
0 = 0
Step-by-step explanation:
Subtract 4 from both sides of the equation
3 + 4 − 4 = 3 + 4 − 4
Simplify
Subtract the numbers
3 = 3 + 4 − 4
3 = 3
Subtract 3x from both sides of the equation
3 − 3 = 3 − 3
Combine like terms
0 = 3 − 3
Result
0 = 0
