what is the length of the arc with a measure of 200 degrees in a circle with a radius of 31 inches?
Answer:
403π/9 or 140.67
Step-by-step explanation:
First, you have to find the circumference of the circle
Circle circumference equation:
Circumference = dπ (Circumference = diameter x pi)
You have a radius of 31 which is equal to 62 diameter (diameter is double the radius)
So:
C = 62π
Now, you need to know that a full circle is 360 degrees and we want only 200 degrees of that,
So in other words, you want 200/360 of the circle's circumference.
You can find the measure of the 200 degree arc by doing
62π x [tex]\frac{200}{360}[/tex] = [tex]\frac{403pi}{9}[/tex] or 140.67
what scale factor is used to draw the longer trapezoid?
Measurements of angles
Answer:
x = 60
Step-by-step explanation:
Since this triangle is an isosceles triangle, the angle next to the 60 degrees is 60 as well. The interior angles of a triangle adds up to 180 degrees, so:
60 + 60 + x = 180
120 + x = 180
x = 60

For a sample of n = 16 scores, what is the value of the population standard deviation (o) necessary to produce each of the following standard error values?
a. Ом = 8 points
b. Ом =4 points
с. Ом = 1 point
Using the Central Limit Theorem, it is found that the values of the population standard deviation [tex]\sigma[/tex] needed are given by:
a) [tex]\sigma = 32[/tex]
b) [tex]\sigma = 16[/tex]
c) [tex]\sigma = 4[/tex]
What does the Central Limit Theorem state?By the Central Limit Theorem, the sampling distribution of sample means of size n has standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this problem, we have that n = 16.
Item a:
s = 8, hence:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]8 = \frac{\sigma}{\sqrt{16}}[/tex]
[tex]\sigma = 32[/tex]
Item b:
s = 4, hence:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]4 = \frac{\sigma}{\sqrt{16}}[/tex]
[tex]\sigma = 16[/tex]
Item c:
s = 1, hence:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = \frac{\sigma}{\sqrt{16}}[/tex]
[tex]\sigma = 4[/tex]

Mrs. Woods wants to give each of her 25 students a pencil on the first day
of school. The pencils come in boxes of 12. How many boxes will she need
to purchase?
Answer
3 boxesStep-by-step explanation:
So she needs to give 25 pencils to each student.
1 box = 12
number of boxes = 25/12
=2.08
round it to 3
Therefore she need 3 boxes
Which symbol < > = will make the comparison true 4/6 and 4/8
Answer:
4/6 > 4/8
Step-by-step explanation:
To see if the following is true:
We can cross multiply:
[tex]\frac{4}{6}\neq \frac{4}{8}[/tex] {4* 8 = 32} {4*6=24}
Thus,
[tex]\frac{4}{6}=32[/tex]
[tex]\frac{4}{8}=24[/tex]
Hence, [tex]\frac{4}{6} > \frac{4}{8}[/tex]
We can also turn them into decimal:
[tex]\frac{4}6=0.6667[/tex]
[tex]\frac{4}{8}=0.5[/tex]
0.5 is NOT greater than 0.6667 which also means that 4/8 is NOT greater than 4/6.

What is the mean absolute deviation of the following set
of data?

9

10
Answer:
3
Step-by-step explanation:
You want the mean absolute deviation of the set of numbers ...
{9, 2, 9, 9, 5, 4, 9, 1, 4, 10}
MADThe mean of this 10-number set of data is 6.2. The mean absolute deviation (MAD) is found by subtracting that from the members of the dataset, taking the absolute values of the result, and finding the means of those.
The attachment shows those calculations.
The MAD of this set of data is 3.
__
Additional comment
The period (decimal point) in the column of numbers suggests this is a 6-number dataset, and the last 4 numbers are answer choices. If that is the case, none of those answer choices is correct. That is why we assumed that this problem has a 10-number dataset.
When you're calculating this by hand, you only need to consider the values for which the deviation is negative. The MAD is twice their total absolute value, divided by the number of numbers in the dataset. Here, that is 2(4.2+2.2+5.2+2.2+1.2)/10 = 3. (Numbers 2, 5, 4, 1, 4 are less than the mean of 6.2.)

If the difference of 3 / 4 and 1 / 6 of a number is 7, find the number and also verify your answer.
The computation of the equation illustrates that the number will be 46.4.
How to solve the equation?Let the number be represented as x.
Therefore, the the difference of 3 / 4 and 1 / 6 of a number is 7 will be computed as follows:
(1/6 × x) - 3/4 = 7
0.167x = 7 + 3/4
0.167x = 7.75
x = 7.75/0.167
x = 46.4
Therefore, the number is 46.4.

4sin^2(theta) + 4 = 5
Answer:
Θ = (π/6) + πn
Θ = (5π/6) + πn
Step-by-step explanation:
4sin²Θ + 4 = 5
-4 -4
4sin²Θ = 1
÷4 ÷4
sin²Θ = (1/4)
√sin²Θ = √(1/4)
sinΘ = (1/2), (-1/2)
-------------------------
Θ = arcsin (1/2)
Θ = (π/6)
to find the quadrant subtract π
Θ = π - (π/6)
Θ = (5π/6)
Find the period
2π / |b|
b = 1
2π/1 = 2π
The sin Θ function is 2π, so values will repeat 2π in both directions.
Θ = (π/6) + 2πn (n is the variable)
Θ = (5π/6) + 2πn
-------------------------------------------------------------------------------------------------------
sin Θ = (-1/2)
Θ = arcsin (-1/2)
Θ = (-π/6)
To find the second function add π
Θ = 2π + (π/6) + π
Θ = (7π/6)
Find the period
2π/|b|

Θ = (11π/6) will repeat every 2π in both directions

Θ = (π/6) + 2πn
Θ = (5π/6) + 2πn
Θ = (7π/6) + 2πn
Θ = (11π/6) + 2πn
(π/6) + π = (7π/6)
(5π/6) + π = (11π/6)

the sum of 3x and 1 is greater than-5 and less than or equal to 10
Answer:
x is greater than -2 and less than or equal to 3
Step-by-step explanation:
so the 3x + 1 is greater than -5
so 3x is greater than -6
we divide both sides by 3
then we find out that x is greater than -2
we also know that 3x + 1 is less than or equal to 10
so 3x is less than or equal to 9
we divide both sides by 3
then we find out that x is less or equal to 3
so we can say that x is greater than -2 and less than or equal to 3

Determine the value(s) for which the rational expression 10w−52w2+11w+5 is undefined. If there's more than one value, list them separated by a comma, e.g. w=2,3.
An expression is defined as a set of numbers, variables, and mathematical operations. The value(s) for which the rational expression (10w−5)/(2w²+11w+5) is undefined is -1/2 and -5.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The value for which the function will not be defined is the value of w which will make the denominator of the rational function zero. This values can be found by factorizing the denominator of the function. Therefore,
2w² + 11w + 5 = 0
2w² + 10w + 1w + 5 = 0
2w(w+5) + 1(w+5) = 0
(2w+1)(w+5) = 0
w = -1/2 , -5
Hence, the value(s) for which the rational expression (10w−5)/(2w²+11w+5) is undefined is -1/2 and -5.
