mˆDG=151∘∘
An arc’s length means the same commonsense thing length always means — you know, like the length of a piece of string
The measure of angle ∠DHG of the circle is = 151°
What is Central Angle?The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
r is the radius of the circle
Central Angle = 2 x Angle in other segment
Given data ,
Let the measure of angle ∠DG of the circle be A
Now , the value of A is
Let the measure of m∠DHG = ( 11x - 36 )°
The measure of m∠GHF = ( x + 12 )°
And , the angles m∠DHG = m∠EHF ( vertically opposite angles )
And , the angles m∠GHF = ∠DHE ( vertically opposite angles )
So , 2 ( ( 11x - 36 )° + ( x + 12 )° ) = 360° ( total angle of a circle = 360° )
On simplifying , we get
2 ( 12x - 24 ) = 360
Divide by 2 on both sides , we get
12x - 24 = 180
Adding 24 on both sides , we get
12x = 204
Divide by 12 on both sides , we get
x = 17
Now , the measure of m∠DHG = ( 11x - 36 ) = 151°
Hence , the measure of m∠DHG of circle is 151°

When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h.

a. Paired
b. Not Paired
Answers
Answer:
1. Can be Paired or Not Paired
2. Paired
3. Not Paired
Step-by-step explanation:
Two sets of observations are paired if each observation in one set has a special correspondence or connection with exactly one observation in the other data set.
1. Can be Paired or Not paired
Reason -
We might look at testing the difference of means using a two sample t-test. However, we may also try running a paired t-test.
But its used in cases where the observations are usually from the same populations at different times or through different sources etc.
Hence can't conclude that it is paired or not paired.
2. Paired
Reason -
Each record is a price of the same item from different stores.
3. Not paired
Reason -
This is again a case of testing the difference of means of two-samples (2 independent samples precisely) that are not paired.
1. Can't conclude paired or not paired
2. Paired
3. Not Paired
What do you mean by paired or unpaired?Two sets of observations are said to be paired if each observation in one data set has a specific connection with exactly one observation in the other data set otherwise it is unpaired.
1. Can't conclude paired or not paired because It may look at testing the difference of means using a two-sample test, But it's used in cases where the observations are from the same populations at different times or through various sources, etc.
2. Paired because each item is the price of the same item from different stores.
3. Not paired because in this case of testing the difference of means of two independent samples that are not paired.

if dy/dx = 2 - y, and if y = 1 when x = 1, then y = ??? PHOTO ATTACHED
Answers
Answer:
y=2-e^(1-x)
Step-by-step explanation:
This can be solved by separating the variables.
dy/dx=2-y
Multiply both sides by dx
Divide 2-y on both sides
dy/(2-y)=dx
Integrate both sides
-ln|2-y|=x+c
Multiply both sides by -1
ln|2-y|=-x-c
Equivalent logarithm form
2-y=e^(-x-c)
Minus 2 on both sides
-y=e^(-x-c)-2
Multiply both sides by -1
y=-e^(-x-c)+2
The ordered pair (1,1) belongs to the curve so we have
(I'm going to use this earlier form -ln|2-y|=x+c)
-ln|2-1|=1+c
-ln|1|=1+c
-0=1+c
0=1+c
Minus 1 on both sides
-1=c
Answer:
y=-e^(-x-(-1))+2
Or
y=-e^(-x+1)+2
Or
y=2-e^(1-x)

Answer:
x = 28.5
Step-by-step explanation:
1. Write the equation
4(x+9) = 3(2x - 7)
2. Distribute
4x + 36 = 6x - 21
3. -4x from both sides
36 = 2x - 21
4. +21 on both sides
57 = 2x
5. Divide 2 on both sides
x = 28.5

As part of a study of corporate employees, the director of human resources for PNC, Inc. wants to compare the distance traveled to work by employees at its office in downtown Cincinnati with the distance for those in downtown Pittsburgh. A sample of 40 Pittsburgh employees showed they travel a mean of 370 miles per month. A sample of 35 Cincinnati employees showed they travel a mean of 380 miles per month. Do the Cincinnati employees travel the same distance to work, on average, as the Pittsburgh employees
Answers
Answer:
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
Step-by-step explanation:
40 Pittsburgh employees mean travel time = 370 miles
35 Cincinnati employees mean travel time = 380 miles
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
mean = total distance / Number of employees
For Pittsburgh
370 = x / 40
x = 370 * 40 = 14,800 miles
For Cincinnati
380 = y / 35
y = 380 * 35 = 13,300 miles
