So, on solving the question we can say all sum of angles of a pentagon are 540 ; x = 340
what is a pentagon?A pentagon is a polygon with five sides that is used in geometry. The inner angles of a straightforward pentagon add up to 540°. Simple or self-intersecting pentagons are both possible. A pentagram is a self-intersecting regular pentagon. Five angles and all sides of a regular pentagon are equal. It is referred to as an irregular pentagon if the side lengths and angle measurements do not match. All outside angles, as far as we are aware, balance out inside angles. The polygon's exterior angle total is therefore equal to n(360°/n). There are five sides to a pentagon, therefore n must equal five. Consequently, 5(360°/5) = 360° is the sum of the pentagon's outer angles.

m is inversely proportional to the square of (p-1).
When p = 4, m = 5.
Find m when p = 6.
Answer:
9/5
Step-by-step explanation:
First we have to find the constant k
m = k/(p-1)^2 (p-1)^ goes on the bottom of the fraction because of the inverse.
5 = k/(4-1)^2
5 = k/3^2
5 = k/9 Multiply both side by 9
45 = k We know can use this constant to solve our problem
m = 45/(6-1)^2
m = 45/5^
m = 45/24
m = 9/5

System of Linear Programming:
z=-3x + 5y
x+y> -22
x-y-4
x - y ≤ 2
Minimum value of z:
The minimum value of z is -12.
Given that the system of linear programming
z=-3x+5y
x+y≥-22
x-y≥-4
x-y≤2
Firstly, we will convert the given constraints into equality as
x+y=-22
x-y=-4
x-y=2
Now, we will take the equation x+y=-22 and taking x as 0 as find y and taking y as 0 to find x, we get
If x=0 then y is
0+y=-22
y=-22
If y=0 then x=-22
So, the points lie on the line x+y=-22 is (0,-22) and (-22,0).
Further, we will take the equation x-y=-4 and taking x as 0 as find y and taking y as 0 to find x, we get
If x=0 then y=4
If y=0 then x=-4
So, the points lie on the line x-y=-4 is (0,4) and (-4,0).
Furthermore, we will take the equation x-y=2 and taking x as 0 as find y and taking y as 0 to find x, we get
If x=0 then y=-2
If y=0 then x=2
So, the points lie on the line x-y=2 is (0,-2) and (2,0).
now, we will find the feasible region of the given constraints as shown in figure.
We will find that each constraint will contain origin or not by substituting (0,0), we get
0+0≥-22 containing origin
0-0≥-4 containing origin
0-0≤2 containing origin
From the graph we can see that the minimum value of x is -13 and minimum value of y is -12.
z=-3x+5y
z=-3x+3y+2y
z=-3(x-y)+2y
minmum value of x-y from the given constraints is
-4≤x-y≤2
From here minimum value of x-y is -4
So, z=-3(-4)+2y
z=12+2y
For the minimum value of z the value of y should be minimum.
From the graph we can see the minimum value of y=-12
So, z=12+2(-12)
z=12-24
z=-12
Hence, the minimum value of z for the system of Linear Programming:
z=-3x + 5y, x+y≥-22, x-y≥-4, x - y ≤ 2 is -12.

On a normal distribution of iq test scores, the average score would be:
The average IQ test score would be 100.
What is a normal distribution?
A probability distribution that is symmetric about the mean or average is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the average value occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.
Average IQ Score
A score of 100 is regarded as the average IQ on various tests. The majority of results (68%) are within one standard deviation of the mean (that is, between 85 and 115). This indicates that the average result is within plus or minus 15 points for almost 70% of test takers.

An angle measures 8.8° more than the measure of its complementary angle. What is the measure of each angle?
Based on the definition of complementary angles, the two angles are: 49.4° and 40.6°.
What are Complementary Angles?Angles that are complementary angles have a sum of 90 degrees.
Let the angle be represented as x
Complement of the angle = (90 - x)
Therefore, we would have:
x = (90 - x) + 8.8
x = 90 - x + 8.8
x = 98.8 - x
x + x = 98.8
2x = 98.8
x = 98.8/2
x = 49.4°
The second angle would be: 90 - 49.4 = 40.6°
The angles are 49.4° and 40.6°.

Matt's family traveled 3/8 of the distance to his grandmother’s house on Saturday. They traveled 3/5 of the remaining distance on Sunday. What fraction of the total distance to his grandmother’s house was traveled on Sunday?
Answer:
3/8
Step-by-step explanation:
Let's use a sample number of 100 miles
If 3/8 was traveled the first day, then 37.5m were traveled on the first day.
Now on Sunday, there are 62.5m remaining in the trip. They travel 3/5 of that, meaning they went 62.5 * 3/5m. This turns out to be 37.5 miles that were traveled on Sunday.
37.5/100 = 3.8

Step-by-step explanation:
Because when you look at the graph, the y value is 5 when the x value is 2.
Answer:
w(2) = 5
Step-by-step explanation:
by using rise over run to find the slope easily, you get a slope of 4 and an equation of w(x) = 4x - 3, -3 being the y-intercept
to calculate w(2):
w(2) = 4(2) - 3

The number of chickens she had was 352
Applications of equationsFrom the question, we are to determine the number of chicken she has
Let c represent chicken
and d represent ducks
From the given information,
Mrs. Anderson had twice as many chickens as ducks
c = 2d ---------- (1)
She sold 272 chickens and 16 ducks and then had half as many chickens as ducks
(c-272) = 1/2(d -16) ---------- (2)
Put equation (1) into (2)
2d - 272 = 1/2(d - 16)
2(2d - 272) = d- 16
4d - 544 = d - 16
4d - d = 544 - 16
3d = 528
d = 528/3
d = 176

What is the result of taking the difference between sample means, minus the null hypothesized difference, divided by the standard error of the difference between means?
The result of taking the difference between sample means, minus the null hypothesized difference, divided by the standard error of the difference between means is the t-statistic.
What is a t-statistic?When deciding whether to accept or reject the null hypothesis in a T test, the t-statistic is used. It functions similarly to a Z-score in that you choose a cutoff point, calculate your t score, and then compare the two. When you have a limited sample size or don't know the population standard deviation, you utilize the t-statistic.
On its own, the t-statistic doesn't actually reveal much. Similar to how the word "average" is meaningless on its own without any context.

Use a triple integral to find the volume of the wedge bounded by the parabolic cylinder yx and the planes zy and z0.
The volume of wedge is 4/15 by use of Triple integral.
According to the statement
we have to find the volume of wedge which is bounded by the parabolic cylinder.
So, because of the given shape of z=√y
the plane y=0 is a boundary, in addition to the given x = 0, z = 0.
so we are in the first octant for all of this. and the further constraint is the plane x + y = 1
Triple integrals are 3 successive integrations, used to calculate a volume, or to integrate in a 4th dimension, over 3 other independent dimensions.
but as a triple integral you would write:
∫x=0 ∫y=0∫z=0 dz dy dx
And after put the values in it and solving it we get the
