The continuous random variable N has a normal distribution with mean 7.5 and standard deviation 2.5. For which of the following is the probability equal to 0 ?
P(N=8)
P(N>8)
P(N<8)
P(7 8)
Using the normal distribution, it is found that P(X = 8) is equals to zero.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.As in any continuous distribution, the probability of an exact value, that is, P(X = x), is of 0.Hence, from the last bullet point, it is found that P(X = 8) is equals to zero.

If the radius of a circle is decreased by 20%, find the percentage decrease in its area.
Answer:
36%
Step-by-step explanation:
Area of circle is
[tex]\pi {r}^{2} [/tex]
If the radius is decreased by 20%. Then the radius will be
80% of the original radius.
So our radius is 0.8.
So our area is
[tex]\pi(0.8r) {}^{2} [/tex]
[tex]\pi(0.64 {r}^{2} )[/tex]
Since pi is constant, the radius only really matters.
We went from
[tex]1 {r}^{2} [/tex]
to
[tex]0.64 {r}^{2} [/tex]
So our area will decrease by 36%
Proof: Let the radius be 10.
So the area of circle will be
[tex]\pi(10) {}^{2} = 100\pi[/tex]
Let our other radius is 8 because 8 is a 20% decrease of the orginal radius
[tex]\pi(8) {}^{2} = 64\pi[/tex]
Next, we subtract the area to find decrease in area
[tex]100\pi - 64\pi = 36\pi[/tex]
Since pi is constant, we can ignore it so our decrease in area is 36%

Problem 3
Answer: Not possible to solveA triangle cannot be constructed with these parameters.
----------------------------
Explanation:
Use the Law of Sines to find angle B
sin(A)/a = sin(B)/b
sin(120)/12 = sin(B)/13
sin(B) = 13*sin(120)/12
sin(B) = 0.93819419
B = arcsin(0.93819419) or B = 180 - arcsin(0.93819419)
B = 69.75047247 or B = 180 - 69.75047247
B = 69.75047247 or B = 110.24952753
These angle values are approximate.
-----------
If B = 69.75047247, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 69.75047247)
C = -9.75047247000001
We get a negative result which isn't valid.
This means B = 69.75047247 isn't valid either.
-----------
If B = 110.24952753, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 110.24952753)
C = -50.24952753
We get a similar conclusion here as well.
-----------
No matter what value of B we go with, we end up with a negative value for angle C.
Negative angles are not allowed.
Therefore, we cannot construct a triangle with sides a = 12, b = 13 and angleA = 120 degrees.
This is one example of an SSA triangle leading to no possible solutions. Refer to the SSA ambiguous case for more info.
-----------
Check out the diagram below. Imagine that point B can be anywhere on the dotted circle. Imagine it can rotate around as in an animation. This circle is centered at point C and has radius a = 12. No matter where point B is placed, we cannot get it to land on the horizontal line to therefore form a triangle. Simply put: side a = 12 is too short.
I used GeoGebra to make the diagram and make sure it's to scale. This is to visually verify that we cannot construct such a triangle with these parameters.

In a class of 25 students, 7 students have 2 brothers or sisters. 4 students have 1 brother or sister. 3 students do not have any brothers or sisters. 6 students have 3 brothers or sisters. The remaining students have 4 brothers or sisters.
Part A
Use the drop-down menus to make the statement true.
The scale of the line plot should have Choose... (0, 1, 7, 8) as its least data value and Choose... (3, 4, 7, 25) as its greatest data value.
Part B
Use the drop-down menus to make each of the statements about the number of dots true.
There will be Choose... (1, 2, 3, 4) dots above 1.
There will be Choose... (4, 5, 6, 7) dots above 4.
There will be three dots above Choose... (0, 1, 2, 3)
Using the basis of how we must represent data on a graph, we can write:
A) The scale is 1, and the maximum value is 7.
B)
Above 1 we already know that there must be 4 dots. Above 4, there must be 6 dots. We only will have 3 dots above the 0 (3 students have 0 brothers or sisters).How to correctly represent the data?
First, we know that the sample has 25 people in it, an we measure the number of brothers, in such a way that the number of brothers/sisters goes from 0 to 5.
Then, the horizontal axis must go from 0 to 4, in such a way that above the 0 we have 3 dots (because 3 students have 0 brothers or sisters), above the 1 we have 4 dots (because 4 students have one brother or sisters), and so on.
7 students have 2 brothers or sisters (that is the largest number) so the vertical axis must go from 0 to 7.
A) The scale of the line plot is 1, each dot represents 1 student. And the greatest value is 7 (for the students with 2 brothers or sisters).
B)
Above 1 we already know that there must be 4 dots. Above 4, there must be 6 dots. We only will have 3 dots above the 0 (3 students have 0 brothers or sisters).If you want to learn more about plotting data, you can read:

Find the value of xx, yy, and zz, in the rhombus below.
Answer:
Step-by-step explanation:
A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
3x - 4 = 3y + 8 = -2x - 9 = 39
The value of x is 43/3
The value of y is 31/3
The value of z is -24
What is a rhombus?A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
We have,
Rhombus:
All four sides are equal.
So,
3x - 4 = 3y + 8 = -2x - 9 = 39
Now,
3x - 4 = 39
3x = 39 + 4 = 43
3x = 43
x = 43/3
3y + 8 = 39
3y = 39 - 8
3y = 31
y = 31/3
-2z - 9 = 39
-2z = 39 + 9
-2z = 48
z = -24
Thus,
The value of x is 43/3
The value of y is 31/3
The value of z is -24

Increase 400 by 10% and then decrease the answer by 10%
Answer:80
Assume the number to be 400 for instance,
10% of 400 increased = 400 + ( 10/100 × 400 )
= 400 + 40 = 440
The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
Answer:
400.
10% of 400 is 40 (Simply reduce the hundreds place to the tens place)
So now we have 440.
Decrease it by 10% again, and that brings you right back to 400.

Help i don’t understand this question
Answer:
828 in²
Step-by-step explanation:
To find the surface area of a triangular prism, you find the area of each side and add them together.
Find the area of each rectangular side:
Side 1 : 9 × 20 = 180 in²
Side 2 : 15 × 20 = 300 in²
Side 3 : 12 × 20 = 240 in²
Find the area of the triangular sides:
Area of a Triangle = [tex]\frac{1}{2}[/tex]bh
As you can see, 9 and 12 both work as the height/base for the triangular sides, so
Δ Side 1 = [tex]\frac{1}{2}[/tex]bh = [tex]\frac{1}{2}[/tex](9)(12) = 54
Δ Side 2 is also 54.
Add the areas of all the sides together:
180 + 300 + 240 + 54 + 54 = 828 in²
