Complete question :
The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29.Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
Answer:
0.10868
Step-by-step explanation:
Given that :
Mean (m) = 3.02
Standard deviation (s) = 0.29
Sample size (n) = 20
Probability of 3.10 GPA or higher
P(x ≥ 3.10)
Applying the relation to obtain the standardized score (Z) :
Z = (x - m) / s /√n
Z = (3.10 - 3.02) / 0.29 / √20
Z = 0.08 / 0.0648459
Z = 1.2336940
p(Z ≥ 1.2336) = 0.10868 ( Z probability calculator)

[tex]\Large\boxed{\tt Answer: Angle ~CDE}[/tex]
[tex]\tt Step-by-step~explanation:[/tex]
Since the sum of the interior angles of a triangle is always 180º, we know that ∠CED and ∠ECD are less than 87º altogether. This is because 93º + 87º = 180º. 87º is already less than 90º, so we know that ∠CDE is the largest angle of this triangle.

Consider two lines having the following equation:
12y-6x=12 line 1
8y+4x=16 line 2
Answer:
x = 1 and y = 1.5
Step-by-step explanation:
Given that,
12y-6x=12 ..... 1
8y+4x=16 ...... 2
Equation (1) can be written as :
2y-x = 2 ... (3)
Equation (2) can be written as :
2y + x = 4 .... (4)
Adding equation (3) and (4)
2y-x + 2y + x = 2 + 4
4y = 6
y = 1.5
Put y = 1.5 in equation (3).
2(1.5)-x = 2
3-x=2
x =1
Hence, the solution of the above equations are (1,1.5).

B. An angle that through 1/12 of a circle has a measure of 1°.
C. An Angle that turns through 10/360 Of a circle has a measure 10°
D. An angle that turns through 1/12 Of a circle has a measure of 12°
Pls help I have to stay up all night answering 200 Questions
The statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
Angle
When two straight lines or rays intersect at a shared terminal, an angle is generated. The angle can be measured in degrees or radians.
How to find a true statement about measuring the angle from the given statements?Let us discuss all four options.
The measure of a whole circle is [tex]360^{o}[/tex]
(A) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]36^{o}[/tex]" is false.
(B) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]1^{o}[/tex]" is false.
(C) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
(D) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]12^{o}[/tex]" is false.
Therefore, option (C) is correct.
Hence, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.

The probability that a women likes the color blue is 10%. The probability of being a women is 40%.What is the probability that a person likes the color blue given that they are a woman?
Answer:
The probability that a person likes the color blue given that they are a woman=0.25%
Step-by-step explanation:
We are given that
The probability that a women likes the color blue=10%=[tex]\frac{10}{100}=0.1[/tex]
The probability of being a women=40%=[tex]\frac{40}{100}=0.4[/tex]
We have to find the probability that a person likes the color blue given that they are a woman.
We know that
Conditional probability formula
[tex]P(A/B)=\frac{P(A\cap B)}{P(B)}[/tex]
The probability that a person likes the color blue given that they are a woman
=[tex]\frac{0.1}{0.4}[/tex]
[tex]=\frac{1}{4}=0.25[/tex]
Hence, the probability that a person likes the color blue given that they are a woman=0.25%
Is -8 - 2(3 + 2x) + 7x equivalent to -30 -13x?
Answer:
They are NOT equivalent.
Step-by-step explanation:
To find if the expressions are equivalent, we have to simplify the first expression.
Solve:
-8 - 2(3 + 2x) + 7x
Use the distributive property.
-8 - 6 - 4x + 7x
Combine like terms.
-14 - 4x + 7x
-14 + 3x
Since they're not the same, this means that the expressions are NOT equivalent to each other.
What is the angle made by two parallel lines
Answer:
180°
Step-by-step explanation:
When any 2 lines make an angle of 180° , they are called as parallel lines . In this case both the lines never intersect each other.
When any 2 lines make an angle of 90° , they are called as perpendicular lines . Both the lines intersect each other.
( Usually most get confused in this question and do write 90° or 0° but 180° is the correct answer)

in triangle DEF, DE=EF and G is the midpoint of EF. if the measure of GDE=10 what is the measure of E?
Note: It seems you may have forgotten to attach the diagram. Hence, I am attaching the potential diagram of your question.
Answer:
The measure of angle E is:
m∠E = 80°
Step-by-step explanation:
Given
The triangle ΔDEF
m∠GDE = 10°
DE = EF
G = midpoint of EF
To Determine
m∠E =?
Solving
As DE=EF and G is the midpoint of EF.
It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.So, the right angle G is m∠DGE = 90°
as
m∠GDE = 10° m∠DGE = 90° m∠E = ?We know that the sum of angles of a triangle is 180°.
m∠GDE + m∠DGE + m∠E = 180°
10° + 90° + m∠E = 180°
m∠E = 180° - 10 - 90
m∠E = 80°
Therefore, we conclude that the measure of angle E is:
m∠E = 80°Cell phone Plan A costs $80 per month and does not come with a free phone. Cell phone Plan B costs $120 per month and comes with a free $840 free phone. If you buy the $840 phone and choose Plan A, how many months is it until your cost is the same as Plan B's?
