Answer:
[tex]Parts = \frac{1}{8}[/tex]
Step-by-step explanation:
Given
[tex]N = \frac{1}{6}[/tex] -- Not good enough
[tex]M = \frac{3}{4}[/tex] --- Minor repairs
Required
The parts that are not good enough but only needs minor repairs
To do this, we simply multiply M by N
[tex]Parts = M * N[/tex]
[tex]Parts = \frac{3}{4} * \frac{1}{6}[/tex]
Divide by 3/3
[tex]Parts = \frac{1}{4} * \frac{1}{2}[/tex]
[tex]Parts = \frac{1}{8}[/tex]
Hence, the part of the donation is 1/8
3. Write an equation for the line that is perpendicular to the given line and that passes through the given point. y = 4x + 1 (12,-6)
a)y = -1/4x + 12
b)y = -1/4x - 3
c)y = -1/4x - 6
d)y= -1/4x + 3
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
If the line is perpendicular, it will have a opposite reciprocal slope.
So, the slope will be -1/4.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
-6 = -1/4(12) + b
-6 = -3 + b
-3 = b
Plug in the slope and y intercept into y = mx + b
y = -1/4x - 3
So, the correct answer is D. y = -1/4x + 3
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
Because it is the "Correct Answer"

In the United States, voters who are neither Democrat nor Republican are called Independent. It is believed that 11% of voters are Independent. A survey asked 33 people to identify themselves as Democrat, Republican, or Independent. A. What is the probability that none of the people are Independent? Probability = B. What is the probability that fewer than 6 are Independent? Probability = C. What is the probability that more than 2 people are Independent? Probability =
Answer:
a) 0.0214 = 2.14% probability that none of the people are Independent.
b) 0.8516 = 85.16% probability that fewer than 6 are Independent.
c) 0.8914 = 89.14% probability that more than 2 people are Independent.
Step-by-step explanation:
For each people, there are only two possible outcomes. Either they are independent, or they are not. For each person asked, the probability of them being Independent voters is the same. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
It is believed that 11% of voters are Independent.
This means that [tex]p = 0.11[/tex]
A survey asked 33 people to identify themselves as Democrat, Republican, or Independent.
This means that [tex]n = 33[/tex]
A. What is the probability that none of the people are Independent?
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
0.0214 = 2.14% probability that none of the people are Independent.
B. What is the probability that fewer than 6 are Independent?
This is
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X = 2) = C_{33,2}.(0.11)^{2}.(0.89)^{31} = 0.1724[/tex]
[tex]P(X = 3) = C_{33,3}.(0.11)^{3}.(0.89)^{30} = 0.2202[/tex]
[tex]P(X = 4) = C_{33,4}.(0.11)^{4}.(0.89)^{29} = 0.2041[/tex]
[tex]P(X = 5) = C_{33,5}.(0.11)^{5}.(0.89)^{28} = 0.1463[/tex]
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0214 + 0.0872 + 0.1724 + 0.2202 + 0.2041 + 0.1463 = 0.8516[/tex]
0.8516 = 85.16% probability that fewer than 6 are Independent.
C. What is the probability that more than 2 people are Independent?
This is:
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X < 2) = 0.0214 + 0.0872 = 0.1086[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.1086 = 0.8914[/tex]
0.8914 = 89.14% probability that more than 2 people are Independent.

1. Refer to the figure at the right. Line a is parallel to line b and m2 is 135 °. Find each given angle measure. Justify your answer
m9+m<10
m1
m6
m4+ m5
this means angle
Answer:
∠9 + ∠10 = 135° combined, they are alternate equal to ∠2
∠1 =45° it is supplementary to ∠2
∠6 = 45° it is corresponding congruent to ∠8 which is alternate
equal to ∠1
∠4 + ∠5 = 135° combined, they are corresponding congruent to ∠2
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
All the angles are mentioned on the diagram.
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.

I need help! ABCD is a rectangle.
m<1 =
m<6 =
m<3 =
Answer:
m∠1 = 24°
m∠3 = 66°
m∠6 = 66°
Step-by-step explanation:
They are all near the corners of the rectangle
The corners always equal 90°
But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°
Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.
m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So
90 - 24 = 66
So both m∠3 and m∠6 = 66°

To find:
The value of [tex]f(x+h)[/tex] in simplified form.
Solution:
We have,
[tex]f(x)=x^2+2x+1[/tex]
Putting [tex]x=x+h[/tex], we get
