Answers
We know that RS is parallel to PQ by comparing RS and PQ and both vector have the same value and hence prove to be parallel.
We know that R, S, Q and P are midpoints of OC, CB, BA and OA, and we are given that OR = a, CS = b and OP = c
we have to prove that RS is parallel to PQ,
therefore we need to find, PQ = PA + AQ,
= c - c + a + b = a + b,
since we get that PA = OP = c
therefore when we compare RS and PQ ,we get,
RS = PQ = a + b
now that it is clear that both the vectors are same and have the same value we can conclude that they are parallel.

For the given matrix A find a 3x2 matrix B such that AB=I, where I is the 2x2 identity matrix. [Hint: If B1 and B2 are the columns of B, then ABj = Ij.]A =1 2 11 1 1
Answers
AB = [1 0] is the 2x2 identity matrix so, AB=I.
[0 1]
To find a 3x2 matrix B such that AB=I, we need to solve the equation:
A × B = I
where I is the 2x2 identity matrix. We can use the hint given to us to find the columns of B.
Let B1 and B2 be the columns of B. Then we have:
A × B1 = I1
A × B2 = I2
where I1 and I2 are the columns of the 2x2 identity matrix I.
We can solve for B1 and B2 by setting up and solving the following systems of linear equations:
For B1:
1 × B1[1] + 1 × B1[2] = 1
2 × B1[1] + 1 × B1[2] = 0
1 × B1[1] + 1 × B1[2] = 0
For B2:
1 × B2[1] + 1 × B2[2] = 0
2 × B2[1] + 1 × B2[2] = 1
1 × B2[1] + 1 × B2[2] = 0
Solving these systems of equations, we get:
B1 = [-1, 1]
B2 = [1, -1]
Therefore, the 3x2 matrix B that satisfies AB=I is:
B = [-1 1]
[ 1 -1]
[ 0 0]
We can verify that AB is indeed equal to the 2x2 identity matrix I:
A × B = [1 2 1] × [-1 1 0] = [(-1)+2 (1)+(-1) 0+0] = [1 0]
[1 1 1] [ 1 -1 0] [ 1+1 (1)+(-1) 1+0] [0 1]
Therefore, AB = I:
AB = [1 0]

Solve for the y-intercept given a slope of -2 and a point of (3,-2)
Answers
After solving for the line with slope as -2 and point (3,-2) , the y intercept is (0,4) .
We use the Point Slope form of a linear equation to write the equation of a line given its slope and a point on the line.
So , the point slope form is ⇒ y - y₁ = m(x - x₁) ;
Where m = slope , and (x₁, y₁) = point on line .
So , by using the slope (m = -2) and point (x₁, y₁) = (3, -2),
Substituting these values and simplifying further ,
We get ; ⇒ y -(-2) = (-2)×(x - 3) ;
⇒ y + 2 = (-2)×(x) + (-2)×(-3) ;
Subtracting 2 from both sides,
we have ;
⇒ y = -2x + 4
The y intercept of line is value of "y" when x = 0.
So , we substitute x = 0 in the equation of line y = -2x + 4 ;
that means ⇒ y = -2(0) + 4 ;
⇒ y = 4 .
Therefore, the y intercept of the line with slope "-2" and passing through the point (3, -2) is (0, 4).

a coin is flipped and die is rolled once. what is the probability of flipping a heads on the coin and rolling a 5 on the die? give your answer as a reduced fraction.
Answers
The probability of flipping a heads on the coin and rolling a 5 on the die is 1/12 if a coin is flipped and die is rolled once.
The sample space for the coin toss is {H,T}, so there are two possible outcomes. The favorable one is H.
The probability of flipping a heads on the coin is equal to 1/2.
Die has six faces, meaning six possible outcomes, but we’re only interested in one of those outcomes: that roll of a 5. That means that only 1 in 6 outcomes is desirable and we can write it as 1/6
The probability of rolling a 5 on the die is equal to 1/6.
Since a coin is flipped and die is rolled independently, the joint probability is a product of above probabilities.
Therefore, the probability of flipping a heads on the coin and rolling a 5 on the die equals

Remember what we know about vertical angles and solve for x.
Then tell me the measure of Angle R.
Answers
The value of x by using vertical angles is 4, and the measure of angle R is 34°
Vertical Angles.Vertical angles are angles that are formed and are opposite of each other when two lines intersect. Vertical angles are congruent angles, it implies that they exhibit the same angle measure. Vertical here refers to the fact that they have the same Vertex (corner point).
From the information given:
6x + 10 = 8x + 2
6x - 8x = 2 - 10
-2x = -8

a random sample of 75 units is drawn from a production process every half hour. the fraction of nonconforming product manufactured is 0.01. what is the probability that if the fraction nonconforming really is 0.01?
Answers
The probability of obtaining a random sample of 75 units from a production process where the true fraction of nonconforming product is 0.01 is extremely high. This is because 0.01 is an extremely low fraction, meaning that out of the 75 units in the sample, only 0.75 would be expected to be nonconforming.
The probability that the fraction of nonconforming product is exactly 0.01 (with 0.75 nonconforming units out of 75) can be calculated using the binomial distribution. This distribution assumes that each unit has an independent probability of being nonconforming, and that this probability is the same for each unit. The probability that the sample will have exactly 0.75 nonconforming units out of 75 is 0.907.
Thus, the probability that the true fraction of nonconforming product is exactly 0.01 is very high, and it is likely that a random sample of 75 units drawn from the production process will have a fraction nonconforming that is close to 0.01.

a group of roommates equally shared the 6000$ in rent for an apartment. when four of the roomates moved out, those roomates remaining still shared the 6000$ rent equally, but each roomate's share of the rent increased by 250$. how many roomates were there orginally
Answers
The original number of roommates was 6, determined by comparing the original and new shares of rent per roommate and solving for the minimum number of roommates that satisfies the inequality.
Let's assume that there were 'x' original roommates in the apartment.
When the rent was shared equally among 'x' roommates, each roommate's share was:
[tex]6000/x[/tex]
After four roommates moved out, the remaining roommates continued to share the same rent of $6000 but each person's share increased by $250. So the new share per roommate is:
[tex](6000/x) + 250[/tex]
Since the number of roommates decreased by 4, the new number of roommates is:
[tex]x - 4[/tex]
We know that the new share per roommate is greater than the original share per roommate, so we can set up the following inequality:
[tex](6000/x) + 250 > 6000/x[/tex]
Simplifying the inequality, we get:
[tex]250 > 6000/x - 6000/x[/tex]
[tex]250 > 6000/x^2[/tex]
[tex]x^2 > 24[/tex]
[tex]x > 4.9[/tex]
Since the number of roommates must be a whole number, the minimum value for x is 6.
Therefore, there were originally 6 roommates in the apartment.
The solution involves setting up an inequality to compare the original share of the rent per roommate with the new share of the rent per roommate, and then solving for the minimum number of original roommates that satisfies the inequality.

Answers
In a sample of 20 men, the mean height was 178 cm and a sample of 30 women, the mean height was 164 cm, then the mean height for both groups combined is approximately 172.4 cm.
To find the mean height for both groups combined, we need to calculate the weighted average of the means of each group, where the weight of each group is proportional to its sample size.
We can begin by finding the total height of all the individuals in both groups combined. The total height for the men's group would be 20 multiplied by the mean height of 178 cm, which is 3560 cm.
Similarly, the total height for the women's group would be 30 multiplied by the mean height of 164 cm, which is 4920 cm. Adding these two values gives a total height of 8480 cm for both groups combined.
Next, we need to find the total sample size, which is the sum of the sample sizes of the two groups. The total sample size is 20 + 30 = 50.
Finally, we can calculate the weighted average of the means of each group using the formula:
Weighted average = (weight of group 1 * mean of group 1 + weight of group 2 * mean of group 2) / (weight of group 1 + weight of group 2)
In this case, the weights of each group are proportional to their sample sizes. Therefore, the weighted average can be calculated as:
Weighted average = (20/50 * 178 cm) + (30/50 * 164 cm) = 172.4 cm
In summary, to find the mean height for both groups combined, we need to calculate the weighted average of the means of each group, where the weight of each group is proportional to its sample size. This is done by multiplying the sample size of each group by its mean height, adding the values, and then dividing by the total sample size.

Determine the occupant load of a one room daycare that is 20' by 30' !
Answers
The occupant load of a one room daycare that is 20' by 30' is 17 people.
The occupant load of the daycare room can be determined by using the formula:
Occupant load = Area of room / Occupant load factor
From the case, we know that the area of the room is 20' x 30', then:
Room area = 600 square feet.
The occupant load factor for a daycare is typically 35 square feet per person. This means that each person in the daycare should have at least 35 square feet of space.
Using the formula, the occupant load of the one room daycare is:
Occupant load = 600 square feet / 35 square feet per person = 17.14 people
Therefore, the occupant load of the one room daycare is 17 people. This means that the daycare can safely accommodate 17 people at one time.

Answers
The correct option for a parabola with given details is D i.e. A curve declines through (negative 1, 6), (0, 4), (1, 2), (2, 1), (4, 0) and (6, 1) on the x y coordinate plane.
What exactly is a parabola?
A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).
In general, if the directrix is parallel to the y-axis, the typical parabola equation is: y² = 4ax.
If the parabola is sideways, i.e., the directrix is parallel to the x-axis, the conventional parabola equation is x² = 4ay.
Aside from these two, if the parabola is in the negative quadrants, the equation can also be y²= -4ax and x² = -4ay.
Now,
The Graph is drawn for option D in the image and it matches the
