Which of the following approaches can be used to construct a parallelogram? Select one: a. Measure equal segments on parallel lines, then join the endpoints of these segments. b. Construct two congruent angles, then bisect them. c. Construct the perpendicular bisector of a segment, then bisect two of the right angles. d. Construct two perpendiculars to a parallel line.
Final answer:
The correct approach to constructing a parallelogram is to measure equal segments on parallel lines and then join the endpoints of these segments, which ensures opposite sides are equal and parallel.
Explanation:
The student has asked which of the following approaches can be used to construct a parallelogram. The correct approach is Measure equal segments on parallel lines, then join the endpoints of these segments, which corresponds to option a. This method utilizes the properties of parallelograms, where opposite sides are equal in length and parallel to each other. The Euclidean Geometry postulates that relate to this method include E1 Two points determine a line, E2 Line segments can be extended, and the Parallel postulate: Given a line and a point not on the line, no more than one line can be drawn through the point and parallel to the given line.
To construct a parallelogram, you can follow these simplified steps:
Select any two parallel lines.
Measure and mark equal length segments on each of the lines.
Join the corresponding endpoints of these segments to form the parallelogram.

A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work
The number of games won is 104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of games = 160
Percentage of games won = 65%
Now,
The number of games won.
= 65% of 160
= 65/100 x 160
= 104
Thus,
The number of games won is 104.

Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.
A=1 ≥ 2x
B=6x ≥ 3 + 8x – 4
and on a graph
.5 shaded to the left
- .5 shaded to the right
.5 shaded to the right
checking all that apply the correct answers would be A B and C
The correct answers are:
A) 1 ≥ 2x ; B) 6x ≥ 3 + 8x – 4 ; and .5 shaded to the left
Explanation:
Our inequality given is 6x ≥ 3 + 4(2x - 1). First we use the distributive property:
6x ≥ 3 + 4(2x) + 4(-1)
6x ≥ 3 + 8x - 4
This means A is correct.
Next we can subtract 8x from each side:
6x-8x ≥ 3+8x-4-8x
-2x ≥ 3-4
-2x ≥ -1
Divide both sides by -1 (remember to flip the inequality symbol):
-2x/-1 ≥ -1/-1
2x ≤ 1
This can also be written as 1 ≥ 2x, so B is correct.
To finish solving this, divide both sides by 2:
2x/2 ≤ 1/2
x ≤ 0.5
To graph this, we circle 0.5 and fill it in (since it is less than or equal to), and shade to the left (since it is less than).

How do you convert from a radical expression to a rational exponent?
Im just a little confused so if someone could explain this to me, thatd be great!
To convert a radical expression to a rational exponent, identify the root index of the radical as this will be the denominator of the rational exponent. The base remains unchanged. The rational exponent is 1 over the root index.
Explanation:To convert a radical expression to a rational exponent, you need to understand the connection between them. In mathematics, the 'nth root of a' can be written as a radical expression or as a to the power of 1/n, which is the rational exponent form.
For example, if we have √a (square root of a), which is a radical expression, it can be written as a^(1/2) in rational exponent form. Similarly, the cube root of a (3√a) translates to a^(1/3).

Every day, the number of network blackouts has a distribution (probability mass function)
x | 0 | 1 | 2
P(x)| 0.7| 0.2| 0.1
A small internet trading company estimates that each network blackout results in a $500
loss. Compute expectation and variance of this company’s daily loss due to blackouts.
I computed this E(x)= .4 , varX= .44, but I don't know how i can find the answer?
The answer is
E(Y ) = 200 dollars,
Var(Y ) = 110, 000 squared dollars.
The expected daily loss of the company due to blackouts, E(Y), can be calculated by multiplying each possible loss (which is the number of blackouts times 500) by the probability of that loss occurring, and summing these products. The variance, Var(Y), is found by first finding the expected value of the square of the loss, E(Y^2), which is done in a similar way to finding E(Y), but by squaring each loss before multiplying by its probability. The variance is then given by E(Y^2) - [E(Y)]^2, resulting in a variance of $110,000.
Explanation:The expectation (or mean) of a random variable Y can be computed by multiplying each outcome by its probability and summing all these products. The random variable Y here is the daily loss corresponding to x blackouts, which is given by 500*x, where x is the number of blackouts. Hence to find the expected daily loss, E(Y), you need to calculate:
E(Y) = 0*0.7 + 1*500*0.2 + 2*500*0.1 = $200
The variance of a random variable is found by taking the expected value of the squared variation of that variable from its mean. In this case, you'll calculate:
Var(Y) = E(Y^2) - [E(Y)]^2.
To find E(Y^2), you'll calculate:
E(Y^2) = 0*0.7 + (1*500)^2*0.2 + (2*500)^2*0.1
Substitute E(Y) and E(Y^2) into the variance formulas to get Var(Y) = 110,000.
So, the expectation and variance of the company's daily loss due to blackouts are $200 and $110,000 respectively.
