ERROR ANALYSIS Describe the error in determining whether the lines are parallel, perpendicular, or neither.
Line 1: (3,-5),(2, -1)
Line 2: (0,3),(1,7)
There is a sign error in finding m
The slopes of perpendicular lines are negative reciprocals of each other.
Two lines are parallel when their slopes have the same absolute value.
In Line 2, one point is on the x-axis, so only the y-values should be subtracted to find the slope.

Hillary is making a blanket for her mom. Three fourths of the blanket is green and the rest is yellow. Two thirds of the yellow part has her name on it. What fraction of the blanket will, have her name on it?
Answers
Answer:
1/6
Step-by-step explanation:
Hillary is making a blanket for her mom.
Let the total blanket = 1
Three-fourths of the blanket is green and the rest is yellow.
The fraction for the rest(yellow portion) = 1 - 3/4
The Lowest Common Denominator is 4
Hence,
4 - 3 /4 = 1/4
Two-thirds of the yellow part has her name on it.
The fraction of the blanket that will have her name on it is calculated as
2/3 of 1 /4
= 2/3 × 1/4
= 1/6

Line segment ĀB has endpoints of A(-3,7) ans B(3,15). Identify the slope of a line perpendicular to ĀB
Answers
Answer:
m = -3/4
Step-by-step explanation:
Let's look at how much x and y change as we move from A to B:
x increases by 6, from -3 to 3, and y increases by 8, from 7 to 15. Thus, the slope, m, is rise / run, or (change in y): m = 8/6 = 4/3.
Now any line perpendicular to AB has a slope which is the negative reciprocal of this 4/3: m = -3/4

un campo de futbol tiene 100m de largo y 60m de ancho¿ Cuales son la longitud y la anchura del campo?
Answers
Answer:
328 pies de largo
196.8 pies de ancho
Step-by-step explanation:
Ya que las medidas dadas estan en metros, podemos usar esas medidas para calcular la longitud y anchura en pies.
100 metros de largo.
60 metros de ancho.
Si sabemos que 1m es igual a 3,28 pies, simplemente tenemos que multiplicar las medidas en metros por 3.28 y nos va dar la medida del campo en pies.
100 * 3.28 = 328 pies de largo
60 * 3.28 = 196.8 pies de ancho

A farmer planted corn in a square field. One side of the field measures 37 yards. What is the area of the cornfield
Answers
Answer:
1,369 cm^2
Step-by-step explanation:
A square is a two-dimensional shape with four right angles and four equal sides.
This means each and every side is equal.
In this case, every side is 37 yards.
To find the area of a square, simply multiply a length of a side by itself.
Like this,
37⋅37 = 1,369.
Therefore, the area of the cornfield is 1,369 yards cm^2.

Right triangles 1-2 and 3 are given with all their angle measures and approximate side lengths.
Use one of the triangles to approximate the ratio WY/WX
A. 0.34
B. 0.94
C. 1.06
D. 2.76
Answers
Answer:
0.34
Step-by-step explanation:
Considering the right-angled triangle XYW, an approximate ratio WY/WX is equal to 0.34. The correct option is A.
What is a right-angled triangle?A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangle triangle. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Considering the right-angled triangle XYW, we would apply the law of cosine to approximate the ratio WY/WX. Mathematically, the law of cosine is given by:
cos(θ) = Adj/Hyp
Where:
Adj is the adjacent side of a right-angled triangle.
Hyp is the hypotenuse of a right-angled triangle.
θ is the angle.
Substituting the given parameters into the formula, we have;
cos(θ) = WY/WX
cos(70) = 3.4/10
0.34 = 0.34.
Therefore, the correct option is A.

a football team gains 9 1/2 yards on their first play then lose 10 yards for a penalty they lose 5 yards and then gain 7 yards on the next two plays what is the teams overall gain or loss and did rhey make a first down (10+ yards)?
Answers
Answer: No
Step-by-step explanation: Because if the team lost 10 yards from 9 1/2 then they would be negative yards if they lose 5 yards they will have 5 1/2 and if they gain 7 yards their total will be 1.5 so they never made it to 10+ yards.

Which is the expected value of the random variable with given probability distribution ?
Answers
Answer:
Step-by-step explanation:
Let X be the RV we are talking about.
Expected value has different aliases, such as weighted average, mean, expectation, first moment and so on.
Okay, how do we calculate the average first, just sum all the values and divide by number of values. It comes from the basic assumption, which is choosing one of them is equally likely. What I mean by that is quite simple, above process what I talked about is just sum of the numbers times their probabilities. e.g. (a+b+c+d)/4 = a/4 + b/4 + c/4 + d/4. In the example, we assumed that probability of choosing any a, b, c and d is equally likely.
Then, why I use the term weighted average is the generalized situation of average, which is some of the numbers are repetitive. For instance, X can take the values a, b, c and d; however, X can take the value a 3 times more than d, X can take the value b 2 times more than d and c and d occurs with the same frequency at X, Therefore, if we take a sample, it is likely to be a, b, a, c, d, a, b or the permutation of this sample. Therefore the weighted average is 3 * a / 7 + 2 * b / 7 + c / 7 + d /7 or using normal average theorem (a + a + a + b + b + c +d) / 7. First, both of them are equal. Find the distribution and multiply the values with the probabilities of the distribution and sum them up or just add them and divide by number of sample. Second, if you check that, a has more weight, which means a can determine the direction of the average more. That is the logic behind the expected value.
Now, if X is a discrete RV (like in the above example), we know what we are going to do. What if X is a continuous RV ? X could take infinite values therefore if you divide a number with an infinite value, the probability of an individual value X could take is going to be 0. Therefore, we cannot calculate the expected value of chosen values individually; however, we can calculate the expected value of an interval by approximating with Riemann Sum or with a better choice, using integrals. Because, technically using Riemann Sum and quantizing the values and approximating the area of the curve is the same as we did above.
In conclusion, basically if X is a discrete RV and the values X could take is countably infinite,
If X is a discrete RV and the values X could take is finite,
if X is a continuous RV,
