Answer:

D) (70 + 65) + 80

Step-by-step explanation:

70 + (65 + 80) = 215

A) (70 + 65) × (70 + 80) = 135 × 150 = 20,250

B) (70 × 65) + (70 × 80) = 4,550 + 5,600 = 10,150

C) (70 × 65) + 80 = 4,550 + 80 = 5,030

D) (70 + 65) + 80 = 135 + 80 = 215

E) None of the above

HELPPPPP !!! Plzzz <br> Unit 10: circles <br> Homework 2: central angles &amp; arc measures
Zanzabum

Answer:

JL= 127       JML= 233

Step-by-step explanation:

a circle = 360 degrees and you can tell that JML is going to be larger than JL

and because of that 127 the arc with it = the same

then you do 360-127 and you get 233 for JML

If a teacher is trying to prove that new method of teaching economics is more effective than traditional one, he/she will conduc
ANEK [815]

Answer: b) one tailed test.

Step-by-step explanation:

To prove that the new method of teaching economics is better than the traditional one we have make reference to mean score of students (for example) in their past exams.

Let us assume that from past exams, the mean score of students in economics exams has a value of 40.

After trying the new method in teaching, the students did economics exam and have an average of 65, this is obviously and improvement that can only be validated by performing an hypothesis test on the sample mean score.

Because the teacher is trying to prove that her method is better than the traditional, she will have to perform a one tailed test to prove that the mean score of her teaching method (65) is greater than the mean score of the traditional (40).

Due to the fact that she is opting to prove a point in just a single direction ( that her methods brings larger score compared to the traditional) a one tailed test is the perfect option.

Please help me... the perimeter of square WXYZ is 20 units. The coordinates of three of the vertices are W(3,2), X(3,7), and Y(8
Blababa [14]
Okay, so we know that the perimeter of the square is 20. Since a square has 4 equal sides to find the length of one side, 20/4. Each side is equal to five. Look at each of the coordinates and put them respectively into a graph in your mind. w(3,2) (bottom left) x(3,7) (top left) Y(8,7) (top right). Now we know we need to find the bottom right coordinate. Being that both of the coordinates on the left have the same x value we can justify that the coordinates on the right have the same X value also. we can say this same thing for the y coordinate. Since both coordinates on the top of the square have the same Y value, we can justify that the coordinates on the bottom have the same Y value. So taking the coordinates we now are the same, the answer is Z(8,2). We can check his by seeing if the distance if five from each of the adjacent coordinates. If you have any questions comment below.
