The legs of a right triangle measure 6 inches and 12 inches what is the area fo the triangle

Answers

Answer: 36

Step-by-step explanation:

The area of a triangle is (1/2)lw <- that just means that a triangle is half a square. Length * width is the original formula for solving the area of a square.

6 * 12 = 72; 72/2 = 36

36 because the triangle formula is half of base times height. Base times height would be 72 so half of that is 36

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points) Yes, it is a valid inference because his classmates make up a random sample of the students in the school
Yes, it is a valid inference because he asked all 26 students in his science class No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Answers

Answer:

Option D is the correct answer.

Step-by-step explanation:

Given scenario is :

Johnny wants to know how many students in his school enjoy watching science programs on TV.

He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV.

He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV.

No, this is not a valid inference as Johnny has asked the question to only his classmates. This does not denote the whole population of the school.

Therefore, the correct option is - No, it is not a valid inference because his classmates do not make up a random sample of the students in the school.

No is it not valid because that is only the kids in his class, not the whole school

What is the LCD of 2/3, 4/5, and 7/10?
A.30
B.18
C.15
D.10

Answers

The Prime Factorization of 3,5,10 is:

3 = 1 x 3
5 = 1 x 5
10 = 2 x 5

Lets Multiply it:
We already have a 5, so we can only use one of the fives.

1 x 1 x 2 x 3 x 5 = 30

the answer is 30

Does the equation represent a linear or nonlinear function explain 2x+3y=7

Answers

linear, because there is still a slope function (-2/3)

The equation is linear because you can rewrite it in slope-intercept form.
