Answer:
s = 35pi units
We can either leave it with pi in the answer or approximate
s= 109.9557429 units
Step-by-step explanation:
Arc length is found by
s = r * theta where r is the radius and theta is given in radians
Changing the angle from 150 degrees to radians by multiplying by pi/180
150 *pi/180 = 5/6 pi
Now we can use the formula
s = 42 * 5/6 pi
s = 35pi
We can either leave it with pi in the answer or approximate
s= 109.9557429 units

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

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.

to find the answer, first find all of the factors of 30
then, find the perimeter if those two were the two lengths of the rectangle...
until you find a pair of side lengths that make the perimeter = 34
To begin...
1 and 30 --> A=30; P=62 X
And so on
Hope this helps!

Answer:
(x^2+11)(x^2-11)
Step-by-step explanation:
You didn't list the options, but it should be:
(x^2 + 11) (x^2 - 11)
We use this formula: a^2 - b^2 = (a + b) (a - b)

Did you say he can choose " 1 snack " ?
Well then. There are 9 different items in the box, so he has
9 different choices of snack.
I guess that means he can choose his snack in 9 ways.
