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)
a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class
c
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
d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

The value of x is 60°
Step-by-step explanation:
For a given Straight Line
We know that, The straight angle is an angle equal to 180°
So,
3x = 180
Divide by 3 from both side
3x/3 = 180/3
x = 60°
Thus, The value of x is 60°

B.
68°
C.
67°
D.
78°
Answers
Answer:
B. 68
Step-by-step explanation:
180-112 = 68
just simple angle addition
crossin my fingers and hoping this helps
The measure of the reference angle for a 122° angle is 68°.
What is Reference Number?Reference number associated with t is defined as the shortest distance from the x axis to the terminal point t, along a unit circle.
So we have to find the shortest angle that the X axis make with the angle 112 degree.
112 degree lies on the second quadrant.
We know that,
Sum of the angles along the X axis = 180°
Reference angle of 112 degree = 180° - 112°
= 68°
Hence the reference angle for 112 degree is 68 degrees.

X=4
Answer:
B. x = 4
Step-by-step explanation:
The two triangles have two congruent sides and a congruent angle. You can say ΔBAC ≅ ΔEDF because of SAS. Corresponding parts of congruent triangles are congruent, so you can say:
BC = EF
And we can substitute their values:
6x - 1 = 23
6x = 24
x = 4

What’s the (0,0) and how did I get there
Answers
Answer:
(6, -6)
Step-by-step explanation:
Let's do a process of elimination. Multiply the 2nd equation by 3 so system of equations will now look like this:
x - 3y = 24
9x + 3y = 36
Add these two together to get rid of the y terms and we get
10x = 60 or x = 6
Substitute this value of x into either equation and you will get
3(6) + y = 12 ---> y = -6
