Answer:
Step-by-step explanation:
The formula for arc length in terms of degrees is
and we have everything we need to fill in to find the angle measure.
which is the same as
and
and
so
θ = 253°
Answer:
(-4 , 3)
Step-by-step explanation:
(x,y) reflected over y axis ---> (-x,y)
20/28 = 5/7
Step-by-step explanation:
Step 1 :
Total number of students in the algebra class is 28
Given that the number of students who play neither sport = 8
Step 2 :
Probability that a student randomly chosen does not play any sport is obtained by number of students who play neither sport/ total number of students
Hence probability is 8/28
Step 3 :
The probability that a student randomly chosen plays either basketball or base ball = 1 - 8/28 = 20/28 = 5/7
The correct answer is D (x - 5)(x - 2)
You can tell this because in the picture, we are looking for all of the cross sections to multiply to their appropriate boxes. In the bottom right corner, we see the number 10. This means that the bottom number and the right number must multiply to 10. This only happens in A and D, whereas in B and C those equal -10.
To determine between A and D, you must find the ones that have negatives, since the two x values are both negatives. D is the only one with negative numbers out of the ones we are left working with. Therefore, D is the correct answer.
