Answer:
Supplementary angles form 180°.
One angle = 152°
Other angle = y°
➳ The measure of its supplementary angle is <u>28</u>°.
D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.
Answer:
4n - 2
Step-by-step explanation:
Greater = 2n
Smaller = 2n - 2
Sum = 2n + (2n - 2)
Sum = 2n + 2n - 2
Sum = 4n - 2
Answer:
47%
Step-by-step explanation:
we are required to find the probability to randomly select from the union of those who own a smartphone only and those who own a smartphone and computer.
an addition of the subsets cover the entire set.
6 + 15 + 26 + 32 + 21 = 100%
let
p(A)= probability of smartphone only
p(B) = probability of smartphone and computer
p(A U B) = P(A) + P(B)
= 15% + 32%
= 47%
Answer - A
standard equation of parabola y^2 = 4*a*x
putting y = 4 and x = 30 inn above equation
we get a = 4/30
so, the parabola equation is y^2 = 16/30*x
