Answer:
x = -10
Step-by-step explanation:
verticle angles are congruent
80 + x = 70
Subtract 80 from both sides
x = -10
Answer:
can you provide a picture of the figures? or corresponding lengths?
It would be 2*(5^2)
(2 multiply to (5 rise to the power of 2))
Hope that help.
Since the problem doesn’t give a definite question, here are
the possible questions and answer:
P(fewer than 4 tosses)
= P(one toss) + P(two toss) + P(3 toss)
= (3/4) + (3/4)(1/4) + (3/4)(1/4)^2
= 0.984375
Expected value
= 1 / p
= 1 / (3/4)
= 4 / 3
Variance
= (1 - p) / p^2
= (1 - (3/4)) / (3/4)^2
= (1/4) / (9/16)
= 4 / 9
Standard deviation
= sqrt(Variance)
= sqrt(4 / 9)
= 2 / 3
