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
M∠1 = 45°
m∠2 = 135°
m∠3 = 135°
m∠4 = 135°
m∠5 = 45°
m∠6 = 90°
m∠7 = 90°
m∠8 = 90°
m∠9 = 135°
The answer is B. I’m doing this right now at the moment and i have an A in math class so. Good luck! :)
Multiply both sides by 5
r = 35
For the first one the slope is 0.5
For the second one the slope is -1.7
