Answer:
4)x=15
5)137 degrees
6)supplementary
7)complentary
8)neither
Step-by-step explanation:
4) complementary angles sum = 90
so (3*15+30)
45+30=75
angle 1+angle 2=90
angle 1+75=90
90-75=15
angle1=15
5) angle z is a linear angle which means angle43+anglez=180
180-43=137 degrees
6) supplementary angles =180 degrees
53+127=180
so these angles are supplementary
7) complementary angles =90
56+34=90
so these angles are complementary
8) angles are vertical
HOpe this helps plz vote my answer the brainiest if it does!!!
Answer:
Probability (P) (k successes out of n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)
for this problem n=20, p = 1/6(probability of rolling 1 two) is approximately 0.1667
P ( of getting more that 3 two's) = 1 -P(0 two's out of 20 trials) -P(1 two out of 20 trials) -P(2 two's out of 20 trials) -P(3 two's out of 20 trials)
P ( of getting more that 3 two's) = 1 -0.026 -0.104 -0.198 -0.238 = 0.434
My answer is A
Answer:
C
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← where r is the radius
here r = 4, thus
x² + y² = 4², that is
x² + y² = 16 → C
Answer:
110h + 96k
Step-by-step explanation:
This one is false, since A and B are independent events to say the probability of B given A (this is what P(B|A) means) is equal to P(B) and not P(A).
So this is False
