Answer:
0.9968
Step-by-step explanation:
Given that:
P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).
1 - p = 1 - 0.5 = 0.5
Number of questions, n = 12
Probability that atleast 2 questions are correct
P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :
Hence,
P(x ≥ 2) = 0.9968
Supplementary angles add up to 180°.
89°= angle 1
x= angle 2
Add the two angles equal to 180°
x + 89= 180
subtract 89 from both sides
x= 91°
ANSWER: The measure of the supplementary angle is 91°.
Hope this helps! :)
Austin would have 6 jelly beans and Alex would have 18 because if Alex were to have three times as many jellybeans as Austin that means Austin will have one times and Alex would have three times which equals four so you would have to divide 4÷24 which gives them six for each group
Answer:
x+3y-6=0
Step-by-step explanation:
given eqn is y=3x-2 which is 3x-y-2=0
the eqn of line perpendicular to given eqn is -x+3y+k=0
it passes through (6,4)
-6+3*4+k=0
or,. -6+12+k=0
or, k= -6
therefore, the eqn of line perpendicular to given eqn is x+3y-6=0
The term in that equation is 3x 7x and -9 hope this helps
