y=3/2x+3 that is the answer
Find r :
C=2πr
280=2(3.14)r
r=280/2(3.14)
r=44.6cm
find area :
A=πr²
A=3.14(44.6)²
A=6246 cm²
Answer : 4)6,246
Okay, so I'm going to try to explain this to the best of my ability.
The angle with measure 41 and 56 have an unidentified angle. We need to figure out what that is, since <x and that angle are vertical and congruent.
Those three angles are adjacent and equal 180 degrees.
41+56+m(missing angle)= 180
97+m=180
Subtract 97 on both sides.
m=83
So, x=83 degrees. Vertical angles are congruent.
I hope this helps!

The probability that it is pink or canvas is 0.9
Step-by-step explanation:
Let us revise the meaning of "or" , "and" on probability
:
- The use of the word "or" means that you are calculating the probability that either event A or event B happened. Both events do not have to happen
- The use the word "and", means that both event A and B have to happen
The addition rules are:
- P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
- P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)
Anna is shopping for a new backpack
∵ The probability that the backpack is pink is 0.7
∴ P(pink) = 0.7
∵ The probability that it is canvas is 0.7
∴ P(canvas) = 0.7
∵ The probability that it is pink and canvas is 0.5
∴ P(pink and canvas) = 0.5
Substitute the values above in the rule below
∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)
∴ P(pink or canvas) = 0.7 + 0.7 - 0.5
∴ P(pink or canvas) = 0.9
The probability that it is pink or canvas is 0.9

Answer:
Jason Inherit a land with a 45% chance of having oil.
Step-by-step explanation:
The probability of the land having oil is = P
(
O)
=
45
/100
The probability of the land having oil is= Q(O
)
=55/100
The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.
The probability of the correct reading is= P(M)=80/100
The probability of the incorrect reading is=Q(M)=20/100
The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present × probability of the incorrect reading
Probability=P(O) x Q(M)
Probability=45/100 x 20/100
Probability=9/100
The probability of the test predicting no oil in land and the land has oil is 0.09 or 9%
