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%
ABC is a isosceles triangle
AC = BC
so
<A = <B
2x - 20 = x + 8. solve for x
subtract x to both sides
2x - 20 - x = x + 8 - x
x - 20 = 8
add 20 to both sides
x - 20 + 20 = 8 + 20
simplify
x = 28
<A = <B = 28 + 8 = 36
<C = 180 - 2(36)
<C = 180 - 72
<C = 108
Answer
B. 108 degrees
Answer:
The answer is 180
Step-by-step explanation:
looking at the line plot, if you go up to the 3 and see where the line intersects with it, you see that it's 180.
To get the number of years it will take for the tuition fee to double we use the compound interest formula, this is given by:
FV=p(1+r/100)^n
where:
FV=future value
p=principle
r=rate
n=years
from the information given, we are required to solve for n given that:
FV=$20,000
p=$10,000
r=7%
thus plugging in the formula we shall have:
20000=10000(1+7/100)^n
solving for n we have:
2=(1.07)^n
introducing natural logs we get:
n=ln2/ln1.07
n=10.25 years
Answer: 10.25 years
Answer: 12
Step-by-step explanation:
13 times 5 = 56
then divide 56 by 2
=12
x^2 +25 =169
Subtract 25 from each side
x^2 +25-25=169-25
x^2 = 144
x = 12
hope this helps :)
