The fraction of his farm which isn’t ruined is 11/18
<h3>Fractions and proportion</h3>
Fractions are written as a ratio of two integers. The given question will be solved using the method of proportion.
If Uncle Bill has planted fruits in the farm and 7/12 is watermelon, and 2/3 of the watermelon section is ruined from the storm, the fraction ruined from the storm is;
Fraction ruined from the storm = 2/3* (7/12)
Simplify to its lowest term to have:
Fraction ruined from the storm = 7/18
Determine the fraction of the firm that is not ruined
Fraction not ruined = 1 - 7/18
Fraction not ruined = 11/18
Hence the fraction of his farm which isn’t ruined is 11/18 if uncle Bill has planted fruits in the farm and 7/12 is watermelon.

Answer:
<u>x=3</u>
Step-by-step explanation:
Addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
3x-7=2
add 7 both sides of an equation.
3x-7+7=2+7
simplify.
3x=9
divide by 3 both sides of an equation.
3x/3=9/3
simplify.
9/3=3
3*3=9
9/3=3
<u>x=3 and 3=x</u>
Hope this helps!

The exact value of the cone is the answer corresponding with B
Answer:
a. The multiplication of these probabilities is justified because the inspections are isolated or don't have the same goal. For instance p1, would mean that not all the planes are checked, p2 that not all the parts in the plane are checked, and p3, that even if the the part where the crack could be inspected, people checking it could not notice it or it could be not identified easily.
b. As the events are independent and there are only two possible answers (detect the plane or not), a binomial distribution could be applied, therefore:
p=0.9*0.8*.5=36 (probability of detecting the crack)
n=3 (number of possibilities, in this case number of planes)
The probability in a binomial formula is given by

Considering that the only possibility that is not being asked is the one of not detecting any crack which would mean x=0, then, we could find the probability as
=1-

Probability is then 0.737856
Step-by-step explanation:
The first one simplifies to 81a^4b
Sorry, I cannot solve the second one without placement of parentheses on the exponents
