5) Lets use x for the unknown middle side. Since all the sides have to equal to perimeter, we can set everything equal 43.
(x-3)+x+(2x-2)=43
That would be your equation.
6) Knowing what we know from the previous problem, we can set the equation to 27.
(x-3)+x+4(x-3)=27 (we can plug in x-3 to represent the first side)
7) Since all the sides have to equal to perimeter, we can set everything equal 25.
a=2b-2
c=b+3
(2b-2)+b+(b+3)=25
Answer:
5.35*2+x=16 and the answer is $.35
Step-by-step explanation:
5.35*2+x=16
10.70+x=16
-10.70 -10.70
x=5.30
5.30/15= about .35
To increase sales, an online clothing store began giving a 50% off coupon to random customers Six customers each made purchases from the website the binomial random variable and mean and standard deviation of X is mathematically given as
x= 0.9798
<h3>What is a binomial random variable?</h3>
Generally, the equation for is mathematically given as
P(coupon) = 1/5
P(coupon)= 0.2
the binomial distribution
Therefore, The mean and standard deviation of X
x= 0.9798
In conclusion, mean and standard deviation of X
x= 0.9798

Answer:
R = 35l-215
Step-by-step explanation:
total amount they earn = 35l
however, to account for the money used to rent the machines, we have to deduct 215 from the total cost.
hence,
<u>R= 35l-215</u>
total amount they raised = 35(26)-215 = <u>$695</u>
they would lose <u>$215</u> if they were unable to aerate due to weather conditions
they could avoid this potential loss by <u>checking the weather report before renting the machines</u>
