Write the equation of the cost
p stands for the cost per pear, a stands for the cost per apple
6p + 3a = 3.9
2p + 5a = 3.3
Solve the equation system
To solve the equation system, we work on eliminating variable p so we will find the number of a. To eliminate, we have to change the coefficient of p to the same number (i will change it to coefficient 6)
6p + 3a = 3.9 (multiply 1)
2p + 5a = 3.3 (multiply 3)
---------------------------------
6p + 3a = 3.9
6p + 15a = 9.9
-------------------- - (substract)
-12a = -6
a = -6/-12
a = 0.5
To find the cost per pear, subtitute the number of a to one of the equation
2p + 5a = 3.3
2p + 5(0.5) = 3.3
2p + 2.5 = 3.3
2p = 3.3 - 2.5
2p = 0.8
p = 0.4
The cost of one pear is $0.4
22×16=352 ounces
There are 16 ounces in a pound
Answer:
Probability that an ear of corn selected at random will contain no borers is 0.4966.
Step-by-step explanation:
We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.
Let X = <u><em>Number of borers per ear</em></u>
The probability distribution of the Poisson distribution is given by;
where, 
= parameter of this distribution and in our question it is proportion of bores in the total ears = 
= 0.7
SO, X ~ Poisson( = 0.7)
Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)
P(X = 0) = 
= 
= <u>0.4966</u>
Hence, the required probability is 0.4966.
So there are 20 eggs total.
If Kyla/Kyle found 1/2 the eggs then she/he found 20/2 = 10 eggs
If Kevin found 1/4 of the eggs then he found 20/4 = 5 eggs
Add the two totals 10+5=15
So 15 out of the 20 were found leaving 5 left to find because 20-15=5
Hope this helps!
