Apples are $0.68 and peaches are $0.42.
To find these values, we need to write and solve the following system of equations.
6x + 9y = 7.86
4x + 5y = 4.82
Multiply the first equation by 2 and the second by -3.
12x + 18y = 15.72
-12x - 15y = 14.46
Add the equations together.
3y = 1.26
y = 0.42
Sub in 0.72 and solve for x in either equation and you will get x = 0.68.
Answer:
a. 0.76
b. 0.23
c. 0.5
d. p(B/A) is the probability that given that a student has a visa card, they also have a master card
p(A/B) is the probability that given a student has a master card, they also have a visa card
e. 0.35
f. 0.31
Step-by-step explanation:
a. p(AUBUC)= P(A)+P(B)+P(C)-P(AnB)-P(AnC)-P(BnC)+P(AnBnC)
=0.6+0.4+0.2-0.3-0.11-0.1+0.07= 0.76
b. P(AnBnC')= P(AnB)-P(AnBnC)
=0.3-0.07= 0.23
c. P(B/A)= P(AnB)/P(A)
=0.3/O.6= 0.5
e. P((AnB)/C))= P((AnB)nC)/P(C)
=P(AnBnC)/P(C)
=0.07/0.2= 0.35
f. P((AUB)/C)= P((AUB)nC)/P(C)
=(P(AnC) U P(BnC))/P(C)
=(0.11+0.1)/0.2
=0.21/0.2 = 0.31
It would be: 6 1/4 * 1 5/7
= 25/4 * 12/7
= 300/28 = 150/14 = 75/7
In short, Your Answer would be 75/7 or 10 5/7 Pounds
Hope this helps!
Answer: exponential decay and 18%
Step-by-step explanation: Since what is in the parentheses is less than 1, it is exponential decay
