Step-by-step explanation:
Given:
A farmer has a basket of peaches. He gives ⅓ of the peaches to one person, ¼ to another, ⅕ to another, ⅛ to another, and then gives 7 peaches to a 5th person.
Remaining peaches = 4
We need to find the original number of peaches in the basket.
The farmer gives the total number of peaches =
Let x be the former gives the total number of peaches
We multiply and divide by 120 in right side of the above equation because of 120 is divided by all given denominator and then simplify.
We add the remaining peaches by given peaches for the original number of peaches in the basket.
Original number of peaches =
Original number of peaches =
Original number of peaches =
Original number of peaches =
Original number of peaches =
Therefore the original number of peaches in the basket is or
Answer:
a) 0.172
b) 0.167
c) 0.1404
Step-by-step explanation:
Margin of error, E =
here,
p = probability of the event
n = sample size
a) n = 30
p = 10 ÷ 30 = 0.333
Therefore,
E =
= 2 × 0.0861
= 0.172
b) n = 30
p = 21 ÷ 30 = 0.7
Therefore,
E =
= 2 × 0.0836
= 0.167
c) n = 30
p = 22 ÷ 50 = 0.44
Therefore,
E =
= 2 × 0.0702
= 0.1404
Answer:
x=
Step-by-step explanation:
you might need a calculator to get the answer but since it is a right triangle the legs of the triangle in this case x and the are the same length
