Given
investment = $1200
earned in interest = $ 66
Time = one year
Find out the interest rate .
To proof
FORMULA
here
Principle =$ 1200
Simple interest =$66
Time = 1 year
put these value in the above formula
we get
Rate = 5.5 %
The interest rate is 5.5 %
Hence proved
Answer:
x = 20.4
Step-by-step explanation:
x/0.6 = 17/0.5
0.5x = 17 (0.6)
0.5x = 10.2
0.5x/0.5 = 10.2/0.5
x = 20.4
CHECKING MY WORK:
20.4/0.6 = 34
17/0.5 = 34
34 = 34
Step-by-step explanation:
the expression is (9.6p+7.6)+(8.7p-9.1)+(5.9q+3.8)
24.2p+2.3
Answer:P(male | buys lunch) = 0.4 and P(male) = 0.3.
Step-by-step explanation:
There are 46+176 = 222 males.
There are 254+264 = 518 females.
There are a total of 740 people.
The probability of being male is 222/740 = 0.3
There are 46+254 = 300 people that bring lunch.
There are 176 + 264 = 440 people that buy lunch.
P(male | buy lunch) = 176 / 440 = 0.4
P(male | buys lunch) = 0.4 and P(male) = 0.3.
