Answer:
The first one is a the second one is b
Step-by-step explanation:
George shouldn't think too far.
He should use the formula for Compound Interest.
Amount in compound interest, A = P(1+ r/100)ⁿ.
Where A = Amount, P = Principal, r is the rate per year, n = number of years.
Note: the expression (1+ r/100) is raised to power n.
From George's problem: P = 750, r = 22, I guess number of years , n = x
A(x) = 750( 1 + 22/100)ˣ
A(x) = 750( 1 + 0.22)ˣ
From your options I can't see an answer. Except the expression of option (A) is actually raised to power x, and not times x as stated in the option.
Answer:
No, 4÷5=0.8, not 1 and 1/4
64, 68, 71, 87, 215, 215
To find the median, we must find put the data set in order from least to greatest.
Great! We already have it like that :)
Now, our median is in between 71 and 87
So, basically, we have to find what the median of 71 and 87 are.
Simply add the two numbers together, and then divide it by 2.
71 + 87 = 158
158 ÷ 2 = 79
So, 79 is your median!
