Ok to start you have to put
2+-1/9 - 4+-1/3
what exactly is the question because without the proper info. nobody is going to be able to figure it out.
Answer:
x>9 and x<11
Step-by-step explanation:
The mean of the set of numbers that are given in this situation regarding the population will be 1809.33.
<h3>How to solve the mean</h3>
The mean of the numbers will be:
= (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890) / 6
= 1809.33
The median of the numbers will be:
= (1735 + 1890) / 2
= 1812.50
Also, from the complete question, the first quartile will be 1690 and the third quartile is 1935.

Answer:
(a) A = 700×1.015^t
(b) 36.2 years
Step-by-step explanation:
(a) Each year, the account value is multiplied by (1 + 1.5%) = 1.015. Repeated multiplication is signified using an exponent. In t years, when the account has been multiplied by 1.015 t times, the account value will be ...
A = $700×1.015^t
__
(b) You want to find t when A=$1200. Logarithms are involved.
1200 = 700×1.015^t . . . . use 1200 for A
1200/700 = 1.015^t . . . . . divide by 700
log(12/7) = t×log(1.015) . . . . . take logarithms
log(12/7)/log(1.015) = t ≈ 36.2 . . . . divide by the coefficient of t
It will take about 36.2 years for the account balance to reach $1200.
