Answer:
y = 400(1.01)^t
Step-by-step explanation:
Firstly find the rate
(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)
408.04-404= 4.04
I=(P*R*T)/100
From which R=(100*I)/PT
R= 100*4.04/404*1
R=1%
Using compound interest formula
A =P(1+r/100)^n
where n is time
substituting each value
y = 400(1+1/100)^t
y= 400(1.01)^t
Answer:
graph A is the answer because the M is at the 3 and it move up 5
16 divided by 2 4/5
change 2 4/5 to an improper fraction
2 4/5 = (5*2+4)/5 = 14/5
16 divided by 14/5
copy dot flip
16 * 5/14
rearrange to make the math easier
16/14 *5
8/7 *5
40/7
7 goes into 40 5 times with 5 left over
5 5/7
Answer:
112
Step-by-step explanation:
Answer:
Range is 44
mean is 29.7
variance is 289.56
standard deviation is 17.016
Step-by-step explanation:
The data given as follows
3, 24, 30, 47, 43, 7, 47,13, 44, 39
Range = maximum - minimum
= 47 -3 = 44
mean =
= 297/10 = 29.7
variance =
= 289.56
SD =
= 17.016
The standard deviation of the given data is not a good measure as the range and standard deviation are far apart. The standard deviation gives how the given data is dispersed from the mean or expected value, while the range gives a rough idea of variability of the data.
