In this case, we have three groups which their various reaction time to caffeine is to be tested using the same testing method (amount of caffeine). Hence the appropriate test to use here is the one-way ANOVA
Answer:
The rate of this account corresponds to a increse of 25%.(Option 4)
Step-by-step explanation:
To find out the increase/decrease rate, first we need to re express the exponential term:
V=750*(0.80)^-x
By applying the respectives properties we can express the exponent of the equation as follows:
(0.80)^-x = 1/(0.8^x) = (1^x)/(0.8^x) = (1/0.8)^x = 1.25^x
Then the Kalani's stock investments can be written as:
V=750*1.25^x
Then the above equation can be expressed as:
V=750*(1+0.25)^x
Where 0.25 represents a increment rate of 25%
Answer:
54289
Step-by-step explanation:
233^2
I knew the last digit had to be a 3 because the last number is 9 and the number had to be less than 300 because that is 90000 so I just used trial and error to get the answer.
