Simple Interest =
Or, Interest =
Or, Interest =
Or, Interest = 19.25 r
Now, Interest = Amount - Principal
So, 19.25 r = $2138.50 - $2100

∴ r =
I.e r = 2
So, rate of interest = r = 2 %
Hence The rate at which the account pay the deposit is 2 % Answer
Answer:
y = x + 5
Step-by-step explanation:
The line passes through points (-7,-2) and (2,7)
Slope of the line = change in y ÷ change in x = = 1
Taking another point (x,y) on the line;
Slope = = 1
Cross multiplying this gives;
y - 7 = x - 2
y = x + 5
Answer:
The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
Step-by-step explanation:
Given that:
The treatment group using Spray A reported a mean of 3.5 mosquito bites.
The treatment group using Spray B reported a mean of 5.6 mosquito bites.
After the data are re-randomized; the differences of the means are shown in the dot plot. The dot plot is attached in the file below;
The best conclusion that can be make based on the data from the dot plot is :
The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
