Answer:
$3960
Step-by-step explanation:
Given parameters:
Principal = $12,000
Simple interest = 8.25%
Time = 4yrs
Unknown:
Interest earned = ?
Solution:
To solve this problem, we have to use the simple interest formula shown below:
Simple interest =
P is the principal
R is the rate
T is the time
Now insert the parameters and solve;
Simple interest = = $3960
Answer:
A, D, & E
Step-by-step explanation:
4 x 3 = 12
2 x 6 = 12
3 x 4 = 12
What Ratio table??? There is no pic
Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
You can find the slope of the two points with the following formula:
Substitute the corresponding values into the equation.
<u>The slope of the line is 2.</u>
