Answer: Using Chi-square.
Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.
If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.
However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.
Answer:
1900
Step-by-step explanation:
let the deposit amount=x
interest=4%
total percent =100
after adding interest percentage=100+4=104%
X x 104/100=1976
x=1976 x 100/104=1900
Answer:
45 because you have to take 540 divided by 12 to get how many miles there are in one hour
Step-by-step explanation:
Hope it helps
For this case, the first thing we must do is define a variable.
We have then:
p: rate in miles per hour for the last 1.5 hours
We now write the equation that models the problem.
We have then:
Rewriting we have:
From here, we clear the value of p.
We have then:
Answer:
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.
Ok i’ll try to help
split the prism into two rectangle, one 5ft by 3ft and one 3ft by 2ft
multiple 5 and 3 to find the area of the first rectangle
5x3=15
then multiple 3 and 2 to find the area of the second rectangle
3x2=6
add up 15 and 6 to find the area of the total figure
your answer should be 21
hope this helped!!
