Answer:
Step-by-step explanation:
First you need to find the area then divide that by 14
There are (150 and 3/10) tenths in 15.03 .
Given :-
sam and Bethan shareare in the ratio 5:4 respectively.
Total no of money is = 54ÂŁ
Solution :-
Let Sams share is be x ie = 5
Let Bethans share be y ie = 4
Total no of share is = 9
Therefore the persons share is (particular persons share / total no of share) *
total value of money
Ans : -
Therefore sams share x is = (5/9)* 54 =30ÂŁ
Therefore Bethans share y is = (4/9) * 54 = 24ÂŁ
Answer:
The 90% confidence interval using Student's t-distribution is (9.22, 11.61).
Step-by-step explanation:
Since we know the sample is not big enough to use a z-distribution, we use student's t-distribution instead.
The formula to calculate the confidence interval is given by:
Where:
is the sample's mean,
is t-score with n-1 degrees of freedom,
is the standard error,
is the sample's size.
This part of the equation is called margin of error:
We know that:
degrees of freedom 
Replacing in the formula with the corresponding values we obtain the confidence interval:
Answer:
The third choice: -4, 0, and 1
Step-by-step explanation:
Finding zeroes is another way of saying solve...set the equation equal to zero and solve..
0 = 2x³ + 6x² - 8x
0 = 2x(x² + 3x - 4) (factor out a 2x from all three terms)
0 = 2x(x + 4)(x - 1) (factor x² + 3x - 4)
So
2x = 0 then x = 0
x + 4 = 0 then x = -4
x - 1 = 0 then x = 1
Our zeroes are -4, 0, and 1
