Answer:
A.0.39 grams
margin of error at 90% confidence intervals is
M.E = 0.39 grams
Step-by-step explanation:
<u>Explanation</u>:-
Given a sample of size n = 25
mean of the sample x⁻ = 15 grams
Standard deviation of the sample 'S' = 1.5 grams
<u>margin of error at 90% confidence intervals is determined by</u>
<u></u>
<u></u>
The degrees of freedom ν = n-1 = 25-1 =24
The tabulated value t₀.₉₀ = 1.318
Margin of error = 0.3954
<u>Conclusion</u>:-
Margin of error at 90% confidence intervals = 0.3954
Answer:
600
Step-by-step explanation:
600 hundred is already rounded.
Say if the number was 650, it would round to 700. But if it was 610 it would round to 600.
Hello from MrBillDoesMath!
Answer:
(3 /2)* ( x^(1/2) )
Discussion:
I think you are asking for the derivative of (3x) ^ (1/2) -- the square root of both 3 and x.
The derivative of (3x) ^ (1/2) is
(1/2) (3x) ^ (1/2 -1) (d(3x)/dx) =
(1/2) (3x)^(-1/2) 3 =
3/2 (1/ (3x)^ (1/2) ) =
3/2 ( 1/ 3^(1/2)) ( 1 / x^(1/2) ) =
(3/3^(1/2)) * (1/2) ( 1/ x^(1/2) ) =
( 3^(1/2) / 2 ) * (1/ x^(1/2) ) =
( 3^(1/2) ) * (1 / 2) * (1/ x^(1/2) ) =
It's straightforward but using a keyboard over complicates its appearance

I calculated it logically
Answer:
Step-by-step explanation:
- x^2+8x-7<0
- x^2 + 8x + 16 - 23 < 0
- (x + 4)^2 < 23
- |x + 4| < √23 ≈ 4.8
