Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean 
= 56
The formula for calculating the standard error can be expressed as:
S.E = 2
Therefore, the standard error of the mean = 2
Answer:
y = x^2 (x - 2) = x^3 - 2 x^2
dy/dx = 3 x^2 - 4 x
At x = 3 dy/dx = 3 * 9 - 4 * 3 = 15 The slope (gradient) of the curve
s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
Hello There! Shalinda's total is $29.62.
Our first step is to find 18% of $25.10. To do this, multiply 25.10 by 0.18.
25.10 x 0.18 = 4.518 (Which can be rounded up to 4.52)
So, this gives us the tip, but the question is asking what her total is, including the tip. To find her total, add the price before tip and the tip together.
25.10 + 4.52 = 29.62
So, her total with the tip is $29.62! I hope this was helpful, have a great day!
