Answer:
0.1463
Step-by-step explanation:
Number of observations = 10
Sample mean = 10.5
Sum of standard deviation = 264.5
X = 14
We are to calculate The leverage statistic for study hour 14 using the data above
= 1/10 + (14-10.5)²/264.5
= 1/10 + 3.5²/264.5
= 0.1 +12.25/264.5
= 0.1+0.04631
= 0.1463 is the leverage statistic for the study
Answer: x=120°
Step-by-step explanation:
What you are looking for is the value of the exterior angle of the regular polygon.
For a n-sided regular polygon, the external angle is given by the formula 360°/n.
Because the shape in this example is a regular triangle, the value of n is 3.
360°/n
=360°/3
=120°
Therefore, x=120°
Answer:
A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.”
The input values make up the domain, and the output values make up the range.

Answer:
7
Step-by-step explanation:
We need to plug in -1 for x. Here's what we get:
multiplying two negative numbers gives us a positive number
= 7
Answer: f'(x) = - cos^2(sin(x^2))
Step-by-step explanation:
Derivative of:
f(x) = Sin^2(cos(x^2))
f'(x) = cos^2(-sin(x^2)
f'(x) = - cos^2(sin(x^2))
