A graphing calculator can do a linear regression on these points very easily. The y-intercept is 107.
_____
If you want to do this by hand, you can use the 2-point form of the equation for a line, then evaluate for x=0.
.. y = (100 -102)/(35 -25)*(x -25) +102
.. y =-2/10*(0 -25) +102
.. y = 107
OK so the factor of 10 is 1 times 10 and 5 times 2
Answer:
10
Step-by-step explanation:
Answer:
The function f(x) = -9.5 + 6 + x² is neither odd or even.
Step-by-step explanation:
We know that a function is termed as 'even' when
f(-x) = f(x) for all x
We know that a function is termed as 'odd' when
f(-x) = -f(x) for all x
Given the function
f(x) = -9.5x⁵ + 6 + x²
substitute x with -x
f(-x) = -9.5(-x)⁵ + 6 + (-x)²
as (-x)⁵ = -x⁵, so
f(-x) = -(-9.5x)⁵ + 6 + (-x)²
Apply exponent rule: (-a)ⁿ = aⁿ, if n is even
f(-x) = -(-9.5x)⁵ + 6 + x²
Apply rule: -(-a) = a
f(-x) = 9x⁵ + 6 + x²
As
f(-x) ≠ f(x) ≠ -f(x)
Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.
Answer:
0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit
Step-by-step explanation:
We are given the following in the question:
Total number of students, n = 25
Number of student who noticed woman in gorilla suit = 9
Number of student who failed to notice woman in gorilla suit, x = 25 - 9 = 16
We have to find the proportion of the students in the population who failed to notice the woman in the gorilla suit.
Formula:
0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit
