All you have to do is divide by the same number for both so on this one it's 11 so it's 1/6
Answer:
The correct answer is option (C)-0.245 = 2.160(0.205)
Step-by-step explanation:
Solution
Given that:
The slope = - 0.245
The size sample = n = 15
The standard error = 0.205
The confidence level = 95
The Significance level= α = (100- 95)% = 0.05
Now,
The freedom of degree = n-2 = 15 -2= 13
Thus,
the critical value = t* = 2.16
By applying Excel = [TINV (0.05, 13)]
The Margin of error is = t* (standard error)
=2.16 *0.205
= 0.4428
Answer:
-74
Step-by-step explanation:
f(x) = -2x^2 +8x -10
Let x = -4
f(-4) = -2 ( -4)^2 +8(-4) -10
= -2(16) -32-10
= -32 -32-10
= -74
Option 2. The equation of the parabola is given as y = one eighthx² + 5
<h3>How to read the graph</h3>
We have the coordinate plane to be passing through the graph at point C on the y axis. This is used to represent the slope.
Hence the slope is 5
The equation of the line is given as y=x²+C
Hence we can see that there is a rising slope. So the answer is Option 2.

To reflect the function across the x axis, we must multiply the whole thing by -1
f(kx) is the answer to make the thing negative
so you should result with
f(x)=-x^2
basically the answer is D
