Answer:
chisquare = 31.667
degree of freedom = 2
Step-by-step explanation:
Formula for chisquare test = (O-E)²/E
total number observations= 60 + 25 + 15 = 100
Estimated E,
80% x 100 = 80
15%x100 = 15
5% x 100 = 5
chisquare =

= 5 + 6.67 + 20
= 31.667
from the calculation above the value of the chisquare statistic = 31.67
the degree of freedom is the number of samples in the test n - 1
= 3-1
= 2
I have solve this question also in a tabular form to aid understanding in the file i uploaded.
thank you and good luck!

<h3> What is the polar equation?</h3>
A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as

Therefore the polar equation will be

Answer:
A
Step-by-step explanation:
f = 1/2s
Let s = 2 that means f = 1 That means for 2 cups of sugar there is 1 cup of flour.
This point must be on the graph
It is on A, not on B, not on C
We have to find the output values for the given input values of the function given as,
Here, x = Input value of the function
And f(x) = Output values
By substituting the input values of x as,
For x = -4,
f(-4) = -4(-4) - 5
= 16 - 5
= 11
For x = 1,
f(1) = -4(1) - 5
= -4 - 5
= -9
For x = 3,
f(4) = -4(3) - 5
= -17
For x = 11,
f(11) = -4(11) - 5
= -44 - 5
= -49
Therefore, Option (A) will represent the output values for the given input values.
