Answer:

Step-by-step explanation:

→ We go up the y axis to 6 and read of the x coordinate which is 4. This is because an inverse function does the the opposite i.e. if f ( x ) = y

f⁻¹ ( y ) = x.

8.4.49 A cow is tethered to one corner of a square barn, 19 feet by 19 feet, with a rope 160 feet long. (See the illustration

SashulF [63]

Answer:

$20096 ft^2$

Step-by-step explanation:

We are given that

Length of rope=l=160 feet

Radius of quadrant of circle=r=160 feet

We have to find the maximum grazing area of the cow.

We know that

Area of quadrant of circle= $\frac{1}{4}\pi r^2$

Where $\pi=3.14$

Using the formula

Area grazed by cow= $\frac{1}{4}\times 3.14(160)^2$

Area grazed by cow= $20096 ft^2$

What value represents the number of ways in which the expected classes are free to vary in the chi-square goodness-of-fit test?

Ket [755]

In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.

The number of independent ways by which a dynamic system can move, without violating any constraint imposed on it, is called number of degrees of freedom. In other words, the number of degrees of freedom can be defined as the minimum number of independent coordinates that can specify the position of the system completely.
