Answer:

b. can be larger, smaller, or equal to the number of degrees of freedom for the denominator.

Step-by-step explanation:

The distribution of all possible values of the f statistic is called an F distribution with various degree of freedom. For an F distribution, the F statistic is greater than or equal to zero and as the degrees of freedom for the numerator and for the denominator get larger, the curve approximates the normal.

For an F distribution, the number of degrees of freedom for the numerator can be larger, smaller, or equal to the number of degrees of freedom for the denominator.

F(x)=2/3x+9x<br> What is the value of f(12)?
andreev551 [17]

Answer:

116

Step-by-step explanation:

To find f(12), plug in 12 as x in the equation:

f(x) = 2/3x + 9x

f(12) = 2/3(12) + 9(12)

f(12) = 8 + 108

= 116

So, f(12) = 116

25. Save the simultaneous equations 2x-y=4;x+y=5​
Gnoma [55]

Answer:

Step-by-step explanation:

2x-y=4 ..........(1)

x+y=5 ...........(2)

<u>Add equation 1 and 2:</u>

We get:

3x=9

x=9/3

x=3

Substitute value of x in (2):

x+y=5

3+y=5

y=5-3

y=2

In ΔQRS, the measure of ∠S=90°, the measure of ∠R=31°, and QR = 46 feet. Find the length of SQ to the nearest tenth of a foot.
ss7ja [257]

Answer:

SQ=23.7\ ft

Step-by-step explanation:

we know that

In the right triangle QRS

sin(R)=\frac{SQ}{QR} ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

sin(31^o)=\frac{SQ}{46}

solve for SQ

SQ=\frac{SQ}{46}sin(31^o)=23.7\ ft
