balandron [24]

Answer:

3 treatment conditions were compared in the study.

14 individuals participated in the study.

Step-by-step explanation:

Consider the provided information.

Part (A) How many treatment conditions were compared in the study?

There are two sets of degrees of freedom; one for the numerator and one for the denominator.

F ratio is defined as: $df=(df_{\text{Between treatment}}, df_{error})$

The formula for between treatment is: $df_{\text{Between treatment}}=k-1$

Substitute $df_{\text{Between treatment}}=2$ in above formula.

$2=k-1$

$k=3$

Therefore, 3 treatment conditions were compared in the study.

Part (B) How many individuals participated in the study?

The error degree of freedom is $df_{error}=(k-1)(n-1)$

Substitute $df_{error}=26$ and k=3 in above formula.

$26=(3-1)(n-1)$

$26=2(n-1)$

$14=n$

Hence, 14 individuals participated in the study.

If f and g are continuous functions with f(0) = 2 and the following limit, find g(0). lim_(x->0)[2 f(x) - g(x)] = -3

ladessa [460]

We have by distributivity of limits over sums, and continuity of $f(x)$ and $g(x)$ , that

$\displaystyle \lim_{x\to0} \bigg(2f(x) - g(x)\bigg) = 2 \lim_{x\to0} f(x) - \lim_{x\to0} g(x) = 2 f(0) - g(0)$

Given $f(0)=2$ , it follows that

$2^2 - g(0) = -3 \implies g(0) = \boxed{7}$

When 200 gallons of oil were removed from a tank, the volume of oil left in the tank was 3/7 of the tank's capacity. what was th

ki77a [65]

Answer:

Step-by-step explanation:

"When 200 gallons of oil were removed from a tank" algebraically looks like this:

V - 200.

"...the volume of oil left in the tank was 3/7 of the tank's capacity" algebraically looks like this:

3/7(V)

Therefore, the equation is

V - 200 = 3/7(V)

Begin by multiplying both sides by 7:

7(V - 200) = 3V and

7V - 1400 = 3V so

-1400 = -4V so

V = 350 gallons

That's if the volume of the oil in the tank was 3/7 of the tank's capacity.

For the other part of the problem, we set up the equation almost the same, except the 3/7 is a 1/2:

V - 200 = 1/2(V)

Multiplying both sides by 2 gives you

2(V - 200) = V and

2V - 400 = V so

-400 = -V so

V = 400

एउटा आयताकार चाउरको परिमिति 1004 m भए सो चउरको

frez [133]

Answer:

502m

Step-by-step explanation:

let x and y represent the length and breadth of rectangular meadow respectively.

Given,

Perimeter of the meadow =1004m

or,2(l+b)=1004m

or2(x+y)=1004m

orx+y=1004m/2

or,x+y=502m

i.e sum of length and breadth
