There are three different hoses used to fill a pool: hose x, hose y, and hose z. Hose x can fill the pool in a days, hose y in b
WARRIOR [948]

Answer:

C) I and III only

Step-by-step explanation:

Let full pool is denoted by O

Days Hose x takes to fill pool O = a

Pool filled in one day x = O/a

Days Hose y takes to fill pool O = b

Pool filled in one day y = O/b

Days Hose z takes to fill pool O = c

Pool filled in one day z = O/c

It is given that

                         a>b>c

a>b>c>d\\\implies x

Days if if x+y+z fill the pool together = d

1 day if x+y+z fill the pool together =O(\frac{1}{a}+\frac{1}{b}+\frac{1}{c})=\frac{O}{d}---(1)

I) d < c

d are days when hose x, y, z are used together where as c are days when only z is used so number of days when three hoses are used together must be less than c when only z hose is used. So d < c

III) \frac{c}{3}

Using (1)

\frac{bc+ac+ab}{abc}=\frac{1}{d}\\\\d=\frac{abc}{ab+bc+ca}\\\\As\quad(a>b>c)\\(ab+bc+ca)\frac{abc}{3ab}\\\\d>\frac{c}{3}

Similarly

\frac{bc+ac+ab}{abc}=\frac{1}{d}\\\\d=\frac{abc}{ab+bc+ca}\\\\As\quad a>b>c\\(ab+bc+ca)>3bc\\\\d=\frac{abc}{ab+bc+ca}

So,

\frac{c}{3}

For red peppers lets say R, and for green, let's say G.

So R+G=7

Since he has 3 MORE red peppers than green peppers, R would become (G+3)

Lets rewrite the equation.

G+3+G=7, 2G+3=7 , 2G=4, G=2

Since Nate hase 2 green pepper, he would have 3+2 red peppers.

Nate has 5 Red Peppers

deff fn [24]

Answer:

Midrange = 85 (Approx.)

Step-by-step explanation:

Given:

72 143 52 84 100 98 101 120 99 121 86 60 59 71 125 130 104 74 83 55 169

Find:

Midrange

Computation:

Number of data = 21

Midrange = [72 + 143 + 52 + 84 + 100 + 98 + 101 + 120 + 99 + 121 + 86 + 60 + 59 + 71 + 125 + 130 + 104 + 74 + 83 + 55 + 169] / 21

Midrange = 1,786/21

Midrange = 85 (Approx.)
