For, f(1) = 2-3x =2-3 =-1
and, for, g(1) = | 2-3x | =| -1 | = 1 (The symbol | | determines the abstract value i.e, positive value)

Adjacent angles share a vertex and a side. For EDF, since the vertex is completely unrelated to AEB, it is not adjacent. For DEA, since it shares a vertex (the line BED, and they add up to get it) and shares the line EA, it is adjacent. For GDA, since it clearly does not share a common vertex, it is not adjacent.

Suppose I have an urn with 9 balls: 4 green, 3 yellow and 2 white ones. I draw a ball from the urn repeatedly with replacement.

Mrrafil [7]

Answer:

$E(X_n)=\frac{2(n-1)}{27}$

$E(y)=\frac{14}{9}$

Step-by-step explanation:

From the question we are told that:

Sample size n=9

Number of Green $g=4$

Number of yellow $y=4$

Number of white $w=4$

Probability of Green Followed by yellow P(GY) ball

$P(GY)=\frac{4}{9}*\frac{3}{9}$

$P(GY)=\frac{4}{27}$

Generally the equations for when n is even is mathematically given by

$Probability of success P(S)=\frac{4}{27}$

$Probability of Failure P(F)=\frac{27-4}{27}$

$Probability of Failure P(F)=\frac{23}{27}$

Therefore

$E(X_n)=\frac{n}{2}*P$

$E(X_n)=\frac{n}{2}*\frac{4}{27}$

$E(X_n)=\frac{2n}{27}$

Generally the equations for when n is odd is mathematically given by

$\frac{n-1}{2}$

$E(X_n)=\frac{n-1}{2}*\frac{4}{27}$

$E(X_n)=\frac{2(n-1)}{27}$

b)

Probability of drawing white ball

$P(w)=\frac{2}{9}$

Therefore

$E(w)=\frac{1}{p}$

$E(w)=\frac{1}{\frac{2}{9}}$

$E(w)=\frac{9}{2}$

Therefore

$E(y)=[E(w)-1]\frac{4}{9}$

$E(y)=[\frac{9}{2}-1]\frac{4}{9}$

$E(y)=\frac{14}{9}$

Linda drives 35 miles five days of the week . During one year, she has 10 days of vacation and 10 holidays when she does not dri

Alenkinab [10]

Answer:

1680 miles

Step-by-step Explanation:

There are 52 weeks in a year. Total number of days she is expected to work would be 52 * 5 = 260 days.

Now we know she has 10 vacation days and 10 holidays. This translates 260 - 20 = 240 days

Now if she drives 35miles 5 days of the week, this means she dives 7 miles per day.

The total number of miles traveled is this 240 * 7 = 1680 miles

Suppose f(x)=6x-2 and g(x)= 2x+4. Find each of the following functions.

NikAS [45]

Suppose f(x)=6x-2 and g(x)= 2x+4

a.

(f+g) (x) = 6x - 2 + 2x + 4

(f+g) (x) = 8x + 2

b.

(f-g) (x) = 6x - 2 -( 2x + 4)

(f-g) (x) = 6x - 2 - 2x - 4

(f-g) (x) = 4x - 6
