Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)? T

Alenkasestr [34]

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation - and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.

2071 Old Q.No.5 Person's coefficient of skewness for a distribution is 0.4 and its coefficient of variation is 30%. If mode is 8

AlekseyPX

Answer:

$Mean = 100$

$Median = 96$

Step-by-step explanation:

Given

$C_v = 30\%$ --- coefficient of variation

$mode = 88$

$Skp = 0.4$

Required

The mean and the median

The coefficient of variation is calculated using:

$C_v = \frac{\sigma}{\mu}$

Where:

$\mu \to$ mean

So:

$30\% = \frac{\sigma}{\mu}$

Express percentage as decimal

$0.30 = \frac{\sigma}{\mu}$

Make $\sigma$ the subject

$\sigma = 0.30\mu$

The coefficient of skewness is calculated using:

$Skp = \frac{\mu - Mode}{\sigma}$

This gives:

$0.4 = \frac{\mu - 88}{\sigma}$

Make $\sigma$ the subject

$\sigma = \frac{\mu - 88}{0.4 }$

Equate both expressions for $\sigma$

$0.30\mu = \frac{\mu - 88}{0.4 }$

Cross multiply

$0.4*0.30\mu = \mu - 88$

$0.12\mu = \mu - 88$

Collect like terms

$0.12\mu - \mu = - 88$

$-0.88\mu = - 88$

Divide both sides by -0.88

$\mu = 100$

Hence:

$Mean = 100$

Calculate $\sigma$

$\sigma = 0.30\mu$

$\sigma = 0.30 * 100$

$\sigma = 30$

So:

Also, the coefficient of skewness is calculated using:

$Skp = \frac{3 * (Mean - Median)}{\sigma}$

$0.4= \frac{3 * (100 - Median)}{30}$

Multiply both sides by 30

$0.4*30= 3 * (100 - Median)$

Divide both sides by 3

$0.4*10= 100 - Median$

$4= 100 - Median$

Collect like terms

$Median = 100 - 4$

$Median = 96$

The given equations are

$2x-3y=-1\cdots(i) \\\\y=x-1\cdots(ii)$

(a) Solution by graphing both the equations:

Graph for both the equations (i) and (ii) are in the figure. The point of intersection of both the graph is the solution of the equations.

From the graph, the point of intersection is (4,3)).

Hence, the required solution is (4,3).

(b) Solution by elimination method:

Equations (ii) can be written as -x+y=-1, now multiply it by 2, we have

$-2x+2y=-2\cdots(iii)$

Add equations (i) and (iii), we have

2x-3y=-1

-2x+2y=-2

__________

$\Rightarrow -3y+2y=-1-2\\\\ \Rightarrow -y=-3\\\\ \Rightarrow y=3.$

Putting the value of y=3 in equation (i), we have

$2x-3\times 3=-1 \\\\\Rightarrow 2x=-1+9=8 \\\\\Rightarrow x=8/2=4$

Hence, the required solution is (4,4).

(c) Solution by substitution method:

Substituting the value of y from equation (ii) to equation (i), we have

$2x-3(x-1)=-1 \\\\\Rightarrow 2x-3x+3=-1 \\\\\Rightarrow -x=-1-4=-4 \\\\\Rightarrow x=4$

Putting the value of x=4 in equation (i), we have

$y=4-1=3$ .

Hence, the required solution is (4,3).
