Find the mode(s). 21 17 15 18 22 16 20

1 answer:

5 0

There is no mode because the mode represents the most frequently occurring value in a data set. A data set may have more than one mode. It is one of the measures of central tendency.

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),

astraxan [27]

Answer:

$k = 1$

Step-by-step explanation:

Given

$3y = 5x + k$

Opposite points: $(1,-2)$ and $(-2,1)$

Required

Find k

First, calculate the midpoint of the opposite points.

$(x,y) = 0.5(x_1 + x_2,y_1 + y_2)$

This gives:

$(x,y) = 0.5(1 -2,-2 + 1)$

$(x,y) = 0.5(-1,-1)$

Open bracket

$(x,y) = (-0.5,-0.5)$

The equation $3y = 5x + k$ becomes:

$3 * -0.5 = 5 * -0.5 + k$

$-1.5 = -2.5 + k$

Solve for k

$k = 2.5-1.5$

$k = 1$

How do you translate the graph of f(x) = x3 left 4 units and down 2 units? Identify the equation of the graph

Marina CMI [18]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

$f(x)=x^3$

The translation of a function is defined as

$g(x)=f(x+a)+b$

If a>0, then the graph of f(x) shift a units left and if a<0, then the graph of f(x) shift a units right.

If b>0, then the graph of f(x) shift b units up and if b<0, then the graph of f(x) shift b units down.

It is given that the graph of f(x) shifts 4 units left and 2 units down. So, a=4 and b=-2.

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

$g(x)=(x+4)^3-2$ $[\because f(x)=x^3]$

$y=(x+4)^3-2$

Therefore option B is correct.
