Answer:

Mean= Summation /number of terms

= 48/8

=6.

Median

To do this

arrange all terms from smallest to biggest

That is

2,4,4,5,7,8,9,9

The two middle numbers are

5 and 7.

To get the median

add both and divide by 2

5+7 = 12... 12/2 =6

Median=6

Mode.... This is the number that appears most

Mode = 4 and 9.(Bimodal) Both appear equally.

Range: Highest - Lowest

= 9-2 =7.

Answer:

mean = 6 median = 6 mode 9 and 4 range = 7

Step-by-step explanation:

mean = 2+4+4+5+7+8+9+9÷ 8 = 6

median = 5+7÷2

mode = 9 and 4

range = 9-2=7

If v = 6i + 3j, what is ||-10v||
tia_tia [17]

The values of ||-10v|| is 51.96 units

  • Complex numbers are square roots of negative numbers. They are expressions that consist of both the real and imaginary axis.

  • The general form of a complex number is expressed as z = x + iy

Given the complex number v = 6i + 3j,

10v is expressed as 10(6i + 3j)

10(6i + 3j) = 60i + 30j

Take the modulus of the complex number:

|10v|=\sqrt{60^2+30^2}\\|10v|= \sqrt{1800+900}\\|10v|= \sqrt{2700} \\|10v|=51.96units

Hence the values of ||-10v|| is 51.96 units

How does the graph of g(x)=2⌈x⌉ differ from the graph of f(x)=⌈x⌉?
andrezito [222]

Answer:

B is the Answer.

Step-by-step explanation:

A transformation of a function can be represented by

a(bx - h) + k

where a is the vertical stretch or compression, b is the horizontal stretch or compression. H is the shift horizontally and k is the shift vertically.

The new function has a 2 instead of 1 on the orginally function. The function will stretch since 2 is greater than 1.

B is the answer.
