Which of the following is the definition of a weighted average?
Group of answer choices

The ratio of the width to the height of a television screen.

a computing error caused by switching two adjacent digits.

an indicator, sign or measure of something.

An average resulting from the multiplication of each component by a factor reflecting its importance.

Step-by-step explanation:

Given:

Find: Z to two decimal places

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {z}^{2} = {y}^{2} \\ {70}^{2} + {z}^{2} = {106}^{2} \\ 4900 + {z}^{2} = 11236 \\ {z}^{2} = 11236 - 4900 = 6336 \\ z = \sqrt{6336} = 79.60[/tex]

Answer:

Start at 4, up 2, right 1

Step-by-step explanation:

Using Y=mx+b

B: begin

M: movement

Start at 4, then move up 2 and right one (because 2 = [tex]\frac{2}{1}[/tex])

Hope this helps! :)

Answer:

y=-2x+5

Step-by-step explanation:

x-2y=2

2y=x-2

y=(x-2)/2

so the slope is 1/2

for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition

(1/2)m=-1

m=-2

the only line with a slope of -2

If is wrong i'm sorry

Step-by-step explanation:

Percent go on 1 side

125

----       125% out of 100%

100

35 next to 125% due to the unknown amount of votes on the other side

P goes under 3 and the answer is A

Answer:

A.

Step-by-step explanation:

125% = 35 votes

100% = p

Answer : A

do the proportion and u get

[tex]\frac{125}{100} =\frac{35}{p}[/tex]  

p = 100*35:125 = 3500:125 = 28

Answer:

9

Step-by-step explanation:

Since 12 divided by 4 is 3, that is the constant. So 3 times 3 is 9

Answer:

12

Step-by-step explanation:

Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.

We know that

a²+b²=c²

Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).

We want to find x, which in this case is c. So,

to solve for c, we get

c=[tex]\sqrt{a^2+b^2 }[/tex]

So, after plugging in the values, we get

[tex]c=\sqrt{10.6^2+6.1^2}[/tex]

[tex]c=12.23\\\\=12 (rounded)[/tex]

[tex]\boxed{ \rm{answer \: by \: { \boxed{ \rm{☆HayabusaBrainly}}}}}[/tex]

x² = (10,6)² + (6,1)²

x² = 112,36 + 37,21

x² = 149,57

x = 12,22mi✔

Answer:

b

Step-by-step explanation:

your right

Answer:

y = -2/3x - 2

Step-by-step explanation:

Picking two points on the line: (0,-2) & (-3,0)

Using the slope formula:

[tex]\frac{x2-x1}{y2-y1}[/tex]

= (0-(-2))/(-3-0)

= 2/-3

= -2/3

y = -2/3x + c

Subsituting (0,-2) into 'y = -2/3x+c':

-2 = 0 + c

c= -2

Hence,

y = -2/3x -2

Hello,There! I'll be glad to help!

what is 4/2/3 x 1/3/7 ?

[tex]6\frac{2}{21}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]4 +\frac{2}{3} + 1 +\frac{3}{7}[/tex]

Solving the whole number parts

[tex]4 + 1 =5[/tex]

Solving the fraction parts

[tex]\frac{2}{3}+\frac{3}{7} =?[/tex]

Find the LCD of 2/3 and 3/7 and rewrite to solve with the equivalent fractions.

LCD = 21

[tex]\frac{14}{21} +\frac{9}{21} =\frac{23}{21}[/tex]

Simplifying the fraction part, 23/21,

[tex]\frac{23}{21} =1\frac{2}{21}[/tex]

Combining the whole and fraction parts

[tex]5 + 1+ \frac{2}{21} =6\frac{2}{21}[/tex]

Hence, The answer is [tex]6\frac{2}{21}[/tex]
