You can make a table that shows the data that you get, and there you can cross multiply. Or, you can make a graph (x,y) and see ifbit touches the origin, and is a straight line. I hope I helped you! :3

The following numerically ordered sequence of numbers has a mean
Vladimir79 [104]
Median =  middle number

Total ten numbers so 
median =   (17 + b)/2
given median = 18
so
(17 + b)/  2 = 18
17+b = 36
b = 36 - 17
b = 19

Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25

Mean =  (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
Given mean = 17

so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9

answer
a = 9
b = 19

Hey there! :)

Answer:

x = -7/12.

Step-by-step explanation:

Given:

x + \frac{5}{12} = -\frac{1}{6}

Create a common denominator for each term:

\frac{12x}{12} + \frac{5}{12} = -\frac{2}{12}

Disregard the denominator:

12x + 5 = -2

Subtract 5 from both sides:

12x = -7

Divide both sides by 12:

x = -7/12.

Zinc has a density of 0.258 lb/in³ (pounds per cubic inch).
ollegr [7]

For this case we have that by definition the mass is given by:

m = D * V

Where,

  • <em>D: density </em>
  • <em>V: Volume </em>

The volume of a pyramid is given by:

V = \frac {1} {3} * A * h

Where,

  • <em>A: area of ​​the base </em>
  • <em>h: height </em>

Substituting values ​​we have:

V = \frac {1} {3} * (36) * (2.5)\\V = 30

We now calculate the mass:

m = (0.258) (30)\\m = 7.74\ lb

Answer:

he needs 7.74 pounds of zinc

Y=-x/3 -3/2 on a graph
Sladkaya [172]

From the equation the slope is -1/3 and the y-intercept is -3/2. This shows that the intercept must pass through the y-axis at -3/2.

<h3>Equation of a line</h3>

A line is defined as the shortest distance between two points. The formula for finding the equation of a line in slope-intercept form is given as;

y = mx + b

The point sloe form of the equation is given as y-y1 = m(x-x1)

where

  • m is the slope
  • b is the intercept
  • (x1, y1) is any point on the line

Given the equation of graph to plot

y=-x/3 -3/2

From the equation the slope is -1/3 and the y-intercept is -3/2. This shows that the intercept must pass through the y-axis at -3/2.
