Write a statement using ratio language that can describe A part two whole ratio 7:10

The first quartile is 4.5.

The third quartile is 27.5.

A quartile divides data into three points: lower, middle, and upper quartiles, resulting in four groupings of the dataset. The lower quartile, or first quartile, is designated as Q1 and is the 9 halfway number between the dataset's lowest and median values. The median is also in the second quartile, Q2. The upper or third quartile, abbreviated as Q3, is the center point of the distribution that sits between the median and the highest value.

In the question, we are given the number of incidents in which police were needed for a sample of 9 schools in Allegheny County is 8, 39, 6, 12, 45, 16, 3, 0, 15.

We are asked to find the first and the third quartile for the data.

We first arrange the data in ascending order as follows:

0, 3, 6, 8, 12, 15, 16, 39, 45.

We have 9 data points.

Thus, the first quartile is the data at the point (9 + 1)/4 th observation,

or, the first quartile is the data at the point 2.5th observation,

or, the first quartile is the data at the average of 2nd and 3rd observation, = ( 3 + 6 )/2 = 4.5.

Thus, the first quartile is 4.5.

Thus, the third quartile is the data at the point 3(9 + 1)/4 th observation,

or, the third quartile is the data at the point 7.5th observation,

or, the third quartile is the data at the average of 7th and 8th observation, = ( 16 + 39 )/2 = 27.5.

Thus, the third quartile is 27.5.

Answer

The questions just asking to evaluate y = 8x + 3 for 5 values of x = 2, 4, 6, 8, and 10.

So:

y = 8x + 3

I'd look for a chart with the above values. Make sure that the chart has ALL these values though; I assume that some of the charts, like the one on the picture you sent, have very similar answers.

Step-by-step explanation:

Given 3x - 2 <2x +1 3x -2x 1 + 2 x <3 or x∈(−∞,3)

The lines y=3x−2 and y=2x+1 both will intersect at x=3

Clearly, the dark line shows the solution of 3x−2<2x+1.

Step-by-step explanation:

On the right side, there are

• 2•2 = 4 atoms of Nb

• 2•5 = 10 atoms of O

so among the reactants on the left, the reaction is balanced as

4 Nb + 5 O₂   →   2 Nb₂O₅

Answer:

  -1

Step-by-step explanation:

From the graph, the y-coordinate of the circled point on the y-axis is the value of f(0). (The y-axis has equation x=0.) That coordinate is -1, so f(0) = -1.

__

From the equation, substituting x=0 makes all of the x-terms disappear, leaving only the constant.

  f(0) = -0 +0 -1

  f(0) = -1

Answer:

y=-23/7;y=-19/7;y=-15/7

Step-by-step explanation:

when x is -2 then y is;

2(-2)-7y=19

-4-7y=19

-7y=23 divide both sides by -7

y=-23/7

when x=0 then y is;

2(0)-7y=19

-7y=19

y=-19/7

when x=2 then y is;

2(2)-7y=19

4-7y=19

-7y=15

y=-15/7

Answer:

slope is 11

Step-by-step explanation:

so y = 11x + 62

I used the point slope form to get the y intercept

Hello !

Answer:

[tex]\boxed{ \begin{gathered} \sf \star\ \ y=11x+62 \\ \sf\star\ \ Slope : 11\\\sf \star\ \ y-intercept: 62 \end{gathered}}[/tex]

Step-by-step explanation:

The line pass through the two following points :

The slope-intercept form of a line is of the form [tex]\sf y=mx+b[/tex] where m is the slope and b is the y-intercept.

We're looking for the two coefficients m and b.

Let's replace x and y with their values :

[tex]\begin{cases}\sf 7=-5m+b \\\sf -4=-6m+b\end{cases}[/tex]

We get a system of two equations to solve.

Let's subtract the second line from the first one and solve for m :[tex]\sf 7-(-4)=-5m-(-6m)+b-b\\\iff \sf 7+4=-5m+6m\\\iff \boxed{\sf m=11}[/tex]

Let's substitute 11 for m in the first equation :

[tex]\sf 7=-5\times11+b\\\iff \sf 7=-55+b\\\iff \boxed{\sf b=62}[/tex]

The slope-intercept form of the equation is [tex]\sf y=11x+62[/tex].

The slope is 11.

The y-intercept is 62.

Answer:

Step-by-step explanation:

We can find the distance by using the distance formula.

d= √(x2-x1) ² + (y2-y1)²

For points (x1 = 2, y1 = -6) and ( x2 = -3, y2 = 6)

d= √(-3-2)² + (6 -(-6))², add and subtract what is inside of the parenthesis

d= √(-5)² + ( 12)², square the positive and negative number and get a positive

d= √25 + 144, add the numbers under the square root

d = √169, use the fact that 13*13= 169 to solve the square root

d= 13
