What is the slope of the line that passes through the points (4, -2)and (24, -17) ? Write your answer in simplest form.
Simora [160]

Answer:

-  \frac{3}{4}

Step-by-step explanation:

\boxed{slope =   \frac{y1 - y2}{x1 - x2}}

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Slope of the line

=\frac{ - 2 - ( - 17)}{4 - 24}  \\  =  \frac{ - 2 + 17}{ - 20}  \\  =  \frac{15}{ - 20}  \\  =  -  \frac{3}{4}

The data set represents the responses of 15 students who were asked how many text messages they send in a day.
Step2247 [10]
The best measure of center for this data set is the median. The reason is because this data set contains an outlier.

An outlier is a number a lot bigger or smaller than the rest of the numbers. 2 is the outlier.

This outlier skews the mean; meaning that it will make the average smaller than what is representative of the actual data.

The median is the number in the middle when listed in order.

54 is the median.

The function f determines the volume of the box (in cubic inches) given a cutout length (in inches). Use function notation to re
Alenkinab [10]

<u>Complete Question</u>

A box is formed by cutting squares from the four corners of a sheet of paper and folding up the sides. However, the size of the paper is unknown!

Answer:

(a)f(0.2)=0.2(l-0.4)(w-0.4)

(b)f(1.3)=1.3(l-2.6)(w-2.6)

(c)f(1.3)-f(0.2)

(d) f(5.6)-f(5.5)

Step-by-step explanation:

Let the Length of the paper =l  (in inches)

Let the Width of the paper =w  (in inches)

Let the length of the cutout square = x (in inches)

  • Base Length of the Box = l-2x
  • Base Width of the box =w-2x
  • Height of the box =x

Volume of the box: f(x)=x(l-2x)(w-2x)

(a)When the cutout length is 0.2 inches.

x=0.2

Volume of the box (in cubic inches) ,

f(0.2)=0.2(l-0.4)(w-0.4)

(b)When the cutout length is 01.3 inches.

x=1.3

Volume of the box (in cubic inches) ,

f(1.3)=1.3(l-2.6)(w-2.6)

(c)If the cutout length increases from 0.2 inches to 1.3 inches.

Change In volume (in cubic inches):

f(1.3)-f(0.2)\\=1.3(l-2.6)(w-2.6)-0.2(l-0.4)(w-0.4)

(d)If the cutout length increases from 5.5 inches to 5.6 inches.

Change In volume (in cubic inches):

f(5.6)-f(5.5)\\=5.6(l-11.2)(w-11.2)-5.5(l-11)(w-11)
