Answer:
Step-by-step explanation:
To write a linear inequalities we use the same guidelines as linear equations. They are written in the form, and or with any other inequality signs.
One line has y-intercept 2 and slope is -5/1 (down 5 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is true but not the equation becasue (0,0) is not shaded.
The other line has y-intercept -4 and slope 3/1 (up 3 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is false and the equation since (0,0) is not in the shaded portion.
Answer:
Class second have higher score and have greater spread.
Step-by-step explanation:
For first box plot
For second box plot
First class has greater minimum value, it means first class has lower grades.
First quartile of both classes are same, it means equal number students in both classes have less than 62 marks.
First class has greater median.
second class has greater third quartile.
Second class has greater Maximum value. It means second class have higher score than first class.
Second class has greater range. It means the data of second class has greater spread.
Second class has greater inter quartile range. It means the data of second class has greater spread.
Therefore, the class second have higher score and have greater spread.
Answer:
Step-by-step explanation:
<u>Use ratios:</u>
- 30/20 = (x + 5)/(36 - 20)
- 3/2 = (x + 5)/16
- 2(x + 5) = 3(16)
- 2x + 10 = 48
- 2x = 38
- x = 19
$90.95 because 85×. 07=5.95 so then you add the sales tax to 85 and you get $90.95
Answer: 54-7n
Step-by-step explanation:
When we talk about mathematical language, the <u>difference </u>between two numbers, quantities or terms is the <u>substraction operation.</u>
For example, the <u>difference</u> between a and b is:
a-b
On the other hand, if we read a numer c <u>times</u> a number n, this means both numbers are multiplied.
For example:
c <u>times</u> n is:
(c)(n)
So, according to the explained above, “the difference of fifty-four and seven times a number n” is:
54-7n
