b) (√10-3)+√20*√18
c) 3(√3+1)-2(√3-2)
What is the range for the data set shown?
Answer:
8
Step-by-step explanation:
The highest number in the set is 51 and the lowest number is 43. 51-43=8
Answer and explanation:
To find : Write a fact family for 2, −5, and −10 ?
Solution :
A fact family is a group of math facts using the same numbers.
In the case of multiplication and division, we bring number together to get the product or divisor.
For 2, −5, and −10
The fact family are,
In total, 40 students read either the Internet news or the local paper, but not both; 4 students read both the Internet news and the local paper but not the Campus Observer; and 45 students read either the Internet news, the Campus Observer, or both.
To answer your question, we will use the concept of sets in Mathematics and the principles of the union and intersection of sets. A Venn Diagram can be very helpful in picture this.
(a) How many read the Internet news or local paper but not both?
First, we need to find the total number of students who read either the Internet news or the local paper. This would be the number of students who read the Internet news, plus the number of students who read the local paper, minus the number of students who read both. That would be 24 + 20 - 4 = 40 students.
(b) How many read the Internet news and the local paper but not the Campus Observer?
The answer is given directly in the question. These are the students who read both the Internet news and the local paper, but did not read the Campus Observer, which is 4 students.
(c) How many read the Internet news or the Campus Observer or both?
For this, we add the number of students who read the Internet news to those who read the Campus Observer, and subtract the number of students who read both. This gives us 24 + 29 - 8 = 45 students.

Answer:
Step-by-step explanation:
Part 1
(a) How many read the Internet news or local paper but not both?
There are 25
students who read the Internet news or local paper but not both.
Part 2
(b) How many read the Internet news and the local paper but not the Campus Observer?
There are 3
students who read the Internet news and the local paper but not the Campus Observer.
Part 3
(c) How many read the Internet news or the Campus Observer or both?
There are 65
students who read the Internet news or the Campus Observer.
The slope of the line represented by this equation is 4/5.
We know this because this line is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept. Thus, we can conclude that the slope is 4/5, which means that for every 4 units the line moves up, it also moves 5 units over (because slope is defined as rise/run).
Hope this helps!
