Out of the 180 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 of those students also signed up for canoeing.Use a two-way table to organize the information and answer the following question:
Approximately what percentage of students signed up for neither canoeing nor trekking?
72%
40%
54%
98%
Answers
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
Total number of students = 180
Number of students who signed for canoeing (C) = 72
Number of students who signed for trekking (T) = 23
Number of student who signed for trekking is also signed for canoeing = 13
Number of students who only signed for canoeing (C) = 72-13=59
Number of students who only signed for trekking (T) = 23-13=10
So, Number of students who signed up either for canoeing or trekking is given by
So, Number of students who signed up neither for canoeing not trekking is given by
So, Percentage of students signed up for neither canoeing nor trekking is given by
Hence, Third option is correct.

Answer:
The answer to your question is 250 - 20 < 80 + 15x
Step-by-step explanation:
Data
Beth has 250 books and sells 20 each week
Martin has 80 books and sells 15 each week
week = x
Process
1.- Write an equation for each situation
Beth 250 - 20x
Martin 80 + 15 x
2.- Write the inequality
250 - 20 < 80 + 15x

Answer:
Step-by-step explanation:
These binomials make up the difference of squares.
3x * 3x = 9x^2
3x * 5 = 15x
-5 * 3x = - 15x
-5 * 5 = - 25
Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with
9x^2 - 25

Answer:
y = 380
Step-by-step explanation:
Pick any two points in table to find slope, let's use (4, 350) and (6, 330):
m = (y₂ - y₁) / (x₂ - x₁)
= (330 - 350) / (6 - 4)
= -20 / 2
m = -10
Pick any one point in table, let's use (4, 350) and slope m from above to find y-intercept:
y = mx + b
350 = -10(4) + b
350 = -40 + b
b = 390
Use m and b from above to form Equation of line:
y = mx + b
y = -10x + 390
Pick a few points from table to check equation y = -10x + 390 is valid:
Point (4, 350)
350 = -10(4) + 390
350 = -40 + 390
350 = 350
Point (8, 310)
310 = -10(8) + 390
310 = -80 + 390
310 = 310
What is y when x = 1:
y = -10x + 390
y = -10(1) + 390
y = -10 + 390
y = 380

his cheek, stiffened his gait; made his eyes red, his thin lips blue; and
spoke out shrewdly in his grating voice. A frosty rime' was on his head,
