Step-by-step explanation:
66. Δy = -3.4 Δx
Δy/Δx = -3.4
The slope of the line is -3.4. Slope-intercept equation of the line is:
y = -3.4x + b
Plug in the given point to find b:
2 = -3.4(4) + b
b = 15.6
Therefore, the equation is y = -3.4x + 15.6.
Use the equation to find the y coordinates.

68. Repeat the same steps as 66.
Δy = -1.7 Δx
Δy/Δx = -1.7
The slope of the line is -1.7. Slope-intercept equation of the line is:
y = -1.7x + b
Plug in the given point to find b:
3 = -1.7(-7) + b
b = -8.9
Therefore, the equation is y = -1.7x − 8.9.
Use the equation to find the x or y coordinates.

Step-by-step explanation:
you will need to round it down to 1,sorry if wrong this is my theory
Answer:
W<6
Step-by-step explanation:
3 times W
So 3W is less than < 18
Do 18 / 3 =6
Answer:
0.9056
Step-by-step explanation:
We are given;
Number of students enrolled in both General Chemistry and Calculus I = 540 students
Number of students who received an A in general chemistry = 51 students
Number of students who received an A in calculus = 59 students
Number of students who received an A in both general chemistry and calculus = 30 students
Now, we want to find the probability that a randomly chosen student did not receive an A in general chemistry.
So, first of all let's calculate number of students who didn't receive an A in chemistry.
So,
No without A in chemistry = 540 - 51 = 489 students
So, probability that a randomly chosen student did not receive an A in general chemistry = 489/540 = 0.9056
Answer:
177.87
Explanation:
<u>162.75 * 100</u> = 177.87
91.5
177.87 * 0.915 = 162.75
