X=9 how to solve: 72+48=8x+48
72=8x 8*9=72
Answer:
The slope is undefined and the equation of the line is x = 9 ⇒ C
Step-by-step explanation:
- Parallel lines have the same slopes and different y-intercepts
- The slope of any vertical line is undefined
- The equation of any vertical line is x = a, where a is the x-coordinate of a point that lies on the line
- All x-coordinates of the points lie on a vertical line equal
Let us solve the question
∵ The line is parallel to the y-axis
∵ The y-axis is a vertical line
→ By using the second note above
∴ The slope of the y-axis is undefined
→ By using the first note above
∴ The slope of the line is undefined
→ By using the third note above
∵ The equation of the vertical line is x = a
∵ a is the x-coordinate of a point on the line
∵ The line passes through the point (9, -1)
∴ a = 9
∴ The equation of the line is x = 9
Answer:
The probability is 0.2356.
Step-by-step explanation:
Let X is the event of using the smartphone in meetings or classes,
Given,
The probability of using the smartphone in meetings or classes, p = 51 % = 0.51,
So, the probability of not using smartphone in meetings or classes, q = 1 - p = 1 - 0.51 = 0.49,
Thus, the probability that fewer than 5 of them use their smartphones in meetings or classes.
P(X<5) = P(X=0) + P(X=1) + P(X=2) + P(X=3)+P(X=4)
Since, binomial distribution formula is,
Where, 
Here, n = 11,
Hence, the probability that fewer than 5 of them use their smartphones in meetings or classes
