Step-by-step explanation:

A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?

Answers

Answer:

y=1/6x-6

Step-by-step explanation:

The first step is to set up the equation. Since the lines are parallel the slopes will be the same.

Note: y=mx+b; m is the slope and b is the y-intercept

Since we know that the slopes are the same all we have to do is plug in (12,0) in the equation to find b (y-intercept),

0=1/6(12)+b

0=6+b

-6=b

Now that we know b all we have to do is put it in the formula y=mx+b

y=1/6x-6.

Answer:

y = (1/6)x - 2

Step-by-step explanation:

"Parallel" means "has the same slope as..."  so the slope of the line you want is 1/6.

y = (1/6)x + b     where b is the y-intercept (now, find it using the point (12, 0) ).

0 = (1/6)(12) + b

0 = 2 + b

b = -2

The equation is y = (1/6)x - 2

The width of the class interval in the given data is 4.

What is the range?

Range is the difference between the highest and lowest values of a set of observations

Range =Upper-class boundary of the highest interval – Lower class boundary of the lowest interval

79 - 45 = 34

What is the class width?

The class width is the difference between the upper bound and lower bound.

Class width : 49 - 45 = 4

3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.

17.2%
16.4%
15.7%
17.5%

Answers

Answer:

15.7%

Step-by-step explanation:

Experimental probability is the probability of something that is determined by doing an experiment.

To find the probability, divide the number of rolling a one and add all the occurrences of every other result.

So,

42 / (42 + 44 + 45 + 44 + 47 + 46) =

42 / 268 =

0.156716 =

15.6716

Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.
