Answer:
The equation of the parallel line would be y = -2/5x - 2
Step-by-step explanation:
In order to find this, we first need to find the slope of the first line. We can do this by solving for y.
2x + 5y = 10
5y = -2x + 10
y = -2/5x + 2
Now we know the slope to be -2/5 since parallel lines have the same slope. So we can use point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - -4 = -2/5(x - 5)
y + 4 = -2/5x + 2
y = -2/5x - 2
Answer:
The range in which at least 88.89% of the data will lie is (162,318).
Step-by-step explanation:
Given:
Average time spend online,
=
hrs =
mins
Standard deviation,
=
mins
We have to find the range in which at least 88.89% of the data will lie by using Chebyshev's theorem :
Formula :
Lower range =
Higher range = 
Now we have to find k values.
We know that the percentage of the data that lies within 'k' standard deviation is at least,1-1/k^2 and k > 1.
⇒ 
⇒
⇒
⇒ 
⇒
⇒ 
⇒ 
Plugging the value of k=3 in the formula above.
The range is
.
⇒
⇒
⇒ 
So,
The range in which at least 88.89% of the data will lie is (162,318).
Answer:
Step-by-step explanation:
<u>Solve the equation:</u>
- 12/x = 80/100
- 12/x = 4/5
- x = 12*5/4
- x = 15
Answer:
16.67%, 50%, 16.67%
Step-by-step explanation:
There are 6 different ways that the 4 kids can be paired up, so any one of the ways is rounded to 16.67%. So a and c are 16.67%
Not Zack is any pairing that doesn't have a Z. That is 3 out of 6, which is 50%.
Answer: The correct answer is 5/4
