Answer:
1/4
Step-by-step explanation:
8 divided by 2= 0.25=1/4
Answer:
First, put it into slope/intercept form so you can see what you've got.
"Slope/intercept form" is y = everything else .
So that means you have to take the equation you have and "solve it for 'y' ".
2y - 10x = 20
Add 10x to each side: 2y = 10x + 20
Divide each side by 2 : y = 5x + 10
And that's exactly the information you need to graph it. On your graph,
mark a little dot on the y-axis at 10, and draw a line through that dot
with a slope of 5.
Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Answer:
73% of readers who are satisfied with their lives would be described as a sample statistic.
Step-by-step explanation:
The right option is D.
A) The population include all the readers of USA today.
B) The sample includes all the readers that answer the poll, wether they answer Yes or No.
C) A population statistic would be the population proportion. It is not mentioned in the text, and it would have to be estimated from the result of the sample.
D) A sample statistic is the proportion of readers that answer affirmatively the poll (p=0.73).
