Answer:
1. No 2. Yes 4: No The one above 4: Yes
Step-by-step explanation:
1. Although the line passes through the origin, it is curved, meaning that it cannot have a proportional relationship.
2. The line passes through the origin, and it is a straight line.
4. The line is straight, but it does not pass through the origin, or (0,0).
The one above 4: Straight line through the origin

Answer:
And rounded up we have that n=8068
Step-by-step explanation:
The margin of error for the proportion interval is given by this:
(a)
We want for this case a 95% of confidence desired, our significance level would be given by 
and 
. And the critical value would be given by:
The margin of error for this case is 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is 
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=8068
Answer:
A) 80
Step-by-step explanation:
b/4-23=-3
b/4=-3+23
b/4=20
b=20*4
b=80
As a decimal 4/15 = 0.2666667
As a decimal 3/10 = 0.3 [talk about close]
3/10 is bigger.
You could take an average to find something between 4/15 and 3/10
1/2(4/15 + 2/10)
1/2(8/30 + 6/30)
1/2(14/30)
1/2(7/15)
7/30 is between the two given numbers..
If the polygon or the figures are similar then it is
known that the ratios of their corresponding sides and angles are proportional.
In this item we can derive an equation that is,
<span>
AC/AE = AD/AB</span>
Substituting the known values,
<span>
4/7 = 10/AB</span>
<span>AB from the equation is equal to 70/4 or equal to 17 ½. </span>
