Hi there!
I will help you with joy!
Arabic numbers - 1, 2, ..., 10,..; Roman numerals: I, II, ... X, ..
Match the Arabic numerals to Roman numerals.
I = 1
V = 5
X= 10
L = 50
C=100
D=500
M = 1,000
Hope it helps!
Enjoy your day!
Ask me if you have any questions.

Answer:
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
Step-by-step explanation:
Given that in 2013, the Pew Research Foundation reported that "45% of U.S. adults report that they live with one or more chronic conditions", and the standard error for this estimate is 1.2%
Let us check one by one answers given
a) False. Because we can say 95% or 90% confident only that the true percent of US adults cannot be true.
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
c) False this does not give whether less than 50% or not unless we know the confidence interval range.
d) False, std error is a measure of variation of all the items from the mean.
Answer:
I cant help because its rly blurry but I think the answer is 120¿
Answer:
(2, 13)
Step-by-step explanation:
Since they both equal y, you can equal them to each other.
8x - 3 = 2x + 9
Subtract 2x from both sides.
6x - 3 = 9
Add 3 to both sides.
6x = 12
Now divide 6 on both sides.
x = 2
Now that we have found x, we need to find y. Just plug in x to the equations.
y = 2(2) + 9
y = 4 + 9
y = 13
Now, if the next equal has the same y, then both are true.
8(2) -3 = y
16-3=y
13 = y
So therefor, both x and y are true.
