On a number line, -5 is to the left of 0.
Remember, on a number line, positive numbers (including fractions, decimals and surds) are to the right of 0:
----------------------------------------------------------------------->
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Negative numbers (including rational and irrational numbers) are to the left of 0:
<-----------------------------------------------------------------
-8 -7 -6 -5 -4 -3 -2 -1 0

Answer:
B. Slightly more than $5
Step-by-step explanation:
y = 2x + 3
Firstly we check variables to make sure we understand.
y = dollars
x = pounds
On the scale, it says 1.126 lb. Which means 1.126 pounds.
And so, x = 1.126
y = 2x + 3
y = 2(1.126) + 3
y = 2.252 + 3
y = 2.252
The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.
Answer:
(A) The minimum sample size required achieve the margin of error of 0.04 is 601.
(B) The minimum sample size required achieve a margin of error of 0.02 is 2401.
Step-by-step explanation:
Let us assume that the percentage of support for the candidate, among voters in her district, is 50%.
(A)
The margin of error, <em>MOE</em> = 0.04.
The formula for margin of error is:
The critical value of <em>z</em> for 95% confidence interval is:
Compute the minimum sample size required as follows:
Thus, the minimum sample size required achieve the margin of error of 0.04 is 601.
(B)
The margin of error, <em>MOE</em> = 0.02.
The formula for margin of error is:
The critical value of <em>z</em> for 95% confidence interval is:
Compute the minimum sample size required as follows:
Thus, the minimum sample size required achieve a margin of error of 0.02 is 2401.
