Answer:add 8 red
Step-by-step explanation:
the ratio is 1 red to 3 blue so you would add 8 red so it would be 9-3 which when u simplify it would be 3:1
Answer:
184
Step-by-step explanation:
in the number 128 the number eight is right it should be to the right then in the number157 one is right it should be to the left in 841 8and 1 are in the wrong position 8 - right 1 - left then in the number 624 the number 4 is right but in the wrong position it should be in the middle the answer is digit 1,8,4
Solutions
We know that <span>Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18.
</span>
Maddy spends 2 dollars more.
Therefore the correct answer is the last option.

The domain is the x-values used by the graph, so you want to see how your graph lines up with respect to the x-axis.
This graph starts out with an x-value of 2 (although it doesn't really use 2, since it's an open circle) and then continues to the right forever.
The domain is x > –2.
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%
