Answer:
2 : 3
Step-by-step explanation:
<em>Hello fellow human!</em>
red : blue - 8 : 12
The ratio is divisible by 4 - (8/4) = 2 ; (12/4) = 3
Hence, 2 : 3
The general formula for the margin of error would be:
z * √[p (1-p) ÷ n]
where:
z = values for selected confidence level
p = sample proportion
n = sample size
Since the confidence level is not given, we can only solve for the
<span>√[p (1-p) ÷ n] part.

p = 44/70
n = 70
√[44/70 (1 - (44/70) ÷ 70]
√[0.6286 (0.3714)] ÷ 70
√0.2335 ÷ 70
√0.0033357 = 0.05775 or 0.058 Choice B.
The equivalent expressions of 22c + 33d are (a), (c) and (e)
<h3>How to determine the equivalent expressions?</h3>
The expression is given as:
22c + 33d
Factor out 11 from the expression
11(2c + 3d)
Multiply by 1
1 * 11(2c + 3d)
Express 1 as -1 * -1
-1 * -1 * 11(2c + 3d)
Evaluate the product
(-11) * (-2c - 3d)
Also, we have:
22c + 33d
Multiply by 1
(22c + 33d) * 1
Express 1 as 3/3
(22c + 33d) * 3/3
Evaluate the product
(66c + 99d) * 1/3
Hence, the equivalent expressions are (a), (c) and (e)

Answer:
$16 million (provided that it is in US dollar) is equivalent to 16 orca/killer whales (each costs $1 million)
Explanation:
I'm not sure what equivalent you're looking for, but $16 million is worth a lot of money. You can actually purchase 16 killer whales with that. An orca whale is the largest member of the dolphin family and most of them can be purchased from Russia.
You may also use the money for a sharing program, such as the 16-million-dollar bike sharing program in Los Angeles. It would be a great advancement in the people's mobility. This will give more liberty to public spaces.
