2 * 2 and 3/4.
2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4
2 * 11/4 = 22 / 4 = 5 and 2/4
= 5 and 2/4 or 5 and 1/2 or 5.5
Hope this helps.
Answer: The distance from Thomas to Sebastian is 58.39 feet
Step-by-step explanation: Please see the attachments below
We can solve this problem by referring to the standard
probability distribution tables for z.
We are required to find for the number of samples given the
proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value
of z equivalent to:
z = 1.96
Since the problem states that it should be within the true
proportion then p = 0.5
Now we can find for the sample size using the formula:
n = (z^2) p q /E^2
where,
<span> p = 0.5</span>
q = 1 – p = 0.5
E = estimate of 5% = 0.05
Substituting:
n = (1.96^2) 0.5 * 0.5 / 0.05^2
n = 384.16

<em><u>Answer</u></em>:
a+a+a = 3a.
4b-b = 3b.
3x²+x² = 4x².
<u><em>explanation</em></u>
a+a+a = 3a.
4b-b = b(4 - 1) = b × 3 = 3b.
3x²+x² = x²(3 + 1) = x² × 4 = 4x².
