Answer:
A
B
C
Step-by-step explanation:
Well the sides of the smaller squares have to be greater than the biggest when put together.
a + b > c
So we need to find the square root of 55.
≅ <u>7.4</u>
<u />
Now for option A)
srt ⇒ 12 ≅3.5
srt ⇒ 43 ≅ 6.6
3.5 + 6.6 = <u>10.1</u>
So option A is correct.
Option B)
srt ⇒ 14 ≅ 3.7
srt ⇒ 40 ≅ 6.3
3.7 + 6.3 = <u>10</u>
So option B is also correct.
Option C)
srt ⇒ 16 = 4
srt ⇒ 37 ≅ 6.1
4 + 6.1 = <u>10.1</u>
So option C is also correct.
<em>Therefore,</em>
<em>all options are correct.</em>

Answer:
Probability = 0.0228
Step-by-step explanation:
Let X be a random variable which is a measure of the time to get a passenger on board.
Mean(u) = 22.5mins
Standard deviation (s) = 5.25mins
X = 33mins
From Pr(X>33), starting from Pr(X = 33)
For normal distribution, Z = 7(X - u) /s
Z= (33 -22.5) /5.25
= 10.5/5.25
= 2
From the normal distribution table, 2 = 0.4772
Recall that
If Z is positive,
Pr(x>a) = 0.5 - table value
Pr(x<a) = 0.5 + table value
Therefore;
Pr(X>33) = 0.5 - 04772
= 0.0228
Yes is 12% good job hope this helps
