The correct answer is B, C and E
Answer:
![x=50](https://tex.z-dn.net/?f=x%3D50)
Step-by-step explanation:
we know that
If LM is the midsegment
then
![LM=\frac{1}{2}(AB+DC)](https://tex.z-dn.net/?f=LM%3D%5Cfrac%7B1%7D%7B2%7D%28AB%2BDC%29)
substitute the given values
![4x+3=\frac{1}{2}(x+8+348)](https://tex.z-dn.net/?f=4x%2B3%3D%5Cfrac%7B1%7D%7B2%7D%28x%2B8%2B348%29)
Solve for x
![8x+6=(x+356)](https://tex.z-dn.net/?f=8x%2B6%3D%28x%2B356%29)
![8x-x=356-6](https://tex.z-dn.net/?f=8x-x%3D356-6)
![7x=350](https://tex.z-dn.net/?f=7x%3D350)
![x=350/7](https://tex.z-dn.net/?f=x%3D350%2F7)

Answer:the probability that a pensioner catches a flu is 0.3 or ![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
Step-by-step explanation:
<u>Data:</u>
a) Pensioners who have had a flu jab = ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
b) Pensioners who did not had a flu jab = 1 -
= ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
For the first pair of arrows: a is the probability of the upper arrow and b is the probability of the lower arrow.
<em>If pensioner have had a flu jab, the probability of catching flu is
</em>
Data:
c) Catching flu = ![\frac{1}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B30%7D)
d) Not catching flu = 1 -
= ![\frac{29}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B30%7D)
The second pair of arrows on the top: Top arrow is c and bottom arrow is d
<em>If pensioner did not have a flu jab, the probability of catching flu is
</em>
<u>Data:</u>
e) Catching flu = ![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D)
f) Not catching flu = 1 -
= ![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
The second pair of arrows on the bottom: Top arrow is e and bottom arrow is f.
Q) Probability pensioner catches a flu
P(catches the flu given that he had the flu jab) + P(catches the flu given that he did not have the flu jab)
(
x
) + (
x
)
= 0.02 + 0.28
= 0.3
Therefore, the probability that a pensioner catches a flu is 0.3 or ![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
