Answer:

Step-by-step explanation:

If you observe closely the graduated cylinder, you would find that the correct degree of precision is 33.5, because the mark is at that number.

Now, notice that the blue part has a curvy ending. The important matter there is that you should measure using the center of the instrument, that's why the answer is 33.5. Because we don't look the edges.

Fifteen people have been exposed to a particular disease. Each one independently has a 40% chance of contracting the disease. A

valina [46]

Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , $X\sim Binomial(n=15,p=0.40)$

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : $P(X=x)= ^nC_xp^x(1-p)^{n-x}$

Then , the probability that the hospital’s capacity will be exceeded

$P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]$

$=0.095$

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.
