In a large population, 60 % of the people have been vaccinated. If 5 people are randomly selected, what is the probability that
Delvig [45]
<h3>Answer:    0.98976</h3>

===========================================================

Explanation:

60% of the people have been vaccinated, so 40% have not.

The probability of getting five people in a row that aren't vaccinated is (0.40)^5 = 0.01024

Subtract this from 1 to get the probability of at least one vaccinated person in the sample of five.

1-0.01024 = 0.98976

This works because the events "at least one vaccinated" and "none vaccinated" are complementary. One or the other must happen, which means the two probabilities add to 1.

Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes.
stepladder [879]

Answer:

12\frac{1}{8}\ yd

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})

Convert mixed number to an improper fraction

1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}

2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}

2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}

substitute

3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})

5+\frac{21}{8}+\frac{9}{2}

\frac{40+21+36}{8}=\frac{97}{8}\ yd

Convert to mixed number

\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd

F(x)= 2-1/x<br>g(x)= x/2<br><br>what is f(g(x))?
kompoz [17]
To find f(g(x)), plug g(x) into f(x) and simplify.

f(x/2) = 2 - 1/(x/2)

All you have to do is simplify the right side of the equation.

Take it from here.

Add using a number line 5/6+(-1 1/6) drag and drop word sum to the correct value on the number line
wel
<span>To find this answer, the second value needs to be converted into an improper fraction. (-1 1/6) becomes (-7/6) when properly converted. Then, 5/6 + (-7/6) becomes the same as (5/6) - (7/6). Since both have common denominators, the numerators can simply be subtracted: (5-7) = -2. This leaves a sum of (-2/6), which can be reduced to (-1/3).</span>
