3 0

Answer:

D

Step-by-step explanation:

\sin(30)  =  \frac{n}{ \frac{10 \sqrt{3} }{3} }   \\ 0.5 =  \frac{n}{5.77} \\ n = 2.88 =  \frac{5 \sqrt{3} }{3}

\cos(30)  =  \frac{m}{ \frac{10 \sqrt{3} }{3} }  \\ 0.866 =  \frac{m}{5.77}  \\ m = 5

. Three out of four students in school have at least one sibling. If there are 300 students in your school, how many would have
tekilochka [14]

Answer: 225 students would have at least one sibling.

Step-by-step explanation:

Three out of four is the same as  3/4 meaning that if there are 300 students in your school then 3/4 times 300 will give the number of students with at least one sibling.  

3/4 * 300 = 225  

This means 225 students would have at least one sibling.

According to the graph, what is the experimental probability of selecting the letter E?
Daniel [21]

The experimental probability of letter E is: 3/25

Step-by-step explanation:

The given diagram is the number of outcomes for each letter is given

We have to find the total number of outcomes for finding the experimental probability of letter E

So,

Total outcomes = n(S) = 5+12+8+10+6+9 = 50

Number of outcomes for Letter E = n(E) = 6

So the experimental probability will be:

P(E) = \frac{n(E)}{n(S)}\\\\=\frac{6}{50}\\\\= \frac{3}{25}

Hence,

The experimental probability of letter E is: 3/25
