Answer:

$\tan(24) = \frac{x}{13} \\ 0.445228685308 \times 13 = x \\ x = 5.787972909010 \\ x = 5.788$

$\tan(68) = \frac{27}{x} \\2.475086853416 \times x = 27 \\ x = 27 \div 2.475086853416 \\ x = 10.90870809754 \\ x = 10.909$

$\tan(0) = \frac{5}{12 } \\ \tan(0) = 0.41666663066666 \\ 0 = {76}^{0} 30$

A basketball player makes 70% of his free throws the random numbers below represent 20 trials for a simulation let the numbers 0

Nesterboy [21]

Answer:

40%

Step-by-step explanation:

Given the result of the simulation below:

(5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4)

(6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)

n(S)=20

The numbers 0 to 6 represent a made free throw .
The numbers 7 to 9 represent a missed free throw.
Therefore, any result containing 7 to 9 does not satisfy our requirement that the player makes both throws.

Let Event A be the event that the player made both throws

The pairs in which the player made both throws are:

(5,5) (0,6) (0,4) (1,4) (5,3) (3,5) (2,1) (0,6)

n(A)=8

Therefore:

$P(A)=\frac{n(A)}{n(S)}=\frac{8}{20}=0.4\\$

The probability that the player made both throws is 40%.

5 1/2 + 3 4/5 + 1 1/4 =

ratelena [41]

Answer:

$10\frac{11}{20}$

Step-by-step explanation:

$5\frac{1}{2} + 3\frac{4}{5} + 1\frac{1}{4}$

1.Find the LCM(Least Common Multiple).

That would be 20.

2.Multiply so all denominators are equal.

$5\frac{10}{20} + 3\frac{16}{20} + 1\frac{5}{20}$

3. Add

$9\frac{31}{20}$

4. Simplify

$10\frac{11}{20}$

What is the midpoint between 3.99 and 4

asambeis [7]

Answer:

3.995

Step-by-step explanation:

A midpoint is defined as a point that is exactly in the middle between two other points. The midpoint between two numbers is the number exactly in the middle of the two numbers. Calculating the midpoint is the same thing as calculating the average of two numbers. Therefore, you can calculate the midpoint between any two numbers by adding them together and dividing by two.
