\frac{8}{15} *\frac{25}{64}

we can multiply numerator with numerator and denominator with denominator

\frac{8*25}{15*64}

now, we can simplify it

\frac{1*25}{15*8}

\frac{1*5}{3*8}

so, we get

\frac{5}{24}..............Answer

Multiply fractions:

8*25= 200

15*64= 960

200/960, reduce; both can be cancelled by the common factor 40.

The answer is 5/24.

I hope this helps :)

In the triangle below, find the measurements of the unknown angles.
LUCKY_DIMON [66]

Answer:

E. 35°, 70°

Step-by-step explanation:

Sum of angles add up to 180° in every triangle.

Step 1: Set up equation

a + 2a + 75 = 180

Step 2: Combine like terms

3a + 75 = 180

Step 3: Subtract 75 on both sides

3a = 105

Step 4: Divide both sides by 3

a = 35

So 1 angle is 35°

Step 5: Plug in <em>a</em> to find last angle

2(35) = 70°

Find the probability that 3 randomly selected people all have the same birthday. ignore leap years. round to eight decimal place
IgorLugansk [536]

Answer:

Probability that 3 randomly selected persons have same birthday = 0.00820417

Step-by-step explanation:

Probability that 1 person has different birthday = 1

\text{Probability that 2nd person has different birthday than 1st = }\frac{364}{365}\\\\\text{Probability that the 3rd person has different from 1st and 2nd = }\frac{363}{365}

\text{Probability that the all three persons have different birthday = }1\times \frac{364}{365}\times \frac{363}{365}\\\\=0.99179583

The probability that all three persons have same birthday = 1 - 0.99179583

                                                                                                 = 0.00820417

Hence, probability that 3 randomly selected persons have same birthday = 0.00820417
