Answer:

Option B - P(A)\cdot P(B)                          

Step-by-step explanation:

Given : The probability for success of an event is P(A), and the probability of success of a second event is P(B).

To find : What is the  probability of both events occurring, in that order?        

Solution :

The probability for success of an event is P(A).

The probability of success of a second event is P(B).    

As the events are independent so the probability of both events occurring, in that order is P(A)\cdot P(B)

Therefore, Option C is correct.

The probability of both events occurring, in that order is P(A)\cdot P(B)

There are 7 1/2 bottles of lemonade. Each bottle holds 1 5/6 quarts. How many quarts of lemonade are there?
erik [133]

Answer: There are 13³/₄ quarts of lemonade.

In decimal form, that is 13.75 quarts.

Step-by-step explanation:

Multiply 7 1/2 times 1 5/6

It may be good to change the mixed numbers to improper fractions:

7¹/₂ becomes 15/2  and 1⁵/₆ becomes 11/6

15/2 × 11/6 = 165/12

Changing that back to a mixed number involves dividing

165÷12 = 13 with a remainder of 9.

Make a fraction of the remainder as the numerator and 12 as the denominator. 9/12.

Then simplify: 9/12 = 3/4

Assemble the mixed number: 13³/₄

<em>Another way is to change the fractions to decimals and calculate:</em>

<em>7.5 × 1.833 = 13.7475.  Round to 13.75 and change back to a fraction if required.</em>

HELP! Please show full solutions. Will mark brainliest for THE BEST ANSWER. THANK YOU.
natali 33 [55]

Answer:

See Below

Step-by-step explanation:

A)

There are two runners that run at different average speeds, let these be Ra (runner a) and Rb (runner b). We also have two differnt distances that can be ran, let Leg A La and Leg b Lb. We get the equation bellow:

Total time = L_a/R_1 + L_b/R_2

B)

Mickey = 35km/h

Minnie = 25km/h

Leg A = 30

Leg B = 20

Since Mickey is the fastes, he should run the section with the longest distance:

Total time = L_a/R_1 + L_b/R_2\\Total time = 30_k_m/35_k_m_/_h + 20_k_m/25_k_m_/_h\\Total time = (30/35)_h + (28/35)_h\\Total time = (58/35)_h
