Answer:

The Probability is found as:

A) P = 23/36

Step-by-step explanation:

When two dices are rolled, each dice has a total outcomes of 6. The total number of outcomes of both dices is:

$6\cdot6=36\\$

Find the pair of values (x₁ , x₂) for which sum is 6 or odd number, where x₁ is the number on first dice and x₂ is the number on the second dice.

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

So Desired number outcomes = 23

So, Probability is given as:

P = Desired number outcomes / Total number of outcomes

P = 23/36

IRINA_888 [86]

Answer:

c) The required representation of the given situation is 4 m + 3 > 75

Step-by-step explanation:

Let us assume, the owner plans to have m tables.

Each table can seat 4 people.

⇒The number of people seated in m tables = m times 4 = 4 m

Also, the additional number of people seated ta chef's table = 3

So, Total seated people in the restaurant

= People seated at m tables + People seated at chef's table

= 4 m + 3

Now, the seating arrangement is for more than 75 people.

⇒ 4 m + 3 > 75

Hence, the required representation of the given situation is 4 m + 3 > 75

Help me pls and pls explain

Luda [366]

Answer:

5.1 mph

Step-by-step explanation:

she ran 3 2/5 miles in 2/3 hours.

that is the essential information to solve the problem. everything else is just there to give you "atmosphere" and Shao to confuse you.

the question is simply : what was her speed in mph ?

that means we need to bring the ratio of

3 2/5 miles / 2/3 hours

to 1 hour in the denominator (instead of 2/3 hours).

because we need that to express miles per (one) hour.

so, what do we need to multiply 2/3 with to get 1 (=3/3) ?

2/3 × x = 1

2x = 3

x = 3/2

so, to get 1 hour, we need to multiply the denominator by 3/2.

and to keep the original value of the ratio, we need to multiply also the numerator by the same 3/2.

speed = (3 2/5 miles × 3/2) / (2/3 hours × 3/2) =

= (17/5 miles × 3/2) / (1 hour) = 51/10 miles / 1 hour =

= 5.1 miles / 1 hour = 5.1 mph
