Answer:

The two ratios are equivalent.

Step-by-step explanation:

Reduce both fractions:

6/21 = 2/7  [Take out 3 from both sides]

8/28 = 2/7  [Take out 4 from both sides]

2/7 = 2/7

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 m
Grace [21]

Answer:

0.35

Step-by-step explanation:

we know that

The formula to use for uniform distribution is equal to

P( X < x) = \frac{x-a}{b-a}

where,

b is the upper limit of the distribution which is 5 minutes in this case.

a is the lower limit of the distribution which is 0 minutes in this case.

x is the concerned value which is 1.75 minutes in this case.

substitute the given values

P( X< 1.75) = \frac{1.75-0}{5-0}=0.35

That means

The probability that a randomly selected passenger has a waiting time less than 1.75 minutes is 0.35

An office room is 12 ft by 10 ft with a door that is 30 inches wide. How many feet of baseboard are needed to go around the room
Lina20 [59]
Draw a diagram to illustrate the problem as shown below.
The length of baseboard needed is AB + BC + CD + DE + FE.
Note that 30 in = 30/12 ft = 2.5 ft.

Because of the door opening,
AB + EF = 12 - 2.5 = 9.5 ft
Also,
BC = DE = 10 ft
CD = 12 ft.

The amount of baseboard needed is
AB + BC + CD + DE + FE
= (AB + EF) + BC + CD + DE
= 9.5 + 10 + 12 + 10
= 41.5 ft

Answer:
41.5 feet of baseboard.
