Evan randomly selects 30 marbles from a bag. His data is given in the table.

1 answer:

3 0

The probability of selecting a yellow marble is #of yellow marbles/total # of marbles= 6/30 or .2 or 20%

If there are 300 marbles in the bag, a good estimate for the total number of red marbles in the bag is 90.

9/30=.3 = the percentage of red marbles
.3(300) = 90

One taxi leaves at a stop at every 6 minutes a second taxi leaves the stop every 9 minutes if they leave at 4.00 p.m at what tim

qaws [65]

Both taxis will leave together at 04:18 PM after 04:00 PM

Step-by-step explanation:

We have to use the LCM to find the time on which both will leave at the same time,

Given

Departure interval for first taxi = 6 minutes

Departure interval for second taxi = 9 minutes

We have to find the LCM of 9 and 6

So,

Factors of 6: 6,12,<u>18</u>,24,30,36,42,48,54,60

Factors of 9: 9,<u>18</u>,27,36,45,54,63,72

The LCM is 18.

So,

Both taxis will leave together at 04:18 PM after 04:00 PM
