Answer:
234 times
Step-by-step explanation:
<u>Number of times the number 7 appears in a hundred</u>
7 as units digit (07-17-27 ..... 97): 10 times
7 as tens digit (70-71-72..... 79): 10 times
20 times the digit 7 appears in first one hundred (0-100)
Let's calculate how many times 7 would be as units or tens in 7 hundreds
20X7 = 140 times digit 7 appears until number 699
<u>Now, from 700 to 777</u>
7 as hundreds digit (700-701-702 .... 777): 78 times
7 as tens digit (770-771-772 .... 777): 8 times
7 as units digit (707-717-727....777): 8 times
78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times
140 + 94 = 234 times
There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)
This means he has a 3/6 = 1/2 chance of doing that.
He has a 1/2 chance of getting tails on the coin.
The probability of doing both would be the probability of the cube roll x the probability of the coin toss:
1/2 x 1/2= 1/4
The answer is 1/4
Answer:
16.5
Step-by-step explanation:
V = l • w • h
Plug in the values:
90 = l • w • 6
Divide 6 on both sides:
15 = l • w
Break down 15 into factors:
5 • 3
Answer check:
5 • 3 • 6 = 90
The surface area of the shaded region is:
5 • 3 = 15
(I hope this is correct!)
