If you would like to know how many hours will Lena need to work before she can afford to buy the computer, you can calculate this using the following steps:
$900 - $473 = $427
$427 / $7 = 61 hours of yard work
Result: Lena will need to work 61 hours before she can afford to buy the computer.
$945 because 135 divided by 5 is 27 and 27 times 135 equals 945
Answer:
0.02 or 2%
Step-by-step explanation:
Theoretical probability calculated by dividing the number of events you want to calculate(green marble) with the total event possible(red + blue + green). There are 4 red marbles, 5 blue marbles, and 1 green marble. The probability will be: 1/(4+5+1)= 1/10= 10%
The result of the experiment is:
Red=22
Blue= 24
Green=4
Experimental probability calculated by dividing the number of events occurs with the total number of trials. We pull green 4 times and do 50x pulls, so the probability is: 4/50= 8%
Difference between the theoretical probability and the experimental probability is: 10%- 8%= 2%
This problem needs more information. Probably a picture of a figure with several angles from which you can state the relationship between the angle 4 and the angle 8.
Then I have to assume this relation to show you how to work.
My assumptio will be that angle 4 and angle 8 are vertically opposite triangles.
That means that both triangles are congruent.
Then 3x = x + 40
=> 2x = 40
=> x = 20
Then agle 4 is 3x = 3*20 = 60 degrees.
Answer: 60 degrees, subject to the assumption considered.
