Answer:
75%
Step-by-step explanation:
Since it's saying less than 7, that tells you-you have 6 numbers less than 7. I put 6/8 which converts to 75%
Answer:
A bicycle store installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The owner of the store estimates the number of properly installed tires per week using the process below.
In the first hour of work on Monday, 49 out of 50 tires were properly installed.
So, there were about 8(49) = 392 properly installed tires on Monday.
Considering 5 working days per week, 5(392) = 1,960 is the number of tires properly installed in one week.
Which best explains the validity of the results?
The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.
The results are likely invalid because the entire population during one week was not part of the sample.
<u>The results are likely valid because a large number of tires produced during the week were part of the sample.
</u>
The results are likely valid because each tire sampled was part of the population of tires that week.

They ate the same amount of apple because 2 divided by 4 is .5, and so is 1 divided by 2. Have a nice night!
Answer:
<u><em>x = 3</em></u>
<u><em>angle B = 70 degree</em></u>
<u><em>angle C = 50 degree</em></u>
Step-by-step explanation:
<em>angle B + angle C = angle CDA ( exterior angle property)</em>
(22x+4) + (15x +5) = 120
22x + 15x + 4 + 5 = 120
37x + 9 = 120
37x = 120- 9
37x = 111
x = 
x = 3
angle B = 22x + 4
= 22(3) +4
= 66 +4
angle B = 70 degree
angle C = 15x+5
= 15( 3) + 5
= 45 + 5
angle C = 50 degree
