Answer:
Pool A.
Step-by-step explanation:
This can be solved through ratios. You would write it as So, for the first one, and for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So, , and So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.
(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)
Answer:
The angle that the ramp forms with the ground is 27.5°
Step-by-step explanation:
Check the attachment for the figure.
Using the SOH CAH TOA trigonometry identity
For TOA
Tan(theta) = opposite/adjacent
Given opposite = 1.3m(side facing the angle of inclination
Adjacent = bottom of the ramp= 2.5m
Tan(theta) = 1.3/2.5
Tan(theta) = 0.52
theta = arctan0.52
theta = 27.5°
Answer:
0.9544 or 95.44%
Step-by-step explanation:
Given: Mean= 37
Standard deviation= 6
x= 25 and 49.
Now, solving to find the percentage of daily phone calls numbering between 25 and 49.
first calculating the z-score for daily 25 phone calls.
Formula;
z-score=
z-score=
∴ z-score for daily 25 phone call is -2.
Next, calculating the z-score for daily 49 phone calls.
z-score=
z-score=
∴ z-score for daily 49 phone call is 2.
We can observe that there is change in z-score for 25 phone call and 49 phone call.
Lets use the normal distribution table to find the percentage of daily phone calls numbering between 25 and 49.
⇒ Percentage of daily phone calls numbering between 25 and 49=
⇒ Percentage of daily phone calls numbering between 25 and 49=
Using normal distribution table
⇒ Percentage of daily phone calls numbering between 25 and 49=
Hence, 0.9544 or 95.44% is the percentage of daily phone calls numbering between 25 and 49.
