Answer:
39.29 ft
Step-by-step explanation:
We are made to know that the fountain contains two semi circles and a quarter-circle.
This means the fountain contains a total of 1+1/4 = 1.25 circles
Interestingly, the circles are similar and have the same diameter.
Now the perimeter of a circle with diameter 10ft is simply πd = 10 π
Now, since we have a total of 1.25 circles, the total perimeter would be 1.25 * 10 π = 12.5 π ft
With π as 22/7, the actual value of the perimeter would be 39.29 ft
Answer:
An invoice was paid an average of 20 days after it was received.
Mean =
Standard deviation =
Now we are supposed to find what percent of the invoices were paid within 15 days of receipt i.e.P(x<15)
Formula :
At x = 15
Substitute the values
Refer the z table for p value
So, p value = 0.1587
So, 15.87% of the invoices were paid within 15 days of receipt
Step-by-step explanation:
The number of cookies and trays are illustrations of greatest common factors.
- The number of trays is 8
- 6 chocolate chips, 8 rainbows and 15 oatmeal cookies would fit each tray
The given parameters are:
<u>(a) The number of trays</u>
To do this, we simply calculate the greatest common factor of 48, 64 and 120
Factorize the numbers, as follows:
So, the GCF is:
Hence, the number of tray is 8
<u>(b) The number of each type of cookie</u>
We have
Divide each cookie by the number of trays
So, we have:
Hence, 6 chocolate chips, 8 rainbows and 15 oatmeal cookies would fit each tray
