Answer:
2/3
Step-by-step explanation:
To find the reciprocal you first have to turn the mixed number into an improper fraction. (multiply denominator by whole number, then add the numerator, the denominator stays the same)
(1 x 2 )+ 1=3>>numerator | denominator stays the same>>2 | 3/2
Since the reciprocal is the number that you multiply by to get one, you can flip the numerator and denominator to get your reciprocal.
3/2>>2/3 ( the denominator came to the numerator, and the numerator came to the denominator)
2/3 is your reciprocal
To check your work, you can multiply the reciprocal and the regular number, if your answer is 1, then your reciprocal is correct. If your answer is anything else other than one, you may want to rethink your work.
correct reciprocal: 2/5 x 5/2 = 1
incorrect reciprocal: 2/5 x 6/2 = 5/6
So first you will have to go 10 units down which is showing the y-axis, so 1-10 will give us -9. Now that we have done this you reflect it over the y-axis which would give us (-11,-9)
Answer:
110
Step-by-step explanation:
110/5 = 22
22 - 11 = 11
Answer:
152
Step-by-step explanation:
Given the function :
C(x)=−15x+2304
The least Number of items, x that can be produced so that average cost does not exceed $33
C(x) = less than or equal to 33
33 = - 15x + 2304
33 - 2304 = - 15x
-2271 = - 15x
x = 2271 / 15
x = 151. 4
Hence, the least number of items that can be produced is 152
Answer:
0.82%
Step-by-step explanation:
First find the z-score.
z = (x − μ) / σ
z = (72 − 60) / 5
z = 2.4
Use a chart or calculator to find the probability.
P(Z > 2.4) = 1 − P(Z < 2.4)
P(Z > 2.4) = 1 − 0.9918
P(Z > 2.4) = 0.0082
