Answer:
2.28%
Step-by-step explanation:
Given that:
µ = 40 minutes ; σ = 3.5.
x = > 47 minutes
Obtain the standardized score, Z
Zscore = (x - μ) / σ
P(x > 47) = (47 - 40) / 3.5
P(x > 47) = 7 / 3.5
P(x > 47) = 2
P(z > 2) = 0.02275
Hence, Probability that next pizza delivery takes over 47 minutes is 0.02275 = 2.275% = 2.28%
Answer:
x < -4
Step-by-step explanation:
Hello!
I don't see the drop-down menus, but I will try to help as best as I can...
Like any other equation, you are trying to get x by itself.
Our first step will be to subtract 13 from both sides.
-7x + 13 > 41
-7x > 28
Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.
-7x/-7 > 28/-7
Doing the above equation will provide us with x all alone on one side:
x < -4
Hope I helped!

Answer:
C. 4.5
Step-by-step explanation:
Represent Macon to Albany on map with x
On map --- Real life
¼ inch ---- 5 miles
x inches ---- 90 miles
90 × ¼ = 5x
22.5 = 5x
22.5/5 = x
4.5 = x
