Answer
C) 325.41
Step by step explanation
The land-line telephone costs =$25.95
Utilities tax percentage = 4.5% = 4.5/100 = 0.045
Utility tax for amount $25.95 = 25.95*0.045
Utility tax = $1.17
The amount of telephone bill with tax = $25.95 + $1.17
= $27.12
There are 12 months in a year.
Telephone bill for a year = $27.12 * 12
= $325.44
Therefore, the nearest amount $325.41
You need to pay $325.41 as telephone bill for a year.
Thank you.
Answer: There are 48 total plants.
Step-by-step explanation:
x = y/p%
37.5/100 = 0.375
18/0.375 = 48
35,000 ft - 6,000 ft = 29,000 ft
This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
Answer:
A. Z = 2 + N13
Step-by-step explanation:
Let's solve your equation step-by-step.
0=z2+4z−9
Step 1: Subtract z^2+4z-9 from both sides.
0−(z2+4z−9)=z2+4z−9−(z2+4z−9)
−z2−4z+9=0
For this equation: a=-1, b=-4, c=9
−1z2+−4z+9=0
Step 2: Use quadratic formula with a=-1, b=-4, c=9.
z=
−b±√b2−4ac
2a
z=
−(−4)±√(−4)2−4(−1)(9)
2(−1)
z=
4±√52
−2
z=−2−√13 or z=−2+√13
