Answer:
0.02
Step-by-step explanation:
Given a normal distribution :
Mean income (m) = 25000
Standard deviation of income (s) = 6000
X ≥ 12000
Using the relation to fund the standardized score :
Zscore =(x - m) / s
Zscore = ( 12000 - 25000) / 6000
Zscore = -13000 / 6000
Zscore = - 2.167
Using a z probability calculator :
P(Z ≤ - 2.167) = 0.015117
= 0.02
I think it is point 3. Hope that helps
Answer:
6 phones and 18 accessories
Step-by-step explanation:
12P + 3.50A = 135
A = 12 + P
12P + 3.50(12 + P) = 135,
12P + 42 +3.50P = 135
15.50P = 93
P = 6 phones
A = 12 + 6 = 18 accessories
Answer:
8
Step-by-step explanation:
The interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds
<h3>How to interpret the expression?</h3>
The expression is given as:
-10c/60 seconds
From the question, we understand that:
The temperature decreases by 10c every minute
When converted to seconds, we have:
10c/60
Hence, the interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds
