Answer:
B.52,551
Step-by-step explanation:
Use a z-table to find the corresponding z-score.
P(z>Z) = 0.95
P(z<Z) = 0.05
z = -1.645
Now find the corresponding income:
z = (x − μ) / σ
-1.645 = (x − 69000) / 10000
x = 52550
Answer:

Step-by-step explanation:
So to get a ratio of plates to bowl, you divide both the numbers by a common multiple, which I found the greatest to be 4. So you divide 52 by 4 and 24 by for to get a ratio of 13 plates to 6 bowls. (Also written as: 13:6, 13/6, or 13 to 6)

Complete question :
There are 575 fireworks to be shot off in a firework display every minute 12 new fireworks are shot off display write a verbal model and algebraic expression to represent the number of fireworks left to be shot off after t minutes.
Answer:
575 - 12t
Step-by-step explanation:
Given the following :
Total number of fireworks = 575
Number of shots per minute = 12
To calculate the number of fireworks left to be shot off after t minutes, The total number of fireworks already shot after the same time interval t in minutes, is first obtained, this is equivalent to (12*t). The result is then subtracted from the total number of fireworks to be shof off.
In algebraic terms
[total number of fireworks on display - (number of shots per minute × t)]
575 - 12t
