Answer:
(value - mean)/standard deviation.
Now substitute 78 for the value, 84.5 for the mean, and 3.1 for the standard deviation.
Step-by-step explanation:
Answer:
The correct answer is;
A. 0.17
Step-by-step explanation:
Here are the provided details;
The average time taken for a cashier to handle an order, μ = 276 seconds
The deviation from the average, σ = 38 seconds
The z-score for an order processing time of x = 240 seconds can be calculated as follows;

Thus;

The resulting probability
P(z = -0.9474) = 0.17361
Hence, the estimated proportion of orders processed in under 240 seconds is roughly 0.17361 or 0.17 when rounded to two decimal places.
Answer:
The sales figure for the third year is
.
Step-by-step explanation:
Since sales data for the second year is unavailable, we denote it as x million.
Year 3's total sales amount to 32 million.
Calculate the sales account for year 3 as follows:

Answer:
B. (3, 0)
Step-by-step explanation:
The x-intercept signifies the location on the graph where it intersects the x-axis.
At the x-intercept, y=0 or f(x)=0.
Therefore, you need to examine the table for the instance where f(x)=0.
The value f(x)=0 is found at x=3 in the table.
We express this as an ordered pair.
Hence, the x-intercept is (3,0).
The right option is B.
Response:
The height of the water when it reaches 4 inches is
.
Detailed Explanation:
Flow rate of water from the cone = R=
Height of the cup = h = 6 inches
Radius of the cup = r = 3 inches

r = h/2
Volume of the cone = 






h = 4 inches



The height of the water when it is 4 inches deep is
.
