Answer:
14 tests in 7 weeks
Step-by-step explanation:
Answer:
C. 5 weeks.
Step-by-step explanation:
In this question we have a random variable that is equal to the sum of two normal-distributed random variables.
If we have two random variables X and Y, both normally distributed, the sum will have this properties:
To calculate the expected weeks that the donation exceeds $120, first we can calculate the probability of S>120:
The expected weeks can be calculated as the product of the number of weeks in the year (52) and this probability:
The nearest answer is C. 5 weeks.
<span>Current
employee = 40 340
A year ago a company has 40 340 – 24% employee.
Simply subtract 24% of 40 340 from 40 340 to get the number of employees last
year
=> 24% = .24
=> 40 340 x 0.24
=> 9681.6
Now, let’s subtract this 24% from the total number of employees in the current
=> 40 340 – 9 681.6 or 9682
=> 30 658.4 or 30 658
The number of employee last year before it increased 24%</span>
Answer:
-4
Step-by-step explanation:
-2 multiplied by 2 or doubled is -4
You need to find the vertex of the function.
The easiest way to do this is to graph it on a calculator like desmos.
but you can find the line of symmetry with this equation. x=-b/2a
x=-112/2(-16)
x= 3.5
Then plug that into the equation.
-16(3.5)^2+112(3.5)+30
226
226ft is the maximum height.
