Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
Step-by-step explanation:
Given: Average monthly electric bill in Illinois = $83
Average monthly electric bill in Florida = $102
Formula of z :
In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.
In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.
Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
Answer:
Given:
Relation between position of an object at time t is given by:
s(t) = -9 - 3t
To Find:
Instantaneous velocity (v) at t = 8
Step-by-step explanation:
To find instantaneous velocity we will differentiate relation between position of an object at time t by t:
Differentiate the sum term by term and factor out constants:
The derivative of -9 is zero:
Simplify the expression:
The derivative of t is 1:
Simplify the expression:
(As, there is no variable after differentiating the relation between position of an object at time t by t so at time t = 8 is of no use.)
So,
Instantaneous velocity (v) at t = 8 is -3
Approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter
<em><u>Solution:</u></em>
Given semicircle with a radius of 30 centimeters
<em><u>To find: approximate circumference of a semicircle</u></em>
To find circumference of semicircle we can divide the circumference of circle by 2
circumference of semicircle = circumference of circle 2
Substituting the given radius = 30 cm,
Thus approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter
Answer:
166 2/3
Step-by-step explanation:
So the wuestion asked how many miles each day. Well because 500 cant evely go into 3 we have to simplify it. And when you simplify 500/3 we get 166 2/3.
