A.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is <span>symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.
b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed. </span>
Answer:
492.52
Step-by-step explanation:
The formula is P(t) = P(0) x (1+r/n)^nt so...
P(t) = 440 (1+0.058/1)^8
P(t) = 492.52
Answer:
-2x+25 D
Step-by-step explanation:
To determine how far it will go in an unspecified number of hours, we can let t = time in hours. The letter t will be our variable. Assuming that the car travels at the same speed, we can state that the rate is 55, and that will be our constant. The expression would then be:
Distance of car traveled in t hours, which we can denote as D(t) = 55 x t = 55t
This means that D is a function of t, and D represents the total distance traveled in t hours.
Answer:
<em>V(t) = π(4cos πt -5sinπt) cm</em>
Step-by-step explanation:
Given the displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 4 sin πt + 5 cos πt, where t is measured in seconds, the average velocity of the body will be expressed as the change in displacement of thee particle with respect to time.
This is expressed mathematically as V = ds/dt
Differentiate the displacement function to get the velocity V
V = 4πcos πt + (-5πsin πt)
open the parenthesis
V = 4πcos πt - 5πsin πt
bring out the common factor
V = π(4cos πt -5sinπt)
<em>Hence the average velocity of the body during each time is expressed as </em>
<em>V(t) = π(4cos πt -5sinπt) cm</em>
<em></em>
