ANSWER CHOICE C
We have been given two box plots representing attendance at a local movie theater and high school basketball games. WE are asked to choose the correct option about the measure the spread of the data represented by box plots.
Since we know that Standard deviation is not a good measure of spread in highly skewed data. IQR is better measure of spread for highly skewed data.
We can see that box plot representing attendance at movies is right skewed, therefore, mean will be greater than median and SD will not be a good measure of spread.
Box plot representing basket-ball games attendance is left skewed left,therefore, mean will be less than median and SD will not be a good measure of spread.
Our both box plots are highly skewed, therefore, the IQR is the best measurement of spread for games and movies and option C is the correct choice.
Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)
Answer:
1.7
Step-by-step explanation:
1 + 7/10
= 1 + 0.7
= 1.7
Answer:
113
Step-by-step explanation:
The given shape has 6 angles so it's a hexagon and the sum of interior angles in a hexagon is = 720
To find the the value of x we need to add all given values up and subtract it from 720:
88 + 142 + 105 + 136 + 136 + x = 720
607 + x = 720 subtract 607 from both sides
x = 113
The equation for resolving couples will come in place
Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
<h3>
Couple moment and Cartesian vector</h3>
Couple moment:This looks at the product of the forces acting on a body( in this context a steering wheel ) by the perpendicular distance that exist amidst the forces.
Cartesian vector:this is the representation of unit vectors by i and j along the x-axis and the y-axis, respectively.
Therefore, in calculating the <em>couple</em> moment t acting on the steering wheel, the equation for resolving couples will come in place
Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
