Jacob surveyed members of three different gyms and recorded the number of hours they exercised last week. The mean and standard deviation (SD), of the data he gathered, is shown in the table.
Gym A, Mean = 7. SD = 2.9
Gym b, Mean = 8, SD = 4.2
Gym c, Mean = 6, SD = 3.2
Use the information to complete the following statement.
The members of gym [A, B, or C] show the most consistency in the number of hours they exercised last week because the [mean, standard deviation] of this data set is the [lowest or highest]. inside brackets are the options
Answer:
A, Standard Deviation, Lowest
Step-by-step explanation:
I got it right lol
The members of gym A show the most consistency in the number of hours they exercised last week because the standard deviation of this data set is the lowest.
What is mean?"The mean is one of the measures of central tendency. Mean is nothing but the average of the given set of values."
What is standard deviation?"The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range."
Given, Gym A has the lowest value of SD = 2.9, Gym C has the second lowest vale of SD = 3.2 and Gym B has the highest value of SD = 4.2.
We know, standard deviation is measured with the help of the differences of a group of data and the mean.
Therefore, more the standard deviation is less, the data will be more consistent.
Therefore, Gym A has shown the more consistency in terms of number of hours exercised last week.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (-5,5) and -9,-9
Answer:
y= 3.5x+22.5
Step-by-step explanation:
The standard equation of a line a expressed as y = MX+c
m is the slope
c is the y-intecept
Get the slope
m = y2-y1/x2-x1
m = -9-5/-9+5
m = -14/-4
m = 7/2
Get the y- intercept
Substitute any of the point say (-5,5) and m = 7/2 into the equation y = MX+c
5 = 7/2(-5)+c
5= -35/2+c
5 =-17.5+c
c = 5+17.5
c =22.5
Get the required equation
Recall that y = MX+c
y= 3.5x+22.5

Sine and Cosine both function will Increase in [tex](3\pi /2 , 2\pi )[/tex]
What is Sine and Cosine function ?Sine, Cosine are the main functions used in Trigonometry and are based on a Right-Angled Triangle.
from 0 to 2π, sin (x) is increasing on the intervals (0, π/2) and (3π/2 , 2π), and decreasing on the interval (π/2 , 3π/2).from 0 to 2π, cos (x) is decreasing on (0 , π) increasing on (π , 2π).So common interval in which both sine and cosine functions are increasing is [tex](3\pi /2 , 2\pi )[/tex]

15-18=-3
Answer:
-3
Step-by-step explanation:
Given equation for reference: 3x + (2 - 4x)
3(5) + (2 - 4(5)) is with x substituted for 5.
Next, we just follow PEMDAS like any other expression
First off, parentheses.
2 - 4(5), starting with multiplication, and then subtraction
The result of the parentheses is -18
3(5) - 18 is the result when we put that back into the expression.
Next, we multiply 3 by 5; the result being
15 - 18
Now, we just subtract 18 from fifteen, getting -3

Step-by-step explanation:
A rectangle has a perimeter of 240 inches. The width is 23 inches less than the length. Find the length and width (perimeter of rectangle =2l+2w)
The length and width of the given rectangle are 71.5 inches and 48.5 inches respectively.
Given that, a rectangle has a perimeter of 240 inches.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Let the length of a rectangle be l.
The width is 23 inches less than the length.
Then, the width of a rectangle will be l-23
So, perimeter = 2(l+l-23)
⇒ 2(2l-23) = 240
⇒ 4l-46=240
⇒ 4l=240+46
⇒ 4l=286
⇒ l=286/4
⇒ l=71.5 inches
So, width = l-23
=71.5-23 = 48.5 inches
Therefore, the length and width of the given rectangle are 71.5 inches and 48.5 inches respectively.
