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.

Describe how to find the mean, median and mode of a set of data. what does each mean
Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]

A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

Answer:
Step-by-step explanation:
m∠2=71° because they are vertical angles so are congruent
those 4 angles in the midle will add up to 360°
∠3+∠5=360-2*71=218 so
m∠3=218/2=109°
m∠5=109°
mostly use that the sum of angles in a Δ add to 180
m∠1=180-47-71=62°
m∠4=180-109-36=35°
m∠6=180-42-109=29°
use that opposide ∠s in a quadrinateral add to 180
m∠7=180-47-35-29= °69
m∠8=180-42-62-36= °40

If 4 gal of pure ethanol are added to 46 gal of 2% ethanol how much of the final solution do you have? How much ethanol is contained in the mixture? What is the strength (percentage) of ethanol in the mixture?
Answer:
100 i belive
Step-by-step explanation:
you add 4+46=50x2=100
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is 4 gal of pure ethanol is added to 46 gal of 2% ethanol.
In 46 gal of 2% ethanol, we have (46 x 0.02) = 0.92 gallons of pure ethanol.
When 4 gal of pure ethanol is added, total ethanol in the mixture = 4 + 0.92 = 4.92 gallons
Total mixture quantity in gallons = 46 + 4 = 50 gallons
The percentage of the ethanol in the mixture will be -
(4.92/50) x 100 = 9.84%
Therefore, the percentage of the ethanol in the mixture will be 9.84%.
