Jodie is on the swim team. Below are four of her times swimming 100 meters.
22.98 seconds, 23.09 seconds, 23.06 seconds, 22.83 seconds
What is the difference between her best time and her worst time?
A.
0.03 second
B.
0.23 second
C.
0.11 second
D.
0.26 second
Answers
The difference between her best time and her worst time is equal to 0.26 seconds.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
Jodie has to swim for 100 meters. The four of her times to cover this distance are 22.98 seconds, 23.09 seconds, 23.06 seconds, 22.83 seconds.
Let's find the time per sec to swim at each instances.
So ,
100 meters in 22.98 seconds meant :
= 100 / 22.98
= 4.35 m/sec
Similarly ,
100 meters in 23.09 seconds meant :
= 4.33 m/sec
100 meters in 23.06 seconds meant :
= 4.34 m/sec
100 meters in 22.83 seconds meant :
= 100 / 22.83
= 4.38 m/sec
So , we can find out that Jodie swims distance of 100 meters fastest on speed of 4.38 m/sec in 22.83 seconds and slowest on speed of 4.33 m/sec in 23.09 seconds.
The difference between her best time and her worst time is :
= 23.09 - 22.83
= 0.26 seconds
Therefore , the difference between her best time and her worst time is equal to 0.26 seconds.

Answers
Answer:
Graph 1: perfect negative correlation
Graph 2: modest negative correlation
Graph 3: modest positive correlation
Graph 4: strong positive correlation
Graph 5. weak negative correlation
Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.

M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.

If there is no remainder, find the largest possible number of sweets in each tray.
Answers
Answer:
the largest possible number for each would be dividing it by two so 36 divided by two is 18 and 44 divided by two is 22
so for the orange the largest number would be 18

m = money (total cost)
The system of equations that represents the situation is yx = y.

The system is yx = y, since the amount of dollars per hour multiplied by the amount of hours, plus any amount (if needed) will equal the total amount of money that Jada and/or Andre receives.
