Answer:

slope of the given straight line in graph is -2

Step-by-step explanation:

<u>Explanation:</u>-

in given graph we have to choose points are A(0,3) on y-axis and B(1.5 , 0) on x- axis

let m be the slope of a line

by using slope formula is

m= \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

m = \frac{0-3}{1.5-0}

m= -2

<u>another points we have choose</u>

in given graph we have to choose points are A(0,3) on y-axis and B(2.5 , -2)

<u>slope of a line</u> :-

let m be the slope of a line

by using slope formula is

m= \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

m = \frac{-2-3}{2.5-0}

m= -2

where ever you will take point the slope of given straight line is

m = -2

Since the Boston marathon began in 1897, the finish time has been incrementally decreasing. The mean finish time to date is 231
morpeh [17]

Answer:

hello your question lacks the required options but i will provide a general answer to your question

answer : The mean value  and the standard deviation would allow us use a Z-score

Step-by-step explanation:

mean value = 231 minutes

standard deviation ( std ) = 40 minutes

sample size = 40

The parameters that would be applicable while use Z-score are : The given mean value and the standard deviation

This is because the value of a z-score gives us an information on how far we are from the mean score i.e. number of standard deviations

+Zscore means that the score  is above the average value

-Zscore means that the score is below the average value

-2(x-5)=6(2- 1/2x)<br><br> Please show your work. Distributive property, remove variable
schepotkina [342]

The solution of given equation is x=2

Further explanation:

In order to solve the given equation we have to isolate the variable x on one side of the equation. The process will involve distributive property and simplification.

Given:

-2(x-5)=6(2-\frac{1}{2}x)\\Apply\ distributive\ property\\-2x-2(-5)=(6)(2)-(6)(\frac{1}{2}x)\\-2x+10=12-\frac{6}{2}x\\-2x+10=12-3x\\-2x+3x=12-10\\x=2

The solution of given equation is x=2
