Which function will have the steepest graph? y = –2x y =-1/2 x y = 3/2x y =5/2 x

timofeeve [1]

The steepest graph is gonna have the largest slope....but u have to use the absolute value of the slopes to compare

y = -2x.....slope is -2....| -2 | = 2
y = -1/2x...slope is -1/2....| -1/2 | = 1/2
y = 3/2x....slope is 3/2 (or 1 1/2)...| 1 1/2} = 1 1/2
y = 5/2x...slope is 5/2 (or 2 1/2)...| 2 1/2| = 2 1/2

so the steepest graph is : y = 5/2x

An epidemiologic survey of roller-skating injuries in Metroville, a city with a population of 100,000 (during the midpoint of th

Ahat [919]

Answer: c. $\dfrac{90}{1800}\times100\%$

Step-by-step explanation:

As per given , we have

Total number of residents injured from roller-skating =1,800

Total number of deaths from roller-skating = 90

Formula for Mortality rate : $Mortaility\ rate= \dfrac{Deaths\ due \ to\ injury}{Tota\ injuries}$

Then, the proportional mortality ratio (%) due to roller-skating was

= $\dfrac{90}{1800}\times100\%$

= 5%

Hence, the correct answer is c. $\dfrac{90}{1800}\times100\%$

Answer:

Check the explanation

Step-by-step explanation:

Open file in excel.

Click on Data->Data Analysis and select Regression.

Enter wait time data range in y-variable.

Enter Duration data range in x-variable.

Click ok.

From above output:

#1 The equation of the linear regression line is:

A 95% confidence interval for the slope of the regression line is:

${(10.110,11.349)}$

In excel, ise formula =FORECAST(6,wait time data range, duration data range) and press enter. The wait time between eruptions following a 6 minute eruption is $\hat{Y}_{x=6}= 97.9} .$

Since (for F test) $p-value=0.000$ , we can conclude that there is a statistically significant linear relationship between the duration of the eruptions and the wait time between eruptions.
