If f(x)=2x^2-10, find f(-3)
Maurinko [17]

Answer:

f(- 3) = 8

Step-by-step explanation:

To evaluate f(- 3), substitute x = - 3 into f(x) , that is

f(- 3) = 2(- 3)² - 10 = 2(9) - 10 = 18 - 10 = 8

What is 15 cm/year converted to inches per month? Round to the nearest tenth.
topjm [15]

Answer:

0.5 inches per month

Step-by-step explanation:

There are nearly 0.3937 inches in 1 cm, so

1 \ cm \approx 0.03937 \ in\\ \\15\ cm\approx 5.9055\ in

There are 12 months in the year, so'

15 centimeters per year is equivalent to

15 \ cm/year\approx \dfrac{5.9055}{12}\ in/month\\\approx 0.492125\ in/month\\\approx 0.5\ in/month\\\\

Of great importance to residents of central Florida is the amount of radioactive material present in the soul of reclaimed phosp
alukav5142 [94]

Answer:

See figure attached and explanation below.

Step-by-step explanation:

For this case we have the following dataset given:

0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99, 0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06, 12.48

And for this case we can use the followinf R code to create the frequency histogram.

> x<-c(0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99,0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06,12.48)

> length(x)

[1] 25

> hist(x, prob=TRUE)

And for this case we have the histogram on the figure attached. For the number of classes we use the formula of sturges:

k = 1 +3.322 log (n)= 1+3.3 log(25)= 5.61

And for this case we have approximately 6 classes. And that's what we can see on the figure attached

As we can see most of the values are on the left so then we have a right skewed to the right and the distribution is assymetrical, with most of the values between 0 and 6
