Curiously, during months when sales of beer are above average, sales of ice cream also tend to be above average, and during months when sales of beer are below average, sales of ice cream also tend to be below average. which of the following can we conclude from these facts? (a) for a lot of people, drinking beer causes a desire for ice cream, and vice versa. (b) the correlation between "beer sales" and "ice cream sales" is negative.(c) a scatterplot of monthly beer sales vs. monthly ice cream sales would show a horizontal line pattern. (d) there may be a lurking variable causing higher beer and ice cream sales during some months and lower beer and ice cream sales during other months

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
