1. A poll asked 15 men in two age groups, 40 and younger and older than 40, whether they watched the Super Bowl or not The results are recorded in the table.

(a) Create a two-way table of the data. Of the men surveyed, how many were older than 40? How many men did watch the Super Bowl?
(b) Create a two-way relative frequency table that displays the relative frequency of men who did watch and men who didn’t watch that are 40 and younger and of the men older than 40. (hint -use watched or didn’t watch row/column as your complete set). Express your answers as decimals written to three decimal places.
(c) What percentage of men with watched the Super Bowl that are older than 40?

a is the correct

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.

it is 10.6 according to my calculations
