In 2010, there were 30 million people over 65 years of age out of a population of 313 million. by 2050, it is estimated that there will be 87 million people over 65 years of age out of a population of 439 million. would your chances of meeting a person over 65 at random be greater in 2010 or 2050? explain.
1.
the chances are greater in (2010 or 2050)
because the relative frequency probability of meeting a person over age 65 in 2010 is
and the relative frequency probability of meeting a person over age 65 in 2050 is
(round to the nearest thousandth as needed.)

(a) 2050

(b) 0.09

(c) 0.19

Step-by-step explanation:

Frequency probability of meeting a person over age 65 in 2010:

people over age of 65 = 30 million

Total population = 313 million

Frequency probability =

=

= 0.09

Frequency probability of meeting a person over age 65 in 2050:

people over age of 65 = 87 million

Total population = 439 million

Frequency probability =

=

= 0.19

∴ The frequency probability of meeting a person over age 65 in 2050 is greater than the frequency probability of meeting a person over age 65 in 2010.

                                    0.19 > 0.09

So, there are greater chance in 2050 for meeting a person over the age of 65.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

it would take 7/10 of an hour too fill the pool.
