The heights (in inches) for a sample of 21 male adults are
62, 82, 79, 76, 73, 70, 67, 64, 61, 80, 79, 60, 60, 71, 71, 71, 74, 74, 74, 75, 75
draw the frequency polygon for these data using an initial class boundary of 59.5, an ending class boundary of 84.5 and 5 classes of equal width. note that you can add or remove classes from the figure. label each class with its midpoint.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

pls mark as brainliest.

just get this app called photo math it should be able to do those
