Someone please help me with this!! <3

Um, your sum should be 4.

Step-by-step explanation: The sum of an infinite geometric series can be found using the formula where a is the first term and r is the ratio between the successive terms.

For , find the first term in the series by substituting in the lower bound and simplifying: a=1.

For r, find the ratio of successive terms by plugging into the formula and simplifying: .

For 1–r, substitute the values of the ratio and first term into the sum formula: ; ∴, your sum should be 4.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
