Wouldn't 44 be 12/20 bcuz they say at least which is greater than or equal to?

Good afternoon sir for number 5 I did it another way I put 90 over 60 and times by 100 which is 150 and then I times 4/5 with the 150 and get the answer is it ok either way.

[@TimoyWhite]

yes

[@ShamarGT]

Ok sir

[@DinishaJoseph]

D

[@ericfelix152]

44 is incorrect. The cumulative frequency curve is a "less than" curve. The correct choice is C .

How did you get the 560 for number 4

[@diamondking2514]

he didn't?

[@roxannebenjamin633]

4) $560 was shared in the ratio of (2:3:9) right? •First you have to subtract (minus) the smallest share in the ratio which was 2 from the largest share in the ratio which was 9. ~ 9-2 =7 Your answer is 7. • Second step... Add up the ratios, (2:3:9) 2+3+9 = 14 Your answer is 14 • Third Step... The answer you got from adding up the ratios which was 14... It is equal to the number that was being shared which was $560. 14 = 560 *We don't know the number that was given to the largest number in the ratio which is 9 so the symbol for the absent number would be the letter "n" ~Now divide both sides by 14 14n÷14 = $560÷14 *Cancel (cross out) the 14's that are divided by each other. Now we are left with n = $560÷14 n = 40 Now do you remember the answer we got when subtracted (minused) 2 from 9? We got 9 - 2 = 7 •Last step...we multiply 40 × 7. Your answer is $280. That's the answer for number 4) Sorry if this was too much of an explanation. zaijiàn

Video not clear enough

[@lorianncole3695]

Pause the video then look at the top right corner there are 3 vertical dots click it and there will be options of what to use, press the one which says 'Quality' and choose from the numbers you prefer Or just click the last one which is 1080p (that is better)

[@Djfr]

Loriann Cole omg your a scientist thank you very much

[@SamanthasJamaicanSkinCare]

You dont explain

[@fiazmohammed549]

Number 14 was quite obvious and easy, and he does explain
