You could use a ratio form for the first question
4) 8.5 : 34
29.75 : x x is the unknown
To find x, you must divide 29.75 by the length 8.5 to find the amount needed to be multipled by 34 grams, to find the total grams needed for the length of 29.75
29.75 / 8.5= 3.5 34 x 3.5 = <u>119 grams</u> , which is the answer to 4)
5) Same for this question, use the ratio form
1 1/3 : 3/4 5 / 0.75 ( 3/4) = 6.7
x : 5 miles 6.7 x 1 1/3 = <u>8.91 Miles jack ran</u>
6) ?? (Question not shown)
7) n = 0.6
8) 1 patient : 25 mins
n patients : 7.5 hours
25 mins to hours = 0.4
1 : 0.4
n : 7.5 7.5 /0.4 = 18.75 ----> <u>19 patients</u>
A joint relative frequency is found by dividing a frequency that is not in the Total row or the Total column by the frequency's row total or column total
If it takes 1 hour to go 40 miles, then if you multiply 40 by 3, ( 3 being the amount of hours ) you would have 120. ( the amount of miles it takes for Javier to get to his grandmother. ) So, because there is only a 2 hour difference between 7 AM and 9 AM, it would be unreasonable for Javier to be in his grandmothers city. But, it WILL be reasonable for Javier to be in his grandmothers city by 10 AM.
Answer:
no since 18+16=34<35 it must be greater than 35
