Answer:

a) 320 students

b) 25 students

Step-by-step explanation:

Number of 18-years old in the survey:

(We add all  frequency points for each line)

0 + 30 + 20 + 60 + 70 + 40 + 60 + 40 + 0 = 320 students

Number of 18 year old spending between 25 and 35 minutes: 40 + 65 = 105

Number of 12 year old spending between 25 and 35 minutes: 30 + 50 = 80

105 - 80 = 25 students

DiKsa [7]

Answer: Yes, Rita has enough wire to hang the picture frame.

She need wire only to hang the picture frame which 8 cm away from the nail, and she has 26 cm of wire to hang it .

A magazine advertises that a subscription price if $29.99(for12 issues) represents a savings of 70% from the newsstand price.Wha
Ede4ka [16]
$29.99 is the final price.
"y" is the original price.
Subtract the savings from the original price to get the final price of $29.99.
70% = 70/100 = .70
y - (y x .70) = 29.99
y - .7y = 29.99
.3y = 29.99
.3y/.3 = 29.99/.3
y = 99.96667
y = $99.97 (rounded)
