Answer:
199 a 426 students
Step-by-step explanation:
first to see what amount we are talking about in each case, let's see how many students each percentage represents
22% of students: (22 * 1420 students) /100 = 312.4 students
8% of students: (8*1420 students)/100 = 114.6 students
that is, that the average number of students who work part time is 312.4 students. And that number can vary up to 114.6 students above and up to 114.6 students below
that can be expressed as
22% + 8% = 312.4 + 113.6 = 426 students
and
22% -8% = 312.4-113.6 = 198.8≅ 199 students

Answer:
non-linear for the first one
-2 or linear either option should work this is for the second
Step-by-step explanation:
Given:
1st map = 8 cm
2nd map = 6 cm
1 cm in the map is equal to 2 km on the actual trail.
8 cm * 2km/1cm = 16 km is the actual length of the trail in the first map
6 cm * 2km/1cm = 12 km is the actual length of the trail in the second map.
I'm not sure on how to get the scale factor from the map to the actual trail. I'm confused if I had to consider cm and km because 1km is equal to 100,000 cm.
Proportion of the second map to the first map is 6/8
6/8 = x/3 → 6*3 = 8x → 18/8 = x → 2.25
6/8 = x/4 → 6*4 = 8x → 24/8 = x → 3
6/8 = x/5 → 6*5 = 8x → 30/8 = x →3.75
The side measure of the triangle in the second map is only 75% of the side measure of the triangle in the first map.
Answer:
<em>149</em>
Step-by-step explanation:
- 4, - 1, 2, 5, ...
= - 4
d = 
- = - 1 - (- 4) = 3
= + (n - 1)d
= - 4 + (52 - 1)(3) = <em>149</em>
