Step-by-step explaination
All you need to do is find the frequency of the test scores.
70 = 2 dots
75 = 0
80 = 3 dots because there are 3 students that got a 80 %
85 = 3 dots because there are 3 students that got a 80 %
90 = 4 dots because there are 4 students that got a 90 %
95 = 3 dots
100+ = 0 dots
Answer:
21 N
Step-by-step explanation:
let mass be m and weight be w
Given w varies directly with m then the equation relating them is
w = km ← k is the constant of variation
To find k use the condition m = 7 , w = 49 , then
49 = 7k ( divide both sides by 7 )
7 = k
w = 7m ← equation of variation
When m = 3 , then
w = 7 × 3 = 21 N
Answer:
draw a number line from 66 to 81
make your minimum 67
lower quartile should be on 70
the median on 77
upper quartile and maximum on 80
(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)
You can search up "box plot" and go on images to see what i mean

Step-by-step explanation:
I can probably help on part 4 and send a sketch but I currently can't use my phone to send a pic and I am currently on my desktop :'(
I rlly hope you do well! Don't lose hope! <3
(also like ur pfp, i enjoyed the anime too ahehe)
<span>y-6=-2 (x-7)
Start by distributing..
y - 6 = - 2x + 14
Add 6 to both sides...
y = - 2x + 20
Slope of this equation is -2</span>
