In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people.
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars

If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars

Which shows the graph of the solution set of y < 1/3 x – 2?

AnnZ [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y< \frac{1}{3}x-2$

The solution of the inequality is the shaded area below the dashed line

The equation of the line is $y= \frac{1}{3}x-2$

The slope of the line is positive $m= \frac{1}{3}$

The y-intercept of the line is the point $(0,-2)$

The x-intercept of the line is the point $(6,0)$

A skydiver weighing 180lbs (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute a

Annette [7]

For the presented problem, the solution would be v(0)=0v(0)=0 isv(t)−mgb=e−b/m⋅t(v0−mgb)⟺v(t)=mgb(1−e−b/m⋅t)≈g⋅t−gb2m⋅t2, with the following given, 
m=180[lb]=81.6[kg]

g=9.81[m/s2]

b=0.75[kg⋅m/s2⋅s/ft]=0.2286[kg/s]

The solution that the friction provides is v(t)=3501.7[m/s]⋅(1−e−0.00280[1/s]⋅t), where I get 96.69[m/s]=317.2[ft/s]. I am hoping that this answer has satisfied your query about this specific question.
