Answer:

6 weeks

Step-by-step explanation:

Set up a proportion where x is the amount of time with 12 pupils:

\frac{4}{2} = \frac{12}{x}

Cross multiply and solve for x:

4x = 24

x = 6

So, it will take 12 pupils 6 weeks to complete the job.

Katena32 [7]

Answer:

60.5%

Step-by-step explanation:

60% white, 40% black

The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

It says write an equation of the line shown and the line goes through points 4,3 and 1,-3
RUDIKE [14]
Slope of the line;
slope=\frac{change in y}{change in x}
Slope=\frac{3--3}{4-1}
Slope,m =\frac{6}{3} =2
y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
