First calculate the percentage of math.
100-23-30-15-12
=20%
then 150x20% for the math
=30 so there are 30 students chose math.
Answer:
4,00 pounds
Step-by-step explanation:
The equation of line that passes through the points (-3,-1) and
(-6,3) is:

Step-by-step explanation:
Given points are:
(-3,-1) =(x1,y1)
(-6,3)=(x2,y2)
The slope-intercept form of equation of line is:

We have to find the slope first
Putting the value of slope in the slope intercept form

To find the value of b, putting the point (-3,-1) in the equation

Putting the values of b and m

The equation of line that passes through the points (-3,-1) and
(-6,3) is:

Answer:
Step-by-step explanation:
if r=1 perfect positive correlation.
if r=-1 ,perfect negative correlation.
r=0 ,no correlation.
r=.02 ,so D
well, if look at the timetable, She got the 08:30am train from Aberystwyth and arrives on time at Shrewsbury, from the timetable we know she arrived at 10:17am, now she did some rigamarole and got back to the Train station at Shrewsbury 4 hours later. Well, we know she arrived at 10:17am, if we add 4 hours to that that'll make it 1417 or namely 2:17pm.
well, the Train arrives at Shrewsbury a 14 19, or 2:19pm, she is there at 2:17pm, so she's really 2 minutes before the Train arrives at Shrewsbury, she's right on time, possibly with some munchies too.
14 19 > 14 17.
