Answer:

C

Step-by-step explanation:

The equation of a line is y=mx+b where m is slope and b is the y-intercept. the y-intercept is where the line crosses the y-axis which is at (0,2) here so b=2.

The slope is found by finding the difference between any two points on the line. To find the difference, choose two points which cross through two grid lines. The only points on this graph which does that is (0,2) and (10,15). Find the slope by subtracting 15-2 / 10-0. This is equal to 13/10 or 13 over 10.

The equation is y = 13/10 x +2.

vesna_86 [32]

Answer:

110 students

Step-by-step explanation:

The number of students who have only taken calculus is given by the number of students who have taken calculus minus the students who have taken both classes:

C =100 -50\\C= 50\ students

The number of students who have only taken discrete mathematics given by the number of students who have taken discrete mathematics minus the students who have taken both classes:

D =110 -50\\C= 60\ students

The number of students that have taken a course in either calculus or discrete mathematics is:

E = C+D = 50+60\\E= 110\ students

Svetradugi [14.3K]

Answer:

4.5 \times 10^{9} tons.

300 times.

Step-by-step explanation:

Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.

So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e. 4.5 \times 10^{9} tons. (Answer)

Now, this amount is larger than 1.5 \times 10^{7} by \frac{4.5 \times 10^{9} }{1.5 \times 10^{7}} = 300 times. (Answer)
