Answer:  0.8

Step-by-step explanation:

From the given picture, it can be seen that there is a right triangle,

Such that the side opposite to right angle (hypotenuse) =10 units

By using trigonometry , we get

\sin(53^{\circ})=\dfrac{\text{side opposite to } \sin(353{\circ})}{\text{Hypotenuse}}\\\\\Rightarrow\ 0.79863551004=\dfrac{x}{10}\\\\\Rightarrow\ x=10\cdot0.79863551004\\\\\Rightarrow\ x07.9863551004\approx8.0\ units

Hence, the value of x to the nearest tenth = 0.8 units

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
