In a class of 100 students , 40 offer Biology and 10 offer Chemistry and Biology . 10 offer Physics and Chemistry , and 30 offer Physics and Biology . Each student offers at least one of the three subjects . The number of students who offer Biology is equal to those who offer Physics only and the sum of the number of students who offer Biology and those who offer Chemistry is equal to the number of students who offer Physics . a) Illustrate the information on a Venn diagram
b) Find the number of students who offer
i) Chemistry only
ii) only two subjects
¡¡¡) only one subject
iv) Physics
v ) Chemistry
vi) Chemistry and Physics only

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
