Step-by-step explanation:
Sin-495 = 0.98
cos-495 = 0.19
tan-495 = 4.95
sin<span>-20π/3</span> = 0
cos<span>-20π/3</span> = 0.3
tan<span>-20<span>π/3</span></span> = 0
Answer:
Step-by-step explanation:
a) Complete the table
Monday Tuesday Wednesday Total
Female 21-14=7 38-13-7= 18 13 38
Male 14 33-18= 15 26-13 =13 80-38=42
Total 80-33-26= 21 33 26 80
b) P(the student is a female) = 38/80= 0.475
c) P(the student visited the library on Tuesday) = 33/80= 0.4125
<span> it's 2x3.14 times 6 times 18
</span><span>2π(6)(18)</span>
6x^2- 8x -8 will be the answer
