Answer: C) Next year, 7 out of every 60 students will be taking music.
Step-by-step explanation:
A is wrong because it is an opinion which a table cannot prove.
B is wrong because it says "A representative sample of 60 students) while the answer incorrectly says 30.
C is correct because on the table it says 7 people are taking music and correctly identifies that it's out of 60 students.
D is incorrect for the same reason B is incorrect except this time it says 120.
Answer:
Step-by-step explanation:
cos 43=cos (90-47)=sin 47
I think it will be set up as 2000(.051)^3
Answer:
Step-by-step explanation:
2(x-1)=50, lets multiply
2x-2=50 add 2 in both sides
2x=48
x=24
your options are weird, unless you mean (x-1)^2 ?
Answer: Volume = 174.71 cubic meters
Step-by-step explanation:
Hi, to answer this, first, we have to apply the formula for the circumference (C) of a circle.
C= 2πr
Substituting with c=19.4 in the formula, and solving for the radius (r)
19.4= 2πr
19.4/ 2π =r
r= 3.09
Finally we apply the formula:
Volume of a right circular cone: 1/3 π r^2 h
Where h is the height of the cone and r is the radius of the base.
Replacing with the values given and calculated:
V=1/3 π (3.09)^2 (17.5)
V = 174.71 cubic meters
