Answer: 4
Step-by-step explanation: Using Sine, Cosine, and Tangent, you use 8 as the hypotenuse and put your 60 w/ you Cos, so it will read cos60*=adj/8. Then you'll multiply both sides by 8, so it will be 8*cos60=adj. So, the cosine of 60 is 1/2, you multiply that by 8, then that equals 4, I hope that helps!

Answer:
Radius, r = 6 inches
Step-by-step explanation:
We have,
Volume of a cone is 565.2 cubic inches
Height of the cone is 15 inches
It is required to find the radius of the cone. Volume of a cone is given by :
r is radius of cone
So, the radius of the cone is 6 inches. The correct option is (b).
Answer:
mean=13.2
median=13
mode=14
Step-by-step explanation:
mean=sum of values/number of values
sum of values=9+17+14+12+14+14+9+11+10+20+10+22+11+11+9+15+14+15=237
number of values=18
mean=237/18=13.17
Mean=13.2
Arranging data in ascending order
9 9 9 10 10 11 11 11 12 14 14 14 14 15 15 17 20 22
n/2=18/2=9 is an integer so,
median= the average of (n/2)th and (n/2 +1)th observation
median=(12+14)/2=26/2=13
Median=13
Mode= The most repeated observation in the data
14 is repeated more than other numbers so, 14 is the mode for this data.
Mode=14
