Answer:
D
Step-by-step explanation:
Open circle means less than or greater than, and the dot is on -5, so the answer is greater than -5
Answer:
Option A is correct.
Step-by-step explanation:
The formula used for finding the volume of right cone is:
Volume of Right cone = (1/3)π.r².h
We need to find altitude i.e h
Volume of cone=V = 8579 m^3
Radius=r = 16m
Altitude =h =?
Putting values,
8579 = (1/3) * 3.14 * (16)^2*h
8579 = 1/3 * 3.14 * 256 *h
8579 = 267.95 * h
=> h = 8579/267.95
h = 32.0 m
So, Altitude of right cone is 32.0 m
Option A is correct.
Substitute 3x+1 for x. Then solve from there
Answer:
<em>Bethany did not do better than Richie because her average score was less than his.</em>
Step-by-step explanation:
<u>Average Value</u>
The average or mean value of m successes out of n tries is given by:
![\displaystyle \bar x=\frac{m}{n}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cbar%20x%3D%5Cfrac%7Bm%7D%7Bn%7D)
During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:
![\displaystyle \bar x=\frac{12}{15}=0.8](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cbar%20x%3D%5Cfrac%7B12%7D%7B15%7D%3D0.8)
Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:
![\displaystyle \bar x=\frac{8}{11}=0.72](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cbar%20x%3D%5Cfrac%7B8%7D%7B11%7D%3D0.72)
Bethany did not do better than Richie because her average score was less than his.
