Answer:
260 mph
Step-by-step explanation:
With the information given, we know the plane traveled 650 miles in 2.5 hours
To find the speed, do distance/time
650 ÷ 2.5 = 260
= 260 mph
Answer:
Mean - 89
Median - 90.5
Mode - 89 or 92
Q1 - 84.5
Q3 - 96.5
IQR - 12
Step-by-step explanation:
A mean is an average. Just add all numbers then divide by how many numbers there are.
A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.
A mode is the number that appears most often. Count how many of each number there is.
Q1 is the middle of the lower half of the data.
Q3 is the middle of the upper half of the data.
IQR is the difference between Q3 and Q1. (subtract)
Answer:
9.43 cm³
Step-by-step explanation:
Given that the surface area of the spherical scoop is 36π cm², we find its radius. The surface area of a sphere, A = 4πr² where r = radius
36π cm² = 4πr²
r² = 36π cm²/4π
r² = 9 cm²
r = √(9 cm²)
r = 3 cm
So, the volume of the spherical scoop of ice cream is thus V = 4πr³/3
= 4π(3 cm)³/3
= 4π(9 cm³)
= 36π cm³
The volume of the ice cream cone is V' = πr²h/3 where r = radius of cone = radius of spherical scoop = 3cm and h = height of cone = 11 cm
V' = π(3 cm)² × 11 cm/3
= 9π cm² × 11 cm/3
= 33π cm³
So, the volume of ice cream that will overflow is thus V - V' = 36π cm³ - 33π cm³
= 3π cm³
= 9.43 cm³
