Volume of the cone is 17 cm³
Step-by-step explanation:
- Step 1: Volume of a cone = 1/3 πr²h. Find volume of the cone where r = 2 inches and h = 4 cm.
Volume = 1/3 × 3.14 × 2² × 4
= 16.75 cm³ ≈ 17 cm³ (rounding off to nearest whole number)
Due to the distance formula the answer should be root 113 or 10.63
Answer:
Step-by-step explanation:
We are given the following in the question:
Population D:
30% of the turtles have a shell length greater than 2 feet.
Sample size,
Number of turtles that had shell length greater than 2 feet,
Sample proportion:
Population E:
20% of the turtles have a shell length greater than 2 feet.
Sample size,
Number of turtles that had shell length greater than 2 feet,
Sample proportion:
We have to find the difference between the sample proportion.
Difference in sample proportion =
Answer:
-1=-2
4=-7
Step-by-step explanation:
for x=-1
y=(-1^2)+(2*-1)+1
y=-1-2+1
y=-2
for x=1
y= (-1^2)+(2*1)+1
y= -1+2+1
y=2
for x=4
y=(-4^2)+(2*4)+1
y=-16+8+1
y=-7
