Step-by-step explanation:
Answer:
-3/4
Step-by-step explanation:
You could identify two points and used the slope formula given two points.
OR
You can just count from one point to another.
First step: Identify two points where the line crosses nicely.
I see one at the y-intercept (0,1) and another at (4,-2). So starting at the y-intercept, how much do we need to travel down to get to (4,-2). Hopefully you say down 3, so the rise is -3. Now how much to the right after traveling down 3 from (0,1) to we need to travel to get to (4,-2) . Count the spaces...4 units right so the run is 4.
The slope is -3/4
<span>A: The middle 95% contain between 23.8 and 24.2 oz.(2 SDs under and over the mean)
B: Approximately 68% of boxes have between 23.9 and 24.1 oz of cereal (1 SD under and over the mean)
C: 2.5% of boxes contain more than 24.2, because 95% are within 2 SDs, and that includes lower and higher extremes.
D: 16% of boxes have more than 24.1, because 68% are within 1 SD of the mean, so 32 are left, and that includes lower and higher extremes.</span>
Answer:
Simple interest is calculated based only on the principal balance, whereas compound interest is calculated based on the principal balance and the accumulated interest from the previous periods. This means compound interest will make the amount owed grow at a much faster rate than simple interest.
Hope this helps!!!
Step-by-step explanation:
1)
V=hpr^2
r=√(V/(hp)), using 216p for V and 3 ft for h you get:
r=√(216p/(3p))
r=√72
r≈8.5 ft (to nearest tenth of a foot)
2)
The volume of these ice cream cones is half the volume of a sphere plus the volume of a cone...
V=((4pr^3)/3)/2+(hpr^2)/3
V=(4pr^3)/6+(hpr^2)/3
V=(p/3)(2r^3+hr^2)
And the difference between them is:
V=(p/3)(2R^3+HR^2-2r^3-hr^2), given R,H,r,h=3,12,2,8:
V=(p/3)(2*27+12*9-2*8-8*4)
V=(p/3)(114)
V=38p cm^3
V≈119.38 cm^3 (to nearest one-hundredth of a cm^3)
3)
V=[(4pr^3)/3]/2
V=(2pr^3)/3 and when r=15yd
V=2250p yd^3
V≈7068.58 yd^3 (to nearest hundredth of a yd^3)
