Answer:
$26
Step-by-step explanation:
? times .8 (80%) = 20.80
reverse that and you get 20.80 / .8 (80%) = ?
The answer you get is 26 dollars. Tadah!!!

Answer:
95% confidence interval for nasturtiums in a 50 gram bag is (1.442, 1.700)
Step-by-step explanation:
The sample is:
1.45g, 1.35g, 1.45g, 1.65g, 1.72g, 1.45g, 1.35g, 1.92g, 1.76g, and 1.61g.
Sample size is 10
Mean nasturtiums in a 50 gram bag is
Standard deviation of the sample is the mean of the squared differences from the mean(0.181)
95% Confidence Interval can be calculated using M±ME where
- M is the mean nasturtiums in a 50 gram bag (1.571 g)
- ME is the margin of error from the mean
And margin of error (ME) can be calculated using the formula
ME= where
- t is the corresponding statistic in the 95% confidence level and 9 degrees of freedom (2.262)
- s is the standard deviation of the sample (0.181)
- N is the sample size (10)
Then ME= =0.129
95% confidence interval for nasturtiums in a 50 gram bag is 1.571±0.129
The volume of a cone is 1/3 the volume of a cylinder
Answer:
this answer requires that you do a little solving to find all the dimensions we need for the volume.
We know that H (height) = 2m
Diameter = 5 x height, so
Diameter = 5 x 2m = 10m
If you have the formula for finding the volume of a cylinder, it is basically the area of the circular base x cylinder height. You may know already that the area of a circle is (pi) x radius2
So this will be 2 (the height) x (pi) x r2
As we just figured out, the DIAMETER is 10, so the radius is half the diameter = 5.
This brings our volume to 2 x (pi) x 52
= 2 x (pi) x 25
2x25 = 50, so we have 50 x (pi).
Pi = 3.14
50 x 3.14 = 157
And don't forget your units = 157 m3
