$3.50 because 14 - 75% or you should do convert 75% to a decimal .75 so u should do

Last year there were 205 ducks living on the pond. This year there are 20% more ducks living on the pond. How many ducks are living on the pond this year? *
~5 points
~164 ducks
~225 ducks
~246 ducks
In the above question, what was the original amount of ducks?
~205
~20
~246
~164

Answers

Answer:

246

Step-by-step explanation:

246. Step 1) Calculate 20 percent of 205: To calculate 20 percent of 205, you multiply 20 by 205 and then divide the product you get by 100. Here is the math to illustrate:

20 x 205 = 4100
4100 / 100 = 41

Step 2) Add the 20 percent you calculated in Step 1 to 205. Here is the math to illustrate:

205 + 41 = 246

Therefore, the answer to "What is 205 plus 20 percent?" is:

Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.

What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?

3.5
3.25
0.75
0.25

Answers

Answer:

0.25

Step-by-step explanaition:

The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird in feet per second?

Answers

Answer:

[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]

Step-by-step explanation:

Given

[tex]Altitude\ Change = -4\frac{1}{4} \ ft[/tex]

[tex]Time = 2\frac{1}{2}\ s[/tex]

Required

Determine the average change

This is calculated as follows:

[tex]Average\ Change = \frac{Altitude\ Change}{Time}[/tex]

This gives:

[tex]Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}[/tex]

[tex]Average\ Change = -4\frac{1}{4}/2\frac{1}{2}[/tex]

Convert to improper fractions

[tex]Average\ Change = -\frac{17}{4}/\frac{5}{2}[/tex]

Convert to multiplication

[tex]Average\ Change = -\frac{17}{4}*\frac{2}{5}[/tex]

[tex]Average\ Change = -\frac{17}{2}*\frac{1}{5}[/tex]

[tex]Average\ Change = -\frac{17}{10}[/tex]

[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]
