The estimate is an over estimate because 2.19 time 6 equals 13.14 and you sya 15 dollors so so it it is an over estimate
The answer is x =14/5
2x+5-x=3 (2×-3)
distribute the 3.
2x + 5 -x = 6x -9
Combine like terms on the left.
x +5 = 6x -9
Subtract the 6x term from both sides.
-5x + 5 = -9
Subtract the 5 to both sides.
-5x = -14
Divide both sides by -5.
x = 14/5
<u>Change</u> of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.
When the box hits the bottom, it has 980 joules <u>less</u> PE than it had
before it started dropping.
(As well as 980 joules <u>more</u> kinetic energy.)
In order to make a frequency plot first we need to find the proportion of each outcome.
Total number of results = 15+20+5+5+5 = 50
Frequency of 0 = 15
Proportion of 0 = 15/50 = 0.3
Frequency of 1 = 20
Proportion of 0 = 20/50 = 0.4
Frequency of 2 = 5
Proportion of 2 = 5/50 = 0.1
Frequency of 3 = 5
Proportion of 3 = 5/50 = 0.1
Frequency of 4 = 5
Proportion of 4 = 5/50 = 0.1
Now we need to plot the data on a frequency plot. The x-axis shows the outcomes from 0 to 4 and y-axis shows the frequency of each outcomes. The frequency plot is shown in the figure attached with.
Answer:
i think the answer is a) 9/5
