Answer:
The sum of the probabilities is greater than 100%; and the distribution is too uniform to be a normal distribution.
Step-by-step explanation:
The sum of the probabilities of a distribution should be 100%. When you add the probabilities of this distribution together, you have
22+24+21+26+28 = 46+21+26+28 = 67+26+28 = 93+28 = 121
This is more than 100%, which is a flaw with the results.
A normal distribution is a bell-shaped distribution. Graphing the probabilities for this distribution, we would have a bar up to 22; a bar to 24; a bar to 21; a bar to 26; and bar to 28.
The bars would not create a bell-shaped curve; thus this is not a normal distribution.
Answer:
y= -69/8 (negative 69 over 8)
Step-by-step explanation:
First, you have to simplify both sides of the equation:

Second, add 3/4 to both sides:
-2/3y +-3/4 + 3/4=5 +3/4
-2/3y= 23/4
Next, multiply both sides by 3/(-2) (3 over -2)
(3/-2)*(-2/3y)= (3/-2) * (23/4)
<em><u></u></em>
<em><u>y= -69/8</u></em>
Answer:
<u>Length of 1 piece= Length of total divided by 8</u>
Step-by-step explanation:
Length of total= 5.24 feet long
Width of total= 1.34 feet wide
Width is divided by 1 line so, there are 2 parts.
Width= 1.34 divided by 2
Width= 0.67 feet wide
Length is divided by 7 lines, so there are 8 parts.
Length= 5.24 divided by 8
Length=0.655 feet long
They are asking for formula to find the length of each piece
<u>Length of 1 piece= Length of total divided by 8</u>
<u></u>
Hope that helps!
Answer:
Y=4x+9
Step-by-step explanation:
Use rise over run to find 2 points for the slope. B is as simple as looking where the line passes y.
He saves $200 (the amount of change over the original amount $500
200/500 = 2/5 and 2/5 = 40% (divide 2 by 5 and get .4 which = 40%)
40% discount is the answer to your question
