This is a direct proportionality question
the pounds of apples needed is directly proportional to the number of apple pies made
to make 5 apple pies , 2 pounds of apples are needed
then to make 1 apple pie - 2/5 pounds of apples are needed
therefore 1 apple pie requires - 0.4 pounds of apples are needed
then to make 20 apple pies - 0.4 x 20 = 8 pounds of apples are needed
therefore 8 pounds of apples are required
A bar is used to show subtraction in the case 4-3 (four take away three)
Answer:
What kind of mathematics is this?
Answer:
1. y=3/2x + 12 2. y= 1/4x + 8
Step-by-step explanation:
Use the slope formula to get the slope for each line. Then plug either of the x and y coordinates into the formula y= mx + b and also plug in the slope that you just found and solve for b.
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.
