Answer:
b. you sold 17
c. your friend sold 25
Step-by-step explanation:
you=y your friend=x
y=x-8
42=x +y
42=x+(x-8)
42=x+x-8
42=2x-8
50=2x
25=x
Use x to solve for y...
y=25-8
y=17
Answer:
y = 5/7x + 5
Step-by-step explanation:
If you replace the x and y in the equation with points x and y of point (35, 30) and change the 10 to b you can solve for b which is the what changes from the original equation to this one.
30 = 5/7(35) + b
30 = 25 + b
5 = b
Since the equations are parallel they have the same slope.
This is the equation for a parallel line that passes through point (35, 30):
y = 5/7x + 5

how do I do another question
Imagine (or draw) a standard normal curve. Draw a vertical line through the center of this curve, and mark it 3.25 inches. This is the mean diameter. Next, draw vertical lines to represent these sums: 3.25 plus .25, or 3.50 inches; 3.25 less .25, or 3.00 inches, and 3.25 less .50 inches, or 2.75 inches.
Note that 2.75 inches is 2 standard deviations below the mean: That's 2.75 inches less twice 0.25 inches, or 2.75 = 3.25 inches less 2(0.25) inches.
onions with diameters less than 2.75 are rejected; onions with diameters greater than 2.75 inches are accepted.
Find the area to the LEFT of 2.75 inches. In other words, find the area to the left of 2 standard deviations below the mean.
I would use the Empirical Rule here: "68% of data is within 1 standard dev. of the mean; 95% is within 2 standard dev. of the mean.
This tells us that the area to the left of 2.75 inches or -2 standard deviations is 0.025 (half of 0.050). Subtract this from 1.000; you'll get 0.975. This means that 97.5% of the onions will prove to be acceptable, whereas 2.5% will be rejected because they are less than 2.75 inches in diameter.
You could also use a table of z-scores to do this: Determine from the table the area under the std. normal curve to the left of -2 std. dev. Again, this comes out to 0.025, meaning that the area to the right of -2 std. dev is 0.975.
Answer:
5/6 of a pound
Step-by-step explanation:
When you multiply 2/3 by 2 it will equal 4/6 making it smaller then 5/6. and divide the fraction and you will see which is smaller.
