G(x)=10 because they g goes into c
Given:
The table of values.
To find:
The equation in slope intercept form.
Solution:
From the given table it is clear that the line passes through the points (5,17), (8,41) and (12,73).
Consider any two points from the table, i.e., (5,17) and (8,41). So, the equation of line is
Therefore, the equation of line in slope intercept form is .
First: solve the expressions
(a) 50% of 20= (.50*20)=10
(b) 30% of 90= (.30*90)=27
(c) 25% of 80= (.25*80)= 20
Next: use substitution
(a) 2(10)=(27) (this is not true)
(b) (27)-(10)=(20) (this is not true)
(c) (10)+(20)=(27) (this is not true)
(d) 2(10)=(20) (this is true)
Your answer is D. Hope this helps :)
Answer:
it's b
3x+(-4)=x+2
Step-by-step explanation: i just took the test.
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.
