Answer:
Y-intercept of the table = -3 and y-intercept of the graph is = -1.
Intercept of the graph is greater than the intercept of the table.
Step-by-step explanation:
Part (a).
To find the intercept of the table we have to choose two points.
Let 
and 
Using point intercept form we will calculate the slope(m).
So,
⇒ 
Plugging the values.
⇒ 
Using slope-intercept form we can calculate the y-intercept.
Slope intercept form 
Y-intercept = 
Then, 
Plugging the values of in slope intercept form.
We have,
Y-intercept of the values given in the table = -3.
Part (b).
Y-intercept of the graph can be calculated by following the above procedure or simply just by looking onto it.
As the graph is passing through y = -1,so y-intercept of the graph = -1.
Y-intercept of the graph is greater than the y-intercept of the table values.
In the test that Professor Ivy gives, the score has Mean of 74 with a standard deviation of 8. I can't solve no.3 because you didn't upload curve
<span>
There is a rule called "68-95-99.7" rule in normal distribution statistic. These 3 numbers represent the percentage of data that are within 1-3 z score from the mean respectively.

4. The middle 68% of the class would score between what two values (what range of scores)?<span>
Data of middle 68% will be 34% above the mean and 34% below the mean. If you see the Z-score table, </span>34% above the mean(50%+34%=84%) that has 0.84 value would be Z=1. The same with 34% below the mean, Z=-1.<span>
Then, the data range would be:
range= score </span>mean <span> +/- (Z-score * standard deviation)
range= 74 +/- (1*8)
</span>range= 74 +/- 8= 66-82
<span>
5. 99.7% of the students would have test scores between what two values (what range of scores)?
</span>Data of middle 99.7% will be 49.85% above the mean and 49.85% below the mean. If you see the Z-score table, 49.85% above the mean(50%+49.85% =99.85%) that has 0.985 value would be around Z=3. The same with 49.85% below the mean, Z=-3.
range= score mean +/- (Z-score * standard deviation)
range= 74 +/- (3*8)
range= 74 +/- 24= 50-98
<span>
6. Write a sentence using the 99.7% range.
The data range of 99.7% could be interpreted these ways:
Around 99.7% of the student will have a score between 50-98.
If you pick a random student score, there is 99.7% that the score is between 50-98.

Arithmetic increases or decreases by same value
geometric increases by a factor
1024 to 64 is decrease of like 900 or something
from 64 to 4 is 60
60=900 is false
so geometric
maybe
see the factor
1024/64=16
64/4=16
4/(1/4)=16
common factor is 1/4
it is geometric
