sorry I thought this was funny I have no idea what’s happening
Answer:
Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,
15x + 5y = 45
+ 3x - 5y = 15
The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.

Step-by-step explanation:
Answer:
1. No, because each x value can only have one y value (one-to-one relationship).
2. No, because each x value can only have one y value (one-to-one relationship).
3. Yes, because one member of the domain is assigned to one member of the range.

Answer:
The numerical limits for a D grade is between 57 and 64.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:

D: Scores below the top 80% and above the bottom 7%
Between the 7th and the 100 - 80 = 20th percentile.
7th percentile:
X when Z has a pvalue of 0.07. So X when Z = -1.475.




So 57
20th percentile:
X when Z has a pvalue of 0.2. So X when Z = -0.84.




So 64
The numerical limits for a D grade is between 57 and 64.
This is written in slope intercept form, or y=mx+b, where m is slope and b is y intercept. Just look at the values that represent m and b to find the answer.
Slope: 3/4
Y intercept: -4
