Originally Dan has X amount of base ball cards.
So the equation would be
(x+6)/2=29
multiply both sides by 2
x+6=58
subtract 6
x=52
Check your work: 52+6=58/2=29
Dividing:- (1.75 * 10^18) / (6.25 * 10^15)
= (1.75 / 6.25) * (10^18 / 10^15)
= 0.28 * 10^3
= 280 Answer
For y to not be a function of x, there needs to be an x-value that is paired with more than one y-value.
In terms of the sets, you need to find a set where the same x-value is used more than once in two (or more) different (x,y) pairs.
This occurs in the third set, where x=6 is used twice.

Step-by-step explanation:
While working at his neighborhood math tutoring center researching the comprehension level of the students Dion investigated that the distribution of the student test scores are normally distributed with a mean of 79.13 and a standard deviation of 6.34. What is the probability that the student scores less than 60.11
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
z = 60.11 - 79.13/6.34
Let the 4 integers be x, x+2 , x+4 , x+6 Then
4x + 12 = 7(x + 6)
4x + 12 = 7x + 42
3x = -30
x = -10
The integers are -10 -8 , -6, and -4 answer
