The equation of the linear regression line represents the relationship between the number of years since 2000, x, and the averag

e cost of tuition at a four-year college, y. What does the slope of the line represent? yˆ = 938x + 12,765
For every year since 2000, the cost of tuition increased by $12,765
For every year since 2000, the cost of tuition decreased by $938
For every year since 2000, the cost of tuition increased by $938
The cost of tuition in the year 2000 was $938

The regression equation is in the form y = mx+b where m = 938 is the slope

The slope of 938 means that each year the tuition is increasing by roughly $938.

The answer is choice C.

jekas [21]

To find the average, combine all the numbers together and divide by the amount there is.

-7 + 2 - 9 - 4 - 7 = -25

-25/5 = -5

-5 is your average temperature

hope this helps

No links or files please
Cerrena [4.2K]

The guy who links files is pretty annoying amiright...

Divide 18/35 by 3/5 to get your answer. You can also multiply 3/5 by 35/18.

5 goes into 35 7 times, so cross out the 5 and 35 and put 1 and 7. 3 goes into 18 6 times, so cross out the 3 and 18 and put 1 and 6.

Now you have 1/1 times 7/6. Your answer is 7/6.

The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. F
musickatia [10]

Answer:

P(X \geq 1)=1-P(X

P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801

And replacing we got:

P(X \geq 1) = 1-0.9801 = 0.0199

Step-by-step explanation:

Let X the random variable of interest "number of craked eggs", on this case we now that:

X \sim Binom(n=2, p=0.01)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

And we want to find this probability:

P(x \geq 1)=1-P(X

And we can find the probability:

P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801

And replacing we got:

P(X \geq 1) = 1-0.9801 = 0.0199
