Answer:
1. 1/2, rise/run and since you rise one and run 2 it'll be 1/2
2. 7/0 = undefined automatically, there is no value(undefined) if there is no run
3. rise: 28 - 18 10 5
_______ = _____ = _____ = 5
run: 4 - 2 2 1
4. 1, it rises 1 and runs 1
Answer:
a. The null and alternative hypothesis can be written as:

b. A Type I error is made when a true null hypothesis is rejected. In this case, it would happen if it is concluded that the actual mean outstanding credit card debt of college undergraduate is significantly less than $3173, when in fact it does not.
A Type II error is made when a false null hypothesis is failed to be rejected. In this case, the actual mean outstanding credit card debt of college undergraduate is in fact less than $3173, but the test concludes there is no enough evidence to claim that.
Step-by-step explanation:
We have a prior study of the mean outstanding credit card debt of college undergraduate that states that it was $3173 in 2010.
A researcher believes that this amount has decreased since then.
Then, he has to perform a hypothesis test where the null hypothesis states that the mean is still $3173 and an alternative hypothesis that states that the actual credit card debt is significantly smaller than $3173.
The null and alternative hypothesis can be written as:

Answer:22
Step-by-step explanation: since f(8) so x=8
substitiuting x in 2x+6
f(8)= 2x8+6=22
so f(8)=22
Hope this helps! :)
32.3 is a decimal number in which 3 is the digit at the tenth place.
Mixed number contains a whole number and a fraction part.
32.3 expressed as mixed fraction is
, here 32 is the whole number and
is the fraction part.
is the fraction in the simplest form.
For this reason, 32.3 expressed as a mixed number in the simplest form is
.
1(x-1)/2-1(3-X)/4=2/1. X-1/2-3+x/4=2/1. Find common denominator. 2x-2-3+x=8. 2x+x-5=8 3x=8+5. X=13/3.
