Answer:
2 7/16
Step-by-step explanation:
multiply both top and bottom of 2 3/4 to make it 12/16 then subtract from there.
-----> A<span>ny number at all with a 0 exponent is 1; anything with a -ve exponent means "1 over" i.e. 5^-1 means 1/5, 23^-4 means 1/23^4 etc.
</span>----->A number to the power of zero is always 1
<span>A number to the power of a negative number such as 2^-4 is always the reciprocal to the power of 4 so 2^-4 is in fact (1/2) ^4 = 1/2^4 </span>
<span>3^-3/4 is (1/3)^3/4 </span>
<span>(4/9)^-3/5 is (9/4)^3/5
</span>
--->Any number with a zero exponent is equal to 1. A number n to the -x is equal to 1/(n^x)<span>
To simplify a negative exponent expression , I attached an example it is easier that way :)
Hope that helps.xoxo

Answer:
The p-value would be 0.0939
Step-by-step explanation:
We can set a standard t-test for the Null Hypothesis that 
The test statistic then takes the form

with this value we then can calculate the probability that is left to the right of this value
. From theory we know that t follows a standard normal distribution. Then
which is smaller than the p-value set by Breyers of 0.10
Answer:
No
Step-by-step explanation:
A function has 1 y-value for each x-value, but in this situation, the x-value of 1 has both a y-value of 2 and 19 making it not a function.
