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:
Step-by-step explanation:
hello :
(2x + 9)(3-z) = 0 means : 2x+9=0 or 3-z=0
x= -9/2 or z=3
Answer: In the figure AB is about 8.4 inches and AC is about 13.05 inches.
Step-by-step explanation: We can use cosine to find the hypotenuse. 
Using a calculator x is about 13.05
Using tangent we can find the length opposite of <C
Using a calculator x would be about 8.4
-5x^3 + 2x^2 + 1
a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.
so in ur problem....there are 2 coefficients..-5 and 2.
** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.
** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.
okay...I am gonna shut up now :)
