Answer: z= -1.636
Step-by-step explanation:
When population standard deviation is known, then the test statistic is given by :-
, where 
= sample mean, 
= population mean, n=sample size , 
= standard deviation
As per given,
Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636
We can conclude that the equation 36x + 9 equals -1/4.

What exactly is an equation?</h3>
- An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
- 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.
So,
- 36x + 9
- 36x + 9 = 0
- 36x = -9
- x = -9/36
- x = -1/4
Therefore, we can conclude that the equation 36x + 9 equals -1/4.

Answer:
I think you mean: x^2 + 3x - 10, then
x^2 + 3x - 10
= x^2 + 5x - 2x - 10
=x(x + 5) - 2(x + 5)
=(x - 2)(x + 5)
