Answer:

$\sf H = -10.8$

________

$\sf Solve$

$\sf Move~terms~not~containing~H~to~the~right.$

$-5.4 + 5.4 = -10.8$

________

<em>now, note that if this was actually subtracting, logically, the answer would be H = 0</em>

<em>however, this is an addition problem, meaning to add a negative and a positive integer to get a negative integer.</em>

Multiply 5.4 x2 and put a negative symbol in front

How do I simplify ((3x^2+12x+12)/(2x^2+x-6))/((4x^2-9)/(3x^3+x^2-10))

Shalnov [3]

$\dfrac{ \frac{3x^2+12x+12}{2x^2+x-6} }{ \frac{4x^2-9 }{3x^3+x^2-10} } =$

$= \dfrac{3(x + 2)^2}{(2x - 3)(x + 2)} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)}{2x - 3} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)(3x^3+x^2-10) }{(2x - 3)^2(2x + 3)}$

Question 1 a

Marizza181 [45]

Answer:

B) A one-sample t-test for population mean would be used.

Step-by-step explanation:

The complete question is shown in the image below.

The marketing executive is interested in comparing the mean number of sales of this year to that of previous year.

The marketing executive already has the value of mean from previous year and uses a sample to calculate the mean and standard deviation of sales for the current year.

Since, data is being collected for one sample only this limits us to chose between one sample test for mean. So now the possible options are one sample t-test for population mean and one sample t-test for population mean.

If we read the statement we can see that we have the value of sample mean and sample standard deviation. Value of population standard deviation is unknown. In cases where value of population standard deviation is not known and sample standard deviation is given, t-test is used.

Therefore, we can conclude that A one-sample t-test for population mean would be used.
