(3x - 1)(3 -x)+x^2 + 19

a)
(3x - 1)(3 -x)+x^2 + 19
=9x - 3x^2 - 3 + x + x^2 + 19
= -2x^2 + 10x + 16

b) evaluate at x = 2

-2x^2 + 10x + 16
= -2 (2^2) + 10(2) + 16
= -8 + 20 + 16
= 28

c)
from part (a)
-2x^2 + 10x + 16

= -2 (x^2 - 5x - 8) (complete factor)

Ann [662]

Answer:

$t=\frac{1.20-1.25}{\frac{0.14}{\sqrt{49}}}=-2.50$

Step-by-step explanation:

Data given and notation

$\bar X=1.20$ represent the sample mean given

$\sigma = 0.14$ represent the population standard deviation

$n=49$ sample size

$\mu_o =1.25$ represent the value that we want to test

t would represent the statistic (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the true mean for the gasoline prices is lower than 1.25, the system of hypothesis would be:

Null hypothesis: $\mu \geq 1.25$

Alternative hypothesis: $\mu < 1.25$

If we analyze the size for the sample is > 30 but we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Calculate the statistic

We can replace in formula (1) the info given like this:

$t=\frac{1.20-1.25}{\frac{0.14}{\sqrt{49}}}=-2.50$
