The first option is incorrect because the function is negative between -4 and -2.

The third option is incorrect because the function is negative between -3 and -2.

The forth option is incorrect because the function is positive for x < -6.

What’s the answer to this

Setler [38]

Answer:

The answere is (9,3)

Step-by-step explanation:

first equation

x - 2y = 3

9 - 2(3) = 3

9-6 = 3

3 = 3

second equations

2x - 3y = 9

2(9) - 3(3) = 9

18 - 9 =9

9 = 9

x - 2y = 3

x = 2y + 3

2(2y + 3 ) - 3y = 9

4y +6 - 3y = 9

y + 6 = 9

y =3

x - 2(3) = 3

x - 6 =3

x = 9

so (9,3)

Consider H0: μ = 45 versus H1: μ < 45. A random sample of 25 observations produced a sample mean of 41.8. Using α = .025 and

a_sh-v [17]

Given
$H0: \ \mu=45 \\ \\ H1: \ \mu\ \textless \ 45$
This is a one-tailed test.

$z= \frac{41.8-45}{6/ \sqrt{25} } = \frac{-3.2}{6/5} = \frac{-3.2}{1.2} =-2.6667$

$P(z\ \textless \ -2.6667)=0.00383$

Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.
