Before we start, find the LCM of 9, 5, and 5, which is 1. The least common multiple for the x is x^3, because it is the smallest exponent. The smallest multiple for y is 0, because the last factor doesn't even have y. For z, it is z^2. So your answer is 1x^3z^2, or just x^3,z^2.

Vilka [71]
To problem wants to compute the probability of the expected value that could be earn if you would draw again another card. So base on the fact that if draw a face card of K,Q,J from a standard deck correctly you will earn 10 point in just one draw, but loose 2 points if you another card, the probability that you would draw correct card in just one draw is 30.77%, so the possible value earn you have 2 points only

andrew-mc [135]

Answer:

z=\frac{7.4-7.6}{\frac{0.9}{\sqrt{130}}}=-2.534    

z_{\alpha}=-2.054

If the calculated value is less than the critical value we reject the null hypothesis.

P value

The p value for this test would be:  

p_v =P(Z  

Since the p value is lower than the significance level given we have enough evidence to reject the null hypothesis at the 25 of significance level given.

Step-by-step explanation:

Information given

\bar X=7.6 represent the sample mean

\sigma=0.9 represent the population deviation

n=130 sample size  

\mu_o =7.4 represent the value that we want to check

\alpha=0.02 represent the significance level for the hypothesis test.  

z would represent the statistic

p_v represent the p value for the test

System of hypothesis  

We want to check if the mean pressure is less then 7.6 pounds/square inch, the system of hypothesis are:  

Null hypothesis:\mu \geq 7.6  

Alternative hypothesis:\mu < 7.6  

The statistic would be:

z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}  (1)  

Replacing the values we got:

z=\frac{7.4-7.6}{\frac{0.9}{\sqrt{130}}}=-2.534    

Critical value

we need to find a critical value who accumulates 0.02 of the area in the left of the normal standard distribution and we got:

z_{\alpha}=-2.054

If the calculated value is less than the critical value we reject the null hypothesis.

P value

The p value for this test would be:  

p_v =P(Z  

Since the p value is lower than the significance level given we have enough evidence to reject the null hypothesis at the 25 of significance level given.

Find the equation is standard form, of the line passing through he points (2,-3) and (4,2)
Simora [160]

The point slope formula:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

(2,\ -3)\to x_1=2,\ y_1=-3\\(4,\ 2)\to x_2=4,\ y_2=2

Substitute:

m=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}=2.5\\\\y-(-3)=2.5(x-2)\\\\y+3=2.5x-5\ \ \ \ |+5\\\\y+8=2.5x\ \ \ \ \ \ |-y\\\\2.5x-y=8\ \ \ \ \ |\cdot2\\\\\boxed{5x-2y=16}
