Answer:

72°

Explanation:

Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.

Using the rule of Alternate Exterior Angle theorem, x would equal to 72°.

Answer: 72

Now that we are told that J and K are parallel, we know that there can be a transversal line (m). You can see that m goes 72 degrees.

So, the answer is 72. Best of Regards!

The contents of a sample of 26 cans of apple juice showed a standard deviation of 0.06 ounces. We are interested in testing to d

NikAS [45]

Answer:

Option b. should not be rejected

Step-by-step explanation:

We are given that the contents of a sample of 26 cans of apple juice showed a standard deviation of 0.06 ounces.

We have to test whether the variance of the population is significantly more than 0.003, i.e.;

Null Hypothesis, $H_0$ : $\sigma$ = $\sqrt{0.003}$

Alternate Hypothesis, $H_1$ : $\sigma > \sqrt{0.003}$

The test statistics used here for testing variance is;

T.S. = $\frac{(n-1)s^{2} }{\sigma^{2} }$ ~ $\chi^{2}__n_-_1$

where, s = sample standard deviation = 0.06

n = sample size = 26 cans

So, Test statistics = $\frac{(26-1)0.06^{2} }{0.003 }$ ~ $\chi^{2}__2_5$

= 30

So, at 5% level of significance chi square table gives critical value of 37.65 at 25 degree of freedom. Since our test statistics is less than the critical so we have insufficient evidence to reject null hypothesis.

Therefore, we conclude that null hypothesis should not be rejected and variance of population is 0.003.

erica makes a banner using 4 sheets of paper. Each paper measures 9 inches by 19 inches. What is the total area of Erica's banne

pickupchik [31]

To find the area of the paper. You must multiply the width and the height, which is 9 and 19. 9 x 19 is 171 And multiply that by 4 171 x 4 = 684 Total area is 684

Somebody please help algebra nation doesn’t help

Elena L [17]

What the question is really asking for is the x-intercept (the point at which the graph crosses the x-axis), which, according to the graph, is 6.
