Answer:
-13
Step-by-step explanation:
sum of them=-33
the average is -3, thus the middle integer is -3
counting back 5 times, by twos, you get -13
we can confirm this by counting forwards, and getting 10
10=-13=-3
Answer: 37
Step-by-step explanation:Using the Pythagorean Theorem, a ² + b ² =c ², you substitute the values for a and b with 12 and 35. This makes your equation 12 ² +35 ² = c ² . You then add 12 ² with 35 ² and that gives you 37 ² = C ² . You find the square root of both sides which is 37=C, giving you the length of C.
Answer:
Step-by-step explanation:
From the information given, the population is divided into sub groups. Each group would consist of citizens picking a particular choice as the most important problem facing the country. The choices are the different categories. In this case, the null hypothesis would state that the distribution of proportions for all categories is the same in each population. The alternative hypothesis would state that the distributions is different. Therefore, the correct test to use to determine if the distribution of "problem facing this country today" is different between the two different years is
A) Use a chi-square test of homogeneity.
Answer:
(3x - 5)(x + 1)
Step-by-step explanation:
We need to factor 3x² - 2x - 5.
In order to do this, we must look at the factors of 3 and -5:
3 = 1 * 3
-5 = 1 * -5
Somehow, we need to pair up these so that they add to -2. We realize we can do this by multiplying 1 by -5 and adding that to 1 * 3:
1 * -5 + 1 * 3 = -5 + 3 = -2
So, we have (3x - 5)(x + 1).
