WILL GAVE BRAINLIST!! Use the zero product proper to find the solutions to the equation x^2-x-6=0

Starting with 54 and 36, replace the 54 with the greatest common divisor of 54 and 36, obtaining a1, and then replace 36 with th

nalin [4]

Answer:

1 time

Step-by-step explanation:

Given numbers are 54 and 36.

The greatest common divisor of 54 and 36 = 18

So, $a_1 = 18$ .

The least common multiple of 54 and 36 = 108

So, $b_1 = 108$ .

As 54 is replaced by $a_1$ and 36 is replaced by $b_1$ , so after applying the given procedure, the new number is

$(a_1, b_1)=(18, 108)\cdots(i)$

Now, apply the same procedure, to get $a_2$ and $b_2$ .

The greatest common divisor of 18 and 108 = 18

So, $a_2 = 18$ .

The least common multiple of 18 and 108 = 108

So, $b_2 = 108$ .

As $a_1$ is replaced by $a_2$ and $b_1$ is replaced by $b_2$ , so after applying the given procedure, the new number is

$(a_2, b_2)=(18, 108)$ which is the same as in equation (i)

Hence, after applying the procedure 1 time after $(a_1, b_1)$ , the obtained number $(a_2, b_2)$ is the same as $(a_1,b_1)$ .

Does anyone know the answer to this ? I need help , missing angles .

kenny6666 [7]

A straight line is 180°. See the obtuse angle with the "155°"? There is straight line that starts at the "8)" and goes to the "?". Therefor, that 155° you see can be subtracted from 180. 180-155=25, which means the very acute angle in the triangle is 25°. The three angles in a triangle have to equal 180, and you already have 60 and 25. 60+25 is 85. 180-85 is 95. This means that the bottom right angle within the triangle is 95. Well, if you know angle rules, then you'll know that angle "?" is also 95, because it is perpendicular to the bottom right angle within the triangle. :) Hoped this helped! Sorry I took so long to write it... I had to go to the store before I could finish xD

The city of Raleigh has 11700 registered voters. There are two candidates for city council in an upcoming election: Brown and Fe

Vesnalui [34]

Answer:

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.308.

The expected numbers of voters who would vote for Brown is 3604.

Step-by-step explanation:

The sample statistic is a numerical quantity used to represent a characteristic of a sample. For example, sample mean is a sample statistic representing the average of the sample. Or, sample proportion is a sample statistic representing the proportion of a particular variable in the sample. Or sample variance is a sample statistic representing the variance of the sample.

The sample statistic can be used to estimate the population parameter.

They are known as the point estimate of the parameter.

The sample proportion of a variable X is given by:

$\hat p=\frac{X}{n}$

It is provided that of the n = 250 registered voters selected, the number of voters who said they would vote for Brown is X = 77.

Compute the sample statistic for the proportion of voters surveyed who said they'd vote for Brown as follows:

$\hat p=\frac{X}{n}$

$=\frac{77}{250}\\$

$=0.308$

Thus, the sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.308.

Compute the expected number of people of the 11700 registered voters who would vote for Brown as follows:

$E(X)=N\times \hat p$

$=11700\times 0.308\\=3603.6\\\approx 3604$

Thus, the expected numbers of voters who would vote for Brown is 3604.
