Answer:

B.

Step-by-step explanation:

In statement (1), we are given that m∠BAC=m∠BCA

If the two angles are congruent, this means that the sides opposite the angles are also congruent. These sides are AB and BC. Therefore:

AB=BC    |    B. sides opposite equal angles are equal

:Done

*The side opposite a given angle is the side towards which the angle opens up to. For example, ∠BAC opens up towards the side BC, and ∠BCA opens up towards side BA.

Why does the square root of 3 x the square root of 3 = 3?
stealth61 [152]

Answer: the square root of 3 is: (a number) times ITSELF is equal to 3. Therefore, if you multiply that number times that number again, it is equal to 3.

Ex1- sqrt of 4 times the sqrt of 4 —> 2 times 2 which is 4

Ex2- sqrt of 9 times the sqrt of 9 —> 3 times 3 which is 9

What is the standard form equation of the line shown below? Graph of a line going through negative 2, 3 and 1, negative 3
V125BC [204]

Answer:

3. 2x + y = −1

Step-by-step explanation:

To find the equation of the line, we write it first in the slope-intercept form:

y=mx+q

where

m is the slope

q is the y-intercept

From the graph, we see that the line crosses the y-axis at y = -1, so the y-intercept is -1:

q=-1

Now we have to find the slope, by calculating the rate of change of the line through 2 points:

m=\frac{y_2-y_1}{x_2-x_1}

Taking the two points at (-2,3) and (1,-3), we find:

m=\frac{-3-3}{1-(-2)}=\frac{-6}{3}=-2

So the equation of the line is

y=-2x-1

Now we have to re-arrange it in the standard form, so in the form

ax+bx=c

where a, b and c are integer numbers.

To do that, we simply add +2x on both sides of the equation of the line in the slope-intercept form, and we get:

y+2x=-1

So, option 3).

the results of a poll indicate that between 33% and 37% of the population of a town visit the library at least once a year. what
Vera_Pavlovna [14]

The margin of error is ±2%

<h3>What is Margin error?</h3>

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.

Let x be margin of error and y be the percentages of the population.  

So,

y-x =33%

y +x = 37%

Solving above equations

2y= 70

y= 35%

and x= 2%

Hence, the margin of error is ±2%.
