If several points are graphed on a number line, is the point that is the farthest from 0 always the greatest?explain.
balandron [24]

Answer:

No

Step-by-step explanation:

On a number line, the 0 is in the middle. Positive numbers are to the right of the 0 and negative numbers are to the left of the 0. A point farthest from 0 could be on the left side and therefore be really small. Therefore the point farthest from 0 is not always the greatest as it could also be the smallest

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.
ryzh [129]

Answer:

Option (2). 14 m

Step-by-step explanation:

Formula to get the area of a circle 'A' = \pi r^{2}

where r = radius of the circle

Given in the question,

Area of the circle = 153.86 square meters

By putting the values in the formula,

153.86 = πr²

r = \sqrt{\frac{153.86}{\pi } }

r = \sqrt{49}

r = 7 meters

Diameter of circle = 2 × (radius of the circle)

                              = 2 × 7

                              = 14 meters

Therefore, diameter of the circle is 14 meters.

Option (2) is the answer.

creativ13 [48]

When analyzing the multiple regression model, the real estate builder should be concerned with Multicollinearity.

<h3 /><h3>What is Multicollinearity?</h3>

This is a phenomenon in regression analysis where some of the independent variables are correlated. This can present an issue because the correlation leads to less reliable results.

The income in this research is influenced by the education and they both influence family size. There is therefore an issue of multicollinearity here because some variables are correlated.
