Find the number that we can place in the box, so that the resulting quadratic is the square of a binomial.

Mathematics

Arturiano [62]4 years ago

We need a number to complete

(x+c)^2=x^2+2xc+c^2

Since we have

2xc=\dfrac{4}{5}x \iff 2c=\dfrac{4}{5}\iff c=\dfrac{4}{10}=\dfrac{2}{5}

And so the expanded square is

\left( x+\dfrac{2}{5}\right)^2=x^2+\dfrac{4}{5}x+\dfrac{4}{25}

12 10,9,68,12<br> What is the most appropriate measure of center?
valentina_108 [34]

Answer: The most appropriate measure of center is the median.

Step-by-step explanation:

  • The measure of center generally represented by 1) mean 2) median 3) mode.
  • Mean is the best measure to represent the center of the data but when data have outliers it gets affected badly.
  • In that case, we use the Median as the best measure of center.

The given data is 12 10,9,68,12 .

As it can be seen that, the data have extreme value 68 ( called outliers).

In this case, we will use the Median as the best measure of center.

So, the most appropriate measure of center is the median.

Which choice correctly shows rounding to the hundredths place?
Romashka-Z-Leto [24]
Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)

Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up. 

Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.

Choice D is true. The three decimal values are rounded properly to the correct number of decimal places. 

Therefore choice D is the answer

Given that LON is a right angle, find the measure of x.​
sveta [45]

Answer:

x=30\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LOM+m∠MON=m∠LON ----> by angle addition postulate

we have

m∠LOM=2x°

m∠MON=x°

m∠LON=90° ----> is a right angle

substitute the values

2x+x=90

solve for x

3x=90

x=30\°

Let's solve your equation step-by-step.

1  / 3 m= −4

Step 1: Multiply both sides by 3.

3*( 1  / 3 m) = (3) * (−4)

m=−12
