Multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a given linear equation.

After solving the linear equation we get:

$\rm \dfrac{25}{9}x = 25$

To make the coefficient of the variable 1

Multiply by 9/25 on both sides.

$\rm \dfrac{9}{25}\times\dfrac{25}{9}x = 25\times \dfrac{9}{25}$

x = 9

Thus, multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.

I need to know number 6SP please I need to find the mean

vodka [1.7K]

The mean absolute deviation is given by the next formula:

$\text{MAD}=\frac{1}{n}\sum ^{\square}_i|x_i-\bar{x}|$

Where n is the number of points in the data set and x with a bar on top is the mean.

In our case,

$\bar{x}=\frac{1}{25}(5\cdot1+5\cdot2+4\cdot3+4\cdot4+6\cdot5+6\cdot1)=\frac{79}{25}$

and n=25.

Then,

$\text{MAD}=\frac{1}{25}(5|1-\frac{79}{25}|+5|2-\frac{79}{25}|+4|3-\frac{79}{25}|+4|4-\frac{79}{25}|+6|5-\frac{79}{25}|+|6-\frac{79}{25}|)$

Finally,

$\text{MAD}=\frac{862}{625}\approx1.4$

The answer is 1.4 once rounded.

The 87 degree angle is a supplementary angle, and the corresponding angle (BAC) is 93 degrees. I know this because two supplementary angles add up to 180 degrees. 180 degrees - 87 degrees = 93 degrees. :D

Answer:

.55

Step-by-step explanation:

You want to shorten the decimal to just to two after the decimal point. If so for example, .443 would be shortened to .44, but if the third number is 5 and up, you would take the second number after the decimal point and add 1. For example,

.446 would round up to .44, which is why .5524 would round to .55

The length of a chord is equal to its distance to the center of the circle. A second chord in the same circle is twice as long a

Rama09 [41]

Answer:

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.

Step-by-step explanation:

The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

$r^2=OC^2+AC^2,\\ \\r^2=(2x)^2+x^2=5x^2,\\ \\r=\sqrt{5}x.$

The length of the arc ED is 4x.

Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

$OF^2=OE^2-EF^2,\\ \\OF^2=5x^2-(2x)^2=x^2,\\ \\OF=x.$

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
