Answer:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Step-by-step explanation:

The average absolute deviation, or mean absolute deviation, of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.

A leaky pool loses 2 1/4 inches of water eachday. Jermain and mildred are asking to determine the change in the amount of water

inessss [21]

Answer:

Over 5 days, the pool loses 11 $\frac{1}{4}$ inches of water.

Step-by-step explanation:

Since the leaky pool is losing water at a rate of 2 $\frac{1}{4}$ inches of water each day, than we can find the amount of water the pool has lost over 5 days, by either adding 2 $\frac{1}{4}$ five times, or just multiplying 2 $\frac{1}{4}$ by 5:

2 $\frac{1}{4}$ x $\frac{5}{1} =\frac{9}{4} x\frac{5}{1} =\frac{45}{4} =11\frac{1}{4}$

So, the total amount of water lost over 5 days is 11 $\frac{1}{4}$ inches.

Can someone please help me :)

gavmur [86]

Answer:

<em>90 degree</em>

Step-by-step explanation:

Three points A, B, and C are added and shown in attached picture.

As the property of inscribed angle in circle:

angle BAC = (1/2) x 88 = 44 deg

As the property of complement angle:

angle ABC = 180 - 89 = 91 deg

As the property of sum of three angles in a triangle:

angle ACB + angle ABC + angle BAC = 180 deg

=> angle ACB = 180 - angle ABC - angle BAC = 180 - 44 - 91 = 45 deg

One more time, we use the property of inscribed angle in circle:

x = 2 x angle ACB = 2 x 45 = 90 deg

Hope this helps!

Two forces of 401 newtons and 477 newtons act on a point. The resultant force is 828 newtons. Find the

Ray Of Light [21]

Answer:

The answer is " $39.01^{\circ}$ "

Step-by-step explanation:

$\to R= 828\\\\\to F_1= 401\\\\\to F_2=477\\\\\to \bold{R=\sqrt{F_1^2+F_2^2+2F_1F_2 \cos \theta}}$

$828=\sqrt{401^2+477^2+2 \times 401 \times 477 \cos \theta}\\\\828=\sqrt{160801+227529+382554 \cos \theta}\\\\828=\sqrt{388330+382554 \cos \theta}\\\\$

square the above equation:

$(828)^2=(\sqrt{388330+382554 \cos \theta})^2\\\\$

$685584 =388330+382554 \cos \theta\\\\685584 -388330=382554 \cos \theta\\\\297254=382554 \cos \theta\\\\\cos \theta=\frac{297254}{382554}\\\\\cos \theta=0.777025\\\\\theta= \cos^{-1} 0.777025\\\\\theta= 39.01^{\circ}$

Solve the system of equations using the substitution method.

ANTONII [103]

The solution of system of equations is: x = 1.6 and y = 1.2

Step-by-step explanation:

Given equations are:

$y = 2-\frac{1}{2}x\ \ \ \ Eqn\ 1\\x-3y = -2\ \ \ eqn\ 2$

Putting $y = 2-\frac{1}{2}x$ in equation 2

$x - 3(2-\frac{1}{2}x) = -2\\x - 6 + \frac{3}{2}x = -2\\x +\frac{3}{2}x = -2+6\\\frac{2x+3x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4 * 2\\5x = 8\\x = \frac{8}{5}\\x = 1.6$

Putting x = 1.6 in equation 2

$1.6-3y = -2\\-3y = -2-1.6\\-3y =- 3.6$

Dividing both sides by -3

$\frac{-3y}{-3} = \frac{-3.6}{-3}\\y = 1.2$

Hence,

The solution of system of equations is: x = 1.6 and y = 1.2
