Answer:

arc QS = 104°

Step-by-step explanation:

arc QTS = 2(128) = 256

arc QS = 360 - 256 = 104°

The measure of arc length QS is 104.

We have,

An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.

From the definition,

Inscribed angle = 1/2 x intercepted arc

Now,

128 = 1/2 x QTS

QTS = 256

Now,

QTS + QS = 360

256 + QS = 360

QS = 360 - 256

QS = 104

Thus,

The measure of QS is 104.

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0

to find=x

angle dgc=angle agb(by vertical opposite angle)

ege is a straight line.

angle age+angle agb+angle bgf=180°[straight line measure 180°]

Answer:

16

Step-by-step explanation:

You could solve it two ways:

Cross multiply:

x times 35 = 35x

40 times 14 = 560

35x divided by 35 = x

560 divided by 35 = 16

x = 16

Or:

35 divided by 14 = 2.5

40 divided by 2.5 = 16

x = 16

Step-by-step explanation:

Fluid Ounces would be likely to use to measure the capacity of a mug.

The unit to measure the volume of a mug is required.

The best suitable unit is fluid ounces.

Let us convert each unit to liters which will help us compare the units.

[tex]1\ \text{teaspoon}=0.00493\ \text{l}[/tex]

[tex]1\ \text{quart}=0.95\ \text{l}[/tex]

[tex]1\ \text{fluid ounce}=0.0296\ \text{l}[/tex]

A teaspoon is to small to measure a mug's volume, while a quart is too large.

So, the best suitable unit is fluid ounces.

Given:

The data values are:

22, 14, 24, 20, 36, 28, 43, 35

To find:

The mean absolute deviation of the given numbers.

Solution:

We have,

22, 14, 24, 20, 36, 28, 43, 35

The measure of the given numbers is:

[tex]\overline{x}=\dfrac{\sum_{i=1}^{n} x_i}{n}[/tex]

Where, [tex]x_i[/tex] represents the observations and n is the number of observation.

So, the mean value of the given data set is:

[tex]\overline{x}=\dfrac{22+14+24+20+36+28+43+35}{8}[/tex]

[tex]\overline{x}=\dfrac{222}{8}[/tex]

[tex]\overline{x}=27.75[/tex]

The formula for is mean absolute deviation is:

[tex]M.A.D.=\dfrac{1}{n}\sum_{i=1}^{n}|x_i-\overline{x}|[/tex]

The mean absolute deviation of the given numbers is:

[tex]M.A.D.=\dfrac{1}{8}[|22-27.75|+|14-27.75|+|24-27.75|+|20-27.75|+|36-27.75|+|28-27.75|+|43-27.75|+|35-27.75|][/tex]

[tex]M.A.D.=\dfrac{1}{8}[5.75+13.75+3.75+7.75+8.25+0.25+15.25+7.25][/tex]

[tex]M.A.D.=\dfrac{1}{8}[62][/tex]

[tex]M.A.D.=7.75[/tex]

Therefore, the mean absolute deviation of the given numbers is 7.75.
