Find each value or measure. Assume that segments that appear to be tangent are tangent. Find QS

Answers

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.

Which unit would you must likely use to measure the capacity of a mug?
A. Teaspoons
B. Quarts
C. Fluid Ounces ?

Answers

Answer:

c

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.

The list shows the number of minutes that eight students spent on math homework last week. 22, 14, 24, 20, 36, 28, 43, 35What is the mean absolute deviation of the numbers

Answers

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.

7x-4+8x=6x+8 abcdefghijklmnop

Answers

Answer:

x = 4/3

Step-by-step explanation:

7x − 4 + 8x = 6x + 8

Answer:

x=[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].
