Size - continuous

Screen type - Qualitative

Number of channels - discrete

Step-by-step explanation:

____size ____screen type ____no of channels

The individual being studied are the characteristics of high definition televisions

Size of television is a continuous variable as the inches of televisions aren't finite and may not necessarily be whole numbers.

Screen type is a Qualitative variable also called categorical as it places different Television sets into distinct category based on the nature of the screen material.

Number of channela is discrete as it defines a finite number stations available. Available stations will always be whole numbers without decimals.

Answer:

4. 1/125

.______.

Answer:

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(-8,-6) and T(4, 12)

We have

[tex]M = ( \frac{ - 8 + 4}{2} \: , \: \frac{ - 6 + 12}{2} ) \\ = ( - \frac{4}{2} \: , \: \frac{6}{2} )[/tex]

Problem 1

Answer: x = 9

----------

Explanation:

For now focus on triangle DEF. We need to find the missing angle D.

D+E+F = 180

D+71+42 = 180

D+113 = 180

D = 180-113

D = 67

In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent

Let's see what happens when we force them to be equal

angle EDF = angle GHF

67 = 5x+22

67-22 = 5x

45 = 5x

5x = 45

x = 45/5

x = 9

Answer:

f( x) = x ^2 + 1

The equation  f( x) = x² + 1 makes the table true.

Two or more expressions with an equal sign is called as equation.

The given  table is

x     y

0     1

2     5

5     26

7      50

The table value satisfy with the function f( x) = x² + 1=y

if x=0, then y=f(0)=0² + 1=1

if x=2, then y=f(2)=2² + 1=4+1=5

if x=5, then y=f(5)=5² + 1=25+1=26

if x=7, then y=f(7)=7² + 1=49+1=50

Therefore f(x)=x² + 1 is the equation of table.

Answer:

f(x) = - [tex]\frac{1}{2}[/tex] x

Step-by-step explanation:

The standard form for a linear function is

f(x) = ax + b

Using the given values f(- 4) = 2 and f(6) = 3 , then

- 4a + b = 2 → (1)

6a + b = - 3 → (2)

Subtract (2) from (1) term by term to eliminate b

- 10a = 5 ( divide both sides by - 10 )

a = - [tex]\frac{1}{2}[/tex]

Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b

Substituting into (1)

2 + b = 2 ( subtract 2 from both sides )

b = 0

Thus the linear function is

f(x) = - [tex]\frac{1}{2}[/tex] x

The linear function is f(x) = -0.5x

For f(-4) = 2

x₁ = -4, y₁ = 2

For f(6) = -3

x₂ = 6, y₂ = -3

The slope(m) is found using the formula

m = (y₂ - y₁)/(x₂ - x₁)

m = (-3-2)/(6-(-4))

m = -5/10

m = -0.5

Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:

y - y₁ = m(x - x₁)

y - 2 = -0.5(x - (-4))

y - 2 = -0.5(x + 4)

y - 2 = -0.5x - 2

y = -0.5x - 2 + 2

y = -0.5x

Therefore, the linear function is f(x) = -0.5x

Answer:

∠ BAF = 140°

Step-by-step explanation:

Since BD is a tangent to the circle at point B , then

∠ ABD = 90°

The exterior angle of a circle is equal to the sum of the 2 opposite interior angles.

∠ BAF is an exterior angle, thus

∠ BAF = ∠ ABD + ∠ BDA = 90° + 50° = 140°

Answer:

k=45

Step-by-step explanation:

Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have  [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

Answer:

kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation

Step-by-step explanation:

8.912 times 10 superscript 5 is written is scientific notation

The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.

From the question, Kailey's expression can be represented as:

8,912,000 = 89.12 * 10^5 in scientific notation

To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9

The number of zero is 6.

So, the scientific notation of the number is

8,912,000 = 8.912 * 10^6

This means that Kailey's expression is not correct

Hence, the true statement is (d)

Explanation:

Angle JEK is composed of two rays EJ and EK

Ray EJ lands on 140 degrees while EK is on 180 degrees

Subtract the two values: 180-140 = 40

So angle JEK is 40 degrees. Since this is less than 90, the angle is acute.
