please answer the following and give a good explanation

Answer:

Function: A, C, F, H,I

NOT: B,D,E,G

Step-by-step explanation:

To be a function every x is only allowed to pair up with one y. If there's no repeated x's, then its a function. If x repeats, it has to have the same y as the first time it showed up. If a vertical line (up and down) touches a graph in more than one place, its NOT a function. Any y can partner up with however many x's it wants to, doesn't matter, its still a function. But to be a function ONLY ONE y for each x. Life's not fair.

Answer:

False

Step-by-step explanation:

the highest degree of the equation is 3, meaning that the equation is NOT linear.

The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

John is playing a game of darts. In this game of dart,

The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.

Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,

[tex]P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}[/tex]

Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

Answer:

84 cm

Step-by-step explanation:

Equilateral triangle have sides that measure the same

so

3x-2 = 18+x

Subtract x from each side

3x-2-x =18+x-x

2x-2 = 18

Add 2 to each side

2x-2+2 = 18+2

2x= 20

Divide by 2

2x/2 = 20/2

x = 10

The side measures18+x = 18+10 = 28

The perimeter is 3 times the length of one side

3*28 = 84

Answer:

Two shades will be prepared.

Step-by-step explanation:

Ms Baca told the students that when two colors yellow and blue are mixed in the same ratio same shade is prepares.

From the table attached,

If A is a mixture of 1 part yellow and 2 parts of blue color,

Ratio of the colors = 1 : 2

If B is a mixture of 2 parts yellow and 3 parts of blue color,

Ratio of the colors = 2 : 3

If C is the mixture of 3 parts yellow and 6 parts of blue color,

Ratio of the colors = 3 : 6 = 1 : 2

If D is a mixture of 4 parts yellow and 6 parts of blue color,

Ratio of the colors = 4 : 6 = 2 : 3

If E is a mixture of 6 parts yellow and 9 parts of blue color,

Ratio of the colors = 6 : 9 = 2 : 3

Therefore, mixtures A, C will create the same shade while mixtures B, D, E will be of same shade but different from A and C.

Two shades of the paints will be made by the students.

Answer:

Step-by-step explanation:

Normally Noah is expected to pay an amount without a discount.

let this amount be x

so the amount paid monthly after the discount is removed is (x-5)

Noah paid this amount for 8 months

(x-5)*8=248

solving for x we will get the amount that Noah is expected to be charged when he stopped using the autoplay

(x-5)*8=248

8x-40=248

8x=248+40

8x=288

divide both sides by 8 we have

x=288/8

x=$36

Answer:

Step-by-step explanation:

The remainder on dividing f(x) by (x + h) is f(- h)

Given

f(x) = - x³ - x² + 3 , then

f(- 3) = - (- 3)³ - (- 3)² + 3 = - (- 27) - (9) + 3 = 27 - 9 + 3 = 21 ← remainder

Answer:

30.854%

Step-by-step explanation:

First, we find the z-score corresponding to the value given

z-score = (x - mean)/SD

Z-score = (36-35)/2 = 1/2 = 0.5

we find the Probability of (x > 0.5)

we use the standard normal distribution table for this

P( x > 0.5) = 0.30854

This has a percentage 30.854%

Answer:

r = 55.2 cm

Step-by-step explanation:

the arc length is calculated as

arc = circumference × fraction of circle

     = 2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] ( r is the radius )

given arc = 63.48π , then

2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] = 63.48π ( cancel 2π on numerator/ denominator )

r × [tex]\frac{23}{20}[/tex] π = 63.48π ( divide both sides by π )

[tex]\frac{23r}{20}[/tex] = 63.48 ( multiply both sides by 20 to clear the fraction )

23r = 1269.6 ( divide both sides by 23 )

r = 55.2 cm

[tex]r_{2}[/tex]Answer:

D) 96%

Step-by-step explanation:

let the circumference of circle be C = 2π[tex]r_{1}[/tex] and   [tex]r_{1}[/tex] =   [tex]d_{1}[/tex]/2

Initial radius (radius before increment) = [tex]r_{1}[/tex]

initial diameter (diameter before increment) = [tex]d_{1}[/tex]

Increasing the circumference of a circle other factors are constant except the radius which can be used to find the diameter hence increasing the circumference of a circle is equivalent to increasing the diameter

area of the circle before increment [tex]A_{1}[/tex] = π[tex]r_{1}[/tex]²

[tex]A_{1}[/tex] = π × ([tex]d_{1}[/tex]/2)²

[tex]A_{1}[/tex] = π[tex]d_{1}[/tex]²/4

Increment of circumference results to increment of only the diameter

diameter after increment by 40%, [tex]d_{2}[/tex] = 1.4[tex]d_{1}[/tex]

1.4 represents increment by 40%

radius after increment [tex]r_{2}[/tex]  =  [tex]d_{2}[/tex]/2 = 1.4[tex]d_{1}[/tex]/2 = 0.7[tex]d_{1}[/tex]

area after increment, [tex]A_{2}[/tex] = π[tex]r^{2} _{2}[/tex]

[tex]A_{2}[/tex] = π(0.7[tex]d_{1}[/tex])²

[tex]A_{2}[/tex] = π × 0.49[tex]d_{1}[/tex]²

Change in area =  [tex]A_{2}[/tex] - [tex]A_{1}[/tex]  

[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π ×  0.49[tex]d_{1}[/tex]² - π [tex]d_{1}[/tex]²/4

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]  = π [tex]d_{1}[/tex]²(0.49 - ¼)

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]  = π [tex]d_{1}[/tex]²(0.49 - 0.25)

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]   = 0.24 π[tex]d_{1}[/tex]²

Percentage increment = ([tex]A_{2}[/tex] - [tex]A_{1}[/tex]/ [tex]A_{1}[/tex]) × 100

= ((0.24 π[tex]d_{1}[/tex]²)/(π[tex]d_{1}[/tex]²/4)) × 100

= (0.24 × 4 ) × 100

= 0.96 × 100

= 96 %

Answer:

x = 6

Step-by-step explanation:

The 2 angles given are same- side interior angles and are supplementary, thus

4x + 29 + 12x + 55 = 180, that is

16x + 84 = 180 ( subtract 84 from both sides )

16x = 96 ( divide both sides by 16 )

x = 6

x / 9.8 = 6.4 / 11.2

x = 6.4 / 11.2 * 9.8 = 5.6

Answer:

0.7

Step-by-step explanation:

In order to determine if the tenth place is rounded up one number or stay the same, you have to look at the hundredths place. In this scenario it's the 2.

0.728416

If the hundredths place is 5 or greater, you round up in the tenth place. If the hundredths place is 4 or less you keep the same number in the tenth place.
