Second question: What is the probability of first selecting a red marble, then selecting a yellow marble? Third question: What is the probability of first selecting a blue or yellow marble, replacing the marble, then selecting a red or blue marble?

Answer:

12x - 29 + 4x + 1 = 180

Step-by-step explanation:

(12x - 29) and (4x + 1) are same- side interior angles and sum to 180° , then

12x - 29 + 4x + 1 = 180 ← is the equation to solve for x

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Step-by-step explanation:

i think this is right

By using the relative frequency, we can expect to not roll a "6" in 11 rolls.

We know that in a total of 72 rolls, the outcome is "6" 21 times.

Then the relative frequency is:

F = 21/72 = 0.292

Then we can expect that in N rolls, we will get (0.292)*N times a "6".

So the number of times that we will not get a 6, is:

(1 - 0.292)*N

In this case is N = 15, then we get:

(1 - 0.292)*15 = 10.62

Rounding to the next whole number we get 11, this means that we can expect to not roll a "6" in 11 rolls.

Step-by-step explanation:

The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)

Answer:

x = -48

Step-by-step explanation:

-4(7.5x - 8) = -5(6.3x + 8)

-30x + 32 = -31.5x - 40

-30x + 31.5x = -40 - 32

1.5x = -72

x = -72/(1.5)

x = -48

Cost of apple share in 2018 = $43.75

Sale price of apple share= $136.76

1. Her gain is

Gain= Sales price- Cost price

Gain = 136.76-43.75

Gain= $93.01

2. ROI is

ROI= Gain/cost*100

ROI= 93.01/43.75*100

ROI=2.1259*100

Answer:

(A) -9 °F

Step-by-step explanation:

On Sunday, the wind chill temperature reached - 36 °F. On Monday, the wind chill

temperature only reached¼ of Sunday's wind chill temperature. What was the

lowest wind chill temperature on Monday? (A) -9 °F (B) -36¼°F (C) -40 °F (D) -144 °F

Sunday temperature = - 36 °F

Monday temperature = ¼ of Sunday's wind chill temperature

Monday = 1/4 of - 36 °F

= 1/4 * -36 °F

= (1 * -36)/4 °F

= -36/4 °F

= -9 °F

Monday temperature = -9 °F

The correct answer is (A) -9 °F

Answer:

x = 45 and y = 90

Step-by-step explanation:

Let the third angle be z

z = 180 - 135 (Linear Pair)

z = 45

Since its an iscosceles triangle,

<z = <x (angles opposite to equal sides have equal angles)

<x = 45 degree

<z + <x + <y = 180

45 + 45+ <y = 180

90 + <y = 180

<y = 180 - 90

<y = 90

Therefore x = 45 and y = 90

Hope u understood please mark as brainliest

Thank You

Answer:

x= 45°

y= 90°

Step-by-step explanation:

x= angles on a straight line add up to 180°. 180°-135° = x.

y= x+y=135° & x =45°

135°- 45° = y

Answer:

The answer is 13 feet.

Step-by-step explanation:

Assuming that the lengths 5ft and 12ft are the legs of the triangle, use the  Pythagorean Theorem to find the unknown length of the hypotenuse:

a^2 + b^2 = c^2

Now, simply plug in the values of the triangle legs:

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

c = 13

Answer:

13 ft

Step-by-step explanation:

The formula to find the length of the hypotenuse is:

[tex]a^2+b^2=c^2[/tex]

---------------------------------------------------------------------------------------------------------------

So:

25 + 144 = 13

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = - 8 ÷ - 2 = - 32 ÷ - 8 = - 128 ÷ - 32 = 4

This indicates the sequence is geometric with nth term

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = 4 , then explicit formula is

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

( x - 4 )^2 + ( y + 7 )^2 = 53

A functional rule is the relationship between an input or domain and an output or scope.

The given function is as follows:

x: -6, -3, 0, 3, 6

y: 5, -1, -7, -13, -19

A functional rule is the relationship between an input or domain and an output or scope. A relation is a function only if it has a value within each domain value. Functions are written like where is the input value. The general form of the function is:

A formula, rule, or law that defines the relationship between one variable (the independent variable) and another (the dependent variable). Functions are ubiquitous in mathematics and essential in the natural sciences for formulating physical relationships.

Let the given function be y = -2x - 7.

Where, x = -6

substitute the values in the above equation, we get

⇒ y = -2(-6) - 7

⇒ y = 5

Let the value of x = -3

substitute the values in the above equation, we get

⇒ y = -2(-3) - 7

⇒ y = -1

Put, x = 0

substitute the values in the above equation, we get

⇒ y = -2(0) - 7

⇒ y = -7

Put, x = 3

substitute the values in the above equation, we get

⇒ y = -2(3) - 7

⇒ y = -6 - 7 = -13

Put, x = 6

substitute the values in the above equation, we get

⇒ y = -2(6) - 7

⇒ y = -19

The given function is as follows:

x: -6, -3, 0, 3, 6

y: 5, -1, -7, -13, -19
