An experiment consists of randomly selecting a marble from a bag, not replacing it, and then selecting another marble. The bag contains 3 yellow marbles and 2 white marbles. What is the probability of selecting a white marble and then a yellow marble?

Answer

it is 0.5

Step-by-step explanation:

Answer:

x=8

y=24

Step-by-step explanation:

3x=y

x=y-16

Substitute y for 3x

x=3x-16

Add 16 to each side

x+16=3x

Subtract x

16=2x

Divide each side by 2

8=x

y=3x=3×8=24

y=24

Here we have been given with two equations and we have to calculate the values of x and y. So we would be using substitution method for it.

Here we can clearly see that value of y is 3x. So we would substitute it in Equation No 2.

>> x = y - 16

>> x = 3x - 16

>> x - 3x = -16

>> -2x = -16

>> 2x = 16

>> x = 16 / 2

>> x = 8

★ Finding out value of y:-

>> y = 3x

>> y = 3 (8)

>> y = 3 × 8

>> y = 24 [tex] \: [/tex]

Answer:

  ∠SAP = 85°

Step-by-step explanation:

The whole is the sum of the parts.

  ∠SAX = ∠SAP + ∠PAX

  142° = ∠SAP + 57° . . . . . . . use the given values in the equation

  ∠SAP = 142° -57° . . . . . . . . subtract 57° from both sides

  ∠SAP = 85°

Answer:

x = 15

Step-by-step explanation:

we know that the total degree inside of a triangle made up of 180°

6x + 4x + 2x = 180

12x = 180

x = 15

To find each angle we multiple 4x , 6x, 2x by 15

4(15) = 60°

6(15) = 90°

2(15) = 30°

Answer:

soln,

2x+6x+4x=180°( being s of the angle of triangle is 180°)

12x=180°

X= 180°/12

X= 15

again,

2x=2×15. 6x= 6×15. 4x=4×15

2x=30. 6x=90. 4x=60

Answer:

250 hamburgers

Step-by-step explanation:

so if there were 50 less cheeseburgers then I would take 50 away from 450 and I would get 400. And then I divided it by 2. And so 200+50 = 250 so 250 hamburgers and 200 cheeseburgers. I hope this helps and I'm not good at explaining. :)

Answer:

csc θ

Step-by-step explanation:

cot θ sec θ can be substituted by reducing the expression into equivalent parts.

cot θ = (cos θ)/(sin θ)

sec θ = 1/(cos θ)

Reduce these two values to get 1/(sin θ)

This expression can then be changed to csc θ, as it is also equivalent.

The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ cot θ × sec θ

We know that cot θ = cos θ / sin θ and sec θ = 1 / cos θ, then we have

⇒ cot θ × sec θ

⇒ cos θ / sin θ × 1 / cos θ

⇒ 1 / sin θ

We know that 1 / sin θ = cos θ

⇒ 1 / sin θ

⇒ cosec θ

The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.

Answer:

1) Zero based on (-16·t - 2) is t = -1/8 second

2) Zero based on (t - 1) is t = 1 second

Step-by-step explanation:

The given functions representing the height of the beach ball the child throws as a function of time are;

y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2

We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero

In the function of the question, we have;

y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2

The above equation can be written as follows;

y = (-16·t - 2) × (t - 1)

Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0

1) The zero based on (-16·t - 2) = 0, is given as follows;

(-16·t - 2) = 0

∴ t = 2/(-16) = -1/8

t = -1/8 second

The zero based on (-16·t - 2) is t = -1/8 second

2) The zero based on (t - 1) = 0, is given as follows;

(t - 1) = 0

∴ t = 1 second

The zero based on (t - 1) is t = 1 second

Answer:

rises to the left and rises to the right

Step-by-step explanation:

The end behavior of the graph of f(x) = 3x⁶ + 30x⁵ + 75x⁴ is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The degree of the polynomial function is 6, which is even, and the leading coefficient is positive, so the end behavior of the graph is as follows:

As x approaches negative infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) approaches positive infinity.

As x approaches positive infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) also approaches positive infinity.

Therefore, the end behavior of the graph of f(x) is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

Answer:

m<T = 20°

Step-by-step explanation:

m<R = 140°

m<S = 100°

The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:

m<S = m<U = 100°

Sum of all interior angles of a quadrilateral = 360°

Therefore:

m<T = 360° - (m<S + m<U + m<R)

m<T = 360° - (100° + 100° + 140°) (substitution)

m<T = 20°
