Answer:

192π unit²

Step-by-step explanation:

Given that :

Radius = 24

Area of circle = πr²

Area = π*24²

Area = 576π in²

The Shaded area is 120°

Entire Circumference = 360°

Hence, shaded area = 120°/ 360° = 1/ 3 of the area

1/3 * 576π in²

= 192π unit²

Answer:

0.8586 = 85.86% probability that she does not have all the red ones.

Step-by-step explanation:

The marbles are grabbed without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

In this question:

Bag has 4 + 4 + 3 + 1 = 12 marbles, which means that [tex]N = 12[/tex]

She grabs eight of them, which means that [tex]n = 8[/tex]

Four are red, which means that [tex]k = 4[/tex]

Probability that she does not have all the red ones.

This is

[tex]P(X < 4) = 1 - P(X = 4)[/tex]

In which

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 4) = h(4,12,8,4) = \frac{C_{4,4}*C_{8,0}}{C_{12,8}} = 0.1414[/tex]

Then

[tex]P(X < 4) = 1 - P(X = 4) = 1 - 0.1414 = 0.8586[/tex]

0.8586 = 85.86% probability that she does not have all the red ones.

Answer:

4

Step-by-step explanation:

- the rule is: (number_of_questions)*(points_per_question)=total_score.

- according to the rule above: 26*(points_per_question)=104, then

points_per_question=104/24=4.

Step-by-step explanation:

Use the following formula:

[tex]A=2\pi rh+2\pi r^{2}[/tex]

Take the value of [tex]\pi[/tex] as 3.14 and add the values in the formula:

[tex]A=2(3.14)(2)(6)+2(3.14)(2)^{2}[/tex]

[tex]A=75.36+25.12[/tex]

Answer:

33

Answer:

30° and 150°

Step-by-step explanation:

We want to find the angles in the range:

0° < θ < 360°

Such that:

4*cos^2(θ) - 2 = 1

The first part is to isolate the variable θ in one side of the equation, let's do that:

4*cos^2(θ) = 1 + 2 = 3

cos^2(θ) = 3/4

cos(θ) = ± √(3/4) = ± (√3)/2

Then we have two possible values of θ, one for:

cos(θ) =  (√3)/2

And another for

cos(θ) = - (√3)/2

For both cases, we can use the inverse cosine function, Acos(x)

that has the property Acos( cos(x) ) = x

Then:

cos(θ) =  (√3)/2

Acos( cos(θ) ) = Acos(  (√3)/2)

θ = Acos(  (√3)/2) = 30°

And for the other case we have:

θ = Acos( - (√3)/2) = 150°

Then the two values of theta are: 30° and 150°

(We can see that both of these values are in the range 0° < θ < 360°)

Answer:

  $60

Step-by-step explanation:

The total she started with is the sum of the amount she spent and the amount remaining:

  $25.80 +$9.25 +$18.85 +$6.10 = $60.00

Ashley brought $60.00 to the mall.

Answer:

The Total money she bring to mall is $ 60.

Step-by-step explanation:

Given that :-

After a shopping trip to the mall. Ashley saw $6.10 in her purse she spent $ 25.80 on a pair of shoes, 59.25 on a necklace, and $18.85 on a belt.

To find :-

How much money did Ashley bring to the mall ?

Solution :-

Total money she bring to the mall = sum of amount she spend and amount remaining.

Total money = $ 25.80 + $ 59.25 + $ 18.85 + $6.10

Hence, The total money she bring to mall is $ 60.00.

Let height of monument = h

Using trigonometric relation :

Tan θ = Opposite / Adjacent

Tan 47 = h / 32

h = tan 47 * 32

h = 34.315 feets

The measure of angle O (m∠O) is 48°. The correct option is the first option- 48°

From the question, we are to determine the measure of angle O

From one of the circle theorems, we have that

The angle at the center is twice the angle at the circumference

∴ m∠O = 2 × m∠R

From the diagram, m∠R = 24°

Then,

m∠O = 2×24°

m∠O = 48°

Hence, the measure of angle O (m∠O) is 48°. The correct option is the first option- 48°

Answer:

4 / x¹⁴y⁸

Step-by-step explanation:

eliminate parenthese by multiplying all exponents inside parentheses by the exponent outside the parentheses:

1/2⁶ ÷ 1/4⁴ = 1/64 ÷ 1/256 which equals 256/64 or 4

x⁻⁶y⁴ ÷ x⁸y¹² = x⁻¹⁴y⁻⁸ = 1/x¹⁴ · 1/y⁸

put it all together to get:

Answer:

A) (-9/7,0), (3/8,0)

Step-by-step explanation:

Zeros of a quadratic function:

x for which y = 0.

In this question:

[tex]y = 6(7x + 9)(8x - 3)[/tex]

It's 0 if one of the factors is 0. 6 is never 0, now about the other to:

[tex]7x + 9 = 0[/tex]

[tex]7x = -9[/tex]

[tex]x = -\frac{9}{7}[/tex]

So (-9/7, 0) is a zero of the quadratic function.

The other is:

[tex]8x - 3 = 0[/tex]

[tex]8x = 3[/tex]

[tex]x = \frac{3}{8}[/tex]

(3/8,0) is the other zero.

Thus, the correct answer is given by option A.

Number 1 is 5y = 50

Number 2 is h = 7

Number 3 is multiplication

Number 4 is addition
