Answer:

7/39 = 17.94%

Step-by-step explanation:

Town          Students     Relative Frequency

Wilmette   12 boys + 7 girls = 19 19/39 = 48.72%

Glencoe    9 girls + 4 boys = 13 13/39 = 33.33%

Kenilworth  2 boys + 5 girls = 7  7/39 = 17.94%

Total         39 students         39/39 = 100%

Another approach to solve probability is the Relative Frequency. A frequency is the number of times an event occurs. To solve for the relative frequency, it’s the ratio of the frequency of an event to the total outcomes. From the question, it is clear that for each town, it was subdivided into boys and girls but the word students represent the combined number of boys and girls for a particular town. so finding the probability that a student called at random to answer a question is from kenilworth is simply the ratio of students from kenilworth over the total number of students in the class.  

Answer: s, v, w, & x = 13      y = 20        z = 20 + 13√3

Step-by-step explanation:

First, you need to understand the side lengths of each special triangle in the drawing.

A 45°- 45°- 90° triangle has corresponding sides of a - a - a√2

A 30°- 60°- 90° triangle has corresponding sides of b - b√3 - 2b

The hypotenuse of the 45-45-90 triangle is 13√2, so its legs are 13.

So A F = 13 → s = 13 and w = 13

     FB = 13 → x = 13

     EC = 13 → v = 13

Since the x-value of C is 20, then the x-value of E is also 20 → y = 20

ED is opposite of the 60° angle of the 30-60-90 triangle so ED is EC√3.  Since EC = 13, then ED = 13√3.

AE + ED = AD

20 + 13√3 = AD → z = 20 + 13√3

I'm not 100% but i think its A: 3

For this case we have that by definition of power properties:

[tex]\frac {a ^ m} {a ^ n} = a ^ {m-n}[/tex]

We have the following expression:

[tex]\frac {5 ^ 6} {5 ^ 2} = a ^ b[/tex]

It can be rewritten as:

So:

[tex]\frac {5 ^ 6} {5 ^ 2} = 5 ^ {6-2} = 5 ^ {4} = a ^ b[/tex]

So, [tex]b = 4\ and\ a = 5[/tex]

Answer:

884yd²

Step-by-step explanation:

Given in the question a pyramid with a square base

Slant height = 20

length of side of square = 18

To calculate base area

base area of pyramid = l²

                                   = 324 yd²

To calculate the one face of pyramid

area of one face  = 1/2 (height) x (base)

                            = 1/2 (20)(14)

                            = 140

Plug values in the formula

Area of the figure = 324 + 4(140)

                              = 884 yd²

Answer:

Total surface area = 1044 yd²

Step-by-step explanation:

From the figure we can see a square pyramid.

Base = 18 yd

Slant height = 20 yd

To find the Base area

Total surface area = Base area + (4* area of one lateral face)

Base area = Base² = 18² = 324 yd²

To find the lateral surface area

Area of one face = bh/2

b = base = 18 yd

h = Slant height = 20 yd

Area = bh/2 = (18 * 20)/2 = 180 yd²

Lateral surface area = 4 * 180 = 720 yd²

To find the total surface area

Total surface area = 324 + 720 = 1044 yd²

Answer:

a. x = 13

b. x = 7

c. x = 24

d. x = Undefined

Step-by-step explanation:

Since all the bases are the same the power it is raised by is equivalent to the sum's power.

In mathematical terms

.

.

x^a + x^b = x^a+b

So all we have to do is add up the exponents and make them equivalent to each other.

For the last question, it is impossible since the powers added cannot ever be equal to each other.

9+x can never equal 4+x so it is undefined.

Answer:

[tex]x=\frac{\pi}{2}[/tex]  and  [tex]x=\frac{3\pi}{2}[/tex]

Step-by-step explanation:

We need to solve the 2 equations to figure out the x-values (intersecting points).

Note: The identity  [tex]cos^{2}x=\frac{1}{2}+\frac{1}{2}cos(2x)[/tex]

[tex]cos(2x)=cos^{2}(x)-1\\cos(2x)=(\frac{1}{2}+\frac{1}{2}cos(2x))-1\\cos(2x)=\frac{1}{2}cos(2x)-\frac{1}{2}\\\frac{1}{2}cos(2x)=-\frac{1}{2}\\cos(2x)=-1\\2x=cos^{-1}(-1)\\2x=\pi, 3\pi\\x=\frac{\pi}{2}, \frac{3\pi}{2}[/tex]

So they intersect at  [tex]x=\frac{\pi}{2}, \frac{3\pi}{2}[/tex]

Answer:

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Consider the trinomial [tex]3x^2+10x-8.[/tex]

We can rewrite it as

[tex]3x^2+10x-8=3x^2+12x-2x-8.[/tex]

Now group first two terms and last two terms:

[tex](3x^2+12x)+(-2x-8).[/tex]

The common factor in first two terms is [tex]3x[/tex] and the common factor in last two terms is [tex]-2.[/tex] Use the distributive property for both groups of terms:

[tex]3x^2+12x=3x(x+4),\\ \\(-2x-8)=-2(x+4),[/tex]

so

[tex](3x^2+12x)+(-2x-8)=3x(x+4)-2(x+4).[/tex]

Now you can see that [tex](x+4)[/tex] is a common factor, thus

[tex]3x(x+4)-2(x+4)=(x+4)(3x-2)=(3x-2)(x+4).[/tex]

Since the trinomial can be represented as a product of binomials, this trinomial is not prime.

Answer:

C is the correct answer.

Step-by-step explanation:

Look at the X values for each coordinate pair. If an X value is represented twice with different Y values, it is not a function. If no X value is repeated, or it is repeated but has the same Y value, then it is a function. A has two values for x = 1, B has two values for x = -3, D has two values for x = 7, but C does not, so it is the correct answer.

The question involves understanding exponential growth in Mathematics. The cost of concert tickets is increasing by 8% each day, as calculated using the given prices for two successive days.

The student's question pertains to exponential growth, a concept in Mathematics. Here, the increase in the cost of tickets is an example of exponential growth, where the growth rate is proportional to the current value. You can determine the daily percentage increase by using the formula for exponential growth:[tex](today's cost / yesterday's cost) ^ (^1^ /^ n^u^m^b^e^r^ o^f^ d^a^y^s^ b^e^t^w^e^e^n ^t^h^e^ d^a^t^e^s^) - 1.[/tex]

Here, the cost of the concert was $150 yesterday, and today it is $162. Insert these amounts into the formula, and we get [tex](162 / 150) ^ (^1^ /^ 1^) - 1[/tex]= 0.08 or 8%. Therefore, the ticket prices increase by 8% daily.

#SPJ2

To determine the daily percent increase in the price of concert tickets, use the exponential growth formula. The tickets increased from $150 to $162 in one day, resulting in a calculated daily percent increase of 8%.

The student asked: Tickets for a concert have been in incredibly high demand, and as the date for the concert draws closer, the price of tickets increases exponentially.

A pair of concert tickets cost $150 yesterday, and today is $162. As you complete the parts below, assume that each day's percent increase from the day before is the same.

To find the daily per cent increase, we assume an exponential growth model where ticket prices grow by a constant percentage each day.

Let's denote yesterday's price as P₀ = 150 and today's price as P₁ = 162.

Step-by-Step Explanation:

Define the exponential growth formula: P₁ = P₀ * (1 + r), where r is the daily rate of increase.

→ Substitute the known values into the formula: 162 = 150 * (1 + r).

→ Solve for the rate r: Divide both sides of the equation by 150 to isolate (1 + r).162 / 150 = (1 + r), simplifying to 1.08 = 1 + r.

→ Subtract 1 from both sides to solve for r: r = 0.08.

→ Convert the rate to a percentage: r = 0.08 * 100

                                                          = 8%.

Therefore, the daily percent increase in the price of the concert tickets is 8%.

6. 82°

7. 135°

8. x = 7

9. x = 2

10. x = 1

11. x = 10

Step-by-step explanation:

1. Arc WZ = Arc XY

Arc WZ = 105° Therefore Arc XY = 105°

2. Arc SR = Arc TU

Arc SR = 85° Therefore Arc TU = 85°

3. Arc PQ = Arc QR

Arc PQR = 40° + 40°

Arc PQR = 80°

4. Arc RT = 64°

x = (360° - 64°)/2

x = 296°/2

x = 148°

5. x = 116°

If the chords are congruent to each other, then the arcs are also congruent to each other.

6. x = 82°

If the chords are congruent to each other, then the arcs are also congruent to each other.

7. Arc BC = 90°

x = (360° - 90°)/2

x = 270°/2

x = 135°

8. 2x + 4 = 18

2x = 18 - 4

x = 10

Answer:

Factoring

Step-by-step explanation:

We have the function [tex]x ^ 2 + 5x-6 = 0[/tex]

To factor this expression we must look for two numbers a and b that when adding them give as a result 5 and multiplying them give as a result -6

Then the factorization will have the form

[tex](x + a)(x + b)[/tex]

You can verify that:

[tex]a = 6\\b = -1\\6(- 1) = -6\\6 -1 = 5[/tex]

So:

[tex]x ^ 2 + 5x-6 = (x + 6)(x-1) = 0[/tex]

So:

The solutions are:

[tex]x = -6\\x = 1[/tex]

Frank has 88 oranges at his stand, found by setting up an equation based on the ratio of apples to oranges (6:4) and the total count of fruit (220) and solving for x.

We need to find out the total number of oranges at Frank's fruit stand given that there are 220 fruits in total and the ratio of apples to oranges is 6:4. To do this, let's denote the total number of apples as 6x and the total number of oranges as 4x. The reason behind this is to maintain the ratio of 6 to 4 (or 3 to 2 when simplified). Since the total amount of apples and oranges is 220, we can set up the equation:

6x + 4x = 220

Combining like terms, we get:

10x = 220

Dividing both sides by 10 yields:

x = 22

Now that we have the value of x, we can find the number of oranges (which is 4x) by multiplying 4 by 22:

4x = 4 * 22 = 88

Therefore, Frank has 88 oranges at his fruit stand.
