Answer:

a. +3

b. -12a

Step-by-step explanation:

Here, we want to know the steps that are involved in those unoccupied segments

let’s start with the output

6a + 18

So what turned a to 6a + 18

Let’s call that output x

Let’s reverse the last step that multiplied that term and a

Thus (6a + 18)/6 = a + 3

Thus the x-term we are looking for is + 3 before the multiplication by 6

Now for the second part;

a * 4 -3 = -12a

Answer:

0.75 or 3/4

Step-by-step explanation:

If we call the common ratio r, since 4 - 1 = 3 we can write:

64 * r³ = 27

r³ = 27/64

r = ∛(27/64) = ∛27 / ∛64 = 3 / 4

Answer:

(a) the common ratio = 3/4.

Step-by-step explanation:

First term a1 = 64

The fourth term a4 = a1 r^3 = 27

So a1 r^3 / a1 = 27/64

r^3 =  (27/64)

r = ∛ (27/64

= 3/4.

Answer:

  no

Step-by-step explanation:

In ∆XYZ, we can write the ratios of the sides from shortest to longest as ...

  y : z : x = 1 : 1.5 : 2 = 2 : 3 : 4

In ∆QSR, we can write the ratios of the side lengths from shortest to longest as ...

  r : s : q = 0.5 : 1 : 1.5 = 1 : 2 : 3

Based on side lengths only, the triangles cannot be similar.

__

Additional note

Even if shortest-to-longest side ratios were the same, the triangle naming is incorrect for them to be similar.

Answer:

These are squares of numbers 8 to 4.

Step-by-step explanation:

The given sequence of numbers is given as:

64, 49, 36, 25, 16

First of all let us factorize each number:

[tex]64 = 8 \times 8\\49 = 7 \times 7\\36 = 6 \times 6\\25 = 5\times 5\\16 = 4\times 4\\[/tex]

We can see that every number is obtained by multiplying some other number by itself.

For example, 64 is obtained by multiplying 8 with itself i.e. 8 multiplied with 8.

49 is obtained by multiplying 7 with itself i.e. 7 multiplied with 7.

and so on.

So, each number is a square of some number.

The numbers are in decreasing order. (64 to 16)

i.e. we have square of numbers here.  

Square of 8, square of 7, square of 6, square of 5, square of 4,

Generalizing the terms:

[tex]a_n = (9-n)^2[/tex] where n is from 1 to 5

The name given to the sequence is:

Square of (9-n) where n is from 1 to 5.

OR

square of numbers, numbers from 8 to 4 in decreasing order.

Answer:

2nd Graph

Step-by-step explanation:

If it's a direct proportional relationship, the the 2nd graph is your best choice. Usually renting stuff keeps increasing in price (like a linear graph) as businesses want to make money continuously. Besides, it's charged by the hour, with an increase of price proportional to the amount of hours, so it is a linear equation.

Answer:

Inga will have to sell $12,533 to earn more in commission than in salary.

Step-by-step explanation:

As the commission is the percentage of sales amount so, need to calculate the minimum sales value required.

Igna's salary = $375

Commission rate = 3%

Sale to earn more than salary = $376 / 3% = $12,533.33

Igna has to make a minimum sale of $12,533 per week in order to earn more commission than her salary.

Answer:

The standard deviation of second data set is 9.2952.

Step-by-step explanation:

The variance of a random variable is independent of change of origin but not of scale.

That is if any value is added or subtracted from the random variable then the variance of the random variable will not change.

[tex]V(X+a)=V(X)+V(a)=V(X)[/tex]

And if any value is multiplied or divided by the random variable then the variance of the random variable will change.

[tex]V(aX)=a^{2}V(X)[/tex]

The first set of data is:

S₁ = {3, 4, 6, y, (y+3) and 9}

The variance of S₁ is,

V (S₁) = 21.6

The second set of data is:

S₂ = {6, 8, 12, 2y, (2y+6) and 18}

On comparing the two sets of data, it can be concluded that:

S₂ = 2 × S₁

Compute the variance of S₂ as follows:

[tex]V(S_{2})=V(2\times S_{1})[/tex]

         [tex]=2^{2}\times V(S_{1})\\\\=4\times 21.6\\\\=86.4[/tex]

Then the standard deviation of S₂ is:

[tex]SD(S_{2})=\sqrt{V(S_{2})}[/tex]

            [tex]=\sqrt{86.4}\\=9.2952[/tex]

Thus, the standard deviation of second data set is 9.2952.

Answer:

x = 12.5

Step-by-step explanation:

Since measure of 4th arc is not given (measure of 3 arcs have been given), we will apply the following theorem.

By the intersecting chords theorem,

"If two chords intersecting inside a circle, measure of the angle between these chords will measure the half the sum of measures of arcs intercepted by the angle and its vertical angle."

Here intercepted arcs are (2x)° and 155°. Angel between the chords measure 90°.

By the theorem,

90° = [tex]\frac{1}{2}(2x + 155)[/tex]°

180° = (2x + 155)°

2x = 180 - 155

2x = 25

x = 12.5

Step-by-step explanation:

1. The percentage of the players who finished the walk in less than 2 hours  will be  2.28%

2. The probability that two randomly chosen players completed the walk in 2.9 hours or more was 15.87%

3. The probability that four randomly chosen players completed the walk was between 1.7 and 2.9 hours  84%

4. The number of participants who complete the walk in more than 3.5 hours, given that there are 1,200 participants 0

5. if the number of participants increased, the probability would increase while if they decreased, the probability would decrease

The z score is a measure used in probability to determine the number of standard deviations the raw score is above or below the mean, it is given by the equation:

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

Given that:

the mean μ = 2.6 hours and a standard deviation(σ) of 0.3 hours.

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

1) What percent of the players finished the walk in less than 2 hours.

To calculate this, we use x as 2 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2-2.6}{0.3}=-2[/tex]

From the normal probability distribution table, P(x < 2) = P(z < -2) = 0.0228 = 2.28%

2)  What is the probability that two randomly chosen players completed the walk in 2.9 hours or more

To calculate this, we use x as 2.9 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2.9-2.6}{0.3}=1[/tex]

From the normal probability distribution table, P(x > 2.9) = P(z > 1) = 1-P(z<1) = 1 - 0.8413 = 0.1587

3. What is the probability that four randomly chosen players completed the walk between 1.7 and 2.9 hours

To calculate this, we first use x as 1.7 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{1.7-2.6}{0.3}=-3[/tex]

For x as 2.9 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2.9-2.6}{0.3}=1[/tex]

From the normal probability distribution table, P(1.7 < x < 2.9) = P(-3 < z < 1) = P(z<1) - P(z < -3) = 0.8413 - 0.0013 = 0.84

4. What observations can you make about the number of participants who complete the walk in more than 3.5 hours, given that there are 1,200 participants?

To calculate this, we use x as 3.5 hours, a number of samples (n) = 1200, and then find the z score.

[tex]Z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}=\dfrac{3.5-2.6}{\dfrac{0.3}{\sqrt{1200}}}=104[/tex]

From the normal probability distribution table, P(x > 3.5) = P(z > 104) = 1-P(z<104) = 1 - 1 = 0

5. What might you observe if the number of participants increased or decreased?

if the number of participants increased, the probability would increase while if they decreased, the probability would decrease

Answer:

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Step-by-step explanation:

Let A denote Annie and X denotes Xenas.

The total time is 2 hours (2:00 to 4:00)

Both A and X stays for 45 minutes or 3/4 hours

The probability that A and X do not meet is given by

P(Not meet) = (3/4)/2 × (3/4)/2

P(Not meet) = 9/64

So the probability that A and X will meet is given by

P(meet) = 1 - P(Not meet)

P(meet) = 1 - 9/64

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Los dos valores faltantes podrían ingresarse utilizando varios métodos, incluyendo la mediana, modal y el valor medio de los datos dados en la distribución.

Aquí usaremos el valor medio.

Media (m) de los datos = suma de la observación / número de observaciones Media =

(55 + 51 + 60 + 56 + 64 + 56 + 63 + 63 + 61 + 57 + 62 + 50 + 49 + 70 + 72 + 54 + 48 + 53 + 58 + 66 + 68 + 45 + 74 + 65 + 58 + 61 + 62 + 59 + 64 + 57 + 63) / 31 = 1844/31 = 59.4 = 59 (al número entero más cercano) Entonces reemplace los valores faltantes con 59.

En otro para hacer cálculos sobre los datos, hay que reorganizarlos.

Datos ordenados: 45,48,49,50,51,53,54,55,56,56,57,57,58,58,59,59,59,60,61,61,62,62,63,63,63, 64,64,65,66,68,70,72,74

Los cuartiles de datos:

Primer cuartil (Q1) = 1/4 (33 + 1) = 1/4 (34) = 8.5

Q1 = (8º + 9º) / 2 = (55 + 56) = 111/2 = 55,5

Segundo cuartil (Q2) = Q3 - Q1 = (25.5 - 8.5) = 17th = 59

Tercer cuartil (Q3) = 3/4 (33 + 1) = 3/4 (34) = 25.5 Q3 = (25 + 26) = (63 + 64) = 127/2 = 63.5

Rango intercuartil (IQR) = 63.5 - 55.5 = 8

Step-by-step explanation:

If we look at ∠CBA and ∠BAE, we notice that they must be supplementary because they are same side interior angles, therefore:

41 + 102 + x = 180

143 + x = 180

x = 37°

Answer:

x = 37°

Step-by-step explanation:

→ First, we need to remember 2 important angle facts

→ The first thing we want to do is find BCA because it's alternate to CAE or angle x, so let's set up an equation

BCA + 41° + 102° = 180°

→ Add the whole number together

BCA + 143° = 180°

→ Minus 143° from both sides to isolate BCA

BCA = 37°

→ Using the second angle fact, that alternate angles are equal, we can confirm that angle 'x' and angle BCA are alternate therefore equal

x = 37°

Answer:

WX = 7.9

Step-by-step explanation:

By applying tangent rule (law of tan) in the given right triangle WXY.

tan(W) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(27)° = [tex]\frac{\text{XY}}{\text{WX}}[/tex]

0.509525 = [tex]\frac{4}{\text{WX}}[/tex]

WX = [tex]\frac{4}{0.509525}[/tex]

WX = 7.85

WX ≈ 7.9

Therefore, length of side WX is 7.9 units.

Answer:

11/50

Step-by-step explanation:

The frequency numbers for landing on 1, 2, and 3 are:

25, 53, 62.

We add them up to get: 25 + 53 + 62 = 140

Since 250 spins were made, and 140 of them landed on 1, 2, or 3, then

250 - 140 = 110,

so 110 landed on 4 or 5.

We are told the numbers of spins landing on 4 and 5 are equal, so

110/2 = 55,

so the spinner landed 55 times on 4 and 55 times on 5.

relative frequency = 55/250 = 11/50
