Answer:

D = 9.80

Step-by-step explanation:

To find AB, we'll use the distance formula:

Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

D = [tex]\sqrt{(10-1)^2+(3-7)^2}[/tex]

D = [tex]\sqrt{(9)^2+(-4)^2}[/tex]

D = [tex]\sqrt{81+16}[/tex]

D = [tex]\sqrt{96}[/tex]

D = 9.80 (Upto 3 sfs)

Answer:

see below

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:

  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:

Volume = 240 feet³

Step-by-step explanation:

We'll find it's volume

Volume = [tex]Lenth *Width*Height[/tex]

Where Length = 4, Width = 6, Height = 10

Volume = 4 * 6 * 10

Volume = 240 feet³

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.

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:

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.

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:

The finding is significant at α = 0.05 but not at α = 0.01.

Step-by-step explanation:

We are given with the following hypothesis below;

Null Hypothesis, [tex]H_0[/tex] : p = 0.40      {means that the population proportion is equal to 40%}

Alternate Hypothesis, [tex]H_A[/tex] : p > 0.40        {means that the population proportion is greater than 40%}

The z-test statistics given to us is 2.25.

Now, at 0.05 level of significance, the z table gives a critical value of 1.645 for the right-tailed test.

Since the value of our test statistics is more than the critical value of z as 2.25 > 1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Now, at 0.01 level of significance, the z table gives a critical value of 2.33 for the right-tailed test.

Since the value of our test statistics is less than the critical value of z as 2.25 < 2.33, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.

This means that the finding is significant at α = 0.05 but not at α = 0.01.

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

Answer:c. F(2)=g(-2)

Step-by-step explanation:

You can use

cos(theta) = u · v / ║u║║v║

that will come out to:

u = 2 x (-4) = -8

v = 3 x (-8) = - 24

u · v = -16

║u║ = [tex]\sqrt{(2)^{2} + (-4)^{2} }[/tex]  = [tex]\sqrt{20} = 2\sqrt{5}[/tex]

║v║ = [tex]\sqrt{(3)^{2} + (-8)^{2} } = \sqrt{73}[/tex]

cos(theta)  = -16/2 [tex]\sqrt{365}[/tex]

and to find (theta), you can now do

theta = (cos^-1) ( -16/2 [tex]\sqrt{365}[/tex])

I don't have a calculator, but you can solve that final problem to find theta
