Answer:

The answer is [tex]12\log{(x(x-2))}[/tex]

Step-by-step explanation:

Exponential property of logarithm:

We have that:

[tex]a \log{x} = \log{x^{a}}[/tex]

Sum of logarithms:

We have that:

[tex]\log{a} + \log{b} = \log{ab}[/tex]

Applying the exponential property:

[tex]3\log{x} = \log{x^3}[/tex]

[tex]4\log{(x-2)} = \log{(x-2)^4}[/tex]

So

[tex]3\log{x} + 4\log{x-2} = \log{x^3} + \log{(x-2)^4}[/tex]

Additive property

[tex]\log{x^3} + \log{(x-2)^4} = \log{x^3(x-2)^4} = \log{(x(x-2))^12}[/tex]

Exponential property:

[tex]\log{(x(x-2))^12} = 12\log{(x(x-2))}[/tex]

The answer is [tex]12\log{(x(x-2))}[/tex]

Answer:

The right answer is:

(a) 0.205

(b) 0.005425

Step-by-step explanation:

The given data is:

0.213, 0.204, 0.208, 0.200, and 0.198

(a)

The mean will be:

= [tex]\frac{Sum \ of \ all \ data}{No. \ of \ data}[/tex]

= [tex]\frac{0.213+ 0.204+ 0.208+ 0.200+0.198}{5}[/tex]

= [tex]\frac{1.023}{5}[/tex]

= [tex]0.2046[/tex]

or,

= [tex]0.205[/tex]

(b)

The standard deviation will be:

[tex]\sigma^2=\Sigma\frac{(x_i-\mu)^2}{N}[/tex]

    [tex]=\frac{(0.213-0.2046)^2+...+(0.198-0.2046)^2}{5}[/tex]

    [tex]=\frac{0.0001472}{5}[/tex]

    [tex]=2.994\times 10^{-5}[/tex]

or,

    [tex]=0.005425[/tex]

Answer: Hi Your question lacks some information but i will give you a general solution with similar data found online

answer

a) 15.15%

b) The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

Step-by-step explanation:

Using The probit regression

from the attached question ;

for smoking

1 = smokes , 0 = do not smoke

For Independent variable

1 = ban at workplace ,  0 = not ban at workplace.

sex :  male = 0 , female = 1

a) Assuming Mr. A is not subject to a workplace smoking ban

P ( Mr. A  smokes ) = 15.15%

b) Assuming Mr. A is subject to a workplace smoking ban

determine effect  on P ( Mr. A smokes )

The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

Answer:

Step-by-step explanation:

Marina,  everyone has a tough time with this type of math problem,   just send me a note if you get stuck on these.   :P

You're given two points,  

P1 = (-4,8)  in the form (x1,y1)

P2 = (1,3)   in the form (x2,y2)   ( I made the forms, so can you )

slope = m

m = (y2-y1) / (x2-x1)

m = (3-8) / ( 1 - (-4))

m = -5 / (1 + 4)

m = -5 / 5

m = -1

now use the point-slope formula

y-y1=m(x-x1)

y-(8) = -1(x-(-4))

y-8 = -1(x+4)

y-8 = -x -4

y = -x-4+8

y = -x +4

That's the equation  :P

Answer: 2/3πx³

Step-by-step explanation:

Let the radius of the cone be represented by x.

Since the height of the cone is twice the radius of its base, the height will be: = 2x

Volume of a cone = 1/3πr²h

where,

r = x

h = 2x

Volume of a cone = 1/3πr²h

= 1/3 × π × x² × 2x

= 1/3 × π × x² × 2x

= 1/3 × π × 2x³

= 2/3πx³

Therefore, the correct answer is 2/3πx³.

Answer:

0.29

Step-by-step explanation:

Total number of students = 35

Number of students who got B = 10

Probability that a student earns grade B :

Probability = required outcome / Total possible outcomes

P(grade B) = 10 / 35 = 0.2875

= 0.29

Answer:

{ 8, 2}

Step-by-step explanation:

Basic algebra, the object which is not in a set quantity, which we have to find, is the "some vans" and the "some buses"

So let the number of van be x

Let the number of buses be y

So, since there are 10 vehicles,

x+y=10

Makes sense right

Now, it says that every car can carry 6 students, and every van can carry 35 students, so in another way, we could represent this by saying

6 x Number of van + 35 x Number of buses

thus,

6x + 35y

And since 118 students went on the field trip, this means that

6x +35y = 118

So now we have two equations,

x + y = 10

6x + 35y = 118

We can solve this with substitution

x + y = 10

x = 10 - y

Thus, x = 10-y

Put this in this

6(10-y)+ 35y= 118

60-6y+35y=118

60+29y=118

29y=118-60

29y= 58

y = 58/29

y = 2

Thus, the number of buses, y, is 2

Now since there are 10 vehicles, and 2 are buses, then the other are 8 van

Answer:

8.2 m

Step-by-step explanation:

To solve the problem, we use pythagorean theorem, which is a^2 + b^2 = c^2. We are given both the legs, so we can substitute them in:

8^2 + 2^2 = c^2

And simplify to get:

c^2 = 64 + 4

c^2 = 68

Now, we find the square root of both sides to isolate c:

c = √68

√68 is approximately 8.24621125124

This rounded to the nearest tenth is 8.2 m

Answer:

The appropriate solution is:

(1) 22.81 minutes

(2) 0.171

Step-by-step explanation:

According to the question, the values will be:

The service rate of guess will be:

= [tex]5+3.5[/tex]

= [tex]8.5 \ minutes[/tex]

The mean arrival rate will be:

[tex]\lambda =\frac{60}{5}[/tex]

  [tex]=7.5 \ cabs/hr[/tex]

The mean service rate will be:

[tex]\mu= 7.05 \ cabs/hr[/tex]

(1)

The average time a cab must wait will be:

⇒ [tex]W_q=22.95-\frac{1}{7.05}[/tex]

⇒       [tex]=\frac{161.798-1}{7.05}[/tex]

⇒       [tex]=\frac{160.798}{7.05}[/tex]

⇒       [tex]=22.81 \ minutes[/tex]

(2)

The required probability will be:

⇒ [tex]P(X\geq 6)=\frac{1-2.115}{1-7.5}[/tex]

⇒                  [tex]=\frac{-1.1115}{-6.5}[/tex]

⇒                  [tex]=0.171[/tex]

Answer:

38

Step-by-step explanation:

The range is the difference between the highest value and the lowest value. Here the highest value is 55 and the lowest 17. Therefore, the range is take away 17 from 55 which equals to 38

The range for this set of data is 38.

Option B is the correct answer.

The range is a measure of dispersion or spread in a set of data.

It is defined as the difference between the largest and the smallest values in the data set.

Range provides an idea of how much the data values are spread out or dispersed.

If the range is small, it indicates that the data values are close together, while a large range indicates that the data values are spread over a wider range of values.

We have,

To find the range of a set of data, we need to subtract the smallest value from the largest value.

Here, the smallest value is 17 and the largest value is 55.

So,

The range of the data set is:

55 - 17 = 38

Thus,

The range for this set of data is 38.

Answer:

Step-by-step explanation:

3 time 2 with the power of t

You see the given values, 1 and 4?

All you need to do is replace those values with 1 and 4.

3 x 2 with the power of 1.

2 times the power of one is just 2 because you aren't multiplying it with another 2.

So, 3 times 2 is 6.

3 x 2 with the power of 4

2 x 2 x 2 x 2 = 16

It's not 2 times 4; it's 2 times the power of 4-- which means we multiply the number by itself depending on the given value we're given.
