Step-by-step explanation:

Answer:

Let n represent the number

One half of a number= ½ n

Now, the equation will be=

½ n =14+2n

On multiplying both sides by 2, we obtain

n=2(14+2n)

n=28+4n

On subtracting 4n from both the sides,we obtain

n-4n=28

-3n=28

On dividing both sides by -3, we obtain

n= -28/3

Answer:

y = 2^(x - 4)

Step-by-step explanation:

f(g(x)) = f(x - 4) = 2^(x - 4)

p = 27

r = 0

p(1+r3) = 27

27(1+0(3)) = 27

Answer:

The probability of selecting a male is 0.3151.

The events "male" and "driver" are not independent.

The correct option is B.

Step-by-step explanation:

The missing data is as follows:

                    Female          Male          Total

Driver            32759          11715          44474

Passenger      6534           6361          12895

Total              39293         18076          57369

The complete question is:

Determine ​P(​male) and ​P(male​|driver​). Are the events ​"male​" and ​"​driver" ​independent?

Solution:

Compute the probability of selecting a male as follow:

[tex]P(M)=\frac{n(M)}{N}=\frac{18076 }{57369}=0.3151[/tex]

Thus, the probability of selecting a male is 0.3151.

Compute the probability of selecting a male given that he is a driver as follows:

[tex]P(M|D)=\frac{P(M\cap D)}{P(D)}=\frac{n(M\cap D)}{n(D)}=\frac{11715 }{44474}=0.2634[/tex]

Two events, say A and B, are independent if:

P (A|B) = P(A)

Here, P (M|D) ≠ P (M)

Thus, the events "male" and "driver" are not independent.

P(female)= .317

Determine P(femaleIpassenger)= .264

No. The occurrence of the event

​"passenger​" affects the probability of the event ​"female​."

Answer:

Step-by-step explanation:

the "mean" just means the "average"

So if the average of four numbers  = 2.6

To find the total of the four numbers, you would multiply 2.6 by 4.

2.6 x 4 = 10.4

One of the four numbers is 5. (given in the question)

This means that the total of the remaining three numbers is:

10.4 - 5 = 5.4

Then divide 5.4 by 3 to find the average of the 3 numbers.

Mean of the other 3 numbers = [tex]\frac{5.4}{3}[/tex] = ?

Answer:

2,3

Step-by-step explanation:

The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.

Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.

The formula for slope of a line that passes through two points (x₁.y₁) and (x₂,y₂) is,

y₂ - y₁ = m(x₂ - x₁)

The given points are, (1, 1) and (7, 5).

The slope of the line is given by formula m = (y₂-y1)/(x₂-x₁)

m= (5-1)/(7-1)

m = 4/6

m = 2/3

The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.

Answer:

What is 198/264 Simplified?

3/4 is the simplified fraction for 198/264.

Step-by-step explanation:

Answer:

3/4.

Step-by-step explanation:

Find the prime factors:

198 =  2 * 99

99 = 3 * 3 * 11

So 198 = 2 * 3 * 3 * 11.

264 = 4 * 66 = 2 *2 * 66

66 = 2 * 3 * 11

So 264 = 2 * 2 * 2 * 3 * 11.

Now we find the Greatest common factor os the 2 numbers:

It is 2 * 3 * 11 = 66.

Therefore we can now simplify the fraction:

198/66 / 264/66

= 3/4.

Answer:

The 95% confidence interval for the standard deviation is (0.14, 0.54).

Step-by-step explanation:

The complete data and question is:

Sloth CW Ratios ; {1.5 , 1.09 , 0.98 , 1.42 , 1.49 , 1.25}

The 95% confidence interval for the standard deviation of this data is  < σ <   (two decimals - include the leading zero) .

Solution:

Compute the sample standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{6}\times 7.73=1.2883\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{6-1}\times 0.2387}=0.2185[/tex]

The (1 - α)% confidence interval for the variance is:

[tex]CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}<\sigma^{2}<\frac{(n-1)s^{2}}{\chi^{2}_{1-\alpha/2}}[/tex]

Confidence level = 95%

⇒ α = 0.05

The degrees of freedom is,

df = n - 1 = 6 - 1 = 5

Compute the critical values of Chi-square:

[tex]\chi^{2}_{\alpha/2, (n-1)}=\chi^{2}_{0.025,5}=12.833\\\\\chi^{2}_{1-\alpha/2, (n-1)}=\chi^{2}_{0.975,5}=0.831[/tex]

*Use a Chi-square table.

Compute the 95% confidence interval for the variance as follows:

[tex]CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}<\sigma^{2}<\frac{(n-1)s^{2}}{\chi^{2}_{1-\alpha/2}}[/tex]

     [tex]=\frac{5\times (0.2185)^{2}}{12.833}<\sigma^{2}<\frac{5\times (0.2185)^{2}}{0.831}\\\\=0.0186<\sigma^{2}<0.2873\\\\=\sqrt{0.0186}<\sigma<\sqrt{0.2873}\\\\=0.1364<\sigma<0.5360\\\\\approx 0.14<\sigma<0.54[/tex]

Thus, the 95% confidence interval for the standard deviation is (0.14, 0.54).
