Answer:

[tex]\frac{1}{256}[/tex]

Step-by-step explanation:

The [tex]4^{-4}[/tex] without exponents is 1/256.

Given,

[tex]4^{-4}[/tex]

We need to write the given expression without exponents.

Exponents are power to a base value.

Example:

a² and b³

a and b are base

2 and 3 are exponents.

We can a fraction into an exponents form and vice versa.

Example:

1/a = [tex]a^{-1}[/tex]

We have,

[tex]4^{-4}[/tex]

Changing into a fraction form

= 1/[tex]4^{4}[/tex]

Find [tex]4^{4}[/tex].

[tex]4^{4}[/tex] = 4 x 4 x 4 x 4 = 16 x 16 = 256

Now,

= [tex]4^{-4}[/tex]

= 1/[tex]4^{4}[/tex]

= 1/256

We get,

= 1/256

Thus the [tex]4^{-4}[/tex] without exponents is 1/256.

Answer:

x = 25 degrees

Step-by-step explanation:

All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.

180 = 99 + 56 + x

180 = 155 + x

25 = x

The unknown angle is equal to 25 degrees.

Answer:

The value of P(B) for independent events = 0.429

Step-by-step explanation:

Given;

P(A) = 0.7

P(A ∩ B) = 0.3

A and B will be independent if  event A will occur and B will also occur, ie A and B will occur independently.

P(A) and P(B) =  P(A ∩ B)  

[tex]P(B) = \frac{ P(A\ n\ B) }{P(A)}\\\\ P(B) = \frac{0.3}{0.7}\\\\P(B) = 0.429[/tex]

Therefore, the value of P(B) for independent events = 0.429

Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.

Step-by-step explanation:

Start by plotting the point (−6,−3). Use the slope formula m=rise/run to identify the rise and the run.

m=2

rise/run = 2/1

rise = 2

run = 1

Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.

Answer:

57 days

Step-by-step explanation:

Given that:

t(0) = 26000

Growth rate (S'(t)) = 80t^1/2

Targeted number of subscribers = 49000

Take the integral of the growth rate :

∫80t^1/2dt = [(80t^(1/2 + 1)) / 1/2 + 1] + C

[(80t^(1/2 + 1)) / 1/2 + 1] + C = (80t^3/2) / 3/2 + C

(80t^3/2) * 3/2 + C = (160/3)t^3/2 + C

(160/3)t^3/2 + C

Let C = t(0)

(160/3)t^3/2 + 26000 = 49000

(160/3)t^3/2 = 49000 - 26000

(160/3)t^3/2 = 23000

Multiply both sides by 3/160

t^3/2 = 23000* 3/160

t^3/2 = 69000/160

t^3/2 = 431.25

t^(3/2 * 2/3) = 431.25^2/3

t = 57.080277

t = 57 days (approx.)

Answer:

4 students got three answers incorrectly.

The number of students got 3 answers incorrect is 4.

A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.

Now from the given histogram following informations are extracted-

Number of students got 1 answer incorrect = 2

Number of students got 2 answer incorrect = 3

Number of students got 3 answer incorrect = 4

Number of students got 4 answer incorrect = 1  

Number of students got 5 answer incorrect = 2

Thus from above we can conclude that,

Number of students got 3 answer incorrect = 4

Thus, the number of students got 3 answers incorrect is 4.

One-sided Limit

Given a piecewise function, we can find the limit when the variable approaches a specific value in the boundary of two pieces.

Special care must be taken to determine what function will be used to calculate the limit according to the conditions of the independent variable.

The given function p(t) has 3 pieces or subfunctions according to different conditions of t. We need to calculate:

[tex]\lim _{x\to 2^{-}}p(t)[/tex]

We must find the subfunction where a value of t is close to 2 but is less than 2.

The correct subfunction is

[tex]p(t)=t^3\qquad -2\le t\le 2[/tex]

Taking the limit:

[tex]\lim _{x\to 2^{-}}p(t)=\lim _{x\to 2}t^3=2^3=8[/tex]

Answer:

a) b. 9

b) c. 4

c) d. 4

Step-by-step explanation:

You are planning to evaluate the mean of a single continuous variable from a study with a sample of n =10 using the t statistic. What are the degrees of freedom for the sample?a. 11 b. 9 c. 10 d. 8

The formula for degree of freedom

= n - 1

n = 10

Degrees of freedom for the sample = 10 - 1

= 9

Option b is correct.

b) With another study, where you also plan on evaluating a mean using the t statistic, you have sample of n =31 that has as SS of 120.

What is the variance for the sample?a. 10.95 b. 14,400 c. 4 d. 2.00

The formula for Variance of a samples = SS(Sum of squares) /n - 1

n = 31

Variance of samples = 120/31 - 1

= 120/30

= 4

Option c is correct

c) For a sample of n =25 that has a sample variance of 400, what is the estimated standard error for the sample?a. 16 b. 17 c. 4.08 d. 4

The formula for standard error =

Standard deviation/√n

We are given Sample variance.

Standard deviation = √400

= 20

Hence, Standard Error = 20/√25

= 20/5

= 4

Option d is correct.

a) The degrees of freedom for the sample is option b. 9.

b) The variance is option c. 4.

c) The standard error is option d. 4.

a.

The formula for degree of freedom

= n - 1

n = 10

Now

Degrees of freedom for the sample should be

= 10 - 1

= 9

b) The variance should be

Since

n = 31

So,

Variance of samples = 120/31 - 1

= 120/30

= 4

c.

The formula for standard error is

= Standard deviation/√n

Here,

Standard deviation = √400

= 20

so, Standard Error = 20/√25

= 20/5

= 4
