The probability of getting e's not next to each other is 0.05.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that the letters of the word `sixteen' are randomly arranged.

The arrangement of the e's not to come next to each other is, 3! and the total arrangement will be 5!

The probability will be calculated as,

P = (3!/5!)

P = (3x 2) / (5x4x3x2x1)

P = 1 / 20

P = 0.05

Therefore, the probability of getting e's not next to each other is 0.05.

Margin of error is statistical expressing the amount of a random sampling error in survay results not the error term from biased sampling method. So, correct answer is False.

Margin of error in statistics represents the amount of random sampling error in the survey results. The larger the margin of error, the less confident that the survey results reflect the results of the census of the entire population. It is denoted by E or MOE. It is calculated by dividing the square root of the sample size by the standard deviation of the population. 99% level is the most conservative, 90% level is the least conservative. The sampling error is a statistical error that occurs when the analyst does not select a sample that is representative of the entire data population.

False - Margin of error only account for sample variability (the fact that my sample differs from many others' samples and therefore provides different statistics.

Answer:

64 units sqr.

Step-by-step explanation:

If the frame is 2 units wide, there is 4 units total on the top and bottom, extra. So, adding that to our units, it is 7+4 = 11 by 5+4 = 9  NINE BY 11. 9*11 = 99, and 99-35 = 64. So it is 64

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

so the correct answer is A.

A 4(3+6)=12+24

B (4+3)+6=6+(4+3)

C (12+4)+0=12+4

D​ (12+4)+6=12+(4+6)

Answer:

A) 0 ≤ n ≤ 7

B) initial height of plant = 8 cm

C) average rate of change = 0.475 cm/day.  

Plant grew an average of 0.475 cm per day from day 2 to day 6

Step-by-step explanation:

\(f(n)=8(1.05)^n\)

Part A

Given height = 11.26 cm

\(\implies 8(1.05)^n=11.26\)

\(\implies(1.05)^n=\dfrac{11.26}{8}\)

\(\implies(1.05)^n=1.4075\)

Taking natural logs:

\(\implies \ln(1.05)^n=\ln(1.4075)\)

\(\implies n\ln(1.05)=\ln(1.4075)\)

\(\implies n=\dfrac{\ln(1.4075)}{\ln(1.05)}\)

\(\implies n=7.005819448\)

\(\implies n \approx7\)

Therefore, the scientist concluded his study after 7 days, so the domain is 0 ≤ n ≤ 7

Part B

y-intercept is when the curve intersects the y-axis (when n = 0):

\(\implies f(0)=8(1.05)&^0=8\times1=8\)

The y-intercept represents the initial height of the plant, which is 8 cm

Part C

Rate of change = change in y ÷ change in x

⇒ rate of change = change in f(n) ÷ change in n

\(\implies f(2)=8(1.05)^2=8.82\)

\(\implies f(6)=8(1.05)^6=10.72076513...\)

\(\implies \textsf{rate of change} \ =\dfrac{f(6)-f(2)}{6-2}=0.4751912813...\)

So the average rate of change was 0.475 cm/day.  This indicates that the plant grew an average of 0.475 cm per day from day 2 to day 6 (over a period of 4 days).

ETA: please see attached graph.  The gray dotted curve is the function, and the black solid curve is the function with the restricted domain of 0≤n≤7 since the study took 7 days.

Stephanie Ambrose's annual base premium is $594.19. b.

To calculate Stephanie Ambrose's annual base premium, we need to add her base premium for bodily injury and property damage limits to the premiums for comprehensive and collision insurance.

Given:

Base premium for bodily injury and property damage limits:

$292.50

Premium for $50-deductible comprehensive insurance: $75.90

Premium for $50-deductible collision insurance: $225.79

To calculate the annual base premium, we sum up all these values:

Annual Base Premium = Base Premium + Comprehensive Premium + Collision Premium

Annual Base Premium = $292.50 + $75.90 + $225.79

Calculating this sum gives us:

The innovation that was made possible in part because of the Carterfone decision in 1968 is the public Internet. The correct answer is option C

The Carterfone decision was a landmark ruling by the Federal Communications Commission (FCC) that allowed for the interconnection of third-party devices to the telephone network. Prior to this decision, telephone companies had a monopoly on the equipment that could be used on their networks, and customers were not allowed to attach their own devices.

This decision paved the way for the development of the public Internet by allowing for the interconnection of third-party devices to the telephone network, which enabled the creation of new technologies, such as modems. Without the Carterfone decision, the public Internet as we know it today may not have been possible.

The space cost you $833.33. per MONTH

To calculate the monthly cost, we first need to determine the annual cost of the space.

Given that the cost is $10 per square foot per year, we know, there are 12 months in an year and the space is 1,000 square feet, the annual cost of the space would be:

Annual cost = the space  * cost

Annual cost = 1,000 square feet * $10/square foot = $10,000

To convert this to monthly cost, we divide the annual cost by 12 (the number of months in a year):

Monthly cost = $10,000 / 12 = $833.33

B. We are to describe the relationship between bridge length and breaking weight.

To do this, we need to check the graph.

In doing that, we will see that the breaking weight appears to decrease as the Bridge length increases.

We can conclude then that the breaking weight and bridge length have an inverse relationship.

That is shown in the graph.

The highest value of the breaking weight is 14 and that is when the value of bridge length is at its lowest (4).

The lowest value of the breaking weight is 3 and that is when the value of the bridge length is at its highest (11)

Hence, there is an inverse relationship between them.4)

This formula uses the logical connectives "and" and "or" to combine the statements Q(x, y) for all possible values of x and y. The "and" connects the statements for x=0 and x=1, ensuring that both sets of possibilities are considered. The "or" connects the statements for each possible value of y, allowing for any value of y to satisfy the condition.

Option A is incorrect because it uses the connective "1" which is not a valid logical connective. Option B is incorrect because it uses the connective "or" to combine the statements for each possible value of y, which does not allow for all possibilities to be considered.

The largest figure that Ash can built with 61 toothpicks is of:

A composition of 12 hexagons.

The number of toothpicks needed is modeled with a linear function, defined as follows:

y = mx + b.

The coefficients of the function are given as follows:

The number of toothpicks in each figure is represented by the following sequence:

(6, 11, 16, ...).

Hence the parameters are given as follows:

m = 5, b = 6.

Thus the definition of the function is of:

T(n) = 5(n - 1) + 6. (as the first figure is with n = 1).

T(n) = 5n + 1.

Then the number of hexagons with 61 toothpicks is obtained as follows:

5n + 1 = 61

5n = 60

n = 60/5

i had this same question lol

Wilbur's flight took about 43.7 seconds.

Let x be the rate of Orville in feet per second and 2x be the rate of Wilbur in feet per second. Let t be the time it took for Orville to complete the flight and t - 6 be the time it took for Wilbur to complete the flight.

We know that the distance traveled by both brothers is the same, which we can express with the equation:

distance = rate × time

For Orville:

distance = x * t

For Wilbur:

distance = 2x * (t - 6)

Since the distance is the same for both brothers, we can set the two equations equal to each other:

x * t = 2x * (t - 6)

Expanding and simplifying the right-hand side:

xt = 2xt - 12x

12x = xt

x = t/12

So, Orville's rate is x = t/12 feet per second.

Substituting this into one of the equations for distance, we can solve for t:

distance = x * t

852 = (t/12) * t

852 = t² / 12

t² = 12 * 852

t² = 10224

t ≈ 101.1 seconds (rounded to the nearest tenth)

So, Orville's flight took about 101.1 seconds.

Now we can use the equation for Wilbur's distance to find his rate:

distance = 2x * (t - 6)

852 = 2(2x) * (101.1 - 6)

852 = 4x * 95.1

x ≈ 5.64 feet per second (rounded to the nearest hundredth)

So, Orville's rate is about 5.64 feet per second, and Wilbur's rate is twice that or about 11.28 feet per second.

To find Wilbur's time, we can use the equation for distance again:

distance = 2x * (t - 6)

852 = 2(11.28) * (t - 6)

852 = 22.56t - 135.36

22.56t = 987.36

t ≈ 43.7 seconds (rounded to the nearest tenth)

So, Wilbur's flight took about 43.7 seconds.

Step-by-step explanation:

In triangle AMD,

h² = p² + b²

or, h² = 6² + 4²

or, h²= 36 + 16

so, h² = 52

so, AM² = 52

Take x as reference angle,

cos²x = 16/52

Now,

In triangle, AMK,

Taking x as reference angle,

cos²x = b²/h²

cos²x = AM²/MK²

or, cos²x = 52/MK²

Now,

cos²x = 16/52 = 52/MK²

or,

16/52 = 52/MK²

or, 16MK² = 2704

or, MK² = 2704/16

A linear function has a constant rate of change. To find the equation of the function, we need to determine the slope and y-intercept.

Using the given points, we can calculate the slope as:

slope = (change in y) / (change in x)

= (3 - 10.5) / (-0.5 - (-3))

= -7.5 / 2.5

= -3

To find the y-intercept, we can use one of the points and the slope in the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept.

Using the point (-0.5, 3), we can substitute the slope and solve for b:

3 = (-3)(-0.5) + b

3 = 1.5 + b

b = 1.5

Therefore, the equation that represents the same relationship as the given points is:

y = -3x + 1.5
