Answer:

Approximately \(0.7\; {\rm ft}\).

Step-by-step explanation:

If the current bounce is of height \(h\; {\rm ft}\), the next bounce would be of height \((78\%\, h)\; {\rm ft}\), which is equal to \((0.78\, h)\; {\rm ft}\).

It is given that the first bounce is of height \(6.5\; {\rm ft}\). Relative to this first bounce:

In general, the \(n\)th bounce would have been dampened \((n - 1)\) times. The height of that bounce would be \(((0.78)^{n - 1}\, 6.5)\; {\rm ft}\).

Thus, the \(10\)th bounce would have been dampened \((10 - 1) = 9\) times. The height of that bounce would be \(((0.78)^{10 - 1} \, 6.5)\; {\rm ft} \approx 0.7\; {\rm ft}\) (rounded to the nearest tenth, one digit after the decimal point.)

Answer:

2y = -8x +16

y= -4x+

Step-by-step explanation:

Answer:

y = -4x + 8

Step-by-step explanation:

Formula we use,

→ y = mx + b

Conversion into slope-intercept form,

→ 8x + 2y = 16

→ 2y = -8x + 16

→ y = (-8x + 16)/2

→ y = -4x + 8

Hence, the answer is y = -4x + 8.

The value of radius of a right circular cylinder is 1,248 in for which the minimum surface area is obtained.

Volume of the  right circular cylinder be;

v(c) = 12 in³ =  π*r²*h    

In which, h is the height of the cylinder,

Then , h  =  12 / π*r²

Surface area of a right circular cylinder is:

S = area of base and top  + lateral area

S(A)  =  2*π*r²  + 2*π*r*h  ....eq 1

Put value of 'h' in equation (1)

S(r)  =  2*π*r² +   2*π*r*  ( 12 / π*r²)

S(r)  =  2*π*r² + 24 /r

Differentiate both sides,

S´(r)  =  4*π*r -  24 /r²

Put , S´(r)  = 0 to get the critical points.

4*π*r -  24 /r²  =  0

π*r - 6/r² = 0

π*r³ - 6  = 0

r³   =  1,91    

r = 1,248 in    

Check for the minimum surface area for r = 1,248 in.

Find the second derivative,

S´´(r)  =  4*π  +  48/r³    

S´´(r)  will always be positive.

Thus,  the minimum surface area S  is for   r = 1,248 in.

When displaying any sort of data, it is important to make the table or chart as easy to understand and read as possible without compromising the data. In this case, it is simpler to understand the pie chart if we use as few slices as possible that still makes sense for displaying the data set.

The correct answer is option b) Bacteria in samples 2 and 3 mutated quickly to adjust to temperature change.

From the given graph it is seen that sample 1 is not showing any growth or decline despite of the temperature change. One cannot ascertain its gene expression. On the other hand, Sample 2 shows a slight change from 4cm² to 7cm² bacteria count and Sample 3 shows a wide change as per temperature change from 8cm² to 12cm². Hence it can be said that samples 2 and 3 mutated to adjust to the temperature compared to sample 1 which showed no changes.

Step-by-step explanation:

Answer:

Exponential

Step-by-step explanation:

So lets look at the table.

When x = 1, y = 3

When x = 2, y = 9.

Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.

So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.

This leaves exponential or none of the above.

When x = 3, y = 27

When x = 4, y = 81

This seems like a exponent, since:

3 to the first power is 3

3 to the second power is 9

3 to the third power is 27

and 3 to the fourth power is 81

According to given information, the length of the rectangular storage unit is 12 feet.

What is rectangle?

A rectangle is a two-dimensional shape with four sides and four right angles. It is a quadrilateral with opposite sides that are parallel and equal in length.

We can use the Pythagorean theorem to find the length of the storage unit. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the 5-foot-wide floor and the length of the storage unit form the two sides of a right triangle, with the diagonal (the distance from one corner to the opposite corner) being the hypotenuse. We can set up the equation as:

\(hypotenuse^2 = side1^2 + side2^2\)

where side1 = 5 feet and hypotenuse = 13 feet.

Simplifying this equation, we get:

\(hypotenuse^2\)\(= 5^2 + side2^2\)

169 = 25 + \(side2^2\)

\(side2^2\) = 144

side2 = 12

Therefore, the length of the storage unit is 12 feet.

The series diverges, and there is no sum for this series.

To find the Nth partial sum of the infinite series and evaluate its limit, we first need to analyze the given series. The series is represented as:

Σ (1 / (n + 7))

To determine whether the series converges or diverges, we can use the Comparison Test. Let's compare the given series with another series, 1/n. Since 1/n is a harmonic series and it diverges, if our given series also diverges, it must satisfy the inequality:

1 / (n + 7) >= 1 / n

Now, let's find the Nth partial sum (S_N) and evaluate its limit:

Step 1: Write the general term of the series:

a_n = 1 / (n + 7)

Step 2: Find the Nth partial sum S_N:

S_N = Σ (1 / (n + 7)) from n=1 to N

Step 3: Evaluate the limit of S_N as N approaches infinity:

lim (S_N) as N -> ∞

Since 1 / (n + 7) >= 1 / n, the limit of S_N as N approaches infinity will also be infinity. Therefore, the series diverges, and there is no sum for this series. If the series were convergent, we would be able to find its sum, but since it diverges, the answer is DNE (Does Not Exist).

So, The probability that randomly chosen Sample of so residents from each of the two states. The proportion of women in Alaska logger than in Rhodes island is 0.3556.

Given that based on the latest U.S census Count, only 48% of Alaskans are females white 51.7% of Rhode islanders are female.

Let x denote the females in Alaska and y denote the females in Rhode island.

Since, 48% Alaskans ore females.

So, P(x)=0.48

And 51.7 \% of Rhode islanders are females

So, P(y)=0.517.

Now, randomly chosen sample of so residents

Options a, b, d, and g are the correct conditions for a Binomial Distribution.

The four conditions necessary for X to have a Binomial Distribution are:

a. There are n set trials: In a binomial distribution, the number of trials, denoted as "n," must be predetermined and fixed. Each trial is independent and represents a discrete event.

b. The trials must be independent: The outcomes of each trial must be independent of each other. This means that the outcome of one trial does not influence or affect the outcome of any other trial. The independence assumption ensures that the probability of success remains constant across all trials.

d. There can only be two outcomes, a success and a failure: In a binomial distribution, each trial can have only two possible outcomes. These outcomes are typically labeled as "success" and "failure," although they can represent any two mutually exclusive events. The probability of success is denoted as "p," and the probability of failure is denoted as "q," where q = 1 - p.

g. The probability of success, p, is constant from trial to trial: In a binomial distribution, the probability of success (p) remains constant throughout all trials. This means that the likelihood of the desired outcome occurring remains the same for each trial. The constant probability ensures consistency in the distribution.

The remaining options, c, e, and f, are not conditions necessary for a binomial distribution. Option c, "Continue sampling until you get a success," suggests a different type of distribution where the number of trials is not predetermined. Options e and f, "You must have at least 10 successes and 10 failures" and "The population must be at least 10x larger than the sample," are not specific conditions for a binomial distribution. The number of successes or failures and the size of the population relative to the sample size are not inherent requirements for a binomial distribution.

We can extend our definition of the average value over a continuous function to an infinite interval by defining the average value f on the interval [0, ∞) to be      \(\lim_{t \to \infty}\frac{1}{t-a}\int\limits^t_a {f(x)\\} \, dx\)  .

The definition of the average value of a continuous function f(x) can be expanded to include the infinitely long interval [a,∞] as follows:

\(\lim_{t \to \infty}\frac{1}{t-a}\int\limits^t_a {f(x)\\} \, dx\)

Let's assume that f(x) is any continuous function. Assume that the integral \(\int\limits^i_0 {f(x)} \, dx\)   is divergent and that f(x)≥0 in the range [a,∞].

Show that, if this limit exists, \(f_{ave} = \lim_{x \to \infty} f(x)\) .
