how can you write a percent greater than 100 or less than 1 as a fraction and as a decimal?

Answer:

Square root of 85

Step-by-step explanation:

We can envision the segment AB as the hypotenuse of a right triangle with a height of 6 units and a length of 7 units. We can use the Pythagorean Theorem to solve for the length of segment AB which is similar to distance formula.

6^2 + 7^2 = c^2

36 + 49 = c^2

c^2 = 85

c = Square root of 85.

James needs to make a cut that is 18 inches long along the median to cut the tiles in half and create two congruent triangles. The correct answer is: D. 18 inches

To cut the tiles along the median, James needs to make a cut that divides the trapezoid into two congruent triangles. The median of a trapezoid is the line segment that connects the midpoints of the non-parallel bases.

In this case, the top base of the trapezoid is 15 inches, and the bottom base is 21 inches. To find the length of the median, we can take the average of the lengths of the top and bottom bases.

Median = (15 + 21) / 2

Median = 36 / 2

Median = 18 inches

The correct answer is: D. 18 inches

Let

x = the intended distance

y = length of the pool

She covers one fifth of her intended distance

Distance covered = 1/5 of x

= x/5

After swimming six more lengths of the pool she had covered one quarter of her intended distance

x/5 + 6y = 1/4 of x

x/5 + 6y = x/4

Collect like terms

6y = x/4 - x/5

6y = 5x - 4x/20

6y = x/20

x = 20 * 6y

= 120y

x = 120y

The intended distance Rebecca wants to cover = 120

A. The probability of getting 10 or more hits in a week is approximately 0.0131 using the Poisson distribution. B.The probability of getting 20 or more hits in 2 weeks is approximately 0.0175 using the Poisson distribution.

a. The probability that the site gets 10 or more hits in a week is approximately 0.0131.

To calculate this probability, we can use the Poisson distribution, which is commonly used to model the number of events that occur in a fixed interval of time when the events are rare and independent. In this case, the average number of hits per week is given as 5.

Let X be the random variable representing the number of hits in a week. The probability of getting 10 or more hits can be calculated as the complement of the probability of getting less than 10 hits.

Using the Poisson distribution formula, the probability mass function is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

Where λ is the average number of hits per week, and k is the desired number of hits.

To calculate the probability of getting less than 10 hits, we sum the probabilities for k = 0 to 9:

P(X < 10) = P(X = 0) + P(X = 1) + ... + P(X = 9)

Using the formula, we substitute λ = 5 and calculate the individual probabilities. Finally, we subtract this sum from 1 to find the probability of getting 10 or more hits:

P(X ≥ 10) = 1 - P(X < 10)

Evaluating this expression, we find that the probability is approximately 0.0131.

b. The probability that the site gets 20 or more hits in 2 weeks is approximately 0.0175.

To calculate this probability, we need to consider the number of hits over a two-week period. The average number of hits per week is still 5, so the average number of hits over two weeks is 10.

Let Y be the random variable representing the number of hits in two weeks. We can again use the Poisson distribution, but this time with λ = 10.

Similar to part a, we calculate the probability of getting less than 20 hits over two weeks:

P(Y < 20) = P(Y = 0) + P(Y = 1) + ... + P(Y = 19)

Using the Poisson distribution formula with λ = 10, we evaluate this sum. Finally, we subtract this sum from 1 to find the probability of getting 20 or more hits:

P(Y ≥ 20) = 1 - P(Y < 20)

Evaluating this expression, we find that the probability is approximately 0.0175.

The value for the functions (fg)(x) and (f/g)(x) are \(x^5 + 2x^4\) and \(\frac{x^4}{(x+2)}\) respectively.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To find (fg)(x), we simply need to multiply the two functions f(x) and g(x) -

(fg)(x) = f(x) × g(x)

\(= x^4 \times (x+2)\)

\(= x^5 + 2x^4\)

Therefore, (fg)(x) = \(x^5 + 2x^4\).

To find (f/g)(x), we divide the function f(x) by the function g(x) -

(f/g)(x) = f(x) / g(x)

= \(\frac{x^4}{(x+2)}\)

We cannot simplify this expression any further, so this is our final answer for (f/g)(x).

Therefore, (f/g)(x) = \(\frac{x^4}{(x+2)}\).

The Cox-Ross-Rubinstein (CRR) model is a mathematical model used in finance to evaluate the potential future value of an asset or portfolio. The model is based on the concept of a binomial tree.

A binomial tree is a mathematical model used in finance to estimate the probable future value of an asset or portfolio. The notion of a binomial, a mathematical expression with two potential outcomes, forms the foundation of the model. In a binomial tree, the future value of the asset is defined by two potential outcomes at each time step: a "upper" element and a down factor. The underlying variables that affect the asset, such as interest rates and market circumstances, dictate the up and down components. Reflecting This enables investors to assess the advantages and dangers of a possible investment and come to wise judgments.

Sampling without replacement is a process of collecting data from a population mean where each unit is selected only once.

To calculate sampling without replacement, first determine the size of the population you are sampling from. For example, if you are selecting 10 items from a population of 100, then the population size is 100. Next, calculate the number of possible combinations by using the mathematical formula nPr (n is population size, r is the number of items you are selecting). For our example, the formula would be 100P10, which would give us a result of 100!/(90!*10!) = 9,092,000 possible combinations. Finally, divide the number of possible combinations by the population size to determine the probability of selecting a specific combination. In our example, the probability would be 9,092,000/100 = 90,920.

The distance from the sun to the other focus is 5.01 × 10⁹ m.

(a) The distance from the center of an ellipse to a focus is an where a is the semi major axis and e is the eccentricity. Thus, the separation of the foci ( in the case of Earth's orbit ) is;

2ae = 2(1.50 × 10¹¹)(0.0167) = 5.01 × 10⁹ m.

(b) To express this in terms of solar radii, we set up a ratio;

1 =b

The y intercept is (0,1)

The equation of the line is y = -1/2x+1

Answer:the best predicted value of ý when the twin born first has an IQ of 109 is 107.50

Step-by-step explanation:

Given the regression equation:

ŷ = -2.59 + 1.01x

We need to predict the value of ý when x (IQ score of the twin born first) is 109.

So we substitute x = 109 into the regression equation:

ŷ = -2.59 + 1.01(109)

ŷ = -2.59 + 110.09

ŷ = 107.50

Therefore, the best predicted value of ý when the twin born first has an IQ of 109 is 107.50.
