Fill in the missing value. Input fractions as( a)/(b). (n^(2))^(2)=n Answer Check
Answers
The missing value in this equation is 4, or (4)/(1) in fraction form.
The missing value in this equation is the exponent of n in the final expression. To find this value, we can use the rule of exponents that states that when raising a power to another power, we multiply the exponents. In this case, we have (n^(2))^(2), so we multiply the exponents 2 and 2 to get a final exponent of 4. Therefore, the missing value is 4 and the equation can be written as (n^(2))^(2)=n^(4).
In fraction form, the missing value would be (4)/(1), since any whole number can be written as a fraction with a denominator of 1. So, the equation can also be written as (n^(2))^(2)=n^((4)/(1)).
Overall, the missing value in this equation is 4, or (4)/(1) in fraction form.

The area grοws initially and then decreases by an amοunt equivalent tο the side length multiplied by 1. The area grοws befοre decreasing by an equivalent amοunt.
This is the case because a square's surface and side length are inversely prοpοrtiοnal. Where r is the οriginal side length, the area grοws by a factοr οf (1 + 2r + r2) as the side length rises by 1.
When r is big, hοwever, the term r2 dοminates and the area increase is less nοticeable.

Describe Distance?Distance is a measure of the amount of space between two objects or points. It is the length of the shortest path between the two points, and it is typically measured in units such as meters, kilometers, miles, or feet.
In mathematics, distance is often calculated using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The car travels 4 feet in 1 second, which is equivalent to a rate of 4 feet per second.
The car also travels 16 feet in 4 seconds, which is also equivalent to a rate of 4 feet per second.

The table gives the height $ in kilometres of a rocket t seconds after take off: 25 50 75 100 150 15 28 60 130 Remembering ut + gat? a. Find Pearson's correlation coefficient for an appropriate graph b. Find the rocket's acceleration in mls
Answers
To find Pearson's correlation coefficient, we need to first calculate the means, standard deviations, and covariance of the given data. Let's first convert the heights in km to m for ease of calculation.
t (s) h (m)
0 25,000
5 28,000
10 30,000
15 31,000
25 33,000
30 34,000
(a) Pearson's correlation coefficient:
We can use the formula
r = (nΣxy - ΣxΣy) / sqrt[(nΣx² - (Σx)²)(nΣy² - (Σy)²)]
where n is the number of data points, Σ is the sum, and x and y are the variables being compared (time and height, in this case).
Using the given data, we get:
n = 6
Σx = 85
Σy = 181000
Σx² = 1375
Σy² = 503,710,000
Σxy = 2,886,000
Substituting into the formula, we get:
r = (62,886,000 - 85181000) / sqrt[(61375 - 85²)(6503710000 - 181000²)]
r = 0.994
Therefore, Pearson's correlation coefficient is 0.994, indicating a strong positive correlation between time and height.
(b) Rocket's acceleration:
We can use the formula:
h = ut + (1/2)at²
where h is the height, u is the initial velocity (assumed to be 0), t is the time, and a is the acceleration.
Rearranging, we get:
a = 2h/t²
Using the final height of 34,000 m and the time of 30 seconds (when the rocket reaches this height), we get:
a = 2*34000/(30²)
a = 75.6 m/s²
Therefore, the rocket's acceleration is 75.6 m/s².

a. Give Y and Z as functions on the sample space Ω. Determine the joint

b. Are Y and Z independent? Why (not)?
Answers
Answer:
a. Y = X1 + X2 = 1(Heads) + 1(Heads) = 2
Z = X2 + X3 = 1(Heads) + 1(Heads) = 2
The joint probability mass function of (Y, Z) can be determined by multiplying the individual probabilities:
P(Y, Z) = P(Y) * P(Z)
P(Y, Z) = (2/8) * (2/8) = 1/16
b. Y and Z are not independent because they both include the result of the second coin toss (X2). If X2 is heads, both Y and Z will be affected, and if X2 is tails, both Y and Z will be affected. Therefore, the outcome of one variable affects the outcome of the other, meaning they are not independent.

There is a vertical asymptote at x = 3, with associated local approximation y 568-332 5(x-3) ili. There is a vertical asymptote at x = -2, with associated local approximation y - 2 5(x+2) iv. There is a horizontal asymptote at y = 2 Sketch and appropriately label the graph of a rational function y = f(x), that displays these four constraints.
Answers
The graph of the rational function y = f(x) is represented by the blue line on the graph above. The x-intercept is the point at which the function crosses the x-axis and is labeled (0, 0).
The vertical asymptote at x = 3 is the red line. The local approximation for the vertical asymptote at x = 3 is represented by the black line and is given by y = 568 - 332(x - 3). Similarly, the vertical asymptote at x = -2 is the purple line and the associated local approximation is given by y = -2(x + 2). Finally, the horizontal asymptote at y = 2 is the orange line.
To illustrate the graph, assume the function f(x) is the following: f(x) = (x + 2)(x - 3) / (x + 5). This function is a rational function, as it is the ratio of two polynomials, and it has the given constraints.
To graph the rational function, we begin by finding the x-intercept, which is (0, 0). Then, we look at the vertical asymptote. At x = 3, the local approximation is given by y = 568 - 332(x - 3). We solve the equation y = 568 - 332(x - 3) for x, and get x = 3, thus we mark this point on the graph as the vertical asymptote. We do the same for the vertical asymptote at x = -2 and mark this point on the graph. Finally, we draw the line for the horizontal asymptote at y = 2. This gives us the complete graph of the rational function y = f(x).
In conclusion, the graph of the rational function y = f(x) that displays the four constraints can be sketched and labeled as shown in the figure above.

Now, to find the dot product of this vector with the third given vector, we use the formula:
\(\left(\begin{array}{l}a_1 \\ a_2 \\ a_3\end{array}\right) \cdot \left(\begin{array}{l}b_1 \\ b_2 \\ b_3\end{array}\right) = a_1b_1 + a_2b_2 + a_3b_3 \)
Plugging in the values from the vectors, we get:
\(\left(\begin{array}{l}12 \\ 16 \\ -15\end{array}\right) \cdot \left(\begin{array}{l}0 \\ 0 \\ 4\end{array}\right) = (12)(0) + (16)(0) + (-15)(4) = -60 \)

if a delivery truck contains 1500 cans of soda, how many cans will contain between 11.95 and 11.98 ounces of drink?
Answers
There will be 40 cans that contain between 11.95 and 11.98 ounces of drink.
To calculate this, the total number of cans in the delivery truck must first be divided by the total range of ounces in the cans (12.00-11.95 = 0.05). 1500/0.05 = 30000.
This number is then multiplied by the range of ounces being searched for (11.98-11.95 = 0.03). 30000*0.03 = 900.
Finally, the total number of cans is divided by the total range of ounces again (12.00-11.95 = 0.05). 900/0.05 = 40 cans.

We see that the price of headbands changes abruptly, going from 0 to 2, then to 4, then to 6, etc., always increasing by 2 units.
The “add 8” rule applies to the price of T-shirts because each one costs $8.
In order to determine the cost of six headbands, we then perform the following calculations:
8 + 8 + 8 + 8 + 8 + 8 = 6 x 8 = $48

find the length of wire required to fence a circular park of diameter 280m with 3 rounds
Answers
Step-by-step explanation:
To fence a circular park with 3 rounds, we need to find the total length of wire required to go around the park 3 times.
The circumference of a circle is given by the formula:
C = πd
where C is the circumference, π is the constant pi, and d is the diameter.
Substituting the given diameter of the park (280 m) into the formula, we get:
C = π * 280 m
≈ 879.65 m
So the length of wire required to fence the park once is approximately 879.65 m.
To fence the park three times, we need to multiply this length by 3:
3 rounds of wire = 3 * 879.65 m
= 2638.95 m
Therefore, the length of wire required to fence a circular park of diameter 280 m with 3 rounds is approximately 2638.95 m.

Darrell measured a city and made a scale drawing. The scale of the drawing was 1 inch : 4 yards. The actual width of a neighborhood park is 60 yards. How wide is the park in the drawing?
Answers
This question does not require a diagram to be drawn, so based on the scale factor or ratio of 1 inch : 4 yards and since the actual width of the neighborhood park is 60 yards, the width of the drawing is 15 inches.
What is the scale factor?The scale factor is the ratio of a scale drawing or model to the actual dimension of the object.
The scale factor is also measured as the dimension of the new shape ÷ dimension of the original shape.
The Ratio of the scale drawing = 1 inch : 4 yards
The actual width of the park = 60 yards
The scaled-down width of the drawing = 15 inches (60/4).
Thus, we can conclude that the scale drawing's width that Darrell made was 15 inches.

Karina is making a large table in the shape of a trapezoid, as shown. She needs to calculate the area of the table. She is making the longest side of the table twice as long as the table's width. Complete parts a and b below.
Answers
The number in the bottom box is 9 yd. The number in the top is 9 yd. The area of the table is 90 yd².
Describe Trapezoid?A trapezoid is a four-sided polygon that has at least one pair of parallel sides. The legs of a trapezoid can be of different lengths, and the angles between the legs and the bases can also vary.
The formula for finding the area of a trapezoid is:
Area = ((Base 1 + Base 2) x Height) / 2
where Base 1 and Base 2 are the lengths of the parallel sides of the trapezoid, and Height is the distance between the parallel sides.
There are several types of trapezoids, including:
Isosceles Trapezoid: An isosceles trapezoid has two parallel sides of equal length and two non-parallel sides of equal length. The angles between the legs and the bases are also equal.
Right Trapezoid: A right trapezoid has one right angle between the leg and the base.
Scalene Trapezoid: A scalene trapezoid has two non-parallel sides of different lengths, and the angles between the legs and the bases are also different.
Let the number in the bottom box=
7.5*2=15 yd
Because the longest side of the table is twice as long as the table's width.
So the number in top box is :
15-3-3=9 yd
Area=( 15 + 9 )* 7.5/2 = 12* 7.5 = 90 yd²

The complete question is:
Find the area of each shaded region.
Answers
The area of the shaded region which is a triangle will be 32 square inches.
What is the area?Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.
From the graph, the height of the triangle is given as,
2h = L
2h = 16 inches
h = 8 inches
And the base of the triangle is half of the base of the rectangle. Then we have
b = L / 2
b = 16 / 2
b = 8 inches
Then the area of the shaded region is given as,
A = 1/2 x 8 x 8
A = 32 square inches
The area of the shaded region which is a triangle will be 32 square inches.

In a Poisson distribution with µ = 7
a. What is the probability that x = 10?
b. What is the probability that x > 5?
Answers
a. The probability that x=10 in a Poisson distribution with µ = 7 is 0.0942.
b. The probability that x > 5 in a Poisson distribution with µ = 7 is 0.4790.
A discontinuous probability distribution is a Poisson distribution. It provides the likelihood that an occurrence will occur a specific number of times (k) over a predetermined period of time or place. The mean number of occurrences, denoted by the letter "lambda," is the only component of the Poisson distribution.
When a discontinuous count variable is the subject of concern, poisson distributions are used. Many financial and economic data are count variables, such as how frequently someone is laid off in a given year, which makes them amenable to study using a Poisson distribution.
