The best guess for how many times you will choose a blue marble out of 12 trials is 8 times.

The likelihood of choosing a blue marble on each trial stays constant over the course of the 12 trials if there are 3 marbles total—2 blue and 1 green—and you choose one without looking.

The likelihood of selecting a blue marble on any given trial is 2/3, or 2 out of 3.

You may multiply the likelihood of selecting a blue marble on each trial by the number of trials to determine how many times you will choose a blue marble over the course of 12 trials:

E = Probability of blue marble * Number of trials

E = (2/3) * 12

The five-number summary, as shown in the MINITAB output, includes the minimum value, Q1 (the first quartile), the median (Q2), Q3 (the third quartile), and the maximum value.

To calculate the interquartile range (IQR), we need to find the difference between Q3 and Q1. In this case, Q1 is 6 and Q3 is 11, so the IQR is 5.
To determine if there are any outliers in the data set, we can use the rule that any data points that are more than 1.5 times the IQR below Q1 or above Q3 are considered outliers. In this case, the lower limit would be 6 - (1.5 x 5) = -1.5 and the upper limit would be 11 + (1.5 x 5) = 18.5. Looking at the data in column 1, we can see that there are no values that fall outside of these limits, so there are no outliers in this set of data.
Using statistics software to calculate the five-number summary, IQR, and identify outliers is a quick and efficient way to analyze data. This information can provide valuable insights into the distribution of the data and help identify any potential issues or trends that need to be addressed.

Answer:

  4.49352×10¹²

Step-by-step explanation:

You want the product of 5.688×10⁹ and 7.9×10² expressed in scientific notation.

Generally, we use a calculator to simplify multiplication of such numbers. We can ask that same calculator to display the results in scientific notation. The number of significant digits in the product will be the sum of the numbers of significant digits in the given coefficients: 4 + 2 = 6.

  5.688×10⁹ · 7.9×10² = 4.49352×10¹²

__

Additional comments

A spreadsheet also gives you the option of displaying the number in scientific notation.

Note that many calculators use an "E" notation for entering the exponent of numbers in scientific notation. The key used for entering the exponent may be labeled EEX or EE or EXP. Some also use that same E notation for displaying the result.

The number of significant digits in the product that are of interest depends on the application. We have given the result of straight multiplication of these numbers. In a measurement or physics application, the result should be rounded to 2 significant digits, the number of digits in the least-precise factor. For general engineering application, you may want to round to about 4 significant digits, as more precision than that is often unneeded. If this is a value that will be added or subtracted with another, you probably want to keep the full precision available.

The ball hits the ground after a time of 3.05 seconds.

The quadratic function giving the ball's height after t seconds is given as follows:

h(t) = -16.1t² + 150.

(In which -16.1 is the gravity's effect, while 150 is the initial height).

The ball hits the ground when the height function has a numeric value of zero, that is:

h(t) = 0.

Hence the time is obtained solving the equation, isolating the variable t, as follows:

-16.1t² + 150 = 0

16.1t² = 150

t² = 150/16.1

[tex]t = \sqrt{\frac{150}{16.1}}[/tex]

The area of the triangle T with sides u = ⟨3, 3, 3⟩, v = ⟨6, 0, 6⟩, and u-v is 9√3 square units.

To find the area of the triangle T, we first calculate the cross product of vectors u and v, denoted as u × v. The magnitude of the cross product gives us the area of the corresponding parallelogram, and dividing it by 2 gives us the area of the triangle.

Calculating the cross product:

u × v = |i j k|

|3 3 3|

|6 0 6|

Expanding the determinant:

u × v = (36 - 30)i - (36 - 36)j + (30 - 36)k

= 18i - 0j - 18k

= 18(1, 0, -1)

The magnitude of the cross product:

|u × v| = |18(1, 0, -1)|

= 18|1, 0, -1|

= 18√(1² + 0² + (-1)²)

= 18√2

= 18√3 square units.

Therefore, the area of triangle T is half the area of the parallelogram, which is (1/2)(18√3) = 9√3 square units.

Step-by-step explanation:

To calculate the surface area of an A-frame tent with a rectangular floor, you need to find the area of each of its three faces: the front, the back, and the roof.Assuming that the A-frame tent has a symmetrical design, the front and the back will be identical triangles with a base of 6 feet and a height of 4 feet. To find the area of one of these triangles, you can use the formula for the area of a triangle: A = 1/2 * base * height. Therefore, the area of one of the triangular faces is:A_front/back = 1/2 * 6 ft * 4 ft = 12 ft²The roof of the A-frame tent is also a triangle, but with a base of 9 feet and a height that is half of the tent's height (since the tent is symmetrical). So, the height of the roof triangle is 2 feet, and its area is:A_roof = 1/2 * 9 ft * 2 ft = 9 ft²To find the total surface area of the tent, you simply need to add up the areas of the three faces:Total surface area = 2 * A_front/back + A_roof

= 2 * 12 ft² + 9 ft²

= 33 ft²Therefore, you would need at least 33 square feet of canvas to make the A-frame tent described.

The series ∑(-5)^n/(n^2) is convergent.

The ratio test is a method for determining whether an infinite series converges or diverges. It involves taking the limit of the absolute value of the ratio of successive terms:

lim n→∞ |an+1/an|

If this limit is less than 1, then the series converges. If it is greater than 1, then the series diverges. If it is exactly equal to 1, then the test is inconclusive and another method must be used.

For the series ∑(-5)^n/(n^2), we have:

|a(n+1)/an| = |-5|^(n+1)/(n+1)^2 * n^2/(-5)^n

Simplifying this expression gives:

|a(n+1)/an| = (25(n^2))/((n+1)^2)

Taking the limit as n approaches infinity gives:

lim n→∞ |a(n+1)/an| = 25

Since the limit is greater than 1, the series diverges by the ratio test.

Therefore, we conclude that the series ∑(-5)^n/(n^2) is convergent.

The probability that the child will catch 10 or more balls in 20 attempts, assuming a 0.2 probability of catching a ball on any single attempt, is very small, approximately 0.00014.

The probability that the child will catch 10 or more balls can be calculated using the binomial distribution.

Let X be the number of balls caught by the child in a total of 20 attempts. The probability of catching a ball on any single attempt is p = 0.2, assuming that each attempt is independent of the others.

The probability of catching exactly k balls in 20 attempts is given by the binomial distribution formula:

P(X = k) = (20 choose k) * p^k * (1-p)^(20-k)

where (20 choose k) is the binomial coefficient, which is equal to 20!/(k!(20-k)!).

The probability of catching 10 or more balls can be calculated as the sum of the probabilities of catching 10, 11, 12, ..., 20 balls:

P(X ≥ 10) = P(X = 10) + P(X = 11) + ... + P(X = 20)

Using a calculator or computer software, this probability can be found to be approximately 0.00014 (rounded to five decimal places).

Therefore, the probability that the child will catch 10 or more balls in 20 attempts, assuming a 0.2 probability of catching a ball on any single attempt, is very small, approximately 0.00014.

The two points at which the line intersects the curve are (2, -2) and (4/3, -4).

To find the coordinates of the point at which the line with a gradient of 3 intersects the curve y = 3x² - 7x after passing through the point (2, -2), we can set the equation of the line equal to the equation of the curve and solve for x and y.

The equation of the line passing through (2, -2) with a gradient of 3 can be written as:

y = 3x - 8

Substituting this equation into the curve equation, we get:

3x - 8 = 3x² - 7x

Simplifying the equation:

3x² - 10x + 8 = 0

We can solve this quadratic equation to find the values of x. Using factoring or the quadratic formula, we find:

(x - 2)(3x - 4) = 0.

Setting each factor equal to zero:

x - 2 = 0 --> x = 2

3x - 4 = 0 --> x = 4/3

So, there are two possible x-values where the line can intersect the curve: x = 2 and x = 4/3.

Now, we can substitute these x-values back into the equation of the line to find the corresponding y-values:

For x = 2:

y = 3(2) - 8 = 6 - 8 = -2

For x = 4/3:

y = 3(4/3) - 8 = 4 - 8 = -4

Therefore, the probability of drawing a green card is 0.0769 or 7.69%.

a. To determine the number of elements in the sample space, we need to know the number of cards in the deck and the possible outcomes for each card. Let's assume that the deck contains 52 cards with four different suits (clubs, diamonds, hearts, spades) and 13 cards in each suit (ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king).

The possible outcomes for each card are the suit and the rank. Therefore, there are 4 possible outcomes for the suit and 13 possible outcomes for the rank. Using the multiplication principle, we can determine the number of elements in the sample space by multiplying the number of possible outcomes for the suit by the number of possible outcomes for the rank:

Number of elements in the sample space = 4 x 13 = 52

Therefore, there are 52 elements in the sample space.

b. To find the probability of drawing a green card, we need to know how many green cards there are in the deck and how many cards there are in total. Let's assume that there are 4 different colors of cards in the deck: red, blue, yellow, and green. We also assume that there are 13 cards of each color in the deck.

Therefore, there are 4 green cards in the deck. The probability of drawing a green card can be calculated by dividing the number of green cards by the total number of cards in the deck:

Probability of drawing a green card = number of green cards / total number of cards

Probability of drawing a green card = 4 / 52

Probability of drawing a green card = 0.0769 or 7.69%

Therefore, the probability of drawing a green card is 0.0769 or 7.69%.
