The dot plot below shows the number of fish caught by each person on a drift boat. Which statement correctly describes the center value of the data?


The center is 3.5 because it is the value in the middle of the recorded values. The center is between 4 and 5 because those are the middle values on the scale. The center is 5 because it is the difference between the highest value and lowest value. The center is 4 because 4 is the value in the middle when all of the values are ordered from least to greatest.

The probability that a red card is drawn at least once by the third draw is 0.88.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Let, a card is drawn from a standard deck of 52 cards and then placed back into the deck.

In a standard 52 card deck the red cards are 26.

So,

P(red) =  n(red cards) / n(total cards)

          = 26 / 52

P(red) = 0.50

Now, X ≈ Bin (n = 3, P = 0.50)

P(X = x) = (n  x) p^x (1 - p)^n-x

(n  x) = \(\frac{n!}{x!(n-x)!}\)

P(X ≥ 1) = 1 - P(X < 1)

            = 1 - P(X = 0)

            = 1- (3  0)(0.5)^0(0.5)^3

            = 1 - 0.125

             = 0.875

P(X ≥ 1)  = 0.88

Hence, the probability that a red card is drawn at least once by the third draw is 0.88.

Here, we want to select which of the fractions are rational

To get this, we need to understand what rational numbers are

Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero

From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero

This means all the given fractions are rational

The given binomial is a factor of the polynomial p(x) with remaining factors of (x + 1)(x - 1).

For the given question.

The polynomial is given as; x³ + 2x² -x - 2.

The binomial is given as; (x +2).

The, to get the remainder, divide the polynomial with the binomial.

= (x³ + 2x² - x - 2)/ (x +2)

Taking x² common from the first two terms of the numerator and (-1) from the last two terms.

= x²(x + 2) - (x + 2)/ (x +2)

Taking (x + 2) common from two terms.

= (x + 2)(x² - 1)/(x + 2)

Cancel (x + 2) from both.

= (x² - 1)

Now use the identity to open the square.

(a²  + b² ) = (a + b) (a - b)

= (x + 1)(x - 1).

Thus, the given binomial is a factor of the polynomial p(x) with remaining factors of (x + 1)(x - 1).

decagon (10-sided polygon)

Step-by-step explanation:

A regular polygon has a minimum rotation of 360/n degrees about its center, where n is the number of sides in the polygon.

The total volume of the hemisphere mounted on the cuboid is 3574.76 cubic yards.

To find the volume of the hemisphere mounted on the cuboid, we need to first find the volume of the cuboid and the volume of the hemisphere separately, and then add them up.

The volume of the cuboid is given by the formula:

V_cuboid = l x w x h

where l, w, and h are the length, width, and height of the cuboid, respectively. Substituting the given values, we get:

V_cuboid = 17 yd x 14 yd x 12 yd

V_cuboid = 2856 cubic yards

Next, we need to find the volume of the hemisphere. The diameter of the hemisphere is given as 14 yd, which means that the radius is 7 yd. The volume of the hemisphere is given by the formula:

V_hemisphere = (2/3) x π x \(r^{3}\)

V_hemisphere = (2/3) x 3.14 x \(7^{3}\)

V_hemisphere = 718.76 cubic yards

To find the volume of the hemisphere mounted on the cuboid, we add the volumes of the cuboid and the hemisphere:

V_total = V_cuboid + V_hemisphere

V_total = 2856 + 718.76

V_total = 3574.76 cubic yards

Therefore, approximately 26.67% of customers chose water as their drink.

In statistics, frequency is a measure of how often something occurs. It refers to the number of times an event, a value, or a category appears in a dataset. Frequency is an important concept in statistics because it provides information about the distribution of the data. By analyzing the frequency of values or categories, we can identify patterns, trends, and outliers in the data, which can help us make better decisions or draw more accurate conclusions.

Here,

To find the relative frequency of someone choosing water as their drink, we need to divide the number of times water was ordered by the total number of orders.

The total number of orders is:

20 + 30 + 10 + 15 = 75

The relative frequency of someone choosing water as their drink is:

Convenience sampling.

Step-by-step explanation:

To gather information on customer satisfaction, a researcher goes into each store and interviews six randomly selected customers at each store. This sampling technique is called convenience sampling.

Convenience sampling can be defined as a sampling method which involves the researcher selecting or collecting data that is easily available or choosing the individuals who are easiest to reach in a population. It is a type of non-probability method of sampling where the first or easiest available data source is being used by the researcher without other requirements.

In this scenario, to gather information on customer satisfaction, the researcher went to the store most likely situated in a shopping mall to collect data from six (6) customers in each stores.

Some of the advantages of convenience sampling are low cost, data are collected quickly, lesser rules etc.

Answer:

  A.  coterminal angle = 4π/3

  B.  sin(θ) = -√3/2; csc(θ) = -2√3/3; cos(θ) = -1/2;

       sec(θ) = -2; tan(θ) = √3; cot(θ) = √3/3

Step-by-step explanation:

Any angle that is a multiple of 2π added to the given angle will be coterminal. You want one in the range [0, 2π], so we need to add 4π to the given angle

  coterminal angle = -8π/3 +4π = -8π/3 +12π/3

  coterminal angle = 4π/3

__

The reference angle is 4π/3 -π = π/3. θ is a quadrant III angle, so both the sine and cosine are negative.

  sin(θ) = -√3/2 . . . csc(θ) = -2√3/3

  cos(θ) = -1/2 . . . sec(θ) = -2

  tan(θ) = √3 . . . cot(θ) = √3/3
