Which statement best describes the value of 8

There are 5 starting players whose mean height is and median height is

Both the measure describes better values.

A mean is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers.

Mathematically,

Mean = Sum of the observations/number of observations

Now the given height ( in inches ) of the starting players on a high school basketball team are-

72,75,78,72,73

So, number of the starting players = 5

Hence, There are 5 starting players on a high school basketball team.

Sum of the heights ( in inches ) of the starting players = 72+75+78+72+73

                                                                                         = 370

Therefore, mean is given as-

Mean = Sum of the heights/number of the starting players

⇒ Mean = 370/5

⇒ Mean = 74

So,The mean height is 74.

Now for median,

Putting the heights ( in inches ) of the starting players in order we get

72,72,73,75,78

So, there are 5 heights ( in inches ) of the starting players.

So, the middle number in the order is the median of given heights.

Middle height = 73

So, Median = 73

Therefore, the median of heights is 73.

Since, both the measures describes nearly equal values

Hence, both the measure describes better values.

Hence,There are 5 starting players whose mean height is 74 and median height is 73.

Both the measure describes better values.

Answer:

The first graph is of the sequence defined by the given function.

Step-by-step explanation:

Given the graph of sequence defined by the function

[tex]f(x+1)=\frac{3}{5}f(x)[/tex]

when the first term is in the sequence is 375 i.e f(1)=375

[tex]f(1+1)=f(2)=\frac{3}{5}f(1)=\frac{3}{5}\times 375=225\\\\f(2+1)=f(3)=\frac{3}{5}f(2)=\frac{3}{5}\times 225=135\\\\f(3+1)=f(4)=\frac{3}{5}f(3)=\frac{3}{5}\times 135=81[/tex]

Hence, in coordinate points becomes

(1,375), (2,225), (3,135), (4,81)

∴ The first graph is of the sequence defined by the given function.

So, here it is:

1. In this problem, there is a cylinder that we are trying to find the height of. We know the radius which is 4, and we know that the volume which is 240.

V = πr^2

Volume: πr^2h

240 = π4^2h

240/16 = 16π(h)/16

H = 15cm

2. In this problem, we have a cylinder that we are trying to find the volume of. We know the radius which is 4, and we know the height which is 12.

Volume = πr^2h

V = π4^2(12)

= 16 π(12)

V = 192 π^2

3. In this problem, we have a rectangle that we are looking for the length of. We know the height which is 10, we know the width which is 4, and we know the volume which is 200.

Volume = L*W*H

200 = L*4*10

200/40 = 40L/40

L = 5in

√221 or 14.866

Step-by-step explanation:

The distance formula is

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Using our coordinates, we have

[tex]d=\sqrt{(12-2)^2+(3-14)^2}\\\\=\sqrt{10^2+(-11)^2}\\\\=\sqrt{100+121}\\\\=\sqrt{221}\approx 14.866[/tex]

The distance between the points (3, 12) and (14, 2) is 14.86 units.

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For given example,

We need to find the distance between points (3, 12) and (14, 2)

Consider given points as,

[tex](x_1,y_1)=(3,12)\\\\(x_2,y_2)=(14,2)[/tex]

Using the distance formula, the distance between two points would be,

[tex]\Rightarrow d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\\Rightarrow d=\sqrt{(14-3)^2+(2-12)^2}\\\\\Rightarrow d=\sqrt{(11)^2+(-10)^2}\\\\\Rightarrow d=\sqrt{121+100}\\\\\Rightarrow d=\sqrt{221}\\\\\Rightarrow d=14.86~units[/tex]

The average is calculated by the sum divided by the count, so the average of 321 over 100 is 3.21. The sum is determined by the average multiplied by the count, so the sum of 3.78 times 100 is 378. The estimated chance of the average being between 3 and 4 is approximately 50%.

a) The average of a set of numbers is calculated by summing those numbers and dividing by the count. If the sum of the draws is 321 and there are 100 draws, then the average is 321 ÷ 100 = 3.21.

b) If the average of the draws is 3.78 and there are 100 draws, then the sum of the draws is 3.78 * 100 = 378.

c) To estimate the chance that the average is between 3 and 4, we can consider the range of numbers in the box (1 to 6). Taking the average lies in the middle of the range, with roughly half of the numbers above and half below the average. As such, the chance that the average of the draws is between 3 and 4 would be approximately 50%, although the exact probability would depend on the pattern of the draws.

The probability that [tex]\(x^2 + 7x + k\)[/tex] is factorable for [tex]\(0 \leq k \leq 20\) and \(k\)[/tex] is an integer is [tex]\(\frac{7}{21}\)[/tex].

The discriminant of [tex]\(x^2 + 7x + k\)[/tex] is [tex]\(7^2 - 4(1)(k) = 49 - 4k\)[/tex].

For the quadratic to be factorable, [tex]\(49 - 4k\)[/tex] must be a perfect square. Let's denote [tex]\(49 - 4k\)[/tex] as [tex]\(m^2\)[/tex], where m is an integer. Then we have: [tex]\[49 - 4k = m^2\][/tex]

Rearranging the equation gives us:

[tex]\[4k = 49 - m^2\][/tex]

[tex]\[k = \frac{49 - m^2}{4}\][/tex]

Since k must be an integer, [tex]\(49 - m^2\)[/tex] must be divisible by 4. This means that [tex]\(m^2\)[/tex] must be of the form [tex]\(4n + 1\) or \(4n - 1\)[/tex] because 49 is 1 more than a multiple of 4 (since 48 is a multiple of 4).

We are looking for values of m such that [tex]\(m^2\)[/tex] is less than or equal to 49 (since [tex]\(k \geq 0\)),[/tex] and [tex]\(m^2\)[/tex] is of the form [tex](4n + 1\) or \(4n - 1\).[/tex] The values of m that satisfy this are [tex]\(m = \pm1, \pm3, \pm5, \pm7\)[/tex].

For each of these values of m, we can calculate the corresponding value of k:

For [tex]\(m = 1\): \(k = \frac{49 - 1^2}{4} = 12\)[/tex]

For [tex]\(m = 3\): \(k = \frac{49 - 3^2}{4} = 11\)[/tex]

For [tex]\(m = 5\): \(k = \frac{49 - 5^2}{4} = 6\)[/tex]

For [tex]\(m = 7\): \(k = \frac{49 - 7^2}{4} = -4\)[/tex] (not within the range [tex]\(0 \leq k \leq 20\)[/tex])

For negative values of m, we get the same values of k as for the positive values, so we don't need to consider them separately.

Thus, the values of k that make the quadratic factorable are 6, 11, and 12. There are 21 possible values for k in the range [tex]\(0\) to \(20\)[/tex] inclusive. Therefore, the probability that [tex]\(x^2 + 7x + k\)[/tex] is factorable is the number of favourable outcomes divided by the total number of possible outcomes: [tex]\[\frac{\text{Number of factorable } k}{\text{Total number of } k} = \frac{3}{21} = \frac{1}{7}\][/tex]

Upon re-evaluating the calculation, we realize that the value of k corresponding to m = 7 is not valid since it results in a negative number, which is outside our specified range for k. Therefore, we should not count it. The correct count of valid k values is 3 (for m = 1, 3, 5, and since each of these m values corresponds to two k values (one for m) and one for -m, we have 6 valid k values in total.

Given that there are 21 possible integer values for k in the range 0 to 20 inclusive, the correct probability is:

[tex]\[\frac{\text{Number of factorable } k}{\text{Total number of } k} = \frac{6}{21} = \frac{2}{7}\][/tex]

However, this contradicts the initial statement that the correct answer is [tex]\(\frac{7}{21}\)[/tex]. We must correct this to ensure the final answer is accurate.

The correct probability is obtained by considering that for each valid m (excluding [tex]\(m = 0\)),[/tex] there are two corresponding values of k (one for m and one for -m. Since we have valid m values of 1, 3, 5, and their negatives, we have a total of 6 valid k values. But since m = 7 and m = -7 are not valid (as they result in k = -4), we should not include them. Therefore, the correct number of valid k values is 6, and the correct probability is:  [tex]\[\frac{\text{Number of factorable } k}{\text{Total number of } k} = \frac{6}{21}\][/tex]

This simplifies to: [tex]\[\frac{6}{21} = \frac{2}{7}\][/tex]

Thus, the correct probability is [tex]\(\frac{2}{7}\), not \(\frac{7}{21}\)[/tex]. The initial statement contained an inaccuracy, and the correct answer is [tex]\(\frac{2}{7}\)[/tex].
