They surveyed a random sample of 13 players and asked how long it took them (in minutes). 1.235 952 457 1,486 1,486 | 1,759 1,148 548 1,0371,864 | 1,245 866 1,431 a. Estimate the median time it will take all players to finish this game. minutes b. Find the interquartile range for this sample minutes

Answers

Answer 1

Answer:

a) median = 1,148 minutes

b) IQR = 549.5

Step-by-step explanation:

Q1 = (952 + 866) / 2 = 909

Q3 = (1431 + 1486) / 2 = 1458.5

IQR = 1458.5 - 909.0 = 549.5

x = A 21.6 B 12.9 C 9.1

Answers

Answer:

B: 12.9

Step-by-step explanation:

If A B and C are the alternatives, the answer is B: 12.9

The reason is that the hypotenuse can't be smaller than one of its sides, that eliminates alternative C.

And also, the hypotenuse can't be bigger than segments AC + BC, since the side AC is bigger and AC measures 10.8, the hypotenuse would have to measure < 21.6

Any questions, comment.

Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

sin57° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )

x × sin57° = 12 ( divide both sides by sin57° )

x = [tex]\frac{12}{sin57}[/tex] ≈ 12.9 ( to 1 dec. place ) → B

How do I find the 15th term of this problem?

Answers

Answer:

130

Step-by-step explanation:

Given,

AP : 18, 26, 34, ...

To find : 15th term

15th term is t15.

AP : 18, 26, 34, ...

Here,

a = 18

d = 26 - 18 = 8

Formula : -

an = a + ( n - 1 )d

t15

= 18 + ( 15 - 1 )8

= 18 + 14 ( 8 )

= 18 + 112

= 130

Therefore, the 15th term is 130.

What is an expression? What is a triangle?A mathematical expression is a combination of terms separated by mathematical operators. For example : 2x + 3y + 6. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.

We have two triangles as shown in the image.

The coordinates of a triangle ABC are shifted 6 units downward and then the complete figure is reflected across the y - axis.

Therefore, the transformation given in option [1] is the correct transformation that maps ABC to DEF.

He tests this by spinning 101010 different pennies 101010 times each, so he's willing to treat these spins as a random sample. In his 100100100 spins, the penny landed showing "heads" in 686868 spins. He wants to use these results to test H_0: p=0.50H

Step-by-step explanation:

Vertical angles can be defined as the pair of angle which are opposite when two lines crosses, as the image attached shows.

Now, <EYL and <AYS are vertical angles, because they are opposite when lines ES and AL cross at point Y.

Another pair of vertical angles are <SYL and <EYA, because they are opposite when lines ES and AL cross at point Y.

Therefore, all pair of angles which are vertical angles are

f(-1) is undefined.

Step-by-step explanation:

We are given:

[tex]f(x) = \left\{ \begin{array}{ll} -3x-11 & \quad x \leq -5\\ 2 & \quad x > 5 \end{array} \right.[/tex]

And we want to find f(-1).

The piecewise function only gives us values for x-values less than or equal to -5 or greater than 5.

Since -1 is fits neither of those conditions, it is not defined.

Our answer is undefined.

You are constructing a 95% confidence interval using the information: n = 60, x-bar = 65.5, s = 2.5, and E = 0.70. What is the value in the middle of the interval?

Answers

Answer:

65.5

Step-by-step explanation:

Using the relation :

Xbar ± Margin of error

Margin of Error = Zcritical * s/√n

The Zcritical value at 95% = 1.96

Hence,

Margin of Error = 1.96 * 2.5/√60

Margin of Error = 1.96 * 0.3227486

Margin of Error = 0.6326

Lower boundary = 65.5 - 0.6326 = 64.867

Upper boundary = 65.5 + 0.6326 = 66.133

(64.867 + 66.133) / 2

Find the formula for the following sequence

Geometric : a7=9 and a12=2187

Answers

Step-by-step explanation:

a geometric sequence is s sequence, where every new element is generated by multiplying the previous element by the same number.

a n = a1 × number^(n-1)

so, a12/a7 = number^5

=> 2187/9 = 243 = number^5

[tex]number = \sqrt[5]{243} [/tex]

=> number = 3

so, what is a1 ?

it has to satisfy e.g. a7.

9 = a1 × 3^6

9 = 3^2

=> 3^2 = a1 × 3^6

=> 1 = a1 × 3^4

=> a1 = 1/(3^4) = 1/81

therefore, the whole formula is

a n = 1/81 × 3^(n-1 )
