An avid golf fan recorded the scores of 75 golfers on the ninth hole of the Cottonwood Golf Course as follows :

Vadim26 [7]

Answer:

<u>The correct answer is 3.77 strokes as the average score for the ninth hole of the Cottonwood Golf Course.</u>

Step-by-step explanation:

1. To find the average score, we need to know how many strokes the 75 golfers needed to play this ninth hole. For doing that, we will do the following addition, using the frequency data given:

1 x 1 = 1

1 x 2 = 2

32 x 3 = 96

27 x 4 = 108

8 x 5 = 40

6 x 6 = 36

1 + 2 + 96 + 108 + 40 + 36

<u>283</u>

<u>This means that all the 75 golfers scored 283 strokes for playing the ninth hole</u>

2. Now that we know that the total number of strokes was 283, we will do a division for find the average score, using also the number of golfers. For doing it, we will do the following division:

Total number of strokes/ total number of players

<u>283/75 = 3.77</u>

<u>The average score is 3.77. It means that the 75 golfers in average hit 3.77 strokes to play the ninth hole.</u>

Find the smallest positive integer k such that 3240/k is a square number

sashaice [31]

Answer:

10

Step-by-step explanation:

First, factorize the number 3,240:

$3,240=2\cdot 1,620=2\cdot 2\cdot 810=2\cdot 2\cdot 2\cdot 405=2\cdot 2\cdot 2\cdot 2\cdot 5\cdot 81=2^3\cdot 5\cdot 9^2$

So,

$3,240=2^2 \cdot 2\cdot 5\cdot 9^2=18^2\cdot 10$

Now consider the fraction

$\dfrac{3,240}{k}=\dfrac{18^2\cdot 10}{k}$

If k = 10, then

$\dfrac{3,240}{k}=\dfrac{18^2\cdot 10}{10}=18^2$

is a square number.

For all k < 10, the fraction tex]\dfrac{3,240}{k}[/tex] is not a square number (this follows from factorization).

Or you can simply check the values of the fraction for all k < 10:

k = 1, $\dfrac{3,240}{1}=3,240$ is not a square number;
k = 2, $\dfrac{3,240}{2}=1,620$ is not a square number;
k = 3, $\dfrac{3,240}{3}=1,080$ is not a square number;
k = 4, $\dfrac{3,240}{4}=810$ is not a square number;
k = 5, $\dfrac{3,240}{5}=648$ is not a square number;
k = 6, $\dfrac{3,240}{6}=540$ is not a square number;
k = 7, $\dfrac{3,240}{7}$ is not a square number;
k = 8, $\dfrac{3,240}{8}=405$ is not a square number;
k = 9, $\dfrac{3,240}{9}=360$ is not a square number.

Determine whether each number is rational or irrational.

kirill115 [55]

Answer:

where is the question.

So basically rational numbers are numbers with decimals that are not random

ex) 3.66666666, 4.040404040, 3.5645645645646

the decimals are at a fixed order

Irrational is random decimals that makes it look weird

ex)3.141592643, 5. 782759453, 8.825928342

hope that answers your question
