  a) 7/10

  b) 1/6

Step-by-step explanation:

a) There are 10 ways to roll a 5 or less. Of those, 7 are greater than 3.

(die 1)(die 2) ∈ {11, 12, 21, 13, 22, 31, 14, 23, 32, 41}

  p(>3 | ≤5) = 7/10

__

b) Of the 36 possible outcomes of rolling two dice, there are 6 ways to have a 6 and an odd number:

  {16, 36, 56, 61, 63, 65}

The probability of interest is 6/36 = 1/6.

Answer:

  • 84°
  • 125°

Step-by-step explanation:

<u>Sum of the interior angles of a regular polygon:</u>

  • S(n) = 180°(n - 2), where n- number of sides
<h3>Exercise 4</h3>

<u>Pentagon has sum of angles:</u>

  • S(5) = 180°(5 - 2) = 540°

<u>Sum the given angles and find x:</u>

  • x° + 122° + 100° + 90° + 144° = 540°
  • x° + 456° = 540°
  • x° = 540° - 456°
  • x° = 84°
<h3>Exercise 5</h3>

<u>Hexagon has sum of angles:</u>

  • S(6) = 180°(6 - 2) = 720°

<u>Sum the given angles and find x:</u>

  • x° + 110° + 160° + 105° + 105° + 115° = 720°
  • x° + 595° = 720°
  • x° = 720° - 595°
  • x° = 125°

The correct option is A.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient focuses on the linear relationship between two variables.

Given

The first column is labeled time spent at the dentist (in hours) with entries 1.4, 2.7, 0.75, 1.6.

The second column is labeled bill amount (in dollars) with entries 235, 867, 156, 215.

The numbers between -1 and 1 should be one of the values related to the bill.

Taking the independent variable or input variable as, the time a patient spends at the dentist and the dependent variable or output variable as the amount of the bill.

Hence, The correlation coefficient for the data in the table was found to be 0.93.

anastassius [24]

Answer:

y = -16.9

Step-by-step explanation:

<u>→Add 0.8y to both sides:</u>

-0.8y + 5.49 = -19.86 - 2.3y

5.49 = -19.86 - 1.5y

<u>→Add 19.86 to both sides:</u>

25.35 = -1.5y

<u>→Divide both sides by -1.5:</u>

-16.9 = y
