Here, ∠1 and ∠2 are complementary angles which means they together are forming a right angle or we can also say that their sum is 90°.So, According to this:

\sf∠1 + ∠2 = 90

  • ∠1 = x-8
  • ∠2 = 6x

\sf \: x - 8 + 6x = 90

\sf \: 7x - 8 = 90

\sf \: 7x = 90 + 8

\sf \: 7x = 98

\sf \: x = 14

<h3>Now, </h3>

  • \tt∠1 = x - 8 \\  \tt = 14 - 8 \\  \tt = 6
  • \tt \: ∠2 = 6x \\  \tt = 6 \times 14 \\  \tt = 84

<em>Thus, The measure of m∠1 is 6° and measure of m∠2 is 84°...~</em>

Suppose a six-sided die is tossed 1200 times and a 6 comes up 419 times. (a) Find the empirical probability for a 6 to occur. (E
krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

         =\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349

Probability = 0.349

b) Theoretical Probability:

                     =\frac{1}{6}

Here both probabilities are not equal.

Therefore the die is not fair and biased.

e-lub [12.9K]

Answer:

y - 7 = 16/13(x - 7)

General Formulas and Concepts:

<u>Alg I</u>

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-6, -9)

Point (7, 7)

<u>Step 2: Find slope </u><u><em>m</em></u>

  1. Substitute:                   m=\frac{7+9}{7+6}
  2. Add:                             m=\frac{16}{13}

<u>Step 3: Write equation</u>

y - 7 = 16/13(x - 7)

1/5( 5/2 x 4/7 -11/7) + 3/28

Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.

Then multiply 1/5 with 10/7. The result will be 2/7.

2/7 + 3/28 = 11/28
