Answer:

$y = -\dfrac{4}{5}x + 11$

Step-by-step explanation:

(5, 7), (10, 3)

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{3 - 7}{10 - 5} = -\dfrac{4}{5}$

$y = mx + b$

$y = -\dfrac{4}{5}x + b$

$7 = -\dfrac{4}{5} \times 5 + b$

$7 = -4 + b$

$b = 11$

Answer:

$y = -\dfrac{4}{5}x + 11$

A coin is tossed times and comes up heads times. Use the Empirical Method to approximate the probability that the coin comes up

Vedmedyk [2.9K]

Answer:

$P(head) = 0.5600$

Step-by-step explanation:

Given

$n = 500$ -- number of toss

$head = 280$ --- outcomes of head

<em>See comment</em>

Required

Empirical probability of head

This is calculated as:

$P(head) = \frac{n(head)}{n}$

$P(head) = \frac{280}{500}$

$P(head) = 0.5600$

Solve by taking the square root of both sides.

horrorfan [7]

Answer:

Step-by-step explanation:

Given

3(x + 3)² - 81 = 0 ( add 81 to both sides )

3(x + 3)² = 81 ( divide both sides by 3 )

(x + 3)² = 27 ( take the square root of both sides )

x + 3 = ± $\sqrt{27}$ = ± 3 $\sqrt{3}$ ( subtract 3 from both sides )

x = - 3 ± 3 $\sqrt{3}$

x = - 3 - 3 $\sqrt{3}$ or x = - 3 + 3 $\sqrt{3}$ → a

0.250*140,000,000=35,000,000
40,000,000/35,000,000= 1.14

The area of the rectangle is 6 square feet. If its width is 2 1/7<br> feet, find its length.

densk [106]

Answer:

L = 2 4/5 feet

Step-by-step explanation:

A = L x W

6 = L x 2 1/7

divide both sides by 2 1/7

6 divided by 2 1/7 = L (is the same as multiplying by the reciprocal)

6 x 7/15 = L

L = 14/5 or 2 4/5
