Answer:

8 9.8 - 6.4n

9 15 - j/2

Step-by-step explanation:

2.8 - 4.4n - 2n +7

= 2.8+7 -4.4n -2n

= 9.8 - 6.4n

11 + (-3) - 1/8 j - 3/8 j +7

= 11 - 3 - 1/8 j - 3/8 j + 7

= 11 - 3 + 7 - 1/8 j - 3/8 j

= 15 - 4/8 j

= 15 - j/2

Answer:

125

Step-by-step explanation:

The total number of marbles is 6+10 = 16

P (black) = black / total

= 10/16 = 5/8

With 200 draws, take the probability of P(black) times 200 since the marble is returned each time

200 * (5/8) = 125

We would expect to get 125 black marbles

The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let F represent temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

At 0°C, the temperature is 32°F. Also at 100°C, the temperature is 212°F, hence:

$C-0=\frac{100-0}{212-32} (F-32)\\\\C=\frac{5}{9} (F-32)$

The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)
