Answer:

27.55

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms.

So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4

220.4 / 8 = 27.55

5. Write an equation for the line that is parallel to the given line and that passes through the given point. y = –5x + 3; (–6,
Naily [24]

Answer:

y = -5x - 27

Step-by-step explanation:

First and foremost, parallel lines have SIMILAR <em>RATE</em><em> </em>OF <em>CHANGES</em> [<em>SLOPES</em>],<em> </em>so we keep the -5. Moving forward, we simply plug the coordinate into the Slope-Intercept Formula, <em>y</em><em> </em><em>=</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>b</em><em> </em><em>-</em><em>-</em><em>></em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>-</em><em>5</em><em>[</em><em>-</em><em>6</em><em>]</em><em> </em><em>+</em><em> </em><em>b</em><em>.</em><em> </em>Our y-intercept is [0, -27], therefore our parallel equation is <em>y</em><em> </em><em>=</em><em> </em><em>-</em><em>5x</em><em> </em><em>-</em><em> </em><em>27</em><em>.</em>

The weight of an object on Earth varies directly as the weight of the same object on the moon. A 300 pound object on Earth would
slava [35]

Answer: 12 pounds.

Step-by-step explanation:

To solve this question, we'll use the direct proportion which is.

y = kx

Where,

y = weight on moon = 48 pounds

x = weight on Earth = 300 pounds

k = Unknown

y = kx

48 = 300k

k = 48/300

k = 0.16

The weight that a 75 pound object on Earth would weigh on the moon will be:

y = kx

where,

y = weight on moon = Unknown

k = 0.16

x = weight on Earth = 75 pounds

y = kx

y= 0.16 × 75

y = 12 pounds

The weight on the moon will be 12 pounds.
