Answer:

See below

Step-by-step explanation:

<u>Mercury-2.3 cm </u>   The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Venus - 4.3 cm</u>      The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Earth-6 cm</u>            There is no hundreths value so the tenths stays the same.

<u>Mars-9.1 cm</u>           The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Jupiter- 31.1 cm</u>      The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Saturn- 57.4 cm</u>     The hundreths value <u><em>is</em></u> greater than 5, so the tenths values is raised by 1.

<u>Uranus-114.9 cm </u>   The hundreths value isn't greater than 5, so the tenths stays the same.

Neptune-179.8 cm  There is no hundreths value so the tenths stays the same.

Answer:

i believe the answer to this is a total of 300 people because you multiply the ten percent into the 30 people which factors out some numerical values, so then your answer as i just said is 300 people in total attended the game.

tankabanditka [31]
<span>Arithmetic mean is used to describe the sum of values in a dataset divided by the number of values. It s the average of a given dataset which gives us an idea about the average value in a data set. That said, a mean of 4.3 means in the household sample (the average number of students in the data set falls within probably 4 and 4.7 probably). On the other hand,.a mean of 4.5 means there are more 8th graders than 7th graders. An increase of 0.2 from the 4.3 shows that the number of 8th graders slightly surpasses 7th graders. The principal can predict that there are more students in 8th grade because they have a higher average.</span>

Paha777 [63]

The equation that offers the best approximation to this result is: h = -16\cdot t^{2}+28\cdot t + 8. (Choice D)

<h3>How to find the free fall formula for a given scenario</h3>

An object experiments a free fall when it is solely accelerated by gravity on the assumption of an <em>uniform</em> acceleration. The formula is described below:

h =h_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g\cdot t^{2} (1)

Where:

  • h_{o} - Initial height, in feet.
  • v_{o} - Initial speed, in feet per second.
  • t - Time, in seconds.
  • g - Gravitational acceleration, in feet per square second.

If we know that t = 2\,s, h_{o} = 8\,ft, h = 0\,ft, g = -32.174\,\frac{ft}{s^{2}}, then the height formula is:

0 = 8 +2\cdot v_{o} - \frac{1}{2}\cdot (32.174)\cdot (2)^{2}

0 = -56.348+2\cdot v_{o}

v_{o} = 28.174\,\frac{ft}{s}

The equation that offers the best approximation to this result is: h = -16\cdot t^{2}+28\cdot t + 8. (Choice D)
