The surface area of a triangular pyramid is 2304 cm2. If all the faces of the pyramid are congruent, what is the area of one fac

siniylev [52]

Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.

If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!

In two or more complete sentences, describe how to use technology to construct an appropriate regression model for the given dat

mamaluj [8]

The regression equation of the data values is y = 0.3x^2 - 2.8x +4.2

<h3>How to determine the regression equation?</h3>

Using a technology such as a graphing calculator, we simply input the data values in the graphing calculator and then wait for the result.

The x coordinates must be entered into the x values and the y coordinates must be entered into the y values

Using a graphing technology, the regression equation of the data values is y = 0.3x^2 - 2.8x +4.2

An article in the Journal of Engineering Tribology discusses several experiments involving various lubricants. In one experiment

MrRa [10]

Answer:

the P value is 45.22%

Step-by-step explanation:

The computation of the P value is as follows;

Given that

standard deviation = 14.9

mean = 675

Reduction in diameter= 673.2

Based on the above information,

We have to applied the following formula i.e.

$Z = \frac{x - \bar x}{\sigma} \\\\= \frac{673.2 - 675}{14.9}\\\\= -0.1208$

Now the P value for -0.1208 is 0.4522 i.e. 45.22%

Hence, the P value is 45.22%

The same is to be considered

Selena was comparing the flying speeds of different birds in science class. Which of the three birds flies fastest? Why?

Mashcka [7]

Answer:

Option C. The robin flies fastest because its rate is 15 m/s

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> the distance in meters

The speed is equal to divide the distance by the time

In this problem, the slope or unit rate of the linear equation is the same that the speed
