The equation of an ellipse is x²/a²  + y²/b² =1

a being the distance between the center & x intercept =7
b being the distance between the center & y intercept =5

Hence the equation of this ellipse is:

x²/49 + y²/25 =1

What is the volume of this rectangular
SashulF [63]
<h3>Given:</h3>
  • l= 5 meter
  • b= 4 meter
  • h= 3 meter
<h3>Note that:</h3>
  • l= length
  • b= breadth
  • h= height
<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

\large\boxed{Formula:V=\frac{1}{3}lbh}

First, multiply the length (5), breadth (4) and height (3).

5×4×3

= 60 \: cm

Now, divide 60 by 3.

\frac{60}{3}

\large\boxed{V= 20 \: {m}^{3}}

<u>Therefore,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>rectangular</u><u> </u><u>pyramid</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u><u>cubic</u><u> </u><u>meters</u><u>.</u>

Spinner goes 1-4. Jose spins the spinner 8 times. In those 8 spins, the arrow never lands on 3. Based on this information, shoul
Alenkinab [10]
Well this is a more complicated question than it may seem. The laws of probability are based on observations whose number is very large or actually as the number of observations approaches infinity. So on the one hand, you should be concerned that you get 0/8 to land on 3. However, 42/500 land on 3 so your ratio has improved. It's not near 125 but it's also not 0. If it remained at 0, you would begin to be concerned and rightly so. Perhaps if you did 5000, you would be less concerned as the ratio improved and got closer to 1/4 of the observations. So at this point I don't think you have enough information to determine that the spinner is unfair.

Leni [432]
Using the distance formula:- 

radius =  √ ( (8 - 2)^2 + (7 - -1)^2 )

           =  √ (6^2 + 8^2) = √100  = 10  (answer)
