What would a line look like on a cone? on a sphere? on a box? on a hyperboloid

yanalaym [24]

A line can take different shapes depending on the geometric figure or prism it is representing.

<h3>How would you describe a line on a cone?</h3>

A cone is a solid figure that arises as a result of the revolution or rotation of a right triangle taking its leg as its axis. According to the above, a line in a cone can be seen as straight from the tip of the cone to its base.

<h3>How would you describe a line on a sphere?</h3>

A sphere is a solid figure that arises as a result of the revolution or rotation of a circle about its own center. A line on a sphere can be seen to be circular as if a cut were made in any plane of the sphere.

<h3>How would you describe a line in a box?</h3>

A box is a solid figure that arises as a result of the projections of a rectangle in three dimensions. A line in a box can be seen as either side, a straight line that is at 90° angles to two others.

<h3>How would you describe a line in a hyperboloid figure?</h3>

A hyperboloid figure is a solid figure that arises as a result of the revolution or rotation of a hyperbola. A line in a hyperboloid can take the curved shape of any of its sides.

Which of the following is a Type I error?

Sedaia [141]

Answer:

C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398.

Step-by-step explanation:

A type I error occurs if you reject the null hypothesis when it is true.

Now the hypotheses are:

$H_0:$ The proportion is 0.398

$H_1:$ The proportion is less than 0.398

If in actual fact the proportion is 0.398, then the president must not reject the $H_0$ .

This is a correct decision.

If in actual fact the proportion is 0.398, and the president rejects the $H_0$ , then a type I error is committed.

The correct choice is C.

Given : Nathan brings cupcakes to school and gives them to his five best friends, who share them equally.

i.e. Number of friends = 5

If c represents the number of cupcakes Nathan brings to school, then the number of cupcakes each of his friends receive is given by using division operation :_

$c\div 5=\dfrac{c}{5}$
