Help pls ;) <br> Find the geometric mean of 14 and 20

Kipish [7]

Answer:

The geometric mean of 14 and 20 is 16.73.

Step-by-step explanation:

It is required to find the geometric mean of 14 and 20. Let the numbers are :

a = 14 and b = 20

The geometric mean for two numbers is given by :

$M=\sqrt{ab}$

Plugging the values in above formula as follows :

$M=\sqrt{14\times 20}\\\\M=\sqrt{7\times 2\times 5\times 4} \\\\M=16.73$

So, the geometric mean of 14 and 20 is 16.73.

Every day, two student council members are randomly chosen to read the morning announcements. Students cannot be chosen more tha

Nesterboy [21]

<u>Complete Question</u>

The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.

Number of Students

Grade 7 - 17
Grade 8 - 34

Answer:

C- The number of outcomes representing each grade level does not change after the first student is chosen.

Step-by-step explanation:

The ratio of Grade 7 students to Grade 8 students is:

17:34

This written in reduced form is 1:2

Therefore, initially, the six parts of the cube can be divided into the ratio 2:4 which Jeremy did.

However, after the first selection of a student, the ratio of Grade 7:Grade 8 student changes since the same student cannot be chosen more than once.

Therefore the cube rolls represent only the first student choice and may not be accurate for subsequent rolls.

The correct option is C.

What happens to the sign or signs of the coordinates when you reflect a point?

elena55 [62]

Part a: Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes, changes the signs of both the coordinates.

Explanation:

Part a: Reflecting a point across the x-axis

The reflection is a transformation of a figure which represents a flip.

The rule for a reflection over the x -axis is given by

$(x, y) \rightarrow(x,-y)$

Hence, this represents the change of sign of the y-coordinate.

Thus, Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis

The rule for a reflection over the y -axis is given by

$(x, y) \rightarrow(-x, y)$

Hence, this represents the change of sign of the x-coordinate.

Thus, Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes

The rule for a reflection across both the axes is given by

$(x, y) \rightarrow(-x, -y)$

Hence, this represents the changes the signs of both the coordinates.

Thus, Reflecting a point across both the axes, changes the signs of both the coordinates.
