There are 221 students on a field trip.

DerKrebs [107]

The number of students in each bus is an illustration of a linear function

The equation that represents the number of students in each bus is: $\mathbf{s= \frac{216}{6}}$

The number of students is given as:

$\mathbf{Students = 221}$

Subtract 5 from the equation, to get the number of students that fill the bus

$\mathbf{b= 221 - 5}$

$\mathbf{b= 216}$

Divide both sides by 6 to get the number of students in a bus

$\mathbf{\frac{b}{6}= \frac{216}{6}}$

Represent students in the bus with s

$\mathbf{s= \frac{216}{6}}$

Hence, the equation that represents the number of students in each bus is: $\mathbf{s= \frac{216}{6}}$

A data set has a mean of 720 and a standard deviation of 6. which is closest to the z-score for an element of this data set with

lisabon 2012 [21]

Mean = u = 720
Standard deviation = s = 6
Data Value = x = 709

The formula to calculate the z score is:

$z= \frac{x-u}{s}$

Using the values, we get:

$z= \frac{709-720}{6} \\ \\ 
z=-1.83$

Thus the z score for the data value will be -1.83.

Use the figure below for Exercises 1-8. Note that RN pierces the plane at N. It is not coplanar with V.

Serga [27]

Answer:

1. Two segments are MC and AX

2. Point N

3. Three collinear points are points A, point N and point X

4. Two other names for V are quadrilateral and rectangle

5. No N, M, and X are in a different plane from R

6. Two rays are ray NR and ray NA

7. The pair of opposite rays with end point N are ray NA and ray NX and ray NM and ray NC

8. Three lines are shown in the figure

Step-by-step explanation:

1) A segment is a line portion with two end points

2) A point marks a position

3) Collinear points are points on the same line

3) A quadrilateral is a four sided figure while rectangle has 90° interior angles

4) A ray is an line extending from a point without ending

5) Opposite rays are rays extending from the same point but in opposite directions

6) A line is a straight one dimensional geometric figure that has no width but infinite number of points extending without end in both directions
