Apreschool field trip required 7 buses.
thirteen children rode in cars with their
parents and the rest rode on a bus. if there
were 258 children on the trip altogether,
how many were on each bus?
equation and answer

35 kids were on each bus

Step-by-step explanation:

258 = 7k + 13

k = kids on buses

First, subtract 13 from each side

245 = 7k

Divide each side by 7

35 = k

Step-by-step explanation:

Let the number of children in each bus = x

Total no. of children rode on bus = 7x

7x + 13  = 258

7x  = 258 - 13  

7x = 245

  x = 245/7

  x =35

There were 35  children on each bus.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

answer: the answer is b. i think hope i got it correct
