Jamie ask 40 random 8th grade students whether or not they had a curfew. Then she asked if they had a set bedtime on school nights. Th results are below. What is the marginal relative frequency of those students who had no bedtime? Total Curfew No curfew Total Bedtime 12 8 No Bedtime 6 14 20 40 18 40 O 6 14 14​

6/14

Step-by-step explanation:

The number under ''No Bedtime'' are 6 and 14 which makes the Marginal Relative, 6/14

Hope this helps <3

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
