B. 42, 43

Step-by-step explanation:

STEP 1 Listing out the data set

Country Time with dad

Belgium 30

Canada 44

China 54

Finland 50

Germany 36

Nigeria 42

Sweden 46

United States 42

STEP 2--- finding the mode and median

ModeThe mode of this data set is the number that occurs most frequently in this research date.

Time with dad in ascending order is given as 30, 36, 42, 42, 44,46,50,54

The number that occurred the most is 42 = mode

Median The median is the middle value in a data set

Since these data set is an even number, we take the average of the two middle numbers

Arranging in ascending order, we have

30, 36, 42, 42, 44, 46, 50, 5442 and 44 are the middle numbers

42+ 44/2 =43

Therefore mode and median are 42 and 43 respectively

Answer: choice c and choice d

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

Which functions have an additive rate of change of 3? check all that apply

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
