The table shows the number of points forty students scored on a mathematics test. 48 23 58 50 61 46 58 61 55 43 78 53 77 52 55 45 59 53 55 39 42 43 72 46 65 66 64 29 69 73 27 56 48 44 71 61 52 63 33 35 a) Draw a stem-and-leaf plot. b) What is the range of the data? c) What is the mode? d) What is the median? e) What is the interquartile range?​

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

i will pick c put check it over to be sure

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
