1. Allie and Annika decided to keep track of the number of books they read during the year. The table shows the total number of books read for five months.
Number of Books Read
Reader Jan. Feb. March April May
Allie 7 3 12 5 8
Annika 4 2 9 7 5
(a) Create a box-and-whisker plot with a single number line to compare the two data sets. Use the minimum and maximum values of the data points to choose an appropriate scale for the number line.
(b) Which girl’s data set has the lesser median?
(c) How did you determine the value in the first quartile (Q1 value) for Allie?
(d) In which quarter of Annika’s data are the values most spread out? Explain.
(e) Compare the interquartile range (IQR) for both data sets. Show your work.

step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

pretty sure 750 each month!

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
