The director of a museum recorded the number of students and adult chaperones in several school groups visiting the museum. She

organized the data in a scatter plot, where x represents the number of students and y represents the number of adult chaperones. Then she used a graphing tool to find the equation of the line of best fit: y = 0.123x + 5.397. Based on the line of best fit, approximately how many students are predicted to be in a school group with 20 adult chaperones? A. 8 B. 119 C. 157 D. 206

AlexFokin [52]

Answer:

10

Step-by-step explanation:

<h3>Calculating BC</h3><h3>BC = √2^2 + 11^2 </h3><h3>BC = √ 4+121</h3><h3>BC = √ 125 = 11.18</h3>

to find measure of angle C use sinerule

<h3>sinC/C = sinA/A</h3><h3>sinC/2= Sin90/11.18</h3><h3>SinC = 2×1/11.18</h3>

<h3>sinC = 2/11.18</h3><h3>sinC = (0.1788)</h3><h3>C = sin^-1(0.1788)</h3>

<h3>C = 10.305</h3><h3>C = 10 (approximately)</h3>
