Suppose you start with $52 in your savings account and deposit $27 each week. Write an inequality to describe how many weeks, w, it will take you to have enough money to buy a bike that costs $340. Then solve the inequality to determine how many months it will take you. CHECK ALL THAT APPLY: (put the letters that are correct) A. 52w + 27 ≤ 340

B. 27w+52 ≤ 340

C. 52w + 27 ≥ 340

D. 27w + 52 ≥ 340

E. 10 weeks or more

F. 10 weeks or less

G. 11 weeks or more

H. 11 weeks or less

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments. which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8

Drag the tiles to the correct boxes to complete the pairs. label each function. as even , odd, or neither.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
