PLEASE HELP ME Select EACH STATEMENT about the function graphed here. (Remember - the B-value tells you how many cycles the function completes from [0, 2pi])

The statements are:

The function is a sine function

The function is a cosine function

The function has not been reflected in the x-axis

The function has been reflected in the x-axis

The functions period is 2 units

The functions period is 1 unit

The functions period is 0.75 units

The functions B-value is 2

The functions B-value is 2pi

The functions B-value is pi

The function has not been shifted up or down

The function has been shifted down one unit

The functions C-value (vertical shift) is -2

The functions midline is y=-1

Aclothing designer is selecting models to walk the runway for her fashion show. the clothes she designed require each model’s height to be no more than y inches from 5 feet 10 inches, or 70 inches. which graph could be used to determine the possible variance levels that would result in an acceptable height, x?

Why is causation so much more difficult to prove than correlation?

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
