Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%
Step-by-step explanation:
Step 1
Time as recorded by the stopwatch = 4.82 seconds
Real Time it takes for a Frisbee to fly through the air =5.05 seconds
percent error = Measured value – True Value /True value x 100.
= 4.82 - 5.05 / 5.05 x 100
=-0.23/5.05
=-0.0455 x 100
=4.5544%
Rounding to nearest 10th of a percent = - 4.6%

I've included a graph to show you another way that you could get closer quicker.
The red line is y = 2x - 3
The blue line is y = x^2 - 5
Answer:
Step-by-step explanation:
Move the decimal point in the divisor and dividend.
Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.
Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Line up each digit in the quotient just over the last digit in the dividend used in that cycle.
The <em><u>correct answer</u></em> is:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.
