The tree in your friend's yard casts a shadow that is 27 feet long. Your friend is 5 feet tall and casts a shadow that is 4.5 feet long. What is the height of the tree?

Answers

Answer 1

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer 2

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend

27ft : 4.5ft

? : 5ft

Formula given divided by the original or missing value equivalent

g/o = 5/4.5 = 1.11111 multiplier

Then use multiplier for the tree given value.

27 x 1.111111 = 29.999997

= 30ft

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Answers

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.

You asked amusement park visitors the question “How many times did you ride the Ferris wheel today?” as they left the park.

Four people said they rode a Ferris wheel 5 times. Explain how this would be shown on a dot plot.

Answers

Answer:

Draw an xy axis. On the x-axis, put "number of times person rode the Ferris wheel" or something along those lines. For the y axis, put "frequency". For x = 5, you'll have four dots stacked on top of each other at this x value. I suggest having a slight gap between each dot so you can tell them apart. The four dots represent the four people who said they rode the Ferris wheel five times.
