Figure AA is a scale image of figure BB
Figure A maps to figure B with a scale factor of 1 1/2
Answer: x=3
Step-by-step explanation:
We know that the triangle got smaller. When you dilate by a scale factor of something, you multiply to make a number bigger or smaller. So x÷1.5= 2
x= 2x1.5
x= 3

Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.
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?
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.

Mr. Henry has a basket full of fruit. He does not
know how many pieces of fruit are in the basket
or the types of fruit. Each of the 20 students in
his class selects one piece of fruit from the basket
without looking, notes its fruit type, and then puts
it back in the basket. Based on the results shown
in the table, what can the students conclude
about the probability of selecting an apple?
Answer:
[tex]\frac{5}{20}[/tex] OR [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Simply put, the total amount of fruits in the basket is 20. Since there are only 5 apples, this makes you only have a 5/20 chance of picking an apple. If you simplify that ratio, you get 1/4.
Good Luck!!!!

Below is the graph of equation y=-lx-2l+2. Use this graph to find all values of x such that
a. y>0
b.y<0
c. y=0
THIS IS AN RSM promblem Please Help
The graph is a linear function defined by several pairs of coordinates, and the computation for x and y values is as follows.
Graph equationy=−|x−2|+2
When x=0
then
y=−|0−2|+2
y=−|−2|+2
y=−2+2
y=0
When x=1
then
y=−|1−2|+2
y=−|−1|+2
y=−1+2
y=1
When x=2
then
y=−|2−2|+2
y=−|0|+2
y=−0+2
y=2
When x=3
then
y=−|3−2|+2
y=−|1|+2
y=−1+2
y=1
When x=4
then
y=−|4−2|+2
y=−|2|+2
y=−2+2
y=0
When x=5
then
y=−|5−2|+2
y=−|3|+2
y=−3+2
y=-1
Hence, the value of (x, y) are as follows
y=0 x=0
y=1 x=1
y=2 x=2
y=1 x=3
y=0 x=4
y=-1 x=5

Which formulas will you use to find the area of this irregular figure? Select all that apply.
A = one-half b h
A=b+h
A=bh
A=2bh
A=2(b+h)
Here, two formulas we will use to find the area of this irregular figure.
A = one-half b × h
A=b + h
What is the area of a right-angle triangle?
The area of a right-angle triangle is = one-half × base × height = one-half b h.
What is the area of a parallelogram?
The area of a parallelogram = base × height = b h.
We can easily divide this irregular figure into a right-angle triangle and a parallelogram.
Hence, A = one-half b × h and A=b + h; two formulas will be required to find the area of this irregular figure.
