The mistakes that Joan made are:
- The y-axis does not start from zero.
- The width of the bars are not equal.
- The space between the bars are not equal.
<h3>What is a bar chart?
</h3>
A bar chart is a graph that shows the numerical values of variables represented by the height rectangles of equal width.
In a bar graph, the rectangles must be of equal width and the space between each bars must be equal.
Please find attached an image of the bar chart. To learn more about bar charts, please check: brainly.com/question/18092827

The answer is 3/2
you can divide each or one of the vertice(s) of the triangle A'B'C' by the triangle ABC to find the scale factor of dilation..... So
vertice of A and A'
A' (7.5)/ (5) A= 1.5 3/2=1.5
A' (4.5)/(3) A=1.5
So, if we put 3/2 in decimal is equal to 1.5, and 1.5 is the scale factor of this dilation between the division of the vertice A' by vertice A
Answer:
1.5
Step-by-step explanation:
Because the triangle are similar, they possess a proportional relationship in which the one triangle's side length is dilated by a unknown factor (y) to make its corresponding counterpart. Using this knowledge we can make the following two equations
3y=7 & xy=x+2 y is the variable representing the dilation factor
y=7/3 find the value of y
x(7/3)=x+2 substitute the value y into the equation
7/3x =x+2 solve for x
4/3x =2
(3/4)(4/3x)=2(3/4) multiply by the reciprocal
x=1.5
