Answer:
angles 2 and 3 are vertical angles
this is because they are opposing sides of the vertex while also congruent in size
Answer:
Angles 2 and 3
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
Centre of dilation
Dilation gives you a new shape that is either larger or smaller than the original.
In either case, every ray that passes through corresponding points of the two shapes will converge at the centre of dilation (Point O in the diagram).
Scale factor
To get the scale factor, you measure the ratio of lengths of corresponding sides in the shapes.
For example, a line in the red figure below may be four times as long as the corresponding line in the other.
If the dilation converts the blue shape into the red one, the scale factor is 4:1.
If the dilation converts the red shape into the blue one, the scale factor is 1:4.
Answer:Dilation scale factor 2: Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.
Answer:
1. The blue line is closer to the dots
2. About 8
3. 19 weeks
4. The trend line describes the pattern if one exists
5. The first one (as there is inclusion of first quarter point at 13-18 = 16 and it shows the midpoint along with 26 greater to filled hole as data reaches 27) But I feel the forth one shows the 23-28 clearer so go with the 4th one.
6. The population is decreasing over time.
P / T = decrease
Box Plot revision.
In descriptive statistics, a box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles. Box plots may also have lines extending from the boxes indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram.
Adding the student with eight siblings will increase the class average amount of siblings because this student has more siblings than the average.
The new class average for number of siblings is 3.19
Therefore, the average number of siblings that each student has is larger than the original average.
Answer:
The average will go up.
