Answer:
6
Step-by-step explanation:
3z = 18
Divide boboth sides by 3
3z/3 = 18/3
z = 6
Answer:
3?
Step-by-step explanation:
Answer:
294.5 m²
Step-by-step explanation:
shaded region = area of major sector + area of triangle
central angle of major sector = 360° - 130° = 230°
area of sector = area of circle × fraction of circle
A = π × 11.1² × ![\frac{230}{360}](https://tex.z-dn.net/?f=%5Cfrac%7B230%7D%7B360%7D)
=
≈ 247.3 m²
area of triangle = 0.5 × 11.1 × 11.1 × sin130° ≈ 47.2 m²
shaded area = 247.3 + 47.2 ≈ 294.5 m²
Answer:
Top left graph
General Formulas and Concepts:
<u>Statistics</u>
- Scatter Plots
- Best Line of Fit
Step-by-step explanation:
The best linear model for the data would be the best line of fit for the data. We can eliminate the rightmost graphs as they have no correlation with the data.
Between the leftmost graphs, we can see that the top left graph would be choice as it encompasses most of the data/is more of the data's average than the bottom one.
