Add them all and then divide by the number of days (by 5)
The type of land form that Caleb most likely draws is a hill. The answer is option C- a hill.
Step-by-step explanation:
- Contour lines are <u>drawn to represent the changes in the elevation</u> which helps to know the slope of the figure drawn.
- If the contour lines are drawn close, then steeper the figure is. And more distant the lines are drawn, then less steep the figure is.
- Here, the lines seem to be likely circle in shape. The distance of the outermost contour line is 20 ft. The <u>next inner lines will have reduced values of 20 ft.</u>
- Therefore, <u>the elevation gets reduced from higher to lower points</u> which provides a diagram of a hill. Since there is no continuous high and low elevations, this cannot be a valley (a range of mountains).
- Furthermore, The contour diagram for option A and D such as creek(water stream) or shoreline will have different and mixed values of elevations that seems to be a messy structure of contour lines.
Step-by-step explanation:
that's for Part B
Part C: triangles PQR and P"Q"R" are not congruent since the corresponding sides are not equal
Answer:
x = - 9
Step-by-step explanation:
Step 1:
2x - 3 = - 21 Equation
Step 2:
2x = - 18 Add 3 on both sides
Step 3:
- 18 ÷ 2 Divide
Answer:
x = - 9

Answer: .C. The population is the 10,900 respondents to the American Time Use Survey.
Step-by-step explanation:
In statistics , Population is refer to a large group of individuals or observations that have same characteristics.
A sample is a subset drawn from it.
We are given that "The 2015 American Time Use survey contains data on how many minutes of sleep per night each of 10,900 survey participants estimated they get. An SRS (simple random sample) of 100 of the participants has a mean time of x¯=514.4 minutes. "
i.e. The population is 10,900 respondents to the American Time Use Survey.
