WITCHER [35]

Answer:

a) The number of students in your school.      

Step-by-step explanation:

Quantitative and Qualitative:

  • The data that can be expressed with the help of numerical are know as quantitative variable.
  • Qualitative variable is the non parametric variable and numerical does not describe the data

Discrete and Continuous data:

  • Discrete data are expressed in whole number and cannot take all the values within an interval.
  • Continuous variable can be expressed in decimals and can take any value within an interval.

a) The number of students in your school.

Since whole numbers are used to express number of children it is a discrete and continuous data.

b) The different colors of the eyes of your classmates.

These are qualitative data and numerical are not used to express them.

c) The height of all the people in your neighborhood.

These are continuous data as height is measured and can be expressed in decimals.

d) The acceleration of your car as you drive to school.

In △ABC, D is a point on side AC¯¯¯¯¯¯¯¯ such that BD=DC and ∠BCD measures 70∘. What is the degree measure of ∠ADB?
777dan777 [17]
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal.   So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.   

Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
