To draw a boxplot, you need to first find five values: (a) minimum (b) Q1 (first quartile) (c) median (d) Q3 (third quartile) (e) maximum Then draw an appropriate scale and make the boxplot. The minimum, median and maximum should not be difficult to find. Finding the quartiles is more work: (1) First, make sure numbers are in increasing order. (2) Locate the median (or solve for the median) (3) To find Q1 (first quartile): Find the median of ALL values that are below the median. (4) To find Q3 (third quartile): Find the median of ALL values that are above the median.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

but which class are u may know that first

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
