Answer:

Step-by-step explanation:

Given that integral approximation formula is calculated as follows:

Integral from a to be of f(x) dx is calculated as dividing the region between the curve, the x axis and y=a and y=b into a number of trapeziums (n) of equal width and then calculating the area of the trapeziums and adding.

The width of triangle would be (b-a)/n

The length would vary depending on the position of x.

First rectangle has length = y_0 = f(a)

Hence left end points are used

So this is Riemann left sum approximation.

scoundrel [369]

Answer:

4

Step-by-step explanation:

  • If you take the lowest half of the data (from the lower extreme to the median) and find the median of these numbers, that is called the lower quartile or quartile 1.
  • If you take the upper half of the data (from the upper extreme to the median) and find the median of these numbers, that is called the upper quartile or quartile 3.
  • The interquartile range is the difference between quartile 1 and quartile 3.

  • 4, 5, 6, 8, 9, 10, 11, 13
  • Median=8.5
  • Q1=6.5
  • Q3=10.5
  • 10.5-6.5=4

Answer:f(1)=-4, f(1)=1

Just substitute the value to the x, Like this.

F(x)=x²+2x-7

F(1)=(1)²+2(1)-7
