Bruce's three measurements are 19cm, 20cm, 23cm. calculate the average value of his measurements

We are given:

Bruce has three measurements measuring 19cm, 20cm, 23cm.

We need to find the average value of Bruce's measurements.

We know the formula of average is:

Where:

is the sum of observations

is the number of observations

average value of Bruce's measurements is:

Hence the average value of Bruce's measurements is 21cm

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
