Suppose we want to study the errors found in the performance of a simple task. we ask a
large number of judges to report the number of people seen entering a major department
store in one morning. some judges will miss some people and some will count others
twice, so we don’t expect everyone to agree. suppose we find that the mean number of
shoppers reported is 975 with a standard deviation of 15. assume that the distribution of
counts is normal.
75% of the counts would be less than – 3 pts.
95% of the counts would be between and – 3 pts.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
