Which of the following is a reasonable estimate for the weight of an 18-wheeler truck?
a.
8 × 10-4 lb
b.
8 × 102 lb
c.
8 × 10-2 lb
d.
8 × 104 lb

The reasonable estimate for the weight of an 18-wheeler is

Step-by-step explanation:

The average and legally maximum weight of an 18-wheeler is 80,000 pounds.

From option a through d, we check which of the measurement is close or equivalent to 80,000 pounds

By converting this, we have

By converting this, we have

By converting this, we have

By converting this, we have

From the 4 conversions, only   is equivalent to the average and legally maximum weight of an 18-wheeler, 80,000 pounds.

Hence, the reasonable estimate for the weight of an 18-wheeler is

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
