Hurry ! which of these measurements is more precise and explain why. explain the difference between precision and accuracy.

the first one (the one with more lines which is the centimeter (cm) one)

Step-by-step explanation:

Precision is when you know the exact measurement like 4.756

Accuracy is when your kind of close to the precise measurement like 4.75

Precision means exact and accuracy means close enough.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
