Jed needs to estimate the value of StartFraction 4.32 times 10 Superscript negative 4 Baseline Over 8.71 times 10 Superscript negative 9 Baseline EndFraction. Which statements should he consider? Check all that apply.
4.32 divided by 8.71 is approximately 2.
4.32 divided by 8.71 is approximately 0.5.
The answer will be very small because Negative 4 minus 9 = negative 13.
The number will be large because Negative 4 minus (negative 9) = 5.
He will need to rewrite the preliminary result in scientific notation.
The number will be small because the exponent will be a fraction.

the answer is c. hope this !

step-by-step explanation:

the correct answer is $7.38

step-by-step explanation:

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
