1 answer:
Radda [10]3 years ago
4 0

Answer:

i believe it is C

Step-by-step explanation:

the power of 10 on left is negative so if you add 2, it will be 0 to power of 10, so it is plus 4 on power or 10. Then with the main number,you subtract 9 from 3 and that is 6. So, 6 times 10 to the power of 4.

Suzy randomly picks marbles form a bag containing 13 identical marbles. how many possible outcomes are there of she selects 10 m
allsm [11]

Answer:

 286 possible outcomes.

Step-by-step explanation:

We have been given total 13 identical marbles

We need to select 10 out of 13

We will use combination:

^nC_r=\frac{n!}{r!(n-r)!}

here,n=13 and r=10 on substituting the values in the formula we get:

^13C_{10}=\frac{13!}{10!(13-10)!}

^13C_{10}=\frac{13\cdot 12\cdot 11\cdot10!}{10!\cdot 3!}

\Rightarrow ^13C_{10}=\frac{13\cdot12\cdot11}{3\cdot2\cdot1}

\Rightarrow 286

So, there are 286 possible outcomes.
