Answer:
The probability that the red card came from the first stack is:
40%
Step-by-step explanation:
a) Data and Calculations:
Stack Red Blue Total
First 6 5 11
Second 9 0 9
Total 15 5 20
The probability of selecting from the first stack = 50% since equal opportunity is given to the two sacks.
The probability of red card from the first stack = 6/15 = 0.4 = 40%.
b) The probability that the red card came from the first stack is given by the number of red cards in the first stack divided by the number or red cards in the two stacks. This is equal to 6/15 = 0.4 or 40%.

putting x = 11,
we get,

Answer:
a) 24×10^-7
Step-by-step explanation:
The number is ...
0.0000024 = 2.4×0.000001 = 24×0.0000001
The first of these equivalents can be written as ...
2.4×10^-6 . . . . matches no answer choice (correct answer)
The second of these can be written as ...
24×10^-7 . . . . matches choice (a)
__
Usually "scientific notation" requires there be one digit left of the decimal point in the mantissa. As we have noted above, no offered answer choice matches this form. The only choice that is equivalent to the given number is the one shown above.
Answer: 6062

<u>Multiply</u>
<u>How is 6×10^3 6000?</u>
Before you multiply the whole equation you first Multiply 10 3 times. This is called an Exponent. In my own words, an exponent is a number that tells you how many times to multiply that number. So if we had 6^2 I will multiply 6×6 2 times. So we multiply 10×10×10 and get 1000. Then we multiply 6×1000 and get 6000.
<u>Add</u>
Since the final step is to add we Add the answer we got for 6.2×10 and 6×10^3.
Therefore we are adding 62*6000 and we get 6062.
