Answer:

Part A : 9.555 . 10^38

Part B : 7.4 . 10^-3

Step-by-step explanation:

<h3>Part A</h3>

3.9 \: . \:  {10}^{33} . \: 2.45 \: . \:  {10}^{5}  \\ 3.9 \: . \: 2.45 \: . \:  {10}^{33 + 5}  \\ 9.555 \: . \:  {10}^{38}  \\

<h3>Part B</h3>

7.4 \: . \:  {10}^{ - 3}mm  \\ 7.4 \: . \:  \frac{1}{ {10}^{3} }  \\ 0.0074mm

7.4 \: . \:  {10}^{3}mm  \\ 7.4 \: . \: 1000 \\ 7400mm

A blood cell is too small. So the more reasonable measurement is 0.0074mm.

Roll a number cube. If the number cube comes up odd, you win the same number of points as the number on the cube. If the number
laila [671]

Answer:

–0.5

Step-by-step explanation:

Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.

The odd rolls are 1, 3 and 5.  The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.

The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.

The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.

Rolling any even number gives us the same value.  The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.

Together we have

1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5
