7. Consider the expressions. 600 x 100 mL 600 x 10³ mL 6 x 10² x 1,000 mL a. Circle the expression that does not represent how t
o convert 600 liters to milliliters.
1 answer:
Answer:
Step-by-step explanation:
There are 1,000 milliliters in a liter. This means that in order to convert 600 liters to milliliters, you must multiply 600 by 1,000.
600 x 10^3 mL simplifies to 600 x 1,000 mL
The last expression is also 600 x 1,000 mL
The incorrect expression is the first one, since it is only multiplying by 100 mL instead of 1,000.

Answer:
The random variable (number of toppings ordered on a large pizza) has a mean of 1.14 and a standard deviation of 1.04.
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>The probability distribution is:</em>
<em>x P(x) </em>
<em> 0 0.30 </em>
<em>1 0.40 </em>
<em>2 0.20 </em>
<em>3 0.06 </em>
<em>4 0.04</em>
The mean can be calculated as:
(pi is the probability of each class, Xi is the number of topping in each class)
The standard deviation is calculated as:
