A bottle of shampoo has a capacity of 0.43 L. How many milliliters of shampoo does the bottle contain? (1 L = 1,000 mL) A. 4.3 m

Finger [1]

Answer:

The correct answer is C

C. 430 mL

Step-by-step explanation:

We know that 1 liter is equivalent to 1,000 milliliters

1L = 1,000mL

So the number we have to go from liters to milliliters we multiply it by 1,000 and change the L per mL

0.43L = 0.43 * 1000 mL

0.43L = 430 mL

The bottle of shampoo contain 430 mL

if we look at the options they give us, we will see that it is equal to option c

A. 4.3 mL

B. 860 mL

C. 430 mL

D. 43 mL

A bag contains 42 red marbles, 6 white marbles, and 8 gray marbles. You randomly pick out a marble, record its color, and put it

Elanso [62]

For any single draw,

$\mathbb P(\text{white})=\dfrac6{42+6+8}=\dfrac6{56}$
$\mathbb P(\text{gray})=\dfrac8{42+6+8}=\dfrac8{56}$

Drawing a white marble or a gray marble are disjoint events; only one of them can happen. So

$\mathbb P(\text{white or gray})=\mathbb P(\text{white})+\mathbb P(\text{gray})-\underbrace{\mathbb P(\text{white and gray})}_0$
$\mathbb P(\text{white or gray})=\dfrac6{56}+\dfrac8{56}=\dfrac{14}{56}$

Out of 224 draws, you should expect $\dfrac{14}{56}\times224=56$ of the marbles to be either white or gray.
