Answer:

Step-by-step explanation:

The total number of ounces contained by all the big bottles is the number of big bottles multiplied by the the number of ounces a big bottle can contain.(57×40)

The total number of ounces contained by all the small bottles is the number of small bottles multiplied by the the number of ounces a small bottle can contain.(38×20)

To find n, you add the two operations, (57×40) and (38×20). So the equation would be

57×40+38×20=n

Answer:

Step-by-step explanation:

Since they have 57 40-ounce water bottles, you need to have 57x40. Since they have 38 20-ounce bottles in stock, you need to have 38x20. Sinc ehte problem is asking for the total ounces in all, you need to add them. We do not need to add parentheses because PEMDAS

So,

57 x 40 + 38 x 20= n

if a coin is tossed 4 times, the odds of it coming up either heads every time or tails every time are 1:7.What is the probabilit

ivanzaharov [21]

Answer:

$1$

Explanation:

From the question, we have it that the probability of heads coming up every time or tail coming up every time is 1:7 if the coin is tossed in 4 tosses

What this means is that we have a probability of 1/8 of head showing up and a probability of 7/8 that a tail will show up in each toss of the coin

For four throws, it means all four are heads or all four are tails

If all four are heads, we have the probability of this happening as:

$\text{ (}\frac{1}{8})^{}$

if all four are tails, we have the probability as:

$\frac{7}{8}$

Now, the probability of either heads or all tails after 4 tosses will be:

$\text{ }\frac{1}{8}\text{ + }\frac{7}{8}\text{ = 1}$
