B. 0.694

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that the pain reliever is advertised as being 97% effective, for it to be effective in 12 independent trials

= (97%) ^ 12

gavmur [86]

Answer:

44.1 x 10^-2

Step-by-step explanation:

Since one grain

= 7 x 10^-5

6300kg = 7 x 10^-5 x 6300

Put 6300 in standard form

7 x 10^-5 x 6.3 x 10^3

Multiply the whole numbers and add the exponents

7 x 6.3 x 10^-5 + 3

44.1 x 10^-2

There are 44.1 x 10^-2 grains of sand in 6300kg

Answer:

$21.79 + c \leq 25$

Joshua can spend up to 3.21 on a card.

Step-by-step explanation:

$21.79 + c \leq 25$ is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.

To solve, first subtract 21.79 from both sides to get: $c \leq 3.21$ . This means that Joshua can spend up to 3.21 on a card.

Hope it helps!
