Well if there are 3 outcomes just add the two other outcomes and subtract from 1

so 0.4+0.25=0.35

so the third outcomes has a 0.35 chance of happening or 35%

On a recent day a Euro was equal to about 1.2 American dollars. Write an expression which estimates the number of dollars in x E

JulsSmile [24]

Answer:

d = 1.2e

30 dollars

Step-by-step explanation:

To write an expression, define the variables. E will be the number of euros and d will be dollars.

"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.

This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.

If I have 25 euros then d = 1.2*25 = 30 dollars.

LaTonda rolls two number cubes that are each numbered 1 through 6. What is the probability that the sum of the numbers on the to

ZanzabumX [31]

Answer:

1/4

Step-by-step explanation:

The maximum sum of the two cubes is 6 + 6 = 12

The multiples of 4 until 12 are: 4, 8 and 12.

each cube has 6 possible values, so two cubes have a total of 6 * 6 = 36 possible results

We can have a sum of 4 with the pairs (1,3), (2,2), (3,1).

We can have a sum of 8 with the pairs (2,6), (3,5), (4,4), (5,3), (6,2)

We can have a sum of 12 with the pair (6,6)

So we have a total of 9 pairs that satisfy our condition over a total of 36 possibilities, so the probability is 9 / 36 = 1/4

spayn [35]

Answer:

B. 13

Step-by-step explanation:

To find the missing hypotenuse of a right triangle we can use this formula:

$c = \sqrt{(a^{2} } +b^{2} )$

Lets solve:

$c = \sqrt{5^{2} + 12^{2} }$

$c = \sqrt{25 + 144}$

$c = \sqrt{169}$

$c = 13$
