If the Probability of an event happening is 70%, what are the ODDS of the event happening?

elena55 [62]

Answer:

a) 7:10

Step-by-step explanation:

An example of this would be having seven blue marbles and three red marbles in a jar. If you randomly select one, the chance of that marble being blue is seventy, because 10 (total number of marbles) divided by seven (number of blue marbles) is 0.70, and if you convert this to a whole number (by multiplying it by 100) you get 70.

Find the missing value. (√24-√k)(√24+√k)=5

Anna [14]

Answer:

k = 19

Step-by-step explanation:

Identity

(a + b)(a - b) = a² - b²

Simplifying the LHS (Left Hand Side)

(√24-√k)(√24+√k)
(√24)² - (√k)²
24 - k

Equating to the RHS

24 - k = 5
k = 24 - 5
k = 19

Bonita is testing prototype model rocket engines. To be considered a successful launch, the rocket must reach a height of at lea

lbvjy [14]

Answer:

(0, 33) : Yes

(4.8, 30.5) : Yes

Step-by-step explanation:

height of at least 24 ft : y >= 24

horizontal distance of no more than 10 ft. : 0 <= x <= 10

The vertical height must be at least three times as high as the horizontal distance. No rocket should go higher than 33 ft.:

y >= 3x and y <= 33

So Constraints:

24 <= y <= 33

y >= 3x

0 <= x <= 10

Now check to see if those coordinate points meet all the constraints

(0, 33) : Yes

(4.8, 30.5) : Yes

(9, 26) : No (because 26 is less than (3 * 9) = 27)

(4, 36) : No (because 36 > 33, must be 24 <= y <= 33)

(2, 22): No (because 22 <24, must be 24 <= y <= 33)

Please explain your answer! Which of the following best represents time preference?

igomit [66]

Answer:

B. Alex smokes a pack of cigarettes per day even though he knows that he may face poor health down the road because of his smoking habit.

Step-by-step explanation:

Time preference means that the person would like to have temporary but instant satisfaction. In this case, B would be the best choice, for Alex wants to experience the "high" (I guess?) from smoking, even when he knew that there would be health consequences down the road.

In this case, it is not:

A, for Thomas is not going to receive his reward (a profit from the investment) until later on. The money he invest is still "there", but it is technically gone into investment.

C, because this is assuming that retirement is a long way off, and that this would be a long-term investment, rather than a short term.

D, this is a long-term investment, as Sarah "hopes" that she can earn it all back in the future. With what she learns, she, in the long run, wants to find a sustainable & high-paying job.
