Carlos has a fair die and a number cube. He will flip the fair die one time and roll the number cube one time. What is the proba
saul85 [17]

Answer: 0.42 and 5 outcomes.

Step-by-step explanation:

i guess that carlos has a fair coin and a number cube.

the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.

The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2

the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6

the joint probability is the product of those two:

P = 1/2*5/6 = 5/12 = 0.42

The combinations that include heads and number greater than 1 are 5 combinations:

Heads and 2

Heads and 3

Heads and 4

Heads and 5

Heads and 6.

The cost of tuition at a 2 year school is $14,000 per academic year. Todd is eligible for $6,500 in financial aid to cover tuiti
emmainna [20.7K]

Answer:

$625

Step-by-step explanation:

If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:

2(-$14000 + $6500) + 2(12x) = 0.

x is the minimum amount of money he needs to save in order to cover this expense without debt.

Thus 2(-$14000 + $6500) + 2(12x) = 0 →

2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →

24x = $15000 → x = $625

HELP!!! TIMED ASSIGNMENT!!!!! PLEASE HELP
eduard

Answer:

see below

Step-by-step explanation:

The first part of the function, f(x) = -2x (for x < -1), is only graphed correctly in the first and third graphs.

The second part of the function, f(x) = -1 (for -1 ≤ x < 2) is only graphed correctly in the first graph, which also correctly graphs the third part of the function,

The appropriate choice is the first graph.
