Their is a lot of ways to use rational numbers in the world like miles per gallon,number of pages per hr.
Answer:
you didnt include the question-
Angela bought 4 casual shirts, and 6 dressy shirts.
To find this, I used the equation ($18c) + ($25d) = $222, and filled in for c (casual) and d (dressy) until the outcomes were the same. Filling in for c and d, you'll get ($18 * 4) + ($25 * 6) = $222. Solving both sides, you'll get $72 + $150 = $222 or $222 = $222. Thus meaning she bought 4 casual shirts and 6 dressy shirts,
I hope this helps!
Answer:
0.701
Step-by-step explanation:
Probability is the ratio of favorable outcomes to the total number of outcomes. It provides incite to likelihood an event to occur. Probability is a ratio , so it has no unit. It is sometimes expressed in percentage.
probability that the student intends to attend classes full time in pursuit of an MBA degree = 352/502 = 0.7012.
This kind of experiments are ruled by Bernoulli's formula. If you have probability p of "success", and you want k successes in n trials, the probability is

It's easier to compute the first probability by difference: instead of computing the probability of the event "at least one of the surveyed eats breakfast", let's compute the probability of its contrary: none of them eats breakfast. So, we want 0 successes in 4 trials, with probability of success 0.34. The formula yields

Since the contrary has probability 17%, our event "at least one of the surveyed eats breakfast" has probability 83%.
As for the second question, the event "at least three of the surveyed eats breakfast" is the union of the events "exactly three of the surveyed eats breakfast" and "exactly four of the surveyed eats breakfast". So, we just need to sum their probabilities:
