Answer:
m = 10t
Step-by-step explanation:
Let m represent the total money
Let t represent the number of hours
Answer:I have no idea
Step-by-step explanation:
Ok
With one single year of records, we do not have a reliable way to choose the place with a warmer mean temperature, given that the median temperatures are close.
The choice of the answers depend a lot on the justifications.
first answer: the justification (Orlando has a higher IQR) is incorrect, so eliminated.
second answer: the justification is based on the premise that mean is usually close to the median, given symmetric distributions. Since both distributions are not too skewed, this option could be retained.
third answer: higher maximum temperature with a lower median could mean that it is a once in a while occurrence, and may not generalize.
fourth answer: the justification is not unreasonable, with a greater IQR in Tempa Bay, and the mean of Q1 and Q3 (68) is higher than the median temperature of Orlando, there is a chance that its mean temperature (last year) is higher.
All in all, I personally believe Orlando is a better bet because the justifications "higher median and smaller IQR" (opt.2) are more concrete and more convincing than the "chance" (opt. 4) that the mean is higher in Tempa Bay.
Answer:
a) 0.076
b) 0.5
c) 0.084
d) 0.25
e) 0.00024
f) 0.156
Step-by-step explanation:
a) In an ordinary deck there are 4 aces. The probability of getting an ace is given by:
n: options for an ace = 4
N: total number of cards = 52
The probability is 7.6%
b) On the first 100 positive integers, there are 50 odd integer numbers. Then you have:
The probability of getting an odd number is 50%
c) From a total of 365 day in the year, May has 31 day. Then you have:
The probability is 8.4%
d) In this case you have two events. To get an odd number with the sum of the number of two dices you need and odd number in one dice and a pair number in the other dice.
The probability is the product of the occurrence of both events. The probability for an odd number is 1/2 and for a pair number is 1/2.
The probability is 25%
e) To obtain Head 6 times in a row, the probability is:
Probability of 0.024%
f) To get Head 4 times from 5 flights, you first calculate the probability for 1 head in five flips:
There are 5 forms of getting 4 Heads for 5 flips, then you have:
Te probability is 15.6%
