<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative. When you divide two integers with the same sign, the result is always positive.</span>
Answer:
0.13%
Step-by-step explanation:
Mean, u = 17.4%
standard deviation, sd = 27.5%
We are looking for the probability that the money will double in value. Therefore we are looking for the value of x = 100% (meaning the value is 100% more that the previous year)
Find the value of z-score
z = (x-u)/sd
= (100 - 17.4) / 27.5 = 3.003
Find the z score using the z-table
From z-table at P(z<3.003) = 0.9987
So, for the probability that it the money will be double is
P (Z>2.8982) = 1 - P(z<2.8982)
= 1- 0.9987
= 0.0013 = 0.13%
Answer:P(male | buys lunch) = 0.4 and P(male) = 0.3.
Step-by-step explanation:
There are 46+176 = 222 males.
There are 254+264 = 518 females.
There are a total of 740 people.
The probability of being male is 222/740 = 0.3
There are 46+254 = 300 people that bring lunch.
There are 176 + 264 = 440 people that buy lunch.
P(male | buy lunch) = 176 / 440 = 0.4
P(male | buys lunch) = 0.4 and P(male) = 0.3.
There are 3 choices for the bottom scoop. Then there are only 3 choices for the scoop above that (since one flavor has already been used), then 2 choices for the next scoop, and 1 choice for the final scoop. This gives a total of 18 <span>possible cones.
Hope this helps.
