Answer:
Jasmine only.
Jasmine and Kanti only.
No one.
Step-by-step explanation:
There is no possible way to invite all three friends.
Since both Samir and Kanti will not attend if someone else is not invited, Jasmine is the only friend that can be invited on her own:
One person: Jasmine.
When inviting two people, if Jasmine is invited, Samir can't be invited and Kanti will only attend if Jasmine also does. Therefore, Jasmine and Kanti can go together and there is no way Kanti can be invited.
Two people: Jasmine and Kanti.
Furthermore, if nobody is invited, no one will be unhappy.
RM298
reason: multiply RM4 by 10 to get RM40 and add that to RM258 to get RM298
Answer:
Standard deviation 46.3
Step-by-step explanation:
A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.
Z score is calculated as follows:
x is the number being evaluated
μ is the mean
σ is the standard deviation
And it is used to calculate how many standard deviations you are from the mean of the sample.
Replacing with the known information you can calculate the standard deviation:
Answer:
D. It is the product of the initial amount and the decay factor after w weeks.
Step-by-step explanation:
We are told that Ariana starts with 100 milligrams of the substance. The number 100 in the expression likely represents this amount, <em>the initial amount</em>. It is multiplied by another number, so is part of a product. (It is not part of a difference, and is not something that is raised to a power.)
The factor (1 -0.2) represents the fraction remaining at the end of a week. That number raised to the power w will represent the fraction remaining at the end of w weeks. This fraction can reasonably be referred to as "the decay factor after w weeks."
Hence, the expression represents ...
<em>the product of the initial amount and the decay factor after w weeks</em>
