Answer:
A. No, this is not a valid inference because he asked only 20 families
Step-by-step explanation:
You cannot assume that those are the only families that would want to go; you have to ask all the families.
Let c = number of children
Let a = number of adults
5a + 2c > 3350
Answer:
Answer 5 1/4
Step-by-step explanation:
The amounts of sugar, butter, and flour used are 150 grams, 225 grams, and 450 grams, respectively.
Anders makes scones with three ingredients : sugar, butter, and flour. The ratio of the amounts of sugar, butter, and flour is 2:3:6. The available amounts of the ingredients in the kitchen include 200 grams of sugar, 300 grams of butter, and 450 grams of flour. He makes as many scones as he can with these ingredients.
Let the amounts of sugar, butter, and flour be 2x, 3x, and 6x, respectively. The maximum proportion is for flour. The amount of flour used is 450 grams. The amount of butter used is half of that of the flour. The amount of sugar is one-third of that of flour.
B = (3x/6x)*450 = 225
S = (2x/6x)*450 = 150

Answer:
KK KL KM KN KP LL LM LN LP MM MN MP NN NP PP
Step-by-step explanation:
Instead of starting with adjacent letters in the list, we start with the same letter. There are 15 possible pairs.
KK KL KM KN KP LL LM LN LP MM MN MP NN NP PP
__
<em>Additional comment</em>
We leave out pairs with letters previous, because you've said KL is the same as LK, and KL has already been listed. The problem with this list is that it misstates the probabilities of randomly obtaining a given pair. It is not 1/15, but is 2/25 for all but letter duplicates. For duplicates (KK), the probability is 1/25, not 1/15.
