Travis was attempting to make muffins to take to a neighbor. The recipe that he was using required 3/4 cup of sugar and 1/8 cup

bogdanovich [222]

A. The recipe required 3/4 cup of sugar and 1/8 cup of butter.

The ratio of the sugar to butter in the original recipe is

$\dfrac{\frac{3}{4}}{\frac{1}{8}}=\dfrac{3}{4}\cdot \dfrac{8}{1}=\dfrac{6}{1}.$

B. If Travis accidentally put a whole cup of butter in the mix, then he needs to put

$\dfrac{3}{4}\cdot \dfrac{6}{1}=\dfrac{9}{2}=4\dfrac{1}{2}$ cup of sugar.

C. Travis has to put 1/8 cup of butter, but he put 1 cup of butter. The ratio is

$\dfrac{1}{\frac{1}{8}}=\dfrac{1}{1}\cdot \dfrac{8}{1}=\dfrac{8}{1}.$

If Travis wants to keep the ratios the same as they are in the original recipe, he needs to put 8 times more of all the other ingredients.

Yahoo creates a test to classify emails as spam or not spam based on the contained words. This test accurately identifies spam (

Amiraneli [1.4K]

Answer and Step-by-step explanation:

The computation is shown below:

Let us assume that

Spam Email be S

And, test spam positive be T

Given that

P(S) = 0.3

$P(\frac{T}{S}) = 0.95$

$P(\frac{T}{S^c}) = 0.05$

Now based on the above information, the probabilities are as follows

i. P(Spam Email) is

= P(S)

= 0.3

$P(S^c) = 1 - P(S)$

= 1 - 0.3

= 0.7

ii. $P(\frac{S}{T}) = \frac{P(S\cap\ T}{P(T)}$

$= \frac{P(\frac{T}{S}) . P(S) }{P(\frac{T}{S}) . P(S) + P(\frac{T}{S^c}) . P(S^c) }$

$= \frac{0.95 \times 0.3}{0.95 \times 0.3 + 0.05 \times 0.7}$

= 0.8906

iii. $P(\frac{S}{T^c}) = \frac{P(S\cap\ T^c}{P(T^c)}$

$= \frac{P(\frac{T^c}{S}) . P(S) }{P(\frac{T^c}{S}) . P(S) + P(\frac{T^c}{S^c}) . P(S^c) }$

$= \frac{(1 - 0.95)\times 0.3}{ (1 -0.95)0.95 \times 0.3 + (1 - 0.05) \times 0.7}$

= 0.0221

We simply applied the above formulas so that the each part could come
