Answer:

24.32 and 30

Step-by-step explanation:

you have to cross multiply. x time 18.1 is 18.1x. multiply 136.56 by 3.2 and get 440.192. Then divide 440.192 by 18.1 and get 24.32. Do the same steps for the other problem and get 30.

Iteru [2.4K]

Complete Question

Christine has always been weak in mathematics. Based on her performance prior to the final exam in Calculus, there is a 42% chance that she will fail the course if she does not have a tutor. With a tutor, her probability of failing decreases to 12%. There is only a 52% chance that she will find a tutor at such short notice

a What is the probability that Christine fails the course

b Christine ends up failing the course. What is the probability that she had found a tutor? (Round your answer to 4 decimal places.) Probability

Answer:

$P(F) = 0.264$

$P(T | F ) = 0.23636$

Step-by-step explanation:

From the question we are told that

The probability that Christine will fail the course if she does not have a tutor is $P(F| T') = 0.42$

The probability that Christine will fail the course if she has a tutor is $P(F| T) = 0.12$

The probability that she will find a tutor is $P(T) = 0.52$

Generally the probability that she will not find a tutor is

$P(T') = 1 - 0.52$

=> $P(T') = 0.48$

Generally the probability of failing the course is

$P(F) = P(F \ n \ T) + P(F \ n \ T')$

=> $P(F) = P(F| T) * P(T) + P(A | T') * P(T')$

=> $P(F) = 0.12 * 0.52 + 0.42* 0.48$

=> $P(F) = 0.264$

Generally if Christine ends up failing the course the probability that she had found a tutor? (Round your answer to 4 decimal places.) Probability is mathematically represented as

$P(T | F ) = \frac{ P(F | T) * P(T)}{ P(F)}$

=> $P(T | F ) = \frac{ 0.12 * 0.52}{ 0.264}$

=> $P(T | F ) = 0.23636$

ziro4ka [17]

Answer:

Step-by-step explanation:

Distance of yellow to white = 8 inches which is given

The green ball is at the midpoint of red to white.

Since the green ball is 10 inches to the red ball, the green ball is also 10 inches from the white ball. That's what a midpoint is.

The yellow ball is closer.
