Answer:

$257$

Step-by-step explanation:

We want to evaluate:

$5(41 - x) + ( - 7(y + x)$

for x=-2 and y=-4.

We substitute to get:

$5(41 - - 2) + ( - 7( - 4 + - 2)$

We now simplify to get:

$5(41 + 2) - 7( - 6)$

$5 \times 43 + 42$

$215 + 42 = 257$

Answer:

The probability is $2.7327 \times 10^{-9}$

Step-by-step explanation:

The probability of guessing correctly, P = 0.54

Probability of not guessing correctly, q = 1 – P

q = 1 – 0.54 = 0.46

Number of trials, n = 32

Now calculate the probability that Mr. Taylor will pick 32 correctly in first round of the game.

Below is the calculation using binomial distribution.

$Probability = \left ( _{k}^{n}\textrm{} \right )P^{k}(1-P)^{(n-k)} \\= \left ( _{32}^{32}\textrm{} \right )0.54^{32}(0.46)^{(32-32)} \\= 0.54^{32} \\= 2.7327 \times 10^{-9}$
