Pepper jackie purchased 3.5 pounds of jelly beans for 1.19 per pund. How much did she spend on jelly beans, to the nearest cent
Pani-rosa [81]

Answer:

416.5 cent Pepper jackie  spend on jelly beans .

Step-by-step explanation:

As given

Pepper jackie purchased 3.5 pounds of jelly beans for $1.19 per pound.

Thus

$1.19 = 1 pound

Cost of 3.5 pounds of jelly beans = 1.19 × 3.5

                                                       = $4.165

Therefore the cost of 3.5 pounds of jelly beans is  $4.165 .

As 1 dollar = 100 cent

 $4.165  = 4.165 × 100

              = 416.5 cent

Therefore 416.5 cent Pepper jackie  spend on jelly beans .

2. The probability that a car will come to a complete stop at a particular stop sign is 0.4. Assume that the next four cars
kodGreya [7K]

Answer:

P(X = 0) = 0.1296

Step-by-step explanation:

This can be solved using the binomial distribution because the cars arriving at the stop are independent of each other. This means we will use:

P(X = x) = \binom{n}{x} p^{x} q^{n - x}

Where p is the probability of success, q = 1 - p is the probability of failure and n is the number of cars sampled.

p = 0.4

q = 0.6

n = 4

Therefore,

P(X = 0) = \binom{4}{0} 0.4^{0} 0.6^{4}

This is equal to

P(X = 0) = 1 \times 1 \times 0.1296

P(X = 0) = 0.1296
