Hallie can use the equation p = 4l + 4w + 4h to determine the sum of the lengths of the edges of a rectangular prism. She begins

Answer:

128/15 minutes or 8.5 minutes

Step-by-step explanation:

Utilizing the unitary method,

The duration to paint 5/8 of the wall is 16 minutes.

Consequently, the time to paint the entire wall is calculated as 16 × 8/5.

Thus, the time required to paint 1/3 of the wall amounts to 16 × 8/5 × 1/3.

Answer:

Carmen's estimate is too low, since rolling 200 times results in a total of 50.

Step-by-step explanation:

Initially, we will define the sample space for this scenario.

The sample space is Ω = {1,2,3,4,5,6,7,8}

For the event A: "Rolling an 8-sided die to get a multiple of 4"

The probability for event A is

This is because there are two multiples of 4 (4 and 8) out of a total of eight numbers (1 through 8).

Next, considering the random variable X: "Total count of multiples of 4 if she rolls an 8-sided die 200 times"

X can be described as following a Binomial distribution.

X ~ Bi (n,p)

X ~ Bi (200,)

Where n is the number of rolls and p is the probability of success, defined as rolling a multiple of 4.

The mean for this variable is

Thus, we conclude that Carmen's prediction is low, as rolling 200 times yields 50.
