Answer:

24 steps

Step-by-step explanation:

Given

Step\ 1 = 4

Step\ 2 = 3

Step\ 3 = 2

Required

The total number of experimental outcomes (n)

This calculated by multiplying the results in each step.

n = Step\ 1 * Step\  2 * Step\ 3

n = 4*3*2

n = 24

ASAP What is the volume of a sphere, to the nearest cubic inch, if the radius equals 3 inches? Use π = 3.14. A. 101 in³ B. 210 i
sesenic [268]

Answer: C. not given

Step-by-step explanation:

formula for volume of sphere: V=(4/3)πr³

V=(4/3)πr³

V=(4/3)(3.14)(3)³

V=(4/3)(3.14)(27)

V=113 in³

How to write the algebraic expression (2)(t) in words
Jlenok [28]

Answer:

"The number 8 multiplied by a number. "

"The product of 8 and a number"

"A number times the number 8"

Step-by-step explanation:

This is a long one,

You are going to write the expression using "key words"

Addition: sum, more than, plus, increase, add, older than.

Examples: 4+7

"The sum of 4 and 7"

"7 more than the number 4"

"The number 4 increased by 7"

Etc....

Subtraction: minus, less, subtract, decrease, younger than, and lowered.

Example: 9 - 2

"The number 9 decreased by 2"

"The number 2 younger than 7"

"The number 7 minus 2"

Etc....

Multiplication: times, product, twice, doubled, multiplied, and of.

Example: 4 × 5

"The number 4 multiplied by 5"

"The product of the numbers 4 and 5"

"5 times the number 4"

Etc...

Division: divided by and divided into and Quotient. Pay close attention to the order in which it is written.

Examples: 6 / 3

"The number 6 divided by 3"

"3 divided into the number 6"

Or

"The quotient of the numbers 3 into 6"

Ect...

Expressions with More Than One Operation example:

8y + 14 ...

You could say:

The sum of 8 times a number and 14.

When referring to unknown number i.e. x, y, n, v... you may refer to it a "a number"

Hmmm, best way I can describe it. :)

The scale used to make the model was 125 meters = 1 foot. 525 divided by 4.2 equals 125 meters.
The mode is 84 sheets of plywood tall.
4.2 feet = 50.4 meters
50.4 meters divided by 0.6 equals 84 sheets.

I arrive at a bus stop at a time that is normally distributed with mean 08:00 and SD 2 minutes. My bus arrives at the stop at an
Nimfa-mama [501]

Answer:

0.0485 = 4.85% probability that you miss the bus.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

When two normal distributions are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

In this question:

We have to find the distribution for the difference in times between when you arrive and when the bus arrives.

You arrive at 8, so we consider the mean 0. The bus arrives at 8:05, 5 minutes later, so we consider mean 5. This means that the mean is:

\mu = 0 - 5 = -5

The standard deviation of your arrival time is of 2 minutes, while for the bus it is 3. So

\sigma = \sqrt{2^2 + 3^2} = \sqrt{13}

The bus remains at the stop for 1 minute and then leaves. What is the chance that I miss the bus?

You will miss the bus if the difference is larger than 1. So this probability is 1 subtracted by the pvalue of Z when X = 1.

Z = \frac{X - \mu}{\sigma}

Z = \frac{1 - (-5)}{\sqrt{13}}

Z = \frac{6}{\sqrt{13}}

Z = 1.66

Z = 1.66 has a pvalue of 0.9515

1 - 0.9515 = 0.0485

0.0485 = 4.85% probability that you miss the bus.
