What is the perimeter of a triangle with the given side lengths?

Mathematics

saul85 [17]3 years ago
5 0

The perimeter of any shape is the distance all the way around it.

For a triangle, it's the sum of the three side lengths.

I would normally copy them into my answer and then add them up.
But you've set them up in such a beautiful table in the question,
you can just look at that list and add them up.

Add up all the x's :     x + x + x = 3x

Add up all the plain numbers:  -3 + 2 + 4 = 3

There's your perimeter . . . . .  3x + 3 .

How can a graph help you determine an exponential model is appropriate for a data set? Explain ​
I am Lyosha [343]

The graph of the data set will help you to understand if the data is displayed in the form of an exponential model. Example: if the data (when graphed) is similar in shape and growth to that of the graph of f(x)=e^x, then it could be deemed helpful.

A database system assigns a 32-character ID to each record, where each character is either a number from 0 to 9 or a letter from
EastWind [94]

Answer:

0.948

Step-by-step explanation:

Given that:

Number of character ID = 32

Numbers = 0 - 9 = 10

Alphabets = A - F = 6

Likelihood of each number or alphabet is equal

Probability that atleast 16 characters in the ID are numbers

Probability of success (p) = required outcome / Total possible outcomes

p = 10/(10 + 6) = 5/8

P(at least 16 numbers), similar to 1 - p(at most 15)

Using the specified calculator :

Binomcdf(number of trials, p, 15) = 0.0520

1 - 0.0520 = 0.948
