Answer plz Nina has a collection of 20 seashells she wants to display in rows List all of the ways that nina can display her she

Galina-37 [17]

Nina has 20 seashells, and she needs to display them in rows with equal number of seashells in each row.

She wants to know what are the different possible ways to do that

This is a problem of factorization. We need to determine all the factors for the number of seashells she has

Factorizing 20:

20 = 1 × 2 × 2 × 5

Now, dividing 20 by each factor, we will get to know the possible ways in which she can arrange the seashells

Starting with the smallest factor, i.e. 1 and moving on to larger factors

20 ÷ 1 = 20. So she can have 1 row, with 20 seashells

20 ÷ 2 = 10. She can have 2 rows, with 10 seashells in each row

20 ÷ 4 = 5. She can have 4 rows, with 5 seashells in each row

20 ÷ 5 = 4. She can have 5 rows, with 4 seashells in each row

20 ÷ 10 = 2. She can have 10 rows, with 2 seashells in each row

20 ÷ 20 = 1. She can have 20 rows, with 1 seashell in each row

So there are total of 6 ways to arrange the seashells.

How can I simpliy |-15| + |-26|?

deff fn [24]

A negative number inside of | | will become positive when taken out of it.

If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will

aleksandrvk [35]

Answer:

$P(T\ n\ S) = \frac{1}{14}$

Step-by-step explanation:

*Missing Part of the Question*

4 stars

5 triangles

3 circles

3 squares

Required

Determine the probability of triangle being first then square being second

$Total = 4 + 5 + 3 + 3$

$Total = 15$

Represent the triangle with T and square with S

So, we're solving for P(T n S)

$P(T\ n\ S) = P(T) * P(S)$

Solving for P(T)

$P(T) = \frac{n(T)}{Total}$

$P(T) = \frac{5}{15}$

Solving for P(S)

The question implies a probability without replacement;

Hence Total has now been reduced by 1

Total = 14

$P(S) = \frac{n(S)}{Total}$

$P(S) = \frac{3}{14}$

Recall that

$P(T\ n\ S) = P(T) * P(S)$

$P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}$

$P(T\ n\ S) = \frac{15}{15 * 14}$

$P(T\ n\ S) = \frac{1}{14}$

Hence, the required probability is

$P(T\ n\ S) = \frac{1}{14}$
