How many ways can we arrange 3 tulips, 2 yellow roses, and 8 lilies to form a border around a garden?

Elina [12.6K]

Answer:

The mentioned flowers can be arranged in 48 different ways.

Step-by-step explanation:

To determine in how many ways the mentioned flowers can be arranged (3 tulips, 2 yellow roses, and 8 lilies), all the variables must be multiplied together, and the result will be the number of possibilities for organizing them. Thus, the resolution of this question is the following:

3 x 2 x 8 = X

6 x 8 = X

48 = X

Therefore, the mentioned flowers can be arranged in 48 different ways.

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin

Gala2k [10]

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am = 30, so $a = 0, b = 30$

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

$P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333$

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Find the LCD of the pair of expressions.

Lisa [10]

The correct answer is D.

The LCD, least common denominator, is the smallest denominator that both denominators will go into. The LCD of 5 and 7 will be 35; the variable portion will be b³c, since that is the smallest thing the second fraction can go into.

This gives us a denominator of 35b³c.
