Team A and Team B are competing against each other in a game of tug-of-war. Team A, consisting of 3 males and 3 females, decides

saul85 [17]

Answer: Team A will choose one of 36 possible lineups.

Step-by-step explanation: Given that Team A and Team B are playing the game of tug-of-war.

Team A has 3 males and 3 females that decides to line up male, female, male, female, male, female.

We are to find the number of possible lineups that Team A can make.

According to the given information,

number of options for the first position = 3,

number of options for the second position = 3,

number of options for the third position = 2,

number of options for the fourth position = 2,

number of options for the fifth position = 1

and

number of options for the sixth position = 1.

Therefore, the number of possible lineups by Team A is

$n=3\times3\times2\times2\times1\times1=36.$

Thus, Team A will choose one of 36 possible lineups.

How can you write the equation for a linear function if you know only two ordered pairs for the function?

Vinvika [58]

1. m
2. One set of ordered pairs
3. b

To show why this is, I’m going to explain how to write the equation for a linear function with two random sets of ordered pairs - (1,0) and (5, 8).

First, find the slope. The formula for slope is m = (y2 - y1)/(x2-x1) where m is the slope and (x1, y1) and (x2, y2) are two sets of points.

This is why #1 is m. M is the letter used when finding slope.

To find m, I plug in the two sets of ordered pairs.

m = (8-0)/(5-1)
m = 8/4
m = 2

An equation for a line (linear function) is written in something called slope-intercept form. It looks like y = mx + b. m is the slope and b is the y-intercept (number y equals when x = 0). If m = 3 and b = 1, the equation would be y = 3x + 1.

Here, you have just solved for m and know it equals 2. Plug that value in for m.

y = 2x + b

To solve for b, plug one ordered pair in for x and y. I will use (1,0)

0 = 2(1) + b
0 = 2 + b
-2 = b

Now that you know b = -2, plug that in for b.
y = 2x - 2. Now you have the equation fo the line.

if a pair of standard dice are rolled what is the probability that one of the dice will be a 3 and the other a 4?

satela [25.4K]

Answer:

<h2> ¹/₁₈ = 0,0(5)</h2>

Step-by-step explanation:

6•6 = 36 - all possibilities in a roll of two dices

3&4 or 4&3 - two possibilites

Probability that one of the dice will be a 3 and the other a 4:

$\frac2{26}=\frac1{18}=0,05555....=0,0(5)$
