Answer:
the required probability is 0.0071
Step-by-step explanation:
Given the data in the question;
we have narrowed the possibilities down to 4 people, 5 weapons, and 7 rooms.
so total number of combinations for the narrowed down metrics is computed as follows;
using multiplication rule:
⇒ 4 × 5 × 7 = 140 ways
Now, the probability of making a random guess from our narrowed down choices as well as getting the guess correct will be;
⇒ 1 / 140
{ assuming that the narrowed down choices have within it the correction combination }
= 0.007142 ≈ 0.0071 { four decimal place }
∴ the required probability is 0.0071
Solve the equation below. Pls include work
28.10 = 15.5 + 5x
Answer:
2.52
Step-by-step explanation:
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
Answer:
x=2.52
Step-by-step explanation:
28.1 = 15.5 + 5x
(take 15.5 from both sides)
28.1-15.5=15.5-15.5+5x
12.6=5x
(Divide both sides by 5)
12.6/5=5x/5
2.52=x

Determine another point on the line given two points on the line. (-2, 9), (2, -1)
Answer:
(4,-6)
Step-by-step explanation:
1) First, let's find the slope of the line between the two points. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the x and y values of (-2,9) and (2,-1) into it, then solve:
[tex]m = \frac{(-1)-(9)}{(2)-(-2)}\\m = \frac{-1-9}{2+2} \\m =\frac{-10}{4} \\m = -\frac{5}{2}[/tex]
So, the slope of the line is [tex]-\frac{5}{2}[/tex].
2) Now, using that slope, let's find another point on the line. You can do this by drawing the two points on a graph (picture below). Now, remember that the slope is [tex]\frac{rise}{run}[/tex]. So, starting from any of the two points (I chose (2,-1), as seen below) count 5 units down, then 2 units to the right. This gives an answer, (4,-6).

find the area of each figure. if necessary, leave your answer in simplest form.
Answer:
256 ft^2
Step-by-step explanation:
area of rhombus = half of the product of the diagonals
diagonal 1 = 2 * 12.8 ft = 25.6 ft
diagonal 2 = 2 * 10 ft = 20 ft
area = d1 * d2/2 = 12.8 ft * 20 ft/2 = 256 ft^2

Consider the game where two dice, die A and die B, are rolled. We say that die A wins, and write A > B, if the outcome of rolling A is larger than that of rolling B. If both rolls result in the same number it is a tie.
a. find the porbability of a tie
b. find the probabilty that die A wins
Answer:
a) The probability of a tie is the probability of getting the same outcome in both dice.
First, we roll die A and we get a given outcome. (here the probability is 1 because there is no restriction)
Now we need to roll die B and get the same outcome, so here we have only one possible outcome out of 6, then in this case the probability is 1/6
The joint probability (the product of the individual probabilities) is: P = 1*(1/6) = 1/6
b) We want to find the probability that die A wins.
Here we need to analyze each possible outcome for die A.
Let's define:
pₙ = probability of winning given that the outcome is n.
If the outcome is a 1, die A can only lose or tie, then here:
p₁ = 0
If the outcome is a 2, then die A only wins if die B rolls a 1, (1 outcome out of 6)
Then the probability of winning is:
p₂ = 1/6
If the outcome is a 3, then die A wins if die B rolls a 1 or a 2, here we have two possible outcomes out of 6.
p₃ = 2/6
We already can see the pattern, if the outcome is a 4, we get:
p₄ = 3/6
if the outcome is a 5:
p₅ = 4/6
if the outcome is a 6:
p₆ = 5/6
The total probability is the sum of all the joint probabilities:
For each roll in dice A, the probability is 1/6 (the probability of getting a given outcome)
Then the probability that die A wins is:
P = (1/6)*p₁ + (1/6)*p₂ + ... = (1/6)*(p₁ + p₂ + p₃ + p₄ + p₅ + p₆)
P = (1/6)*(0 + 1/6 + 2/6 + 3/6 + 4/6 + 5/6)
P = (1/6)*(15/6) = 0.4167
Which expression is equivalent???
