A traffic study has shown that the probability that 5 cars will pass over a small bridge in a 4-minute period is 0.16.What are the odds against exactly 5 cars passing over the bridge in that time?
Answers
A probability is the number of outcomes divided by the number of total outcomes.
An odd is given by a:b, in which a is the number of successes and b is the number of failures.
From the question, the probability of 5 cars will pass over a small bridge is 0.16
That means the total outcomes is 100 and the outcomes of successes are 16
Then to find the failures subtract 16 from 100
The failures = 100 - 16 = 84
Successes = 16
a = 16
Failures = 84
b = 84
Odds = a: b
Odds = 16: 84
Divide each term by 4 to simplify
Odds = (16/4): (84/4)
Odds = 4: 21
The answer is 4: 21

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Vince is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $51 for the meal, plus $5 per kilogram for the lobster he picks. At the second restaurant, Vince would pay $8 per kilogram for the lobster, in addition to $33 for the meal. Vince realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Vince pay for his dinner? What is the weight?Dinner would cost $ at either restaurant if Vince's lobster weighed kilograms.
Answers
Based on the given situation, if x is number of kilograms of lobster, you can write the following expressions:
51 + 5x cost in the first restaurant
33 + 8x cost in the second restaurant
In order to determine the value of x which makes the cost the same in both restaurants, equal the previous expressions and solve for x:
51 + 5x = 33 + 8x subtract 33 both sides and 5x subtract both sides
51 - 33 = 8x - 5x simplify
18 = 3x divide by 3 both sides
18/3 = x
6 = x
x = 6
Hence, the weight of the lobster is 6 kg.
The cost of the dinner is:
51 + 5(6) = 51 + 30 = 81
Hence, the cost of the dinner is $81

Answers
On (-∞, -2) ∪ (3,∞) f(x) is positive, On (-∞, -0.5) it is negative, On (0.5, ∞) it is increasing, in none of the intervals it is having positive concavity, On (-∞, ∞) it has negative concavity.
What X intervals are beneficial for fx?Seeing as how f (x) = 0 there. A function’s “positive regions” are those times when it is above the x-axis. Y-values that are positive are where it is (not zero).
The portions of a function that are below the x-axis are known as its negative regions.
How can I determine the time intervals where f is positive?You must first take the derivative, then make it equal to 0, and then determine which zero values the function is positive between in order to determine when a function is rising. In order to determine when the function is positive and, thus, rising, test values on all sides of these.

Write the equation of the line that is parallel to - 8x-6y = 5 that passes through thepoint (-9, 1)
Answers
First,we will find the slope of the line
Using 8x - 6y = 5
we will have to re-arrange the equation above to be in the slope-intercept form.
That is; it should be in the form y = mx + b
8x - 6y = 5
6y = 8x -5
y = 8/6 x - 5/6
slope = 8/6 = 4/3
In a parellel equation the slope are the same, hence the slope of our new equation is 4/3
Next, we find the intercept of the new equation;
Using the point (-9, 1) and slope(m) = 4/3
we will substitute into the equation below and then solve for b, where b is the slope of our new equation
y = mx + b
1 = 4/3 (-9) + b
1 = 4(-3) + b
1 = - 12 + b
add 12 to both-side of the equation
1+ 12 = b
13 = b
b= 13
Substituting m = 4/3 and b = 13 into the formula; y = mx+ b
y = 4/3 x + 13

Based on the table, what is the equation of the linear relationship in slope-intercept form?
y = 2x − 8
y = 2x + 8
y = −2x + 4
y = −2x − 4
Answers
Answer: y = 2x - 8
Step-by-step explanation:
When x = 0, y = -8. This is the y-intercept.
As x increases by 1, y increases by 2. This makes 2 the slope.
The equation for the linear relationship given, in slope-intercept form is y = 2x-8
What is slope-intercept form?The slope-intercept form of a linear equation is where one side contains just "y". So, it will look like: y = mx + b where "m" and "b" are numbers.
Given that, coordinates representing a linear relationship.
x → 0, 1, 3, 4
y → -8, -6, -2, 0
We need to find an equation for the given linear relationship in slope-intercept form,
Considering points, (0, -8) and (4, 0)
We know that, the equation of a line passing through, two points is given by,
y-y₁ = (y₂-y₁) / (x₂-x₁) (x-x₁)
Here, y₁ = -8, y₂ = 0, x₁ = 0, x₂ = 4
Therefore, the equation is =
y+8 = 8/4(x-0)
y+8 = 2x
y = 2x-8
Hence, the equation for the linear relationship given, in slope-intercept form is y = 2x-8

Select the correct answer. Jonathan has 30 chocolates. He gives some chocolates to his friend David. He then gives Sarah half the number of chocolates that he gave David and gives Lily two-thirds of what he gave David. After giving away the chocolates, Jonathan has 4 chocolates left. If the number of chocolates Jonathan gives David is x, which equation represents the situation? How many solutions does this equation have? A. x + 1 2 x + 2 3 x = 30 − 4 , which has no solution B. x + 1 2 x + 2 3 x = 30 , which has infinitely many solutions C. x + 1 3 x + 2 3 x − 4 = 30 , which has one solution D. x + 1 2 x + 2 3 x + 4 = 30 , which has one solution E. 1 2 x + 2 3 x = x − 4 , which has no solution
Answers
The solution to equation x+ 1/2x+2/3x+4= 30 and has one solution x = 12 which is the correct answer would be an option (D).
The no. of chocolates given to Sarah = 1/2 of x = x/2
Then Lily has two-thirds of what he has given David. Following the distribution of the chocolates,
The number of chocolates provided to Lily is equal to two-thirds of the number of chocolates given to David.
The number of chocolates given to Lily Equals 2/3 of x = 2x/3
Now, the total number of chocolates delivered to David, Sarah, and Lily
= x+x/2+2x/3
Here LCM of 2 and 3 is 6
The Total no. of chocolates given to David, Sarah, and lily
= (6x + 3x+ 4x)/6
The total number of chocolates distributed to David, Sarah, and Lily is 13x/6.
Jonathan had four chocolates left after giving them out.
The number of chocolates left with Jonathan equals the total number of chocolates given to David, Sarah, and Lily.
⇒ 4 = 30 - 13x/6
⇒ 4 + 13x/6 = 30
⇒ 13x/6 = 30-4 = 26
⇒ x = 26×6/13 = 2×6
⇒ x = 12
Hence, the equation which represents the given situation is 30 - 13x/6 =4

Solve 6x+3y=−1 for y
Answers
The required solution of the given equation 6x + 3y = −1 for y would be the value of equation y = -2x - 1/3.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The equation is given in the question below as:
6x + 3y = −1
We have to determine the solution of the equation 6x + 3y = −1 for y.
⇒ 6x + 3y = −1
Rearrange the terms of the variable in the above equation,
3y = - 6x - 1
Divided by 3 both sides of the equation to get
y = -2x - 1/3
Hence, the required solution of the given equation 6x + 3y = −1 for y would be the value of equation y = -2x - 1/3.

For the following, find f(2.1) and f(4).
Answers
Answer:
A
Step-by-step explanation:
Comment
The tricky part is f(4)
Log part
That is defined by log_2 which means that the base used for the log is 2.
We don't have log_2 on our calculators so you have to create it.
Substitute 4 for x
log_2 (4) = log_10(4)/ log_10 (2) Which your calculator can handle
log_2 (4) = Log(4)/ log(2) = 2
f(x) = 1/2 x^2
x = 2.1
Only answers a and b are correct, but which one is right? 2.1 is between 2 and 4. So you choose f(x) = 1/2 x^2
1/2 2.1^2 = 1/2 4.41 = 2.205
Answer
A
Answer:
(a) f(2.1) = 2.205 and f(4) = 2
Step-by-step explanation:
You want to evaluate a piecewise-defined function to find f(2.1) and f(4).
DomainThe first step in evaluating a piecewise defined function is to match the argument value with the appropriate domain.
for f(2.1), you want to use the definition for the domain 2 < x < 4for f(4), you want to use the definition for the domain 4 ≤ x < 8Function evaluationOnce you have identified the function you are evaluating, substitute the argument for the variable and carry out the arithmetic in the usual way.
f(2.1) = 1/2(2.1)² = 1/2(4.41) = 2.205f(4) = log₂(4) = log₂(2²) = 2The desired function values are f(2.1) = 2.205 and f(4) = 2.
