Beth gets a sum of 5 when she rolls two fair number cubes. What is the probability that one of the fair number cubes is a 1?
Answers
Using it's concept, it is found that there is a 0.5 = 50% probability that one of the fair number cubes is a 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The outcomes of the pair of cubes that result in a sum of 5 are as follows:
(1,4), (2,3), (3,2), (4,1).
Of those 4 outcomes, 2 involve a number 1, hence the probability is given by:
p = 2/4 = 0.5.

Gabrielle needs to rent a car while on vacation. The rental company charges $19.95, plus 15 cents for each mile driven. If Gabrielle only has $40 to spend on the car rental, what is the maximum number of miles she can drive?
Round your answer down to the nearest mile.
Answers
Answer:
133 miles
Step-by-step explanation:
The limited budget gives rise to an inequality that can be solved for the maximum number of miles.
__
setupThe rental cost for m miles will be the sum of the fixed charges and the product of the mileage charge and the number of miles.
cost = 19.95 +0.15m
We want this to be no greater than 40, so we have the inequality ...
40 ≥ 19.95 +0.15m
solutionThis two-step inequality can be solved in the usual way:
20.05 ≥ 0.15m . . . . . step 1, subtract 19.95 from both sides
133.667 ≥ m . . . . . . . step 2, divide by the coefficient of the variable
The maximum whole number of miles Gabrielle can drive is 133.

Arun took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4 plus $4.25 per mile. The total fare was $110.25, not including the tip. How many miles was the taxi ride?
Answers
Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.
So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.
So if you travel for m miles, the cost equation is:
C(m) = $4.10 + $0.50*m
Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:
$9.60 = C(m) = $4.10 + $0.50*m
$9.60 = $4.10 + $0.50*m
$9.60 - $4.10 = $0.50*m
$5.50 = $0.50*m
$5.50/$0.50 = m = 11
This means that Arun traveled 11 miles in the taxi.
The Eva traveled 25 miles in the taxi.
It is required to find how many miles was the taxi ride.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
The taxi company charged a pick-up fee of $4 plus $4.25 per mile.
The total fare was $110.25.
The cost equation is:
C(m) = $4 + $4.25*m
Now, we know that for Eva the total fare (total cost) was $110.25, then we need to solve:
$110.25 = C(m) = $4 + $4.25*m
$110.25-$4=$4.25*m
$106.25=$4.25*m
m =25
Therefore, the Eva traveled 25 miles in the taxi.

The discriminant is:
[tex]\Delta = b^2 - 4ac[/tex]
The solutions are as follows:
If [tex]\mathbf{\Delta > 0}[/tex], and it has 2 x-intercepts.If [tex]\mathbf{\Delta = 0}[/tex], it has 1 x-intercept.If [tex]\mathbf{\Delta < 0}[/tex], it has no x-intercepts.In this problem, the function is given by:
f(x) = (x + 5)² - 3.
In standard form:
f(x) = x² + 10x + 22.
We want to find coefficient k for which the function has [tex]\Delta < 0[/tex], then:
f(x) = x² + 10x + 22 + k.
The coefficients are a = 1, b = 10, c = 22 + k, hence:

Answers
Using the Empirical Rule, it is found that the mean is of 64 inches and the standard deviation is of 3.2 inches.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.The normal distribution is symmetric, hence the mean is given by:
M = (57.6 + 70.4)/2 = 64.
57.6 is two standard deviations below the mean, hence the standard deviation is found as follows:
57.6 = 64 - 2s.

Two balls are drawn without replacement from a box containing 2black and 3 red balls. What is the probability of drawing a black ball on the second draw? Draw a tree diagram
Answers
The probability that the second ball drawn is black is 4/10 = 2/5
How to find the probability?
There are two cases. The case where the first ball is red is the first one.
The probability of drawing a red ball is equal to the quotient between the number of red balls and the total number of balls.
p = 3/5
Then, the probability of drawing a black ball in the second attempt is computed in the same way, but because we already drew a ball, now the total number of balls is 4, so we have:
q = 2/4 = 1/2.
So the joint probability is:
P = (3/5)*(1/2) = 3/10.
Then we have the case where both balls are black, the probabilities now are:
p = 2/5
q = 1/4
So the joint probability is:
P = (2/5)*(1/4) = 1/10
The total probability is the sum of the two above:
probability = 3/10 + 1/10 = 4/10.
The probability that the second ball drawn is black is 4/10 = 2/5
