Answer: The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours
Step-by-step explanation:
Unit rate is the ratio of the distance travelled o the time taken.
For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;
If distance = 9/8 miles and time = 5/6 hours
Hence the ratio that has a unit rate is 9/8 miles:5/6hours
If distance = 7 miles and time = 3/4 hours

What is a Square?A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90° angles. The characteristics of a rectangle and a square are somewhat similar, although a rectangle only has its opposite sides equal. As a result, a rectangle is only referred to as a square if its four sides are of the same length.
Given : side of the triangle = 16 inches
So, the perimeter of the triangle = 16+16+16
= 48 inches
Now, the wire is unbent and shaped into a square.
So, the length of the wire would be same.
Hence, we can say that:

determine whether the pair of functions and inverse functions f(x)=6x-15 and g(x)=1/6x+5/2
The pair of functions are inverses, as their compositions result in x.
What is the composite function of f(x) and g(x)?The composite function of f(x) and g(x) is given by the following rule:
(f ∘ g)(x) = f(g(x)).
It means that the output of the inside function serves as the input for the outside function.
If two functions are inverse, the composites f(g(x)) and g(f(x)) both result in x.
The composite functions for this problem are given as follows:
f(g(x)) = f(x/6 + 5/2) = 6(x/6 + 2.5) - 15 = x + 15 - 15 = x.g(f(x)) = g(6x - 15) = 1/6(6x - 15) + 2.5 = x - 2.5 + 2.5 = x.Hence they are inverses.

Consider the parabola represented by this equation.

Which features are features of the parabola?
0
opens down
opens to the left
directrix at y = ㅎ
vertex at (-1,0)
directrix at x =
02/00
HELPPPP MEEEW
Answer:
a) opens down
c) directrix at y = 1/8
d) vertex at (-1/2,0)
Step-by-step explanation:
Starting from the given equation:
4x^2 + 4x + 2y + 1 = 0
We can rearrange to obtain the standard form of the equation of a parabola:
2(y + 1/2) = -4(x + 1/2)^2 + 1
(y + 1/2) = -2(x + 1/2)^2 + 1/2
Comparing to the standard form:
(y - k) = a(x - h)^2
We can see that the vertex of this parabola is at the point (-1/2, -1/2).
Next, we can find the axis of symmetry by noting that the parabola is symmetric about a vertical line passing through the vertex. This line is given by:
x = -1/2
We can also determine whether the parabola opens upward or downward by looking at the sign of the coefficient a. In this case, a = -2, so the parabola opens downward.
The distance between the vertex and the directrix is given by |1/(4a)|. Therefore, the distance between the vertex (-1/2, -1/2) and the directrix is:
|1/(4(-2))| = 1/8
So the directrix of the parabola is the horizontal line y = 1/8.
Therefore, the correct options are:
a) opens down
c) directrix at y = 1/8
d) vertex at (-1/2,0)
The other options are incorrect:
b) The parabola does not open to the left.
e) The directrix is not a vertical line at x = -3/8.

A real estate agent has 19 properties that she shows. She feels that there is a 30 % chance of selling any one property during a
week. The chance of selling any one property is independent of selling another property. Compute the probability of selling at
least 5 properties in one week. Round your answer to four decimal places.
Answer: This is a binomial probability problem. Let X be the number of properties sold during a week, then X has a binomial distribution with parameters n=19 and p=0.3.
The probability of selling at least 5 properties is:
P(X ≥ 5) = 1 - P(X < 5)
To calculate P(X < 5), we can use the binomial cumulative distribution function or the normal approximation to the binomial distribution.
Using the binomial cumulative distribution function, we have:
P(X < 5) = Σ P(X = k) for k = 0 to 4
Using the formula for the binomial probability mass function, we get:
P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
= (0.7)^19 + 19(0.3)(0.7)^18 + 171(0.3)^2(0.7)^17 + 969(0.3)^3(0.7)^16 + 3876(0.3)^4(0.7)^15
Using a calculator or statistical software, we get:
P(X < 5) = 0.95044
Therefore, the probability of selling at least 5 properties in one week is:
P(X ≥ 5) = 1 - P(X < 5) = 1 - 0.95044 = 0.0496 (rounded to four decimal places).
So the probability of selling at least 5 properties in one week is approximately 0.0496 or 4.96%.

For someone with a foot length of 29 cm, identify the 95% prediction interval estimate of their height and write a statement interpreting that interval.
CORRECT ANSWER: 177 cm < y < 200 cm
The 95% prediction interval for the height is given by the inequality 177 cm < y < 200 cm.
The interpretation is that we are 95% sure that the height of a person with a foot length of 29 cm is greater than 177 cm and less than 200 cm.
What are the inequality symbols?The four inequality symbols, along with their meaning on the number line and the coordinate plane, are presented as follows:
> x: the amount is greater than x -> the number is to the right of x with an open dot at the number line. -> points above the dashed horizontal line y = x on the coordinate plane.< x: the amount is less than x. -> the number is to the left of x with an open dot at the number line. -> points below the dashed horizontal line y = x on the coordinate plane.≥ x: the amount is at least x. -> the number is to the right of x with a closed dot at the number line. -> points above the solid vertical line y = x on the coordinate plane.≤ the amount is at most x. -> the number is to the left of x with a closed dot at the number line. -> points above the dashed vertical line y = x on the coordinate plane.In this problem, the bounds of the interval are given as follows:
y > 177cm -> greater than 177 cm.y < 200 cm -> less than 200 cm.We have a compound inequality, hence both conditions have to be respected simultaneously.

The probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.
What is conditional probabilityConditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. The conditional probability P(A|B) occur only in the case of dependent events. It gives the conditional probability of A given that B has occurred.
P(F|G) = P(F∩G) / P(G)
P(F∩G) = Probability of happening of both F and G
P(F) = 199/600 = 0.3317
P(F∩G) = 79/600 = 0.1317
P(G) = 330/600 = 0.55
P(F|G) = 0.1317/0.55
P(F|G) = 0.2394.
Two events say A and B are independent if the probability of occurrence of one of them is not affected by the occurrence of the other, mathematical expressed as P(A ∩ B) = P(A) × P(B)
P(F) × P(G) = 0.3317 × 0.55
P(F) × P(G) = 0.1824
P(F∩G) is not equal to P(F) × P(G) from the data given.
Therefore, the probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.

Answer:
The median of the given data is 20. To find the median, arrange the data in numerical order, and then take the middle value. In this case, the data is arranged in numerical order as 0, 5, 10, 10, 12, 15, 15, 20, 25, 30, 30, 35, 35, 45, 60. The middle value is 20, which is the median.
Answer:
17.5
Step-by-step explanation:
To find the median of a set of numbers, we need to arrange the numbers in order from smallest to largest and then find the middle value.
In this case, the numbers in the set arranged in ascending order are:
0, 5, 10, 10, 12, 15, 15, 20, 25, 30, 30, 35, 35, 45, 60
There are 15 numbers in the set, which means that the middle value is the eighth number. Since there are two numbers in the middle (15 and 20), we take the average of these two numbers to find the median:
median = (15 + 20) / 2 = 17.5
Therefore, the median of the set of numbers is 17.5.

Write the equation of a rational function that has been reflected, shifted down 6, right 8, and stretched by a factor of 4.
To write the equation of a rational function that has been reflected, shifted 6 down, 8 to the right and stretched by a factor of 4, we have to start with the basic rational function which is:
f(x)= 1/xThe reflected function we multiply it by -1 resulting in: g(x)= -1/xHow to shift a function?To shift it down by 6, we must subtract 6 from the function, so we have:
h(x) = -1/x-6To shift the function to the right by 8, we substitute x for (x-8), finding this result:
i(x)= -1/(x-8)-6To stretch the function by a factor of 4, we have to multiply the denominator by 4, which will result in:
j(x)= -1/4(x-8))-6Therefore, the equation of the rational function will be:

Find the last digit of the product of 2001 * 2003 * 2005 * 2007 * 2009... * 2017 * 2019?
The last digit of the product is 5.
How did we get the value?To find the last digit of the product of these numbers, we only need to focus on the last digit of each number, since the other digits do not affect the last digit of the product. We can observe that every odd number has a last digit of 1, 3, 5, 7, or 9. Therefore, we only need to consider the last digit of every fifth odd number in the given sequence.
The last digit of 2001 is 1.
The last digit of 2003 is 3.
The last digit of 2005 is 5.
The last digit of 2007 is 7.
The last digit of 2009 is 9.
The last digit of 2011 is 1.
The last digit of 2013 is 3.
The last digit of 2015 is 5.
The last digit of 2017 is 7.
The last digit of 2019 is 9.
To find the last digit of the product of these numbers, we need to multiply all of these last digits together. We can group the digits into pairs that multiply to 1, and there is one 5 remaining. Multiplying all of these digits together gives:
1 * 3 * 5 * 7 * 9 * 1 * 3 * 5 * 7 * 9 * 5 = 5

find the perimeter of P and area of A of triangle JKL J(-5,-7),K(2,3),L(-1,-7)
Answer: To find the perimeter of triangle JKL, we need to find the length of each side and add them up. We can use the distance formula to find the length of each side:
Side JK = sqrt[(2 - (-5))^2 + (3 - (-7))^2] = sqrt[7^2 + 10^2] = sqrt[149]
Side KL = sqrt[(-1 - 2)^2 + (-7 - 3)^2] = sqrt[(-3)^2 + (-10)^2] = sqrt[109]
Side LJ = sqrt[(-1 - (-5))^2 + (-7 - (-7))^2] = sqrt[4^2] = 4
Therefore, the perimeter of triangle JKL is:
P = JK + KL + LJ = sqrt[149] + sqrt[109] + 4
To find the area of triangle JKL, we can use the formula:
A = 1/2 * base * height
We can choose any side as the base, and the corresponding height will be the perpendicular distance from the opposite vertex to the base. Let's choose side KL as the base. The height from vertex J to side KL is the perpendicular distance between J and the line containing KL. We can find this distance using the formula for the distance between a point and a line:
Area = 1/2 * KL * h
where h = |(2 - (-1))( -7 - 3) - (-5 - 2)(-1 - 3)| / sqrt[(-1 - 2)^2 + (-7 - 3)^2]
Simplifying the above expression, we get:
h = 24 / sqrt[109]
Therefore, the area of triangle JKL is:
A = 1/2 * KL * h = 1/2 * sqrt[109] * 24 / sqrt[109] = 12
So, the perimeter of triangle JKL is sqrt[149] + sqrt[109] + 4, and the area of triangle JKL is 12.

The reading on a water meter in April and May are 417.8 kl and 430.4 kl. If there is a basic charge of 23 pesos and the cost per kl is 20 pesos, how much is the billing for water consumption between the two months?
Answer:
the billing for water consumption between April and May is 275 pesos.
Step-by-step explanation:
To find the billing for water consumption between April and May, we need to calculate the difference in the water usage as measured by the water meter.
The difference between the readings in April and May is:
430.4 kl - 417.8 kl = 12.6 kl
To calculate the cost of this water usage, we need to multiply the volume of water by the cost per kl and then add the basic charge.
The cost of the water usage is:
12.6 kl x 20 pesos/kl = 252 pesos
Adding the basic charge of 23 pesos, the total billing for water consumption between the two months is:
252 pesos + 23 pesos = 275 pesos
Therefore, the billing for water consumption between April and May is 275 pesos.
Q.15. Bloom Pet Supplies makes a profit of $5.50 per bag on its line of dog food. Total expenses

at least $5,225 per day, which inequality represents how many bags of dog food d the store must
sell to meet their goal?
A. 5.50d 2,500 ≥ 5,225
B. 5.50 2,500d ≥ 5,225
C. 5.50d +2,500 ≥ 5,225
D. 5.50 +2,500d ≥ 5,225
Answer:
Let's use option C to represent the relationship between the number of bags of dog food sold and the profit made:
Profit per bag of dog food = $5.50
Total expenses per day = $2,500
The store wants to make a profit of at least $5,225 per day.
If d represents the number of bags of dog food sold, then the profit made can be represented as:
Profit = Revenue - Expenses
Revenue = Profit + Expenses
Revenue = $5.50d + $2,500
To make a profit of at least $5,225 per day, we can set up the following inequality:
$5.50d + $2,500 ≥ $5,225
Simplifying:
$5.50d ≥ $2,725
Dividing both sides by $5.50:
d ≥ 500
Therefore, the store must sell at least 500 bags of dog food per day to make a profit of at least $5,225 per day.
The correct inequality that represents this relationship is option C: 5.50d +2,500 ≥ 5,225.

If there is only one unique value of y for each value of x, then the equation 4x + y = 2x - 8 does not define y as a function of x.
The equation can be rewritten as y = mx + b, where m denotes the slope and b the y-intercept.
4x + y = 2x - 8
Taking 2x away from both sides:
2x + y = -8
When we take away 2x from both sides, we obtain:
