Suppose 2.5 liters of water come out of a faucet each minute. For how many minutes was the faucet on if 38.5 liters of water came out?
Answer:
15.4 min
Step-by-step explanation:
rate = liters/min = 2.5 l/min
time = liters/rate = 38.5 l / (2.5 l/min) = 15.4 min
The graph of the function g(x) = a |x| includes the point (1, 16). What is another point on the graph of the function? What is the value of a?
The graph of the function g(x) = a |x| includes the point (1, 16). (-1, 16) is another point on the graph of the function.
What is function?Exactly one element of Y is assigned to each element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and co-domain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.
Given that,
g(x) = a |x|
In a absolute value graph the value of y is the same in -x and x.
Then if the coordinates (x,y) one point is (1, 16), the graph have another point in (- 1, 16).
To find the value of a you use one of the points (x,y) in the general form of absolute value:
( 1 , 16) x = 1 f(x) = y = 16
16 = a | 1 |
As, |±a| = a
we get:
16 = a . 1
then, a = 16
The equation for the graph with points (1 , 16) and ( -1, 16) is:
g(x) = 16 |x|
a = 16

Answer:
27 and 13
Step-by-step explanation:
let the second number be x then the first number is x - 14
sum the 2 numbers and equate to 40
x - 14 + x = 40
2x - 14 = 40 ( add 14 to both sides )
2x = 54 ( divide both sides by 2 )
x = 27
x - 14 = 27 - 14 = 13
the first number is 27 and the second number is 13

She wants to find the distance from barn B to the north end of pipe 2. The distance from the barn
to the south end of pipe 1 is 111 ft, the distance from there to the south end of pipe 2 is 23 ft, and
the distance from the barn to the north end of pipe 1 is 127 ft. How far is barn B from the north
end of pipe 27 Round your answer to the nearest foot. The map is not drawn to scale. M
The distance of barn B from the north end of pipe 27 is 258 ft to the nearest foot.
How to calculate distance?Let's call the distance from Barn B to the north end of pipe 2 as "d".
The distance from the barn to the south end of pipe 1 is 111 ft, the distance from there to the south end of pipe 2 is 23 ft, and the distance from the barn to the north end of pipe 1 is 127 ft.
So the total distance from barn B to the south end of pipe 2 is 111 + 23 = 134 ft.
Since the distance from barn B to the north end of pipe 1 is 127 ft, then the distance from the north end of pipe 1 to the north end of pipe 2 is d - 127 ft.
Since the distance from barn B to the south end of pipe 2 is 134 ft, then the distance from the south end of pipe 2 to the south end of pipe 1 is 134 - d ft.
Now, two right triangles with legs (d - 127) ft and (134 - d) ft.
By the Pythagorean Theorem, we have: (d - 127)² + (134 - d)² = 25²
Expanding and simplifying the equation gives us:
d² - 260d + 17296 = 625
d² - 260d + 16671 = 0
Using the quadratic formula:
d = (260 ± √(260² - 4 x 16671)) / 2
d = (260 ± √(677600 - 66768)) / 2
d = (260 ± √(61032)) / 2
d = (260 ± 246.9) / 2
d = 258 ± 123.5
So, the distance from barn B to the north end of pipe 2 is 258 ft or 381 ft.
Since the question asks to round the answer to the nearest foot, we can conclude that the answer is 258 ft.

At a particular restaurant, each onion ring has 40 calories and each pizza roll has 80
calories. A combination meal with pizza rolls and onion rings is shown to have 800
total calories and 4 more pizza rolls than onion rings. Graphically solve a system of
equations in order to determine the number of onion rings in the combination meal,
x, and the number of pizza rolls in the combination meal, y.
As a result, the combo meal includes 4 onion rings and 8 pizza buns.
What is equation?An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.
Here,
Let x be the number of onion rings in the combination meal and y be the number of pizza rolls. We can write the following system of equations to represent the given information:
40x + 80y = 800 (the total calories of the meal)
y = x + 4 (the number of pizza rolls is 4 more than the number of onion rings)
We can substitute the second equation into the first equation to solve for x:
40x + 80(x + 4) = 800
40x + 80x + 320 = 800
120x = 480
x = 4
We can use this value to find y:
y = x + 4 = 4 + 4 = 8
So, the combination meal contains 4 onion rings and 8 pizza rolls.

From a sample with n=12, the mean number of television per household is 3 with a standard deviation of 1 television. Using Chebychev Theorem,determine at least how many of the households have between 1 and 5 televisons
Answer:
9
Step-by-step explanation:
Chebyshev's Theorem states that for any given sample, at least 1 - 1/k^2 of the data falls within k standard deviations from the mean.
Let's use k = 2. Then, at least 1 - 1/2^2 = 1 - 1/4 = 3/4 of the households should have between 3 - 2 = 1 and 3 + 2 = 5 televisions.
So, at least 12 * 3/4 = 9 of the households in the sample have between 1 and 5 televisions.
Zachary purchased a computer for $1,800 on a payment plan. Three months after he purchased the computer, his balance was $1,440. Six months after he purchased the computer, his balance was $1,080. What is an equation that models the balance y after × months?
The equation __________ models the balance y after x months.
(Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation. Do not include the $ symbol in your answer.)
Answer:
Equation: y = 1800 - 120x
Step-by-step explanation:
y = 1800 - mx Where x = months after purchase of computer
y = balance remaining
1800 = y-intercept because this is your initial balance remaining as it is the actual price of the computer.
The coefficient of ‘m’ will be negative for this equation because the value of y decreases as x increases. (NOTE: y is NOT indirectly proportional to x as the line of the equation does not pass through the origin)
Next step is to determine 'm’:
m = slope of equation
Two sets of x and y values have been provided:
[tex](x_{2}, y_{2}) = (3, 1440)[/tex]
[tex](x_{3} ,y_{3})= (6, 1080)[/tex]
Use any set and substitute in the slope-intercept equation to determine the value of m:
1080 = 1800 - 6m
All the like terms are brought together and m needs to be isolated:
6m = 1800 - 1080
6m = 720
m = [tex]\frac{720}{6}[/tex]
m = 120
Therefore:
y = 1800 - 120x

Justify your answer.
The probability that the postman is never bitten by a dog is equal to the product of all qi's from i=1 to infinity, which is equal to (1-α)^∞. This is equal to 0 since α is a positive number.
The probability that the postman is never bitten by a dog is given by P(X > n), where X is the number of days until the postman sustains his first bite. This probability can be expressed as the product of all of the qi's from i=1 to n, which is equal to (1-α)^n, where qn = α for all n, and 0 < α < 1. The probability that the postman is never bitten by a dog is equal to the product of all qi's from i=1 to infinity, which is equal to (1-α)^∞. Since 0 < α < 1, (1-α)^∞ is equal to 0, meaning that the probability that the postman is never bitten by a dog is 0. This is because as n increases, the probability that the postman is not bitten by a dog on Day n decreases, and as n approaches infinity, it approaches 0.
