your water hose is leaking at a rate of 0.25 cups per hour. how many gallons did you hose leak in a full 24 hour day
Solution:
we are given that
water hose is leaking at a rate of 0.25 cups per hour.
We have been asked to find that
how many gallons did you hose leak in a full 24 hour day.
Since water hose is leaking at a rate of 0.25 cups per hour.
It mean the tank will leak by [tex] 0.25*4=1 \ Cup [/tex] in 4 Hours.
So in 24 Hours the tank will leak by [tex] \frac{24}{4}*1=6*1=6 \ Cups [/tex] .
As we know that 1 Gallon=16 Cups.
It mean in 24 Hours the tank leaked by [tex] \frac{1}{16}*6= 0.375 \ Gallon [/tex]
If your expenses are more than your income, then you have a positive net cash flow. Please select the best answer from the choices provided T F
Answer:
No, it is not a positive net cash flow. Because they are spending more than they even have which is creating debt.
Step-by-step explanation:
If your expenses are more than your income, then you have a positive net cash flow, which is false.
What is cash flow?The cash balance of liquid assets coming into and going out of a business is referred to as cash flow. Money spent and money received reflect inflows and outflows, respectively.
The cash flow is the difference between outflow and inflow.
Cash flow = out flow - inflow
If the value of the cash flow is negative that means the expense is more.
If the value of the cash flow is positive that means the income is more.
If your expenses are more than your income, then you have a positive net cash flow, which is false.

Karla is mowing her lawn. She knows 2/5 of the lawn before stopping for a snack. She resumes mowing after her snack and mows another 1/3 of her lawn before stopping. What total fraction of the lawn does Karla mow before lunch?
Karla mows a total of 11/15 of her lawn before lunch after adding the fractions 2/5 and 1/3 with a common denominator of 15.
The student's question has two parts where Karla mows her lawn in fractions, first 2/5 and then another 1/3. To find the total fraction of the lawn that she mows before lunch, these two fractions need to be added. However, since they do not have the same denominator, we first need to find a common denominator to combine these fractions properly.
The least common denominator (LCD) for 5 and 3 is 15. We convert the fractions to have this common denominator:
(2/5) becomes (6/15) after multiplying both the numerator and denominator by 3.(1/3) becomes (5/15) after multiplying both the numerator and denominator by 5.Now we add the fractions:
(6/15) + (5/15) = (11/15)
Thus, Karla mows a total of 11/15 of her lawn before lunch.
the width of a large, rectangular-shaped tree farm is 1.9 kilometers. The length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm ?
Answer:- The best estimate of the area of the farm is 8 kilometers.
Explanation:-
Given:- Width of the rectangular shaped tree farm= 1.9 kilometers
⇒Estimated width of the farm=2 kilometers [2 is the nearest integer to 1.9]
Length of the rectangular shaped tree farm=4.4 kilometers
⇒Estimated length of the farm=4 kilometers [4 is the nearest integer to 4..4]
To make estimates, we usually round the numbers the nearest integer.
Now, Estimated Area of the Farm= estimated width × estimated length
= 2×4 kilometers = 8 kilometers.
∴the best estimate of the area of the farm =8 kilometers.

Trigonometric Identities and Applications?
Trigonometric identities are equations that hold true for all permissible values of the involved variables. They are fundamental to many areas of mathematics and have applications in various fields such as physics and engineering.
Explanation:Trigonometric identities are equations that are true for all values of the variables where both sides of the equation are defined. They are fundamental to the study of mathematics, particularly in geometry, calculus and physics.
Some of the basic trigonometric identities include:
Reciprocal identities:sin = 1/csc θcos = 1/sec θtan = 1/cot θPythagorean identities:sin² θ + cos² θ = 11 + tan² θ = sec² θ1 + cot² θ = csc² θ...Trigonometric identities are widely used in solving trigonometric equations and proving other identities, and in many fields such as engineering, physics and computer science.

Answer with explanation:
Mean of this data set
[tex]=\frac{\text{sum of all the observation}}{\text{Total number of observation}}\\\\=\frac{30+37+37+41+22+69+45+64+51+22+63+31+64+65+25+51+26+48+28+49}{20}\\\\=43.4[/tex]

and if number of terms is even, divide number of terms by ,2 and then follow the procedure
[tex]=\frac{10^{th term}+11^{th term}}{2}\\\\=\frac{41+45}{2}\\\\=43[/tex]
To find the Outlier
[tex]Q_{1}=\frac{28+30}{2}=29,Q_{3}=\frac{51+63}{2}=57[/tex]
Interquartile range = 57 - 29=28
Data values are approximately equally distributed on both sides of median.
That is, 43-22=21, and ,69 -43=26
So,we can say that there will be no outliers.
Graph will be positively skewed.
Mean > Median
So,mean will be better measure of central tendency because, 43.4-22=21.4, and 69-43.4=25.6
Option A: There are no outliers.
And, Option C: The Mean is good measure of central tendency.

Question 10 an urn contains two white marbles and one black marble. a marble is drawn from the urn without replacement and put aside without my seeing it. then a second marble is drawn, and it is white. what is the probability that the unknown removed marble is white, and what is the probability that it is black?
Final answer:
The probability that the unknown removed marble is white is 1/2, and the probability that it is black is also 1/2. This is calculated by considering the outcomes of the draws, their probabilities, and the fact that drawing a white marble after another without replacement affects the outcomes.
Explanation:
The question involves calculating conditional probabilities in a scenario where marbles are drawn from an urn without replacement. Initially, the urn contains two white marbles and one black marble. A marble is drawn and set aside (its color unknown), and then a second marble is drawn, which is observed to be white. We are asked to find the probability that the first marble drawn was white, and the probability it was black.
To solve this, we consider the two possible scenarios for the first draw: drawing a white marble or drawing a black marble, and then drawing a white marble in the second draw. The probability of drawing white then another white (WW) equals, the probability of drawing a white marble first (2/3) multiplied by the probability of drawing the second white marble given the first was white (1/2). This gives (2/3)*(1/2) = 1/3. Alternatively, the probability of drawing a black then a white marble (BW) equals the probability of drawing a black marble first (1/3) multiplied by the probability of drawing a white marble given the first was black (2/2) = 1/3, simplifying to (1/3)*(1) = 1/3
To find the probability that the unknown marble is white, we see that both scenarios WW and BW result in drawing a white marble second, so we only need to calculate the probability of the WW scenario over the total probability of drawing a white marble in the second draw. This gives us 1/3 / (1/3 + 1/3) = 1/2. Therefore, the probability that the unknown marble is white is 1/2, and by complement, the probability it is black is also 1/2
