how many 80 oz in a gallon
There are 0.625 (or approximately 5/8) gallons in 80 fluid ounces. It's worth noting that the conversion factor between fluid ounces and gallons can vary depending on the system of measurement used
There are 128 fluid ounces in a gallon in the US customary system of measurement. Therefore, to find out how many 80-ounce containers are in a gallon, you can use the following formula:
number of 80-ounce containers in a gallon = 128 / 80
Simplifying this expression, we can perform the division:
number of 80-ounce containers in a gallon = 1.6
This means that there are 1.6 (or approximately 1 and 3/5) 80-ounce containers in a gallon.
Alternatively, you can convert the 80 ounces to gallons using the following formula:
number of gallons in 80 fluid ounces = 80 / 128
Again, simplifying this expression, we can perform the division:
number of gallons in 80 fluid ounces = 0.625

Express the confidence interval 0.039 < p < 0.479 in the form p± E. A. 0.22 ±0.5 B. 0.259 ±0.5 C. 0.259 ±0.44
D. 0.259 ±0.22
Answer:
Step-by-step explanation:
To express the confidence interval 0.039 < p < 0.479 in the form p ± E, we need to find the midpoint of the interval and half of the width.
The midpoint of the interval is the average of the lower and upper bounds:
Midpoint = (0.039 + 0.479) / 2 = 0.259
The width of the interval is the difference between the upper and lower bounds:
Width = 0.479 - 0.039 = 0.44
Half of the width is obtained by dividing the width by 2:
Half Width = 0.44 / 2 = 0.22
Therefore, the confidence interval 0.039 < p < 0.479 can be expressed as:
p ± E = 0.259 ± 0.22
So, the correct option is:
D. 0.259 ± 0.22

Given segment CB is parallel to segment ED. Find BD.
The length of segment BD on the triangle is given as follows:
BD = 12.5 units.
How to obtain the length of segment BD?The theorem used to solve this problem is given as follows:
A line parallel to one side of a triangle divides the other two proportionately.
The parallel lines in this problem are given as follows:
BC and DE.
Then the proportional segments are given as follows:
AB and AC.
Thus the proportional relationship that relates these side lengths is given as follows:
(x - 2)/3 = (x + 3)/5.
Applying cross multiplication, the value of x is obtained as follows:
3x + 9 = 5x - 10
2x = 19
x = 19/2
x = 9.5.
Then the length of BD is obtained as follows:
BD = x + 3 = 9.5 + 3 = 12.5.

Round 7.6258 to the thousandths place
Answer:
7.626
Step-by-step explanation: thousandths place is 3 from the decimal point
\(7.6258\) rounded to the nearest thousandths would be written as:
\(\fbox{7.626}\)
The 5 in the thousandths place would be rounded to 6 because the digit in the ten thousandths place is 8. If the digit is over 5, it is rounded away from zero.
If f(x) = 5x - 6, which of these is the inverse of f(x)?
A. f^-¹(x) = x/5 +6
B. f^-¹(x) = x/5 -6
C. f^-¹(x) = x+6/5
D. F^-¹(x) = x-6/5
To find the inverse of a function, we need to swap the positions of x and y and then solve for y. In other words, we replace f(x) with y and then solve for x.
So, let's start by swapping x and y in the function f(x) = 5x - 6:x = 5y - 6
Next, we'll solve this equation for y:
x + 6 = 5y
y = (x + 6)/5
Therefore, the inverse of f(x) is f^-1(x) = (x + 6)/5, which is option C.In the diagram, PN is the perpendicular bisector of AB and is also the angle bisector of ∠CPD. If m∠CPD = x, which quantity is equal to sin∠DPB?

scores on an iq test are normally distributed. the test is designed so that the mean is 100 and standard deviation is 15. (a) what percentage of the population has an iq above 120?
From the normal distribution it is calculated that 9.18% of people has an iq over 120.
Normal distributions are crucial to statistics because they are widely used in the natural and social sciences to represent real-valued regressors with unknown distributions.
Some of their significance can be attributed to the central limit theory. This claim states that, in some cases, the average of many samples (observations) of a stochastic process with limited mean and variance constitutes itself as a random variable, whose distribution merges to a normal distribution as the number of samples increases.Because of this, the distributions of physical values, such as error margins, which are expected to be the sum of many independent events, are frequently near to normal.We have to find P( X > 120 )
Thus find z score for x =120
\(z=\frac{x-\mu}{\sigma}=\frac{120-100}{15}=\frac{20}{15}=1.33\)
Thus we get:
P(X>120) = P(Z>1.33)
P(X>120) = 1 - P(Z<1.33)
P( Z < 2.67) = 0.9082
Thus
P(X>140) = 1 - P(Z<2.67)
P(X>140) = 1 - 0.9082
P(X>140) = 0.0918
Percentage = 9.18%
Therefore 9.18% of people has an iq over 120.

Use the number line below to find the midpoint of segment AB & segment BD. midpoint of segment AB: midpoint of segment BD: Please help ASAP NOW
Answer:
midpoints of segments AB and BD are (-3, 0) and \((\frac{7}{2},0)\).
Step-by-step explanation:
By using number line given in the figure attached,
Coordinates of the extreme ends of the segment are A(-7, 0) and B(-1, 0).
Midpoint of segment AB = \((\frac{-7-(-1)}{2}, 0)\)
= (-3, 0)
Coordinates of extreme ends of BD are B(-1, 0) and D(6, 0).
Midpoint of segment BD = \((\frac{6+1}{2}, 0)\)
= \((\frac{7}{2},0)\)
Therefore, midpoints of segments AB and BD are (-3, 0) and \((\frac{7}{2},0)\).

What would be the solution to the system of equations: y= -x + 4 y= 3x
Answer:
Step-by-step explanation:
The value of y is given in equation 2
Putting value of y = 3x in equation 1
Y = - x + 4
3x = - x + 4
Bringing like terms on one side
3x + x = 4
4x = 4
x = 4/4 = 1
Now putting value of x = 1 in equation 2
Y = 3x
Y = 3(1) = 3

a compound melts at 120°–122°c on one apparatus and at 128°–129°c on another. unfortunately, neither apparatus is calibrated. how might you check the identity of your sample without calibrating either apparatus?
It is always best to calibrate the apparatus or use a different method to confirm the identity of the sample.
One possible way to check the identity of the sample without calibrating either apparatus is to perform a melting point depression experiment using a known impurity. This method works on the principle that adding an impurity to a compound will lower its melting point.
To do this, we can mix a small amount of the suspected compound with a known impurity that has a melting point close to the melting point range of the suspected compound. We can then measure the melting point range of the mixture using both apparatus.
If the mixture melts at a lower temperature range than the suspected compound as measured by both apparatus, then it is likely that the suspected compound is the pure compound, since the impurity has caused a depression in the melting point range. On the other hand, if the mixture melts at a similar temperature range as the suspected compound as measured by both apparatus, then it is likely that the suspected compound is not pure.
It is important to note that this method is not foolproof and may not work well if the impurity has a significantly different melting point than the suspected compound or if the impurity is present in too low of a concentration to cause a significant depression in the melting point range. Therefore, it is always best to calibrate the apparatus or use a different method to confirm the identity of the sample.

in how many ways can eight different books be distributed to 12 children if no child more than one book
The number of ways to distribute the books is calculated using the concept of permutations, specifically the concept of selecting a subset without replacement. The answer is 199,584 possible ways.
In this scenario, we have 12 children and 8 different books. Since each child can receive at most one book, we can view this problem as selecting a subset of 8 books from the total set of 12 children.
To calculate the number of ways to distribute the books, we use the concept of permutations. Specifically, we use the formula for selecting a subset without replacement, denoted as nPr, where n is the total number of children and r is the number of books to be distributed.
Using this formula, we calculate 12P8, which is equivalent to 12!/(12-8)!. Simplifying this expression, we have 12!/4!. Evaluating the factorials, we find 12! = 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 and 4! = 4 × 3 × 2 × 1.
By dividing 12! by 4!, we obtain 199,584, which represents the number of ways to distribute the 8 different books to the 12 children, ensuring that each child receives at most one book.
In summary, there are 199,584 possible ways to distribute the eight different books among 12 children, with each child receiving at most one book. This is calculated using the concept of permutations, specifically the formula 12P8 = 12!/4!.

3x + 8 > 50 ( subtract 8 from both sides )
3x > 42 ( divide both sides by 3 )
x > 14

The area is calculated by multiplying length and breadth , then
3(4x - 2) < 138 ( divide both sides by 3 )
