if x is an integer it does not show the median of the 5 numbers to be greater than the average of the 5 numbers
What is a median in math?The value that, when a dataset is arranged, falls exactly in the center is the median. It is a measure of central tendency that distinguishes between the values' lowest and maximum 50%. Depending on whether you have an odd or an even number of data points, the processes for calculating the median change.
How do you find the median?Finding the middle number requires sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers). Example: When the numbers are arranged (1, 4, 7), the number 4 lies in the center, making it the median of 4, 1 and 7.
(1) x must be higher than one or three. It will be the median if it is 8 or fewer.
Consequently, if x = 7, then the list is 1, 3, 7, 8, 12, and median is 7, while the average is 31/5, which equals 6.2, and the answer is YES.
The list is 1, 3, 8, 8, 12, and the median is 8 if x = 8. Average = 32/5 = 6.4; if x = REALLY BIG, the list is 1, 3, 8, 12, and x; and the median is 8; the answer is YES. The answer to the question is NO since the average is REALLY BIG.
insufficient
(2) According to the aforementioned findings, x must be at least 9.
Depending on the amount of x, the list is either 1, 3, 8, x, 12, or 1, 3, 8, x.
The median and mean expressions are the same, regardless of whether order is appropriate:
Mean (average): 8 median = (1 + 3 + 8 + 12 + x)/5 = (24 + x)/5 mean (average):
The mean is at least (24 + 9)/5 = 33/5 = 6.6 since x is at least 9.
This is not convincing because the mean might be either millions or 6.6 (if x = 9) (if x is huge).

In ACDE, M/C = (x-4)°, m/D = (9x + 4)°, and m/E = (2x + 12)°.
Find m/D.
Thus, in ΔCDE the m/∠D = 130⁰, which can be calculated using angle sum property of triangle.
What is triangle?Triangle is derived from the Latin word triangulus, which means "three-cornered" or "having three angles," and is composed of the roots tri-, "three," and angulus, "angle or corner." Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The total of the triangle's three angles equals 180 degrees.
Given that: In ΔCDE
m/∠C = (x-4)°
m/∠D = (9x + 4)°
m/∠E = (2x + 12)°
Now, to find m/∠D
So, We know that sum of internal angles of a triangle is equal to 180⁰ .Here, we are given a ΔCDE and all its three internal angles.
Putting the sum of all three equal to 180⁰:
∠C + ∠D + ∠E = 180⁰(x-4)°+ (9x + 4)°+ (2x + 12)°
= 180⁰12x +12
= 180⁰x +1 = 15⁰
x = 14⁰
Thus, Putting value of x in m/∠D = (9x + 4)°.
m/∠D = (9 × 14 +4)⁰
m/∠D = 130⁰

you need to buy some chicken for dinner tonight. you found an ad showing that the store across town has it on sale for $3.19 a pound, which is cheaper than your usual neighborhood store, which sells it for $3.59 a pound. is it worth the extra drive? first, determine what information you need to answer this question, then click here to display that info (along with other info). how much chicken will you be buying? 3 pounds how much far are the two stores? my neighborhood store is 2.1 miles away, and takes about 7 minutes. the store across town is 8.5 miles away, and takes about 23 minutes. how kind of mileage does your car get? it averages about 19 miles per gallon in the city. how many gallons does your car hold? about 17 gallons how much is gas? about $3.83/gallon right now. going to the close store is cheaper going to the further store is cheaper the cheaper option saves you $
Yes, it is worth the extra drive, going to the further store is cheaper.
The cheaper option saves you $0.09.
Given:
Price or sale = $3.19 a pound
1.) Neighborhood store
Distance = 2.1 miles away
As, the car averages about 19 miles per gallon,
=2.1 miles / (19 miles/gallon)
= 0.1105 gallons of gas < 17 gallons
The gas is about $3.83/gallon, then the cost be
=0.1105 gallons x ($3.83/gallon)
= $0.42
The chicken is sold for $3.59 a pound, and you need 3 pounds, then you would pay:
= 3 pounds x ($3.59/pound)
= $10.77
So, the total is
= $0.42 (gas) + $10.77 (chiken)
= $11.19
2.) Store across town
Distance = 8.5 miles away
The car averages about 19 miles per gallon, then you would need:
=8.5 miles / (19 miles/gallon)
= 0.447 gallons of gas < 17 gallons
The gas is about $3.83/gallon, then the gas would cost:
=0.447 gallons x ($3.83/gallon)
= $1.71
The chicken is sold for $3.19 a pound, and you need 3 pounds, then you would pay:
= 3 pounds x ($3.19/pound)
= $9.57
The total cost
= $1.71 (gas) + $9.57
= $11.28
Thus, $11.19 < $11.28, then it is worth the extra drive.
Hence, cheaper option saves you= $11.28 - $11.19 = $0.09

What is meant by linear equation?A linear equation can be generated by equating a linear polynomial over some field with zero coefficients. The values that, when substituted for the unknowns, make the equality true are the solutions of such an equation. The phrase linear equation is frequently used to refer to this specific scenario, in which the variable is appropriately referred to as the unknown.
Each solution in the case of two variables can be regarded as the Cartesian coordinates of a point on the Euclidean plane. A linear equation's solutions form a line in the Euclidean plane, and every line can be seen as a set.
Sodium contains in a can of soup is 300mg
Sodium contains in a can of frozen dinners is 450mg
Let the number of cans of soup purchased be x
Then, the number of frozen dinners purchased=x+5
Total sodium purchased=6000mg

Side-Angle-Side is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent.SAS theorem of congruence: The SAS (side-angle-side) theorem of congruence states that if two sides and their included angle in one triangle are exactly equal to the corresponding two sides and their included angle in another triangle, then the two triangles are congruent.Using words: If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangles are congruent. Using labels: If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF.The proof by S A S congruence rule is given below.
Given from fig, JK || LM.
And JK = LM
Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.
So, angle KJL = angle MLN........equation 1
Also given L is the midpoint of JN so, JL = NL.....equation 2

What is a standard deviation?
The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a larger range.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle."
