Answer:
y-5=-2(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
m=-2
y-5=-2(x-(-3))
y-5=-2(x+3)
Let the second score = x
⇒ second score = x
<span>the first is 14 points more than the second
</span>⇒ first score = x + 14
<span>the sum of the first two is 6 more than twice the third
</span>⇒ third score = 1/2 (x + x + 14 - 6) = x + 4
<span>The sum of a student's three score is 246
</span>⇒ x + (x + 14) + (x + 4) = 246
<span>
Solve x:
</span>x + x + 14 + x + 4 = 246
3x + 18 = 246
3x = 228
x = 76
second score = x = 76
first score = x + 14 = 76 + 14 = 90
Answer: 90
The volume of the shelter is 1108.25 cu. ft.
<h3>What is a Cuboid?</h3>
A cuboid is a three-dimensional figure with 6 faces, all the faces are rectangular in shape.
The volume is the space occupied by it in a three-dimensional figure.
The volume of a cuboid whose length is l,
The width is w, and
Height is h.
V = length * Width * Height
V = lwh
The length of the shed is 16.25 ft.
The width of the shed is 11 ft.
The height of the shed is 6 1/5 ft
The height of the shed is 31/5 = 6.2ft.
The volume of the shed is given by
V = 16.25 * 11 * 6.2
V = 1108.25 cu.ft
Therefore, the shed has a volume of 1108.25 cu.ft.

This is parallelogram so
8=2x
X=4
Or
3x=12
So again we will find x=4
Answer:
mean=10.625=10.6
median=12
Step-by-step explanation:
Mean
The word mean, which is a homonym for multiple other words in the English language, is similarly ambiguous even in the area of mathematics. Depending on the context, whether mathematical or statistical, what is meant by the "mean" changes. In its simplest mathematical definition regarding data sets, the mean used is the arithmetic mean, also referred to as mathematical expectation, or average. In this form, the mean refers to an intermediate value between a discrete set of numbers, namely, the sum of all values in the data set, divided by the total number of values. The equation for calculating an arithmetic mean is virtually identical to that for calculating the statistical concepts of population and sample mean, with slight variations in the variables used
Median
The statistical concept of the median is a value that divides a data sample, population, or probability distribution into two halves. Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers. Note that when calculating the median of a finite list of numbers, the order of the data samples is important. Conventionally, the values are listed in ascending order, but there is no real reason that listing the values in descending order would provide different results. In the case where the total number of values in a data sample is odd, the median is simply the number in the middle of the list of all values. When the data sample contains an even number of values, the median is the mean of the two middle values. While this can be confusing, simply remember that even though the median sometimes involves the computation of a mean, when this case arises, it will involve only the two middle values, while a mean involves all the values in the data sample. In the odd cases where there are only two data samples or there is an even number of samples where all the values are the same, the mean and median will be the same
