The shape of the data that we have here is skewed to the right
How is a data skewed to the right?A dataset is considered to be right-skewed (sometimes known as excessively positive) when the greater portion of its data points are concentrated on the lower end, forming an asymmetrical distribution that has a long tail to the right.
As such, the mean (average) within these distributions generally surpasses the median in value, with the latter also exceeding the mode.

What is the probability of picking a 9 and then picking a number less than 8?
Simplify your answer and write it as a fraction or whole number.
The probability of picking a 7 and then picking a number greater than 7 is 1/3.
Now, given that we have already picked three cards. So, 7, 8, and 9.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
The number of possible outcomes is 3.
Probability of picking 7 = 1/3
Now, as card seven is already picked up cards 8 and 9 are the only card left.
therefore, the sample size(possible outcomes) was reduced to 2 only.
Also, cards 8 and 9 both are greater than 7, thus the desired outcome is also 2.
Further the probability of the number greater than 7 occurring,
Probability (n>7) = 2/2 =1
Probability picking a number greater than 7
The probability of picking a 7 and then picking a number greater than 7
= Probability of card 7 occuring x probability of card 8 and 9 occurring

Answer:
the value of the expression 14 1/3 - 6 5/8 is 185/24.
Step-by-step explanation:
To solve this problem, you can convert both mixed numbers to improper fractions, then subtract the fractions and simplify the result. Here are the steps:
1. Convert 14 1/3 to an improper fraction:
14 1/3 = (14 x 3 + 1) / 3 = 43 / 3
2. Convert 6 5/8 to an improper fraction:
6 5/8 = (6 x 8 + 5) / 8 = 53 / 8
3. Subtract the fractions:

We have,
The statement that is true about the graph of y = 0.25(2^x).
The coordinates of the y-intercept are (0, 1/4).
We can see this by setting x = 0 in the equation,
which gives,
y = 0.25 x 2^0 = 0.25 x 1 = 1/4.
Therefore, the y-intercept is at (0, 1/4).
The other statements are false:
The graph increases from left to right, since 2^x increases as x increases.
The coordinates of the y-intercept are not (0, 14), but rather (0, 1/4).
There is no vertical asymptote in the graph.
The x-intercept occurs where y = 0, which gives 0.25 * 2^x = 0. Solving for x gives x = -2.
Therefore, the coordinates of the x-intercept are (-2, 0), not (2, 0).

b/sin31 = 13/sin60
b = 13*sin60)/sin31
b = 13*0.5150 /0.8660
b = 7.7cm
|DC| = 8cm
To find /ED/ using the same formula
a/sinA = b/sinB = c/sinC
Note that <DCE = 180- (36+15) = 129
Tis implies that
c/sin129 = 8/sin15
c= (8*0.7771)/0.2588
c = 24 cm
To find |EC| using the same formula
a/sinA = b/sinB = c/sinC
d/sin36 = 8/sin15
d*sin15 = 8*sin36
d= (8*sin36)/sin15
d = (8*0.5878)/ 0.2588
d = 18cm
|EC|= 18 cm
Finally, To find |EA| using the cosine formula
Note that < ECA = 180-78 = 102
c² = a² +e²-2*aecos102
c²= 18²+8²-2*18*8*-0.2079
c² = 324 +64 +60
c² = 448

HELPPP THIS IS FOR GEOMETRY
Answer:
Parallelogram
Step-by-step explanation:
You want the name of the figure defined by vertices I(2, -3), J(0, 0), K(4, 6) and L(6, 3).
ParallelogramA quick check will tell if the figure is a parallelogram. The diagonals will have the same midpoint.
(I +K)/2 = (J +L)/2
I +K = J +L . . . . . . . . multiply by 2 to make the math easier
(2, -3) +(4, 6) = (0, 0) +(6, 3) . . . . . substitute the given points
(6, 3) = (6, 3) . . . . . . . . . . . . . . the sums are equal
The figure is a parallelogram.
DiagonalsA parallelogram can be a rectangle, square, or rhombus. We can determine if it is a square or rectangle by looking at the lengths of the diagonals. First, we need to find the differences of their endpoints.
K -I = (4, 6) -(2, -3) = (4 -2, 6 +3) = (2, 9)
L -J = (6, 3) -(0, 0) = (6, 3)
The lengths will be the root of the sum of the squares. We can compare the lengths by comparing the sum of the squares (without taking the root):
2² +9² = 4 +81 = 85
6² +3² = 36 +9 = 45
The diagonals are different lengths, so the figure is not a rectangle.
Right anglesWe can make another check to see if the figure is a rhombus. In a rhombus, the diagonals are perpendicular. The "dot product" of the differences we just found will be zero in that case.
(2, 9)•(6, 3) = (2)(6) +(9)(3) = 12 +27 = 39 ≠ 0
The diagonals are not perpendicular, so the parallelogram is not a rhombus.
The most specific name of the figure is Parallelogram.

Additional comment
A lot is answered by graphing the points. The slopes and lengths of the lines can be found by counting grid squares between points horizontally and vertically. It is easy to see the diagonals cross at their midpoints, and that they are different lengths.
You can figure segment lengths and slopes for showing opposite sides are the same lengths and parallel, but we find the diagonal midpoint computation to be much easier for showing the figure is a parallelogram.

Find the area of the region inside the inner loop of the limaçon r=3−6cosθ.The area of the region is??
The area of the region inside the inner loop is 4.5π
How to calculate the areaUsing the formula A = 1/2 ∫[a,b] r^2(θ) dθ. In the case of the limaçon's inner loop, a has been set as 0, b is equal to π, and r equals 3 - 6 cosθ. Together, these values give us the following equation expression for the area:
A = 1/2 ∫[0,π] (3 - 6 cosθ)^2 dθ
= 1/2 ∫[0,π] (9 - 36 cosθ + 36 cos^2θ) dθ
= 1/2 [9θ - 36 sinθ + 12 sin(2θ)]|[0,π]
= 1/2 [9π]
= 45π
Therefore, the area of the inner loop in this instance is calculated as 4.5π.

The number of miles m (in billions) traveled by vehicles in City A can be modeled by
m = 2.86t + 112 where t is the number of years since 1994. Use a graphing calculator to
approximate the year in which the number of vehicle miles of travel in City A was 140 billion.
Based on the linear model, the number of vehicle miles of travel in City A was 140 billion in the
year
The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,
t = 9.79 years
Given that;
The number of miles m (in billions) traveled by vehicles in City A can be modeled by,
m = 2.86t + 112
where t is the number of years since 1994.
Hence, We can formulate;
The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,
m = 2.86t + 112
140 = 2.86t + 112
140 - 112 = 2.86t
28 = 2.86t
t = 28/2.86
t = 9.79 years
Thus, The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,
t = 9.79 years
