Describe the trend/correlation
shown in the scatter plot below
Answer:
Negative correlation.
Step-by-step explanation:
Negative correlation means that as x increases, y decreases
Positive correlation means that as x increases, y also increases.
No correlation means that neither of the two above cases happens.
In the graph, we can see that on the right (when x is negative) the general y values are larger.
As x increases, the y-values decrease.
(Particularly, we could adjust these data with a linear equation with a negative slope)
Then this is a negative correlation.

According to the stem-and-leaf plot above, how many drivers travel below 80 miles hour per hour? A. 2 B. 6 C. 14 D. 5
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot
Required
Drivers that travel below 80 mph
A stem and leaf plot has the following syntax: Stem | Leaves
Take for instance:
7 | 2 3 4 7
The above represents 72, 73, 74 and 77
Using the above illustration, the attached leaf plot can be interpreted as:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
80 81... and so on
The drivers that drive below 80 mph are:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
And the frequency is: 12
Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)
Find the lateral area of the cone to the nearest whole
number.
Answer:
lateral area = pi x radius x slant height
slant height = 40^2 + 30^2 = 1600 + 900= [tex]\sqrt{2500}[/tex] = 50
3.14 x 30 x 50 = 4710m^3

the following image is a trapazoid.if XW is congruent YZ and measaure of m = 72 degrees. calculate the measure of X
Answer:
opposite angle of trapezoid is supplementary
<Z+<X=180°
<X=180°-72°
<x=108°
is your answer
The required value of the measure of the angle x is 108°. Option A is correct.
The following image is a trapezoid. if XW is congruent to YZ and measure of m = 72 degrees. calculate the measure of X is to be determined.
The angle can be defined as the one line inclined over another line.
What is a trapezoid shape?A trapezoid is defined as a quadrilateral with one couple of opposite sides parallel. the sum of the opposite angles is 180. Only one pair of opposite sides should be parallel not all the sides if all sides are parallel then the shape became a rectangle or rhombus.
Since the sum of the opposite angles in trapezoids is 180°
so,
x + 72° = 180°
x = 180° - 72°
x = 108°
Thus, the required value of the measure of the angle x is 108°.

7
3 = 7 - 4
-1 = 3 - 4
-5 = -1 - 4
so the 5th: -5 - 4 = -9
the 6th: -9 - 4 = -13

Area of a circle is
[tex]\pi {r}^{2} [/tex]
each square has an area of 1
There are four semi-circles, which make two complete circles.
the area of the 5 squares plus the area of the two circles equals the total area.

Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²hello please help prize is brainliest
