What is the surface area of the right cone below?
The surface area of the right cone in terms of pi is 176π units².
How to calculate the surface area of a cone?A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The surface area of a cone is expressed as;
Surface area = πrl + πr²
Where r is the radius of the base, l is the slant height of the cone and π is constant pi.
From the diagram:
Radius r = 8 units
Slant height h = 14 units
Surface area =?
Plug the given values into the above formula and solve for surface area:
Surface area = πrl + πr²
Surface area = ( π × 8 × 14 ) + ( π × 8² )
Surface area = ( π × 112 ) + ( π × 64 )
Surface area = 112π + 64π
Surface area = 176π units²
Therefore, the surface area is 176π units².
Option A)176π units² is the correct answer.

Solve the system of equations -x-y=-4−x−y=−4 and -2x+4y=4−2x+4y=4 by combining the equations.
9514 1404 393
Answer:
(x, y) = (2, 2)
Step-by-step explanation:
We can put the second equation into standard form by dividing by -2.
x -2y = -2
Adding this to the first equation eliminates x
(x -2y) +(-x -y) = (-2) +(-4)
-3y = -6
y = 2 . . . . . divide by -3
-x -(2) = -4 . . . . substitute for x in the first equation
2 = x . . . . . . . . add 4+x
The solution is (x, y) = (2, 2).
what is the probability that a randomly selected upper level statistics class has at least 10 students g
Answer:
0.55
Step-by-step explanation:
Given
See attachment for table
Required
[tex]P(x \ge 10)[/tex]
To do this, we consider rows where x is either 10 or greater than 10
i.e. 10, 11 and 12
So:
[tex]P(x \ge 10) = P(10) + P(11) + P(12)[/tex]
Using values from the table, we have:
[tex]P(x \ge 10) = 0.20 + 0.25 + 0.10[/tex]
[tex]P(x \ge 10) = 0.55[/tex]
The cost of 6 pens is $3.60. What would 2 dozen cost?
$14.40. And then you have the tax. :D
Have A Great Day.
The cost of 2 dozen pens will be "$14.4".
Given:
Cost of 6 pens,
$3.60As we know,
1 dozen = 12then,
12 dozen = [tex]12\times 2[/tex]= [tex]24[/tex]
Now,
→ The cost of 1 pen will be:
= [tex]\frac{3.60}{6}[/tex]
= [tex]0.6[/tex] ($)
hence,
→ The cost of 24 pens (2 dozen) will be:

Examples of graphs of a single variable include pie charts, bar graphs, and time-series graphs. a. True b. False
Answer:
False.
Step-by-step explanation:
Time-series graph is a graph that relates something to the change of time, then the time is the single variable in this case.
Bar graphs relate a given quantity to a given variable, an example of this can be the population of a given city (represented by the height of each bar) for each different year (which is the single variable in this case)
Pie-chart is a circular graph with defined sections that represent a given proportion. This kind of graph is used to represent percentages, like in the case of a pie chart that describes the number of men and women in a city. (one section of the circle represents the percentage of women and the other section of the circle represents the percentage of men). In this type of graph, there are no variables, so this is not a single variable graph.
Then the statement:
"Examples of graphs of a single variable include pie charts, bar graphs, and time-series graphs."
Is false.

find x and y. give answer in insimplified radical form, not decimal.
Finding x,
We will use Pythagoras theorem to determine the value of x:
[tex]9^{2} = {8}^{2} + {x}^{2} \\ 81 = 64 + {x}^{2} \\ 81 - 64 = {x}^{2} \\ {x}^{2} = 17 \\ x = \sqrt{17} [/tex]
Finding y,
We have to determine the angle, at the bottom left of the bigger triangle.
Using sine rule,
[tex] \frac{9}{sin(90)} = \frac{8}{sin(z)} \\ sin(z) = 0.8889 \\ z = {sin}^{ - 1} (0.8889) \\ z = 62.73[/tex]
To find the angle on the smaller triangle,
[tex]a = 90 - 62.73 \\ a = 27.27[/tex]
Finding the missing length of y,
[tex] \frac{ \sqrt{17} }{sin(62.73)} = \frac{m}{sin(27.27)} \\ m = 2[/tex]
So y = 2 + 8, y = 10

What are rotation and translation?Rotation involves moving an object about a fixed point. Each point on the object describes a circular path with the center, the center of rotation.
Translation involves moving an object such that only one of the three cartesian coordinates changes during the transformation.
here, we have,
Rotation
Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.
Vertical Translation
After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.
Horizontal Translation
The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.
Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

A doctor has 53 ccs of a 40% solution of a pain killer. How much sterilized water should be added to get a 27% solution?
Answer:
35.775
Step-by-step explanation:
So, 53 is the amount of ccs that makes a 40% solution.
How can we find the ccs of 27% solution?
Well, we should first find teh amount of ccs per 1%.
To do this, divide 53 by 40:
53/40
=
1.325
Now multiply this by 27 to get the amount of ccs for 27%:
27*1.325
=
35.775

The M&Ms milk chocolate color distribution is the following: 25% blue, 35% orange, 23% red, and 17% brown. In a bag, I found 164 blue M&Ms, 239 orange ones, 170 red ones and 136 brown ones. I am wondering whether my bag of M&Ms is representative of the manufacturer’s claim. Calculate the absolute value of the test statistic.
Answer:
1646.857
Step-by-step explanation:
The test statistic is obtained using the relation :
χ² = Σ (observed - Expected)² / expected
The observed values :
Blue = 164 ; Orange = 239 ; Red = 170 ; Brown = 136
Expected values:
Blue = 0.25 * 164 = 41 ;
Orange = 0.35 * 239 = 83.65
Red = 0.23 * 170 = 39.1
Brown = 0.17 * 136 = 23.12
Blue = (164-41)^2 / 41 = 369
Orange = (239 - 83.65)^2 / 83.65 = 288.507
Red = (170 - 39.1)^2 / 39.1 = 438.230
Brown = (136 - 23.12)^2 / 23.12 = 551.12
χ² = (369 + 288.507 + 438.230 + 551.12)
χ² = 1646.857
Find M Please help!!!! Last question worth 10 points!
Answer:
<A = 75degrees
Step-by-step explanation:
From the triangle given;
arcDA + arc AD + arcBD = 360 degrees
131 + 79 + arcBD = 360
210 + arcBD = 360
arcBD = 360 -210
arcBD = 150 degrees
Since the angle at the vertex <A is half that at the arc BD, hence;
<A = 1/2 arcBD
<A = 1/2 * 150
<A = 75degrees
Hence the measure of angle A s 75degrees

Length of arc AB on circle is 30.72 m.
What is circular arc?A circular arc is an arc between two different points. If the two points are not diametrically opposed, one of these arcs, the minor arc, forms an angle of less than π radians (180 degrees) with the center of the circle. The other circular arc, the main arc, makes an angle greater than π radians. An arc is defined as a portion or segment of the circumference. A straight line connecting the two ends of an arc is called a chord. If the arc length is exactly half the circle, it is called a half arc.
Given,
Circle with center O
Radius of circle OA = OB = 8m
Angle made by minor arc AB on center of circle α = 140°
then angle made by main arc AB = 360° - 140° = 220°
π = 180°
1° = π/180°
220° = 220°π/180°
220° = 11π/9
220° = 3.84 Rad
Length of arc on circle
= Radius of circle × angle made by the arc on center of circle in radians
= 8 × 3.84
= 30.72 m
Hence, 30.72 m is length of the arc AB.
