Answer:
The mean absolute deviation is 2. Hope this helps
Step-by-step explanation:
7+2+8+9+9+5+6+8+1=5.5
7-5.5=1.5
5.5-2=3.5
8-5.5=2.5
9-5.5=3.5
9-5.5=3.5
5.5-5=0.5
6-5.5=1.5

Evaluate -2x^3-3x^2+4 for x=-2
Answer: 8
Step-by-step explanation:
1. Rewrite the equation:
-2x^3 - 3x^2 + 4 x = -2
2. Plug in the value of x, -2
-2(-2)^3 - 3(-2)^2 + 4
3. Use order of operations (PEMDAS):
-2(-8) - 3(4) + 4
= 16 - 12 + 4
= 8

what is the equation that has an x intercept of 4 and yintercept of 2. Show your work please
Answer:
y = -1/2x + 2
Step-by-step explanation:
If you are talking about a linear equation then b=2
The slope is y2 - y1 / x2 - x1 so 2-0/0-4 = 2/-4 = -1/2
So put it all together in y = mx + b so y = -1/2x + 2

For each of the following studies, say whether you would use a t test for dependent means or a t test for independent means.
a. A researcher randomly assigns a group of 25 unemployed workers to receive a new job skills program and 24 other workers to receive the stan- dard job skills program, and then measures how well they all do on a job skills test.
b. A researcher measures self-esteem in 21 students before and after taking a difficult exam.
c. A researcher tests reaction time of each member of a group of 14 individuals twice, once while in a very hot room and once while in a normal- temperature room.
Answer:
1. T test for independent means
2. T test for dependent means
3. T test for dependent means
Step-by-step explanation:
In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.
- The groups in the experiment are unrelated
- The tests in the research are unrelated
- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.
In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.
What are the solutions of the quadratic equation 4x2 - 8x – 12 = 0?
Answer:
see bottom
Step-by-step explanation:
divide through by 4
x2 - 2x - 3 = 0
x2 - 3x + x - 3 = 0
(x2 - 3x) + (x - 3) = 0
x(x - 3) + 1(x - 3) = 0
(x + 1) (x - 3) = 0
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
AUTHORITY ? description In your own words .this phrase has probably done more damage to investors than just about any other in all of market history.
Answer:
Authority is the accepted power of a person or an organization to lead another person or group. In a political sense, authority also stands for the power and dominion over an area or country held by the government. Authority legitimized by law or government is called 'competent authority'. A person who is generally respected by knowledge or status in a certain area is 'authoritative' in that area.
Authority regulates the relationships between people in society. If authority is absent, anarchy reigns. The difference between authority and power is that authority is legitimate. It has the right to exercise this power by, for example, imposing sanctions.

6. A cylindrical oatmeal canister has a diameter of 4 inches and a hight of 10 inches. The manufac-
turing company wants to package the oatmeal in square containers to cut back on wasted storage
space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have,
to the nearest % inch, to hold the same volume of oatmeal? Use 3.14 for the value of T.
a. 7 3/4 inches
b. 8 inches
c. 8 1/4 inches
d. 8 1/2 inches
e. 8 3/4 inches
The minimum height the square containers should have is 8 inches.
What should be the minimum height the square containers ?The first step is to determine the volume of the cylindrical oatmeal canister.
Volume = 1/3πr²h
Where:
π = 3.14
r = radius 4/2 = 2
3.14 x 2² x 10 = 125.6
Now, determine the minimum height of the square box.
Height = volume of the cannister / (area of the base)
125.6 / (4 x 4) = 7.85 = 8 inches

Answer:
x=60
Step-by-step explanation:
(1/6)(x+6)=11
Multiply both sides by six:
(6)(1/6)(x+6)=11(6)
x+6=66
Take six from both sides:
x+6-6=66-6
x=60

: Find the equation of the tangent line to the curve f(x)= e^xat x_0= 2, and show this line on the graph.
The tangent line to f(x) = e ˣ at the point x = 2 has slope equal to f ' (2):
f(x) = e ˣ → f '(x) = e ˣ → f ' (2) = e ²
At x = 2, the function takes on a value of f (2) = e ². Use the point-slope formula to get the equation of the tangent line:
y - e ² = e ² (x - 2)
Solve for y :
y = e ² x - e ²

The graph represents the gallons of water (y) per minute (x) dispensed by a shower head. Which statements are correct?
The relationship has been analysed using the property of straight line.The correct options are (C), (D) and (E) respectively.
How to represent a straight line on a graph?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
The given options are examined one by one as follows,
(a) The point (0, 0) on the graph represents the zero number of gallons dispensed at the beginning.
(b) The point (5, 1) does not lie on the graph.
(c) The point (1, 5) represents 5 gallons dispensed during 1 minute which is equivalent to the unit rate.
(d) The point (1.5, 7.5) lies on the graph which represents 7.5 gallons dispensed in 1.5 minutes.
(e) The point (0, 0) shows no gallons dispensed at t = 0.
Hence, the correct information inferred from the graph are the point (1, 5) represents the unit rate, 7.5 gallons for 1.5 minutes and the point (0, 0) represents zero minutes for zero gallons.
