2. The value, v, of the hat is less than $9.
what is the inequality
Answer:
v < 9
Step-by-step explanation:
Since the value of the hat is less than 9, we will use a less than sign.
In the inequality, the less than sign has to be in front of 9.
So, put this together:
v < 9
The inequality is v < 9
Find the measure of angle B
A power system will collapse if a ground fault occurs on any two of lines A, B, and C simultaneously. Assume that ground faults on lines A, B, and C are independent and have identical probability of 0.01. Hint: parts (a) and (b), use Bernoulli Trials; part (c), use Bayes Rule. a) What is the probability that the system will collapse
Answer:
0.000298 = 0.0298% probability that the system will collapse
Step-by-step explanation:
Number of possible ways the system can fail:
2 lines from a set of 3 fail, or all three fail.
Two from a set of 3:
Can be A and B, A and C, or B and C. Three possible outcomes then.
The probability of each is:
0.01*0.01*0.99
Two failling, each with 0.01 probability, and 1 working, with 0.99 probability.
All three:
Each with 0.01 probability.
a) What is the probability that the system will collapse
Both cases, so
[tex]p = 3*(0.01)^2*0.99 + (0.01)^3 = 0.000298[/tex]
0.000298 = 0.0298% probability that the system will collapse

A softball has a radius of 3 inches. What is the volume of the softball? Round your answer to the nearest whole number.
Answer:
38
Step-by-step explanation:
V = 4/3 (pie) r(cube)
V = 4/3 (3.14) 3(cube)
V = 4/3 (3.14) (9)
V = 4/3 (28.26)
V = 37.68
V = 38 (Rounded up)
Here are the noon temperatures (in degrees Celsius) in a particular Canadian city on Thanksgiving Day for the 10 years from 2002 through 2011: 0, 3, 6, 8, 2, 9, 7, 6, 4, 5. Describe the typical temperature and the amount of variation to a person who has never had a course in statistics. Give three ways of describing the representative temperature and two ways of describing its variation, explaining the differences and how you figured each. (You will learn more if you try to write your own answer first, before reading our answer at the back of the book.)
Answer:
a) Three ways of describing the representative or typical temperatures are the mean, median, and mode.
The mean = 5. This is the average temperature. It is calculated by adding up the varying temperatures each year and dividing by 10.
Median = 5.5. This is the middle value in the temperature table. There are two middle numbers (5 and 6) in the dataset. They are added and divided by two.
Mode = 6. This is the value that occurs more than other values in the dataset. The value 6 occurred twice more than other values.
b) The two ways of describing the variation of temperatures are the variance and the standard deviation.
Variance = 7. This is a measure of how spread out a data set is. It is calculated as the average squared deviation of each number from the mean of a dataset.
Standard Deviation = 2.65. The standard deviation measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
Step-by-step explanation:
a) Data and Calculations:
Noon Temperatures (in degrees Celsius) in a particular Canadian City on Thanksgiving Day:
Year Degree Difference Squared
Celsius Difference
2002 0 -5 25
2003 3 -2 4
2004 6 1 1
2005 8 3 9
2006 2 -3 9
2007 9 4 16
2008 7 2 4
2009 6 1 1
2010 4 -1 1
2011 5 0 0
Sum 50 70
Mean = 5 (50/10)
Variance = 7 (70/10)
Standard Deviation = 2.65 (Square root of variance)
Median = 0, 2, 3, 4, 5, 6, 6, 7, 8, 9 (the values are arranged numerically.)
= (5 + 6)/2 = 5.5
Mode = 6 (occurred twice more than other values)

What transformation is described by the
notation (x, y) —> x,-y)?
A : translation left 1 unit
B : translation down 1 unit
C : reflection across the x-axis
D : reflection across the y-axis
Answer:
C. reflection across the x-axis
Step-by-step explanation:
When a point is reflected across the x-axis, the x-coordinate stays the same while the y-coordinate turns into its opposite (positive to negative, negative to positive).
As we can see in the notation, the x-coordinate stayed the same while the y-coordinate went from positive to negative, which tells us that this notation is a reflection across the x-axis.

The perimeter of the parallelogram is of 44 units.
What is the perimeter of a figure?
The perimeter of a figure is given by the sum of all it's outside measures.
In this problem, since it is a parallelogram, we have that:
AD = BC
Hence:
3x - 1 = 2x + 2
x = 3
Hence:
AD = BC = 3x - 1 = 3(3) - 1 = 8
We also have that:
AB = DC
4y - 2 = 2y + 6
2y = 8
y = 4
Then:
AB = DC = 4y - 2 = 4(4) - 2 = 14
Thus, the perimeter is:
2 x (14 + 8) = 44 units.

F (x)=x+3x find f(2)
f(x)=3x-2 find f(-10)
help please
Answer:
f(x)=3x-2 is 4x i dont know bout the other one
Step-by-step explanation:
Answer:
1) f(2) = 8
2) f(-10) = -32
Step-by-step explanation:
Whenever you see a problem that asks something like what f(2) or f(-10) is, it is asking you to substitute whatever number is in the parentheses for every x in the given function.
1) So, to find f(2), substitute 2 for every x in the given function, f(x) = x + 3x and solve:
[tex]f(2) = (2)+3(2)\\f(2) = 2 + 6 \\f(2) = 8[/tex]
Thus, for this function, f(2) = 8.
2) Do the same with the second question. Substitute -10 for every x in the given function, f(x) = 3x - 2.
[tex]f(-10) = 3(-10) - 2 \\f(-10) = -30-2\\f(-10) = -32[/tex]
Thus, for this function, f(-10) = -32.

The cost of 7 chairs is equal to the cost of 2 tables. If the cost of 6 chairs and 5 tables is Rs.10,575, find the cost of 12 chairs.
Answer:
5,400
Step-by-step explanation:
7c = 2t; t = 7c/2
6c +5t = 10575
6c + 5(7c/2) = 10575
6c + 35c/2 = 10575
multiply all through by 2
12c + 35c = 21,150
47c = 21,150
c = 21150/47 = 450
12 chairs = 450 × 12 = 5,400
