Answer:
8/9 + 1/6 = 1 1/18
Step-by-step explanation:
1. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
8/9*2/2 + 1/6*3/3 = ?
2. Complete the multiplication and the equation becomes 16/18 + 3/18.
3. 16/18+3/18 = 19/18 = 1 1/18

The classic 60° triangle has a hypotenuse of length 2, an opposite side of length √3 and an adjacent side of length 1....find the value of Cos(60°)
Answer:
The trigonometric values for cos are C = A/H, which means that to find cos(60), you need to divide the adjacent side by the hypotenuse, which in this case gives you 1/2, so that is the value of cos(60).

If you subtract 69 from 769 giving you 700 and divide by 2. You will be get 350 hamburgers and 419 cheeseburgers.
Evaluate and simplify the expression when a = 3 and b = 2. 3b-2(1 - b) a - 2 II [ ? ] Enter Copyright © 2003.2010
Correct question:
Evaluate and simplify the expression when a = 3 and b = 2,
given expression = 3b-2(1 - b)a - 2
Answer:
3b-2(1 - b)a - 2 at the given values is 10.
Step-by-step explanation:
Given;
3b-2(1 - b)a - 2
The expression is simplified as;
3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2
= 3b - 2a + 2ab - 2
When a = 3 and b = 2; then, substitute these values in the simplified expression above;
3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2
= 6 - 6 + 12 - 2
= 10
Therefore, 3b-2(1 - b)a - 2 at the given values is 10.

A circle has a diameter of 10 meters. What is the length of the arc subtended by a central angle of 4 radians.
A. 40 meters
B. 20 meters
C. 4 meters
D. 10 meters
Answer:
b
Step-by-step explanation:
The length of the arc subtended by a central angle of 4 radians = 20 m
Diameter of the circle = 10 m
Radius of the circle = 5 m
Central angle in radians = 4 radians
The length of arc for the circle can be determined by the formula as formulated in equation (1)
[tex]\rm L = Length\; of \; Arc \\\theta = Central \; Angle \; in \; radians \\r = Radius\; of\; the\; circle\\L = \theta \times r.......(1)[/tex]
From equation (1) we can write that
[tex]\rm L = 5 \times 4 = 20 \; m[/tex]
The length of the arc subtended by a central angle of 4 radians = 20 m

A study of the career paths of hotel general managers sent questionnaires to an SRS of 210 hotels belonging to major U.S. hotel chains. There were 108 responses. The average time these 108 general managers had spent with their current company was 8.8 years. (Take it as known that the standard deviation of time with the company for all general managers is 3.5 years.)
Required:
a. Find the margin of error for an 85% confidence interval to estimate the mean time a general manager had spent with their current company.
b. Find the margin of error for a 99% confidence interval to estimate the mean time a general manager had spent with their current company.
Answer:
a
[tex]E = 0.4850 [/tex]
b
[tex]E = 0.8689[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 108
The sample mean is [tex]\= x = 8.8 \ years[/tex]
The standard deviation is [tex]\sigma = 3.5[/tex]
From the question we are told the confidence level is 85% , hence the level of significance is
[tex]\alpha = (100 - 85 ) \%[/tex]
=> [tex]\alpha = 0.15[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.44 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.44 * \frac{ 3.5 }{\sqrt{108} }[/tex]
=> [tex]E = 0.4850 [/tex]
From the question we are told the confidence level is 99% , hence the level of significance is
[tex]\alpha = (100 - 99 ) \%[/tex]
=> [tex]\alpha = 0.01[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.58 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.58 * \frac{ 3.5 }{\sqrt{108} }[/tex]
=> [tex]E = 0.8689[/tex]

You are given the following set of data. Its mean is 293.
225, 259, 306, 325, 350
If 25 is subtracted from each value, what will be the new mean?
A. 293
B. 268
C. 234
D. 200
Answer:
B. 268
Step-by-step explanation:
The new mean for the given data set can be obtained as 268.
How to calculate the average or mean?In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.
The given data is 225, 259, 306, 325, 350.
And, its mean is given as 293.
Here, the number of elements is 5.
If 25 is subtracted from each value, new mean can be evaluated as below,
New mean = (Old mean × 5 - 25 × 5)/5
⇒ (293 × 5 - 25 × 5)/5
⇒ 293 - 25 = 268
Hence, the new mean can be obtained as 268.

prove a stronger version of proposition 2.3.7 suppose xn ia a sequence such that every subsequence xni has a subsequence xnmi that converges to x
Answer and Step-by-step explanation:
Solution:
Given:
A, B and C are sets.
We have to prove that:
(A − B) ∩ (C − B) = (A ∩ C) − B.
Use an element x,
Let x Є (A – B), by the definition of difference:
X Є A and x ∉ B.
And
X Є A ∩ C and x ∉ B
X Є (A ∩ C) – B
Now let x Є C – B
By the definition of difference:
X Є C and x ∉ B
By definition of intersection: x Є C and x Є( A ∩ C)
By definition of difference, using that x Є(A ∩ C) And x ∉ B:
X Є ( A ∩ C) – B
We know that: x Є (A – B) ∩ ( C – B)
Is equivalent to x Є A – B and x Є C – B
So, ( x Є A and x ∉ B)
And (x Є C and x ∉ B)
From this we know that x Є (A ∩ C) – B.
