Answers
Answer: It's A
Step-by-step explanation:
Solve. x/4 + ½ = 1/8
x = ____ (Simplify your answer.)
Answers
Answer:
\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)
\( \frac{x}{4} = - \frac{3}{8} \)
\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.
Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.
x/4 + 1/2 = 1/8
Take the 1/2 term on the other side,
x/4=1/8 - 1/2
Taking the LCM on the Right side,
x/4 = (1-4) / 8
x/4 = -3/8
Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,
x = ( -3/8) * 4
x = -3/2
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

The greatest integer funtion, shown below, is defined to be the greatest ______ less than or equal to x.
f(x)={{x}}
Answers
Answer:
Integer
Step-by-step explanation:
The greatest integer function (as known as the floor function), is defined as to be the greatest integer less than or equal to x.
It is the function:
\(f(x)=\floor[x]\)
For instance, if x is 2, then f(x) is 2. If x is 2.7, then f(x) is still 2. 2 is the greatest integer less than or equal to 2.

Use a number line to create a sign chart of each polynomial function
F(x)=-(x+5)(x-2)(2x-4)(x-4)^2
Answers
To create a sign chart for the polynomial function F(x) = -(x+5)(x-2)(2x-4)(x-4)², we will examine the intervals defined by the critical points and the zeros of the function.
Analyzing the Sign Chart1. Determine the critical points -
- The critical points occur where the factors of the polynomial change sign.
- The critical points are x = -5, x = 2, x = 4, and x = 4 (repeated).
2. Select test points within each interval -
- To evaluate the sign of the polynomial at each interval, we choose test points.
- Common choices for test points include values less than the smallest critical point, between critical points, and greater than the largest critical point.
- Let's choose test points - x = -6, x = 0, x = 3, and x = 5.
3. Evaluate the sign of the polynomial at each test point
- Plug in the test points into the polynomial and determine the sign of the expression.
The sign chart for F(x) = -(x+5)(x-2)(2x-4)(x-4)² would look like this
Intervals Test Point Sign
-∞ to -5 -6 -
-5 to 2 0 +
2 to 4 3 -
4 to ∞ 5 +
Note - The signs in the "Sign" column indicate whether the polynomial is positive (+) or negative (-) in each interval. See the attached sign chart.

An optical inspection system is used to distinguish among different part types. The probability of correct classification of any part is 0. 98. Suppose that three parts are inspected and that the classifications are independent. Let the random variable x denote the number of parts that are correctly classified. Determine the probability mass function and cumulative mass function of x.
Answers
The probability mass function (PMF) for x is {0.0004, 0.0588, 0.3432, 0.941192}, and the cumulative mass function (CMF) for x is {0.0004, 0.0592, 0.4024, 1.0}.
The probability mass function (PMF) and cumulative mass function (CMF) for the random variable x, which denotes the number of parts correctly classified in an optical inspection system, can be determined.
Since the classifications of the parts are independent, we can use the binomial probability distribution to model this scenario. The PMF gives the probability of obtaining a specific value of x, and the CMF gives the probability of obtaining a value less than or equal to x.
The PMF of x is given by the binomial probability formula:
P(x) = (n C x) * p^x * (1 - p)^(n - x)
where n is the number of trials (number of parts inspected), x is the number of successes (number of parts correctly classified), and p is the probability of success (probability of correct classification of any part).
In this case, n = 3 (three parts inspected) and p = 0.98 (probability of correct classification).
Let's calculate the PMF for x:
P(x = 0) = (3 C 0) * (0.98^0) * (1 - 0.98)^(3 - 0) = 0.0004
P(x = 1) = (3 C 1) * (0.98^1) * (1 - 0.98)^(3 - 1) = 0.0588
P(x = 2) = (3 C 2) * (0.98^2) * (1 - 0.98)^(3 - 2) = 0.3432
P(x = 3) = (3 C 3) * (0.98^3) * (1 - 0.98)^(3 - 3) = 0.941192
The PMF for x is:
P(x = 0) = 0.0004
P(x = 1) = 0.0588
P(x = 2) = 0.3432
P(x = 3) = 0.941192
To calculate the CMF, we sum up the probabilities up to x:
F(x) = P(X ≤ x) = P(x = 0) + P(x = 1) + ... + P(x = x)
Using the calculated probabilities, the CMF for x is:
F(x = 0) = 0.0004
F(x = 1) = 0.0592
F(x = 2) = 0.4024
F(x = 3) = 1.0
Therefore, the probability mass function (PMF) for x is {0.0004, 0.0588, 0.3432, 0.941192}, and the cumulative mass function (CMF) for x is {0.0004, 0.0592, 0.4024, 1.0}.

Step-by-step explanation:
Angles in a triangle add up to 180 degrees:
34 + 77 + x = 180
x = 69
Angles on a straight line add up to 180:
77 + v = 180
v = 103
Answer:
x = 69°V = 103°Step-by-step explanation:
the sum of the interior angles in a triangles is 180°, take away from 180 the know angles (34° and 77°) and you will have your answer
180 - 34 - 77 = 69°
Now we find angle V
The angle V and the angle of 77 ° are on a straight line, so the sum is 180°, from 180° you subtract 77 ° and you have the value of V
180 - 77 = 103 °

You are managing one of the Tandoor-India's restaurant. All the table are walk-in (no reservation can be made in advance). Customers that arrive and request a table are divided as follows: 50% require a table of size two, 40% require a table of size four, and 10% request a table of size six. The average waiting times for each type of table is given as: The number of parties waiting for a table for two is on average 2 . Hint: This question is on the Little's law. a) What is the arrival rate of parties requesting of size two per hour? 12 parties per hour. b) What is the total arrival rate of parties requesting tables (of any size) per hour? 24 parties/hr. c) What is the average number of parties requesting table of size four per hour? 9.6parties/hr. d) What is the average number of parties waiting for a table for four?
Answers
a) The arrival rate of parties requesting a table of size two per hour is 50% of the total arrival rate. Therefore, it is 0.5 * 24 = 12 parties per hour.
b) The total arrival rate of parties requesting tables of any size per hour is 24 parties per hour.
c) The average number of parties requesting a table of size four per hour is 40% of the total arrival rate. Therefore, it is 0.4 * 24 = 9.6 parties per hour.
d) The average number of parties waiting for a table of size four is given as 2 parties.
a) The arrival rate of parties requesting a table of size two per hour is calculated by taking the percentage of parties requesting a table of size two out of the total arrival rate. In this case, 50% of the parties require a table of size two. So, the arrival rate for parties requesting a table of size two is 0.5 * 24 = 12 parties per hour.
b) The total arrival rate of parties requesting tables of any size per hour is simply the sum of the arrival rates for each table size. In this case, we have an arrival rate of 12 parties per hour for tables of size two, 40% of the parties require a table of size four (which corresponds to an arrival rate of 0.4 * 24 = 9.6 parties per hour), and 10% of the parties request a table of size six (which corresponds to an arrival rate of 0.1 * 24 = 2.4 parties per hour). Adding these arrival rates together gives a total arrival rate of 12 + 9.6 + 2.4 = 24 parties per hour.
c) The average number of parties requesting a table of size four per hour is calculated by taking the percentage of parties requesting a table of size four out of the total arrival rate. In this case, 40% of the parties require a table of size four. So, the average number of parties requesting a table of size four per hour is 0.4 * 24 = 9.6 parties per hour.
d) The average number of parties waiting for a table of size four is given as 2 parties. This means, on average, there are 2 parties waiting for a table of size four at any given time.

Two cars leave an intersection at the same time. One drives east while the other travels south at 15 miles per hour faster than the other. After 3 hours, the cars are 225 miles apart. How fast is the southbound car driving?
Answers
Answer:
60 mph
Step-by-step explanation:
Let 'S' be the velocity of the southbound car and 'E' be the velocity of the eastbound car. The distances traveled by each car are:
\(D_E=3E\\D_S=3S=3(E+15)\\D_S=3E+45\)
The distance between both cars is given by:
\(D^2=D_S^2+D_E^2\\225^2=(3E+45)^2+(3E)^2\\50,625=9E^2+270E+9E^2+2,025\\18E^2+270E-48,600=0\\\)
Solving the quadratic equation for the velocity of the eastbound car:
\(18E^2+270E-48,600=0\\E^2+15E-2,700\\E=\frac{-15\pm\sqrt{15^2-4*1*(-2,700)}}{2}\\E=45.0\ mph\)
The velocity of the southbound car is:
\(S=E+15=45+15\\S=60\ mph\)
The southbound car is driving at 60 mph.
