it's kinda confusing b/c of the minus signs.. huh... but -5 is less than -2 sooo
start with
-2 1/2 - (-5 3/4 )
=5 3/4 - 2 1/2
=5 3/4 - 2 2/4
=23/4 - 10/4

Jess is having a private party at the bowling alley. The party costs $99 plus %3 per person who attends.
Answer:
Total cost= 99 + 2.97x
Step-by-step explanation:
Giving the following information:
Fixed cost= $99
Variable cost= 3% per person
First, we need to calculate the 3% of 99:
Unitary variable cost= 99*0.03= $2.97
Now, we establish the total cost structure:
Total cost= 99 + 2.97x
x= number of people in attendance
Finally, suppose 200 people attend the party:
Total cost= 99 + 2.97*200
Total cost= $693

The labor charges for mechanics is $54 an hour. The
standard deviation is $4 an hour. Find the minimum percentage of
data values that lie within the range of $48 to $60 an hour for the
mechanic's labo
The minimum percentage of data values that lie within the range of $48 to $60 an hour for the mechanic's labor is 86.64%.
To find the minimum percentage of data values that lie within the range of $48 to $60 an hour for the mechanic's labor.
We need to calculate the z-scores for both values and use a z-table to find area under the normal curve between those two scores.
First, we calculate the z-score for $48 an hour:
z = (48 - 54) / 4 = -1.5
Next, we calculate the z-score for $60 an hour:
z = (60 - 54) / 4 = 1.5
Using a standard normal distribution table, we can find that the area under the curve between -1.5 and 1.5 is approximately 0.8664 or 86.64%.

Suppose that y varies directly with x and y = 3 when x = 9. What is y when x = 18?
Answer:
y = 6
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in y = 3 and x = 9, and solve for k
y = kx
3 = k(9)
1/3 = k
So, the equation is y = 1/3x
Plug in 18 as x and solve for y
y = 1/3x
y = 1/3(18)
y = 6
So, when x = 18, y = 6

Answer:
h = 403.92in or 1026cm
Step-by-step explanation:
Given
Let x represent the density of mercury, and y the density of water.
[tex]y = 13.5x[/tex]
[tex]Mercury\ barometer =76cm[/tex] or [tex]Mercury\ barometer =29.92in[/tex]

. A rectangle has its base on the x-axis and its upper two vertices on the semi-circle y = V1 - 32. What is the largest area the rectangle can have? 1 6 1
The largest area the rectangle can have is -1024 square units.
To solve the given problem, follow the steps given below:
Step 1: Sketch the given graph on a coordinate plane as shown below:
Step 2: Let's assume that the base of the rectangle is x units and its height is y units.
Step 3: As the base of the rectangle is on x-axis, we have the length of the base as the x-coordinate of the upper two vertices of the rectangle.
Now, the x-coordinate of the upper two vertices of the rectangle lie on the given semicircle whose equation is y = V1 - 32.
So, we can write:
y = V1 - 32x^2 = (y + 32)^2 ⇒ x^2 = y^2 + 64y + 1024
Step 4: Now, we can write the area of the rectangle as: A = base × height= x × y
Using the value of x from equation (1), we get: A = (y^2 + 64y + 1024)1/2 y
So, we have an equation for area in terms of y. Let's differentiate it with respect to y to find the maximum value of A. dA/dy = (y^2 + 64y + 1024)-1/2 (2y + 64)
By equating dA/dy = 0, we get: 2y + 64 = 0y = -32
Substituting the value of y in equation (2), we get:x^2 = 1024 ⇒ x = ±32
The given rectangle lies in the first quadrant.
Hence, the length of the base of the rectangle is x = 32 units.
So, we have the dimensions of the rectangle as length = 32 units and breadth = height = y = -32 units.
However, as the length and breadth of the rectangle cannot be negative, we cannot consider the negative value of y.
Therefore, the maximum area of the rectangle is: A = base × height= 32 × (-32)= -1024 sq. units
Hence, the largest area the rectangle can have is -1024 square units.

In a particular region, 6% of the population is thought to have a certain disease. A standard diagnostic test has been found to correctly identify 91% of the people who have the disease. However, the test also incorrectly diagnoses 8% of those who do not have the disease as having the disease (in other words, the person does not have the disease but the test tells them that they do). A randomly selected person in the region is tested for the disease. (a) What is the probability the test comes back positive
Answer:
The positive predictive value ≈ 30.012%
Step-by-step explanation:
(a) The given percentage of the people in the region that have the disease, P(D) = 6% = 0.06
The percentage people correctly identified as having the disease by the standard diagnostic test = 91%
The percentage of people incorrectly identified as having the disease by the standard diagnostic test, P(T + |H) = 8%
Therefore, the sensitivity of the test, P(T + |D) = 0.91
The specificity of the test, P(T - |H) = 1 - 0.08 = 0.92
Therefore, the probability that a person is healthy, P(H) = 1 - 0.06 = 0.94
Therefore, in a population of 1,000 people, 60 people have the disease, with a sensitivity of 91%, the test will correctly pic 0.91×66 = 60.06 people correctly with the disease and 0.91 × 940 = 855.4 people without the disease
The number of non-diseased that test positive by the test is 0.08 × 1000 = 80 people which are false positives
Therefore, the number of diseased diagnosed as negative is 0.08 × 60 = 4.8
Therefore, we have;
[tex]\begin{array}{cccc}&Deseased&Non-diseased& Diseased + Non-diseased\\Test \ +ve&60.06&80& 140.06\\Test \ -ve&4.8&855.4&\end{array}[/tex]
The positive predictive value = Diseased +ve/(Diseased +ve + Non-diseased +ve)
[tex]The \ positive \ predictive \ value = \dfrac{Diseased +ve}{Diseased +ve + Non-diseased +ve} \times 100[/tex]
Therefore;
The positive predictive value = 60.06/(60.06 + 140.06) × 100 ≈ 30.012%
A cylinder has been cut out of a solid. Find the volume of the remaining solid. Round answer to the nearest tenth.
Answer:
98.19
Step-by-step explanation:
Volume of whole cube minus volume of cylinder. volume of cylinder is pi x r^2 x h
The volume of remaining solid is 46.44 in³
What is Volume?Volume is the measure of the capacity that an object holds.
For example, if a cup can hold 100 ml of water up to the brim, its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains. The best way to visualize volume is to think of it in terms of the space.
How To Calculate the Volume?Here are the steps to calculate volume of any solid shape:
Identify all the given parameters that are useful and are required to substitute in the respective volume formula. Such as the radius to be 'r' and height to be 'h', the slant height, diameter, etc.Make sure all the parameters are of the same units.Substitute the values in the volume formula of the respective shapes.Write the units as cubic units.edge= 6
Volume of cube= l³
= 6*6*6
=216 in³
Now, Volume of cylinder
=πr²h
= 3.14 * 3 * 3 * 6
=169.56 in³
Volume of remaining solid= 216- 169.56

The relationship between x and y is positive. b. The relationship between x and y is negative. c. As x decreases, y increases. d. None of the answer options is correct.
The least squares regression line y-3 x-3 is (a) "The relationship between x and y is positive."
To get the area under the standard Normal curve corresponding to Z < 0.75, we can use the standard Normal distribution tables. The tables provide the cumulative probability up to a given Z-score.
Looking up the value of 0.75 in the standard Normal distribution table, we find that the corresponding area is approximately 0.7734.
Therefore, the answer is (b) 0.7734.
Regarding the least squares regression line y = 3x - 3, we can make the following observations:
a. The relationship between x and y is positive: This is true because the coefficient of x (3) is positive, indicating a positive relationship between x and y.
b. The relationship between x and y is negative: This is false because the coefficient of x (3) is positive, indicating a positive relationship between x and y.
c. As x decreases, y increases: This is false because as x decreases, y will also decrease based on the equation y = 3x - 3.
d. None of the answer options is correct: This is false because option (a) "The relationship between x and y is positive" is correct.

the difference between a low-cost provider strategy and a focused low-cost strategy is
The difference between a low-cost provider strategy and a focused low-cost strategy lies in their scope and target market. A low-cost provider strategy aims to achieve a cost advantage over competitors while targeting a broad market segment.
A low-cost provider strategy involves offering products or services at a lower cost compared to competitors while targeting a broad customer base. The focus is on achieving economies of scale, operational efficiencies, and cost reduction across the value chain to deliver products or services at competitive prices. This strategy aims to attract a large customer base through cost advantages and can be employed in various industries.
In contrast, a focused low-cost strategy narrows down the target market to a specific segment or niche. Instead of targeting a broad market, the company focuses on serving a particular group of customers with specialized needs or preferences. By understanding the unique requirements of this specific segment, the company can tailor its offerings and operations to provide lower costs, thereby gaining a competitive edge within that niche market. This strategy allows for a more concentrated effort and customization to cater to the specific demands of the chosen market segment.
