Answer:
Programmed
Step-by-step explanation:
Programmed Decisons may be classified as those actions which are routinely carried out or performed based on existing rules and protocol. In programmed decision making, the rules are in place, therefore once the criteria or requirement for which the rule or routine is to be enforced arises, programmed Decisons are made. In the scenario, the superintendent required that a programmed Decison be made in cases or situations where enrollment increases by 35 student beyond capacity, Hence, with this, every time this occurs the additional teachers will be hired.
Do oddsmakers believe that teams who play at home will have home field advantage? Specifically, do oddsmakers give higher point spreads when the favored team plays home games as compared to when the favored team plays away games? Two samples were randomly
Complete question is;
Do oddsmakers believe that teams who play at home will have home field advantage? Specifically, do oddsmakers give higher point spreads when the favored team plays home games as compared to when the favored team plays away games?
Two samples were randomly selected from three complete National Football League seasons (1989, 1990, and 1991). The first sample consisted of 50 games, where the favored team played in a home game, while the second sample consisted of 50 games, where the favored team played in an away game. The oddsmakers’ point spreads (which are the number of points by which the favored team is predicted to beat the weaker team) were then collected.
If µ1 and µ2 represent the mean point spread for home games and away games, respectively, which of the following is the appropriate.
A) H0: μ1 - μ2 = 0
Ha: μ1 - μ2 < 0
B) H0: μ1 - μ2 = 0
Ha: μ1 < μ2
C) H0: μ1 - μ2 > 0
Ha: μ1 - μ2 = 0
D) H0: μ1 - μ2 = 0
Ha: μ1 - μ2 > 0
E) None of the above
Answer:
D) H0: μ1 - μ2 = 0
Ha: μ1 - μ2 > 0
Step-by-step explanation:
We want to find out if oddsmakers give higher point spreads when the favored team plays home games as compared to when the favored team plays away games.
Now, since µ1 and µ2 represent the mean point spread for home games and away games, respectively;
It means we want to find out if µ1 > µ2 as the alternative hypothesis.
Thus, alternative hypothesis is;
Ha: µ1 - µ2 > 0
Meanwhile null hypothesis assumes that equal point spreads are given when the favored team plays home games as well as when the favored team plays away games.
Thus, null hypothesis is;
H0: μ1 - μ2 = 0
The only correct option is D.

Find the value of x to the nearest tenth.
Answer:
Step-by-step explanation:
Using Pythagoreus Theorem
In the smaller rectangle
2²+4² = h²
20 = h²
h = √20
h = 2√5
Therefore two sides of the rectangle will 2√5
No using pythagoreus theorem in the bigger triangle
x² + (2√5)² = 9²
x² = 9² - (2√5)²
x² = 81 - 20
x = √61
x = 7.8102496759
When rounded off to nearest tenth the hundreth digit is in 0-5 range
x = 7.81

The weight of an object on the moon is
1/6 of its weight on Earth. If a moon rock
weighs 20.5 lb on Earth, how much did
the moon rock weigh on the moon?
Answer:
1/6 = 0.16 = 16%
restate the question: 16% of 20.5 is what? multiply: 20.5*.16 = 3.28 now, to find the weight of the object on the moon, subtract 16% from 20.5. 16% of 20.5 is 3.28 20.5-3.28 = 17.22 = 17 22/100 = 17 11/50
the weight of the object is 17 11/50 pounds on the moon.

Answer:
[tex]Max\ z = 1[/tex]
[tex]Min\ z = -9[/tex]
Step-by-step explanation:
Given
[tex]z = 4x + 5y[/tex]
[tex]x \ge -1[/tex]
[tex]y \le 2x +3[/tex]
[tex]y \le -1[/tex]
Required
The maximum and minimum of z
To do this, we make use of the graphical method
See attachment for graphs of
[tex]x \ge -1[/tex]
[tex]y \le 2x +3[/tex]
[tex]y \le -1[/tex]
The corner points of the function are:
[tex](x,y) = (-1,1)[/tex]
[tex](x,y) = (-1,0)[/tex]
[tex](x,y) = (-1,-1)[/tex]
We have:
[tex]z = 4x + 5y[/tex]
Calculate z with the above values
[tex]z = 4(-1) + 5(1) = 1[/tex]
[tex]z = 4(-1) + 5(0) = -4[/tex]
[tex]z = 4(-1) + 5(-1) = -9[/tex]
So, we have:
[tex]Max\ z = 1[/tex]
[tex]Min\ z = -9[/tex]

Answer:
D
Step-by-step explanation:
The sides of a rhombus are congruent , then
13b - 9 = 3b + 4 ( subtract 3b from both sides )
10b - 9 = 4 ( add 9 to both sides )
10b = 13 ( divide both sides by 10 )
b = 1.3
The diagonals are perpendicular bisectors of each other , then
14a + 20 = 90 ( subtract 20 from both sides )
14a = 70 ( divide both sides by 14 )
a = 5
Thus c = a + b = 5 + 1.3 = 6.3 → D

Answer:
shift of 1 unit to the right
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Given the parent function is y = x² , then
y = (x - 1)² is a shift to the left of 1 unit of the parent function

The distance is always the opposite of the difference.
The distance is exactly the difference.
The distance is the absolute value of the difference.
The distance is not related to difference.
NEED HELP FOR EDGUNITY
Answer:
C. The distance is the absolute value of the difference.Step-by-step explanation:
See the table made based on the given values.
It is easy to note that the numbers in the distance column are same as numbers in the a - b column but all numbers being positive.
So we can say that:

A point on the line is-
A)(-4,-1)
B)(4,1/2)
C)(1/2,-1)
D)(1,4)
Answer:
C
D
Step-by-step explanation:
Point slope form is written in
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Looking at the values we have m = 1/2 and x1 = 1, y1 = 4.
Therefore the slope is 1/2 and the point is (1,4)

In geometry, several transformations (such as dilation, rotation, reflection, etc.) can be applied to move a parent function to a new function. The function that represents g(x) is [tex]g(x) = 3|x|[/tex]
Given that:
[tex]f(x) = |x|[/tex]
First, we reflect over the y-axis.
The rule of this transformation is: [tex](x,y) \to (-x,y)[/tex]
So, the function becomes
[tex]f'(x) = |-x|[/tex]
[tex]f'(x) = |x|[/tex]
Next, shrink horizontally by 1/3
The rule of this transformation is: [tex](x,y) \to (\frac{x}{a},y)[/tex]
Where:
[tex]a = \frac{1}{3}[/tex]
So, we have:
[tex]g(x) = |\frac{x}{1/3}|[/tex]
[tex]g(x) = |3x|[/tex]
[tex]g(x) = 3|x|[/tex]
Hence, the function that represents g(x) is [tex]g(x) = 3|x|[/tex]

A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 24 ft long and 16 ft wide.
Find the area of the garden.
Answer: Using width as diameter=32π Using length as diameter=72π
*I included both possibilities since I didn't see a picture of the way in which the semicircle and rectangle were joined.*
Step-by-step explanation:
In order to solve, you have to know the formula for area of a circle which is A=πr^2 (pi*radius to the 2nd power)
The problem does not give us the radius, but we know that radius is half of the diameter.
To find the diameter, we have to use the side measurement of the rectangle and divide it by 2 to find the radius.
Next, we increase the radius to the 2nd power, giving us the radius of a whole circle.
Finally, we have to divide that by 2 since it's a semi circle otherwise known as half of a circle.
I put the answer in terms of pi since that's the most accurate, but if the question specifically instructs it, you can calculate part of the irrational decimal and round to a certain place value.
