Answer:
A 1 in 4 chance or a probability of 0.25
Step-by-step explanation:
There is only 3 months that start with J and 12 months in a year so simplify 3/12 you get 1/4 or 0.25

The function h(t) = - 16t2 + 48t + 160 can be used to model the height, in feet, of an object t
seconds after it is launched from the top of a building that is 160 feet tall.
Two other forms of the function are:
h(t) = -16(t - 5)(t+2)
h(t) = -16(t-1.5)2 +196
Which value of the function represents the maximum height of the object?
A h(0)
B. h(1.5)
C. h(2)
D. h(5)
Answer:
answer is c because you have to put in the 2 and get -16
The following probability distributions of job satisfaction scores for a sample of information systems (IS) senior executives and middle managers range from a low of 1 (very dissatisfied) to a high of 5 (very satisfied).

2. What is the expected value of the job satisfaction score for middle managers (to 2 decimals)?
3. Compute the variance of job satisfaction scores for executives and middle managers (to 2 decimals).
4. Compute the standard deviation of job satisfaction scores for both probability distributions (to 2 decimals).
5. What comparison can you make about the job satisfaction of senior executives and middle managers?
Answer:
1.)E₁ = 4,03
2) E₂ = 3,85
3) σ₁² = 1,23
4)σ₂² = 1,14
5)σ₁ = 1,11
6)σ₂ = 1,07
5 ) Distribution of senior executive and Middle Manager look pretty similar , diference in median 0,18 and difference in standard deviation 0,04
Step-by-step explanation:
1.-Expected value of the job satisfaction score for senior executive
E₁, variance σ₁ and standard deviation σ₁ and expected value of the job satisfaction score for Middle Manager E₂ variance σ₂ and standard deviation σ₂
E(X) = ∑ ( xi *f(xi)

2 0,09 0,1
3 0,03 0,12

∑ xi*f(xi) = 1*0,05 + 2 *0,09 + 3*0,03 + 4 * 0,44 + 5 * 0,39
E₁ = 0,05 + 0,18 + 0,09 + 1,76 + 1,95
1.)E₁ = 4,03
2.) ∑ xi*f(xi)
E₂ = 1* 0,04 + 2 * 0,1 + 3*0,12 + 4*0,45 +5*0,29
E₂ = 0,04 + 0,2 + 0,36 + 1,8 + 1,45
E₂ = 3,85
2 ) E₂ = 3,85
3) Variance of job satisfaction scores for senior executives.
x² f(x) x²* f(x)

4 0,09 0,36
9 0,03 0,27
16 0,44 7,04
25 0,39 9,75
σ₁² = [ ∑ x²*f(x) ] - μ² ∑ x²*f(x) = 17,47
In this case μ = E μ² = ( 4,03)² = 16,24
For senior executives: σ₁² = 17,47 - 16,24 = 1,23
σ₁² = 1,23
And standard deviation σ₁ = 1,11
For Middle managers
x² f(x) x²* f(x)
1 0,04 0,04
4 0,1 0,4
9 0,12 1,08
16 0,45 7,2
25 0,29 7,25
∑ x²*f(x) = 15,97
σ₂² = 15,97 - (3,85)² = 15,97 - 14,82
σ₂² = 1,14
σ₂ = √1,14 = 1,07
5 ) Distribution of senior executive and Middle Manager look pretty similar , diference in median 0,18 and difference in standard deviation 0,04

Answer:
∠4 = 120°∠5 = 80°Step-by-step explanation:
Angle 5 is the third angle of the triangle whose other two angles are 45° and 55°. So, its measure is ...
∠5 = 180° -45° -55°
∠5 = 80°
__
This figure cannot be solved for angle 4 unless we assume the horizontal lines are parallel. Using the angle numbers as vertex designators, angle 245 and the one marked 45° are alternate interior angles, so are congruent. Angle 4 is vertical with the angle that is the sum of angle 245 and 75°, so we have ...
∠4 = 75° +45°
∠4 = 120°

Michael bakes a soft pretzel and a loaf of bread. Use the system of equations to find c, the amount of flour, in cups, needed for the soft pretzel, and b, the amount of flour, in cups, needed for the loaf of bread. Show your work.
b = 24c
(1/4)b + 4c = 5/4
The amount of flour needed for soft pretzel is c = 1/8 and the amount of flour needed for the loaf of bread is b = 3.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given system of equations,
b = 24 c and
[tex]\frac{1}{4}[/tex] b + 4c = [tex]\frac{5}{4}[/tex]
Substitute b = 24 c in the second equation.
[tex]\frac{1}{4}[/tex] (24 c) + 4c = [tex]\frac{5}{4}[/tex]
6c + 4c = [tex]\frac{5}{4}[/tex]
10 c = [tex]\frac{5}{4}[/tex]
c = [tex]\frac{5}{4}[/tex] × [tex]\frac{1}{10}[/tex] = [tex]\frac{1}{8}[/tex]
b = 24c = 24 / 8 = 3
Hence c = 1/8 and b = 3 in cups.

67. The line contains the point (4,0) and is parallel
to the line defined by 3x = 2y.
Answer:
[tex]y=\frac{3}{2} x-6[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form:[tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines will always have the same slope but different y-intercepts.1) Determine the slope of the parallel line
Organize 3x = 2y into slope-intercept form. Why? So we can easily identify the slope, m.
[tex]3x = 2y[/tex]
Switch the sides
[tex]2y=3x[/tex]
Divide both sides by 2 to isolate y
[tex]\frac{2y}{2} = \frac{3}{2} x\\y=\frac{3}{2} x[/tex]
Now that this equation is in slope-intercept form, we can easily identify that [tex]\frac{3}{2}[/tex] is in the place of m. Therefore, because parallel lines have the same slope, the parallel line we're solving for now will also have the slope [tex]\frac{3}{2}[/tex] . Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{3}{2} x+b[/tex]
2) Determine the y-intercept
[tex]y=\frac{3}{2} x+b[/tex]
Plug in the given point, (4,0)
[tex]0=\frac{3}{2} (4)+b\\0=6+b[/tex]
Subtract both sides by 6
[tex]0-6=6+b-6\\-6=b[/tex]
Therefore, -6 is the y-intercept of the line. Plug this into [tex]y=\frac{3}{2} x+b[/tex] as b:
[tex]y=\frac{3}{2} x-6[/tex]

Determine which two numbers come next in the sequence 5,5,10,15,25, __, __
The two numbers that come next in the sequence 5,5,10,15,25, are 40 and 65.
How can the two numbers that come next in the sequence be calculated?To calculate this , You can figure it out by taking the first number, which is 5. However, since the previous number is 0, the sum is 5, and you proceed in the same manner.
5 + 5 = 10
(5 + 10) = 15
(10 + 15) = 25
(15 + 25) = 40
(25 + 40) = 65

Step-by-step explanation:
A recreational area is formed by a rectangular shaped pool and a cement patio surrounding the pool. the pool has a length of 3x-3 meters and a width of 2x+7 meters. The patio extends x meters around to pool, on all sides of the pool. Write a polynomial expression that gives the total area of the recreational area.
The total area of the recreational area can be represented by the polynomial expression 26x² + 57x + 35.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
The area of the rectangular pool is given by its length times its width, so the area of the pool is (3x - 3) meters × (2x + 7) meters = (6x² + x - 21) square meters.
The area of the patio is given by the length of the pool plus twice the extension (x) on each side, times the width of the pool plus twice the extension on each side, so the area of the patio is (3x - 3 + 2x) meters × (2x + 7 + 2x) meters = (5x + 4) × (4x + 14) = 20x² + 56x + 56 square meters.
The total area of the recreational area is the sum of the areas of the pool and the patio, so it can be represented by the polynomial expression:
20x² + 56x + 56 + 6x² + x - 21 = 26x² + 57x + 35
