Step-by-step explanation:

85-25%= $63.75

Answer:

- 1/40

Step-by-step explanation:

-0.025 = -0.025/1

we have 3 numbers after the decimal point so we multiply both numerator and denominator by 1000

( -0.025 x 1000)/(1 x 1000) = -25/1000

reduce the above fraction by dividing both numerator and denominator by the greatest common divisor between them. in this case GCD (25,1000) = 25.

(-25/25)/(1000/25) = - 1/40

Answer:

y=-6.

Step-by-step explanation:

1) the condition f(-1)=-6 and f(4)=-6 mean points A and B have coordinates (-1;-6) and (4;-6);

2) the points A and B has the same y-coordinate, it means, the required line is parallel to the x-axis and the required function is: y=-6.

P.S. the suggested way is not the only one.

The linear function f is f(x) = -6.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(-1) = -6

f(4) = -6

The linear function f can be in the form of f(x) = mx + c.

Now,

m = (-6 + 6) / (4 - 1)

m = 0/3

m = 0

Now,

f(-1) = -6

x = -1

f(x) = mx + c

f(-1) = 0 x -1 + c

-6 = 0 + c

c = -6

Now,

f(x) = -6

Thus,

The function f is a constant function.

f(x) = -6

Answer:  32.50  [No $ sign as per the directions]

Step-by-step explanation:

The graph appears as a straight line.  That means we can pick any two points and calculate the slope, m, for the equation of a straight line:  y = mx + b

We can pick any two points, so I'll pick two that do not require interpretation of the graph.  Points (0,0) and (8,20) look good since we can feel relatively confident that the line crosses those two points since they fall on the graph marking lines.

Slope is Rise/Run, or the change in y per the change in x.  For these two points, we have:

Rise = (20 - 0) or 20

Run =    (8 - 0) or 8

The slope is Rise/Run.  20/8, or 2.5

[The units for the slope are $/lb, but units are to be left out of the answer]

The equation is now y = 2.5x + b

b is the y-intercept, the value of y when x = 0.  We can see that y = o when x = 0, so b is zero.

The final equation is y = 2.5x

Use x = 13 lbs to find the cost of 13 lbs of blueberries.

It is 13*2.5 = 32.50

Answer:

Step-by-step explanation: you would start with a dot on the y-axis at -2, then you would go up 2 and over 5 cuz the slope is 2/5. just keep doing this and you’ll have your graph

Notice that 100 is 20 less than 120, or equivalently 2 standard deviations σ below the mean µ. So

P(x ≥ 100) = P(x ≥ µ - 2σ)

Recall the empirical rule for normal distributions (these are true for any mean µ and s.d. σ):

• P(µ - σ ≤ x ≤ µ + σ) ≈ 0.65

• P(µ - 2σ ≤ x ≤ µ + 2σ) ≈ 0.95

• P(µ - 3σ ≤ x ≤ µ + 3σ) ≈ 0.997

The probability we want is the same as

P(x ≥ µ - 2σ) = P(µ - 2σ ≤ x ≤ µ + 2σ) + P(µ + 2σ ≤ x)

or

P(x ≥ µ - 2σ) ≈ 0.95 + P(µ + 2σ ≤ x)

which is clearly some number larger than 0.95, so A must be correct.

Suppose a normal distribution has a mean of 120 and a standard deviation, P(x >= 100) is 0.975. Option A. This is further explained below.

Generally, normal distribution is simply defined as a function that displays the dispersion of numerous unknown parameters as a symmetrical bell-shaped graph.

In conclusion, based on the function

P(x ≥ µ - 2σ) ≈ 0.95 + P(µ + 2σ ≤ x)

the function P(x >= 100) is 0.975

Simplify the arithmetic:

2/3 · x =-13-9

Simplify the arithmetic:

2/3 · x = -22

Multiply both sides by inverse fraction 3/2:

2/3x ·3/2= -22 ·3/2

Group like terms:

 2/3 ·3/2x= -22 ·3/2

Simplify the fraction:

x=-22 · 2/3

Multiply the fractions:

x= -22·2/3 ÷2

Simplify the arithmetic:

x = -33

Step-by-step explanation:

ln(x) + ln(x + 25) = 0

ln(x(x + 25)) = 0

ln(x² + 25x) = 0

ln(x² + 25x) = ln(1) , x ≥ 0

x² + 25x = 1

x² + 25x + 625/4 = 1 + 625/4

(x + 25/2)² = 629/4

x + 25/2 = ±√(629/4)

x = ( -25 ±√629)/2

x = (-25 - √629)/2 atau ( -25 + √629)/2

(-25 - √629)/2 ≥ 0 NOT PROVED

(-25 + √629)/2 ≥ 0 PROVED

Answer:

Make a line connecting points (0,0) (1,5) and (-1,-5)

Step-by-step explanation:

Okay, so you have to start your first point at (0,0), which is the origin, because there is no y-intercept in the equation.

Next you use slope, Rise/Run to plot your next point. In the equation y=mx+b, the slope is in m. So in y=5x, the slope is 5/1 .

So, you're going to move up 5 from the origin and move to the right once, which will give you the point (1,5).

If you need another point to make a line go the opposite way from the origin. So we would go down 5 and left 1. That would give us the point (-1,-5)

The dimensions of the border is 1.5 feet for the garden

A rectangle is a quadrilateral with four sides and four angles in which opposite sides are equal and parallel.

The area of a rectangle = Length * breadth

Given that length of garden = 16 ft., width of garden = 12 ft.

It is surrounded by a mulch of width x, hence:

New length = 16 + x + x = 16 + 2x

New width = 12 + x + x = 12 + 2x

The area of garden = 16 + 2x(12 + 2x) = 192 + 56x + 4x²

Since the maximum area is 285 ft, hence:

192 + 56x + 4x² = 285

4x² + 56x - 93 = 0

x = 1.5 feet

Step-by-step explanation:

1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.

What is geometry ?

Geometry is the branch of mathematics focused on the relationships and characteristics of solids, surfaces, solids, and other such objects.

Given, we must describe the first stage , which will be the process of copying a line segment, which ensures that the new line segment is the same length as the original line segment. An angle and a segment must be copied as a first step. The picture gives a description of the copying construction.

The width of the compass must then be adjusted to the segment length. The new angle will now be consistent with the original angle. This is the next step.

Making a perpendicular line is the next step. Here, it is demonstrated how to draw a line through a point that is perpendicular to the given line.

Therefore , 1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.
