Step-by-step explanation:

First let's find the equation of the doted line.

Notice that the line is crossing these points:

● (0,1)

● (1,2)

The equation of the line has the following form:

● y = ax+c

C is the y-intercept wich is given by the output of 0.

Notice that the output of 0 is 1.

● y = ax+1

● a = rise / run = (2-1)/(1-0) = 1

So y = x + 1

■■■■■■■■■■■■■■■■■■■■■■■■■■

Notice that the line divide the plan into 2 areas.

● y > x+1 => x+1-y < 0

● y < x+1 => x+1 -y > 0

To khwo wich one that represent the shaded area take a point and replace x and y by its coordinates

● (-1,2)

● -1+1-2 = 0-2 = -2

It is a negative value so the inequality is

● y > x+1

Answer:

Step-by-step explanation:

Given

2^x [(x+1)³ -1] = 2^x - (x+1)³ + 1

Lep p = 2^x, and q = (x+1)³ - 1

Then the original equation becomes

pq = p - q

p - q - pq = 0

p(1 - q) - q = 0

p = q/(1 - q)

2^x = [(x+1)³ - 1]/[-(x+1)³]

2^x = [1 - (x+1)³]/[(x+1)³]

2^x = (x+1)^(-3) - 1

Answer:

Step-by-step explanation:

Since the base of the pyramid PABCD is a rectangle, the shape in question is a rectangular based pyramid. Volume of a rectangular based pyramid is expressed as V = 1/3 * Base Area * Height of the pyramid.

Given a rectangle ABCD with AB = 8 and BC = 4, the area of the rectangle will be equivalent to the base area of the pyramid.

Base Area = Length * Breadth

Base Area = AB * BC

Base Area = 8*4 = 32

If [tex]\overline{PA}\perp \overline{AD}\ and \ \overline{PA}\perp \overline{AB}[/tex], and PB = 17, then the height of the pyramid is PB = 17.

Volume of the pyramid = 1/3 * 32 * 17

Volume of the pyramid = 1/3 * 544

Volume of the rectangular based pyramid = 181.33

Answer:

11 over 13

Step-by-step explanation:

first, you deal with multiplication;

x = -12 + 14 - 12x + 13

second, deal with addition;

x = -2 - 12x + 13

third, take -12 to the other side then the negative changes to positive;

12x + x = -2 + 13

fourth, add them then simplify;

13x = 11

ans is 11 over 13

Answer:

E. [tex]y=\frac{1}{3}x[/tex]

Step-by-step explanation:

Take the two points shown:

[tex](0,0)(6,2)[/tex]

Use these to make an equation in slope-intercept form:

[tex]y=mx+b[/tex]

m is the slope and b is the y-intercept (where x is equal to 0).

Use the slope formula:

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}[/tex]

Rise over run is the change in the y-axis over the change in the x-axis, otherwise known as the slope. Insert coordinate points:

[tex](0_{x1},0_{y1})\\\\(6_{x2},2_{y2})\\\\\frac{2-0}{6-0}[/tex]

Simplify:

[tex]\frac{2-0}{6-0} =\frac{2}{6} =\frac{1}{3}[/tex]

The slope is [tex]\frac{1}{3}[/tex]. Insert this into the equation:

[tex]y=\frac{1}{3}x+b[/tex]

Now find the y-intercept. Take one of the coordinate points and insert:

[tex](6_{x},2_{y})\\\\2=\frac{1}{3}(6)+b[/tex]

Solve for b. Simplify multiplication:

[tex]\frac{1}{3}*\frac{6}{1}=\frac{6}{3}=2\\\\ 2=2+b[/tex]

Use reverse operations to isolate the variable:

[tex]2-2=2-2+b\\\\0=b[/tex]

The y-intercept is equal to 0. Insert this into the equation:

[tex]y=\frac{1}{3}x+0[/tex]

or

[tex]y=\frac{1}{3}x[/tex]

Answer: ABCD is a parallelogram.

Step-by-step explanation:

First we plot these point on a graph as given in attachment.

From the attachment we can observe that AD || BC || x-axis .

also, AB ||CD, that will make ABCD a parallelogram ,  but to confirm we check the property of parallelogram "diagonals bisect each other" , i.e . "Mid point of both diagonals are equal".

Mid point of AC= [tex](\dfrac{-5+4}{2},\dfrac{2+5}{2})=(\dfrac{-1}{2},\dfrac{7}{2})[/tex]

Mid point of BD= [tex](\dfrac{-3+2}{2},\dfrac{5+2}{2})=(\dfrac{-1}{2},\dfrac{7}{2})[/tex]

Thus, Mid point of AC=Mid point of BD

i.e. diagonals bisect each other.

That means ABCD is a parallelogram.

Answer:

The frequency distribution does not appear to be normal.

Step-by-step explanation:

The data provided is as follows:

S = {0.38 , 0 , 0.22 , 0.06 , 0 , 0 , 0.21 , 0 , 0.53 , 0.18 , 0 , 0 , 0.02 , 0 , 0 , 0.24 , 0 , 0 , 0.01 , 0 , 0 , 1.28 , 0.24 , 0 , 0.19 , 0.53 , 0 , 0, 0.24 , 0}

It is provided that the first lower class limit should be 0.00 and the class width should be 0.20.

The frequency distribution table is as follows:

Class Interval  Count

 0.00 - 0.19            21

 0.20 - 0.39             6

 0.40 - 0.59             2

 0.60 - 0.79             0

 0.80 - 0.99             0

  1.00 - 1 . 19             0

  1.20 - 1. 39             1

The frequency distribution does not appear to be normal. This is because the frequencies does not start and end at almost equivalent points and the mid-distribution does not consist of the highest frequency.

Thus, the frequency distribution does not appear to be normal.

Answer:

  C)  Reflection about the origin

Step-by-step explanation:

DE points to the right and slightly down. D'E' points to the left and slightly up. The segments are parallel, not perpendicular, so represent a rotation of 180°, not 90°. If the figure were subject only to translation, these segments would point in the same direction.

The transformation is a reflection about the origin (C). (This is equivalent to a rotation of 180°.)

Step-by-step explanation:

Answer:

x = 11 or 3

Step-by-step explanation:

f(x) = (1/2)(x- 7)² – 8​

to find the zeros, we equate f(x) = 0

f(x) = 0

(1/2)(x- 7)² – 8​ = 0      (add 8 to both sides)

(1/2)(x- 7)² = 8     (multiply both sides by 2)

(x- 7)² = (8)(2)

(x- 7)² = 16

x-7 = ±√16

x-7 = ±4

hence,

x - 7 = 4

x = 4 + 7

x = 11

or

x - 7 = -4

x = -4 +7

x = 3

Answer:

C

Step-by-step explanation:

The set of data will only become more narrow when the standard deviation is decreased, so D isn't correct. The data isn't going to shift directions unless there's a translation, so A and B are both out. That leaves us with C. The opposite of answer D.

Answer:

C. It produces a wider range of probable values

Step-by-step explanation:

The set of data that we have cannot shift in directions unless there is a translation, so therefore, A and B are both out. The set of data would become smaller when the standard deviation is decreases so therefore, D isn't correct. So, that leaves us with only one answer.

C. It produces a wider range of probably values.

This question is incomplete, here is the complete question:

Specifications for a part for a DVD player state that the part should weigh between 25.2 and 26.2 ounces. The process that produces the parts has a mean of 25.7 ounces and a standard deviation of .25 ounce. The distribution of output is normal. Use Table-A

a) What percentage of parts will not meet the weight specs? (Round your "z" value and final answer to 2 decimal places.

b) Within what values will 95.44 percent of sample means of this process fall, if samples of n = 8 are taken and the process is in control (random)

Answer:

a) What percentage of parts will not meet the weight specs = 4.56%

b) values within which 95.44 percent of sample means of this process falls are;

UCL = 25.88 ounces

LCL = 25.52 ounces

Step-by-step explanation:

Given that;

Mean u = 25.7 ounces

Std deviation = 0.25 ounces

a)

Z-score (Upper) = (X- u) / s = (26.2 - 25.7) / 0.25 = 2

Z-score (Lower) = ( 25.2-25.7 ) / 0.25 = -2

using the T - table

For Z = 2.0

the area in the tail of the curve to the right of the mean (upper) = 0.4772

therefore;

Number of defective = 0.5000 - 0.4772 = 0.0228

These are errors on one side of normal distribution.

To get the total error, we say

Total error = 2 × 0.0228

Total error = 0.0456 ≈ 4.56% ( 2 decimal place )

b)

given that;

n = 8,

standard deviation = 0.25 ounce

Standard deviation of X = Std deviation / √n

= 0.25 /√8 = 0.088

Now for 95.44% of confidence interval, Z = 2

UCL = Mean + Z × Standard deviation of X

= 25.7 + 2 × 0.088

= 25.88 ounces

LCL = Mean - Z × Standard deviation of X

= 25.7 - 2 × 0.088

= 25.52 ounces

Answer:

16.50 gallons per minute

Step-by-step explanation:

Because this is a proportional function, we can set up the equation y = kx, where k is the constant of proportionality. By plugging in one point (and this point can be any point provided by the table), we can use the equality k = y/x to find the proportionality constant. If we plug in the information at 1 minute, we get 16.50/1 = 16.5

The constant of proportionality is same for all the rows that is 16.50 gallons per minute.

WE can calculate the Constant of proportionality as;

Constant of proportionality = no of gallons of water per 1 minute.

we have 16.50 gallons of water per 1 minute and 24.75 gallons of water in 1.5 minutes.

In 1 minute, we will have,

24.75 ÷ 1.5 = 16.50 gallons

Similarly,

33 gallons in 2 minutes. In 1 minute, we will have,

33 ÷ 2 = 16.50 gallons.

We can see that there seems to be the same constant of proportionality for the 2nd and 3rd row, that is 16.50.

Thus, a relationship between gallons of water (w) and time (t), considering the constant, 16.50, can be written as:

w = 16.50t

Hence, the constant of proportionality, 16.50, is same for all rows.

Startup = $116000

Cost per item = $25

Equation: 25q + 116000

Required

Determine the cost of producing 8900 items

The question implies that q = 8900

To solve further, we have to substitute 8900 for q in the given equation

Equation = 25q + 116000 becomes

[tex]Cost = 25 * 8900 + 116000[/tex]

[tex]Cost = 222500 + 116000[/tex]

Answer:

The respiratory system extends from the nose and upper airway to the alveolar surface of the lungs, where gas exchange occurs. Inhaled tobacco smoke moves from the mouth through the upper airway, ultimately reaching the alveoli. As the smoke moves more deeply into the respiratory tract, more soluble gases are adsorbed and particles are deposited in the airways and alveoli. The substantial doses of carcinogens and toxins delivered to these sites place smokers at risk for malignant and nonmalignant diseases involving all components of the respiratory tract including the mouth.
