A type of Conic where the plane is tilted and intersects only on one cone to form a bounded curve.

Answer:

The correct option is b.

Step-by-step explanation:

Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the absolute variability of the distribution of values.

The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.

It is provided that the  standard deviation of the distribution of house age is about 16 years.

The standard deviation of 16 years imply that the age for all the houses in the sample is 16 years from the mean.

Thus, the correct option is b.

Answer: A

Step-by-step explanation:

For this problem, we would distribute the outer exponent to each exponent inside. Once we distribute, we multiply the exponents together.

[tex]2^\frac{12}{5} *9^\frac{4}{5}[/tex]

Answer:

When we have exponents (being multiplied) in a parenthesis which also has an exponent, the exponent of the parenthesis gets multiplied by each one of the others. We have to distribute the outer exponent to each exponent inside, like:

[tex](a^n*b^m)^p = a^{n*p}*b^{m*p}[/tex]

If there are numbers but no exponents (inside), it also happens the same, but as the exponent of the parenthesis gets multiplied by 1, we can just put the exponent, like:

[tex](a*b)^p=a^p+b^p[/tex]

So, in our case we have what we have explained: two numbers, one of them with an exponent and the other without it in a parenthesis which also has an exponent, so we multiply that exponent by the ones of the numbers inside the parenthesis.

[tex](2^3*9)^\frac{4}{5}[/tex] = [tex]2^{3*\frac{4}{5}}*9^\frac{4}{5}[/tex] = [tex]2^\frac{12}{5}*9^\frac{4}{5}[/tex]

So the answer is [tex]2^\frac{12}{5}*9^\frac{4}{5}[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = 2}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{5x - 4 = - 3x + 12}[/tex]

Move 3x to left hand side and change it's sign

⇒[tex] \sf{5x + 3x - 4 = 12}[/tex]

Move 4 to right hand side and change it's sign

⇒[tex] \sf{5x + 3x = 12 + 4}[/tex]

Collect like terms

⇒[tex] \sf{8x = 12 + 4}[/tex]

Add the numbers

⇒[tex] \sf{8x = 16}[/tex]

Divide both sides of the equation by 8

⇒[tex] \sf{ \frac{8x}{8} = \frac{16}{8} }[/tex]

Calculate

⇒[tex] \sf{x = 2}[/tex]

Answer:

C. 2.937

Step-by-step explanation:

Given the following :

H0 : p = 0.25

H1 : p > 0.25

Number of observations (n) = 647

p' = 30% = 0.3

SD = sqrt[(p(1 - p) / n)]

1 - p = 1 - 0.25 = 0.75

SD = sqrt[(0.25 * 0.75) / 647]

SD = sqrt[0.0002897]

SD = 0.0170234

Z = (p' - p) / SD

Z = (0.3 - 0.25) / 0.0170234

Z = 0.05 / 0.0170234

Z = 2.9371187 = 2.937

Answer:

D) $18,000

Step-by-step explanation:

A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by

E'(x) = 10x + 11,

where x is the number of days since the start of the job.

Find the expenditure if the job takes 5 days.

Step 1

We Integrate

E(x) =∫E'(x) dx

=∫[10(x) + 11] in hundreds of dollars

(5x² + 11x + c) in hundreds of dollars

Step 2

(5x² + 11x + c) in hundreds of dollars

x is the number of days since the start of the job.

x = 5

5x² + 11x

[5(5)² + 11(5)] in hundred of dollars

= [5 × 25 + 55] in hundreds of dollars

=[ 125 + 55] in hundreds of dollars

=[180] in hundreds of dollars

Hence the expenditure is 180 in hundreds of dollars

This means, 180 × $100

= $18000

Therefore, the expenditure costs $18,000

Answer:

Patient A receives 150 milligrams and Patient B receives 50 milligrams

Step-by-step explanation:

Patient A = 3x

Patient B = x

200 milligrams = 3x + x

200 milligrams = 4x

x = 50

Patient A = 3(50) = 150

Patient B = 50

The answer to this question can be defined as follows:

The Lower sum ="0.659"

The Upper sum ="0.859"

Step-by-step explanation:

In the given equation there is some mistype error, so the correct equation and its solution can be defined as follows:

Equation:

[tex]y= \sqrt{1-x^2}[/tex]

calculating the Δx:

[tex]=\frac{(1 - 0)}{5}\\\\=\frac{1}{5}[/tex]

calculating the Upper sum value:

[tex]=\bigtriangleup x \times (f(0) + f(\frac{1}{5}) + f(\frac{2}{5}) + f(\frac{3}{5}) + f(\frac{4}{5})) \\\\= \frac{1}{5} \times (1 + \sqrt{(\frac{24}{25})} + \sqrt{\frac{21}{25}} + \frac{4}{5} + \frac{3}{5})\\\\= 0.859[/tex]

calculating the Lower sum value:

Answer:

The upper sum value is 0.8592

The lower sum value is 0.6592.

Step-by-step explanation:

Given information:

The equation [tex]y=\sqrt{1-x^2}[/tex]

And [tex]n=5[/tex]

now, first find derivative of the above equation:

As, [tex]\Delta x=(1/5)\\\Delta x=0.2[/tex]

Now calculate the upper sum value as :

[tex]U=0.2[\sqrt{1-0}+\sqrt{1-0.2^2}+\sqrt{1-0.4^2}+\sqrt{1-0.6^2}]+ \sqrt{1-0.8^2}\\U=0.2\times 4.296\\U=0.8592\\[/tex]

Hence, the upper sum value is 0.8592

Now ,calculate the lower sum value as:

[tex]L=0.2[\sqrt{1-0.2^2}+\sqrt{1-0.4^2}+\sqrt{1-0.6^2}+\sqrt{1-0.8^2}+\sqrt{1-1^2}]\\L= 0.2\times 3.296\\L=0.6592\\[/tex]

Hence, the lower sum value is 0.6592.

Answer:

[tex]y = 7x - 175[/tex]

Step-by-step explanation:

Given

Initial temperature= 25ºC

Rise = 1ºC

Rate  = 7 joules

Required

Determine the equation of the system

Let the final temperature be represented with x and the heat required be represented with y

This question will be solved using the following heat formula

[tex]Heat\ Required = Rate * Change\ in\ Temperature[/tex]

[tex]Heat\ Required = Rate * (Final\ Temperature - Initial\ Temperature)[/tex]

Substitute y for Heat Required; 7 for Rate; x for Final Temperature and 25 for Initial Temperature

[tex]y = 7(x - 25)[/tex]

Open the bracket

[tex]y = 7x - 7 * 25[/tex]

[tex]y = 7x - 175[/tex]

Hence, the equation of the system is

Answer:

For every 72 eggs, 32 omelets can be made.

Step-by-step explanation:

The ratio for eggs to omelets is 9:4. Or 9/4 in fraction form. (Note that the ratio can be written interchangeable such as 4:9).

The ratio says for every 9 eggs, it makes 4 omelets.

72 can be multiplied by 9. (9*8=72).

If we multiply the "top" and the "bottom" of the ratio by 8/8 (8/8=1. We must multiply this way so the ratio will remain the same when reduced.)

We will get 72:32.

For every 72 eggs, 32 omelets can be made.

Answer:

We use the rule of three !

9 eggs ------------> 4 omoletes

72 eggs -----------> x

So x= (72 eggs × 4 omoletes ) / 9 eggs

We simplify by 《eggs 》 because it is in the numerator and the denominator.

So x=(72×4 omoletes) / 9

x =288 omoletes /9

x = 32 omoletes

So we can made 32 omeletes with 72 eggs !!

Answer:

y+2x = 3

Step-by-step explanation:

The formula for finding the equation of a tangent line is expressed using the point slope equation y-y0 = m(x-x0) where:

m is the slope of the line and (x0, y0) is a point on the line.

m = dy/dx = dy/dt ÷ dx/dt

dy/dt = 2(t-1)

dx/dt = e^t

m = 2(t-1)/e^t

If x = e^t, and x = 1

1 = e^t

Taking ln of both sides

ln1 = lne^t

t = ln1

t = 0

Substituting t = 0 into the slope formula:

m = 2(t-1)/e^t

m = 2(0-1)/e^0

m = 2(-1)/1

m = -2/1

m = -2

Substituting the slope m= -2 and the given point (1,1) into the formula for calculating the equation of tangent line we will have;

y-1 = -2(x-1)

y-1 = -2x+2

y+2x = 2+1

y+2x = 3

Hence the equation of the tangent line in Cartesian coordinates for the given parameter t is y+2x = 3

The surface area of the given box is 108 square inches.

The surface area of a box is the sum of the areas of its six faces. We can find the surface area of the given box by using the formula:

Surface Area = 2lw + 2lh + 2wh

where "l" is the length, "w" is the width, and "h" is the height of the box.

As per the question, we have

l = 3 inches, w = 3 inches, and h = 6 inches

Substituting the given values, we get:

Surface Area = 2(4 x 3) + 2(4 x 6) + 2(3 x 6)

Surface Area = 24 + 48 + 36

Surface Area = 108 square inches

Therefore, the surface area of the given box is 108 square inches.
