The following is a list of 5 measurements. 19,30,20,10,17 Suppose that these 5 measurements are respectively labeled.

Answer:

YES

Step-by-step explanation:

$157+$210+$377+$145=$889

$695+$95=$790

Leftover

$889-$790 =$99

he would have $99 leftover

The amount left over with Jean is given by the equation A = $ 99

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount left over be represented as A

Now , the equation will be

The cost of basic computer is = $ 695.00

The cost of printer is = $ 95.00

The amount saved in month of May = $ 157.00

The amount saved in month of June = $ 210.00

The amount saved in month of July = $ 377.00

The amount saved in month of August = $ 145.00

The total amount saved = $ 157.00 + $ 210.00 + $ 377.00 + $ 145.00

The total amount saved = $ 889

The total cost of computer and printer = $ 695 + $ 95

The total cost of computer and printer = $ 790

The amount of money left over with Jean A = total amount saved - total cost of computer and printer

Substituting the values in the equation , we get

The amount of money left over with Jean A = $ 889 - $ 790

The amount of money left over with Jean A = $ 99

Therefore , the value of A is $ 99

Hence , the amount left over is $ 99

To find the area of the arena, you will need to find the areas of the rectangular spaces and the 2 semicircles. Because the formulas are given, I will just substitute in the values and show the work for finding the areas.

To find the perimeter, you will look at the distances of lines that take you around the space. Because two of these spaces are half circles, you will need to find the circumference of the full circle.

Also, the answers need to be given in meters, so all units given in centimeters will be divided by 100 to convert them to meters.

Perimeter:

C= 3.14 x 20 m

C = 62.8 meters

62.8 + 8 + 25 + 8 + 5 + 8 + 10 + 8 + 40= 174.8 meters for the Perimeter

Area:

A = 25 x 8

A = 200 square meters

A = 10 x 8

A = 80 square meters

A = 20 x 40

A = 800 square meters

A = 3.14 x 10^2

A = 314 square meters

Total Area: 314 + 800 + 80 + 200= 1394 square meters

Correct answer choice: C. -2

Answer:

c is the square of half of b

Step-by-step explanation:

A quadratic equation can be written in the following form:

[tex]ax^2+bx+c[/tex].

Based off of the information provided, we can test to see if which answer choice is correct.

OPTION A IS INCORRECT:

Although, for [tex]x^2+6x+9[/tex], c is 1.5 times b, we do not see that relationship reflected in other equations, such as [tex]x^2+10x+25[/tex] and [tex]x^2+12x+36[/tex].  There must be a different relationship.

OPTION B IS INCORRECT:

Although c is double b for x^2+8x+16, this rule is not applicable for the rest of the equations. C is double b for the  is 1.5 times that of b for x^2+6x+9, and for and for x^2+10x+25, c is 2.5 times b, and for x^2+12x+36, c is 3 times of b.

OPTION C IS CORRECT:

We can test this relationship based off of the information given.

for x^2+6x+9, c equals (6/2)^2 which is 9

for x^2+8x+16, c equals (8/2)^2 which is 16

for x^2+10x+25 c equals (10/2)^2 which is 25

and finally, for x^2+12x+36 c equals (12/2)^2 which is 36.

OPTION D IS INCORRECT:

C is not the square of B.

for x^2+6x+9, b^2 which is 36 (c here is 9)

for x^2+8x+16, b^2 is 64 (c here is 16)

for x^2+10x+25 b^2 is 100 (c here is 25)

Answer: (0,0)

Step-by-step explanation:

When x is 0  then input 0 into the equation for x and solve for y.

y = -3(0)

y = 0

So x is 0 and y will also be zero so we will have the ordered pair (0,0)

Answer:

The ordered pair is (0,0)

Step-by-step explanation:

y=-3x

Let x = 0

y = -3*0

y = 0

The ordered pair is (0,0)

(a) Recall that

[tex]\dfrac{\mathrm d[\sin^{-1}x]}{\mathrm dx}=\dfrac1{\sqrt{1-x^2}}[/tex]

[tex]\dfrac{\mathrm d[\ln x]}{\mathrm dx}=\dfrac1x[/tex]

[tex]\dfrac{\mathrm d[\sqrt x]}{\mathrm dx}=\dfrac1{2\sqrt x}[/tex]

Then by the chain rule,

[tex]y=\sin^{-1}(\sqrt x)+\ln(\sqrt x)[/tex]

[tex]\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm d[\sin^{-1}(\sqrt x)+\ln(\sqrt x)]}{\mathrm dx}[/tex]

[tex]=\dfrac1{\sqrt{1-(\sqrt x)^2}}\dfrac{\mathrm d[\sqrt x]}{\mathrm dx}+\dfrac1{\sqrt x}\dfrac{\mathrm d[\sqrt x]}{\mathrm dx}[/tex]

[tex]=\dfrac1{2\sqrt x\sqrt{1-x}}+\dfrac1{2(\sqrt x)^2}[/tex]

[tex]=\dfrac1{2\sqrt{x-x^2}}+\dfrac1{2x}[/tex]

[tex]=\boxed{\dfrac{x+\sqrt{x-x^2}}{2x\sqrt{x-x^2}}}[/tex]

(b) I'll assume [tex]\log x[/tex] refers to the logarithm of base [tex]e[/tex]. Recall that

[tex]\dfrac{\mathrm d[e^x]}{\mathrm dx}=e^x[/tex]

[tex]2^x=e^{\log2\,x}\implies\dfrac{\mathrm d[2^x]}{\mathrm dx}=e^{\log2\,x}\dfrac{\mathrm d[\log2\,x]}{\mathrm dx}=\log2\cdot2^x[/tex]

Then using the chain rule and implicit differentiation, we get

[tex]e^y=2^x\log x-e^{2x}[/tex]

[tex]\implies e^y\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm d[2^x]}{\mathrm dx}\log x+2^x\dfrac{\mathrm d[\log x]}{\mathrm dx}-e^{2x}\dfrac{\mathrm d[2x]}{\mathrm dx}[/tex]

[tex]e^y\dfrac{\mathrm dy}{\mathrm dx}=\log2\cdot2^x\log x+\dfrac{2^x}x-2e^{2x}[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\log2\cdot2^x\log x+\frac{2^x}x-2e^{2x}}{e^y}[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\log2\cdot2^x\log x+\frac{2^x}x-2e^{2x}}{2^x\log x-e^{2x}}[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\boxed{\dfrac{\log2\cdot2^xx\log x+2^x-2xe^{2x}}{x(2^x\log x-e^{2x})}}[/tex]

If instead [tex]\log x=\log_{10}x[/tex] denotes the base 10 logarithm, you need only make the following adjustment:

[tex]\log x=\dfrac{\ln x}{\ln 10}\implies\dfrac{\mathrm d[\log_{10}x]}{\mathrm dx}=\dfrac1{\ln10\,x}[/tex]

where [tex]\ln x[/tex] is logarithm of base [tex]e[/tex].

Question:

Based on a survey, assume that 28% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly three of them are comfortable with delivery by drones.

Identify the values of n, x, p, and q.

Answer:

[tex]n = 5[/tex]

[tex]x = 3[/tex]

[tex]p = 0.28[/tex]

[tex]q = 0.72[/tex]

Step-by-step explanation:

Given

Proportion of customers that prefer drone = 28%

Selected customers= 5

Customers expected to prefer drone = 3

Required

Determine the value of n, x, p and q

In probability; n represents the selected sample;

So;

[tex]n = 5[/tex]

The expected number of people to prefer drone is represented by x;

So;

[tex]x = 3[/tex]

In probability, opposite probabilities add up to 1

i.e.

[tex]p + q = 1[/tex]

Where p is the given probability;

[tex]p = 28\%[/tex]

Convert to decimal

[tex]p = 0.28[/tex]

Substitute 0,28 for p in the above equation

[tex]p + q = 1[/tex] becomes

[tex]0.28 + q = 1[/tex]

Make q the subject of formula

[tex]q = 1 - 0.28[/tex]

[tex]q = 0.72[/tex]

(a) For each value of X we have:

[tex]X=0\quad\Rightarrow\quad Y=4\\\\X=1\quad\Rightarrow\quad Y=-23\\\\X=2\quad\Rightarrow\quad Y=-32\\\\X=3\quad\Rightarrow\quad Y=-23\\\\X=4\quad\Rightarrow\quad Y=4\\\\X=5\quad\Rightarrow\quad Y=49[/tex]

so the range of Y = {-32, -23, 4, 49}

(b)

[tex]P\{Y=4\}=P\{X=0\}+P\{X=4\}=0.00032+0.4096=\boxed{0.40992}[/tex]

(c)

Y cannot equal 0, so

[tex]P\{Y=0\}=0[/tex]

Answer:

$65.04

Step-by-step explanation:

Given:

Total amount left by the customer on table = $80

It contains cost of the food + 15% tip + 8% sales tax.

Sales tax and tip are calculated from the cost of food.

To find:

Cost of the food = ?

Solution:

Let the cost of food = $[tex]x[/tex]

As per given question statement:

Tip = 15% of [tex]x[/tex]

Sales Tax = 8% of [tex]x[/tex]

Money left on table = Cost of food + Tip + Sales tax

$80 = [tex]x[/tex] + 15% of [tex]x[/tex] + 8% of [tex]x[/tex]

Now, let us solve the equation:

[tex]\$80 = x + 15\%\ of\ x + 8\%\ of\ x\\\Rightarrow 80 = x + \dfrac{15}{100} \times x + \dfrac{8}{100} \times x\\\Rightarrow 80 = \dfrac{100x + 15\times x + 8\times x}{100}\\\Rightarrow 80 = \dfrac{123x}{100}\\\Rightarrow 80 \times 100= 123x\\\Rightarrow x = \dfrac{8000}{123}\\\Rightarrow \bold{x = \$65.04}[/tex]

Therefore, the cost of food, rounded off to nearest cent is $65.04.

Answer:

Step-by-step explanation:

The cost of the food as x, the tips as 0.15, and the tax as 0.08x. Then setting up and solving the equation x+0.15x+0.08x=80.

Answer:

Step-by-step explanation:

We are to prove the cofunction Identity using the Addition and Subtraction Formulas. [tex]tan(\pi/2 - u) = cot (u)[/tex]

From trigonometry identity, [tex]tan x = sinx/cosx[/tex], starting from right hand side of the equation, the expression above will become;

[tex]tan(\pi/2 - u) = \dfrac{sin(\frac{\pi}{2}-u )}{cos(\frac{\pi}{2}-u) }........ \ 1 \\\\from\ quadrant;\\\\sin(\frac{\pi}{2}-u) = cos (u) \ and \ cos(\frac{\pi}{2}-u) = sin(u)[/tex]

Substituting this trigonometry identities into equation 1 we will have;

[tex]tan(\pi/2 - u) = \dfrac{cos(u)}{sin(u)}[/tex]

Since cot(u) = 1/tan(u) = cos(u)/sin(u), hence;

[tex]tan(\pi/2 - u) = \dfrac{cos(u)}{sin(u)} = cot(u)\\\\tan(\pi/2 - u) = cot (u)\ Proved![/tex]
