Answer:

  (x +8)^2 +(y +1)^2 = 16

Step-by-step explanation:

The standard form equation for a circle with center (h, k) and radius r is ...

  (x -h)^2 + (y -k)^2 = r^2

For your center and radius, the equation is ...

  (x -(-8))^2 +(y -(-1))^2 = 4^2

  (x +8)^2 +(y +1)^2 = 16

Answer:

The taxi driver's average profit per trip is 4.4.

Step-by-step explanation:

Probability of fares picked up in zone A with destinations in zone A = 0.6

Probability of fares picked up in zone A with destinations in zone B = 0.4

Probability of fares picked up in zone B with destinations in zone A = 0.3

Probability of fares picked up in zone B with destinations in zone B = 0.7

The driver's expected profit for a trip entirely in zone A = 6

The driver's expected profit for a trip entirely in zone B = 8

The driver's expected profit for a trip involving both zones is 12

The taxi driver's average profit per trip:

zone A with destinations in zone A = 0.6 * 6 =  3.6

zone A with destinations in zone B = 0.4 * 12 = 4.8

zone B with destinations in zone A = 0.3 * 12 = 3.6

zone B with destinations in zone B = 0.7 * 8 =  5.6

Total profit expected for 4 trips =                     17.6

Average profit per trip = 4.4 (17.6/4)

Answer:

12.57

Step-by-step explanation:

A = πr^2

3.14 x 2 x 2 = 12.57 meters ^2

ANSWER: approximately 18.84 meters  

Step-by-step explanation:

The most commonly used equation for circumference is C=2πr.  Where c is the circumference, π is pi (or 3.14159...), and r is the radius.

In your equation, you are given diameter.  Remember that the radius is half of the diameter.  So, in this case, the radius, r, is half of 6, or 3 meters.

Now, substitute the radius into the equation for circumference, and you get:

C= 2π(3)

=approximately 18.84 meters

What you know have found is the distance around the circle.

Answer:

120 times

Step-by-step explanation:

There are 5 people to fill the first place, 4 remaining to fill the second, 3 remaining to fill the third, 2 remaining to the fourth place and only 1 remaining to fill the fifth. That means there are 5 factorial (5!) ways. 5! = 5 x 4 x 3 x 2 x 1 = 120.

Correct question is;

A. p(-1.80 < z < 0.20 )

B. p(-0.4 < z < 1.4)

C. p(0.25 < z < 1.25)

D. p(-0.9 < z < -0.6)

Answer:

A) p(-1.80 < z < 0.20) = 0.54333

B) p(-0.4 < z < 1.4) = 0.57466

C) p(0.25 < z < 1.25) = 0.29564

D) p(-0.9 < z < -0.6) = 0.90981

Step-by-step explanation:

A) p(-1.80 < z < 0.20 )

This gives us;

P(z < 0.2) - P(z < -1.8)

From z-distribution tables;

P(z > 0.2) = 0.57926

And P(z < -1.8) = 0.03593

Thus;

p(-1.80 < z < 0.20) = 0.57926 - 0.03593 p(-1.80 < z < 0.20) = 0.54333

B) p(-0.4 < z < 1.4)

This gives us;

P(z < 1.4) - P(z < -0.4)

From z-distribution table, we have;

P(z > 1.4) = 0.91924

P(z < -0.4) = 0.34458

Thus;

p(-0.4 < z < 1.4) = 0.91924 - 0.34458

p(-0.4 < z < 1.4) = 0.57466

C) p(0.25 < z < 1.25)

From z-distribution table, we have;

P(z < 0.25) = 0.59871

P(z > 1.25) = 0.10565

Now, to solve this;

p(0.25 < z < 1.25) = 1 - (P(z < 0.25) + P(z > 1.25))

This gives;

p(0.25 < z < 1.25) = 1 - (0.59871 + 0.10565)

p(0.25 < z < 1.25) = 0.29564

D) p(-0.9 < z < -0.6)

From z-distribution table, we have;

P(z < -0.9) = 0.18406

P(z > -0.6) = 0.72575

Thus;

p(-0.9 < z < -0.6) = 0.18406 + 0.72575

p(-0.9 < z < -0.6) = 0.90981

Answer:

10 years

Step-by-step explanation:

let age of the boy x , and let age of his dad y

x - y = 26

y + 3 = (x+3) / 3

x - 26 = (x+3) / 3

3x - 69 = x + 3

2x = 72

x = 26, y = 10

Answer:

Step-by-step explanation:

It looks like every time the coefficient increases by 3 while the exponent increases by 1.

[tex]\\45\\\sum 3(n+1)x^{n}\\n = 0[/tex]

Notice it starts at zero so 3 is multiplied by (x+1) to make it start from 0

The exponent is simply n, because at the start is it zero [tex]x^0=1[/tex], then 1, then 2, so on.

The upper limit is 45 because 45 - 0 = 45 terms

This student's GPA is 3.04.

Step-by-step explanation:

Student's GPA:

To find the students GPA, we find the sum of the multiplication of each numerical grade(A is 4, A- is 3.67 and so on) and the credit load of the course, divided by the number of courses.

His grades are:

4 in English worth 3 credits.

4 in Antropology worth 3 credits.

2.67 in Chemistry worth 4 credits.

2 in French worth 4 credits.

3 in Theatre worth 2 credits.

GPA:

[tex]\frac{4*3+4*3+2.67*4+2*4+3*2}{3+3+4+4+2} = 3.04[/tex]

This student's GPA is 3.04.

Answer:

11.09units

Step-by-step explanation:

Find the diagram attached

The radius of the circle is line projecting from the center to the circumference. Hence AB is the radius of the circle.

To get AB, we will use the pythagoras theorem as shown;

Given

AC=22

BC=19

AC² = AB²+BC²

22² = AB²+19²

AB² = 22²-19²

AB² = 484-361

AB² = 123

AB = √123

AB = 11.09

Hence the radius of the circle is 11.09units

Answer:

Step-by-step explanation:

radius = 3mm

diameter = 6mm

circumference = 6 x 3,14 = 18.84 mm

area = 3^2 x 3,14 = 28.26 mm^2

Answer:

40 students in each bus.

Step-by-step explanation:

Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.

248-8=240

240/6=40

40 students in each bus.

a^2 + b^2 = c^2

Let c = hypotenuse = 2x

One of the legs = x. Let a or b = x.

I will let a = x. We can then say that b = 3.

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

9 + x^2 = 4x^2

9 = 4x^2 - x^2

9 = 2x^2

9/2 = x^2

sqrt{9/2} = sqrt{x^2}

3/sqrt{2} = x

Rational denominator.

[3•sqrt{2}]/2 = x = a

Side 3 is given to be 3 feet. So, b = 3.

Hypotenuse = 2x

Hypotenuse = 2([3•sqrt{2}]/2)

Hypotenuse = 3•sqrt{2}

Understand?

The three sides are 3, [3•sqrt{2}]/2 and

3•sqrt{2}.

Answer:

Constant monomial

Step-by-step explanation:

Monomial means that there is only one term, so constant trinomial cannot be correct.

Quintic monomials have a degree of 5 and quadratic monomials have a degree of 4, but this has a degree of zero, so this must be a constant monomial.

I hope this helps you. Have a nice day.
