Danny charges $48 for 4 hours of swimming lessons, Martin charges $28 for 2 hours of swimming lessons. Who offers a better deal?

Answer: x = 46

Step-by-step explanation: The theorem is:

The sum of all exterior angles of a polygon is 360

Here, our polygon is a "quadrilateral" -- 4 sided figure

We can say that the sum of all 4 exterior angles is 360. We set up an equation and solve for x. Shown below:

The value of x is 46

Complete question is;

After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days. Using this as a reasonably accurate measure, find the probability that the green parrot will gross over $2200:

A. At least 5 of the next 7 business days.

B. at least 5 of the next 10 business days.

C. less than 3 of the next 5 business days.

d. Exactly 7 of the next 10 business days

e. At least 1 of the next 5 business days.

Answer:

A) P(X ≥ 5) = 0.9262

B) P(X ≥ 5) = 0.9986

C) P(X ≤ 2) = 0.0266

D) P(X = 7) = 0.1298

E) P(X ≥ 1) = 0.9999

Step-by-step explanation:

This is a binomial probability distribution problem and as such we will use the formula;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

A. At least 5 of the next 7 business days will be;

P (X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7)

P(X = 5) = C(7, 5) × 0.85^(5) × (1 - 0.85)^(7 - 5)

P(X = 5) = 0.20965

P(X = 6) = C(7, 6) × 0.85^(6) × (1 - 0.85)^(7 - 6)

P(X = 6) = 0.396

P(X = 7) = C(7, 7) × 0.85^(7) × (1 - 0.85)^(7 - 7)

P(X = 7) = 0.320577

Thus;

P(X ≥ 5) = 0.20965 + 0.396 + 0.320577

P(X ≥ 5) = 0.9262

B. Probability of at least 5 of the next 10 business days will be;

P(X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

From online binomial calculator attached, we can see that the answer is;

P(X ≥ 5) = 0.9986

C. Probability of less than 3 of the next 5 business days will be;

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

From online binomial calculator attached, we can see that the answer is;

P(X ≤ 2) = 0.0266

D. Probability of exactly 7 of the next 10 business days will be;

P(X = 7) = C(10, 7) × 0.85^(7) × (1 - 0.85)^(10 - 7)

P(X = 7) = 0.1298

e. Probability of at least 1 of the next 5 business days will be;

P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

From third image attached using online binomial calculator, we have;

P(X ≥ 1) = 0.9999

Answer:

12 pieces

Step-by-step explanation:

Total length of the board = 48 in

It must be divided into 4 pieces of equal length

This means, there will be 3 cut to have 4 pieces

Each cut will cause a waste of 3/16 in.

Total waste = 3 cut × 3/16 in

= (3*3)/16

= 9/16 in

Length of board remaining = Total length of the board - Total waste

= 48 - 9/16

= (768-9)/16

= 759/16 in

How long will each piece be after the cuts are made?

Length of each piece after the cut = Length of board remaining / 4

= 759/16 ÷ 4

= 759/16 × 1/4

= 759/64

= 11.859375

Approximately 12 pieces to the nearest whole number

Answer:

a) missing exponent is 8

b) missing exponent is -5

c) missing exponent is 15

d) missing exponent is 6

Step-by-step explanation:

for 'a' and 'b' you have to ADD the exponents

for 'c' you have to SUBTRACT the exponents

for 'd' you have to MULT the exponents

let 'n' = missing exponent

a) -5 + n = 3

    n = 8

b)  3 + n = -2

    n = -5

c) n - 6 = 9

   n = 15

d) 5n = 30

    n = 6

Step-by-step explanation:

That's my final answer

The orders are 1 stay the same. 2 change to 4, 3 change to 2, 4 change to 3, and 5 stays the same.

Multiple: 1/ 8 & 2/ 4  = 1 · 2/ 8 · 4  = 2/ 32  = 1 · 2/ 16 · 2  = 1/ 16   Multiply both numerators and denominators. Result fraction keep to lowest possible denominator (lowest=2). In the next intermediate step , cancel by a common factor of 2 gives 1/ 16 .  In words - one eighth multiplied by two quarters = one sixteenth.

Final result: 1/16

Answer: they are not

Step-by-step explanation:

y=x has a slope of 1 because the m value is 1.

x+y=-2 has a slope of -1 because when we subtract x from both sides, we get that y=-x-2 and the m value is -1

Answer:

D. 1,963 square inches

Step-by-step explanation:

Using the formula of the area of the circle A= [tex]\pi[/tex][tex]r^{2}[/tex] and assuming that the radius is 25 inches.

Then,

A = [tex]\pi[/tex](25 inches)^2

A = (3.14)(25inches)^2

A = 1,963 square inches

However, you did not state that r = 25 inches, so this might not be correct, but  good luck and I hope this helps a little!

Answer:

10.77

Step-by-step explanation:

by using Pythagoras theorem we can find the distance between the points,

so...

distance between the points, which is the hypotenuse will be xy

difference between the y coordinates will be dy

difference between the x coordinates will be dx

according to pythagoras theorem,

[tex]xy^{2} = dx^{2} + dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77[/tex]

Answer:

x = -4.604

Step-by-step explanation:

Here, we want to get the value of x

We start by dividing through by 5

e^(2x + 11) = 30/5

e^(2x + 11) = 6

Writing this in natural logarithm form, we have;

ln 6 = 2x + 11

2x + 11 = 1.792

2x = 1.792-11

2x = -9.208

x = -9.208/2

x = -4.604

The value of x from the given equation is

x=-4.604

Given :

[tex]5e^{2x+11} =30[/tex]

To solve for x , we need to get exponent 'e' alone

First we divide both sides by 5

[tex]e^{2x+11} =6[/tex]

Now we write the given exponent in logarithmic form

Lets take ln on both sides

[tex]lne^{2x+11} =ln6\\(2x+11)lne=ln(6)\\[/tex]

The value of ln(e) is 1

[tex](2x+11)=ln(6)\\2x+11=ln(6)\\subtract \; 11 \; on \; both \; sides\\2x=ln(6)-11\\Divide \; both \; sides \; by \; 2\\x=\frac{ln(6)-11}{2} \\x=-4.60412[/tex]

The value of x from the given equation is

x=-4.604

Yes. The ratios of towers to customers​ (thousands) are all equivalent to a unit rate of nothing. Therefore, option A is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent.

The given table is

Cell Phone Towers          Customers​ (thousands) Towers

        3.25                                          169

        4.25                                          221

        5.25                                          273

        7.25                                          377

Here, the ratio of Cell Phone Towers : Customers​ (thousands) Towers

3.25 : 169

= 325/16900

= (325÷325)/(16900÷325)

= 1/52

4.25 : 221

= 425/22100

= 1/52

5.25 : 273

= 525/27300

= 1/52

7.25 : 377

= 725/37700

= 1/52

Therefore, the ratio of given cell phone towers to customers​ (thousands) towers are equivalent.

Answer:

Option C : 173.8 km² is the correct answer.

Step-by-step explanation:

Given that:

Side length = 6 kilometers

A shape with 8 sides is called an octagon, therefore, the given figure is an octagon.

Area of octagon is given by;

Area = [tex]2(1+\sqrt{2})a^2[/tex]

Putting a=6

Area = [tex]2(1+\sqrt{2})(6)^2[/tex]

Area = [tex](2+2\sqrt{2})(36)[/tex]

Area = 173.82

Rounding off to one decimal place

Area = 173.8 km²

Hence,

Option C : 173.8 km² is the correct answer.
