Answer:

Yes.  There can be 56 games (92%) of Exploding Snap every evening throughout September and October that can be played without having the same three Gry ndors play a game twice.

Step-by-step explanation:

This is a combination game without repetition.

The formula for combination without repetition is:

n! /r! (n - r)!

where n = 8 and r = 3

Therefore, n! /r! (n - r)!

= 8! / 3! (8 -3)!

= 40,320 / 6 (120)

= 40,320 / 720

= 56

There are 30 nights in September and 31 nights in October, totaling 61 nights

This implies that 56/61 games can be played in these two months without repeating the same three gamers.

56/61 = 0.918

= 92%

Answer:

I cant tell what u mean but if the angles are equal the answer is 10

Step-by-step explanation:

Based on the calculations, the value of x is equal to 42.5.

Given the following data:

To determine the value of x:

A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.

Mathematically, a supplementary angle is calculated as follows:

[tex]Angle\;2+Angle\;4 =180\\\\3x-5 +x+15=180\\\\4x+10=180\\\\4x=180-10\\\\4x=170\\\\x=\frac{170}{4}[/tex]

x = 42.5.

Answer:

265.1

Step-by-step explanation:

10% = 0.1

15% = 0.15

0.1(42)(8) + 0.15(14)(15) + 200 = 33.6 + 31.5 + 200 = 265.1 - total amount  Adam earned last week.

The drawing should have a scale of 400:1.

A scale is a group of levels or numbers that are applied to a certain system of measurement or comparison.

Given, the drawing length is 7cm and the real length is 28 meters.

real length in cm = 2800. hence,

Scale of drawing = 2800: 7 = 400 : 7

Therefore, 400: 1 would be the scale of the given drawing.

Answer:

the smallest number of equally sized pieces is 20

Step-by-step explanation:

The computation of the smallest number of equally sized pieces is as follows:

Given that

The sum of 1 by 5 and 3/4

Now

if we sum it

= 1 ÷ 5 + 3 ÷ 4

= 4 + 15 ÷ 20

= 19 ÷ 20

Now as if we do the lcm so the denominator sum be 20

Therefore the smallest number of equally sized pieces is 20

Answer:

2%

Step-by-step explanation:

so the point [tex](\sqrt{3},\sqrt{7})[/tex] is in the circumference so the distance from (0,0) to this point will be the radius of the bullseye

[tex]x=\sqrt{(\sqrt{3}-0)^2+(\sqrt{7}-0)^2}\\\\x=\sqrt{3+7}\\\\x=\sqrt{10}[/tex]

so that's the radius

so the area will be

[tex]A=\pi x^2\\\\A=\pi (\sqrt{10})^2\\\\A=10\pi[/tex]

so the percentage is

[tex]P=\frac{A}{1600}\\\\=\frac{10\pi}{1600}\\\\=\frac{\pi}{160}\\\\P\approx 0.02[/tex]

so it's 2%

Given:

Decay rate: 1.5% per year = -0.015

To find:

The half life.

Solution:

The continuous exponential decay function is

[tex]A(t)=Ae^{-kt}[/tex]

where, a is initial value, -k is decay rate and t is time period.

For half life, [tex]A(t)=\dfrac{A}{2}[/tex],

[tex]\dfrac{A}{2}=Ae^{-0.015t}[/tex]

Dividing both sides by A.

[tex]\dfrac{1}{2}=e^{-0.015t}[/tex]

Taking natural log on both sides.

[tex]\ln \dfrac{1}{2}=\ln e^{-0.015t}[/tex]

[tex]-0.69314718=-0.015t[/tex]

Divide both sides by -0.015.

[tex]\dfrac{-0.69314718}{-0.015}=t[/tex]

[tex]46.209812 =t[/tex]

[tex]t\approx 46[/tex]

Therefore, the half life is 46 years.

A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)

B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)

C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)

Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).

Answer:

The answers to the questions are well numbered below.

Step-by-step explanation:

We have arrival rate

λ = 7 in every 10 minutes = 0.7

Service time u = 7 minutes

1. Average time a car is in system

W = 1/u - λ

= 1/7-0.7

= 0.1587

= 0.16 to 2 decimal places

2. Average number of cars in system

= λ/u-λ

= 0.7/7-0.7

= 0.1111

= 0.11 to 2 decimal places

3. Average time that cars spend to receive service

= λ/u(u-λ)

= 0.7/7(7-0.7)

= 0.01587

= 0.016 to 2 decimal places

4. Average number of cars in line behind customer receiving service

= λ²/u(u-λ)

= 0.7²/7(7-0.7)

= 0.49/44.1

= 0.011 to 2 decimal places

5. Probability no cats at window

1-λ/u

= 1-0.7/7

= 0.9 = 9%

6. Percentage of time postal clerk is busy

= λ/u = 0.7/7 = 0.1 = 10%

7. Probability of exactly 2 cars

= λ²e^-λ/2!

= 0.7²e^-0.7/2!

= 0.1217

= 12.17%

Step-by-step explanation:

Since the leading degree of the resulting expression is 2, hence the  polynomial simplifies to an expression that is a quadratic

Polynomial expressions are expressions that has a leading degree of 3 and above.

Given the expression

(-5x² - 2x + 4) + (8x² - x - 1) - (x+2)(x-5)

Expand the polynomial

(-5x² - 2x + 4) + (8x² - x - 1) - (x² -3x - 10)

Collect the like terms

-5x² + 8x² - x² - 2x - x + 3x + 4 - 1 + 10

2x²  + 13
