Answer:

Step-by-step explanation:

The answer is 105 units²

Explanation:

Since the middle is a square, the base of all 4 triangles are equal.

Let x be the height of the triangles.

The height of the triangle can be defined as:

15 = 7 + x + x

15 = 7 + 2x

15 - 7 = 2x

x = 8/2

x = 4

Area = area of square + 4(area of triangle)

= (7 x 7) + 4(1/2(7)(4))

= 49 + 56

= 105 units²

On the first line the distributive property was used. This property says that the product of a constant with a sum of two numbers is equal to the sum of the products.

On the third line the "associative" property was used. This property says that if you have the sum of three numbers the order at which you sum them doesn't affect the results.

According to the pigeonhole principle, if there are more pigeons than there are pigeonholes, then at least one pigeonhole must hold more than one pigeon.

Answer:

He gave you 48 cards.

Step-by-step explanation:

150 * 32% (which is also 0.32) is equal to 48.

Divide the percentage by 100.

32 / 100 = 0.32.

You then multiply 0.32 by 150 to get the part.

0.32 x 150 = 48.

32% of 150 is 48.

Your answer is 48 cards.

Let the probability mass function of the number of draws before some ball is chosen more than once be given by the function p(m;n).

SolutionFirst, let's consider the base case: $n = 2$Then the probability mass function is:p(1;2) = 0 (obviously)p(2;2) = 1 (after the second draw, the ball chosen must be the same as the first one)Now consider $n = 3$. We have two possibilities:either the ball drawn the second time is the same as the first one, which can be done in $1$ way, with probability $\frac{1}{3}$,or it isn't, in which case we need to draw a third ball, which must be the same as one of the first two.

This can be done in $2$ ways, with probability $\frac{2}{3} \cdot \frac{2}{3} = \frac{4}{9}$.Therefore:p(1;3) = 0p(2;3) = $\frac{1}{3}$p(3;3) = $\frac{4}{9}$Now we will prove that:p(m; n) = $\frac{n!}{n^{m}}{m-1\choose n-1}$.The proof uses the following counting argument. Suppose you have $m$ balls and $n$ labeled bins. The number of ways to throw the balls into the bins such that no bin is empty is ${m-1\choose n-1}$, and there are $n^{m}$ total ways to throw the balls into the bins.

Therefore the probability that you can throw $m$ balls into $n$ bins without leaving any empty bins is ${m-1\choose n-1}\frac{1}{n^{m-1}}$.For $m-1$ draws, we need to choose $n-1$ balls from $n$ balls, and then we need to choose which of these $n-1$ balls appears first (the remaining ball will necessarily appear second).

Hence the probability mass function is:$p(m; n) = \begin{cases} 0 & m \leq 1 \\ {n-1\choose n-1}\frac{1}{n^{m-1}} & m = 2 \\ {n-1\choose n-1}\frac{1}{n^{m-1}} + {n-1\choose n-2}\frac{n-1}{n^{m-1}} & m \geq 3 \end{cases}$We can simplify this by using the identity ${n-1\choose k-1} + {n-1\choose k} = {n\choose k}$. So we have:$p(m; n) = \begin{cases} 0 & m \leq 1 \\ {n\choose n}\frac{1}{n^{m-1}} & m = 2 \\ {n\choose n}\frac{1}{n^{m-1}} + {n\choose n-1}\frac{1}{n^{m-2}} & m \geq 3 \end{cases}$As required.

Answer:

(12) The perimeter of the four shaped figure is 12x - 10

(13) The perimeter of the rectangle is 18x + 10

(14) The perimeter of the hexagon is 24x

Step-by-step explanation:

(12) The perimeter of the four shaped figure is calculated as;

P = (x )  +   (3x + 2)    +  (6x - 17)   +  (2x + 5)

Collect like terms together, in order to simplify the expression

P = (x + 3x + 6x + 2x) + (2 - 17 + 5)

P = 12x - 10

(13) The perimeter of the rectangle is calculated as;

P = 2( L + B)

P = 2L + 2B

Where;

L is length of the rectangle

B is the breadth of the rectangle

P = 2 (6x + 5) + 2(3x)

P = 12x + 10  + 6x

P = 18x + 10

(14) The perimeter of the hexagon is calculated as;

P = 6L

Where;

L is length of each side

P = 6 (4x)

P = 24x

The amount of americium-241 consumed in a smoke detector, initially containing 4.50 µg, after one year can be calculated to be approximately 0.0104 µg.

The decay of americium-241 over time can be modeled using the radioactive decay formula:

A(t) = A₀ * (1/2)^(t / T₁/₂)

where:

A(t) is the amount of americium-241 remaining after time t,

A₀ is the initial amount of americium-241,

t is the time elapsed,

T₁/₂ is the half-life of americium-241.

In this case, the initial amount of americium-241 is 4.50 µg, and the half-life is 433 years. We want to calculate the amount remaining after one year.

Substituting the given values into the decay formula:

A(1 year) = 4.50 µg * (1/2)^(1 / 433)

Calculating this expression:

A(1 year) ≈ 4.50 µg * 0.998005

A(1 year) ≈ 4.492 µg

Therefore, the amount of americium-241 consumed in the smoke detector after one year is approximately 4.50 µg - 4.492 µg ≈ 0.0104 µg.

After one year, approximately 0.0104 µg of americium-241 would be consumed in a smoke detector initially containing 4.50 µg of americium-241, considering its half-life of 433 years.

Answer:

a) (x – 3\7) = 2\3 (3\2x – 9\14 )

c) 12.3x – 18 = 3(–6 + 4.1x)

Step-by-step explanation:

A linear equation can be said to have an infinite number of solutions when the number of the right hand side is the same at the number on the left hand side of the equation.

For example:

2 = 2 or x = x or 0 = 0

Solving the question above:

Which linear equations have an infinite number of solutions? Check all that apply.

a) (x – 3\7) = 2\3 (3\2x – 9\14 )

x - 3/7 = 6x/6 - 18/42

x - 3/7 = x - 3/7

Collect like terms

x - x = -3/7 + 3/7

0 = 0

The linear equation in option a has an infinite number of solutions

b) 8(x + 2) = 5x – 14

8x + 16 = 5x - 14

Collect like terms

8x - 5x = -14 - 16

3x = -30

x = -30/3

x = -10.

The linear equation in Option b has a true solution.

c) 12.3x – 18 = 3(–6 + 4.1x)

12.3x - 18 = -18 + 12.3x

Collect like terms

12.3x - 12.3x = -18 + 18

0 = 0

The linear equation in Option c has infinite number of solutions

d) 1\2(6x + 10) = 7(3\7x – 2)

6x/2 + 5 = 21/7x - 14

3x + 5 = 3x - 14

Collect like terms

3x - 3x = -14 - 5

0 = -19

The linear equation Option d has no solution

e) 4.2x – 3.5 = 2.1 (5x + 8)

4.2x - 3.5 = 10.5x + 16.8

Collect like terms

4.2x - 10.5x = 16.8 + 3.5

-6.3x = 20.3

x = -20.3/6.3

x = -3.22

Hence, the linear equation in Option e has a true solution

Therefore, the linear equations have an infinite number of solutions are:

a) (x – 3\7) = 2\3 (3\2x – 9\14 )

c) 12.3x – 18 = 3(–6 + 4.1x)

Step-by-step explanation:

a) The 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).

b) The 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).

To calculate the confidence intervals for the population proportion, we can use the formula:

Confidence Interval = sample proportion ± margin of error

The margin of error can be calculated using the formula:

Margin of Error = critical value * standard error

where the critical value is determined based on the desired confidence level and the standard error is calculated as:

Standard Error = \(\sqrt{((p * (1 - p)) / n)}\)

Given that the sample proportion (p) is 0.81 and the sample size (n) is 500, we can calculate the confidence intervals.

a. 90% Confidence Interval:

To find the critical value for a 90% confidence interval, we need to determine the z-score associated with the desired confidence level. The z-score can be found using a standard normal distribution table or calculator. For a 90% confidence level, the critical value is approximately 1.645.

Margin of Error = \(1.645 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)

≈ 0.0323

Confidence Interval = 0.81 ± 0.0323

≈ (0.7777, 0.8423)

Therefore, the 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).

b. 95% Confidence Interval:

For a 95% confidence level, the critical value is approximately 1.96.

Margin of Error = \(1.96 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)

≈ 0.0363

Confidence Interval = 0.81 ± 0.0363

≈ (0.7737, 0.8463)

Thus, the 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).
