Whose card Length Width Perimeter Area

Sanya          10 cm 8cm               36cm         80 cm²

The perimeter of a shape is the distance around its edges. For a rectangle, like Sanya's greeting card, the perimeter can be found by adding up the lengths of all four sides. In this case, we have:

Perimeter = 2 × Length + 2 × Width

Perimeter = 2 × 10 cm + 2 × 8 cm

Perimeter = 20 cm + 16 cm

Perimeter = 36 cm

So, the perimeter of Sanya's greeting card is 36 centimeters. This means that if you were to walk all the way around the edges of the card, you would cover a distance of 36 centimeters.

The area of a shape is the amount of space it takes up. For a rectangle, the area can be found by multiplying its length by its width. In this case, we have:

Area = Length × Width

Area = 10 cm × 8 cm

Area = 80 cm²

So, the area of Sanya's greeting card is 80 square centimeters. This means that if you were to cover the card completely with paint or ink, you would need 80 square centimeters of paint or ink.

a) The graphic that illustrates the shape of the distribution of the data is shown below:



b) The Central Limit Theorem states that the distribution of sample means will be approximately normal with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size. In this case, the sample mean is 56.4645 and the sample standard deviation is 14.6052. Therefore, the standard deviation of the sample mean is 14.6052/sqrt(11) = 4.4016. Using a z-score of 1.645 for a 90% confidence interval, the interval is (56.4645 - (1.645*4.4016), 56.4645 + (1.645*4.4016)) = (50.2155, 62.7135). One reservation about this estimate is that the sample size is small and the distribution of the data is not normal, so the Central Limit Theorem may not be accurate.

c) The empirical bootstrap distribution (EBD) for the mean using 200 resamples is shown below:



The shape of the EBD is approximately normal, which is expected according to the Central Limit Theorem.

d) The 90% bootstrap confidence interval for the mean can be found by taking the 5th and 95th percentiles of the EBD. The 5th percentile is 52.7455 and the 95th percentile is 60.4818, so the interval is (52.7455, 60.4818). This interval is slightly wider than the one in (b), which is expected because the bootstrap method takes into account the variability of the sample.

e) The empirical bootstrap distribution (EBD) for the median using 200 resamples is shown below:



The EBD for the median is not as smooth as the EBD for the mean, and there are several spikes in the distribution. This occurs because the median is a more discrete measure than the mean, so there are fewer possible values for the median in the resamples.

The expected net gain (or loss) for playing one game is -$3.125, which rounds to -$3.25. The correct answer is d. -$3.25.

I am a question answering bot and do not have personal experiences to share. However, I can help you find the expected net gain (or loss) for playing one game in this scenario.

First, let's calculate the probability of each possible outcome:
- Probability of winning: 1/8
- Probability of placing 2nd or 3rd: 2/8
- Probability of placing 4th through 8th: 5/8

Next, let's calculate the net gain (or loss) for each possible outcome:
- Net gain for winning: $125 - $25 = $100
- Net gain for placing 2nd or 3rd: $0 (since you receive your money back)
- Net gain for placing 4th through 8th: -$25 (since you lose your money)

Finally, let's use these probabilities and net gains to calculate the expected net gain (or loss) for playing one game:
Expected net gain = (Probability of winning) x (Net gain for winning) + (Probability of placing 2nd or 3rd) x (Net gain for placing 2nd or 3rd) + (Probability of placing 4th through 8th) x (Net gain for placing 4th through 8th)
= (1/8) x ($100) + (2/8) x ($0) + (5/8) x (-$25)
= $12.50 + $0 - $15.625
= -$3.125

Therefore, the expected net gain (or loss) for playing one game is -$3.125, which rounds to -$3.25. The correct answer is d. -$3.25.

The solution of the given system is x = -5/2, y = 2, and z = 13/2.

To determine whether the given system is inconsistent, dependent, or neither, we need to solve the system using any of the methods, such as substitution or elimination.

The given system is:
4x + y + 4z = 4
5x - y + 3z = 5
x - 2y - z = 0

Let's use the elimination method to solve the system.

Multiply the first equation by 2 and subtract the second equation from it to eliminate the y variable.
8x + 2y + 8z = 8
5x - y + 3z = 5
-------------------
3x + 5z = 3

Multiply the third equation by 2 and subtract it from the second equation to eliminate the y variable.
5x - y + 3z = 5
2x - 4y - 2z = 0
-------------------
3x + y + 5z = 5

Subtract the equation obtained in step 1 from the equation obtained in step 2 to eliminate the x variable.
3x + y + 5z = 5
3x + 5z = 3
----------------
y = 2

Substitute the value of y in the third equation to find the value of z.
x - 2(2) - z = 0
x - 4 - z = 0
x + z = 4

Substitute the value of y in the second equation to find the value of x.
5x - (2) + 3z = 5
5x + 3z = 7

Substitute the value of x + z in the equation obtained in step 5.
5(4 - z) + 3z = 7
20 - 5z + 3z = 7
2z = 13
z = 13/2

Substitute the value of z in the equation obtained in step 4 to find the value of x.
x + (13/2) = 4
x = 4 - (13/2)
x = -5/2

Therefore, the solution of the given system is x = -5/2, y = 2, and z = 13/2. Since the system has a unique solution, it is neither inconsistent nor dependent. Hence, the given system is neither inconsistent, dependent, nor neither.

Answer: 52.5

Step-by-step explanation: I used a calculator.

The polygon with an interior angle

sum of 1080° is an octagon, or

polygon with 8 sides.

We are given that the interior angle

sum of our polygon is 1080°. We also

know that the sum of the interior

angle of any polygon with "n" sides is

given by the formula (n - 2) × 180°.

Therefore, to determine the number

of sides that our polygon has, we set

this formula equal to 1080°, and solve

for "n".

Divide both sides of the equation by

180°.

Add 2 to both sides of the equation.

We get that our polygon has 8 sides,

and the name of a polygon with 8 sides

is an octagon. Therefore, the polygon

that has an interior angle sum of 1080°

is an octagon, or an 8 sided polygon.

To prove that {f € C°([0,1]) ||. f()dx = 0} is a vector space, we need to verify the following properties:

Closure under addition: Let f,g be two functions in {f € C°([0,1]) ||. f()dx = 0}. Then, for any x € [0,1], we have:

(f+g)(x) = f(x) + g(x)

Now, we can calculate the integral of (f+g)(x) from 0 to 1 as follows:

∫0^1 (f+g)(x) dx = ∫0^1 f(x) dx + ∫0^1 g(x) dx

Since f and g are in the set {f € C°([0,1]) ||. f()dx = 0}, we know that ∫0^1 f(x) dx = 0 and ∫0^1 g(x) dx = 0. Therefore, we have:

∫0^1 (f+g)(x) dx = 0

This means that f+g is also in the set {f € C°([0,1]) ||. f()dx = 0}, and thus the set is closed under addition.

Closure under scalar multiplication: Let f be a function in {f € C°([0,1]) ||. f()dx = 0} and let r be a scalar. Then, for any x € [0,1], we have:

(rf)(x) = r*f(x)

Now, we can calculate the integral of (rf)(x) from 0 to 1 as follows:

∫0^1 (rf)(x) dx = r*∫0^1 f(x) dx

Since f is in the set {f € C°([0,1]) ||. f()dx = 0}, we know that ∫0^1 f(x) dx = 0. Therefore, we have:

∫0^1 (rf)(x) dx = 0

This means that rf is also in the set {f € C°([0,1]) ||. f()dx = 0}, and thus the set is closed under scalar multiplication.

Existence of zero vector: The zero vector is the function f(x) = 0 for all x € [0,1]. This function clearly satisfies the condition that ∫0^1 f(x) dx = 0, and thus it is in the set {f € C°([0,1]) ||. f()dx = 0}.

Existence of additive inverse: Let f be a function in {f € C°([0,1]) ||. f()dx = 0}. Then, the additive inverse of f is -f(x) for all x € [0,1]. This function clearly satisfies the condition that ∫0^1 -f(x) dx = -∫0^1 f(x) dx = 0, and thus it is also in the set {f € C°([0,1]) ||. f()dx = 0}.

Since all the four properties are satisfied, we can conclude that {f € C°([0,1]) ||. f()dx = 0} is a vector space under the usual addition and scalar multiplication of functions.

Answer:

50%

Step-by-step explanation:

percent change = (new number - old number)/(old number) × 100%

Here, the new number is 2.

The old number is 4.

percent change = (2 - 4)/(4) × 100%

percent change = -2/4 × 100%

percent change = -50%

Since the percent change is negative, it's a percent decrease.

The percent decrease is 50%.

False, for both statements.

For the first statement, let A be an n x n matrix. If for two vectors y and z of Rⁿ we have Ay = Az, it does not necessarily mean that y=z. It is possible that A is a singular matrix, meaning that it does not have an inverse. In this case, there could be multiple vectors that would give the same result when multiplied by A. Therefore, it is not always true that y=z.

For the second statement, if A is a matrix of size n x n such that A³ = Iⁿ (where Iⁿ is the identity matrix of size n), it does not necessarily mean that A is invertible. It is possible for a matrix to have a power that equals the identity matrix, but not have an inverse. For example, consider the matrix A = [[0,1],[0,0]]. A² = [[0,0],[0,0]], and A³ = [[0,0],[0,0]], which is equal to I². However, A does not have an inverse, as its determinant is 0. Therefore, it is not always true that A is invertible if A³ = Iⁿ.

Answer:

There are 60 seconds in 1 minute, so in 5 1/2 minutes:

5 minutes x 60 seconds/minute = 300 seconds

1/2 minute x 60 seconds/minute = 30 seconds

Adding those together gives:

300 seconds + 30 seconds = 330 seconds

Therefore, there are 330 seconds in 5 1/2 minutes.

There are 330 seconds in 5 and 1/2 minutes. We find this by converting the minutes (both the whole and the half) into seconds and adding these amounts together.

To calculate the number of seconds in 5 and 1/2 minutes, we need to know the basic fact that 1 minute equals 60 seconds. With this, we can easily convert minutes to seconds by multiplying the number of minutes by 60.

First, let's convert the 5 whole minutes into seconds: 5 minutes x 60 seconds/minute = 300 seconds.

Next, let's convert the half minute: 1/2 minute x 60 seconds/minute = 30 seconds.

FInally, add these two amounts together: 300 seconds + 30 seconds = 330 seconds. Therefore, 5 and 1/2 minutes equals 330 seconds.

To find out how much of each mixture Donny should combine to make 6 kg of a mixture of 33% almonds, we need to use a system of equations. Let x be the amount of the first mixture and y be the amount of the second mixture.

The first equation represents the total amount of the mixtures:

x + y = 6

The second equation represents the amount of almonds in the mixtures:

0.40x + 0.25y = 0.33(6)

Solving the system of equations, we get:

0.40x + 0.25y = 1.98

0.40x + 0.25(6 - x) = 1.98

0.40x + 1.50 - 0.25x = 1.98

0.15x = 0.48

The interval on which the temperature was over 100°F is (0.79, 1.26).

To find the interval on which the temperature was over 100°F, we need to solve the inequality T(t) > 100.
First, let's rearrange the equation to isolate t:
T(t) = [4t / (t²+1)] + 98.6 > 100
[4t / (t²+1)] > 1.4
4t > 1.4(t²+1)
0 > 1.4t² - 4t + 1.4
Now we can use the quadratic formula to find the values of t that make this inequality true:
t = [-(-4) ± √((-4)² - 4(1.4)(1.4))] / [2(1.4)]
t = (4 ± √(16 - 7.84)) / 2.8

(3, 80)

(4, 95)

(4, 100)

And there is a line passing (0, 60) and (2, 80)

So we just need to find the y-intercept and the slope by the line:

Slope: [change in x over change in y] = 20 ÷ 2 = 10

y-intercept: [the value of y when x equal 0] = 60 (because the line passed through (0, 60) )

Answer; 10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test

Step-by-step explanation:

If "n is the positive integer, then n is even if and only if 7n + 4 will be even" is true.

To prove that we need to show the two things:

If n is even, then 7n+4 will be even.

If 7n + 4 is even, then n will be even.

Proof: Suppose that n is even. Then they exists an integer k such that n =2k. We can substitute this expression for n into 7n + 4 to get:

7n + 4 = 7(2k) + 4 = 14k + 4

= 2(7k + 2)

Since 7k + 2 is also an integer, we can see that 7n + 4 is even, since it is equal to twice an integer.

Now suppose that 7n + 4 is even. Then there exists an integer m such that 7n + 4 = 2m. We will rearrange this equation to have:

7n = 2m - 4

= 2(m - 2)

Since m - 2 is also an integer, we can see that 7n is even, since it is equal to twice an integer. Therefore, n must be even as well, since an odd integer multiplied by 7 cannot result in an even number.

Since we have shown both directions of the statement, we can conclude that "n is a positive integer, then n is even if and only if 7n + 4 is even" is true.
