Abboy has 800, he spend 160. What fraction of his original money does he have left

To determine the number of gallons of paint needed to cover office 143, we need to know the square footage of the office.

Once we have that information, we can divide the square footage by the coverage rate per gallon to calculate the required amount of paint.

Let's assume the square footage of office 143 is 800 square feet.

Number of gallons needed = Square footage / Coverage rate per gallon

Number of gallons needed = 800 square feet / 50 square feet per gallon

Number of gallons needed = 16 gallons

Therefore, you would need approximately 16 gallons of paint to cover office 143, assuming each gallon covers 50 square feet.

The given statement is False. A test statistic based on point estimation is not used to construct the decision rule which defines the rejection region.

In hypothesis testing, a test statistic is calculated using sample data and a specific hypothesis to assess the strength of evidence against the null hypothesis. The decision rule, which determines whether to reject or fail to reject the null hypothesis, is based on the test statistic's distribution under the null hypothesis, rather than the point estimate itself.

The construction of the decision rule involves selecting a significance level (alpha), which represents the probability of rejecting the null hypothesis when it is actually true. The rejection region is determined based on the chosen significance level and the distribution of the test statistic. If the calculated test statistic falls within the rejection region, the null hypothesis is rejected; otherwise, it is not rejected.

Point estimation, on the other hand, is used to estimate an unknown parameter of interest, such as the population mean or proportion, based on sample data. It involves calculating a single value (point estimate) that represents the best guess for the parameter value. The point estimate is not directly involved in constructing the decision rule or defining the rejection region in hypothesis testing.

False. A test statistic based on point estimation is not used to construct the decision rule that defines the rejection region.

The process of hypothesis testing involves constructing a decision rule to determine whether to accept or reject a null hypothesis based on sample data. The decision rule is typically defined using a critical region or rejection region, which is a range of values for the test statistic.

Point estimation, on the other hand, is a method used to estimate an unknown population parameter based on sample data. It involves calculating a single value (point estimate) that serves as an estimate of the population parameter.

While point estimation and hypothesis testing are both important concepts in statistics, they serve different purposes. Point estimation is used to estimate population parameters, whereas hypothesis testing involves making decisions based on sample data.

The decision rule for hypothesis testing is typically constructed based on the significance level (alpha) and the distribution of the test statistic, such as the t-distribution or the standard normal distribution. The test statistic is calculated using sample data and compared to critical values or calculated p-values to determine whether to reject the null hypothesis.

Therefore, the statement that a test statistic based on point estimation is used to construct the decision rule defining the rejection region is false.

The complete solution is:

∫4\(sin^{-1}(2x) dx = sin^{-1}(2x)\) x 4x + √(1 - (2x)²) + C, where C is the constant of integration.

We have,

\(u = sin^{-1)}(2x)\)

dv = 4 dx

Taking the derivative of u, we get:

du/dx = 1 / √(1 - (2x)²)

Integrating dv, we get:

v = ∫4 dx = 4x

Now, applying the integration by parts formula:

∫4 \(sin^{-1}(2x) dx\) = uv - ∫vdu

Plugging in the values, we have:

∫4 \(sin^{-})(2x) dx = sin^{-1}(2x) \times\) 4x - ∫(4x / √(1 - (2x)²)) dx

At this point, we need to evaluate the integral on the right side.

Let's perform a substitution to simplify it:

Let u = 1 - (2x)²

Differentiating u with respect to x, we get:

du/dx = -4(2x) = -8x

Solving for dx, we have:

dx = -du / (8x)

Substituting these values, the integral becomes:

∫(4x / √(1 - (2x)²)) dx = ∫(-4x / (8x x √u)) (-du / (8x))

Simplifying, we get:

∫(4x / √(1 - (2x)²)) dx = ∫(-1 / (2√u)) du

= -∫(1 / (2√u)) du

= -√u + C

Substituting back the value of u, we have:

∫(4x / √(1 - (2x)²)) dx = -√(1 - (2x)²) + C

Therefore,

Assuming that the arithmetic instruction took 4 cycles on average before the improvement, it would now take 3 cycles on average after the improvement.

Original time:

4 cycles

25% improvement:

0.75 * 4

= 3 cycles

The original time for an arithmetic instruction to execute was 4 cycles. To achieve a 25% improvement in performance, the time must be reduced by 25%. This can be calculated by subtracting 25% of the original time from the original time. In this case,

25% of 4 cycles is 1 cycle,

so 4 cycles minus 1 cycle equals 3 cycles.

Therefore, after the improvement, the arithmetic instruction will take 3 cycles on average to execute. No changes are made to the load/store and branch instructions.

The given natural deduction proof system is valid. The premises state that for all values of a, b, and c, if Y(a, b) and Y(b, c) are true, then Y(a, c) is also true. It also states that for all values of a and b, if Y(a, b) is true, then Y(b, a) is also true. Lastly, it states that for all values of a, there exists a value of b such that Y(a, b) is true. The conclusion is that for all values of a, Y(a, a) is true.

To prove the validity of the natural deduction proof system, we need to show that the conclusion is logically derived from the given premises.

1. Let's assume an arbitrary value for a and show that Y(a, a) holds.

2. From the third premise, we know that there exists a value of b such that Y(a, b) is true. Let's call this value of b as b1.

3. Applying the second premise to Y(a, b1), we get Y(b1, a).

4. Using the first premise, we have Y(b1, a) and Y(a, a), which implies Y(b1, a) and Y(a, b1), and consequently Y(b1, b1).

5. Now, we can use the first premise again with Y(b1, b1) and Y(b1, a) to obtain Y(a, a).

Since we have shown that for any arbitrary value of a, Y(a, a) holds, we can conclude that the given natural deduction proof system is valid. It establishes that for all values of a, Y(a, a) is true.

The system has a single solution and the solution set is (4,-7.5).

To use the elimination method, we need to eliminate one of the variables from the equations. We can see that if we multiply the first equation by -2, we can eliminate y:

-8x + 12 = 12y

5x + 4y = -10

Adding these two equations together eliminates y:

-3x + 12 = 0

Solving for x gives us:

x = 4

Now we can substitute this value of x back into either of the original equations to solve for y. Using the second equation:

5(4) + 4y = -10

20 + 4y = -10

4y = -30

y = -7.5

So the solution to the system is (4,-7.5).

The sum of the infinite geometric series –288 –216 –144 –72 is -1152.

The sum of an infinite number of terms having a constant ratio between successive terms is called as infinite geometric series.

Given series, -288, -216, -144, -72, ...

The sum of the infinite geometric series can be calculated as:

Sum = \(\dfrac{a}{1 -r}\)

Here, 'a' is the first term of the series and 'r' is the common ratio.

a = -288

The common difference can be calculated as:

r = \(\dfrac{(-216)}{(-288)}\)

= \(\dfrac{3}{4}\)

Substitute the values in the sum formula:

Sum = \(\dfrac{-288}{1 - \dfrac{3}{4}}\)

It can be simplified as:

Sum =  -288 \(\times\) 4

             = -1152
