which statement is true? group of answer choices dividing two integers results in integer division. with integer division, any fractional part of the calculation is lost. with integer division, any fractional part of the calculation is truncated. all of these.
Answers
All of these statements are true.
Dividing two integers results in integer division, which is a type of division where the result is always an integer. In integer division, any fractional part of the calculation is lost or truncated, meaning that it is not included in the final result. For example, if you divide 7 by 3 using integer division, the result would be 2, not 2.33333333. The fractional part of the calculation is simply discarded.
A positive integer equal to the quotient of the respective absolute values of the two integers, whether they are positive or negative, is the product of two positive or negative integers.
A negative integer is the result of the quotient of two positive integers. Its absolute value is the product of the integer's corresponding absolute values.

389.5÷1000
pls answer correctly
Answers
0.3895 Answer
Step-by-step explanation:
I thought you meant it on paper.
Answer:
0.3895
Step-by-step explanation:
Write out the division problem: 389.5 ÷ 1000.
Since we're dividing a decimal number by 1000, we can simply move the decimal point three places to the left to convert 1000 to 1.000: 389.5 ÷ 1.000.
Moving the decimal point three places to the left also means we need to add three trailing zeroes to the dividend: 389.5 becomes 389.500.
Now we can perform the long division: divide 3 by 1, write the quotient 3 above the 8, and subtract 3 from 8 to get 5 as the new remainder. Bring down the next digit 8 to get 58.
Divide 58 by 1, write the quotient 58 above the 9, and subtract 58 from 89 to get 31 as the new remainder. Bring down the next digit 5 to get 315.
Divide 315 by 1, write the quotient 315 above the decimal point, and subtract 315 from 389 to get 74 as the new remainder.
Since there are no more digits to bring down, we've reached the end of the long division. The final quotient is 0.3895.
Don't forget to include the decimal point in the answer, since we moved it three places to the left in step 2. The final answer is 0.3895.
So, 389.5 ÷ 1000 = 0.3895.

Suppose L=2,X=(−[infinity],[infinity])×R +
,≿ is represented by the utility function u(x)=x 1
+ln(1+x 2
). Show that it is quasilinear. Is it convex? Strictly convex? Homothetic?
Answers
a. The function is not strictly convex.Now, let's check the homotheticity of the function. A function is homothetic if it is continuous, quasiconcave and there exists a positive function, v(x1), such that u(x)=v(x1)f(x2). b. We can say that the function is homothetic.
We are also given the values of L, X and the utility function. The values are\(L=2,X=(−[infinity],[infinity])×R +,\)≿ is represented by the utility function\(u(x)=x 1+ln(1+x 2).\)
Let's solve this.
Suppose the utility function u(x) is represented as:
\(u(x)=x 1+ln(1+x 2)\)
We can see that the utility function is quasilinear. It has a linear component in x1 and a quasi-linear component in x2.
Therefore, we can say that the utility function is quasilinear.Now, let's check the convexity of the utility function. We will find the Hessian matrix and check its properties. The Hessian matrix is given by: H = [0 0; 0 1/(1+x2)^2]The determinant of \(H is 0(1/(1+x2)^2)-0(0) = 0\), which is neither positive nor negative.
Hence, the Hessian matrix is neither positive definite nor negative definite.
Therefore, we cannot determine whether the function is convex or concave.
However, we can check the strict convexity of the function by checking if the Hessian matrix is positive definite or not. The eigenvalues of the Hessian matrix are 0 and \(1/(1+x2)^2\), which are non-negative.
Hence, the Hessian matrix is positive semi-definite.
Therefore, the function is not strictly convex.Now, let's check the homotheticity of the function. A function is homothetic if it is continuous, quasiconcave and there exists a positive function, v(x1), such that \(u(x)=v(x1)f(x2)\)
If we take \(v(x1) = x1, then u(x)=x1(1+ln(1+x2)) = x1ln(e^(1+x2)) = ln(e^(1+x2)^x1)\)
Therefore, we can say that the function is homothetic.

Answer:
\( \frac{13}{35} \)
Step-by-step explanation:
To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).
\( \frac{4}{5 } - \frac{3}{7} \)
\( \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} \)
\( \frac{28}{35} - \frac{15}{35} \)

A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 31 ft/s. Its height in feet after t seconds is given by y = 31 t − 23 t 2 . A. Find the average velocity for the time period beginning when t=1 and lasting .01 s: .005 s: .002 s: .001 s: NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator. Estimate the instanteneous velocity when t=1.
Answers
The average velocity for the time period is -15 feet per second
The velocity of the ball = 31 feet / seconds
The function of the height is
y = 31t - 23t^2
Time period beginning when t = 1 and lasting .01 s, .005 s, .002 s, .001 s
The average velocity = f(1.01) - f(1) / 1.01 - 1
f(t) = 31t - 23t^2
f(1.01) = 31(1.01) - 23(1.01)^2
= 31.31 - 23.46
= 7.85 feet per second
Similarly
f(1) = 31(1) - 23(1)^2
= 31 - 23
= 8 feet per second
The average velocity = 7.85 - 8 / 1.01 - 1
= -0.15 / 0.01
= -15 feet per second
Hence, the average velocity for the time period is -15 feet per second

what results In ridge regression, choosing a very large \lambdaλ penalty strength
Answers
In ridge regression, the penalty strength parameter, represented by \lambda», controls the trade-off between fitting the training data well and keeping the model coefficients small.
When a very large penalty strength is chosen, it results in a higher degree of shrinkage of the regression coefficients towards zero. This means that the model becomes less complex and less likely to overfit the training data. However, it also means that the model may become too biased towards the null hypothesis, leading to underfitting and decreased predictive power. Therefore, choosing the right value of \lambdaλ is crucial for achieving optimal performance in ridge regression.
In ridge regression, choosing a very large λ (lambda) penalty strength results in a higher regularization effect, which helps to reduce overfitting by shrinking the coefficients of the independent variables towards zero. This helps to create a more generalized model by controlling the complexity of the model. However, choosing a λ value that is too large can also result in underfitting, as the model may become too simple to capture the underlying relationships in the data effectively.

3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
However, there are no parentheses or exponents in this expression, so we can skip to the next step.
Next, we need to perform the multiplication and division operations, from left to right. The expression only contains multiplication, so we can perform it directly:
4 x 2 = 8
-2 x 2 = -4
Substituting these values back into the expression, we get:
4 x 2 + 1 - 2 x 2 + 2 = 8 + 1 - 4 + 2
Finally, we can perform the addition and subtraction operations, from left to right:
8 + 1 = 9
9 - 4 = 5
5 + 2 = 7
Therefore, the value of the expression is 7.

statistics computed for larger random samples are less variable than the statistic computed for smaller random samples
Answers
Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.
This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.
The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.
In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.
