Lucas ate a fraction of a pizza. Hugo ate 5/8 of the same pizza. Now there is 1/8 of the pizza left what fraction of pizza did Lucas eat?
Answers
Answer:
\(\frac{2}{8}\)
Step-by-step explanation:
In order to solve this equation we will need to use what we know in order to find the answer.
\(1=\frac{8}{8}\)
\(H=\frac{5}{8}\)
\(R = \frac{1}{8}\)
If Huge ate 5/8's of the pizza and 8/8's creates a whole pizza then the question is quite simple. There is only 1/8's remaining after the boys finish their meal but 5/8's of the pizza was already eaten by Hugo meaning Lucas has to eat 2/8's of the pizza in order for there to be only 1/8's of the pizza left which means 2/8's is your answer.
Hope this helps.

D. The mean will increase and the median will remain the same
Step-by-step explanation:
First I’d order them from smallest to largest in the data set:
3, 5, 6, 6, 7, 11
The median here is 6.
Then the mean would be 6.33
Then it says if 3 is removed:
5, 6, 6, 7, 11
So we would know the median is 6
The mean here would be 7
So we can see the mean increases but the median stays the same, therefore the answer is D
a data analyst is using statistical measures to get a better understanding of their data. what function can they use to determine how strongly related are two of the variables?
Answers
The correlation coefficient can be used to get a better understanding and to determine the extent of a strong relation between two variables.
In a statistical setting, two or more variables are said to be connected if their values fluctuate in such a way that as the value of one variable rise or falls, the value of the other variable does the same (although it may be in the opposite direction).
For instance, there is a relationship between the two variables "hours worked" and "revenue earned" if a rise in hours worked is correlated with an increase in income earned. When considering the two factors "price" and "purchasing power," the ability of a person to purchase items reduces as the price of those goods rises (assuming a constant income).

If a=-2x-ia=-2x-i and b=3ib=3i, then find the value of the ab^(3)ab 3 in fully simplified form.
Answers
The value of ab^3, where a = -2x - i and b = 3i, can be found by substituting the given values into the expression. The fully simplified form of the expression is -54xi^4.
The value of ab^3, we substitute the given values for a and b into the expression:
ab^3 = (-2x - i)(3i)^3
Simplifying further:
ab^3 = (-2x - i)(27i^3)
Since i^2 = -1 and i^3 = -i, we can rewrite the expression as:
ab^3 = (-2x - i)(27(-i))
Multiplying the coefficients:
ab^3 = -54x(-i)
Simplifying further, we have:
ab^3 = 54xi
Therefore, the value of ab^3, where a = -2x - i and b = 3i, is 54xi.

Which of the following accurately describes the effect of increasing the sample size? Increases the standard error. Decreases the standard error. No effect on standard error. Has effect on standard error, but other factors determine whether the increased sample size increase or decrease standard error.
Video Answe
Answers
Increasing the sample size has an effect on the standard error, but other factors determine whether the increased sample size will increase or decrease the standard error.
The standard error is a measure of the variability of the sample mean. When the sample size is increased, the standard error generally decreases because a larger sample size provides more precise estimates of the population mean. However, other factors such as the variability of the population and the sampling method used can also affect the standard error.
For example, if the population variability is high, increasing the sample size may not have a significant impact on reducing the standard error. On the other hand, if the population variability is low, increasing the sample size can lead to a substantial decrease in the standard error.
In summary, increasing the sample size generally decreases the standard error, but the magnitude of this effect depends on other factors such as population variability and sampling method.

the function has a critical point at . what is the value of the hessian matrix at this critical point? what type of critical point is it? ? g
Answers
To determine whether a critical point is a local minimum, maximum, or saddle point, one can find the Hessian matrix of the function at that point and analyze its eigenvalues.
To determine the critical point of a function, one needs to find the values of its independent variables that make the gradient zero. The Hessian matrix is the matrix of second-order partial derivatives of a function, and it can help determine the nature of a critical point.
Given a function, if the Hessian matrix evaluated at a critical point has all positive eigenvalues, then the function has a local minimum at that point. If the Hessian matrix has all negative eigenvalues, the function has a local maximum at that point. If the Hessian matrix has a mix of positive and negative eigenvalues, then the point is a saddle point. If the Hessian matrix has some zero eigenvalues, then the test is inconclusive and higher-order derivatives must be examined.
It is possible to find the Hessian matrix for any given function and evaluate it at a critical point to determine its nature. By analyzing the eigenvalues of the Hessian matrix, one can identify whether the critical point is a local minimum, maximum, or saddle point.

Substitute a cumulative area of 0.2420 , a mean of 0, and a standard deviation of 1 into the inverse normal distribution. Use technology to calculate the z-score, rounding to two decimal places
Answers
Substituting a cumulative area of 0.2420, a mean of 0, and a standard deviation of 1 into the inverse normal distribution, the z-score is -0.71 to two decimal places.
Given that the cumulative area of 0.2420, a mean of 0, and a standard deviation of 1, the required z-score has to be determined.We know that the standard normal distribution with mean 0 and standard deviation 1 is denoted as N(0, 1). The inverse normal distribution with a cumulative area of x is the inverse of the normal distribution with cumulative area x. Let z be the z-score corresponding to a cumulative area of x, then we can say that P(Z ≤ z) = x, where P is the cumulative distribution function of the standard normal distribution.
Substituting the given values in the formula, we get:0.2420 = P(Z ≤ z)We need to find the corresponding z-value using inverse normal distribution. Therefore, we take the inverse of the cumulative distribution function, as follows:z = invNorm(0.2420)z = -0.71 (rounded to two decimal places)Thus, the required z-score is -0.71.

Answers
Answer:
\(5A + 4P = 10\)
\(5A + 5P = 11\)
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
\(5A + 4P = 10\)
For me, the expression is
\(5A + 5P = 11\)
Hence, the system of equation is:
\(5A + 4P = 10\)
\(5A + 5P = 11\)
Solving for the values of A and P.
Substract equation (2) from (1)
\(5A - 5A + 4P - 5P = 10 - 11\)
\(-P = -1\)
\(P = 1\)
Hence, 1 pear costs $1
Substitute 1 for P in \(5A + 4P = 10\)
\(5A + 4 * 1 = 10\)
\(5A + 4 = 10\)
\(5A = 10 - 4\)
\(5A = 6\)
\(A = \frac{6}{5}\)
\(A = \$1.2\)
Hence, 1 apple costs $1.2

Xaoting buys 3 pairs and notices that the socks do not ring up at the advertised sale price, so she has the cashier do a price check. If the sales tax is 8%, how much does Xaoting save by paying attention at the register? a. $3. 66 b. $4. 50 c. $4. 86 d. $5. 70.
Answers
The Xaoting will save $4.86
We have to find how much Xaoting will save
Therefore we need to calculate the prices of the socks without the advertised sales price.
We have given that $5.00 per pair,
Xaoting buys 3 pairs and notices that the socks do not ring up at the advertised sale price. and sales tax is 8%.
$5.00 per pair x 3 = $15
Sales tax = 8% or 0.08
What is the formula for total price?
Total price=total fixed cost+ total variable cost
Therefore,
Total price=total fixed cost+total variable cost
= (15.00 x 0.08) + 15.00
= 1.20 + 15.00
= $16.20
Total price = $16.20
Now have to find how much it would be if the socks were on the advertised price.
Advertise on sale for $3.50 per pair
So,
$3.50 x 3 = $10.50
Advertised Total price = (10.50 x 0.08) + 10.50
= 0.84 + 10.50
= $11.34
So,
To find how much Xaoting will save by subtracting the regular price to the advertised price.
Savings = $16.20 - $11.34
= $4.86
Therefore,
The Xaoting will save $4.86

So the family decrease their consumption of sugar by 2kg
Step 2: We have to find what percent did the family reduce their sugar consumption
We can divide how much they reduced by with the original amount
2kg/10kg = 1/5 kg or 20%
