Step-by-step explanation:

Given, Giada buys her bagels for $0.90 and sells them for $2.00. Unsold bageis are discarded. The following table shows the demand for Asiage Bagels and the number of days with these sales. Demand for Asiage  |Number of Days with These Sales40|5 30|5.

Therefore, the expected number of bagels Giada can sell in a day,

µ = (40*5 + 30*5)/(5+5)= 350/10 = 35.

Now the expected revenue,

R = 35 * $2.00 = $70.00

The cost of ordering 30 bagels is $0.90 * 30 = $27.00Therefore, her expected profit is given by the formula:

Profit = Revenue - CostProfit = $70.00 - $27.00 = $

Giada can expect a profit of $43.00 (rounded to the nearest cent if needed).The given question requires a long answer as the answer involves the calculation of expected revenue, expected cost, and expected profit.

the length of the curve, correct to four decimal places, is L = 30.

To find the length of the curve, we need to evaluate the integral of the magnitude of the derivative of r(t) with respect to t over the given interval.

Given:

r(t) = (√t, t, t²)

Interval: 3 ≤ t ≤ 6

To find the magnitude of the derivative of r(t), we first need to calculate the derivative of r(t) with respect to t:

r'(t) = (1/2√t, 1, 2t)

The magnitude of r'(t) is given by:

|r'(t)| = √((1/2√t)² + 1² + (2t)²)

       = √(1/4t + 1 + 4t²)

       = √(4t² + 4t + 1)

       = 2t + 1

Now, we can calculate the length of the curve by evaluating the integral of |r'(t)| over the given interval:

L = ∫[3, 6] (2t + 1) dt

Integrating, we get:

L = [t² + t] evaluated from t = 3 to 6

L = (6² + 6) - (3² + 3)

L = (36 + 6) - (9 + 3)

L = 42 - 12

L = 30

The correct option is for the value of c,  such that f(c) is the average value of the function on the interval [0, 2], is D.

The average value of a function on an interval [a, b] is given by:

R = (f(b) - f(a))/(b - a)

Here the interval is [0, 2], then:

f(2) = √(2 + 2) = 2

f(0) = √(0 + 2) = √2

Then here we need to solve the equation:

√(c + 2) = (f(2) - f(0))/(2 - 0)

√(c + 2) = (2 + √2)/2

Solving this for c, we will get:

c = [ (2 + √2)/2]² - 2

Answer:

(2, –3) is a solution to the system of linear equations.

Step-by-step explanation:

Given: Equations:

3x - y = 9 --------(1),

4x + y = 5 --------(2),

Add Equation (1) + Equation (2),

3x + 4x = 9 + 5

7x = 14  ( Combine like terms )

x = 2   ( Divide both sides by 7 ),

From equation 1:

At a significance level of 0.01, coefficients that have p-values less than 0.01 are considered significantly nonzero. These coefficients indicate a statistically significant relationship between the predictor variable and the response variable.

To determine which coefficients are significantly negative, we need to look at the sign of the coefficient estimate. If the coefficient estimate is negative and the p-value is less than 0.01, we can conclude that the coefficient is significantly negative.

In regression analysis, the p-value represents the probability of obtaining a test statistic as extreme as the observed one, assuming the null hypothesis is true. If the p-value is less than the significance level (0.01 in this case), we reject the null hypothesis and conclude that the coefficient is significantly different from zero. Additionally, the sign of the coefficient tells us the direction of the relationship. A negative coefficient suggests a negative relationship between the predictor and the response variables. Therefore, coefficients with p-values less than 0.01 and a negative estimate are significantly negative.

Step-by-step explanation:

The number zero is neither positive or negative; hence there is no sign.

Answer:

10 i belive

Step-by-step explanation:

Hence, the five positive integers are 2, 2, 4, 4, 13.

Mean- The arithmetic mean of a given data is the sum of all observations divided by the number of observations.

Median-The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.

Mode-The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.

According to the question , it can be concluded that the total no. of observations are 5.

So , Let n=5

Let  the integers be a, b, c, d and e

The question says that mode(s) are 2  and 4.

This indicates that 2 and 4 both have occurred more than once , and both have same frequency since both are modes.

Since we have only 5 integers , and 2 and 4 both are modes , so both these numbers have possibility to occur only twice.

Hence , it becomes , a=2 , b=2 , c=4 , and d=4

Hence we can say that out of five required integers ,four of them are 2 and 4.

Further , we are given that mean is 5.

therefore , using formula:

Mean = Sum of Observations / Number of observations(n)

Mean=  (a+b+c+d+e) / 5

5 = (2+2+4+4+e) / 5

5 = (12+e)/5

Multiplying both sides by 5 , we get :

25 = 12+e

e=25-12

Hence , e = 13

So,  the five positive integers are 2, 2, 4, 4, 13.

Answer: B=1

Step-by-step explanation:

∠MHL and ∠MHJ are supplementary angles that is some of the measure of both angle is 180°, because these angle are on a line.

∠MHL + ∠MHJ = 180°

substituting values.

⟹ (2m + 10)° + (5m + 100)° = 180°

⟹ 5m + 2m + 10 + 100 = 180°

⟹ 7m + 110 = 180°

⟹ 7m = 180° - 110°

⟹ 7m = 70°

⟹ m = 70/7

⟹ m = 10

m = 10°

measure of ∠MHL is

⟹ (2m + 10 )°

⟹ 2(10°) + 10°

⟹ 20° + 10°

For the absolute value function g(x) = |x + 2| + 1, h must be negative and k must be positive.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

We know the coordination of the vertex of an absolute value function

g(x) = |x - h| + k is, (h, k).

Given, An absolute value function has vertex coordinate (- 2, 1).

Therfore the absolue value function g(x) = |x - (-2)| + 1.

The idea of the Laffer Curve, as it is expressed mathematically, is that there is an optimal tax rate at which the government can maximize revenue. This concept is based on the idea that as tax rates increase, revenue collected by the government initially increases but eventually reaches a point at which further increases in tax rates lead to a decrease in revenue.

The Laffer Curve is used to analyze how economic policies may affect growth and stability by illustrating the trade-off between higher tax rates and revenue generation. It is often used as an argument to reduce the government's role in the economy, as increasing taxes beyond a certain point can be counterproductive.

Additionally, the Laffer Curve is related to the idea that aggregate supply increases when production costs decrease, as lower taxes can lead to lower production costs and, therefore, an increase in supply. This is a long answer that describes the various aspects of the Laffer Curve.
