Step 1:

They spilt 1/5 on the way to the lemonade stand.

180 x 1/5

= 180/5

= 36

So they spilt 36 cups of lemonade on the way to the stand.

Number of cups left = 180 - 36

= 144

Step 2:

They sold 75% of 144 cups of lemonade

75/100 x 144      (divide both 75 and 100 by 25)

= 3/4 x 144         (divide 144 by 4)

= 3 x 36

= 108

So they sold 108 cups of lemonade.

Number of cups left = 144-108

= 36

Step 3:

They spilt 1/3 of 36 cups of lemonade on the way home.

36 x 1/3

= 36/3

= 12

Therefore they brought back 12 cups of lemonade home.

Answer:

A. 12 cups

Step-by-step explanation:

1/5 of 180 is 36

to find 1/5 of something multiply it by 1/5

1/5 * 180 = 36

180 - 36 = 144

they have 144 cups after spilling 1/5

75% of 144 is 108

to find 75% of something is to multiply the number by 0.75

0.75 * 144 = 108

to find the remaining lemonade subtract sold from remaining

144 - 108 = 36

1/3 of 36 is 12

to find 1/3 of something multiply the number by 1/3

1/3 * 36 = 12

12 cups made it to the house

your answer is A.

The surface area of the cylinder is 18.84 square feet

The given parameters are

Height, h = 2 ft

Diameter, d = 2 ft

The radius (r) is half of the diameter (d)

This is calculated as:

Radius = Diameter/2

So, we have:

r = d/2

Substitute 2 for d

r = 2/2

Evaluate the quotient i.e. divide 2 by 1

r = 1

The surface area is then calculated using the following formula

A = 2πr² + 2πrh

Substitute the given values in the above equation

So, we have:

A = 2 * 3.14 * 1^2 + 2 * 3.14 * 1 * 2

Evaluate the exponents

A = 2 * 3.14 * 1 + 2 * 3.14 * 1 * 2

Evaluate the products

A = 6.28 + 12.56

Evaluate the sum

A = 18.84

Hence, the surface area of the cylinder with the given height and radius is 18.84 square feet

Step-by-step explanation:

Answer:

a) 375

b) 7062.75 mm²

Step-by-step explanation:

b) We need to find the shortest possible width and length to get the smallest possible area.

To get the boundaries for 19.4, we go on to the next significant figure (the hundredths) and ± 5 of them.

The boundaries are, therefore: 19.35 - 19.45

As for the length, we can see they've added 5 units as the measurement is correct to 2 sig' figures, which is the tens.

And so, if we do as we did before, we go to the next sig' figure (the units) and ± 5 of them, we get the boundaries to be 365 - 375.

Now, we just multiply the lower bounds of the length and width to get the minimal/lower-bound area:

365 * 19.35 = 7062.75 mm²

Just substract simple

The elements of the Hessian matrix for the function f(x, y) = (x² − y)(2x² − y) at the initial point (3, 2.7) are: a=127.80, b=-18.00, c=-18.00, and d=127.80.



The Hessian matrix is a square matrix of second-order partial derivatives. For the given function f(x, y) = (x² − y)(2x² − y), we need to calculate the second-order partial derivatives with respect to x and y and evaluate them at the initial point (3, 2.7).

The Hessian matrix is defined as:H = [[∂²f/∂x², ∂²f/∂x∂y],

    [∂²f/∂y∂x, ∂²f/∂y²]]

Taking the partial derivatives of f(x, y) with respect to x and y, we get:

∂f/∂x = 4x³ - 4xy

∂f/∂y = -2x² + 2y

Next, we calculate the second-order partial derivatives:

∂²f/∂x² = 12x² - 4y

∂²f/∂x∂y = -4x

∂²f/∂y∂x = -4x

∂²f/∂y² = 2

Now we substitute the initial point (3, 2.7) into these expressions:

∂²f/∂x² = 12(3)² - 4(2.7) = 108 - 10.8 = 97.2

∂²f/∂x∂y = -4(3) = -12

∂²f/∂y∂x = -4(3) = -12

∂²f/∂y² = 2

Therefore, the elements of the Hessian matrix at the initial point (3, 2.7) are:

H = [[97.2, -12],

    [-12, 2]]

So, the correct answer is a=127.80, b=-18.00, c=-18.00, and d=127.80.

Based on the information in the graph, the angles of the parallelogram would be 68° and 112°, while the length of its sides would be 15 and 8.

To identify the length and angles of this figure we must carefully look at the lengths shown and the angles shown. Taking into account the shape of the parallelogram, we can infer that the values that correctly complete the dimensions of the figure are:

This is because the parallelogram has two equal sides and equal bases, so if the upper one measures 15, the lower one must measure the same. Additionally, if the side measures 8 the other side must measure 8. In the case of the angles it would be the same.

The change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.

Nominal exchange rate is the price of one currency in terms of another currency. It represents the number of units of one currency that can be purchased with a single unit of another currency. In Canada's perspective, a change in nominal exchange rate means the value of the Canadian dollar in US dollars. So, to calculate the change in nominal exchange rate from Canada's perspective.

Nominal Exchange Rate = Real Exchange Rate x (1 + Inflation of Canada) / (1 + Inflation of US) Given, Real Exchange Rate of Canada

= 4.9% Inflation of Canada

= 8.5% Inflation of US

= 3.8%  Nominal Exchange Rate

= 4.9% x (1 + 8.5%) / (1 + 3.8%) Nominal Exchange Rate

= 4.9% x 1.085 / 1.038 Nominal Exchange Rate

= 5.3099 / 1.038 Nominal Exchange Rate

= 5.11 (rounded to two decimal places)

This means that if there were no inflation, the nominal exchange rate from Canada's perspective would have been 5.11 Canadian dollars per US dollar. But due to inflation, the Canadian dollar depreciated by 2.76% (calculated as (5.11 - 4.97) / 5.11 x 100%). Therefore, the change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.

Question:

Workers at a certain soda drink factory collected data on the volumes​ (in ounces) of a simple random sample of 18 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.14 oz, and they appear to be from a normally distributed population.

If the workers want the filling process to work so that almost all cans have volumes between 12.02 oz and 12.66 ​oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.16 oz. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.16 oz. Use a 0.01 significance level. Complete parts​ (a) through​ (d) below.

a. Identify the null and alternative hypotheses.  

b. Compute the test statistic.

c. Find the p-value.

d. State the conclusion.

Answer:

Null hypotheses = H₀: σ = 0.16  oz

Alternate hypotheses = H₁: σ < 0.16  oz

Critical value = 6.408

Chi-square value = \(\chi^2\) = 13.016

Reject H₀  Since \(\chi^2\) > Critical value

Reject H₀ Since p-value ≤ α

We have significant evidence at given significance level that the population of volumes has a standard deviation of less than 0.16 oz.

Step-by-step explanation:

Set up hypotheses:

The null hypotheses is that the population of volumes has a standard deviation of 0.16 oz

Null hypotheses = H₀: σ = 0.16  oz

The claim to be tested is that the population of volumes has a standard deviation of less than 0.16 oz

Alternate hypotheses = H₁: σ < 0.16  oz

Determine type of test:

Since the alternate hypothesis states that the population of volumes has a standard deviation of less than 0.16 oz, therefore we will use a lower-tailed chi-square test.

Determine the Critical value:

Given level of significance = 0.01

Since it is a lower-tailed test, the areas given in the chi-square table are the areas to the right of the critical value. To get the areas on the left, subtract it from  one, and then look it up

α = 1 - 0.01 = 0.99

degree of freedom = df = n - 1 = 18 - 1 = 17

The critical value from the chi-square table at α = 0.99 and df = 17 is found to be

Critical value = 6.408

Using an online “chi-square p-value calculator”

The left tail p-value for df = 17 and Critical value = 6.408 is found to be

p-value = 0.01

Set up decision rule:

Reject H₀ If  > Critical value

We reject the Null hypothesis If the calculated chi-square value is more than the critical value.

OR

Reject H₀ If p-value ≤ α

Compute the test statistic:

\($ \chi^2 = \frac{(n-1) s^2}{\sigma^2} } $\)

\($ \chi^2 = \frac{(18-1) 0.14^2}{0.16^2} } $\)

\(\chi^2 = 13.016\)

Conclusion:

We reject H₀

Since \(\chi^2\) > Critical value

13.016 > 6.408

Also

p-value ≤ α

0.01 ≤ 0.01

We have significant evidence at given significance level that the population of volumes has a standard deviation of less than 0.16 oz.
