The percentage of salt in green beans can is 2.89%.

It is important to know about the percentage first, the percentage is a part of the sample in the population. It can be determined by this formula

A% = x / N . 100%

where A% is the percentage, x is the sample and N is the total population

From the question above, we know that :

x = 11.5 grams

N = 14 ounce = 396.89 grams

By substituting the parameter to the equation, we get

A% = x / N . 100%

A% = 11.5 / 396.89 . 100%

A% = 2.89%

Hence, the total salt in the can is 2.89%

Step-by-step explanation:

To change to spherical coordinates, we can use the following formula:

x = ρ sin φ cos θ

y = ρ sin φ sin θ

z = ρ cos φ

We also note that the region of integration is a hemisphere with radius 3, and that the integrand contains x^2z+y^2z+z^3. Since we are integrating over a hemisphere, the bounds of ρ can be from 0 to 3, φ can be from 0 to π/2, and θ can be from 0 to 2π.

Next, we need to express the integrand in terms of ρ, φ, and θ. Substituting x, y, and z, we get:

x^2z + y^2z + z^3 = ρ^4 sin^2 φ cos^2 θ (ρ cos φ) + ρ^4 sin^2 φ sin^2 θ (ρ cos φ) + (ρ cos φ)^3

Simplifying, we get:

x^2z + y^2z + z^3 = ρ^5 cos^2 φ + ρ^3 cos^3 φ

Thus, the new integral is:

∫0^(2π) ∫0^(π/2) ∫0^3 (ρ^5 cos^2 φ + ρ^3 cos^3 φ) ρ^2 sin φ dρ dφ dθ

Integrating with respect to ρ, we get:

∫0^(2π) ∫0^(π/2) [ 1/6 ρ^6 cos^2 φ + 1/4 ρ^4 cos^3 φ ]_|ρ=0^3 sin φ dφ dθ

Simplifying and integrating with respect to φ, we get:

∫0^(2π) [ 9/5 sin^5 φ - 27/14 sin^7 φ ]_|φ=0^(π/2) dθ

Evaluating the limits, we get:

∫0^(2π) [ 9/5 - 27/14 ] dθ

Finally, evaluating the integral, we get:

∫0^(2π) [ 33/35 ] dθ = 66π/35

Therefore, the value of the integral after changing to spherical coordinates is 66π/35.

Step-by-step explanation:

7x−3(x−6)=2

Distribute

7x -3x + 18 = 2

4x +18 =2

Subtract 18 from each side

4x +18-18 = 2-18

4x = -16

Divide by 4

4x/4 = -16/4

x = -4

To simplify a complex fraction expression, first identify the numerator and denominator of each fraction.

A complex fraction is a fraction that contains one or more fractions in the numerator, denominator, or both. This type of fraction requires additional steps to simplify and can often be reduced to a simpler fraction or a whole number. Complex fractions are also known as compound fractions or nested fractions.

Then, factor each fraction into its simplest form by dividing each numerator and denominator by their greatest common factor. Finally, combine the fractions by multiplying the numerators and denominators. This will result in a simplified expression.

If Marsha bought a new car for $21152.25 and picked cost is $2150 and sales tax is $1007.25 , then the base price of Marsha's car is $17995  .

the price that Marsha paid for the car is = $21152.25   ;

the picked cost for the car is = $2150  ;

the sales tax for the car is = $1007.25  ;

the formula to calculate the Marsha's car is = (Amount Paid) - (Picked Cost + Sales tax) ;

substituting the values ,

we get ;

= 21152.25 - (2150 + 1007.25 )

Step-by-step explanation:

The vector vectdata will retain its original size of 90, and none of the provided answer choices (89, 2, 88, 90) are correct.

The code snippet you provided has a syntax error. The correct syntax to call the pop_back function on a vector is vectdata.pop_back(), with parentheses at the end. However, in the given code, the parentheses are missing, causing a compilation error.

Assuming we fix the syntax error and call the pop_back() function correctly, the size of the vector vectdata would be reduced by one. The pop_back() function removes the last element from the vector. Since the vector was initially created with a size of 90 using vector vectdata(90), calling pop_back() will remove one element, resulting in a new size of 89.

However, in the given code snippet, the missing parentheses make the line vectdata. pop_back an invalid expression, preventing the code from compiling successfully. Therefore, the vector vectdata will retain its original size of 90, and none of the provided answer choices (89, 2, 88, 90) are correct.

Therefore, Mario's winnings of 177 dollars is approximately 2.92 standard deviations below the mean.

We can calculate the number of standard deviations that Mario's winnings of 177 dollars is from the mean using the formula:

z = (x - μ) / σ

where x is the value we want to convert to standard deviations, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

In this case, Mario's winnings of 177 dollars is the value we want to convert to standard deviations, the mean is μ = 323 dollars, and the standard deviation is σ = 50 dollars. Substituting these values into the formula, we get:

z = (177 - 323) / 50

= -2.92

This form of the equation is useful because it shows that any periodic function of time can be represented as a sum of sine and cosine functions with different amplitudes and phases.

We can show that acos(wt) + bsin(wt) can be written in the form Rsin(wt + φ) where R and φ are constants and R is the amplitude of the wave.

Using the trigonometric identity sin(a+b) = sin(a)cos(b) + cos(a)sin(b), we can write:

acos(wt) + bsin(wt) = R(sin(wt+φ)),

where R = √(a^2+b^2) and φ = tan⁻¹(b/a).

To see how this works, we can use the values of a = 3 and b = 4 as an example:

acos(wt) + bsin(wt) = 3cos(wt) + 4sin(wt)

R = √(a^2+b^2) = √(3^2 + 4^2) = 5

φ = tan⁻¹(b/a) = tan⁻¹(4/3)

So we can rewrite the equation as:

acos(wt) + bsin(wt) = 5sin(wt + tan⁻¹(4/3))

This form of the equation is useful because it shows that any periodic function of time can be represented as a sum of sine and cosine functions with different amplitudes and phases. It is also helpful in analyzing the properties of waves, such as their amplitude and frequency.

Step-by-step explanation:

Opportunity cost increases along the production possibility frontier because of the principle of diminishing returns.

Diminishing returns refer to the fact that as we allocate more resources to the production of one good, the marginal productivity of those resources decreases. In other words, as we produce more of one good, it becomes increasingly difficult and costly to produce additional units of that good.

As we move along the PPF, we are producing more and more of one good and less and less of the other. The resources that were previously used to produce the other good are now being used to produce more of the first good. As we move along the PPF, we are sacrificing more and more of the second good in order to produce additional units of the first good, and this is reflected in the opportunity cost. The opportunity cost of producing one good increases as we move along the PPF.

An inscribed angle is formed by two chords of a circle that intersect at a vertex located on the circle.

The angle itself is formed by the two sides of the angle, which are the line segments connecting the vertex to the endpoints of the chords. The property that makes inscribed angles interesting is that the measure of an inscribed angle is half the measure of the intercepted arc on the circle.

This relationship holds true for any inscribed angle in a circle, making it a useful concept in geometry for solving problems involving angles, arcs, and circles.

The proper way to construct a stem-and-leaf plot to display the data set {62,67,68,73, 73, 79,91,94,95,97} is to include a stem labeled ‘8’ and enter no leaf on the stem. So, the correct choice is option (b).

A stem and leaf graph is like a special table where each data value is separated into a "stem" (the first number) and a "leaf" (usually the last number). Leaves are sorted in ascending order from left to right. We have a data set with values {62,67,68,73, 73, 79,91,94,95,97}. Now, to construct the stem- leaf plot for our data.

Stem | Leaf

6 | 2 7

7 | 3 3 9

9 | 1 4 5 7

For stem and leaf diagram if some values are not present for some stem, then no leaf should be added to that stem. If we skip that stem than it would distort the shape of distribution of the data.
