The answer is D) 40% because when you add the people who were already accounted for, it comes to 150, which is 60% of 250. So the remaining attendees, children 12 and under, makes up the rest of the 250, which was 40%.

Answer: d) 40%

Step-by-step explanation:

Given, Total people attended the first showing of a play = 250

Number of adults above the age of 40= 75

Number of people between the ages 20 & 40 = 50

Number of teenagers ages 13-19 =25

Total people other than children ( age of 12 and under) = 75+50+25 =150

Then, the number of children ( age of 12 and under) = 250-150=100

Now , the percentage of the attendees were children 12 and under will be

\dfrac{\text{Number of children}}{\text{Total attendees}}\times100\\\\=\dfrac{100}{250}\times100\\\\=40\%

Hence, the correct answer is d) 40%.

In a fruit juice recipe, the ratio by volume of orange juice to pineapple juice to apple juice is 2:7:5. How many
Vlad [161]
If orange:pineapple:Apple juice ratio is
2:7:5, pineapple juice would make up 7/14 of the whole juice mixture, which equals to 1/2. 1/2 of 3 litres = 1.5 litres
1.5/3 = 1/2
The answer would be B (1/2)

With the aid of an illustrative example, discuss the relationship between the area of a region and the definite integral. *​
melisa1 [442]

Answer:

The integral symbol in the previous definition should look familiar. We have seen similar notation in the chapter on Applications of Derivatives, where we used the indefinite integral symbol (without the a and b above and below) to represent an antiderivative. Although the notation for indefinite integrals may look similar to the notation for a definite integral, they are not the same. A definite integral is a number. An indefinite integral is a family of functions. Later in this chapter we examine how these concepts are related. However, close attention should always be paid to notation so we know whether we’re working with a definite integral or an indefinite integral.

Integral notation goes back to the late seventeenth century and is one of the contributions of Gottfried Wilhelm Leibniz, who is often considered to be the codiscoverer of calculus, along with Isaac Newton. The integration symbol ∫ is an elongated S, suggesting sigma or summation. On a definite integral, above and below the summation symbol are the boundaries of the interval, \left[a,b\right]. The numbers a and b are x-values and are called the limits of integration; specifically, a is the lower limit and b is the upper limit. To clarify, we are using the word limit in two different ways in the context of the definite integral. First, we talk about the limit of a sum as n\to \infty . Second, the boundaries of the region are called the limits of integration.

We call the function f(x) the integrand, and the dx indicates that f(x) is a function with respect to x, called the variable of integration. Note that, like the index in a sum, the variable of integration is a dummy variable, and has no impact on the computation of the integral.

his leads to the following theorem, which we state without proof.

Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5.
ale4655 [162]
Parallel lines should have the same slope. In the equation of the line, Ax + By + C = 0. The slope of the line is calculated by dividing the negative of A by B. The slope of the line given is 3. Below, I listed the slopes.

(1) m = -6/2 = -3
(2) m = 3/1 = 3
(3) m = 9/3 = 3
(4) m = -1/3 

Thus, the answers are the 2nd and 3rd choices.
