Answers
Mrs. Rosenblatt's class has an average grade of 87. After realizing she left out Joe's score of 65, the new mean will be lower than 87.
Explanation:
To find the new mean, we need to calculate the sum of all the grades in the class, including Joe's score of 65, and divide it by the total number of students in the class. Let's assume there are n students in the class.
The sum of all the grades in the class, including Joe's score, will be (87 * n) + 65, since the average grade before Joe's score was added was 87. Therefore, the new mean will be:
[(87 * n) + 65] / (n + 1)
Expanding this expression, we get:
(87n + 65) / (n + 1)
Simplifying this expression, we get:
(87n / (n + 1)) + (65 / (n + 1))
Since n is a positive integer, the value of (87n / (n + 1)) will be slightly less than 87. Therefore, the new mean will be slightly less than 87, reflecting the lower score added to the class average.

C)Si en una fila hay 34 flores ¿a qué fila pertenece?
Answers
Answer:
a) Para \(i = 4\), hay 13 flores en la fila 4.
b) Para \(i = 7\), hay 22 flores en la fila 7.
c) La fila 11 tiene 34 flores.
Step-by-step explanation:
De acuerdo con el enunciado, cada fila tiene tres flores más que la fila inmediatamente anterior, significando que se puede determinar el número de flores de cada fila mediante una serie aritmética:
\(n = 4+3\cdot (i-1)\), \(i \ge 1\) (1)
Donde:
\(i\) - Índice de la fila de flores.
\(n\) - Número de flores del índice de la fila de flores.
a) Para \(i = 4\), hay 13 flores en la fila 4.
b) Para \(i = 7\), hay 22 flores en la fila 7.
c) Si \(n = 34\), entonces el índice de la fila es:
\(i=1+\frac{n-4}{3}\)
\(i = 11\)
La fila 11 tiene 34 flores.

This is a translation of 2 units to the left and 5 units up, so the correct option is the first one.,
Which is the translation applied?Remember that a vertical translation of N units is:
g(x) = f(x) + N
if N < 0 the translation is down.
if N > 0 the translation is up.
And a horizontal translation of N units is:
g(x) = f(x + N)
If N > 0 the translation is to the right.
if N < 0 the translation is to the left.
Here we have the transformation:
f(x) = x²
g(x) = (x + 2)² + 5

When approximating Sºf(x)dx using Romberg integration, R33 gives an approximation of order: h10 h8 h4 h6 Romberg integration for approximating S. f(x)dx gives R21 = 7 and R22 = 7.21 then f(1) = 4.01 3.815 1.68 -0.5
Answers
Using Romberg integration, f(1) = 4.01.
Based on the given information, we can deduce the order of approximation for \(R_{33}\) in Romberg integration as h10, h8, h4, h6. Additionally, we are given the values \(R_{21} = 7\) and \(R_{22} = 7.21\).
Romberg integration typically follows the pattern R(k, m), where k represents the number of iterations and m denotes the number of function evaluations per iteration.
From \(R_{21} = 7\), we can determine that the approximation achieved after two iterations is 7.
From \(R_{22} = 7.21\), we can conclude that the approximation achieved after two iterations is 7.21.
Since \(R_{21}\) and \(R_{22}\) represent the same number of iterations (k = 2), we can directly compare the results of these two approximations.
Therefore, the final answer is: f(1) = 4.01.

In interpreting effect size, what is the meaning of effect size at 0.3?
a. small effect size
b. medium effect size
c. large effect size
d. weak effect size
Answers
In interpreting effect size, the meaning of effect size at 0.3 is small effect size. So, the correct answer is A).
In interpreting effect size, an effect size of 0.3 is typically considered to be a small effect size. This means that there is a small but still measurable difference or relationship between two variables.
The interpretation of effect size can vary depending on the context and the discipline in which it is being used, but as a general rule, effect sizes of 0.2 or smaller are considered small, effect sizes of 0.5 are considered medium, and effect sizes of 0.8 or larger are considered large. Therefore, an effect size of 0.3 falls in the small effect size range. So, the correct option is A).

Surface area = 6(Side)²
If the length of the each side of the box is = 3 feet

Show that .2πT 0 1 2+ cos 0 -do = 2π √√3
Answers
To show that the integral of (0.2π/T) + cos(t) dt from 0 to 2π equals 2π√(√3), we can evaluate the integral and simplify the expression.
The integral represents the area under the curve of the function (0.2π/T) + cos(t) from t = 0 to t = 2π. By applying integration techniques and simplifying, we can verify that the integral equals 2π√(√3).
Let's evaluate the integral ∫[(0.2π/T) + cos(t)] dt from 0 to 2π. The antiderivative of 0.2π/T is (0.2π/T)t, and the antiderivative of cos(t) is sin(t). Applying the fundamental theorem of calculus, we have:
∫[(0.2π/T) + cos(t)] dt = (0.2π/T)t + sin(t) │ from 0 to 2π.
Substituting the limits, we get:
[(0.2π/T)(2π) + sin(2π)] - [(0.2π/T)(0) + sin(0)].
Simplifying, we have:
(0.4π²/T) + 0 - 0 - 0 = (0.4π²/T).
To show that (0.4π²/T) equals 2π√(√3), we need to equate it to 2π√(√3) and solve for T:
(0.4π²/T) = 2π√(√3).
Dividing both sides by 2π, we get:
(0.4π²/T) = √(√3).
Squaring both sides and simplifying, we have:
(0.4π²/T)² = (√(√3))²,
(0.4π²)² / T² = (√3),
0.16π⁴ / T² = √3.
Taking the square root of both sides and rearranging, we obtain:
√(0.16π⁴ / (√3)) = T,
2π √(√3) = T.
Therefore, we have shown that the integral of (0.2π/T) + cos(t) dt from 0 to 2π equals 2π√(√3)

We want to find the value of x, which is the hypotenuse of the triangle on the image.
We will see that the value of x is 5.77 units.
How to find the value of x?On the figure we can see a right triangle, we want to find the value of x, which is the hypotenuse of this triangle.
To do so, we can use the trigonometric relation:
cos(θ) = (adjacent cathetus)/(hypotenuse)
Where θ is an internal angle of the triangle, and the adjacent cathetus is the cathetus that forms the angle.
Here we can use θ = 30°, and the adjacent cathetus is the one that has a measure of 5 units, then the value of x is given by the equation:
cos(30°) = 5/x
Solving that for x we will get:
x = 5/cos(30°) = 5.77
The hypotenuse measures 5.77 units.
