How many square centimeters are in an area of 11.6inch
2
? Express your answer numerically in square centimeters.
The area of 11.6 square inches is equivalent to approximately 74.84 square centimeters.
To convert square inches to square centimeters, we need to use the conversion factor 1 inch = 2.54 centimeters. Since we are dealing with areas, we need to square this conversion factor as well.
Convert inches to centimeters:
11.6 inches * 2.54 centimeters/inch = 29.464 centimeters
Square the conversion factor:
(2.54 centimeters/inch) * (2.54 centimeters/inch) = 6.4516 square centimeters/square inch
Calculate the area in square centimeters:
29.464 centimeters * 6.4516 square centimeters/square inch = 74.84 square centimeters.
Rounding this value to two decimal places, the area of 11.6 square inches is approximately 190.29 square centimeters.

Determine whether the underlined value is a parameter or a statistic.
Following the election, 18 % of the governors of all 50 areas of a country were female.
Is the value a parameter or a statistic?
The given numerical value is a Statistic.
Parameters are numeric values that characterize the population as a whole. A statistic is a number that describes the characteristics of a sample.
For example, median income in the United States is a demographic parameter. Conversely, the median income for the US sample is a sample statistic. Both values represent median income, but one is a parameter to the statistic. Easy to remember parameters and stats! Both are summary values that describe the group, and have a convenient mnemonic device to remind you which group is being described. Notice their initials.
Parameter = Population
Statistics = Sample
A population is the entire group of people, things, animals, trades, etc. that are being studied. A sample is part of a population.
Following the election, 18 % of the governors of all 50 areas of a country were female.

You recently joined a gym. You had to pay a joining fee of $40, and you will pay $20 per month to maintain the membership. What is the one-time charge? What does it represent in slope-intercept form? What is the recurring charge? What does it represent in slope-intercept form?
The one-time charge for joining the gym was $40. This can be represented in slope-intercept form as y = $40, where y is the total cost of joining the gym.
The recurring charge for maintaining the membership is $20 per month. This can be represented in slope-intercept form as y = $20x, where y is the total cost of maintaining the membership and x is the number of months the membership is maintained.
In both cases, the slope represents the cost per unit (either a one-time charge or a recurring charge per month), and the y-intercept represents the total cost when the number of units is 0 (either the one-time charge for joining the gym or the cost of maintaining the membership for 0 months).

We have to find the amount of money raised by all three schools.
The first school: EON, raised $286.00
The second school: Hackett raised $192.84
The third school: Myers raised $113.25 more than Hackett
To calculate the amount that the third school raised, we add $113.25 to the amount that the second school raised $192.84:
\(192.84+113.25=306.09\)Myers raised $306.09
Finally, we add the money that the three schools raised to find the total:
\(286.00192.84+306.09=784.93\)The total amount of money raised was $784.93
Answer:

Step-by-step explanation:
A dry cleaner uses exponential smoothing to forecast equipment usage at its main plant. August usage was forecasted to be 88 percent of capacity; actual usage was 89.6 percent of capacity. A smoothing constant of 0.1 is used.
The forecasted equipment usage for September, based on exponential smoothing with a smoothing constant of 0.1, is 88.16 percent of capacity.
To apply exponential smoothing and determine the forecasted equipment usage at the main plant, we can use the following formula:
F(t) = α * A(t) + (1 - α) * F(t-1)
Where:
F(t) is the forecasted value at time t,
A(t) is the actual value at time t,
F(t-1) is the forecasted value at time (t-1),
α is the smoothing constant.
Given that the forecasted usage for August was 88 percent and the actual usage was 89.6 percent, and the smoothing constant α is 0.1, we can calculate the forecasted value for September.
Let's assume F(t-1) represents the forecasted usage for August, which is 88 percent. Then, plugging in the values into the exponential smoothing formula, we have:
F(t) = 0.1 * 89.6 + (1 - 0.1) * 88
F(t) = 8.96 + 0.9 * 88
F(t) = 8.96 + 79.2
F(t) = 88.16

what are the relationships of numerator and denominator coefficients with r, l, and c values of a circuit?
The relationships between the numerator and denominator coefficients of a circuit and the values of resistance (R), inductance (L), and capacitance (C) depend on the specific circuit configuration and the transfer function associated with it.
In general, the numerator coefficients of the transfer function represent the output variables of the circuit, while the denominator coefficients represent the input variables. The coefficients are determined by the circuit elements (R, L, C) and their interconnections.
For example, in a simple RC circuit (resistor and capacitor), the transfer function can be written as a ratio of polynomials in the Laplace domain. The denominator coefficients correspond to the characteristic equation of the circuit and involve the resistance and capacitance values. The numerator coefficients may be related to the initial conditions or external inputs.

In a triangle the measurements of the angles are x°, ( x + 6)°, (2x + 10)°, and the sum of the three angles of a triangle is 180. What is the measurement of the largest angle in degrees?
Answer:
largest angle = 92°
Step-by-step explanation:
Since the measurement of the angles are;
x°, ( x + 6)°, (2x + 10)°
And we know that sum of angles in a triangle is 180. Thus;
x + (x + 6) + (2x + 10) = 180
x + x + 6 + 2x + 10 = 180
4x + 16 = 180
4x = 180 - 16
4x = 164
x = 164/4
x = 41°
The other two angles will be;
(41 + 6)° and (2(41) + 10)°
Which gives;
47° and 92°
So,largest angle = 92°

Answer:
We have parallel lines intersected by a transversal.
Corresponding angles are congruent:
5q + 3 = 3q + 11
2q = 8, so q = 4
Alternate interior angles are congruent:
3r - 4 = 6r - 19
3r = 15, so r = 5
Consecutive interior angles are supplementary:
4s + s + 90 = 180
5s = 90, so s = 18
Supplementary angles:
2t + 20 = 4t + 10
2t = 10, so t = 5
Let f(x)=−5x3+7.5x+2. In this problem you will estimate f′(−2) by computing the average rate of change of f(x) over a small interval. Round your answers to three decimal places. 1. First choose the interval of length .1 with −2 being the left endpoint of the interval. Then f′(−2)≈ 2. Now let the interval have length .01. Then f′(−2)≈ 3. Finally let the interval have length .001 Then f′(−2)≈
The estimated value of f'(−2) remains approximately 2.250 regardless of the interval length chosen (0.1, 0.01, or 0.001).
To estimate f'(−2) by computing the average rate of change of f(x) over small intervals, we can use the formula:
f'(−2) ≈ (f(−2 + h) - f(−2)) / h,
where h represents the length of the interval.
For an interval length of 0.1, with −2 as the left endpoint:
h = 0.1
f'(−2) ≈ (f(−2 + 0.1) - f(−2)) / 0.1
Substituting the values into the formula and rounding to three decimal places, we have:
f'(−2) ≈ (-5(-2 + 0.1)^3 + 7.5(-2 + 0.1) + 2 - (-5(-2)^3 + 7.5(-2) + 2)) / 0.1
f'(−2) ≈ 2.250
For an interval length of 0.01:
h = 0.01
f'(−2) ≈ (f(−2 + 0.01) - f(−2)) / 0.01
Substituting the values into the formula and rounding to three decimal places, we have:
f'(−2) ≈ (-5(-2 + 0.01)^3 + 7.5(-2 + 0.01) + 2 - (-5(-2)^3 + 7.5(-2) + 2)) / 0.01
f'(−2) ≈ 2.250
For an interval length of 0.001:
h = 0.001
f'(−2) ≈ (f(−2 + 0.001) - f(−2)) / 0.001
Substituting the values into the formula and rounding to three decimal places, we have:
f'(−2) ≈ (-5(-2 + 0.001)^3 + 7.5(-2 + 0.001) + 2 - (-5(-2)^3 + 7.5(-2) + 2)) / 0.001

In a binomial situation, n=18 and π=0.60. Determine the expected
value
The expected value in a binomial situation with n = 18 and π = 0.60 is E(X) = np = 18 * 0.60 = 10.8.
In a binomial situation, the expected value, denoted as E(X), represents the average or mean outcome of a random variable X. It is calculated by multiplying the number of trials, denoted as n, by the probability of success for each trial, denoted as π.
In this case, we are given n = 18 and π = 0.60. To find the expected value, we multiply the number of trials, 18, by the probability of success, 0.60.
n = 18 (number of trials)
π = 0.60 (probability of success for each trial)
To find the expected value:
E(X) = np
Substitute the given values:
E(X) = 18 * 0.60
