Answers
The minimum sample size needed to estimate the proportion of U.S. adults supporting the proposed amendment with a 95% c
To determine the sample size needed for estimating the proportion of U.S. adults supporting the proposed amendment to the constitution with a confidence level of 95% and a margin of error of 4%, we can use the formula:
n = (Z^2 * p * (1 - p)) / (E^2)
Where:
n = sample size
Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to a Z-score of approximately 1.96)
p = estimated proportion (since we don't have an estimate, we can assume p = 0.5, which provides the maximum sample size required)
E = margin of error (0.04 in this case)
Plugging in the values, we get:
n = (1.96^2 * 0.5 * (1 - 0.5)) / (0.04^2)
n = 600.25 / 0.0016
n ≈ 37515.625

Ignacio chooses a plant at random that does not have a white bloom. What is the probability of the complement of the event? Express your answer as a fraction in simplest form
Answers
The probability of the complement of the event of Ignacio chooses a plant at random that does not have a white bloom is 0.7692.
The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more probable it is that the event will take place.
Probability is a way to gauge how likely something is to happen. Several things are difficult to forecast with absolute confidence. With it, we can only make predictions about the likelihood of an event happening, or how likely it is.
The probability that Ignacio chooses the plant which have white bloom in it is,
P = number of white bloom / total number of flowers
P = 21 / 91
So the probability that the chosen flower is not white is,
1 - P = 1 - 21/91 = 70/91 = 0.7692.
Therefore, the probability of not choosing white is 0.7692.

If Argyle says that she has collected data that only tell her whether the cases are the same or different, one can accurately say that she has collected data on the nominal level.
What is the nominal level of measurement?The nominal level of measurement is the least strict type of data measurement in which the measurements or observations are grouped into distinct categories without a specific order or value structure. At this stage of measurement, variables are defined as categorical because the groups and categories can only be counted, which is usually done using frequencies and proportions.
The nominal level of measurement can take the form of either binary or multichotomous. Binary variables have only two groups, while multichotomous variables have more than two groups. Variables that are frequently used in this level of measurement include gender, race, or political affiliations.

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 30 meses de plazo.calcula la cuota fija mensual que se pagará seda empresa cobra una tasa de interés simple del 12% semestralmente
Answers
Responder:
2560
Explicación paso a paso:
Dado lo siguiente:
Precio del automóvil = 60000
Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000
Saldo = (60000 - 12000) = 48000
La empresa cobra un interés simple del 12% cada 6 meses
Periodo de pago = 30 meses / 6 = 5 periodos
Interés simple: p * r * t
= 48000 * 0,12 * 5 = 28800
Por lo tanto, monto total a reembolsar, incluidos los intereses:
Balance + 28800; 48000 + 28800 = 76800
El reembolso mensual es fijo;
Por lo tanto,
76800/30 = 2560

The unit of measurement used is A. Standard deviation is the unit of measurement used to describe how far a set of values are from the mean.
What is standard deviation ?The degree of variation of data from the average, or mean, is gauged by the standard deviation. It provides us with information on the average amount by which each data point diverges from the mean.
A lesser standard deviation suggests that the data points gather closely around the mean, whereas a greater standard deviation signifies that the data points are further dispersed. To standardize a value, we subtract the mean from the value and then divide by the standard deviation.

Deondra has $12 to spend on a mixture of green and red grapes. What equation can she use to graph a line showing the different amounts of green and red grapes she can buy for $12?
Answers
Answer:
It depends on the cost of grapes.
Step-by-step explanation:
Half of 12 is 6, so if each pack of grapes cost 6 or less, she can buy a pack of green and red grapes.
The equation that Deondra can use to graph the line showing different amounts of green and red grapes she can buy for $12 is :
ax + by = 12
Let the number of green grapes be a
Let the cost of one green grape be x
Let the number of red grapes be b
Let the cost of one red grape be y
The total cost of green and red grapes = $12
The equation representing the illustration will be of the form:
(Number of green grapes)(Cost of 1 green grape) +
(Number of red grapes)(cost of 1 red grape) = Total cost
The equation that Deondra can use to graph the line showing different amounts of green and red grapes she can buy for $12 is therefore:
ax + by = 12

Answers
Since the matrix A is singular (determinant = 0), it means the system of equations has no unique solution. Therefore, we cannot find the exact amounts given to each of the siblings without additional information or constraints.
What is the given data?Given:
1. Ama, Efua, and Baaba were given amounts x, y, and z, respectively.
2. Ama negotiates an interest rate of 5% per annum.
3. Efua invests in an account with an interest rate of 10% per annum.
4. Baaba invests in an account with an interest rate of 8% per annum.
5. At the end of the year, the total interest earned is ¢800.
Now, let's solve the problem step by step:
(a) Write down the three linear equations:
1. Ama's investment: x * 0.05
2. Efua's investment: y * 0.10
3. Baaba's investment: z * 0.08
We also know that the total interest earned is ¢800, so we can write another equation:
4. Ama's investment + Efua's investment + Baaba's investment = 800
(b) Represent the system of equations in matrix form AX = B:
The matrix form will be:
[0.05 0 0] [x] [0]
[0 0.10 0] * [y] = [0]
[0 0 0.08] [z] [0]
[1 1 1] [ ] [800]
(c) Find the determinant of the matrix A:
To find the determinant of matrix A, we calculate:
det(A) = (0.05 * 0.10 * 0.08) = 0.0004
(e) Find the amount of money given to each of the 3 siblings:
Using matrix operations, we can solve the system of equations by multiplying the inverse of matrix A with matrix B:
X = A^(-1) * B
However, since the matrix A is singular (determinant = 0), it means the system of equations has no unique solution. Therefore, we cannot find the exact amounts given to each of the siblings without additional information or constraints.

13, Find the exact value of ¹³√16 – (x− 9)² dx . ¹³√16-(x −9)² dx= +
Answers
The value of the given integral is 152/3.
The given integral is,¹³√16 - (x - 9)² dx
Let us substitute (x - 9) = 4u.
Then x = 4u + 9
dx/dt = 4du/dt
So, the given integral becomes:
∫(¹³√16 - 16u²)(4 du/ dt) du
On solving this, we get,
∫¹³√16 × 4du - ∫16u² × 4du
Now, as there are no limits of the integral, we take the limits as 0 to 1 in the above expression.
∫¹³√16 × 4du - ∫16u² × 4du[∵ (x - 9) = 4u]
Now, substituting the limits in the integral we get,
∫¹³√16 × 4du - ∫16u² × 4du [u = 0 to u = 1]
= [(¹³√16) × (4u)]0¹ - ∫0¹ 16u² × 4du
Now, substituting the values of the limits we get,
(¹³√16) × 4 - ∫0¹ 16u² × 4du
= 52 - (4/3)[u³]0¹ [∵ 16 × 4/3 = 64/3]
Thus, the value of the given integral is:
52 - (4/3)[u³]0¹ = 52 - (4/3) × 1³
= 52 - (4/3)
= 156/3 - 4/3
= 152/3
Therefore, the value of the given integral is 152/3.

Un avión de pasajeros hizo un viaje de ida y vuelta a Las Vegas. En el viaje de ida voló a 432 mph y en el viaje de regreso a 480 mph. ¿Cuánto tiempo tomó el viaje allí si el viaje de regreso tomó nueve horas?
Answers
The time taken for the trip if the return trip was 9 hours is 17 hours.
How to calculate the time?The outward journey used 432 mph. The return journey was 480 mph and this was for 9 hours.
Let the time taken for the initial trip be x. This will be:
x/9 = 432 / 48
Cross multiply
480x = 432 × 9
x = (432 × 9) / 480
x = 8
Therefore, the initial trip was 8 hours.
The time taken for the whole trip will be:
= Outward trip + Return trip
= 8 hours + 9 hours
= 17 hours.
