Participants in a study on the effects of viagra are assigned to groups, the independent variable is The viagra.

In an algebraic equation, an independent variable is a variable whose values are not impacted by changes. It is claimed that the value of y is a function of the value of the independent variable (x), also known as the x value, and the value of y is known as the dependent variable, in an algebraic equation with two variables (x and y), if any value of x is related to any other value of y.

The alphabetic letter that conveys a numerical value or a number is known as a variable in mathematics. In algebraic equations, a variable is used to represent an unknowable quantity.

For these variables, any alphabet from a to z may be used. Most frequently, the variables "a," "b," "c," "x," "y," and "z" are utilised in equations.

Answer:

C. 32

Step-by-step explanation:

The shipment for 100 parts is received by a manufacturer. Shipment will be rejected if more than 5 parts are defective. The manufacturer selects a sample and based on that selected sample he accepts or rejects the whole shipment. The minimum size of the sample should be 32 based on the probability of less than 0.1 and then  decision should be made whether to accept or reject the shipment. If no defective part is found in the sample, shipment should be accepted.

Blake should invest $6,000 at 4% interest and the remaining $5,000 (11000 - 6000) at 5% interest to earn exactly $490 at the end of 1 year.

Let's denote the amount of money Blake invests at 4% interest as "x" (in dollars) and the amount he invests at 5% interest as "11000 - x" (since the total investment is $11,000).

To earn interest, we can use the formula: Interest = Principal × Rate × Time

For the 4% interest account, the interest earned is:

0.04x × 1 (1 year) = 0.04x

For the 5% interest account, the interest earned is:

0.05(11000 - x) × 1 (1 year) = 550 - 0.05x

According to the problem, the total interest earned is $490. Therefore, we can set up the equation:

0.04x + (550 - 0.05x) = 490

Simplifying the equation:

0.04x + 550 - 0.05x = 490

-0.01x + 550 = 490

-0.01x = -60

x = 6000

Blake should invest $6,000 at 4% interest and the remaining $5,000 (11000 - 6000) at 5% interest to earn exactly $490 at the end of 1 year.

The function 2x³ + x + 0.3y = 2 has a negative value at x = -4, a relative maximum at x = -1.5, and changes concavity at x = -2.75.
The function y = 3x² - 3x + 2 has a positive derivative at x = 0, is concave down over the interval (-∞, 0.25), and is increasing over the intervals (1.5, ∞) and (-∞, -1).

For the function 2x³ + x + 0.3y = 2, we are given specific values of x where certain conditions are met. At x = -4, the function has a negative value, indicating that the y-coordinate is less than zero at that point. At x = -1.5, the function has a relative maximum, meaning that the function reaches its highest point in the vicinity of that x-value. Finally, at x = -2.75, the function changes concavity, indicating a transition between being concave up and concave down.
Examining the function y = 3x² - 3x + 2, we consider different properties. The derivative of the function represents its rate of change. If the derivative is positive at a particular x-value, it indicates that the function is increasing at that point. In this case, the derivative is positive at x = 0.
Concavity refers to the shape of the graph. If a function is concave down, it curves downward like a frown. Over the interval (-∞, 0.25), the function y = 3x² - 3x + 2 is concave down.
Lastly, we examine the intervals where the function is increasing. An increasing function has a positive slope. From the given information, we determine that the function is increasing over the intervals (1.5, ∞) and (-∞, -1).
In summary, the function 2x³ + x + 0.3y = 2 exhibits specific characteristics at given x-values, while the function y = 3x² - 3x + 2 demonstrates positive derivative, concave down behavior over a specific interval, and increasing trends in certain intervals.

The possible results from the simulation described from the dotplots is with most of the dots at 1 and 2.

The dot plot that best represents the possible results from the simulation described would be one where the majority of the dots are clustered around 1-2 canceled flights, with some dots representing 0 canceled flights and a few dots representing 3 or more canceled flights. This is because with a probability of success (a canceled flight) of 0.015, the expected number of canceled flights in a sample of 100 would be 1.5 (0.015 x 100), and the distribution of the number of canceled flights from the 50 trials would likely be approximately normal with a mean of 1.5 and a standard deviation of 0.35 (the standard deviation for a binomial distribution with n = 100 and p = 0.015).

Answer:

199 steel rods

Step-by-step explanation:

From that attached diagram, we are told that a truss is made by attaching 1 foot long steel rods together.

In order to make an additional length for the Truss, we use this algebraic expression formula:

Number of steel rods = 4x - 1

Where x = Number of feet

Where x = 1 feet

4(1) - 1 = 4 - 1 = 3 steel rods

From the above question, we are asked to determine number of steel rods in a 50 feet long truss.

Applying the Formula

4x - 1 = Number of steel rods

4(50) - 1

200 - 1 = 199 steel rods.

Therefore, 199 steel rods are in a truss 50 feet long overall

The value of the investment at the end of the year, when A^(7),000 is invested at a 12% per annum compound interest, compounded monthly

To find the value of the investment at the end of the year, compounded monthly at a rate of 12%, we can use the formula for compound interest:

A = P *\((1 + r/n)^(nt)\)

Where:

A is the final amount (value of the investment at the end of the year),

P is the principal amount (A^(7),000 in this case),

r is the annual interest rate (12% or 0.12),

n is the number of times the interest is compounded per year (12, as it is compounded monthly), and

t is the time in years (1 year).

Plugging in the values, we get:

A =\(A^(7,000 )* (1 + 0.12/12)^(12*1)\)

= A^(7),000 * (1 + 0.01)^(12)

= A^(7),000 * (1.01)^(12)

= A^(7),000 * 1.12682503013

Therefore, the value of the investment at the end of the year, when \(A^(7,000)\)is invested at a 12% per annum compound interest, compounded monthly, is approximately [insert calculated value].

It is not possible to construct a triangle whose sides are 9 cm 7 cm and 17 cm because the sum of two sides(9 cm and 7 cm) are smaller than third sides(17 cm).

In the given question, we have to check that it is possible to construct a triangle whose sides are 9 cm 7 cm and 17 cm.

To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always greater than the third side.

To check this we firstly add the 9 and 7

9 + 7 < 17

16 < 17

Now we add 17 and 7

17 + 7 > 9

24 > 9

Now we add 9 and 17

9 + 17 > 7

Trying to factor by splitting the middle term

2.1     Factoring  4a2-2a+9

The first term is,  4a2  its coefficient is  4 .

The middle term is,  -2a  its coefficient is  -2 .

The last term, "the constant", is  +9

Step-1 : Multiply the coefficient of the first term by the constant   4 • 9 = 36

The probability that a standard normal variable is less than or equal to 0.25 is approximately 0.2957. This can be found by looking up the value of 0.25 in the standard normal table.

The standard normal table is a table that gives the probability that a standard normal distribution will be less than or equal to a certain value. The values in the table are expressed as percentages. To find the probability that a standard normal variable is less than or equal to 0.25, we look up the value of 0.25 in the table and find the corresponding percentage.

It will take Vincent 24 number of days to build the cubby house by himself.

Let's assume that Vincent can build the cubby house alone in h days.

From the given information, we know that Nadia takes 12 days to build the cubby house, and when Nadia and Vincent work together, they can finish it in 8 days.

We can use the concept of "work done" to solve this problem. The amount of work done is inversely proportional to the number of days taken.

Nadia's work rate is 1/12 of the cubby house per day, while the combined work rate of Nadia and Vincent is 1/8 of the cubby house per day.

When Nadia and Vincent work together, their combined work rate is the sum of their individual work rates:

1/8 = 1/12 + 1/h

To solve for h, we can rearrange the equation:

1/h = 1/8 - 1/12

1/h = (3 - 2) / 24

1/h = 1/24

Taking the reciprocal of both sides, we find:
