There are green grapes and black grapes in the ratio 3:4 if there are 24 green grapes how many black grapes are there?

Answer:

Hi! The trouble here is converting the minutes and seconds of the angles. Complimentary angles total 90 degrees. There are 60 minutes in one degree, so you actually have 89 degrees and 60 minutes. There are 60 seconds in a minute, so now you have 89 degrees, 59 minutes, and 60 seconds. Now you can subtract:

89-27 = 62 degrees

59-35 = 24 minutes

60-15 = 45 seconds

So the compliment is 62024'45"

The same logic happens for the supplement except you have 179 degrees 59 minutes and 60 seconds.

179-27 = 152

59-35 = 24

60-15 = 45

So the supplement is 152024'45"

0.005 ≈ 1 (1 is the nearest whole number)

Hope this helps!

The number 5 divided by 1,000 is approximately 0 when rounded to the nearest whole number.

To divide 5 by 1,000, we simply perform the division:

5 ÷ 1,000 = 0.005

Now, to round the result to the nearest whole number, we examine the first decimal place. Since it is less than 5, we round down to the nearest whole number.

Thus, the rounded result is 0.

Rounding is a process used to simplify numbers to a certain level of precision. When rounding to the nearest whole number, we look at the digit to the right of the decimal point (the first decimal place). If this digit is 5 or greater, we round up to the next whole number. If it is less than 5, we round down to the current whole number.

In this case, 0.005 is less than 0.5, so we round down to 0.

The dependent variable in this study is the test scores of the subjects. In the study described, the researcher is interested in examining the effect of listening to classical music while studying on subsequent test performance.

The dependent variable is the test scores that the subjects receive after studying, which is the outcome that the researcher is interested in measuring and comparing between the two groups of subjects (those who listened to classical music and those who studied in silence).

By randomly assigning subjects to either the classical music or silence condition, the researcher can control for potential confounding variables (such as prior knowledge of the material or motivation to perform well on the test) that might otherwise affect the results. This allows the researcher to more confidently attribute any observed differences in test scores to the manipulation of the independent variable (listening to classical music) and draw conclusions about its effect on test performance.

The probability that X=4 is (c) 0.1029.The probability that X=4 in the given geometric distribution is 0.1029, which corresponds to option (c).

In a geometric distribution, the probability of success (p) is given as 0.3 and the probability of failure (q) is 0.7. The probability mass function (PMF) of a geometric distribution is given by P(X=k) = (1-p)^(k-1) * p, where k is the number of trials.

In this case, we want to find P(X=4). Substituting the given values into the PMF formula, we have P(X=4) = (1-0.3)^(4-1) * 0.3 = 0.7^3 * 0.3 = 0.343 * 0.3 = 0.1029.

An equation is formed of two equal expressions. The equation of the ellipse is,

⇒ [(x-6)²/49] + [(x-2)²/9] = 1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As it can be seen that the centre of the ellipse is at (6,2). Also, the major radius is equal to 7 units, while the minor radius is equal to 3 units. The general equation of the ellipse is given as,

(x - h)²/a² + (y - k)²/b² = 1

(x - 6)²/7² + (y - 2)²/3² = 1

[(x-6)²/49] + [(x-2)²/9] = 1.

The graph of the given function for two periods is shown below: Graph of f(x) = -3sin(x - 3π/4) for two periods.

The given function is f(x) = -3sin(x - 3π/4).

We have to determine its amplitude and period and then graph it for two periods

Amplitude: The amplitude of the given function is 3.

Since there is a negative sign outside the sine function, the amplitude of the function becomes negative.

Period: The period of the given function is 2π/1 or 2π. This is because the coefficient of x in the function is 1.

The period is given by 2π/b, where b is the coefficient of x in the function.

To graph the function for two periods, we need to graph the function for one period and then replicate the graph for another period.

We want to find the dimensions of the poster such that the area of the whole poster is minimized .These are: Length = 325.2cm and

Width = 17cm

We can assume that the poster is a rectangle, and we know that a rectangle of length L and width W has an area:

A = L*W

Here we do know that the top and bottom margins are 9 cm each.

The side margins are 6cm each.

Then the measures of the printed areas are:

W' = W - 2*6cm = W - 12cm

L' = L - 2*9cm = L - 18cm

And we know that the area of the printed part is 1536 cm^2, then we can write:

A'  = (W - 12cm)*( L - 18cm) = 864 cm^2

      W*L - 12cm*L - 18cm*W + 216cm^2 = 1536 cm^2

      W*L = 12cm*L + 18cm*W + 1320cm^2

And W*L is equal to the area, so what we need to minimize is:

A =  12cm*L + 18cm*W + 1320cm^2

Here we can see that the dependence of the area is larger on W than on L, so what we need to minimize is W.

We will take the smallest value of W such that the given margins are allowed.

That value would be such that:

W - 12cm > 0

W > 12cm

this could (and to be strict, should) be something like 16.0001cm, but let's use 17cm just to use whole numbers, we will get:

W = 17cm

Then to get the length we solve:

W*L = 12cm*L + 18cm*W + 1320cm^2

17cm*L = 12cm*L + 18cm*17cm + 1320cm^2

5cm*L = 1560cm^2

Answer:

Oblique rectangular prism

The value of the right Riemann sum approximation for integral ∫₀² f(x) dx is (c) 60.

The right Riemann sum approximation is obtained by dividing the interval [0, 2] into four subintervals of equal length and evaluating the function at the right endpoints of each subinterval. In this case, each subinterval has a length of (2-0)/4 = 0.5. The right endpoints of the subintervals are 0.5, 1.0, 1.5, and 2.0.

To calculate the right Riemann sum, we evaluate the function at these right endpoints and sum up the values multiplied by the subinterval length.

f(0.5) = \(9^{0.5\) = 3

f(1) = 9¹ = 9

f(1.5) = \(9^{1.5\) = 27

f(2) = 9² = 27

The right Riemann sum is then

= (0.5 * f(0.5)) + (0.5 * f(1.0)) + (0.5 * f(1.5)) + (0.5 * f(2.0))

= 0.5 * (3 + 9 + 27 + 81)

= 60.

Therefore, the value of the right Riemann sum approximation for ∫2 to 0 f(x) dx is 60, which corresponds to option (c).

As a quarter of 100, a number can be expressed as a percentage. It is frequently used to describe distinctions or express changes in numbers. The symbol for percentages is %, and they are frequently utilized to describe ratios, rates, and certain other numerical connections. An 80 percent score on a test, for instance, indicates that the student correctly answered 80 of the 100 questions. Similar to this, if a retailer were offering a 20% discount on a $100 item, the sale price would be $80.

given

With P = 10000, r = 0.08 (8% stated as a decimal), n = 12 (compound monthly), and t to be found when A = 20000, the situation is as follows.

When these values are added to the formula, we obtain:

\(20000 = 10000(1 + 0.08/12)^(12t) (12t)\)

By multiplying both sides by 1000, we obtain:

\(2 = (1 + 0.08/12)^(12t) (12t)\)

When we take the natural logarithm of both sides, we obtain:

ln(2) = 12t ln(1 + 0.08/12)

When we multiply both sides by 12 ln(1 + 0.08/12), we obtain:

t = ln(2) / (12 ln(1 + 0.08/12))

Using the Lagrange method, the optimal choice is therefore (x1, x2) = (20/9, 4/3).

The optimal choice when pı = 3, P2 = 5 and I = 20 and utility is u(x1, x2) = min{2x1, x2} can be found using the Lagrange method .Lagrange method: This method involves formulating a function (the Lagrange function) which should be optimized with constraints, i.e. the optimal result should be produced while adhering to the constraints provided. The Lagrange function is given by: L(x1, x2, λ) = u(x1, x2) - λ(I - p1x1 - p2x2)

Where L is the Lagrange function, λ is the Lagrange multiplier, I is the budget, p1 is the price of good 1, p2 is the price of good 2.The optimal choice can be determined by the partial derivatives of L with respect to x1, x2, and λ, and setting them to zero to get the critical points. Then, the second partial derivative test is used to determine if the critical points are maxima, minima, or saddle points. The critical points of the Lagrange function L are:

∂L/∂x1 = 2λ - 2p1 = 0 ∂L/∂x2 = λ - p2 = 0 ∂L/∂λ = I - p1x1 - p2x2 = 0

Substitute the first equation into the second equation to get:λ = p2,2λ = 2p1 ⇒ p2 = 2p1,

Substitute the first two equations into the third equation to get: x1 = I/3p1,x2 = I/5p2

Substitute p2 = 2p1 into the above to get:x1 = I/3p1,x2 = I/10p1.Substitute the values of p1, p2 and I into the above to get:x1 = 20/9,x2 = 4/3.The optimal choice is therefore (x1, x2) = (20/9, 4/3).
