which is a better buy. 5 grapfruit for 1.99 or 8 grape fruit for 2.99

Answer: 2 1/2

Step-by-step explanation:

3 1/3 - 5/6 =  

(3*3+1 = 10/3 - both denominators (the bottom number) need to be the same so you need to make the mixed number 3 1/3 into an improper fraction first 10/3)

10/3 - 5/6 =

(10/3 * 2/2 = 20/6 - take the 10/3 and multiply by 2 which gives you 20/6)

20/6 - 5/6 = (now subtract which give you 15/6)

15/6 =

2 3/6 =

2 1/2 (lowest form)

The arc length of ST is 66r and the arc length of VSU is 270r, where r is the radius of the circle.

The length around the perimeter of any circle or curve is a better way to represent the length of an arc (arc). Each distance along the curved path that makes up the arc is measured by its length. An arc is a section of a curve or the outside of a circle. They are all curved in shape. The length of the arc is determined by the number of arcs in the arc (a chord). Based on measurements of the central angle (), which can be expressed in degrees or radians, we can calculate the arc length of a circle. The radius of a circle is multiplied by the arc length formula for circles.

The angles given are:

∠URT = 114°

∠URV = 90°

US is the diameter because it is a straight line passing through the centre of the circle.

Then ∠SRV = 90°

The total angle of the circle is 360°

Then,

∠SRT =  360 - ( 90 + 90 + 114)

     = 360 - 294 = 66°

Arc length of ST = radius * ∠SRT = 66r

Arc length of VSU = r * ∠VRU = r * (90 + 66 + 114) = 270r

Therefore the arc length of ST is 66r and the arc length of VSU is 270r, where r is the radius of the circle.

As per given the chord is 25 units,

Now, the other chord will be of same length,

and it is divided by the median,

Now, the length of x is 25/4 = 6.25

Probabilities are used to determine the chances of events

The given parameters are:

Using the binomial probability formula, we have:

\(P(X = x) = ^nC_x p^x(1 - p)^{n -x}\)

So, the equation becomes

\(P(x = 11) = ^{20}C_{11} \times (85\%)^{11} \times (1 - 85\%)^{20 -11}\)    

This gives

\(P(x = 11) = 167960 \times (0.85)^{11} \times 0.15^{9}\)

\(P(x = 11) = 0.0011\)

Express as percentage

\(P(x = 11) = 0.11\%\)

Hence, the probability that 11 out of the 20 would graduate is 0.11%

The probability 0.11% is less than 50%.

Hence, the extent that the university’s claim is true is very low

Using the binomial probability formula, we have:

\(P(X = x) = ^nC_x p^x(1 - p)^{n -x}\)

So, the equation becomes

\(P(x = 20) = ^{20}C_{20} \times (85\%)^{20} \times (1 - 85\%)^{20 -20}\)    

This gives

\(P(x = 20) = 1 \times (0.85)^{20} \times (0.15\%)^0\)

\(P(x = 20) = 0.0388\)

Express as percentage

\(P(x = 20) = 3.88\%\)

Hence, the probability that all 20 would graduate is 3.88%

The mean is calculated as:

\(\mu = np\)

So, we have:

\(\mu = 20 \times 85\%\)

\(\mu = 17\)

The standard deviation is calculated as:

\(\sigma = np(1 - p)\)

So, we have:

\(\sigma = 20 \times 85\% \times (1 - 85\%)\)

\(\sigma = 20 \times 0.85 \times 0.15\)

\(\sigma = 2.55\)

Hence, the mean and the standard deviation are 17 and 2.55, respectively.

The result of the normal probability distribution being bell-shaped is that the mean, median, and mode are at the center.

This means that the center of the bell-shaped curve represents the most likely occurrence of the data and that the values are symmetrically distributed around the mean.

The mean, median, and mode of a normal distribution are equal, which means that they are all located at the center of the bell-shaped curve. This is an important characteristic of the normal distribution and sets it apart from other distributions where the mean, median, and mode may not be equal.

In a normal distribution, the area on each side of the mean does not equal 1.00, but rather approaches 1.00 as the curve becomes more symmetrical. The height of the curve at the mean represents the highest probability of occurrence, and the probabilities decrease as the values deviate from the mean.

Blood Alcohol Content (BAC) is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume.

Here, the BAC = 0.1%

Time span = 4 hours

We know,

BAC is a measure of alcohol in the blood as a percentage

Alcohol leaves the body at an average rate of 0.015 g/100mL/hour

The model's rigging length of 326 feet is likely only a fraction of the total rigging on the real Lady Washington. Nonetheless, it is still an astonishing amount of string to work with when creating a model ship!

Assuming that the scale model is an accurate representation of the Lady Washington, we can use the model's rigging length to estimate the total rigging of the actual ship. The model has 326 feet of rigging, and if we know the scale of the model, we can determine the length of the real ship's rigging.
Unfortunately, without knowing the scale of the model or the dimensions of the actual ship, it is impossible to give an exact answer. However, we can make some educated guesses based on typical rigging lengths for ships of a similar size and type.
The Lady Washington is a replica of an 18th-century trading vessel, and based on historical records, we can estimate that a ship of this type and size would have had around 1,000 feet of rigging. This includes the standing rigging (which supports the mast and stays in place all the time), as well as the running rigging (which is used to adjust the sails).

Multiplication and division of regular numbers are the same as fractions and we will learn them with the multiplication and division of rational numbers worksheet.

To do the multiplication, first find the greatest common divisor of the numerator and the denominator. The factors are then grouped together so that the score equals one. Then multiply by the remaining factors. To divide, first rewrite the division as multiplication by the inverse of the denominator.

Thus, the exponential function written in the form of  y = abˣ is given as:  y = 7 (5)ˣ.

Calculating the exponential growth as well as decay of a given collection of data is done using an exponential function, which is a mathematical function.

Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.

Use the equation y = ab ,

Put the given points (0,7) and (3,875).

At, x = 0 and y = 7

7 = a(b)⁰

a = 7

And

At, x = 3 and y = 875

875 = 7(b)³  

b = \(125^{\frac{1}{3} }\)

b = 5

Then, y = abˣ

Put values of a and b.

y = 7 (5)ˣ

In the given statement is:

A sample n = 5 scores which means that there are 5 sample having m = 20 which is the arithmetic mean (A.M.)of these samples, and \(s^{2}\) = 4 is the variance of these samples.

Let us know the :

What is meant by Sample Standard deviation?

The sample standard deviation (s) is the square root of the sample variance and is also measure of the spread from the expected values.

Standard deviation is the square root of the variance.

Therefore, \(s^{2}\) =4 => s = 2

(Where, s denotes sample standard deviation ,σ)

Also, Standard error of the sample S(E) = Sample standard variance / \(\sqrt{number of samples}\)

= σ /\(\sqrt{n}\) = 2/\(\sqrt{5}\)

The value of Z is -27/37. To solve this problem, we will first simplify the expression on the left-hand side of the equation.

Using the distributive property of multiplication, we get:

(4+2n) = 2(2+n)

Next, we will simplify the expression on the right-hand side of the equation. We will use the complex conjugate to get rid of the imaginary part. The complex conjugate of (2+3i) is (2-3i), so we have:

(2+3i)*(2-3i) = 4 + 9 = 13

Now we have:

(4+2n)/(13) = (2+3i) + (3-2i)/(13)

To show that the left-hand side is a real number, we need to show that the imaginary part is equal to zero. We can simplify the right-hand side to get:

(2+3i) + (3-2i)/(13) = 2/13 + 3i/13 + 3/13 - 2i/13

The imaginary part is (3/13 - 2i/13), which is equal to:

(3/13) - (2/13)i

Since the denominator is a positive integer, we can see that the imaginary part is a multiple of (1/i), which is equal to -i. Therefore, the imaginary part is equal to zero, and the left-hand side is a real number.

To find the value of Z, we need to solve for (2n+4)/(13) = 2/13, which gives us n= -1. Substituting this value back into the original equation, we get:

(4+2(-1))/(13) = 2+3i + (3-2i)/(13)

2/13 = 2+3i + (3-2i)/(13)

Multiplying both sides by 13, we get:

2 = 26 + 39i + (3-2i)

Simplifying, we get:

-27 = 37i

Therefore, the value of Z is -27/37.
