a business lady bought 100 quails and 80 rabbits for sh 25600.if she bought twice as many rabbits and half has many quails she would have paid sh7400 less.form two equations

The probability that the next fruit out of the bag is an apple is P = 4/5

We want to fnind the probability of randomly selecting an apple from the bag, where we assume that all the fruits have the same probability of being randomly selected.

Remember that the probability is equal as the quotient between the number of apples and the total number of fruit on the bag.

Originally, there are:

The checkout person takes 2 plums and 1 peach, so now there are:

For a total of 4 + 1 = 5 fruits

Then the probability of randomly grabing an apple is:

P = 4/5

Without any values of the functions f, g, h, and k, it is not possible to find the equation of each function. The equation of a function can be determined by analyzing the values of the function. Based on the given values, a possible equation can be found and then verified by plotting the points on a graph and seeing if they align with the equation.

It's important to note that the equation can be a linear or exponential equation but it's impossible to determine it without any values.

Answer:

Diameter is 8

Circumference is 8pi ~= 25.13

Step-by-step explanation:



The diameter is double the radius. So the given radius is 4 and double is 8.

The Circumference is given by C = pi•d or C = 2pi•r

Both of these equations will give the circumference.

C = pi•d

= pi•8

= 8pi ~= 25.13

OR

C = 2pi•r

= 2pi•4

= 8pi ~= 25.13

For finding the diameter, I multiply the radius by 2:

Diameter = 2 × radius

                = 2 × 4

                = 8

So the diameter is 8. As for the circumference, we can use two ways : either multiply pi times the diameter, or multiply 2 times pi times the radius.

The formulas are

C = πd              and C = 2πr

To find the circumference, stick in 8 for d:

C = π × 8

C = 25.13 units

The first five terms of the arithmetic sequence are given as follows:

3, -1, -5, -9, -13.

An arithmetic sequence is a sequence for which the difference between consecutive terms is constant, being called common difference d.

The recursive definition is given as follows:

f(n) = f(n - 1) + d.

For this problem, the definition is given as follows:

f(n) = f(n - 1) - 4.

Meaning that the common difference is of 4, and hence each term is obtained subtracting the first term by 4, starting with the first term given by f(1) = 3.

Step-by-step explanation:

The given triangle is obtuse triangle according to the corollary to the converse of the Pythagorean Theorem.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The triangle's longest side measures 15 units in length.

Compare the sum of the squares on the other two sides to the square that is the length of the longest side.

The square of the longest side is 15², which equals 225.

9² + 10² = 181 square units make up the sum of the squares on the other two sides.

Thus, 181 < 15².

As a result, the triangle is an obtuse triangle according to the corollary to the converse of the Pythagorean Theorem.

The number with the fewest  Decimal point will determine the number of significant figures in the calculated result.

The significant figures in the estimated result of an addition or subtraction calculation are determined by the decimal places of the measured values. This is so that the computed result can accurately reflect the precision of the measurement, which is shown by the decimal points in the measured values. Therefore, in the calculation with the fewest decimal places, the calculated result should have the same number of decimal places as the measured value. The result should have two decimal places, for instance, if one number has two decimal places and the other has four. By doing this, it is ensured that the result is not given a higher level of precision than the measured data utilized in the computation warrant.

Using mathematical operations, Ara's remaining pounds of apples are 1.405 pounds.

The four basic mathematical operations are addition, subtraction, division, and multiplication.

In this situation, we applied the mathematical operations of multiplication, addition, and subtraction to determine the difference (or the quantity of apples left) between the quantity brought to the market and the quantity sold.

The total quantity of apples = 35¹/₂ pounds

The quantity sold in the morning = ¹/₂  of 35¹/₂ pounds = 17.75 pounds

The quantity sold in the afternoon = ⁴/₁₉ of 35¹/₂ pounds = 7.47 pounds

The quantity sold in the evening = ¹/₄ of 35¹/₂ pounds = 8.875 pounds

The total quantity sold = (¹/₂ + ⁴/₁₉ + ¹/₄) = ³⁶/₃₈ of 35¹/₂ pounds = 34.095 pounds

The remaining pounds of apples = 1.405 pounds (35.5 - 34.095)

We know the fact that two event are independents if we have following:-

P(X and Y) = P(X) times P(Y)

For this problem, we must have P(blue and green) = P(blue) times P(green).

P(blue and green) = (3/10) * (1/5) = 3/50

But given P(blue and green) = 3/100

Since we have 3/100 ≠ 3/50

We know that the proportional relation between the number of inches that the candle has burned away, b, and the time in hours, t, is:

b = 1.5*t

The rate at which the candle burns is the amount burned in one unit of time, in this case, hours, then:

So, after t = 1 (one hour)

b = 1.5
