Volume of figure A is 1375 cu ft

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.

Given,

Figure A ~ Figure B

In Figure A R = 5.

In Figure B R = 2.

Scale factor between Figure A and Figure B = 5/2

Volume of B = 88 cu ft

πR²h = 88

π2²h = 88

h = 88/4π

h = 22/π

Height of figure A = 5/2×height of figure B

Volume of figure A

= πR²h

= π5²×5/2×22/π

= 125 × 11

= 1375 cu ft

Hence, 1375 cu ft is volume of figure A.

The area of a triangle with the given base and height is 9.5625 square inches.

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given triangle, height is 2.5 inches.

By using Pythagoras theorem,

3²=x²+2.5²

9=x²+6.25

x²=9-6.25

x²=2.75

x=1.65 inches

So, the base = 6+1.65=7.65 inches

Area of a triangle = 1/2 ×7.65×2.5

= 0.5×7.65×2.5

= 9.5625 square inches.

Therefore, the area is 9.5625 square inches.

The altimeter will indicate a reading of 22,697 feet.

Standard deviation is a measure of variability in a dataset. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. This measure indicates how much variation exists in a dataset.

If you are at an altitude of Flight Level 230 (23,000 feet) and forget to set your altimeter to the local altimeter setting during descent, your altimeter will indicate different readings depending on the field elevation and the local altimeter setting.

To calculate the difference between the two, we use the standard deviation formula. Specifically, we calculate the difference between the local altimeter setting and the field elevation, and subtract that difference from the Flight Level. The standard deviation formula then looks like this:

Flight Level - (Local Altimeter Setting - Field Elevation)

In our example, the equation would look like this:

23,000 - (30.02 - 303) = 22,697

It is important to note that when making such calculations, the Flight Level should always be expressed in feet, rather than in thousands of feet.

By using the standard deviation formula and keeping track of settings like local altimeter setting and field elevation, pilots can ensure that their altimeter readings are accurate and that their aircraft will land safely

The required standard deviation of the new data set is 9.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

When 16 is added to each number in the data set, the variance of the new data set is not affected. The variance of a data set is the average of the squared deviations of the data values from the mean, and adding a constant to each data value shifts the mean but does not affect the deviations or their squares.

However, the standard deviation, which is the square root of the variance, will change because the standard deviation is expressed in the same units as the original data, while the variance is expressed in squared units. To find the standard deviation of the new data set, we need to take the square root of the variance, which is 81, and add 16 to each data value. The standard deviation of the new data set is equal to the square root of 81 + 16 = 9.

So, the standard deviation of the new data set is 9.

And vertical component is representing week days

The number of shirts sold  on Friday = 50

The number of shirts sold  on Saturday = 60

Percentage of sales on Friday = ?

Percentage of sales on Saturday = ?

Total sales = Monday + Tuesday + Wednesday + Thursday + Friday +            Saturday

The probability of getting a specific poker hand, consisting of five cards, dealt from a well-shuffled standard deck (no joker cards) can be found by using combinations and permutations.

The number of ways to choose five cards from a deck of 52 is given by the combination formula :

C(52,5) = 2,598,960

To find the number of ways to get a specific hand, we need to consider the number of ways to arrange the cards in that hand, which is given by the permutation formula :

P(5,5) = 5!.

For example, to find the probability of getting a straight flush, which is five cards of the same suit in numerical order, there are 4 possible suits, and 10 possible ways to get a straight (A, 2, 3, 4, 5; 2, 3, 4, 5, 6; ...; 9, 10, J, Q, K).

Therefore, the probability of getting a straight flush is:

4 * 10 / C(52,5) = 0.00139.

To find the probability of other hands, such as a flush, a full house, etc., we need to follow a similar process of counting the number of ways to get that hand and divide it by the total number of possible hands.

Frequency distribution  is a way to organize qualitative data into categories and record the number of observations in each category.

Differentiate between frequency distribution and relative frequency ?

A frequency distribution lists how frequently each category of data occurs, but a relative frequency analysis lists how frequently each types of information occurs.

One approach to organise data is to use a "frequency distribution," which can be done by listing the data, placing it in a table, or displaying it in a graph. Then, the list's entries (distinct values) are counted in terms of how frequently they have occurred.

Define relative frequency distribution

A "relative frequency distribution," on the other hand, refers to the percentage of the total number of observations that fall into a certain group. Divide each frequency by the total amount of data in the sample to obtain this.

Answer:

y = -0.916 * (1 - 0.140)^t

Step-by-step explanation:

f(t) = 0.4 * (1.16)^(t - 1)

To rewrite the equation in the form y = a(1 + r)^prime or y = a(1 - r)^prime, we can take the natural logarithm of both sides:

ln(f(t)) = ln(0.4) + (t - 1)ln(1.16)

ln(f(t)) = ln(0.4) + tln(1.16) - ln(1.16)

So,

y = ln(0.4) + tln(1.16)

Now we can rewrite this in the desired form by letting a = ln(0.4) and r = ln(1.16):

y = a + t * r

a = ln(0.4) = -0.916

r = ln(1.16) = 0.140

So,

y = -0.916 + 0.140 * t

y = -0.916 * (1 - 0.140)^t

This form of the equation shows that the function f(t) represents exponential decay. The value of "a" represents the initial value of f(t) and "r" represents the decay rate. Since r is negative, the function decreases over time, which means that the function represents exponential decay.

The probability that a randomly selected tire will have a life of at least 47,500 miles is 6.68%, which corresponds to answer choice c: .0668.

Probability is a mathematical concept that measures the likelihood or chance of an event occurring.It is a number between 0 and 1, with 0 designating an impossibility and 1 indicating a certainty. The probability of an event is calculated as the number of favorable outcomes divided by the number of possible outcomes.

The probability that a randomly selected tire will have a life of at least 47,500 miles can be found using a normal distribution and the z-score formula.

The z-score is calculated as follows:

z = (47,500 - 40,000) / 5,000 = 3.5

Using a standard normal table or calculator, we can find the cumulative probability associated with a z-score of 3.5. The probability that a randomly selected tire will have a life of at least 47,500 miles is:

P(X >= 47,500) = 1 - P(X < 47,500) = 1 - .9993 = .0007
