This is exponential growth

==========================================================

Explanation:

The exponential rule we need is:  a^(b*c) = (a^b)^c

Apply that rule and do a bit of rearranging:

y = 2(1.06)^(9t)

y = 2( (1.06)^9 )^t

y = 2( 1.68948 )^t

y = 2( 1 + 0.68948 )^t

y = 2( 1 + 0.69 )^t

The last equation fits the format of  y = a(1+r)^t  which tells us that...

Since r is positive, we have exponential growth. If r was negative, then we'd have exponential decay.

Answer:

Step-by-step explanation:

There are two ways to write the relationship, hence two constants of proportionality.

  d = kt

  k = d/t = (2 mi)/(30 min) = 1/15 mi/min

  t = kd

  k = t/d = (30 min)/(2 mi) = 15 min/mi

__

As you can tell from the way the constants are computed, they are reciprocals of each other.

267.95

Step-by-step explanation:

Sphere Volume = 4/3 π r³

a) The probability of having exactly 3 aces in a 7-card hand is approximately 0.0058.

b) The probability of having exactly 3 of a kind in a 7-card hand is approximately 0.0211.

The probability of drawing a specific card from a deck of 52 cards is 1/52.

a) To find the probability of having exactly 3 aces in a 7-card hand, we can use the binomial distribution:

P(exactly 3 aces) = (number of ways to choose 3 aces from 4 aces) * (number of ways to choose 4 non-aces from 48 non-aces) / (number of ways to choose 7 cards from 52 cards)

= (4C3 * 48C4) / 52C7

= (4 * 194580) / 133784560

= 0.005755

Therefore, the probability of having exactly 3 aces in a 7-card hand is approximately 0.0058.

b) To find the probability of having exactly 3 of a kind in a 7-card hand, we can use the following steps:

The total number of 7-card hands is 52C7 = 133,784,560.

Therefore, the probability of having exactly 3 of a kind in a 7-card hand is:

P(exactly 3 of a kind) = (13 * 4C3 * 12C4 * 4^4) / 133784560

= (13 * 4 * 495 * 256) / 133784560

= 0.02113

Therefore, the probability of having exactly 3 of a kind in a 7-card hand is approximately 0.0211.

Step-by-step explanation:

Answer:

For 7 houses you will need 5.83 acres of land and the builder will have 4.16 acres of land unused 

Step-by-step explanation:

The mean number of hours Hannah studied for her chemistry final in the last few days is 12 hours. To find the mean of the hours Hannah studied, you need to add up all the hours and then divide by the number of hours she studied. In this case, she studied for 8 days, so the mean can be calculated as follows: (13 + 12 + 11 + 10 + 7 + 14 + 12 + 17) / 8 = 12.5

Therefore, the mean of the hours Hannah studied for her chemistry final in the last few days is 12.5.
The given list of hours studied is: 13, 12, 11, 10, 7, 14, 12, 17.
First, let's add up these numbers: 13 + 12 + 11 + 10 + 7 + 14 + 12 + 17 = 96 hours.
There are eight days in total (as there are eight numbers in the list). Now, divide the total hours (96) by the number of days (8) to find the mean: Mean = 96 / 8 = 12 hours.

Answer:

Step-by-step explanation:

Answer:

3 pi 9

Step-by-step explanation:

If the builder does not build houses with three-car or more garages, then the probability that the buyer will select no garage home is 0.1.

Probability is a measure of likelihood that a certain event occurs. The probability of an event A is defined as:

P(A) = n(A)/n(S)

Where:

n(A) = number of ways the event A can occur

n(S) = number of all possible outcomes.

Suppose there are 3 possible outcomes, A, B, C, then:

P(S) = P(A) + P(B) + P(C) = 1

In the problem, let's define the events:

A = buyer will select a one-car garage

B = buyer will select a two-car garage

C = buyer will select no car garage

We have:

P(A) = 0.2

P(B) = 0.7

Hence,

P(A) + P(B) + P(C) = 1

0.2 + 0.7 + P(C) = 1

P(C)  = 1 - 0.9 = 0.1

Therefore, the probability that the customer will choose no garage option is 0.1

Step-by-step explanation:

general equation is (y-y1) = m(x-x1)

m=rise/run=  -4/1 (is negative because looking from left to right on the graph it goes downward)

pick any point on the line to put in. the equation for example (0,-3)

In Mathematics and Geometry, a number line simply refers to a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values (numbers) that are located at equal intervals along its length.

This ultimately implies that, all number lines would primarily increase in numerical value towards the right from zero (0) and decrease in numerical value towards the left from zero (0).

From the number line shown in the image attached below, we can logically deduce the inequality:

Answer:

People who bought tickets = 100%

                                             = 8000

People who bought their tickets in person = (100%-60%-15%) × 8000

                                                                       = 2000

The number of tickets sold online is 4800, by phone is 1200, and in person is 2000.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that there were 8000 people at the festival. people bought their tickets online, by phone, or in person. based on a random sample of people at the festival, 60% bought their tickets online, and 15% bought their tickets by phone.

The number of the tickets will be calculated as below:-

Total tickets = 8000

Online tickets = 60% of 8000 = 8000 x 0.6 = 4800

By phone = 15% of 8000 = 8000 x 0.15 = 1200

In-person = 25% x 8000 = 0.25 x 89000 = 2000

Therefore, the number of tickets sold online is 4800, by phone is 1200, and in person is 2000.

The congruence relation is used to define residue classes.

Congruence is an important idea in algebra that is often used to describe equivalence classes of integers modulo some integer n. A congruence relation on a set of integers is a binary relation that reflects equality modulo some integer n. Specifically, if a and b are two integers, then we say that a is congruent to b modulo n, or a ≡ b (mod n), if a - b is divisible by n.

The congruence relation is used to partition the set of integers into equivalence classes that are referred to as residue classes. Each residue class is represented by a single integer that is congruent to all the other integers in the class. In other words, a residue class is a collection of integers that have the same remainder when divided by n. There are exactly n residue classes modulo n, each of which is represented by a unique integer from 0 to n-1. Residue classes are used extensively in number theory and algebraic geometry, where they are used to study systems of equations and algebraic curves.

I think the correct answer is B :)

Answer:

60001 miles

Step-by-step explanation:

Given

\(Total\ Distance = 180000\)

Let the cars be: \(Car\ A, Car\ B\ and\ Car\ C\)

Assume that Car A has the minimum mileage of x.

\(Car\ A = x\)

The other cars would be:

\(Car\ B = x + 1\)

\(Car\ C = x + 2\)

This implies that Car C has the highest mileage

Required

Determine the possible minimum number of miles

Since the total distance is 180000, then:

\(Car\ A + Car\ B + Car\ C = 180000\)

Substitute values for Car A, B and C

\(x + x + 1 + x + 2 = 180000\)

Collect Like Terms

\(x + x + x = 180000-1-2\)

\(3x = 179997\)

Divide both sides by 3

\(\frac{3x}{3} = \frac{179997}{3}\)

\(x = \frac{179997}{3}\)

\(x = 59999\)

The car with the most mileage is Car C

So:

\(Car\ C = x + 2\)

Substitute 59999 for x in \(Car\ C = x + 2\)

\(Car\ C = 59999 + 2\)

\(Car\ C = 60001\)

The minimum distance travelled by Car C is 60001 miles

The power of the test is 0.75, which means that there is a 75% chance that the test will correctly reject the null hypothesis when it is false.

In statistical hypothesis testing, the null hypothesis is rejected when it is actually true. This mistake is known as a type I error or alpha error, and the probability of committing this mistake is called the level of significance, alpha. Type II error: In statistical hypothesis testing, the null hypothesis is retained when it is actually false. This mistake is known as a type II error or beta error, and the probability of committing this mistake is called the beta level, β.

The number of observations, n, in a sample is referred to as the sample size. The sample size is critical in determining the power of the test. Critical Value: A critical value is the dividing point between the parameter values for which the null hypothesis is rejected and those for which it is not. It separates the region of acceptance from the region of rejection. When the test statistic is greater than the critical value, we reject the null hypothesis.
