The probability that Harry, Jason, and Sarah will all be accepted into their desired schools is;P(Harry, Jason, Sarah) = P(Harry) * P(Jason) * P(Sarah) = 0.1949 * 0.2413 * 0.1492 = 0.007 Possible answer: 0.007 (or 0.7%)

The solution to the question is given below; The mean score of the GMAT exam is μ = 550 and the standard deviation is σ = 115.There are three friends - Harry, Jason, and Sarah - who want to be admitted to business schools. Harry requires a score of 650 or above, while Jason requires a score of 630 or higher and Sarah requires a score of 670 or above. Because the admission procedure is independent for each of the friends, the joint probability can be calculated using the multiplication rule.

The probabilities that Harry, Jason, and Sarah will achieve the desired scores are calculated separately using the z-score equation, which is as follows;For Harry:Z = (650 - 550) / 115 = 0.87 Probability of Harry getting admitted = P(z > 0.87) = 0.1949 (using z-table)For Jason:Z = (630 - 550) / 115 = 0.7 Probability of Jason getting admitted = P(z > 0.7) = 0.2413 (using z-table)For Sarah:Z = (670 - 550) / 115 = 1.04 Probability of Sarah getting admitted = P(z > 1.04) = 0.1492 (using z-table)The probability that Harry, Jason, and Sarah will all be accepted into their desired schools is;P(Harry, Jason, Sarah) = P(Harry) * P(Jason) * P(Sarah) = 0.1949 * 0.2413 * 0.1492 = 0.007 Possible answer: 0.007 (or 0.7%)

The difference quotient for f(x)=x is (x+h-x)/h, which simplifies to 1/h. The average rate of change of f(x)=x on the interval (1,3) is 1/2, since h=2.

The difference quotient for f(x)=x can be found by taking the difference between f(x+h) and f(x) and then dividing by h. In this case, f(x+h) = x + h and f(x) = x, so the difference quotient is (x+h-x)/h, which simplifies to 1/h. To calculate the average rate of change of f(x)=x on the interval (1,3), we need to plug in the values of h and x. Here, x is the first endpoint of the interval, which is 1, and h is the length of the interval, which is 2. Thus, the average rate of change is 1/2.

The florist can make 23 bunches of flowers with the lilies, carnations, and roses they have for the wedding.

What is the ratio?

A ratio is a comparison of two or more quantities that indicates their relative sizes or amounts. It expresses the relationship between two or more numbers or values by dividing one by the other.

Let's start by finding out how many flowers in each bunch are lilies.

Since 60 percent of the flowers are lilies, we can calculate that 0.6 x 40 = 24 of the flowers in each bunch are lilies.

That means the remaining 16 flowers in each bunch are split between carnations and roses.

Let's use the ratio of 3:5 to split these flowers between carnations and roses.

First, we need to find the total number of parts in the ratio:

3 + 5 = 8

That means for every 8 flowers in the bunch, 3 are carnations and 5 are roses.

Now we can set up an equation to find out how many bunches of flowers the florist can make:

140 (number of carnations) ÷ 3 (number of carnations in each 8-flower group) = 46.67

So the florist can make 46 bunches of flowers with the carnations they have.

But we need to make sure that there are enough roses to go with these carnations.

If 3 of every 8 flowers in each bunch are carnations, that means 5 of every 8 flowers are roses.

So for each bunch, there are 5/8 x 16 = 10 roses.

To make 46 bunches of flowers, the florist will need 46 x 16 = 736 flowers in total.

If 24 of every 40 flowers in each bunch are lilies, that means 16 of every 40 flowers are carnations and roses combined.

So for 736 flowers, there will be 368 carnations and roses.

Since each bunch contains 16 flowers, the florist can make 368 ÷ 16 = 23 bunches of flowers with the carnations and roses they have.

Therefore, the florist can make 23 bunches of flowers for the wedding.

The 25 percent of 401.16m is equal to 100.29m, rounded to 2 decimal places as 100.30m.

To calculate 25% of 401.16m, we can use the formula:

percentage × value = result

where the percentage is 25%, the value is 401.16m, and the result is what we want to find.

So, we can write:

25% × 401.16m = (25/100) × 401.16m = 0.25 × 401.16m = 100.29m

Therefore, 25% of 401.16m is equal to 100.29m.

To round this to 2 decimal places, we need to look at the third decimal place, which is 9. Since 9 is greater than or equal to 5, we round up the second decimal place, which is 0. Therefore, the final answer rounded to 2 decimal places is:

100.29m rounded to 2 decimal places is 100.30m.

Step-by-step explanation:

The measurements for LM is 30 units and MN is 15 units.

We know that the scale factor for the dilation is 3, which means that each side of triangle RST was multiplied by 3 to create triangle LMN.

Therefore:

LM = 3(RS)

MN = 3(ST)

To find RS and ST, we can use the fact that TAN R = 5/2.5.

Recall that tangent is the ratio of the opposite side to the adjacent side of a right triangle, so we can set up the following equation:

TAN R = RS/ST = 5/2.5

Cross-multiplying, we get:

RS = 5ST/2.5

Simplifying:

RS = 2ST

Now we can substitute this expression for RS into the equations for LM and MN:

LM = 3(RS) = 3(2ST) = 6ST

MN = 3(ST)

So the measurements for LM and MN are:

LM = 6ST

MN = 3(ST)

From triangle RST,

ST = 5

LM = 6 x 5 = 30 units

MN = 3 x 5 = 15 units

Answer: To find out how long after the rocket is launched will it be 10 feet from the ground, we need to solve for t in the equation:

h = -16t^2 + 150t + 40

We know that when the rocket is 10 feet from the ground, h = 10:

10 = -16t^2 + 150t + 40

Subtracting 10 from both sides:

0 = -16t^2 + 150t + 30

Dividing both sides by -2:

0 = 8t^2 - 75t - 15

Using the quadratic formula:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 8, b = -75, and c = -15.

Plugging in these values:

t = (-(-75) ± sqrt((-75)^2 - 4(8)(-15))) / 2(8)

Simplifying:

t = (75 ± sqrt(5715)) / 16

Therefore, the rocket will be 10 feet from the ground approximately 0.26 seconds and 8.05 seconds after it is launched.

Step-by-step explanation:

a) The theoretical probability of a fair coin landing on heads is 1/2

b) The experimental probability of landing on heads is 40%. Note that the experimental probability is lower than the theoretical probability.

Part A: The theoretical probability of a fair coin landing on heads is 1/2 or 0.5. Thus, it is possible for either of the teams to get the ball first.

Part B: The frequency of each outcome after flipping the coin 10 times may vary, but for example:

Heads: 4

Tails: 6

The experimental probability of landing on heads can be calculated by dividing the frequency of heads by the total number of flips: 4/10 = 0.4 or 40%.

Comparing the experimental probability of 0.4 to the theoretical probability of 0.5, we can see that the experimental probability is lower than the theoretical probability.

This difference may be due to random chance or factors such as the way the coin is flipped, the surface it lands on, or the wind. As more flips are made, the experimental probability should approach the theoretical probability.

Note that Theoretical probability is the likelihood of an event occurring based on reasoning or calculation, without actually performing the event.

Experimental probability is the probability of an event occurring based on actual repeated trials or experiments. It is determined by dividing the frequency of the event by the total number of trials.

The standard deviation of the amount absorbed is 1819.9 ng/cm² rounded to one decimal place.

1. 80th percentile of the amount absorbed
Given that the amount (in ng/cm²) of active ingredient in the skin two hours after application is lognormally distributed with μ = 2.6 and σ = 2.1. The 80th percentile of the amount absorbed is to be found. Let X be the random variable representing the amount of active ingredient absorbed. We know that X follows a log-normal distribution with parameters μ = 2.6 and σ = 2.1. We are to find the value x such that P(X ≤ x) = 0.8We know that for a log-normal distribution X ~ log N (μ, σ). Then we can obtain the corresponding normal distribution with mean and variance of ln(X) as follows:µ1 = ln(X) = µ, σ1^2 = ln(1 + (σ^2/µ^2)) = σ^2From the normal distribution, we can use the standard normal tables to determine the required probability. Thus Z = (ln(x) - µ)/σ and P(X ≤ x) = P(Z ≤ (ln(x) - µ)/σ) = 0.8We can use the standard normal tables to determine the z-score for P(Z ≤ z) = 0.8, which is 0.84. Then we can find ln(x) using:0.84 = (ln(x) - 2.6)/2.1 or ln(x) = 2.6 + (0.84)(2.1) = 4.374x = e^4.374 = 79.1 ng/cm²Therefore, the 80th percentile of the amount absorbed is 79.1 ng/cm² rounded to one decimal place.2. Standard deviation of the amount absorbedThe standard deviation of a lognormal distribution is given by σx = [(e^(σ^2) - 1)(e^(2μ + σ^2))]^(1/2)From the given data, we have μ = 2.6 and σ = 2.1. Therefore,σx = [(e^(2.1^2) - 1)(e^(2(2.6) + 2.1^2))]^(1/2) = 1819.9 ng/cm² rounded to one decimal place. Therefore, the standard deviation of the amount absorbed is 1819.9 ng/cm² rounded to one decimal place.

In response to the question, we may say that  As a result, the angle of trigonometry inclination of the ramp is 4 degrees, to the closest degree.

The area of mathematics called trigonometry examines how triangle side lengths and angles relate to one another. The subject first came to light in the Hellenistic era, about in the third century BC, as a result of the use of geometry in astronomical investigations. The area of mathematics known as exact techniques deals with several trigonometric functions and possible computations using them. There are six common trigonometric functions in trigonometry. These go by the designations sine, cosine, tangent, cotangent, secant, and cosecant, respectively (csc). Trigonometry is the study of triangle characteristics, particularly those of right triangles. Consequently, studying geometry entails learning about the characteristics of all geometric forms.

The ratio of an angle's opposing side (such as the rise of a ramp) to its adjacent side is known as the tangent (the length of the ramp).

Angle's tangent is equal to its opposite and adjacent sides.

In this instance, the ramp's opposite side represents its 3/4-foot rise, and the ramp's adjacent side is its 12-foot length.

Angle's tangent is equal to 3/4 / 12 (or 0.0625).

We may take the inverse tangent (or arctangent) of this number to determine the angle itself.

Amount = arctan (0.0625)

Calculating the answer, we obtain:

Angle is 3.58 9 degrees.

When we convert this to degrees, we get:

a 4 degree angle

As a result, the angle of inclination of the ramp is 4 degrees, to the closest degree.

Answer:

Step-by-step explanation:

Let's break down the information provided in the problem:

The man spends 2/3 of his high salary on rent and food.

This means that he has 1/3 of his salary remaining.

He then spends 1/4 of this remaining amount on transportation.

He has 6000 rupees left.

To solve for the amount he pays on transportation, we can use the following steps:

Calculate the amount of money he has left after spending 2/3 of his salary on rent and food:

Remaining amount = (1/3) * high salary

Calculate the amount he spends on transportation using the information that he spends 1/4 of the remaining amount:

Transportation cost = (1/4) * remaining amount

Substitute the value of remaining amount from step 1 into step 2:

Transportation cost = (1/4) * [(1/3) * high salary]

We are given that the man has 6000 rupees left, so we can set the equation above equal to 6000 and solve for high salary:

(1/4) * [(1/3) * high salary] = 6000

Simplifying the equation above:

(1/12) * high salary = 6000

Solving for high salary:

high salary = 6000 * 12 = 72000

Finally, substituting high salary from step 6 into step 3 to find transportation cost:

Transportation cost = (1/4) * [(1/3) * 72000] = 6000

Therefore, the man pays 6000 rupees on transportation.
