To get second discount, 90% of the price must be > $100  

hence 90% of 199.99 = 199.99/100*90 = $179.991 (Price after 1st discount)

Since the price after first discount is > $100 , it is eligible for second discount.  

Price after 2nd discount of 10% = 179.991/100*90 = $161.9919

Savings = 199.99-161.9919 = 37.9981 = 38 dollars saved.

Step-by-step explanation:

199.99 * 0.9 = 179.99

179.99 * 0.9 = 161.99

199.99 - 161.99 = $38 amount saved

The probability that in the next six tries the number of free throws he will make is at least 4 is 0.74431 and at most 3 is 0.25569.

1. At least 4 free throws made:

The number of free throws the player will make in the next six tries follows a binomial distribution with parameters n = 6 (number of trials) and p = 0.7 (probability of success in each trial).

To find the probability that the player makes at least 4 free throws in the next six tries, we need to calculate the probabilities of making 4, 5, or 6 free throws, and add them up:

P(X ≥ 4) = P(X = 4) + P(X = 5) + P(X = 6)

where X is the random variable representing the number of free throws made.

Using the binomial probability formula, we can calculate these probabilities:
- Probability of making 4 free throws: (6 choose 4) * 0.7⁴ * 0.3²
- Probability of making 5 free throws: (6 choose 5) * 0.7⁵ * 0.3¹
- Probability of making 6 free throws: (6 choose 6) * 0.7⁶ * 0.3⁰

where "choose" is the binomial coefficient (6 choose 4) = 6!/(4!2!) = 15, and so on.

Getting the sum of these probabilities will give the probability of making at least 4 free throws.

P(X ≥ 4) = 0.324135 + 0.302526 + 0.117649 = 0.74431

2. To find the probability of making at most 3 free throws, we can use the complement rule:

P(X ≤ 3) = 1 - P(X ≥ 4) = 1 - 0.74431 = 0.25569

Therefore, the probability of making at least 4 and at most 3 free throws in the next six tries is:

P(3 ≤ X ≤ 4) = P(X ≤ 3) + P(X ≥ 4) = 0.25569 + 0.74431 = 1.0

This makes sense, since the player must make either at least 4 or at most 3 free throws in the next six tries, so the sum of these probabilities is 1.

Answer:

20 painters are painting the inside

Step-by-step explanation:

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

Step-by-step explanation:

We are asked to express 2x+3y=-5 in the form ax+by+c=0

The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:

List 4.

A sample space is a set that contains all possible outcomes in the context of an experiment.

The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.

Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:

4 x 4 = 16.

This means that the correct list is either the list 3 or the list 4.

As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.

Since the result is negative, it means you incurred a loss of $33.28 from this transaction. Therefore, the correct answer is not among the options provided.

In general, "loss" refers to something that has been damaged or destroyed, or the amount of something that has been lost.

In the context of machine learning, "loss" refers to a mathematical function that measures the difference between the predicted output of a model and the actual output. The goal of a machine learning algorithm is to minimize this loss function during training, so that the model can make accurate predictions on new data.

Given by the question:

To calculate your net profit, you need to take into account the transaction costs, which include brokerage fees and any other fees that may be associated with buying and selling stocks.

Assuming a brokerage fee of $5 per trade, the total cost of buying the shares would be:

$11.95/sh x 266 shares = $3,181.70 + $5 = $3,186.70

The total cost of selling the shares would be:

$11.87/sh x 266 shares = $3,158.42 - $5 = $3,153.42

Your net profit would be the difference between the total cost of selling the shares and the total cost of buying the shares:

$3,153.42 - $3,186.70 = -$33.28

There is no solution to the system in its original form. There are no points in common. If the signs are reversed, the system has an intersection with an infinite number of solutions.

Step-by-step explanation:

The sample response :D

The length of segment AB, denoted as |AB|, is 50 yards. To find the length of segment AB, we can use the concept of vector addition and subtraction.

We can break down Leigh's movements into two components: the north-south component and the east-west component.

1. North-South Component: Leigh initially walks 40 yards south and then 10 yards north, resulting in a net displacement of 40 - 10 = 30 yards south.

2. East-West Component: Leigh walks 60 yards west and then 20 yards east, resulting in a net displacement of 60 - 20 = 40 yards west.

Now, we can find the length of segment AB by applying the Pythagorean theorem. The north-south and east-west components form a right triangle, where the length of segment AB is the hypotenuse.

Using the Pythagorean theorem: |AB|² = (north-south component)² + (east-west component)²

                          |AB|² = 30² + 40²

                          |AB|² = 900 + 1600

                          |AB|² = 2500

Taking the square root of both sides: |AB| = √2500

                                      |AB| = 50

Therefore, the length of segment AB, or |AB|, is 50 yards.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A linear function has an x-intercept of -8 and a y-intercept of 4.

So, The two points on the line are (- 8, 0) and (0, 4).

Now, slope(m) = (4 - 0)/(0 + 8).

slope(m) = 4/8.

slope(m) = 1/2.

The probability that one of the scores in the sample is less than 1484 is 0.2437 .

a)Given that mean u = 1403

standard deviation σ = 200

sample size n = 32

P(x>1484) = P(X-u/σ > 1484-1403/200)

                = P (z > 0.405)

P(x>1484) = 0.2437 .

hence the probability that one score is greater than 1484 is 0.405 .

b) Now we have to find the average of the scores of 48 samples.

P(x>1484)

= P(x-μ/ σ/√n> 1484-1403 /200/√48)

= P(z>2.805.)

Now we will use the normal distribution table to calculate the p value to be 0.002516.

p-value = 0.0025

Normal distributions are very crucial to statistics because not only they are commonly used in the natural and social sciences but also to describe real-valued random variables with uncertain distributions.

They are important in part because of the central limit theorem. This claim states that, in some cases, the average of many samples (observations) of a random process with infinite mean and variance is itself a random variable, whose distribution tends to become normal as the number of samples increases.
