What is the y-intercept in this problem?

To determine the price of the keyboard with the coupon, we need to know how much Tiana spent. Let's call the original price of the keyboard "x".

According to the coupon, Tiana will receive a discount of $150 for every $500 spent. So, if she spends x dollars, she will receive a discount of (x/500) * $150.

The price of the keyboard with the coupon will then be x - (x/500) * $150.

Since the original price is not specified, we cannot determine the exact price of the keyboard with the coupon.

Answer:

(2a - \(\frac{y}{4}\) )(2a + \(\frac{y}{4}\) )

Step-by-step explanation:

4a² - \(\frac{y^2}{16}\) ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

4a² - \(\frac{y^2}{16}\)

= (2a)² - (\(\frac{y}{4}\) )²

= (2a - \(\frac{y}{4}\) )(2a + \(\frac{y}{4}\) )

Answer:

Step-by-step explanation:

You must state the "price before tax".  Let this be P.  Also, you must state the sales tax rate.  Let this be r, where r is a decimal fraction.  

Then the sales tax is rP, the product of the tax rate and the "price before tax."

The total cost of the item (for which it is sold) is (P + rP)($40).

If P = $40 and the sales tax rate is 7%, then

this total cost is (1 + 0.07)P = 1.07P = $42.80

Your question would be clearer if you wrote it like this:  Given that the base price of an item is $40 and that the sales tax rate is 7%, find the total cost of the item with tax.  That would be (1 + 0.07)($40), or $42.80.

The sales tax is $42.80 - $40 = $2.80.

Answer:

Sales tax: 2.8$

Total cost: 42.8$

Step-by-step explanation:

the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 40 times .07=2.8. 2.8 plus 40= 42.8. hope this helps!!

The correct answer is c. I and III only.

Explanation:

i. As x → [infinity], f(x) → 2: This statement is true. As x approaches infinity, the exponential term -2^(-x - 2) approaches 0, and the constant term 2 remains. Therefore, the function approaches 2 as x approaches infinity.

ii. The x-intercept is (-2, 0): This statement is false. To find the x-intercept, we set f(x) = 0 and solve for x:

0 = -2^(-x - 2) + 2

2^(-x - 2) = 2

Taking the logarithm of both sides:

(x + 2) = log2(2)

(x + 2) = 1

x = -3

Therefore, the x-intercept is (-3, 0), not (-2, 0).

iii. The function is an example of exponential decay: This statement is true. The function f(x) = -2^(-x - 2) + 2 is a decreasing function as x increases. As x becomes larger, the exponential term -2^(-x - 2) becomes smaller, causing the function to approach 2, which is the horizontal asymptote. This behavior is characteristic of exponential decay.

In summary, based on the given options, statements i and iii are true, while statement ii is false. Therefore, the correct answer is c. I and III only.

Answer:

  angles (W, X, Y) = (77°, 62°, 41°)

Step-by-step explanation:

Given:

  ΔWZY

  ∠W = 2(∠Y) -5°

  ∠X = ∠Y +21°

Find:

  ∠X, ∠Y, ∠W

Solution:

Using angle measures in degrees, we have ...

  ∠X + ∠Y + ∠Z = 180

  (∠Y +21) +∠Y + (2(∠Y) -5) = 180

  4(∠Y) +16 = 180 . . . . . simplify

  ∠Y +4 = 45 . . . . . . . . . divide by 4

After analyzing the given question we reached the conclusion that the given statement is true.

When estimating a certain population parameter for instance mean there is a computation of confidence interval to get a sense of the precision of the estimate.

A population parameter is a sequence that presents like  an entire group or population. It is majorly used in inferential statistics to measure the nature and features of the given population. Examples of  population parameter are mean, variance, standard deviation.

A confidence interval refers to a range of values above and below the point estimate within which the true value of the population stays with a certain optimized level of confidence.

Even if an office manager placed an order for n desk chairs, n is not greater than 24.

When determining if n is greater than 24, it is important to consider the cost of delivery. In this case, the cost of delivery for an order of desk chairs is $10.00 for the first chair, and $1.00 for each additional chair in the order. This means that if n is greater than 24, the total cost of delivery would be more than $24.00, which is not the case.

Therefore, n is not greater than 24. Furthermore, if n was equal to 24, the total cost of delivery would be $34.00, which is also not the case. Thus, n is not greater than 24. In conclusion, the cost of delivery for an order of desk chairs affects the answer to the question of whether n is greater than 24.

The measure of the angle ∠G to the nearest tenth will be 31.6°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The length of the perpendicular is 28.2 units and the length of the base is 45.8 units, Then the measure of the angle ∠G is calculated as,

tan G = Perpendicular / Base

Substitute the value, then the angle is given as,

tan G = 28.2 / 45.8

tan G = 0.6157

G = 31.6°

The measure of the angle ∠G to the nearest tenth will be 31.6°.

1. The 100 prisoner experiment: 100 prisoners are about to be executed (you can use paper stick figures to model 100 prisoners, or you can do about 10), but the warden has agreed to allow all prisoners to be commuted to a 6-month sentence if they can pass one game. The game states that 100 pieces of paper with each of the prisoner's numbers are to be randomly shuffled into boxes that have random prisoner's numbers (where the number on the paper does not match the number on the boxes.) Each prisoner is allowed to open 50 boxes to find their number such that they have a \(\frac{1}{2}\) chance of finding their number. If you find your number, you are cleared to another room to wait. If you don't, then you've messed up huge. If even one prisoner does not find their number, all the prisoners die. If all of the prisoners find their numbers, they all get 6-month sentences instead. The chance of all the prisoners randomly finding their numbers is \((\frac{1}{2})^{100}\), which is about a 0.0000000000000000000000000000008% chance. 30 zeros after the decimal placement. For reference, two people have a better chance of picking up the same grain of sand from any of the beaches in the world than finding their numbers randomly.

The Vickrey Auction can be modeled into an experiment by testing people's psychological thinking. You can do this with any of your friends. In a Vickrey auction, you put your bids into a closed letter. For an item, the highest bidder wins the auction, but does not pay what he or she put their bid under in the auction, but rather pays what the second bidder had bidded. It teaches people to be more honest, because if you bid the highest and win, you pay the second-highest bidder's payment, which could also be almost equally as high and could cost you a fortune for an undervalued item.

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.
