Question:
Which of the following inequalities matches the graph?
Answer:
Looking at the graph the y values does not change, it stays at zero
The shaded area are the numbers under O
This means the answer is y ≤ 0
The answer is y ≤ 0
Hope it helps

Answers
Answer:
a) The estimated percentile for a student who scores 425 on Writing is the 30.5th percentile.
b) The approximate score for a student who is at the 87th percentile for Writing is 613.5.
Step-by-step explanation:
Problems of normally distributed distributions are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
a. What is the estimated percentile for a student who scores 425 on Writing?
This is the pvalue of Z when X = 425. So
has a pvalue of 0.3050.
The estimated percentile for a student who scores 425 on Writing is the 30.5th percentile.
b. What is the approximate score for a student who is at the 87th percentile for Writing?
We have to find X when Z has a pvalue of 0.87. So X for Z = 1.126.
The approximate score for a student who is at the 87th percentile for Writing is 613.5.

Final answer:
The number of aces in the first game and the number of spades in the 5th game follow a Hypergeometric Distribution while the number of games receiving at least one ace can be modeled by a Binomial distribution. The event of all cards being from the same suit can be thought of as a Uniform distribution.
Explanation:
a) The number of aces you get in the first game follows a Hypergeometric Distribution. In such a distribution, you are drawing cards without replacement. The parameters are N=52 (the population size), K=4 (the number of success states in the population i.e., the number of aces in a deck), and n=13 (the number of draws).
b) The number of games in which you receive at least one ace can be modeled by a Binomial distribution. Each game you play (out of 50) is a single trial, with the probability of success (getting at least one ace) being the same for every trial. The parameters are n=50 (the number of trials/games) and p (the probability of getting at least one ace).
c) The likelihood of all your cards being from the same suit in a game is heavily reliant on chance, can be modeled as a Uniform distribution given its rare occurrence. Essentially, the parameters would be minimum = 0 and maximum = 1. However, determining the parameters would require calculation of the specific probabilities, which is complex due to the nature of the game.
d) The number of spades you receive in the 5th game also follows a Hypergeometric distribution, similar to the situation in the first game. The parameters in this case are N=52, K=13 (number of spades in a deck), and n=13 (the number of drawn cards).

Answer:
d = 0
Step-by-step explanation:
To find the solution to the given equation, we must solve for d in the equation.
7.5d = 2.5d
Subtract 2.5d from both sides.
5d = 0
Divide both sides by 5.
d = 0
So the solution to the equation would be d = 0.
I hope this helps. Happy studying.
Final answer:
The provided equation 7.5d=2.5d seems to be flawed as these quantities cannot be equal unless the variable 'd' is zero. Please double-check the equation.
Explanation:
The equation given is 7.5d=2.5d. However, this equation cannot be correct as 7.5d and 2.5d cannot be equal unless the variable 'd' equals zero. It seems that there's a typo or mistake in the provided equation. The solution could not be found as the equation seems to be flawed. Please double-check the equation and make sure the coefficients (the numbers before the 'd') and the variable 'd' are correct.
