A student studying for a vocabulary test knows the meanings of 16 words from a list of 26 words. If the test contains 10 words from the study list, what is the probability that at least 8 of the words on the test are words that the student knows? (Round your answer to three decimal places.)
To find the probability that at least 8 of the words on a 10-word test are known by a student, calculate the probabilities for exactly 8, 9, and 10 known words and sum them. Use combinations to determine the probabilities and round the final answer to three decimal places.
Explanation:The student knows 16 words out of 26, and the test contains 10 words. To find the probability that at least 8 out of 10 words on the test are known to the student, we need to calculate the probability for exactly 8, 9, and 10 known words, using combinations, and then sum these probabilities.
Let's denote K as knowing the word and N as not knowing the word. The total number of ways to choose 10 words out of 26 is given by 26 choose 10, denoted as C(26,10).
The probability of getting exactly 8 known words is given by (C(16,8) * C(10,2)) / C(26,10).
The probability of getting exactly 9 known words is (C(16,9) * C(10,1)) / C(26,10).
The probability of getting all 10 known words is (C(16,10) * C(10,0)) / C(26,10).
We add these probabilities together to get the total probability that the student knows at least 8 out of 10 words:
We sum these individual probabilities to obtain the final answer. The result should be rounded to three decimal places as per the instructions given in the question.

Translate this word phrase into an equation. one increased by two equals the quotient of nine and three
Final answer:
The translation of the word phrase into an equation is 1 + 2 = 9 ÷ 3. Solving the equation by performing division before addition verifies its correctness, resulting in 3 = 3.
Explanation:
The word phrase "one increased by two equals the quotient of nine and three" can be translated into an algebraic equation as follows:
1 + 2 = 9 ÷ 3
To solve the equation, perform the division on the right side of the equals sign first, as per the order of operations (PEMDAS/BODMAS), which states that division should be completed before addition:
1 + 2 = 3
Then adding the numbers on the left side:
3 = 3
This confirms that the given translation of the word phrase into an equation is correct, as both sides of the equation are equal.

A jewelry store is having a 10% off regular price sale. find the sale price of a ring normally priced at $ 1350
during a special sale all video games cost $26 & all movied cost $14. Jack plans to spend some or all of his $220 in bday money on these movies & video games.
WRITE AN INEQUALITY
The inequality that represents Jack's budget constraints for purchasing video games and movies is 26x + 14y ≤ 220, where x is the number of video games and y is the number of movies.
Explanation:To write an inequality representing Jack's spending on movies and video games with the given budget, we first assign a variable to the quantity of each item Jack could purchase. Let x represent the number of video games and y represent the number of movies. Since video games cost $26 each and movies cost $14 each, and Jack has $220 to spend, the inequality representing this scenario is:
26x + 14y ≤ 220
Here, x and y must be non-negative integers because you cannot purchase a negative amount or a fraction of a game or movie. This inequality ensures that the total amount spent on video games and movies does not exceed Jack's budget of $220.

FIND THE THIRD,FIFTH AND TENTH TERM SEQUENCE DESCRIBED BY EACH RULE
A(n)=4+(N-1)(-5)
A(N)=-2(n-1)(-5) ...?
To find the third term, substitute n = 3 into the formula A(n) = 4 + (n-1)(-5).
Explanation:The sequence A(n) is defined as 4 plus the product of (n-1) and -5. To find the third term, substitute n = 3 into the formula: A(3) = 4 + (3-1)(-5) = 4 + 2(-5) = 4 - 10 = -6.
To find the fifth term, substitute n = 5 into the formula: A(5) = 4 + (5-1)(-5) = 4 + 4(-5) = 4 - 20 = -16.
To find the tenth term, substitute n = 10 into the formula: A(10) = 4 + (10-1)(-5) = 4 + 9(-5) = 4 - 45 = -41.

During a period of deflation, the graph of the consumer price index (CPI) will rise.
A. True
B. False ...?
Final answer:
The statement is false; during a period of deflation, the Consumer Price Index (CPI) would decrease, not rise, reflecting a decrease in the average level of prices.
Explanation:
The answer to the student's question is B. False. During a period of deflation, the Consumer Price Index (CPI) would not rise; it would actually decrease. This is because deflation is characterized by a decrease in the average level of prices. For instance, during the Great Depression, a notable period of deflation, the CPI in the United States fell from 17.2 in 1929 to 12.9 in 1933, illustrating a decline in the general price level. Conversely, inflation will cause the CPI to rise because it reflects an increase in prices over time.
The Consumer Price Index is an economic indicator often used to measure inflation or deflation in an economy. A rise in CPI indicates inflation, whereas a drop indicates deflation. As inflation and deflation affect the real value of money, observing the changes in the CPI helps to understand the purchasing power of currency over time.
