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.)

Answers

To get the probability that at least 8 of the words on the test are words that students know we need to do the following calculations.

=[C(16,8)*C(10,2) + C(16,9)*C(10,1) + C(16,10)*C(10,0)] / C(26,10)

=0.132

Final answer:

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:

P(8 known words) = (C(16,8) * C(10,2)) / C(26,10)
P(9 known words) = (C(16,9) * C(10,1)) / C(26,10)
P(10 known words) = (C(16,10) * C(10,0)) / C(26,10)

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.

#SPJ2

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

Answers

$26g + $14m ≤ $220

g represents the number of video games bought
m represents the number of movies bought

Final answer:

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.

The discriminant D is found by this formula

D = b^2 - 4ac

there are 3 possible outcomes

1) If D is smaller than 0, ie D < 0, then there are no roots

2) If D is equal to zero (D = 0), then there is exactly one root. This root is rational assuming the coefficients are integers. This is called a double root

3) If D > 0, then there are 2 different roots. If D is a perfect square, then these two roots are rational numbers (aka fractions of whole numbers) assuming the coefficients are integers. If D is not a perfect square, then the two roots are irrational numbers.

Mr. jones has agreed to borrow $3500 for one year st 10% interest. what is the total amount he will pay back to the bank?

Answers

$ 3500 × 10 /100 × 1 = $ 3850

The total amount Mr. Jones will pay back after borrowing $3500 for a year at 10% interest rate is $3850, simply add the interest to the principal amount borrowed.

Mr. Jones borrowed $3500 for one year at 10% interest rate. The total amount he will pay back to the bank can be calculated as follows:

Interest = Principal x Rate = $3500 x 0.10 = $350

Total amount to be paid back = Principal + Interest = $3500 + $350 = $3850

An isosceles trapezoid has shorter base of measure a, longer base of measure c, and congruent legs of measure b. The perimeter of the trapezoid is 58 inches. The average of the bases is 19 inches and the longer base is twice the leg plus 7. Find the lengths of the sides.

Answers

Perimeter of the trapezoid = a + c + 2b
58 = a + c + 2b

Average of bases = (a + c)/2
19 = (a + c)/2
a + c = 38
Substituting (a + c) into the first equation:

58 = 38 + 2b
b = 10 in

We also know that:
c = 2b + 7
c = 2(10) + 7
c = 27 in

a + 27 = 38
a = 11 in

a = 11 in; b = 10 in; c = 27 in

The discriminant of a quadratic equation is negative. One solution is 3+4i . What is the other solution?
A.4-3i
B.3-4i
C.4+3i
D.-3+4i

Answers

I hope this helps you

3-4i

The way you stated the problem, there is an infinity of possibilities for the other solution.

► For instance, the quadratic equation:
   x² – (6 + 4i)x + (9 + 12i) = 0
has for discriminant:
   Δ = (6 + 4i)² – 4(9 + 12i) = 36 – 16 + 48i – 36 – 48i = -16
which is indeed negative.
Its solutions will then be:
   x₁ = [(6 + 4i) + 4i]/2 = 3 + 4i
   x₂ = [(6 + 4i) – 4i]/2 = 3
And the other solution here is 3.

► If you are not convinced, the quadratic equation:
   x² – (6 + 5i)x + (5 + 15i) = 0
has for discriminant:
   Δ = (6 + 5i)² – 4(5 + 15i) = 36 – 25 + 60i – 20 – 60i = -9
which is indeed negative.
Its solutions will then be:
   x₁ = [(6 + 5i) + 3i]/2 = 3 + 4i
   x₂ = [(6 + 5i) – 3i]/2 = 3 + i
And the other solution here is 3+i.

► In fact, every quadratic equation of the form:
   x² – [6 + (4 + α)i]x + (3 + 4i)(3 + αi) = 0
where α is any real, has for discriminant:
   Δ = [6 + (4 + α)i]² – 4(3 + 4i)(3 + αi)
      = 36 – (4 + α)² + 12(4 + α)i – 36 + 16α – 12(4 + α)i
      = 16α – (4 + α)²
      = 16α – 16 – 8α – α²
      = -16 + 8α – α²
      = -(α – 4)²
WILL be negative.
Their solutions will then be:
   x₁ = [ [6 + (4 + α)i] – (α – 4)i ]/2 = 3 + 4i
   x₂ = [ [6 + (4 + α)i] + (α – 4)i ]/2 = 3 + αi
And the other solution will then be is 3+αi.

Since α can take any real value, you'll obtain an infinity of solutions of the form 3+αi.

► So conclusively:
If the discriminant of a quadratic is negative AND one of the solutions is 3+4i, the only thing we can say about the other solution is that its real part must be 3.

Molly's basic cell phone plan charges $35.99 for service plus $0.21 per minute beyond the included 250 minutes in the plan. How much will it cost if she used her cell phone for 480 minutes in one month? ...?

Answers

The answer is $84.29

Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)

Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29

Solve -9-8(1+4h)=-17

Answers

-9-8(1+4h) = -17. We need to solve for h.
First, use the distributive property for 8(1+4h):
8(1+4h) = 8*1 + 8*4h = 8 + 32h

So -9-8(1+4h) = -17
-9 - (8+32h) = -17
-9 - 8 - 32h = -17
-17 - 32h = - 17
Add 17 on both sides to have the variables on a side and the numbers on the other:
-17 - 32h + 17 = -17 + 17
-32h = 0
divide both sides by -32 to get the variable h alone and its value on the other side:
(-32h)/-32 = 0/-32
h = 0.

So -9-8(1+4h) = -17 for h = 0.

You can recheck your answer (very important):
-9 - 8(1+4h) = -9 -8(1+4*0) = -9 - 8(1+0) = -9-8*1 = -9-8 = -17
The answer has been approved.

Hope this Helps! :)

Hi Jeannie

-9-8(1+4h) = -17
First, we need to distribute

-9 -8 - 32h = -17
-17 - 32h = -17
-32h = -17 + 17
-32h = 0
h = 0/-32
h = 0

23 + 45 - 48 + 34 * x = 292

What does x equal

Answers

Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 8

Simplifying
23 + 45 + -48 + 34x = 292

Combine like terms: 23 + 45 = 68
68 + -48 + 34x = 292

Combine like terms: 68 + -48 = 20
20 + 34x = 292

Solving
20 + 34x = 292

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right

Add '-20' to each side of the equation.
20 + -20 + 34x = 292 + -20

Combine like terms: 20 + -20 = 0
0 + 34x = 292 + -20
34x = 292 + -20

Combine like terms:
292 + -20 = 272 34x = 272

Divide each side by '34'.
x = 8

Simplifying x = 8

Translate this word phrase into an equation. one increased by two equals the quotient of nine and three

Answers

Here is the equation for this word phrase:
1 + 2 = 9 / 3
Quotient is the result of division.

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.

During a period of deflation, the graph of the consumer price index (CPI) will rise.

A. True
B. False ...?

Answers

The correct answer for this statement would be option B. FALSE. It is not true not during a period of deflation, the graph of the consumer price index or CPI will rise, but rather, it would show a downward pattern. The consumer price index measures changes in the price level of a market basket of consumer goods and services. Hope this answer helps.

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.
