A game show contestant must randomly select a door. one door doubles her money while the other three doors leave her bankrupt. what is the probability she selects the door that doubles her money

Answers

In this question, there is 1 door that doubles her money and 3 doors that leave her bankrupt which means there are 4 total doors. From those 4 doors, only 1 door that will double her money. Then the probability would be: 1 door / 4 doors = 1/4 = 25%

Cindy has 26 nickels. She is getting rolls of nickels from the bank. She has enough money to get up to 10 rolls of nickels and each roll contains 40 nickels. The bank will not give partial rolls. The function that models the number of nickels Cindy will have after leaving the bank is f(r)=40r+26, where r is the number of rolls of nickels she gets.

What is the practical domain of the function?

Answers

We know that the domain is actually the number of rolls that she gets because it is the input variable in the equation  f (r) = 40 r + 26. The number of rolls that she can get can never be a negative number nor a zero nor a decimal number. However she can only get up to 10 rolls. Therefore the answer is:

A new truck that sells for $25,000 depreciates (decreases in value) 11% each year. What will be the value of the truck in 2 years

Answers

Original price =$25,000
Depreciation rate = 11%

Note that 1 - 0.11 = 0.89.
Value after 1 year    = $25,000 (0.89) = $22,250
Value after 2 years = $22,250 (0.89) = $19,802.50

Answer: $19,802.50

Answer:

Price of Truck after 2 year = $ 19802.50

Step-by-step explanation:

Given: Price of truck = $ 25,000

           Price depreciate at rate of 11%  in a year

To find: Price of truck after 2 years

If we let Price of truck to be P = $ 25000

And Rate of deprecation to be R = 11%

And time to be n = 2

now by using formula of deprecation, we get

[tex]A=P\times(1-\frac{R}{100})^n[/tex]

[tex]A=25000\times(1-\frac{11}{100})^2[/tex]

[tex]A=25000\times0.7921[/tex]

A = $ 19802.50

Therefore, Price of Truck after 2 year = $ 19802.50

Which of these triangle pairs can be mapped to each other using a single reflection?

Answers

Answer:

The correct answer should be figure 1 which is also attached in the solution.

Step-by-step explanation:

Reflection of any object is the mirror image of the object about any line or plane. Reflection always shows a congruent figure but inverted.

In first figure, triangle EFG makes a mirror image as triangle FGL. Here, EG is equal to GL, EF is equal to FL and angle E is congruent to angle L.

So, the figure obtained is congruent and inverted. Thus, triangles can be mapped to each other in single reflection in this image.

Figure 2 shows two congruent triangles but the reflection is not a mirror image as it should be inverted.

Figure 3 shows two congruent triangles but here they are aligned in a similar manner and not inverted. So, it is incorrect.

Figure 4 has inverted and congruent triangles but the axis about which the image is taken doesn't match with them. While reflection, they will not overlap each other and hence, it is incorrect.

Therefore, the correct answer should be figure 1 which is also attached in the solution.

Jenny earned a 77 on her most recent test. Jenny’s score is no less than 5 points greater than 4/5 of Terrance’s score. If t represents Terrance’s score, which inequality represents the situation?

Answers

Answer:    

The situation is represented by the following inequality :

[tex]\bf 77\geq \frac{4}{5}\cdot t+ 5[/tex]

Step-by-step explanation:

Score earned by Jenny on her most recent test = 77

Let the Terrance's score is represented by t

[tex]\frac{4}{5}\text{ of the Terrance's score is = }\frac{4}{5}\cdot t[/tex]

If Terrance's score is 5 points greater then the points earned by Terrance's in the test is represented by :

[tex]\bf\frac{4}{5}\cdot t+ 5.......(1)[/tex]

Now, according to the given condition in the question , Jenny's score is not less than the score represented by (1)

⇒ Jenny's score is greater than equal to the score represented by (1)

Hence, The situation is represented by the following inequality :

[tex]\bf 77\geq \frac{4}{5}\cdot t+ 5[/tex]

Select the correct rate of change and y -intercept for the linear function that contains the points (4, 6) and (5, 3).

Question 1 options:

The rate of change is –3, and the y -intercept is 18.


The rate of change is 3, and the y -intercept is –6.


The rate of change is 1/3, and the y intercept is 4 2/3


The rate of change is -1/3, and the y intercept is 7 1/3

Answers

Hello,

The rate of change is the slope (rise/run, y/x). To find that, we use the equation (y2-y1) over (x2-x1). It means take the second "y" and subtract it from the first "y" and the same to "x". If I plug in the numbers, it would be (3-6) over (5-4), and after you subtract, the answer simplifies to: -3/ 1 which is -3. Yay! We got the slope (rate of change) done.

Now let's find the y-intercept by using the formula of point-slope form, 
y-y1= m (slope) (x-x1). This is saying you "y" is subtracted from the first 
"y" of the points which equals the slope (m) times the quantity of "x" subtracted by the first "x" of the points. 

Let's plug the numbers in: y-6 = -3 (x-4). Let's distribute -3 to the parenthesis, and after that it should simplify to: y-6 = -3x + 12. To get "y" by itself, add 6 to both sides: y = -3x +18. We have finally found the slope-intercept equation for those two points (4,6) and (5,3). To then find the y-intercept in this equation, it would be the 18, because -3 is the slope, so that makes 18 the y-intercept.

In conclusion, the rate of change is -3 and the y-intercept is 18

I hope this helps!

What are Natural Numbers?

Natural numbers are defined as which range from 1 to infinity and are the most fundamental sort of numbers. Commonly known as positive numbers or counting numbers, these numbers. Natural Numbers are represented by the symbol N.

What are Prime numbers?

Prime numbers are defined as any number that is any integer with exactly two factors 1 and the number itself. is said to be a prime number.

Given that

⇒ (1×2×3× . . . ×n) + 1

We have to determine the smallest natural number n, greater than 1, for which (1×2×3× . . . ×n) + 1 is not prime.

Here we substitute the value of n = 4 in the given expression,

A) f(x) = 3x, g(x) = x – 4
B) f(x) = x – 7, g(x) = x – 4/3
C) f(x) = 3x, g(x) = 3x
D) f(x) = 7, g(x) = 3x

Answers

Since we know that the two functions are equal, f (x) = g (x), therefore when we equate the two equations the result should be similar to 3x = x – 4:

 

A. f(x) = 3x, g(x) = x – 4

Equating the two functions:

3x = x – 4             (correct)

Final answer:

To evaluate the expression a³ - b/c for a = 3, b = 2, and c = 4, substitute the values and simplify to get 27 - 1/2, which equals 53/2 in simplest form.

Explanation:

To evaluate the expression a³ - b/c when a = 3, b = 2, and c = 4, you need to substitute these values into the expression and simplify.

Step 1: Substitute the given values. The expression becomes 3³ - 2/4.

Step 2: Calculate the power of 3. The expression is now 27 - 2/4.

Step 3: Simplify the fraction 2/4, which is equivalent to 1/2.

Step 4: The expression now reads 27 - 1/2.

Step 5: To subtract, convert 27 to a fraction which has the same denominator as 1/2. This gives us 54/2 - 1/2.

Step 6: Subtract the fractions which results in 53/2, which is the simplest form.

Answers

The answer is 4+8+16+32+64+128+256+512+1024: This is equivalent to 2044

Answer:  The correct option is (B) 2044.

Step-by-step explanation:  We are given to find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024.

We know that

the n-th term of a geometric sequence with first term a and common ratio r is given by

[tex]a_n=ar^{n-1}.[/tex]

According to the given information, we have

[tex]a=4[/tex]

and

[tex]ar^{9-1}=1024\\\\\Rightarrow 4\times r^8=1024\\\\\Rightarrow r^8=\dfrac{1024}{4}\\\\\Rightarrow r^8=256\\\\\Rightarrow r^8=2^8\\\\\Rightarrow r=2.[/tex]

Therefore, the sum of the 9-term geometric sequence is given by

[tex]S_9\\\\\\=\dfrac{a(r^9-1)}{r-1}\\\\\\=\dfrac{4\times(2^9-1)}{2-1}\\\\\\=\dfrac{4\times(512-1)}{1}\\\\=4\times511\\\\=2044.[/tex]

Thus, the required sum of the 9-term sequence is 2044.

Option (B) is CORRECT.
