ben payed $900 for a sofa. The price of the sofa Juana was 2/3 the price ben payed. How much did Juana pay for her sofa?

Answers

Answer: $600

Step-by-step explanation:

Find 2/3 of $900.

To do this, we have to get 9 and divide by 3.

9 ÷ 3 = 3

Multiply 3 by 2. You get 6.

Add two zeros.

You will get $600.

Put a lid on it! The supplier is considering two changes to reduce to 1% the

percentage of its large-cup lids that are too small. One strategy is to adjust the

mean diameter of its lids. Another option is to alter the production process,

thereby decreasing the standard deviation of the lid diameters,

a. If the standard deviation remains at o = 0.02 inch, at what value should the

supplier set the mean diameter of its large-cup lids so that only 1% are too

small to fit?

b. If the mean diameter stays at = 3.98 inches, what value of the standard

deviation will result in only 1% of lids that are too small to fit?

c. Which of the two options in parts (a) and (b) do you think is preferable? Justify

your answer. (Be sure to consider the effect of these changes on the percent of

lids that are too large to fit.)

Answers

Answer:

A) 3.996 inches

B) 0.01

C) option B

Step-by-step explanation:

Note: The diameter of the lid is between : 3.95 and  4.05

A) calculate the supplier set mean diameter

std = 0.02 inch

P( x < 3.95 ) = 1% = 0.01

= P ( Z < [tex](\frac{3.95 - u }{0.02})[/tex] ) = P ( Z < -2.3263 ) = 0.01

therefore :

[tex](\frac{3.95 - u }{0.02})[/tex]  = -2.3263

hence : u = 3.996 inches ( mean diameter )

B) At mean diameter = 3.98 calculate the value of std

P ( X < 3.95 ) = 0.01

= P ( Z < [tex]( \frac{3.95-3.98 }{std } )[/tex] )  = P ( Z < -2.3263 ) = 0.01

therefore

[tex]( \frac{3.95-3.98 }{std } )[/tex] = -2.3263

hence std = 0.01 inch

C) option B is preferable because its mean diameter is smaller and  the percent of lids too large to fit is considered more carefully using option B

Elena wants to make a scale drawing of her apartment. Her apartment is a rectangle with length 18cm and width 10m. She decides on a scale of 1cm to 2m. What are the dimensions of the scale drawing of Elena's apartment, using a scale of 1cm to 2m. The answer should look like: __cm and__cm)

Answers

Answer:

9cm and 5cm

Step-by-step explanation:

 Note: The unit of the width in the question is suppose to be in cm

     "with length 18cm and width 10m"====>>> "with length 18m and width 10m"

so given that the dimension of the room is

18mx10m

This is a reduction process since we aim to transfer the dimension to paper

we are reducing the dimension by 2

and 1cm---2m

since 2m will represent 1cm

then the dimension will be

9cm and 5cm

Answers

Answer:

∠ Q = 75°

Step-by-step explanation:

Since PR and PQ are equal then the triangle is isosceles, thus

the base angles R andQ are congruent

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

x + 2x + 15 + 2x + 15 = 180, that is

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Thus

∠ Q = 2x + 15 = 2(30) + 15 = 60 + 15 = 75°

please help me, i don't understand this at all :(

Answers

i don’t know how much this will help as i don’t know the specific methods used in your lesson, but what i personally do is break down the number as much as i can.

32 can be simplified to 2^5. this is the fourth root, so you take out four of the 2’s to the outside by the 6. therefore it becomes 6(2) which = 12 along with the other 2 and an x left inside the fourth root “house”. btw i would write it out but brainly doesn’t let me attach pictures for some reason, and i don’t have the symbols on my keyboard. ):

we now simplify 512 in the second term. 512 is the same thing as 32 times 16, which is 2^9. we take out four of the 2’s, leaving us with 2^5. we can take four more 2’s out, leaving us with a 2 and an x in the inside of the fourth root “house”. on the outside we have 2 2’s, leaving us with a product of 4.

third term. 16 can be simplified to 4^2, or 2^4. we can take all four of them out since it’s the fourth root. there are also four x’s, so we take them out, leaving us with 2x. there isn’t anything left in the “house”.

now, we go from left to right. to better illustrate it, i will use “{ }” as the fourth root.

12 {2x} - 4 {2x} + 2x

8 {2x} + 2x . that’s as simplified as it can get. hopefully this helps! ):

June has a savings account with an annual simple interest rate of 2.6%. She hopes to gain $6,500 in interest over a period of eleven years. To accomplish this, June invested $17,801 in the account, but later realized that this was not enough money. To the nearest dollar, how much more money should June have initially invested to reach her goal?

Answers

Answer:

Step-by-step  think she needs 2.73861528462

The amount of money invested in an account with simple interest at an annual rate of 2.6% would be $22,727.27.

What is simple interest?

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

Simple Interest = (Principal × Rate × Time) / 100

Given that June has a savings account with an annual simple interest rate of 2.6%. She hopes to gain $6,500 in interest over a period of eleven years.

Rate = 2.6 %

Therefore, Simple Interest = (Principal × Rate × Time) / 100

Simple Interest = P× 2.6% × 3

6,500  = P× 2.6/100 × 3

P = 22,727.27

Hence, the amount of money invested in an account with simple interest at an annual rate of 2.6% would be $22,727.27.

The number line is shaded from the circle to positive 5.

Answers

Given:

The inequality is

[tex]5.25-b\geq 6.5[/tex]

To find:

The solution of the given inequality on the number line.

Solution:

We have,

[tex]5.25-b\geq 6.5[/tex]

Subtract 5.25 from both sides.

[tex]5.25-b-5.25\geq 6.5-5.25[/tex]

[tex]-b\geq 1.25[/tex]

Multiply both sides by -1 and change the sign of inequality.

[tex]b\leq -1.25[/tex]

The value of b always less than or equal to -1.25. Since -1.25 included in the solution set, therefore there is a solid circle on -1.25.

-1.25 lies between -2 and -1. It means the solid circle lies between -1 and -2.

[tex]b\leq -1.25[/tex], so the number line is shaded from the circle to negative 5.

A number line going from negative 5 to positive 5 is the required solution if a solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5.

A thief steals an ATM card and must randomly guess the correct three-digit pin code from a 7-key keypad. Repetition of digits is allowed. What is the probability of a correct guess on the first try? The number of possible code is__?? (Type an integer or fraction. Simplify your answer) The probability that the correct code is given in the first try is __?? (Type an integer or fraction. Simplify your answer.)

Answers

Answer:

1/343

Step-by-step explanation:

Given that:

Required pass code = 3 digit long

Digit or keypad option / length = 7

What is the probability of a correct guess on the first try? To obtain this,

Probability = required outcome / Total possible outcomes

The required outcome = correct guess; which is a single combination of the right digits = 1

Total possible outcomes = number of available combinations or the number of possible codes = (7^3) = 343

Hence,

P(right guess on first try) = required outcome / Total possible outcomes

= 1/343

Claire and Richard are both artists. Claire uses the polynomial 50x^2+250 to decide how much to charge.Richard uses the polynomial 49x^2+350 to charge how much to charge for his painting.In each polynomial x is the height of the paintings feet. To the nearest tenth what height will both Claire and Richard charge for the same amount for a painting?

Answers

Answer:

The height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.

Step-by-step explanation:

The polynomial expression representing the charge for Claire's paintings is:

C = 50x² + 250

The polynomial expression representing the charge for Richard's paintings is:

R = 49x² + 350

Here x represents the height of the paintings feet.

Now compute the value of x such that both Claire and Richard charge the same amount as follows:

C = R

50x² + 250 = 49x² + 350

50x² - 49x² = 350 - 250

x² = 100

x = 100

Thus, the height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.

find the perimeter of a circle whose diameter is 12.6 cm please help and show working The rule (x, y)(x1, y-3) represents a translation 1 unit ____ and 3 units ____ Data Structure in C++Using namespace std;In this assignment you will implement a variation of Mergesort known as a bitonic mergesort, recursively.In a normal mergesort, the input to the merge step is a single array, which is divided into two sections, both sorted ascending. We assume that the first half (0 up to but not including size/2) is the first section and the second half (size/2 up to but not including size) is the second section.In a bitonic mergesort, we use the same arrangement, except that the second sequence is sorted in descending order: the first half goes up, and then the second half goes down. This means that when we are doing a merge, sometimes we want to merge the results into ascending order, while other times we want to merge into descending order (depending on which "half" of the final array the result will end up in). So we add another parameter, to describe the direction the output should be sorted into:void merge(int* input, int size, int* output, bool output_asc);If output_asc == true then after the merge output should contain size elements, sorted in ascending order. If output_asc == false, output should contain the elements sorted in descending order.The other thing we glossed over in class was the allocation of the temporary space needed by the algorithm. Its quite wasteful to allocate it in each recursive call: it would be better to allocate all the necessary space up front, and then just pass a pointer to it. In order to do this, well write the recursive mergesort function in a helper function which will preallocate the space needed for the results:int* mergesort(int* input, int size) {int* output = new int[size];mergesort(input, size, output, true);return output;}void mergesort(int *input, int size, int* output, bool output_asc) {// Your implementation here}The parameter output_asc serves the same purpose here as for merge: it tells the function that we want the output to be sorted ascending.InterfaceYou must implement the functionsvoid merge(int* input, int size, int* output, bool output_asc);int* mergesort(int* input, int size);void mergesort(int *input, int size, int* output, bool output_asc);Download a template .cpp file containing these definitions. This file is also available on the server in /usr/local/class/src.merge must run in O(n) time with n= size. mergesort (both versions) must run in O(nlogn) time, and must use O(n) space. If you allocate any space other than the output array, you should free it before your function returns.The test runner will test each function separately, and then in combination. It checks the result of sorting to make sure that its actually sorted, and then nothing is missing or added from the original (unsorted) sequence. Is 3,600 rational?
