1) The sales tax for the toilet paper is $0.17.

2) The price of the coat is $43.63 and the sales tax is $2.24.

Step-by-step explanation:

1) Let the cost of the toilet paper be 'a'

Sales tax = 5.125%

Total cost = $3.50

Total cost = price+ 5.125% of price

3.50 = a + (5.125 x a/100)

3.50 = (100a + 5.125a) /100

350 = 105.125a

a = 350/105.125

a = $3.33

Sales tax = 3.50 - 3.33

= $0.17

The sales tax for the toilet paper is $0.17.

2)let the price of the coat be 'a'

cost of the coat = $45.87

Cost = a + 5.125% a

45.87 = a + (5.125/100) a

45.87 = ( 100a + 5.125a) /100

4587 = 105.125a

a = 4587/105.125

a = $43.63

Sales tax = 45.87 - 43.63

= $2.24

The price of the coat is $43.63 and the sales tax is $2.24

The result for the given 14 length bit string is-

(a) The bit strings of length 14 which have exactly three 0s is 2184.

(b) The bit strings of length 14 which have same number of 0s as 1s is 17297280.

(c) The bit strings of length 14 which have at least three 1s is 4472832.

<h3>What is a bit strings?</h3>

A bit-string would be a binary digit sequence (bits). The size of the value is the amount of bits contained in the sequence.

A null string is a bit-string with no length.

The concept used here is permutation;

ⁿPₓ = n!/(n-x)!

Where, n is the total samples.

x is the selected samples.

(a) Because there are exactly three 0s, its other digits have always been one, hence the total of permutations is equal to;

n = 14 and x = 3 digits.

¹⁴P₃ = 14!/(14-3)!

¹⁴P₃ = 2184.

Thus, the bit strings of length 14 which have exactly three 0s is 2184.

(b) Because it is a bit string with 14 digits and it can only have digits 0 or 1, we must choose 7 0s and the remaining 7 1s, hence the number possible permutations is equal to;

n = 14 and x = 7 digits.

¹⁴P₇ = 14!/(14-7)!

¹⁴P₇ = 17297280.

Thus, the bit strings of length 14 which have same number of 0s as 1s is 17297280.

(c) The answer is identical to problem a, but the rest of a digits could be either 0 or 1, hence it must be doubled by 2¹¹ because there are 11 digits, each of which can be one of two options;

= 2184×2¹¹

= 4472832

Thus, he bit strings of length 14 which have at least three 1s is 4472832.

The correct question is-

How many bit strings of length 14 have:

(a) Exactly three 0s?

(b) The same number of 0s as 1s?

(d) At least three 1s?

Write 3/2 as a mixed number
xenn [34]

Answer:

1\frac{1}{2}

Step-by-step explanation:

3/2 = 2/2 * 1/2

2/2 = 1

So 3/2 = 1\frac{1}{2}

I don’t know the answer to this question, could someone help me
Veronika [31]

we know that

domain is all possible values of x for which any function is defined

so, here domain will be all possible values of x fro which y is defined

so, we will find minimum and maximum value of x

we can see that

x starts from 0

so, minimum value is x=0

and it goes to right upto infinity

so, domain will be

x\geq 0...............Answer

PLEASE HELP MULTIPLE CHOICE
san4es73 [151]

Answer:

7. C

8. B

9. B

Step-by-step explanation:

7: A proper fraction is a fraction where the numerator is greater than the denominator. Choice <em>a</em> is a decimal, not a fraction. Choice <em>b</em> is a fraction, but its numerator is equal to its denominator. Choice <em>d</em> is also a fraction, but its denominator is greater than its numerator. Choice <em>c</em> is correct, because it is a fraction where its numerator is greater than its denominator.

8. A decimal fraction has denominators like 10, 100, 1000, as so on. It is a fraction.

9. A fraction is equal to the numerator divided by the denominator. When the numerator is equal to the denominator, the value of the numerator divided by the denominator is 1.
