Answer:

P(B) = 0.20

Step-by-step explanation:

If A and B are events with P(A)=0.5, P(A OR B)=0.54, and P(A AND B)=0.16, find P(B).

Provide your answer below:

We are given two events A and B and the formula for the probability of two events is given as:

P ( A ∪ B) = P(A ) + P( B ) - P( A∩ B)

Where:

P(A)=0.5

P ( A ∪ B) = P(A OR B)=0.54

P( A∩ B) = P(A AND B)=0.16

P(B) = ??

Hence, we have:

0.54 = 0.5 + P(B) - 0.16

Making P(B) subject of the formula

P(B) = 0.54 - 0.5 + 0.16

P(B) = 0.20

Answer:

The answer is below

Step-by-step explanation:

The cost price (manufacturing price) of an article is Rs.50.

Retailer 1 marks his price 10% above cost, hence the selling price for retailer 1 is:

Selling price for retailer 1 = 10% of Rs.50 + Rs.50 = (0.1 * Rs.50) + Rs.50 = Rs.55

Retailer 2 sets a profit of 20% on his returns, hence the selling price for retailer 2 is:

Selling price for retailer 2 = 20% of Rs.50 + Rs.50 = (0.2 * Rs.50) + Rs.50 = Rs.60

The difference  between the retailers selling prices = Rs.60 - Rs.50 = Rs.10

The retailer with the highest price sells for Rs.60 and the difference between the retailers selling prices is Rs.10. For the profit to be equal, the percentage discount is:

Discount = (Rs.10 / Rs.60) * 100% = 16.67%

a. days                         1        2        3     4       5

number of gallons    12      24     36    48    60

b.     g = 12d    (the number of days times 12)

c.    a person uses 84 gallons of water for showering each week.

Step-by-step explanation:

each day is 12 gallons so just multiply the number of days by 12 to get how many gallons that you use in a set number of days. for the last one, a week is 7 days so if you do 7 x 12 then you get how many gallons a person uses in a week.

Answer:

single-channel, multi -phase

Step-by-step explanation:

The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.

From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.

Then, we have that from the single line initially, the queues then moves to multi -phase that is to  3 individual car wash stalls.

Answer:

c

Step-by-step explanation:

in upper triangle:

Tan60=p/b

    √3=a/6

∴a=6√3

again, sin60=p/h

√3 /2=6√3 /b

∴b=12

now, taking down triangle:

cos45=h/b

1/√2 =12/c

∴c=6√2

Answer:

b. 63 minutes

Step-by-step explanation:

Given;

number of times the hash function is applied  = 12

time taken to brute force one application, = 21 minutes

Apply proportion, bearing in mind that 4 available resources should take less time;

1 available resource ------- 21 minutes

4 available resources ------ x

Thus, x  = 21 minutes / 4

When applied  12 times, the time should be [tex]\frac{21 \ minutes}{4} \ \times \ 12 \ = 63 \ minutes \\\\[/tex]

Therefore, the correct option is B, 63 minutes

Answer:

p = -1  q = -4

Step-by-step explanation:

a system of eq and solve for p and q ???  can do  :)

Eq. 1)  8p + 2q = - 16

Eq. 2)  2p - q = 2

use Eq .2 and solve for q

2p - 2 = q

plug into Eq.1 with q

8p +2(2p - 2) = - 16

8p +4p -4 = -16

12p = - 12

p = -1

plug -1 into Eq. 1 for p and solve for q

8(-1) + 2q = - 16

-8 + 2q = - 16

2q = -8

q = -4

Answer:

Natasha can wrap 128 gifts in total

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ Natasha has 240 square feet of wrapping paper

∵ Natasha can wrap 8 gifts with 15 square feet

→ By using the ratio method

→  Gift  :  square feet

→   8     :  15

→   x      :  240

→ By using cross multiplication

∵ x × 15 = 8 × 240

∴ 15x = 1920

→ Divide both sides by 15

∵ x = 128

∵ x represents the number of gifts

∴ Natasha can wrap 128 gifts in total

Answer:

B) X-2

Step-by-step explanation:

The quotient of given polynomials division is (x-2). Therefore, option B is the correct answer.

A quotient is a quantity produced by the division of two numbers or two terms. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

The given polynomials are (x³+3x²-4x-12) and (x²+5x+6)

Here, (x³+3x²-4x-12) can be written as

x²(x+3)-4(x+3)

= (x+3)(x²-4)

= (x+3)(x+2)(x-2)

Now, (x²+5x+6) can be written as

x²+3x+2x+6

= x(x+3)+2(x+3)

= (x+3)(x+2)

So, (x+3)(x+2)(x-2)/(x+3)(x+2)

= (x-2)

Therefore, option B is the correct answer.

Answer:

we conclude that:

[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}\:=\:x^{a-b}[/tex]

[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=\left(\frac{2}{54}\right)^{-\frac{4}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]

         [tex]=\frac{1}{\left(\frac{2}{54}\right)^{\frac{4}{3}}}[/tex]

        [tex]=\left(\frac{1}{27}\right)^{-\frac{4}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]

        [tex]=\frac{1}{\frac{1^{\frac{4}{3}}}{27^{\frac{4}{3}}}}[/tex]

         [tex]=\frac{1}{\frac{1^{\frac{4}{3}}}{81}}[/tex]      ∵ [tex]27^{\frac{4}{3}}=81[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}[/tex]

         [tex]=\frac{81}{1^{\frac{1}{3}}}[/tex]              

[tex]\mathrm{Apply\:rule}\:1^a=1[/tex]

         [tex]=\frac{81}{1}[/tex]

          [tex]=81[/tex]

Therefore, we conclude that:

[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81[/tex]
