En red socks and ten blue socks are all mixed up in a dresser drawer. The 20 socks are exactly alike except for their colour. The room is in pitch darkness and you want two matching socks. What is the smallest number of socks you must take out of the drawer in order to be certain that you have a pair that match?

Answers

Answer 1

Answer:

3 socks

Step-by-step explanation:

Given that, there are 10 red socks and 10 blue socks which are mixed up in the dresser drawer.

The socks are identical except the color.

We need to find out, the minimum number of socks to be taken out from the dark room so that there is at least a pair of matching socks comes out of the drawer.

Let us consider the cases:

First Two socks pulled out of the drawer.

Case 1: Both are red or both are blue.

In this case, the matching pair is ready.

But there can be other case as well.

Case 2:

One red and one blue color taken out.

Now, when we pull the third, there will be either red or blue.

That will make a pair.

Therefore, to cover up all the cases and to be certain to get a matching pair out of the drawer, at least 3 socks must be taken out.

So, the answer is:

We need to take out at least 3 socks.

Answer 2

The number of socks that determines a matching pair is an illustration of probabilities

The smallest number of socks is 3

The number of socks is given as:

[tex]\mathbf{Red = 10}[/tex]

[tex]\mathbf{Blue = 10}[/tex]

There are two colors of socks in the drawer

This is represented as:

[tex]\mathbf{n = 2}[/tex]

So, the smallest number of socks to determine matching pair is

[tex]\mathbf{Smallest = n + 1}[/tex]

Substitute 2 for n

[tex]\mathbf{Smallest = 2 + 1}[/tex]

Add

[tex]\mathbf{Smallest = 3}[/tex]

Hence, the smallest number of socks is 3

What other information do you need to prove GHK ≅ KLG by SAS?
The image is a quadrilateral GHKL and a diagonal GK is drawn such that it forms two triangles GHK and KLG. Sides GL and KH are marked as congruent.

A. ∠KHG ≅ ∠GLK
B. ∠HGK ≅ ∠LKG
C. ∠GHK ≅ ∠KLG
D. ∠HKG ≅ ∠LGK

Answers

Answer: D. ∠HKG ≅ ∠LGK

Step-by-step explanation:

Given: Quadrilateral GHKL where diagonal GK is drawn such that it forms two triangles GHK and KLG.

Side GL  ≅  Side KH

Now, GK is common in both triangles GHK and KLG.

and GK ≅GK

SAS congruence rule: If any two sides and the angle included between the sides of one triangle are congruent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent.

So ∠HKG must be congruent to ∠LGK ( angles between the congruent sides).

Hence, the correct option is D. ∠HKG ≅ ∠LGK

Question:

What other information do you need to prove ∆ GHK ≅ ∆ KLG by SAS?

Find f (77)
f(p)=7/11p-10:
A: f(77)=59
B: f(77)=39
C: f(77)=49
D: f(77)=67

Answers

Answer:

I don't know, the way it is typed confuses me. Is it 7/11 TIMES p-10 or is p-10 with the 11 as the denominator?  but I do hope this helps:

Step-by-step explanation:

So first I subtracted 7/11 from each side:

f(p)-7/11=(7/11-7/11)p-10

Now we are left with f(4/11p)=p-10

Now to get the variable "p" on one side, I subtracted 4/11p from both sides:

f(4/11p-4/11p)=(p-4/11p)-10

Now we are left with f=7/11p-10

Now we want the "p" to be 1p so we multiply each side by the reciprocal of 7/11:

f(11/7)=(7/11*11/7)p-10

Now we have 1 4/7f=p-10

Now we subtract 4/7 from each side and get:

f=p-9 3/7

And that's as far as I could simplify it, sorry if it's wrong... lol

The required value of f (77) is 39 for the given equation. The correct answer would be an option (B).

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

f (p) = (7/11) p - 10

We have to determine the value of f (77) for the given equation.

As per the question, we have

f (p) = (7/11) p - 10

Substitute the value of p = 77 in the above equation,

f (77) = (7/11)(77) - 10

f (77) = 7 x 7 - 10

f (77) = 49 - 10

Apply the subtraction operation, and we get

f (77) = 39

Thus, the value of f (77) is 39.

Answers

Answer:

See the screenshot! :)

Step-by-step explanation:

we have a exponential function of the form

y=a([tex]b^x[/tex])

where

y ---> is the population of bacteria

x ---> the number of hours

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

a=700 bacteria

r=5%=5/100=0.05

so

b=1+0.05=1.05

substitute

y=700([tex]1.05^x[/tex])

For x=20 hours

substitute in the equation and solve for y

y=700(1.05)^20= 1,857 bacteria

A medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system. What is the half life of the medication, in hours? Round to one decimal place.

Answers

Answer:

4.8 hours

Step-by-step explanation:

The formula for half life is given as:

t½ = t × In(2)/In(No/Nt)

Where

t½ = Half life

t = time in hours = 4

No = Initial amount = 10mg

Nt = Final amount after 3 hours = 6.5 mg

t½ = 3 × In(2) /In(10/6.5)

t½ = 4.8271216522281 hours

Approximately = 4.8 hours

The half-life of the medication, in hours, is 4.8 hours.

Given that,

Medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system.

Based on the above information, the calculation is as follows:

The following formula should be used:

[tex]= t \times ln(2)\div ln(No\div Nt)[/tex]

 Here

t denotes the time in hours i.e. 4

No means the Initial amount i.e. 10mg

Nt means Final amount after 3 hours i.e. 6.5 mg

So,

[tex]= 3 \times ln(2) \div ln(10\div 6.5)[/tex]

= 4.82

 = 4.8 hours

Therefore we can conclude that the half-life of the medication, in hours, is 4.8 hours.

Write the equation of a line in slope intercept form giving the following:

A: m=2 (0,-7)

B: (3,-4) (-2,1)

C: f(2)=6 f(0)=5

Answers

Answer:

Equation of a straight line is given as y = mx+c

m = slope or gradient or dy/dx or y2 - y1/ x2 - x1

c = intercept

y = 2x - 7

y = -x + 1

y = 2x - 10

Step-by-step explanation:

Using y = mx+c

A. m=2 y=-7 x=0

-7= 2*0 + c

-7=c

y = 2*x - 7

y = 2x - 7

B. x1=3 x2=-2 y1=-4 y2=1

m = y2 - y1/ x2 - x1

m = 1+4 / -2-3

m = 5/-5 which is equal to -1

using any value for y and x, let's use x1 and y1

-2 = -1*3 + c

-2 = -3 + c

1 = c

y = -1*x + 1

y = -x + 1

C. x1=6 x2= 5 y1= 2 y2=0

m = y2 - y1/ x2 - x1

m = 0-2 / 5-6

m = -2/-1 which is equal to 2

using any value for y and x, let's use x1and y1

2 = 2*6 + c

2 = 12 + c

-10 = c

y = 2*x -10

y = 2x - 10

Step-by-step explanation:

To begin, we would start multiply both numbers one by one.

(6.3 x 10^6) - 4.9 x 10^4

6.3 x 10^6 = 6300000

4.9 x 10^4 = 49000

Now, subtract (6.3 x 10^6) and (4.9 x 10^4)

                          6300000.            49000

6300000 - 49000 = 6251000

So first things first, we can cancel out 2y from both equations because they are common factors.

So we are left with the equations:

7x=-13

and

5x=11

So we add the two common factors and get:

12x=-24

And now we divide on both sides and get:

x=-2
