According to Bill Nye, How many people need to be in a room for there to be 50% chance of atleast 2 people having the same birthday?a. 128 b. 56 c. 29 d. 12
Answer:
the answer is actually 23 people
Step-by-step explanation:
Bill Nye's birthday paradox can be explained in the following manner:
first we must find the probability that in a room with 23 people, no two people have the same birthday
probability of no two people having the same birthday = 365/365 x 364/365 x 363/365 x 362/365 ... you keep multiplying until 343/365 = 0.492703
so the probability that in a room with 23 people, no two people have the same birthday = 49.2703%
the probability of two people having the same birthday = 1 - probability of no two people having the same birthday = 1 - 49.2703% = 50.7297%

A cold water pipe can fill a swimming pool in 4 hours, and a hot water pipe in 6 hours. If cold water pipe is turned on and hot water pipe is turned on 3 hours later then how long will it take them to fill the pool together?
answer = 5
Step-by-step explanation:
A cold water pipe can fill a swimming pool in 4 hours
And a hot water pipe in 6 hours.
If cold water pipe is turned on and hot water pipe is turned on 3 hours later
6-4 = 2
2+3 = 5
5 answer
Answer:
0.6 of an hour
Step-by-step explanation:
A cold pipe takes 4h hours so we can assume ¼ of our job is done in one hour.
After 3 hours go by with the cold pipe on, we have ¼ of the job left.
Now we have our hot pipe, which takes 6 hours for the entire pool, so we can assume that it has a rate of ⅙ per hour. Now since these two pipes are working together we can add them.
⅙ + ¼ = ⁵/₁₂
Now we divide.
Since at the start 3 hours had gone by with the cold pipe that would have been ¾ of our time so, 1 - ¾ = ¼
¼ ÷ ⁵/₁₂ = ⅗ or 0.6 of an hour

Compute 41, 42, 43, 44, 45, 46, 47, and 48. Make a conjecture about the units digit of 4n where n is a positive integer. Use strong mathematical induction to prove your conjecture.
Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:
[tex]4^1 = 4\\4^2 = 16\\4^3 = 64\\4^4 = 256 \\4^5 = 1024\\4^6 = 4096\\4^7 = 16384\\4^8 = 65536[/tex]
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
[tex]4^1 = 4\\4^2 = 16[/tex] unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
Which term describes the figure? Please help
Answer:
C . None of these
Is the answer.
Step-by-step explanation:
Because parallel lines do not intersect.
And perpendicular lines form angle of 90°.
Answer:
None of the above.
Step-by-step explanation:
Those lines are intersecting lines. Parallel lines face each other and never meet. Perpendicular lines do meet, but they form a 90 degree angle, which this doesn't. Intersecting lines meet, but don't form a 90 degree angle.

Step-by-step explanation:
h(x) = -x - 3 when h(-6).
~Substitute
h(-6) = -(-6) - 3
~Simplify
h(-6) = 6 - 3
~Subtract
h(-6) = 3

Ffind an equation for the tangent to the curve at the given point. Then sketch the curve and the tangent together.
y=8 âx,(1,8)
Answer:
y = 4x + 4
Step-by-step explanation:
given :
y = 8 [tex]\sqrt{x}[/tex] , (1,8)
The equation for the tangent to the curve at the given point
y' = 8. ( [tex]( \frac{1}{2\sqrt{x} } ) = \frac{4}{\sqrt{x} }[/tex]
next calculate the slope of the tangent (m) = y' at x = 1 = 4
hence the equation of the tangent is
y - y' = m( x - x1 )
y - 8 = 4 ( x - 1 )
y = 4x + 4
attached below is the sketch of the curve and the tangent together

Given that R= 4x +6y find x when y= 4 and R=11
Answer:
The value of x:
[tex]x=-\frac{13}{4}[/tex]Step-by-step explanation:
Given the equation
[tex]R=4x+6y[/tex]
substituting the values y=4 and R=11
[tex]R=4x+6y[/tex]
[tex]11=4x+6\left(4\right)[/tex]
[tex]11=4x+24[/tex]
[tex]11-24=4x[/tex]
switching the sides
[tex]4x=11-24[/tex]
Subtract the numbers: 11-24=-13
[tex]4x=-13[/tex]
Divide both sides by 4
[tex]\frac{4x}{4}=\frac{-13}{4}[/tex]
[tex]x=-\frac{13}{4}[/tex]
Therefore, the value of x:
[tex]x=-\frac{13}{4}[/tex]¿ Qué porcentaje de 70 es 35?

The number 0.003 is 1/10 of which decimal?
Answer:
I'd say it's 0.03
Step-by-step explanation:
0.03 divided by 10 is 0.003 so it's 1/10
0.003 is 1/10th of 0.03.
What is a decimal ?A decimal is represented by a point or a dot it separates the decimal part and the fractional part for example 24.75 here the whole part is is 24 and the fractional part is 75.
if we divide 0.03 by 10 = [tex]\frac{0.03}{10}[/tex] = 0.003. (dividing a number by 10
moves the decimal point
to the left by 1 because
