Problem How many unique ways are there to arrange the letters in the
word CHRISTMAS?*
362,880
45,255
1
55,698
Answer:
There are 181,440 ways.
Step-by-step explanation:
Given the word CHRISTMAS
In the word "Christmas" there are 9 letters.
Also take note, the letter "s" is repeated twice.
Hence, the number of ways is given by; no of ways = n!/m!
Where, n = 9, m = 2
no of ways = 9 *8*7*6*5*4*2*1/2*1
no of ways = 9*8*7*6*5*4*3
no of ways = 181,440.
Therefore, the number of unique ways that the letters in the word can be arranged is 181,440.
Simplify: -2 1/3-(-10 1/6)
Answer:
exact form: 47/6 decimal form: 7.8333 mixed number form: 7 5/6
Step-by-step explanation:
-convert mixed numbers into improper fractions:
-7/3-(-61/6)
-least common multiplier for 3 and 6 is 3
-adjust fractions based on LCM
=-14/6+61/6
-since the denominators are equal, combine the fractions:
=-14+61/6
-add/subtract the numbers (-14+61=47)
Suppose that we are doing batch testing with batches of size 12. Suppose that the probability that a batch of size 12 tests negative is .655. Determine the expected number (expected value) of tests needed for a group of size 12.
Answer:
[tex]E(x) = 7.86[/tex]
Step-by-step explanation:
Given
Represent the size with n and the probability with p
[tex]n = 12[/tex]
[tex]p = 0.655[/tex]
Required
Determine the expected value; E(x)
[tex]E(x) = np[/tex]
[tex]E(x) = 12 * 0.655[/tex]
[tex]E(x) = 7.86[/tex]
Hence, the expected value is 7.86
The expected value is 7.86.
Important information:
Group size = 12Probability that a batch of size 12 tests negative is 0.655.We need to find the expected number (expected value) of tests needed for a group of size 12.
Expected value:The expected value is:
[tex]E(x)=np(x)[/tex]
Where, n is the batch size and p is the probability.
[tex]E(x)=12(0.655)[/tex]
[tex]E(x)=7.86[/tex]
Therefore, the expected value is 7.86.

Step-by-step explanation:
Undo the various operations done to F.
[tex]K=\dfrac{5}{9}(F-32)+273.15\quad\text{given}\\\\K-273.15=\dfrac{5}{9}(F-32)\quad\text{subtract 273.15}\\\\\dfrac{9}{5}(K-273.15)=F-32\quad\text{multiply by 9/5}\\\\\boxed{F=\dfrac{9}{5}(K-273.15)+32}\quad\text{add 32}[/tex]
How many terms of the arithmetic sequey(1,3,5,7,...)will give sum of 961
When we add odd numbers:
1 = 1
1 + 3 = 4
1 + 3 + 5 = 9
...
Notice that the sum of n terms is n²
* This is because an odd number is expressed as 2n-1, we would need to get the sum of all 2n-1 substituting the value from 1 to n. (This is summation)
So we would have 2(1+2+3+...+n) - n = 2[n(n+1)/2] - n = n(n+1) - n = n(n+1-1) = n²
So:
Sum of n terms = 961
Sum of n terms = 31² = n²
n = 31
There are 31 terms in the arithmetic sequence

Answer:

Step-by-step explanation:
A bird is attempting to fly northeast at a constant speed, but a wind blowing southward at 5 miles per
hour blows the bird off course. If the bird’s overall movement (incorporating its intended movement
and the movement due to wind) is at a speed of √53 miles per hour, how fast would it have been traveling if there was no wind?
Answer:
The value is [tex]v_b = 9.89 \ miles /hour[/tex]
Step-by-step explanation:
From the question we are told that
The velocity of the wind southward is [tex]v = 5 j \ miles / hour[/tex]
The resultant velocity of the bird with the with wind is [tex]V= \sqrt{53}[/tex]
Generally for an object moving in the northwest direction the angle with the horizontal is 45°
Generally the velocity of the bird in the along the x -axis is
[tex]V_x= v_b cos 45^o i[/tex]
Generally the velocity of the bird in the along the y -axis is
[tex] V_y=(v_b sin 45^o - 5)j[/tex]
Here [tex]v_b[/tex] is the velocity of the bird without the wind
Generally the resultant velocity of the bird with the with wind is mathematically represented as
[tex]V = \sqrt{V_x^2 + V_y^2 }[/tex]
=> [tex] \sqrt{53} = \sqrt{(v_b cos 45^o)^2 + (v_b sin 45^o - 5)^2 }[/tex]
Generally
[tex]sin 45^o = \frac{1}{\sqrt{2} }[/tex]
and
[tex]cos 45^o = \frac{1}{\sqrt{2} }[/tex]
So
[tex] \sqrt{53} = \sqrt{(v_b* (\frac{1}{\sqrt{2} ))^2 + ([v_b * (\frac{1}{\sqrt{2} ) ]- 5)^2 }[/tex]
=> [tex]53 = \frac{1}{2} v_b^2 + \frac{1}{2} v_b^2 + 5^2 -2*5 * \frac{1}{\sqrt{2} } v_b[/tex]
=> [tex] 53 = v_b^2 + 25 - 5 \sqrt{2} v_b[/tex]
=> [tex] v_b^2 - 5 \sqrt{2} v_b -28 = 0[/tex]
Solving the above quadratic equation using quadratic formula we obtain that
[tex]v_b = 9.89 \ miles /hour[/tex]
The other value is negative so we do not make use of it because we know that the bird is moving in the positive x and y axis

Answer:
x = 5Step-by-step explanation:
[tex]6 - 2x = 5x - 9x + 16[/tex]
Simplify
That's
[tex]6 - 2x = - 4x + 16[/tex]
Add 4x to both sides of the equation
[tex]6 - 2x + 4x = 4x - 4x + 16 \\ 6 + 2x = 16[/tex]
Subtract 6 from both sides of the equation
[tex]6 - 6 + 2x = 16 - 6 \\ 2x = 10[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{10}{2} \\ [/tex]
We have the final answer as
x = 5Hope this helps you

a spherical balloon is being inflated so that the radius is increasing at a rate of 3 cm/sec. find the rate at which the volume is increasing when r=10cm.
Answer: 1200pi cubic cm per sec
========================================
Work Shown:
dr/dt = 3 is the rate of change of the radius
V = (4/3)pi*r^3 ..... volume of a sphere
dV/dt = (4/3)*3*pi*r^2*dr/dt ... chain rule
dV/dt = 4*pi*r^2*dr/dt
dV/dt = 4*pi*r^2*3
dV/dt = 12*pi*r^2
dV/dt = 12*pi*10^2 ... plug in r = 10
dV/dt = 1200pi
