A fair tossed 10 times . Find the probability of obtaining (i) exactly four heads (ii) 3 heads and 7 tails (iii) at least one head
Answer:
0.205 ; 0.117 ; 0.999
Step-by-step explanation:
Using binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of success, p = 0.5
P(x = 4) = 10C4 * 0.5^4 * 0.5^6
P(X = 4) = 0.205078125
B.) 3 heads and 7 tails
P(X = 7) = 10C7 * 0.5^7 * 0.5^3
P(X = 7) = 120 * 0.0009765625
P(X = 7) = 0.117
P(atleast one head)
P(x greater than equal to 1) = p(x =1) +... P(x = 10)
Using a binomial probability calculator :
P(x greater than equal to 1) = 0.999

Answer:
x = 6
Step-by-step explanation:
Tip: You want to isolate the x-variable on one side of the equation to find its value.
1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.
2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.
3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.
4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.
I hope that helps! :)

lines m and p are cut by the transversal n. determine the value of x. write the measures of the six angles. show all work
x = 36
Step-by-step explanation:
The angles 4x and x are supplementary, meaning they add up to 180; therefore we have
[tex]4x + x = 180[/tex]
[tex]5x = 180[/tex]
dividing both sides by 5 gives
[tex]x = 36[/tex]
the measure of angle x is 36 and that of 4x is 4 * 36 = 144
The angle opposite to 4x also measures 144 and the one opposite to x is 36.
Answer:
x° + 4x° = 180°
5x° = 180°
x° = 180°/5
x° = 36°

Find the value of x.
Answer:
x = 62°
Step-by-step explanation:
the top-most angle in the top isosceles triangle must be 73° also
the third angle of the top isosceles triangle is (180 - 73 + 73) which is 34°
the left portion of the right angle must be 56°
you can find by using this equation: x + x + 56 = 180
2x = 124
x = 62
L U C K luck is parallelogram with ∠C=68° and ∠LUK=42° find: 1.
m∠ CUK 2. m∠ K
Answer:
1. m∠CUK = 70°
2. m∠K = 112°
Step-by-step explanation:
1. The given parameters of the parallelogram LUCK are;
∠C = 68°
∠LUK = 42°
From the diagram of parallelogram LUCK obtained from an online source, we have;
Given that LUCK = A parallelogram, we have;
The same side interior angles ∠C and ∠U are supplementary angles
Therefore;
∠C + ∠U = 180°
∠U = 180° - ∠ C
∴ ∠U = 180° - 68° = 112°
∠U = 112°
By angle addition property, ∠U = ∠LUK + ∠CUK
∴ m∠CUK = ∠U - ∠LUK
By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;
m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°
m∠CUK = 70°
2. By angle addition property, we have;
∠K = ∠LKU + ∠CKU
∠LKU and ∠CUK are alternate interior angles
∴ ∠LKU = ∠CUK = 70°
Similarly, ∠CKU and ∠LUK are alternate interior angles
∠CKU = ∠LUK = 42°
m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°
m∠K = 112°.

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)
Congruent: Choose one of the vertical angle pairs I listed above
Step-by-step explanation:
Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.
Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual
Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Use the arithmetic series formula to calculate the sum of the first 15 terms of the sequence: a n =5n+3
Answer:
S₁₅ = 645
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Using the nth term formula [tex]a_{n}[/tex] = 5n + 3 , then
a₁ = 5(1) + 3 = 5 + 3 = 8
a₂ = 5(2) + 3 = 10 + 3 = 13 , then
d = a₂ - a₁ = 13 - 8 = 5
Thus
S₁₅ = [tex]\frac{15}{2}[/tex] [ (2 × 8) + (14 × 5) ]
= 7.5( 16 + 70)
= 7.5 × 86
= 645

which is the solution set for the quadratic equation x^2-9=0
===================================================
Explanation:
We could add 9 to both sides, and then apply the square root to both sides. Don't forget about the plus minus
x^2 - 9 = 0
x^2 = 9
x = sqrt(9) or x = -sqrt(9)
x = 3 or x = -3
To check these answers, you replace x with those values we found. I'll show you how to check x = 3
x^2 - 9 = 0
(3)^2 - 9 = 0
9 - 9 = 0
0 = 0
So that confirms x = 3. The confirmation for x = -3 is nearly the same. Keep in mind that (-3)^2 = (-3)(-3) = 9. You'll be squaring the negative as well.
------------------
Another method you could do is to use the difference of squares rule
x^2 - 9 = 0
x^2 - 3^2 = 0
(x - 3)(x + 3) = 0
Now apply the zero product property. This effectively means you set each factor equal to zero and solve for x
x-3 = 0 or x+3 = 0
x = 3 or x = -3
We end up with the same solution set.
Yet another method you could use is the quadratic formula, but that may be overkill. It's still good practice to do.
Graphing is a visual way to find the answers. You'll graph y = x^2 - 9 and look to see where the curve crosses or touches the horizontal x axis.
The measures of the three angles of a
triangle are given by 2x + 6, x, and 3x.
What is the measure of the largest angle?
Answer:
[tex]\boxed {\boxed {\sf 87 \ degrees}}[/tex]
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.
[tex]2x+6+x+3x=180[/tex]
Combine like terms (all terms with an x) on the left side.
[tex](2x+x+3x)+6=180[/tex]
[tex]6x+6=180[/tex]
Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.
[tex]6x+6-6=180-6\\6x=174\\[/tex]
x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.
[tex]6x/6=174/6 \\x=29[/tex]
Substitute 29 for x in the angle measures.
2x+6= 2(29)+6=58+6=64x=29 3x= 3(29)=87The largest angle is 87 degrees.

In an all boys school, the height of the student body are normally distributed with a mean of 69 inches and a standard deviation of 5 inches. using the empirical rule, what percentage of the boys are between 54 and 84 inches tall?
Answer:
99.7% of the boys are between 54 and 84 inches tall.
Step-by-step explanation:
The heights 54 and 84 inches are 3 standard deviations away from the mean. Thus, 99.7% of the boys are between 54 and 84 inches tall.
The percentage of the boys are between 54 and 84 inches tall is 99.7%
What is percentage?
Percentage a relative value indicating hundredth parts of any quantity.
What is empirical rule?
The empirical rule or the three-sigma rule , is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations of the mean.
The empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).
From question mean(μ) = 69 in. and standard deviation(σ)= 5 in.
(µ ± σ) = (69 ± 5)
=64 - 74
=68%
(µ ± 2σ) =(69 ± 10)
=59 -79
=95%
(µ ± 3σ) =(69 ± 15)
=54 -84
= 99.7%
Thus the percentage of the boys are between 54 and 84 inches tall is 99.7%

What is the height of the scoop if its volume is 75pi cm cube
Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9
