The probability that the experiment results in 9 or more successes = 0.0676
A binomial distribution is given by,
P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ ,
where p is the probability of success and x is the random variable for success in n trials.
A binomial experiment has only two outcomes- success or failure.
Here, the number of trials, n = 10
Probability of success = 0.63
The probability for 9 or more success = P( X = 9, 10)
= P (X = 9) + P(X = 10)
So P( X = 9) = ¹⁰C₉ (0.63)⁹ (1-0.63)¹⁰⁻⁹
= 10 x 0.0156 x 0.37
= 0.05772
and P(X = 10) = ¹⁰C₁₀ (0.63)¹⁰(1-0.63)¹⁰⁻¹⁰
= 1 x 0.009849 x 1
= 0.009849
Hence probability for 9 or more success = 0.05772 + 0.009849
= 0.067569
= 0.0676
The question is incomplete. Find the complete question below:
A binomial experiment with probability of success 0.63 and 10 trials is conducted. What is the probability that the experiment results in 9 or more successes? Do not round your intermediate computations, and round your answer to three decimal places. (If necessary, consult a list of formulas.)

Trigonometry question
- Refer to the table below if needed.
- Choose the correct graph
1. Given that cos0 = -8/17 and sin0 is negative.
2. Given sec0 = -13/12, choose the two possible angles with domain 0 degrees 0[tex]\leq[/tex]0[tex]\leq[/tex]360 degrees.
3. 0 = 315 degrees
Using trigonometry, it is found that:
1. Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.
2. The angles are θ = 157.38º and θ = 202.62º, as shown in Graph 1.
3. Graph 3 shows an angle of θ = 315º.
Sine and cosine negativeIn item 1, it asks for an angle in which both the sine and the cosine of the angle are negative. This happens in the third quadrant, hence Graph 2 shows an angle in which cos(θ) = -8/17 and sin (θ) is negative.
SecantThe secant of an angle is given by one divided by the cosine of the angle, that is:
sec(θ) = 1/cos(θ)
Considering the numeric value of the secant in this problem, we have that:
-13/12 = 1/cos(θ)
-13cos(θ) = 12
cos(θ) = -12/13
The cosine is negative in the second and the third quadrant, hence graph 1 shows these equivalent angles.
Applying the inverse cosine, the angles are given as follows:
θ = arccos(-12/13)
θ = 157.38º and θ = 202.62º. (two equivalent angles).
Angle of 315ºAn angle of 315º is on the fourth quadrant of the unit circle, hence Graph 3 shows this angle.

The Solution:
Given the graph of f(x), we are required to determine whether the degree of the function is ODD or EVEN, and also to determine whether the function itself is ODD.
An odd function is defined as a function that has f(–x) = –f(x) for any value of x. The opposite input gives the opposite output.
From the given graph of f(x), the function f(x) is ODD.
The degree of the function f(x) is odd since the f(x) itself is odd.

C) No, 3 night does not cost half as much as the cost for 6 nights due to the addition mandatory cost of $15.
How to solve algebra word problems?We are told that a pet hotel charges $25 per night to keep a dog. We are also told that there is a mandatory $15 examination fee when the dog arrives there.
A) If the number of nights spent is n, then the function rule here for the total cost is;
T = 25n + 15
B) We are told that the number of nights is 6 nights. Thus, we will just plug in 6 for n into the total cost equation to get;
T(6) = 25(6) + 15
T(6) = $165
C) The cost of 3 nights would be;
T(3) = 25(3) + 15
T(3) = $90
This is more than half of the cost of 6 nights.

study was made of seat belt use among children who were involved in car crashes that caused them to be hospitalized. it was found that children not wearing any restraints had hospital stays with a mean of 7.37 days and a standard deviation of 3 days with an approximately normal distribution. (a) find the probability that their hospital stay is from 5 to 6 days, rounded to five decimal places. (b) find the probability that their hospital stay is greater than 6 days, rounded to five decimal places.
The probability that their hospital stay is greater than 6 days is equal to 0.67724 and the probability that their hospital stay is from 5 to 6 days is equal to 0.108
Mean (μ) = 7.37
Standard deviation (σ) = 3
we need to calculate probability that their hospital stay is from 5 to 6 days i.e.
⇒ P(5 < X < 6) = P(X < 6)-P(X < 5)
Here we will use standard normal distribution where,
Z-score = (X -μ )/ σ = (6 - 7.37)/3 = -0.46
Z-score = (5 - 7.37)/3 = -0.79
from Z table we found p-value
⇒P(5<X<6) = P(X<6) - P(X<5) = 0.32276 - 0.21476 = 0.108
So there is 0.108 probability that their hospital stay is from 5 to 6 days.
we need to calculate probability that their hospital stay is greater than 6 days i.e.
We get: P(X > 6) = 1 − P(X < 6)
Here we will use standard normal distribution where,
Z-score = (X - μ)/σ = (6 - 7.37)/3 = -0.46
from Z table we found p-value
P(X > 6) = 1 - P(X<6) = 1 - 0.32276 = 0.67724
So there is 0.67724 probability that their hospital stay is greater than 6 days.

c. Describe what happens to the function values in each function as x increases from left to right.
d. At what value(s) of x are the function values equal? If you cannot give exact values for x, give estimates.
For the given tables, we have that:
a. The grids are given at the end of the answer.
b. The functions are classified as follows: f(x) exponential, g(x) linear.
c. When x increases by one unit from left to right, we have that:
f(x) is multiplied by 4.g(x) is increased by 1.d. The functions are equal for a value between 1 and 2, as at x = 1 g(x) is greater while at x = 2 f(x) is greater.
Exponential and linear functionsThe difference between exponential and linear functions is in the rate of change, as:
Linear functions change by a constant amount when x changes by 1.Exponential functions change by a common ratio when x changes by 1.Hence the functions are classified as follows:
f(x) exponential: when x increases by 1, y is multiplied by 4.g(x) linear: when x increases by 1, y increases by 1.We have one exponential and one linear function, so it is quite difficult to solve an equation to verify where they are equal. We have that:
At x = 1, g(x) > f(x).At x = 2, f(x) > g(x).This means that at one point between x = 1 and x = 2, they intersected, that is, they had the same function values.

The ratio between Siu's height and the height of her brother Tai is 5:6. If
Tai is 145 cm tall, how tall is Siu, to the nearest centimetre?
With the concepts of ratio, Siu's height is 121 cm tall.
What is a ratio?We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part to part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.
A ratio is a comparison between two amounts that often uses a fraction.
Considering that the fraction has been simplified,
Given that Siu's height is 5x
Tai's height is 6x.
Now, 6x= 145
Thus, x= 145/6
Now, Siu's height is 5x
Then, its height is (145 ×5)/6= 120.8 cm
Siu's height is 121 cm because it must be rounded to the closest centimeter.

The equation for line s can be written as x - y = -2. Line t is perpendicular to lines and passes through (-4, 1). What is the equation of line t?
=========================================================
Explanation:
Anything perpendicular to Ax+By = C is of the form Bx-Ay = D
The given equation is x-y = -2 showing that A = 1, B = -1 and C = -2.
So Bx-Ay = D will update to -x-y = D
Plug in the coordinates of (-4,1) to find D.
-x-y = D
D = -x-y
D = -(-4)-1
D = 4-1
D = 3
We go from -x-y = D to -x - y = 3
Then multiply both sides by -1 to end up with x + y = -3

The simplified expression is [tex]x^8[/tex].
What is exponent?Exponent is the power of the variable or constant to which it is raised.
The expression 1 over x is denoted by 1/x.
The exponent of the obtained expression will be -8. So, the expression will be [tex](\frac{1}{x})^{-8}=\frac{1}{x^{-8}}[/tex].
The exponents of the denominator change from negative to positive when they move from denominator to numerator.
[tex]\frac{1}{x^{-8}}=x^8[/tex]
Thus, the simplified expression will be x raised to the power 8.
