We can see here that the measure that Raul should use to find the distance that the ball travels during each hit varies, on average, from the mean distance is the measure of variability known as standard deviation.
What is mean?The mean, commonly referred to as the arithmetic mean or average, is a statistic that depicts the usual or centre value of a dataset. It is determined by adding up all of the dataset's values, then dividing by all of the values.
We can see here that standard deviation actually refers to the statistical measure that represents the amount of dispersion or variability in a dataset.

Let us assume that the left right triangle be ABC and the right triangle on the right side be ABD.
So, the larger right triangle would be DAC.
Consider thr outer right triangle DAC.
The length of the hypotenuse DC would be,
DC = CB + BD
DC = 3 + 7
DC = 10 units
Also right triangle ABC and DAC are similar triangles.
We know that the sides of the smilar triangles are in proportion.
Using the definition of similar triangles for DAC and ABC,
DA/AB = AC/BC = DC/AC

if a1= 9 and =-3a n-1 then find the value of a5
If a₁ = 9 and sequence aₙ = -3aₙ₋₁ , then the value of a₅ is approximately equal to 729.
To find the value of a₅, we need to use the recursive formula provided, which relates each term in the sequence to the previous one. The formula given is a bit unusual, as it defines each term in terms of the negative three times the previous term. However, we can use this information to work out the value of a₅.
Starting with a₁ = 9, we can use the recursive formula to find the next few terms of the sequence:
a₂ = -3a₁ = -3(9) = -27
a₃ = -3a₂ = -3(-27) = 81
a₄ = -3a₃ = -3(81) = -243
a₅ = -3a₄ = -3(-243) = 729
Therefore, the value of a₅ is 729. We can check that this is correct by verifying that it satisfies the given recursive formula:
a₄ = -3a₃ = -3(81) = -243
a₅ = -3a₄ = -3(-243) = 729
This confirms that our solution is correct.

Part(A),
The estimated area under the graph of f(x) over the interval [3, 5] using four rectangles and right endpoints is approximately 0.231 square units.
Part(B),
The estimated area under the graph of f(x) over the interval [3, 5] using four rectangles and left endpoints is approximately 0.2405 square units.
To estimate the area under the graph of f(x) = 1/(x²+1) over the interval [3, 5] using four rectangles and right endpoints, we can use the following formula:
[tex]R_n = \dfrac{(b-a)}{n} \times [f(x_1) + f(x_2) + ... + f(x_n)],[/tex]
where a = 3, b = 5, n = 4, and xi = a + i(b-a)/n for i = 0, 1, 2, ..., n.
Using this formula with the right endpoints, we get:
[tex]R_4 = \dfrac{(5-3)}{4 }\times [f(3.5) + f(4) + f(4.5) + f(5)][/tex]
R₄ = (1/2) x [0.361 + 0.250 + 0.178 + 0.132]
R₄ = 0.231
Hence, the estimated area under the f(x) graph utilizing four rectangles and the right endpoints over the range [3, 5] is about 0.231 square units.
To repeat the approximation using left endpoints, we can use the following formula:
[tex]L_n = \dfrac{(b-a)}{n} \times [f(x_0) + f(x_1) + ... + f(x_{n-1)],[/tex]
where [tex]x_i = a + i\dfrac{(b-a)}{n}[/tex] for i = 0, 1, 2, ..., n-1.
Using this formula with left endpoints, we get:
[tex]L_4 = \dfrac{(5-3)}{4} \times [f(3) + f(3.5) + f(4) + f(4.5)][/tex]
L₄ = (1/2) x [0.250 + 0.361 + 0.250 + 0.178]
L₄ = 0.2405
Therefore, the estimated area under the graph of f(x) over the interval [3, 5] using four rectangles and left endpoints is approximately 0.2405 square units.

Jenny has recently begun keeping her spending under better control, but she
still can't fully pay off her credit card. She maintains an average monthly
balance of about $1100, and her card charges a 24% annual interest rate,
which it bills at a rate of 2% per month.
How much is she spending on credit card interest per year?
Jenny is paying $334.82 per year on credit card interest.
How much is she spending on credit card interest?We need to find his annual interest payment which is:
= $1100 * 2% * 12 month
= $264
So, we have an annual interest payment of $264
We must account for interest that accumulates on the interest itself. To calculate this, we can use the formula: A = P (1 + r/n)^(nt) when P is $264, r is 24%, n is 12 and t is 1.
A = $264 * (1 + 0.24/12)^(12*1)
A = $264 * 1.26824179456
A = $334.815833764
A = $334.82.

Find the 9th term.
Answer:
We can see that the sequence is formed by multiplying each term by 2 to obtain the next term. Therefore, the fourth term is 12 x 2 = 24, the fifth term is 24 x 2 = 48, and so on.
To find the ninth term, we can multiply the third term by 2 six times:
3 x 2^6 = 3 x 64 = 192
Therefore, the ninth term of the sequence is 192.

The displacement of the particle at time t is 11t - t², and the total distance traveled by the particle in 2 seconds is 9 meters.
The displacement of a particle moving along a straight line can be calculated by finding the area under the velocity-time graph. In this case, the velocity function is v(t) = 11 - 2t for 0 ≤ t ≤ 2.
To find the displacement at time t, we need to find the area under the velocity-time from t = 0 to t = t. The formula for displacement is the integral of the velocity function with respect to time:
s(t) = ∫v(t) dt = ∫(11 - 2t) dt = 11t - t²
Therefore, the displacement of the particle at time t is given by s(t) = 11t - t².
To find the total distance traveled by the particle in 2 seconds, we need to consider both the forward and backward motion. Since the velocity is decreasing at a constant rate of 2 m/s², the particle will come to rest at t = 11/2 seconds.
The total distance traveled by the particle in 2 seconds is given by:
d(2) = ∫|v(t)| dt = [tex]\int\limits^{11/2}_0[/tex] v(t) dt + [tex]\int\limits^2_{11/2}[/tex]|v(t)| dt from 11/2 to 2
= [[tex]\int\limits^{11/2}_0[/tex](11t - t²) ] + [[tex]\int\limits^2_{11/2}[/tex](-11t + t²) ]

11. if m < MPL =63 degrees, find each measure
The diameter of the circle is 16.04 cm.
The circumference is 50.39 cm
How to solve for the diameterA = πr²
where A is the area of the circle and r is its radius.
square both sides
r = √(A/π) = √(201.06/π) = 8.02 cm
The diameter of the circle is twice the radius, so we can find it by multiplying the radius by 2:
d = 2r = 2(8.02) = 16.04 cm
Therefore, the diameter of the circle is 16.04 cm.
To find the circumference of the circle, we can use the formula:
C = 2πr
where C is the circumference and r is the radius. We already know the value of the radius, so we can substitute it into the formula:

You would like to estimate the prevalence of a disease. You randomly sample 10 people from the population of interest and 4 of them have the condition. Using a Beta prior with αα and ββ both being 1010, what is the posterior mean prevalence closest to?
The required posterior mean prevalence is closest to 0.47.
We can use Bayes' theorem to find the posterior distribution of the prevalence parameter, given the data and the Beta prior:
posterior ∝ likelihood x prior
where the likelihood is given by the binomial distribution:
likelihood = P(observing 4 cases out of 10 | prevalence)
and the prior is a Beta distribution with parameters α = β = 10:
prior = Beta(α=10, β=10)
We can calculate the posterior distribution by multiplying the likelihood and prior, and then normalizing:
posterior = Beta(α=14, β=16)
where the posterior Beta distribution has parameters α=14 (10 + 4) and β=16 (10 + 10 - 4).
The posterior mean of a Beta distribution with parameters α and β is:
posterior mean = α / (α + β)
Plugging in the values of α and β from the posterior distribution, we get:
posterior mean = 14 / (14 + 16) = 0.467
