The standard deviation is used more frequently then the variance because standard deviation is more stable and less sensitive to outliers.
The Standard Deviation and Variance are defined as two closely related measures of the spread or dispersion of a set of data.
The Variance is defined as average of squared differences from mean, while Standard Deviation is square root of variance.
The reason why the standard deviation is used more frequently than variance is because the standard deviation is expressed in same units as the original data, whereas the variance is expressed in squared units.
For Example, if we measure heights of a group of people in inches, the standard deviation will be expressed in inches, whereas variance will be expressed in square inches.

Yes, measures of variability are used to describe the extent to which scores in a distribution differ from one another.
Measures of variability include the range, variance, and standard deviation, and they give us a sense of how spread out the scores in a distribution are. These measures help us understand the variability or dispersion of the data and how far the individual scores in a distribution deviate from the mean or other measures of central tendency.
Measures of central tendency, such as the mean, median, and mode, describe the central or typical value of a set of scores. They provide a summary of the data and a single value that represents the center of the distribution.
The decisions regarding graph size, shape, and style are usually based on the type of data being presented and the message being conveyed. A histogram, for example, may be used to visually display the distribution of a set of scores, and the size, shape, and style of the graph can be adjusted to highlight important features of the data.

Mrs. Townsend is giving you a test worth 100 points and it contains 40 questions. There are two-point and four-point questions on the test. How many of each type of question are on the test?
Answer:
[tex]10[/tex] four point questions and [tex]30[/tex] two point questions
Step-by-step explanation:
Let's say [tex]f =[/tex] [tex]\text{number of four point questions}[/tex] and[tex]t = \text{number of two point questions}[/tex]. The total number of questions is [tex]40[/tex], therefore [tex]t + f = 40[/tex]. We know the test is worth [tex]100[/tex] points so we can write [tex]2t + 4f = 100[/tex]. We have a system of equations: [tex]t + f = 40 \text{ and } 2t + 4f = 100[/tex]. We can rewrite [tex]t[/tex] as [tex]t = 40 - f[/tex]. We rewrite this in the equation [tex]2t + 4f = 100[/tex]. Since [tex]t = 40 - f[/tex], we have [tex]2 \cdot (40 - f) + 4f = 100[/tex]. Distributing & simplifying gives
[tex]2 \cdot (40 - f) + 4f = 100\\(80 - 2f) + 4f = 100,\\\text{Remove parentheses} 80 - 2f + 4f = 100,\\80 + (-2f) + 4f = 100\\80 + 2f = 100,\\\text{Subtract 80 from both sides} 2f = 20,\\\text{Divide 2 by both sides} f = 10.\\[/tex]
Since we determined [tex]t = 40 - f[/tex] and [tex]f = 10[/tex], subtracting [tex]10[/tex] from [tex]40[/tex] will give [tex]t = 30[/tex].
Therefore, there are [tex]10[/tex] four point questions and [tex]30[/tex] two point questions.

Joshua invested $97,000 in an account paying an interest rate of 6% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 8 years?
The required after 8 years, the investment will be worth approximately $156,753.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Here,
To calculate the future value of Joshua's investment after 8 years with an interest rate of 6% compounded daily, we can use the formula:
In this case, P = $97,000, r = 6% = 0.06, n = 365 (since the interest is compounded daily), and t = 8.
So, we have:
[tex]A = $97,000 \times (1 + 0.06/365)^{365 * 8}[/tex]
A = $195,239.00
Therefore, after 8 years, the investment will be worth approximately $156,753.

Which of the following represents the total area of the figure?
A. 222 cm2
B. 240 cm2
C. 258 cm2
D. 294 cm2
The total area of the composite figure is 258 squared centimeters.
What is the area of the composite figure?The figure in the diagram is composed of two triangle and a rectangle?
The area of a triangle = 1/2 × base × height
Area of a rectangle = length × width
From the diagram;
Triangle 1
base = 4cmheight = 12cmTriangle 2
base = 12cmheight = 3cmRectangle
length = 18cmwidth = 12cmTo find the area of the composite figure, we find the area of the two triangle and rectangle and add.
Area = area of triangle 1 + area of triangle 2 + area of rectangle.
Area = ( 1/2 × base × height ) + ( 1/2 × base × height ) + ( length × width )
Area = ( 1/2 × 4 × 12 ) + ( 1/2 × 12 × 3 ) + ( 18 × 12 )
Area = ( 2 × 12 ) + ( 6 × 3 ) + ( 18 × 12 )
Area = 24 + 18 + 216
Area = 258cm²
Therefore, the area is 258 squared centimeters.

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choose "down" as positive and ignore air friction, the function is h(t) = 36t^2 - 64.

A collegiate basketball player hits 80% of his free throw attempts. Assuming free throw attempts are independent, he will try 100 free throws this season the answers are as follows:
a) The mean of X is 80.
b) The standard deviation of X is 4.
c) The probability that the basketball player makes at least 90 of these attempts is approximately is 0.0062.
d) If the basketball player instead attempts only 10 free throws, the probability that he makes at most 4 of these is 0.0064.
As per the question given,
a) The mean of X is given by the formula: mean = n * p, where n is the number of trials and p is the probability of success on each trial. In this case, the player attempts 100 free throws with a probability of success of 0.8, so the mean is:
mean = 100 * 0.8 = 80
Therefore, the correct answer is 80.
b) The standard deviation of X is given by the formula: standard deviation = sqrt(n * p * (1 - p)). Substituting the values, we get:
standard deviation = sqrt(100 * 0.8 * 0.2) = 4
Therefore, the correct answer is 4.
c) To find the probability that the player makes at least 90 free throws, we can use the normal approximation to the binomial distribution. The mean is 80 and the standard deviation is 4, so we can standardize the value of X as follows:
z = (90 - 80) / 4 = 2.5
Using a standard normal distribution table, we can find the probability that Z is greater than 2.5, which is approximately 0.0062.
Therefore, the correct answer is 0.0062.
d) If the player attempts only 10 free throws, the number of successful attempts X follows a binomial distribution with n=10 and p=0.8. The probability that he makes at most 4 of these attempts is:
P(X <= 4) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4)
Using the binomial distribution formula, we can calculate each of these probabilities and sum them up. Alternatively, we can use a binomial probability table or a calculator to find the cumulative probability.
Using a binomial probability calculator, we get:
P(X <= 4) = 0.0064 (rounded to four decimal places)
Therefore, the correct answer is 0.0064.

By Using the Cumulative distributed Function(CDF)m we get:
a) P (x <= 3 ) = 0.36
b) P ( 2.5 <= x <= 3 ) = 0.11
c) P (x > 3.5 ) = 1 - 0.49 = 0.51

Given:
The cdf is as follows:
F(x) = 0 x < 0
F(x) = (x^2 / 25) 0 < x < 5
F(x) = 1 x > 5
Now,
a) Evaluate the CDF given with the limits 0 < x < 3.
So, P (x <= 3 ) = (x^2 / 25) | 0 to 3
P (x <= 3 ) = (3^2 / 25) - 0
P (x <= 3 ) = 0.36
b) Evaluate the CDF given with the limits 2.5 < x < 3.
So, P ( 2.5 <= x <= 3 ) = (x^2 / 25) | 2.5 to 3
P ( 2.5 <= x <= 3 ) = (3^2 / 25) - (2.5^2 / 25)
P ( 2.5 <= x <= 3 ) = 0.36 - 0.25 = 0.11
c) Evaluate the CDF given with the limits x > 3.5
So, P (x > 3.5 ) = 1 - P (x <= 3.5 )
P (x > 3.5 ) = 1 - (3.5^2 / 25) - 0
P (x > 3.5 ) = 1 - 0.49 = 0.51
d) The median checkout for the duration that is 50% of the probability:
So, P( x < a ) = 0.5
⇒ (x² / 25) = 0.5
⇒ x² = 12.5
⇒ x = 3.5355
e) The probability density function can be evaluated by taking the derivative of the cdf as follows:
pdf f(x) = d(F(x)) / dx = x / 12.5
f) The expected value of X can be evaluated by the following formula from limits - ∞ to +∞:
E(X) = integral ( x . f(x)).dx limits: - ∞ to +∞
E(X) = integral ( x² / 12.5)
E(X) = x³ / 37.5 limits: 0 to 5
E(X) = 5³ / 37.5 = 3.3333
g) The variance of X can be evaluated by the following formula from limits - ∞ to +∞:
Var(X) = integral ( x² . f(x)).dx - (E(X))^2 limits: - ∞ to +∞
Var(X) = integral ( x³ / 12.5).dx - (E(X))^2
Var(X) = x⁴/ 50 | - (3.3333)^2 limits: 0 to 5
Var(X) = 5⁴/ 50 - (3.3333)^2 = 13.8891

X=a+b+4 and a directly proportional to y squared , b is inversely proportional to y when y=2 x=18 when y=1 x=-3 find x when y=4
X = 11 when y = 4 when X=a+b+4 and a directly proportional to y squared , b is inversely proportional to y.
Given that a is directly proportional to y^2 and b is inversely proportional to y, we can write the following two relationships:
[tex]a = k * y^2[/tex]
[tex]b = m / y[/tex]
where k and m are constants. From the first equation, we can find the value of k when y = 2:
[tex]a = k * 2^2[/tex]
[tex]k = a / 4[/tex]
And from the second equation, we can find the value of m when y = 2:
[tex]b = m / 2[/tex]
[tex]m = 2b[/tex]
Substituting these values into the equation X = a + b + 4, we can find X when y = 2:
[tex]X = (k * 2^2) + (m / 2) + 4[/tex]
[tex]X = (a / 4) * 4 + 2b + 4[/tex]
[tex]X = a + 2b + 4[/tex]
[tex]X = 18[/tex]
We can now use the value of k and m to find X when y = 4:
[tex]X = (k * 4^2) + (m / 4) + 4[/tex]
[tex]X = (a / 4) * 16 + (2b) / 4 + 4[/tex]
[tex]X = 4a + 2b + 4[/tex]
Substituting the value of X = 18 when y = 2, we can solve for a and b:
18 = 4a + 2b + 4
14 = 4a + 2b
7 = 2a + b
Solving the system of equations for a and b, we find:
a = 5
b = 2
Finally, substituting these values into the equation X = a + b + 4, we can find X when y = 4:
X = (5) + (2) + 4
X = 11
Therefore, X = 11 when y = 4.

Find the area of an isosceles triangle whose one side is 10 cm greater than each of its equal sides and perimeter is 100 cm.
Answer:
the area of the isosceles triangle is approximately 104.49 cm^2.
Step-by-step explanation:
The perimeter of the triangle is 100 cm, so we can write an equation using the lengths of the sides:
x + x + (x + 10) = 100
3x + 10 = 100
3x = 90
x = 30
So the equal sides of the triangle have length 30 cm and the side that is 10 cm greater has length 40 cm.
To find the area of the triangle, we can use the formula for the area of an equilateral triangle:
Area = (sqrt(3) / 4) * (side length)^2
Area = (sqrt(3) / 4) * 30^2
Area = (sqrt(3) / 4) * 900
Area = (sqrt(3) / 4) * 30 * 30
Area = (sqrt(3) / 4) * 900
Area = (30 * sqrt(3)) / 2
Area = 45 sqrt(3)
a gambler has a fair coin and a two-headed coin in his pocket. he selects one of the coins at random; when he flips it, it shows heads. what is the probability that it is the fair coin?
The probability of selecting the fair coin when a gambler has both a fair coin and a two-headed coin in his pocket is 50%.
This is because, when he selects one of the coins at random, it is equally likely that he has chosen either the fair coin or the two-headed coin. If he flips the coin and it shows heads, then the probability that it is the fair coin is still 50%, because either coin could have been selected and both would show heads.This is an example of a classical probability problem, which is based on the law of equal chances. This law states that when an event has multiple possible outcomes, each of those outcomes is equally likely to occur. In this case, there are two possible coins that could have been chosen, so each coin has a 50% chance of being selected. This means that the probability of selecting the fair coin is 50%.This also applies to events that have multiple outcomes which are not equally likely. For example, if a gambler has a fair coin, a two-headed coin, and a three-headed coin in his pocket, the probability of selecting the fair coin is still 50%. This is because the gambler has an equal chance of selecting any of the coins, regardless.

Step-by-step explanation:
SST Grocery Store has a display of 12-ounce cans of soft drink in cases of 24. Each case
measures 16.00 inches by 10.75 inches by 5.00 inches. How many cubic inches are needed if 360
cases are on display?
OA 619,200 cubic inches
OB 309,600 cubic inches
OC 61,920 cubic inches
OD 123,840 cubic inches
The answer is 309,600 cubic inches, which is option B.
What is the volume?
Volume is the total amount of space inside a three-dimensional shape. Volume is measured in cubic units, such as “cubic inches” or in³.
Volume is the amount of space matter takes up. The matter is anything that has mass and takes up space. Volume is used to describe the size of an object.
The volume of each case is 16.00 inches * 10.75 inches * 5.00 inches = 880 cubic inches.
So, the volume of 360 cases is 360 * 880 cubic inches = 309,600 cubic inches.
Therefore, the answer is 309,600 cubic inches, which is option B.

Which choice is the explicit formula for the following geometric sequence?
0.3,-0.06, 0.012, -0.0024, 0.00048, ...
A. an=0.3(0.2)"
B. an=-0.2(0.3)(n-1)
C. an= -0.3(-0.2)(n-1)
D. an= -0.3(0.2)(n-1)
E. an = 0.3(-0.2)(n-1)
The formula for given sequence is aₙ = 0.3(-0.2)ⁿ⁻¹ i.e. E.
What exactly is a sequence?
A sequence is a collection of numbers that follows pattern. Olivia, for example, has been offered a position with a beginning monthly pay of $1000 and a yearly raise of $500. Can you figure out her monthly pay for the first three years? The prices will be $1000, $1500, and $2000. Note that Olivia's income over a number of years creates a sequence as they follow a pattern where the numbers increase by $500 each time.
Now,
Given sequence is 0.3,-0.06, 0.012, -0.0024, 0.00048, ...
Of all given options only E satisfies the given sequence because
for E
a₁=0.3*-0.2¹⁻¹
=0.3*1
=0.3
a₂=0.3*-0.2²⁻¹
=-0.3*0.2
=-0.006
a₃=0.3*-0.2³⁻¹
=0.3*0.04
=0.012
hence,
The formula for given sequence is aₙ = 0.3(-0.2)ⁿ⁻¹.
