Which polygon will always have 4-fold reflectional symmetry.

Answer:

Option (2)

Step-by-step explanation:

Steps to draw a perpendicular at a point lying on a segment;

1). Take a point on the segment at which the perpendicular is to be drawn.

2). Draw an arc from the point chosen on the segment which intersects the segment at the two different points.

3). Now mark two arcs from these points with the same radius intersecting each other on the same side of the segment.

4). Join the point of intersection of the arc with the point given on the line with straightedge.

Hence a perpendicular is drawn at a point of a segment.

These steps have been followed in option (2).

Option (2) will be the answer.

The test is proved that hypothesis that the population mean is atleast 3-miles per gallon.

A hypothesis is the proposed explanation for any kind of  phenomenon.

So here are the values of X  BAR i=2.4. S is 1.8.

Our sample n =100.

The null hypothesis here is that mu is greater than or equal to 3.

Against the alternative hypothesis that  is less than three. Now the calculated value for the test statistic is going to be the  equal to X bar is in (-)  knots. That's 2.4 -3. divided by S over  2^2 of end. So 1.8 divided by the square root of the  100 gives us negative 3.33. So we can refer to that box of the T distribution and we are  get the value. The p value for the test is going to be less than 0.5. Therefore we have the  strong evidence that the not hypothesis is going to be the  read checked it.  So  therefore we can reject to the  null hypothesis and then it can accept the alternative by the  hypothesis that  is less than three. Where it is  here is the mean of the population, the noting the average increase per gallon.

Step-by-step explanation:

It is true, that the most level of confidence used in creating confidence intervals is 90%.

What is confidence interval?

A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

Answer:

Here is the answer.

Step-by-step explanation:

To expand the expression (1-2p)^10 using the binomial expansion, we can apply the binomial theorem. The binomial theorem states that for any positive integer n:

(x + y)^n = C(n, 0) * x^n * y^0 + C(n, 1) * x^(n-1) * y^1 + C(n, 2) * x^(n-2) * y^2 + ... + C(n, n-1) * x^1 * y^(n-1) + C(n, n) * x^0 * y^n

where C(n, k) represents the binomial coefficient, given by C(n, k) = n! / (k! * (n-k)!).

In this case, we have (1-2p) as x and we want to expand it to the power of 10. Let's calculate the expansion:

(1-2p)^10 = C(10, 0) * (1)^10 * (-2p)^0 + C(10, 1) * (1)^9 * (-2p)^1 + C(10, 2) * (1)^8 * (-2p)^2 + ... + C(10, 9) * (1)^1 * (-2p)^9 + C(10, 10) * (1)^0 * (-2p)^10

Simplifying further:

(1-2p)^10 = 1 * 1 * 1 + C(10, 1) * 1 * (-2p) + C(10, 2) * 1 * (4p^2) + ... + C(10, 9) * 1 * (-512p^9) + C(10, 10) * 1 * (1024p^10)

Now we can calculate the binomial coefficients and simplify the expression:

(1-2p)^10 = 1 - 20p + 180p^2 - 960p^3 + 3360p^4 - 8064p^5 + 13312p^6 - 15360p^7 + 11520p^8 - 5120p^9 + 1024p^10

Therefore, the expansion of (1-2p)^10 using the binomial theorem is 1 - 20p + 180p^2 - 960p^3 + 3360p^4 - 8064p^5 + 13312p^6 - 15360p^7 + 11520p^8 - 5120p^9 + 1024p^10.

The arithmetic mean is 59.

What is arithmetic mean?

It is the sum of collection of numbers divided by the count of the numbers.

Conider AB is the nuber satisfying the condition. Hence,

\(10A+B=A+B+A\times B\\9A=A\times B\\\)

Since AB is a two digit number hence, \(A\neq 0\\\). Hence, divide both sides by \(A\).

\(9=B\)

Hence, B is 9 and A can take any value from 1 to 9.

Hence, numbers are 19, 29, 39, 49, 59, 69, 79, 89,99.

Now, calculate arithmetic mean as follows:

\(AM=\frac{Sum \ of \ numbes}{Count \ of \ numbers}\\=\frac{19+29+39+49+59+69+79+89+99}{9}\\=59\)

Hence, arithmetic mean of numbers is 59.

Total interest earned = $10

Total amount in account after 2 years = $220.

How we calculate interest?

Ivanna will earn $10 in total interest over 2 years.

The total amount in the account (including interest) will be $210.

To calculate the interest, we can use the formula: interest = principal x rate x time.

Using this formula, we get interest = $200 x 0.05 x 2 = $20.

Adding this to the initial amount of $200, we get a total of $210 in the account after 2 years.

Answer:

$100.00

Step-by-step explanation:

Compound interest is calculated by multiplying the initial loan amount, or principal, by the one plus the annual interest rate raised to the number of compound periods minus one. This will leave you with the total sum of the loan including compound interest.

The amount I have to pay back in full is approximately 100 dollars.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

The formula for compound interest compounded semi-annually is,

A = P(1 + (r/2)/100)²ⁿ. (two semi-annuals in one year)

Therefore, A = 95(1 + (5.2/2)/100)²ˣ¹.

A = 95(1 + 0.026)².

A = 95(1.026)².

A = 95×1.052676.

A = $100 approximately.

The perimeter of the rectangle is  32 feet.

Perimeter of the rectangle:

The perimeter of a rectangle is stated that the sum of all the sides of a rectangle.

Through the definition, the perimeter of a rectangle,

P = 2 (a + b) units

where

“a” is the length of the rectangle

“b” is the width of the rectangle

Given,

Here we have the diagram of the rectangle and the measurements are given in it.

And we need to find the perimeter of the rectangle.

Through the given diagram, we know that, the values of

length = 12 feet

width = 4 feet

Now, we have to apply the values on the formula in order to solve it,

So, the perimeter is,

P = 2 ( 12 + 4)

When we simplify it then we get,

P = 2 (16)

After the multiplication we get the result as

P = 32 feet.

The parabola opens upward, the range of the function is [6/5, ∞) in interval notation.

We can find the range of the function by finding the vertex of the parabola, which will give us the minimum value, and then noting that the function increases without bound as x approaches infinity.

First, we need to find the vertex of the parabola. We can do this by finding the x-coordinate of the vertex, which is given by:

x = -b/2a

where a = 5, b = -2. Substituting these values, we get:

x = -(-2)/(2(5)) = 2/5

To find the y-coordinate of the vertex, we can substitute this value of x into the equation for g(x):

g(2/5) = 5(2/5)^2 - 2(2/5) + 1 = 5/5 - 4/5 + 1 = 6/5

So the vertex of the parabola is (2/5, 6/5), which is the minimum value of the function.

Since the parabola opens upward, the range of the function is [6/5, ∞) in interval notation.
