The 95% two-sided confidence interval for the mean is (-0.1,0.2). one of your friends claims that the mean could be 0. is your friend's claim reasonable.

It is TRUE statement.

Now, According to the question:

Let's know:

What is meant by 95% confidence interval?

Strictly speaking a 95% confidence interval means that if we were to take 100 different samples and compute a 95% confidence interval for each sample, then approximately 95 of the 100 confidence intervals will contain the true mean value (μ).

                                                      OR

A confidence interval, in statistics, refers to the probability that a population parameter will fall between a set of values for a certain proportion of times. Analysts often use confidence intervals than contain either 95% or 99% of expected observations.

Hence, The 95% two-sided confidence interval for the mean is (-0.1,0.2). one of your friends claims that the mean could be 0. is your friend's claim reasonable.

In equilateral triangle ABC, the length of side A is equal to the side B and side C.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane. Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The sum of the triangle's three angles equals 180 degrees.

The probability of getting exactly 4 heads is 0.26

A loaded coin has 0.48 probability of coming up heads

0.52 probability of coming up tails.

coin is flipped 7 times

let's assume n = 7.

The seven flips of the coin are separate from one another, so what happens on one flip is unaffected by the outcomes of the other tosses.

When calculating the likelihood that two events will occur simultaneously, we must multiply the probabilities of events 1 and 2, presuming that event 1 occurred.

Tosses never affect one another, so the "assuming event 1 happened" part is no longer necessary because it has no effect on the probability. As a result, we just need to multiply the chances for each toss. This supposition is essential. We would have needed to know exactly how tosses are dependent on one another if they were interdependent.

Typically, we would have [tex](n! /(r!)*(n - r)!)*p^r*(1-p)^(n-r)[/tex] is the probability of getting r heads out of n, without taking into account the order.

probability of getting exactly 4 heads r = 4.

7!/(4!*3!)   = 35

Answer: 12 miles

Step-by-step explanation:

Let y represent the cost and x represent the number of miles!

y = 1.25x + 3

Now put the $18 in for y

18= 1.25x + 3

15 = 1.25x

x = 12 miles

Answer:

Step-by-step explanation:

We can model the cost of a taxi trip with y = 1.25x + 3, where y is the total cost and x is the miles traveled. $1.25 is charged per mile, and the initial $3 is added to find the total cost. We know that the total cost is $18, so we can put 18 in for y and solve for x:

18 = 1.25x + 3

15 = 1.25x (subtracted 3 from both sides)

12 = x (divided each side by 1.25)

So, the trip was 12 miles

The given pair of equations has no solution.

Two equations can be solved through three different methods:

Let's use the elimination method in this question

                          10x - 2y = 6      .....(II)

Multiply (II) by 2

                          20x - 4y = 6      .....(II)

Now, subtracting equations (I) and (II) we will get no solution.

It is possible for the two lines to be parallel and not intersect. In this situation, we cannot identify a shared point between the two, and as a result, the system of the two equations representing the two lines cannot provide a solution!

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the Equation: x² - 10x-13 = 0

Now, half the coefficient of x and add and subtract the square of the half of the coefficient of x.

So, x² - 10x-13 = 0

x² - 10x-13 -5² + 5² = 0

The straight line that "just touches" the curve at a particular location is known as the tangent line (or simply tangent) to a plane curve in geometry. It was described by Leibniz as the path connecting two points on a curve that are infinitely near together.  A straight line has a slope of f'(c), where f' is the derivative of f, and is said to be tangent to a curve at a point x = c if it passes through the point (c, f(c)) on the curve. Space curves and curves in n-dimensional Euclidean space have a similar definition.

The Maclaurin series expansion of f(x) = 1/(1-x)² is

1 + 2x + 6x² + 24x³ +......

The general expression for the Maclaurin series is given by the formula:

f(x) = f(0) + xf'(0) + x²f''(0) + ..... + xⁿf⁽ⁿ⁾(0)+...

= ∑ f⁽ⁿ⁾ (0)xⁿ/n!

n= 0 to infinity

Specifying the convergence region completes the Maclaurin series formulation. Detailed five steps for determining the Maclaurin series of

f(x) = 1/(1-x)²

Step 1 : Find Derivatives for f(x)

f(x) = 1/(1-x)²

f'(x) = -2(1-x)⁽⁻²⁻¹⁾ (-1) = 2/(1-x)³

The second derivative of f(x) is the derivative of f''(x) :

f"(x) = 2(-3)(1-x)⁽⁻³⁻¹⁾(-1) = 6/(1-x)⁴

Differentiating again, f"'(x) = 6(-4)(1-x)⁽⁻⁴⁻¹⁾(-1)

= 24/(1-x)⁵

Thus, the nᵗʰ derivative is ,

f⁽ⁿ⁾(x) = (n+1)!/(1-x)⁽ⁿ⁻¹⁾

Step 2: Evaluate These Derivatives and f(x) at x=0 let x = 0 , f(0) = 1

f'(0) = 2 , f"(0) = 6 , ....... , f⁽ⁿ⁾(0) = (n+1)!

Step 3 : Now, the Sum of Products :

f(x) = f(0) + xf'(0) + x²f''(0) + ..... + xⁿf⁽ⁿ⁾(0)+...

xf'(0) = 2x

x²f"(0) = 6x²

x³f"'(0) = 24 x³

----------------------------

xⁿf⁽ⁿ⁾(0)= (n+1)!

Thus, the Maclaurin series for ln(1 + x) is this:

the surface area is

base area (49 in²) + 4×side triangle area = 185 in².

one of these 4 side triangle area is

A pentagon is a 2D polygon with five sides and five angles. The word "pentagon" is created by combining the Greek words "penta" (which means "five") and "gon," which means "angles."

The President and the Secretary of Defense have exercised global command and control over the nation's armed forces from the Pentagon. Since its construction, the Pentagon has served as a national and international emblem. It is, above all, a metaphor for American strength and influence, with all the positive and negative connotations that entails.

Similar figures' surfaces have an area that is proportional to the square of their sides.

The ratio of the sides is on the left, and the ratio of their areas is on the right, therefore we may write this as a proportion.

Keep in mind that the ratio of the sides is squared because we are working with areas.

3b⁵ + 15b⁴- 18b⁷

= 3b⁵(1 + 5b - 6b²)

Hence, the given polynomial can be factorized as 3b⁵(1 + 5b - 6b²).

The standard error for the estimate of the proportion of all persons aged 65 and over with osteoarthritis is 0.0092.

The subset chosen from the larger set to make assumptions is known as a random sample. Standard Error can be defined as the term that measures the accuracy of the sample distribution which represents the population.

We know that,

                   Standard Error   =   √ ( P ( 1 - P ) / n )    → 1

As per the given question,

Substitute the values in 1,

Standard Error ( SE )   =   √ ( P ( 1 - P ) / n )

                                    =   √ ( 0.115 ( 1 - 0.115 ) / 1200 )

                                    =   √ ( 0.115 ( 0.885 ) / 1200 )

                                    =   √ ( 0.101775 / 1200 )

                                    =   √ ( 0.0000848125)

Standard Error ( SE )   =   0.0092093702   ≅   0.0092

Therefore, 0.0092 is the standard error for the estimate of the proportion of all persons aged 65 and over with osteoarthritis.

They both make 3 baskets. The number of points Norma and vincent have after first time out are 6 points and 9 points respectively

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.

If the number of basket is x, and the total point is y, thus

for Norma, the total point = 19+2x=y equation 1

for vincent, the total point = 16+3x= y equation 2

subtract equation 1 from 2

16-19+3x-2x = 0

-3+x = 0

x= 3

substitute 3 for x in equation 1

19+2(3)= y

25= y

y = 25

therefore they both made 3 basket after the first time out and Norma make extra 6 points and Vincent made extra 9 points
