The least number of terms required to compute pi as 3.14 is approx 400.

The series is π = 4 - 4/3 + 4/5 - 4/7 + .................

We have to determine the least number of terms required to compute pi as 3.14.

We can write the series as

π = 4(1 - 1/3 + 1/5 - 1/7 + .................)

The general equation of this series is

π = 4[tex]\Sigma_{k=0}^{\infty}(-1)^k(2k+1)^{-1}[/tex]

Now let S = π. So

S = 4[tex]\Sigma_{k=0}^{\infty}(-1)^k(2k+1)^{-1}[/tex]

From the Alternating series theorem

|S - S(n)| ≤ 4/(2n+1)

Hence, the accuracy should be

4/(2n+1) ≤ 1/2 × 10^{-2}

Multiply by 2 on both side, we get

8/(2n+1) ≤ 10^{-2}

We can write 10^{-2} as 1/100. Now the expression is

8/(2n+1) ≤ 1/100

Multiply by 100 on both side, we get

800/(2n+1) ≤ 1

Multiply by 2n+1 on both side, we get

800 ≤ 2n+1

Subtract 1 on both side, we get

2n ≥ 799

Divide by 2 on both side, we get

n ≥ 399.5

Hence, approx 400 terms need to compute pi as 3.14.

The Spearman-Brown formula is used to adjust the reliability estimate of a test when concerns arise about the shortness of the test, i.e., the limited number of test items. Thus, B is correct.

The formula takes into account the number of items in the test and calculates the expected increase in reliability if the test were to be made longer. The formula is based on the assumption that adding more items to a test would increase its reliability, and thus provides a way to estimate the theoretical minimum length of a test required to achieve a desired level of reliability.

The formula is widely used in psychological testing and educational measurement to evaluate the reliability of test scores and to make decisions about the number of items needed in a test to achieve a desired level of reliability.

The final cost of 1 sweatshirt, 2 T shirts, and 1 pair of pants would be $70.

The final cost of 1 sweatshirt, 2 T shirts, and 1 pair of pants can be represented by the following formula:

Final Cost = Sweatshirt Cost + (2 x T Shirt Cost) + Pants Cost

For example, if the cost of a sweatshirt is $20, the cost of a T shirt is $10, and the cost of a pair of pants is $30, the final cost of 1 sweatshirt, 2 T shirts, and 1 pair of pants would be:

Final Cost = $20 + (2 x $10) + $30

Avery write an explicit equation is  t(n)=19+(n-1)*(-2)=21-2n and a  Collin write a recursive equation is t(n+1)=t(n)/6-10/3.

What is explicit equation & recursive equation?

A closed-form expression or a mathematical expression expressed in terms of a limited set of well-known functions are examples of explicit formulas. the mathematical formula expressed analytically, using a limited or infinite number of well-known functions.

A recursive function is one that generates a series of phrases by repeating or using its own prior term as input. The arithmetic-geometric sequence, which has words with a common difference between them, is typically the basis on which we learn about this function.

To write an explicit equation, we can use the given recursive equation and find the value of the first term, t(1).

Substituting n=1 into t(n+1)=t(n)−2

gives t(2)=t(1)−2.

We know that t(2)=19, so t(1)=19+2=21.

Thus, the explicit equation for the sequence is t(n)=19+(n-1)*(-2)=21-2n. This is an arithmetic sequence.

To write a recursive equation, we can use the explicit equation that Avery wrote, t(n)=6n+8.

Rearranging this equation gives n=(t(n)-8)/6.

Substituting this expression into the recursive equation t(n+1)=t(n)−2 gives t(n+1)=(t(n)-8)/6−2.

Expanding t(n) on the right-hand side and simplifying gives t(n+1)=t(n)/6-10/3.

A explicit equation is  t(n)=19+(n-1)*(-2)=21-2n and a recursive equation is t(n+1)=t(n)/6-10/3.

The adult male foot length of 24.2 cm is significantly low as it falls outside of the range of 26.10 cm to 28.72 cm.

The range is just the difference between the greatest and smallest data points in a set.

The square root of the variance is the standard deviation.

The standard deviation measures how far apart the data is from the mean.

The range is a less useful measure of variance than the standard deviation.

The range of data is a measure of variance that indicates the difference between the dataset's maximum and least observation.

It is based only on two observations, the maximum and minimum.

The range rule of thumb states that approximately 68% of the data falls within one standard deviation of the mean, and approximately 95% of the data falls within two standard deviations of the mean.

So, the lower limit separating significantly low values will be:

27.41 - 1.31 = 26.10 cm

And the upper limit separating significantly high values will be:

27.41 + 1.31 = 28.72 cm.

To travel downstream, a boat needs 2 hours while to travel back upstream, it needs 4 hours. The river flows at speed of 3.58  3.58 km/hour

The relation between distance and speed is given by:

distance = speed x travelled time

In the problem, let:

vb = boat speed

v = river speed

Then, when the boat travels downstream:

28.62 = (vb + v) x 2

2vb + 2v = 28.62   ... (Equation 1)

When the boat travels upstream:

28.62 = (vb - v) x 4

Divide both sides by 2:

14.31 = (vb - v) x 2

2vb - 2v = 14.31  ... (Equation 2)

Substract equation 1 by equation 2

2vb + 2v = 28.62

2vb  - 2v = 14.31 _

Because when three principles are not linearly related, a unique plane composite triangle in Geometric shapes are discovered. Triangles are polygons because they have three sections and three corners. The points where it three sides of the triangle converge are referred to as the triangle's corners. Three triangle angles are multiplied to yield 180 degrees.

"15 + r" is the expression that represents the total number of rows knitted by Christine. Thus, option B is correct.

To find the total number of rows Christine has knit, we need to add the number of rows she knit over the weekend (represented by the variable "r") to the number of rows she had already knit (15).

This can be done by using the expression:

This expression states that the total number of rows is equal to the initial number of rows (15) plus the additional rows knit over the weekend (represented by the variable "r"). The value of "r" could be any number, so the expression "15 + r" could represent any total number of rows.
