The sum of an infinite geometric series is given by a+ar+ar^2  where a is the first term and r is the common ratio.

The sum of the series  can be represented by :

a / ( 1 - r)  = 12

a = 12 ( 1- r )    (1)

So....note that the sum of the  terms  with odd powers of r  can be represented by :

ar  + ar^3  + ar^5 + ar^7 +  ..... + ar^(2n - 1)  =  5   (2)

And note that the sum of the  terms  with even powers of r  can be represented by :

a  +  ar^2  + ar^4 + ar^6 + ar^8 +  ..... + ar^(2n)  =  7   (3)

Multiply (2)  by r on both sides

ar^2  + ar^4  + ar^6 + ar^8 +  ..... + ar^(2n )  =  5r     (4)

Subtract   (4)  from (3)

a  = 7 - 5r    (5)

Sub (5)  into (1)

7 - 5r  = 12(1 - r)

7 - 5r  =  12 - 12r

7r = 5     →   r  =  5/7

Check

a = 7 - 5(5/7)  =  24/7

A prism is an optical element that is transparent and has flat, polished surfaces used to refract light in physics (optics). The prism has two different formulas. A prism has a surface area of (2BaseArea) + Lateral Surface Area. Prism volume equals Base Area + Height.

So, to calculate the volume of a cube or rectangular prism, multiply the area of the corresponding shape by the length. which results in the equation V=bhl.

\(V_{rectangular prism} =L*B*H\)

Suppose,

V=200\(cm^3\)

L=2W

rewrite the volume formula by making substitutions for V and L

V     =     L·W·H

make the substitution

200 \(cm^3\)   =    (2W)·W·H

simplify

200 \(cm^3\) =2\(W^2\)H

rewrite the equation as H in terms of W... write H(W) or height as a function of width

use algebra to solve the volume formula for H (instead of V)

\(H=\frac{200 cm^3}{2W^2}\)

Answer:

Step-by-step explanation:

Decay is getting smaller, and c is the only one where B will reduce the size of something.

The value of k that makes the line passing through the points (k, 3) and (6, k) have a slope of 2 is k = 5

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

A line with a slope of 2 passes through the points (k, 3) and (6, k), hence:

2 = (k - 3) / (6 - k)

12 - 2k = k - 3

k = 5

A cutoff of 10% for statistical significance is more lenient compared to the standard 5% cutoff.

What is statistical significance?

Statistical significance is a measure used in hypothesis testing to determine whether an observed result is likely to be due to chance or represents a true effect. It indicates the level of confidence that can be placed in the findings of a study or experiment

Compared to the standard 5% cutoff for statistical significance, a cutoff of 10% would be more lenient or less strict.

In statistical hypothesis testing, the significance level, often denoted as alpha (α), represents the threshold below which the p-value must fall to reject the null hypothesis. The commonly used standard cutoff is 5% (or 0.05), which means that if the p-value is less than 0.05, the result is considered statistically significant, and the null hypothesis is rejected.

When the cutoff is increased to 10% (or 0.10), it means that the threshold for statistical significance is relaxed. In other words, a p-value less than 0.10 would now be considered statistically significant, leading to a higher likelihood of rejecting the null hypothesis. This increased cutoff allows for a wider range of p-values to be considered statistically significant, making it easier to detect effects or relationships.

However, it's important to note that a higher cutoff also increases the chances of a Type I error (rejecting the null hypothesis when it is true). This means there is a higher probability of falsely concluding that there is a significant effect or relationship when it may not actually exist.

Choosing the appropriate significance level depends on the specific context, research field, and the consequences of Type I and Type II errors. Lower significance levels, like 5%, are often used to maintain a more stringent standard and reduce the risk of false positives. However, in certain cases, a higher cutoff like 10% may be suitable, such as in exploratory analyses or when the consequences of Type II errors (failing to detect a true effect) are more severe.

Step-by-step explanation:

The radius of the circle is approximately 10.17 units (rounded to two decimal places).

To find the radius of the circle, we need to use the formula that relates the central angle to the length of the arc and the radius of the circle. The formula is given as:

arc length = radius x central angle

In this case, the arc length is given as 24.4 and the central angle is given as 2.4 radians. Substituting these values in the formula, we get:

24.4 = r x 2.4

Solving for r, we get:

r = 24.4 / 2.4

r ≈ 10.17

Answer:  The total number of colored papers is 18.

Step-by-step explanation:

Given: The ratio of coloured papers to wight papers is 3:8.

Let total number of colored papers = 3x

and total number of wight papers = 8x

Since, there are 48 wight papers , then

\(8x=48\)

\(\Rightarrow\ x=6\)

Now , number of colored papers = 3(6)=18

Hence, the total number of colored papers is 18.

unit cost in dollars per mile

Step-by-step explanation:

You are given cost, miles, and time for a certain trip.

You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.

$7.20/(12 miles) = $0.60/mile

$0.60/mile * 46 miles = $27.60

By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.

Answer:

T = 1/60

T = 0.016 s

Hence,

Time period is 0.016 s

\( \sf \: T= \frac{1}{F} \)

This is the basic formula, You can use this formula to solve similar problems. Remember that whenever Frequency is given and we have to find time period this formula will be applied!~
