if the sum of the first three terms of a GP is half it's sum to infinity. find it's positive common ratio.

**Answer:**

See below

**Step-by-step explanation:**

Sum of n = inf = a / ( 1-r) one half of this = 1/2 ( a/(1-r) )

Sum of first 3 terms = a ( 1- r^n) / ( 1-r) = a (1-r^3) / (1-r)

The underlined value are equal ( given in the Q)

1/2 a / (1-r) = a ( 1-r^3) / (1-r) Multiply both side by ( (1-r) )

1/2 a = a ( 1-r^3) divide both sides by a

1/2 = 1- r^3 subtract 1 from both sides

-1/2 = - r^3

1/2 = r ^3

r = cuberoot ( 1/2) = ** 1/2 ^(1/3) = .793700526**

Which of the following lists of data has the largest standard deviation? Hint: you should not need to compute the standard deviation for each list.Select the correct answer below:22, 25, 25, 22, 25, 23, 24, 23, 26, 2413, 11, 11, 11, 10, 14, 14, 10, 11, 1116, 14, 15, 15, 16, 16, 15, 16, 18, 1425, 23, 25, 22, 21, 25, 22, 21, 25, 237, 14, 19, 18, 4, 16, 5, 11, 11, 12

**Answer:**

7, 14, 19, 18, 4, 16, 5, 11, 11, 12

**Explanation: **

The standard deviation is a statistic that measures the spread of a dataset relative to its mean.

From the given options, find the range in each of them:

[tex]Range=Highest\;Value-Lowest\;Value[/tex]• Option 1: Range = 26-22=4

,• Option 2: Range=14-10=4

,• Option 3: Range=18-14=4

,• Option 4: Range = 25-21=4

,• Option 5: Range = 19-4=15

We see that the dataset in Option 5 has a far greater range and thus the dataset will have the biggest spread relative to its mean.

**Option 5 has the largest standard deviation.**

1. A piece of power transmission equipment is being designed. The design includesa set of three different meshed gears with a total of 107 teeth between them. If thesecond gear has 13 more teeth than the first gear. The third gear has 15 more teeththan the second gear.How many teeth does the second gear have?

[tex]x+y+z=107[/tex]

where x is the first, y the second and z the third

*the second gear has 13 more teeth than the first gear*

*The third gear has 15 more teeth than the second gear*

we need solve z form the third equation and solve x from the second equation an replace on the first

[tex]\begin{gathered} z=y+15 \\ x=y-13 \end{gathered}[/tex]replacing

[tex]\begin{gathered} (y-13)+y+(y+15)=107 \\ y-13+y+y+15=107 \\ 3y+2=107 \\ 3y=105 \\ y=35 \end{gathered}[/tex]so, the second gear have 35 teeth

Roseanne makes 1 1/2 of strawberry lemonade. She pours 1/4 of a liter of lemonade into a thermos to take to the park. Her brother drinks 2/5 of the remaining lemonade. How much lemonade does Roseanne's brother drink? Which expression can be used to determine the amount of lemonade Roseanne's brother drank? A. 1 1/2 - (1/4 x 2/5) B. (1 1/2 + 1/4) x 2/5 C. (1 1/2 - 1/4) x 2/5 D. (1 1/2 - 1/4) ÷ 2/5

we know that

the total lemonade is 1 1/2 liter

She pours 1/4 of a liter of lemonade into a thermos

Her brother drinks 2/5 of the remaining lemonade

the remaining lemonade is equal to

1 1/2-1/4=3/2-1/4=5/4 liters

Multiply by 2/5

(5/4)(2/5)=10/20=1/2 liter

therefore

answer is option

**C. (1 1/2 - 1/4) x 2/5**

A native wolf species has been reintroduced into a national forest. Originally 200 wolves were transplanted. After 3 years, the population had grown to 270 wolves. If the population grows exponentially, then at what annual rate is the population growing? Round the answer to the nearest tenth of a percent.

**The population is growing at an annual rate of 16.2%**

Ainsley had 3 yards of string. She used 1/4 yard for a project. She wants to divide the rest into pieces 5/6 yard long. How many pieces can she make?

She can make 3.3 **pieces **from the **remaining **length

From the question, the given parameters are:

Length of string = 3 yardsAmount used for project = 1/4 yardLength of each piece = 5/6 yardWe start by calculating the **length **of the remaining **pieces **as a whole

This is calculated as

Length of remaining piece + length used for project = Length of string

Substitute the known values in the above **equation**

So, we have

Length of remaining piece + 1/4 yard = 3 yards

Subtract 1/4 from both sides

Length of remaining piece = 2.75 yards

The **number **of **pieces **is then calculated as

Pieces = Length of remaining pieces/Length of each piece

This gives

Pieces = 2.75 yards/(5/6 yards)

Evaluate the quotient

Pieces = 3.3

Hence, the number of **pieces **she can make is 3.3

The half life of iron-59 is 44.5 days. How much of

a 50g sample would remain after 178 days?

**Answer:**

If the half-life of a nuclide is 44.5 days, then 178 days is four half-lives.

**explanation:**

After four half-lives, 0.0625 (0.54) of the original nuclides remains. If 50g is the original mass, then the mass after 4 half-lives is 3.125g.

AT = A0 2(-T/H)

Angle IJL is 54 because **congruent angles** have equal measure.

**What are congruent angles?**

**Congruent angles** are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other. The type of angles does not make any difference in the **congruence of angles**, which means they can be acute, obtuse, exterior, or interior angles.

According to question, angle m IKL = 54

And AB// CD and EF// GH

Angle IKL is alternate **interior angle** to angle HLK

m angle HLK= m angle IKL (**congruent angles** have equal measure)

m angle HLK= 54

Similarly, m angle IJL = m angle HLK

**What is Integer ?**

An **integer** is a whole number from the set of -ve , non-negative , +ve and 0 numbers.

Let's see how both the option is correct

we know, **integers** are 0,1, 2, 3, .... or -1, -2 , -3 ......

Means the number which is **not** in fraction or decimal value or root.

so, by seeing option(a) we can say it's an **integer**

but in option(b) it's the root so how it is **integer**

The answer is simple it's **perfect square** of 12 so √144 = 12 so that means it have the value which is **not** in fraction. By that we can say that **option(b) **is also an **integer**

Now, in option(c) and (d) they are **not** the perfect square and their root results in decimal values. so we cannot tell them as an **integer** value.

Emery borrowed money from her brother to buy a new phone and is paying off a fixed amount each week. After 2 weeks, she will owe $456, and after 5 weeks, she will owe $228.

a. What was the original amount Emery borrowed?

b. How much does she pay each week?

c. How useful are equations in point-slope and slope-intercept forms for answering each question?

The $456 and $228 Emery **owed **from the amount she **borrowed** to **buy** a new **phone** after 2 **weeks** and 5 weeks gives;

a. The original amount owed is $608

b. Emery pays $76 each week

c. The point and slope and slope and intercept both gives the amount Emery pays each week as the slope, while the slope and intercept form further gives the original amount borrowed as the y–intercept, *c*

A **straight line equation** is one which expresses a **linear** **relationship** between variables

Let y represent the **original amount** of **money** Emery borrowed from her brother, and let *m* represent the **amount** she pays each week to settle the **loan**, we have;

The given parameters are;

The amount Emery owes after 2 weeks = $456

The amount Emery will owe after 5 weeks = $228

a. The above information can be expressed by writing the following equations;

456 = y - 2•m...(1)

228 = y - 5•m...(2)

Subtracting equation (2) from equation (1) gives;

y - 2•m - (y - 5•m) = 456 - 228 = 228

3•m = 228

Therefore;

m = 228 ÷ 3 = 76

m = 76

The original amount Emery borrowed, *y*, from equation (1) is therefore;

y = 456 + 2•m

y = 456 + 2 × 76 = 608

The original amount Emery borrowed, *y*, is $608

b. The amount Emery pays each week, *m** *= $76

c. The straight line equation in **point** and **slope** **form** is presented as follows;

[tex] y_2 - y_1 = m•(x_2 - x_1) [/tex]

From the above equation, the two points (456, 2) and (228, 5) given in the question can be used to find the slope, *m*, which is the amount paid each month

The slope and intercept form of a straight line equation is *y *= m•x + c

From the slope and intercept form, we have;

The slope, *m *= The amount Emery pays per month

The intercept, *c *= The original amount Emery borrowed

Therefore, both forms of the straight line equation gives the amount Emery pays each week, while the slope and intercept form also gives the original amount Emery borrowed
