Answer:

  f(n) = 5n(n -1)/2 +9

Step-by-step explanation:

The rule will depend on what kind of sequence you think this is. An infinite number of rules can be dreamed up that will give these three values.

The simplest polynomial rule is one of 2nd degree. We know this because the first differences are 14-9 = 5 and 24-14 = 10, so are not constant. Only three values are given, so only a polynomial of degree 3-1=2 can be specified by these points.

If we say the polynomial is ...

  f(n) = an^2 +bn +c

Then the three given points give rise to three equations:

  9 = a + b + c

  14 = 4a +2b +c

  24 = 9a +3b +c

Solving these by your favorite method gives ...

  a = 5/2, b = -5/2, c = 9

So an explicit polynomial rule can be written as ...

  f(n) = 5n(n -1)/2 +9

_____

Additional comment

A sequence such as this one can also be described by an exponential rule. Here's one that describes these points:

  f(n) = 5·2^(n-1) +4

The fact that the first differences (5, 10) are related by a factor of 2 suggests 2 as the base of the exponent.

Answer:

a) About 68% of the data would be between 305 grams to 395 grams

b) About 95% of organs weighs between 260 grams and 440 ​grams

c)About 5% of organs weighs less than 260 grams or more than 440 ​grams

d) About 97% of organs weighs between 215 grams and 440 ​grams

Step-by-step explanation:

The empirical rule formula:

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

​(a) About 68​% of organs will be between what​ weights?

We would be applying the First rule of the Empirical formula to this.

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

Mean = 350 grams

Standard deviation = 45 grams

Hence,

350 grams - 45 grams

= 305 grams

350grams + 45grams

= 395 grams

Therefore about 68% of the data would be between 305 grams to 395 grams

​(b) What percentage of organs weighs between 260 grams and 440 ​grams?

Let try the second rule

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

Mean = 350 grams

Standard deviation = 45 grams

μ - 2σ

= 350 - 2(45)

= 350 - 90

= 260

μ + 2σ

= 350 + 2(45)

= 350 + 90

= 440

Therefore, about 95% of organs weighs between 260 grams and 440 ​grams

​(c) What percentage of organs weighs less than 260 grams or more than 440 ​grams? ​

Let try the second rule

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

Mean = 350 grams

Standard deviation = 45 grams

μ + 2σ

= 350 - 2(45)

= 350 - 90

= 260

μ + 2σ

= 350 + 2(45)

= 350 + 90

= 440

Since, about 95% of organs weighs between 260 grams and 440 ​grams, the percentage of organs weighs less than 260 grams or more than 440 ​grams is calculated as:

100% - 95%

= 5%

Therefore, percentage of organs weighs less than 260 grams or more than 440 ​grams is 5%

(d) What percentage of organs weighs between 215 grams and 440 ​grams?

For 215 grams, we apply the 3rd rule to confirm

= 3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

Mean = 350 grams

Standard deviation = 45 grams

μ - 3σ

= 350 - 3(45)

= 350 - 135

= 215.

Hence, 99% of the organs weigh 215 grams

For 440, from the solve questions above, we know the second rule applies.

Hence,

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

Mean = 350 grams

Standard deviation = 45 grams

μ + 2σ

= 350 + 2(45)

= 350 + 90

= 440

Hence,

99% + 95%/ 2

= 194% / 2

= 97%

Therefore, about 97% of organs weighs between 215 grams and 440 ​grams

Answer:

a) 90th percentile

b) X = 51.43 ( Sophia's height ) , Amy's height = 50.92

c)  0.2394

d)  46.44 inches

Step-by-step explanation:

mean value( u ) = 47.7 inches

std ( σ )= 2.4 inches

Amy height = 1.34 std above mean value

Sophia height = 94th percentile of height distribution

A ) what percentile is Amy's height

To Calculate the percentile of Amy's height

P( X ≤  50.916   ) = P( (X-µ)/σ )  ≤  (50.916-47.7) /2.4)  

=P(Z ≤  1.340  ) = 0.9099  = 90th percentile

B) How Amy's height compare to Sophia's

The proportion given based on Sophia's height = 0.94

z -value at the proportion ( 0.94 ) = 1.55 ( from excel )

note z-value can be calculated using  =  ( x - µ ) / σ                      

therefore: X (Sophia's height )  = zσ + µ=   (1.55 * 2.4)  +  47.7  

 X = 51.43 ( Sophia's height ) , Amy's height = 50.92

C) percentage expected to be taller than 49.4 inches

P ( X ≥ 49.40  ) = P( (X-µ)/σ)  ≥ (49.4-47.7) / 2.4)              

= P(Z ≥ 0.708 )

= P( Z <  -0.708   )

= 0.2394

D) Below what height are the shortest 30% of 7-year old girls

( u ) = 47.7 inches

std ( σ )= 2.4 inches

given proportion = 30% = 0.3

The z value at 0.3 = -0.52 ( from excel )

to calculate for X ( height ) we have to apply the formula used to determine z value

z= (x-µ) /σ

hence : X = (Z * σ)  + u = (-0.52 * 2.4 ) + 47.7

            X = 46.44

below 46.44 inches lies about 30% of 7 year old girls height

Answer:

135 billion, or 135,000,000,000

Step-by-step explanation:

The 4 in 134 represents the number of billions.  Since the next digit (6) is greater than 5, we must round up, obtaining

135 billion, or 135,000,000,000

When we round off the given number to the billions place, we get -  135,000,000,000.

Rounding off means a number is made simpler by keeping its value intact but closer to the next number.

Given is a number as 134,642,358,000

For rounding of the number to the billions place, first we will have to find the digit representing the billions place. The digit 4 represent the billions place. So we have to round up till digit 4. We can write the rounded number as -  135,000,000,000

Therefore, when we round off the given number to the billions place, we get -  135,000,000,000.

EG = 16

Step-by-step explanation:

Given: all sides have length 35 inches.

AG + GD = AD

14 + GD = 35

GD = 21

Angles A and D are right angles and are congruent.

Angles AEG and DFG are marked congruent in the figure.

By AA Similarity, triangles EAG and FDG are similar.

The lengths of corresponding sides of similar triangles are proportional.

EG/AG = FG/GD

EG/14 = 24/21

EG/14 = 8/7

7(EG) = 14(8)

EG = 2 * 8

Step-by-step explanation:

Answer: The amount of money that he made on Monday is 0.86 times the amount of money that he made on Tuesday

Step-by-step explanation:

We know:

Monday = $1200

Tuesday = $1400

Now we want to know the ratio of Monday to Tuesday, that is a relation that directly relates both quantities, we can calculate it as:

Ratio from Monday to Tuesday = Monday/Tuesday = $1200/$1400 = 0.86

Then the amount of money that he made on Monday is 0.86 times the amount of money that he made on Tuesday

Answer: (1, √15) and (1, -√15)

Step-by-step explanation:

A circle centered at the point (a, b) of radius R can be written as:

(x - a)^2 + (y - b)^2 = R^2

In this case we have:

"A circle is centered at the origin (0,0) and has a radius of 4 units"

Then the equation for this circle is:

x^2 + y^2 = 4^2 = 16.

Now, we want to find the points where x = 1, then we can replace that value and solve the equation for y.

1^2 + y^2 = 16

1 + y^2 = 16

y^2 = 16 - 1 = 15

y = +-√15

Then the two points that have the x-coordinate equal to 1 are:

(1, √15) and (1, -√15)

The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

The equation of a circle usually takes the form;

where a and b are x- and y- coordinates of the center of the circle.

In this scenario, the center is at the origin (0,0).

In essence, the points on the circle which have an x-coordinate of 1 can be evaluated as follows;

The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

If the number of nickels is 7 less than three times the number of dimes, the answers should be 29 nickels and 12 dimes. Hope it helps!

Answer:

Step-by-step explanation:

given:

A piggy bank contains $2.65 in nickels and dimes.

If the number of nickels is 7 less than three times the number of dimes,

find:

how many of each kind of coin are there?

solution;

total = $2.65 = d + n

let d = dimes

    n = nickels

nickels = 3d - 7

plugin values into the formula:

2.65 = d + 3d - 7

2.65 + 7 = 4d

d = 9.65

d = $2.41

nickels = 3d - 7

            = 3(2.41) - 7
