Step-by-step explanation:

To find the value of a6, we need to first determine the value of a2, a3, a4, and a5 using the given recurrence relation:

a1 = 6

a2 = 5a1 = 5(6) = 30

a3 = 5a2 = 5(30) = 150

a4 = 5a3 = 5(150) = 750

a5 = 5a4 = 5(750) = 3750

Now, we can find a6 using the recurrence relation:

a6 = 5a5 = 5(3750) = 18750

Therefore, the value of a6 is 18750.

Answer:

132°

Step-by-step explanation:

y°=7x+20° (vertically opposite angles)

3x°+7x°+20°=180° (interior angles, since M is parallel to N)

10x+20°=180°

10x=180°-20°

10x=160°

x=16°

y°=7(16°)+20°

y°=112°+20°

y°=132°

Answer:

Slope of a horizontal line. When two points have the same y-value, it means they lie on a horizontal line. The slope of such a line is 0, and you will also find this by using the slope formula.

We can be 99% confident that the true mean healing rate of newts falls within the interval of 22.919 to 30.415 micrometers per hour.

Sample Mean: = (29 + 27 + 34 + 40 + 22 + 28 + 14 + 35 + 26 + 35 + 12 + 30 + 23 + 18 + 11 + 22 + 23 + 33) / 18

= 480 / 18

≈ 26.667

Sample Standard Deviation (s):

= ✓((Σ(29 - 26.667)² + (27 - 26.667)² + ... + (33 - 26.667)²) / (18 - 1))

≈ ✓(319.778 / 17)

≈ ✓(18.81)

≈ 4.336

Confidence level = 99%

Sample Size (n) = 18

Sample Mean = 26.667

Sample Standard Deviation (s) = 4.336

Degrees of Freedom (df) = n - 1 = 18 - 1 = 17

Using a t-table or statistical software, we find that the critical value for a 99% confidence level with 17 degrees of freedom is approximately 2.898.

Margin of Error (E) = 2.898 * (4.336 / ✓18))

≈ 3.748

Confidence Interval = (26.667 - 3.748, 26.667 + 3.748)

= (22.919, 30.415)

We can be 99% confident that the true mean healing rate of newts falls within the interval of 22.919 to 30.415 micrometers per hour. This means that if we were to repeat the study multiple times and construct confidence intervals, approximately 99% of those intervals would contain the true mean healing rate of the population.

Part G: What is the frequency of type A blood in this population? Enter your answer to two decimal places.

Part H: What is the frequency of type B blood in this population? Enter your answer to four decimal places.

Part I: What is the frequency of type AB blood in this population? Enter your answer to two decimal places.

Part J: What is the frequency of type O blood in this population? Enter your answer to four decimal places.

Answer: Part A: f(IAIA) = 0.09

              Part B: f(IBIB) = 0.0225

              Part C: f(IAIB) = 0.05

              Part D: f(IAi) = 0.16

              Part E: f(IBi) = 0.082

              Part F: f(ii) = 0.3025

              Part G: f(type A) = 0.25

              Part H: f(type B) = 0.1050

              Part I: f(type AB) = 0.05

              Part J: f(type O) = 0.3025

Step-by-step explanation: A population in Hardy-Weinberg equilibrium is a population with a constant value in the population's allele frequency.

In the population of Taiwan, frequencies are:

A: Frequency for genotype IAIA: Frequency of allele A is 0.3, then for genotype IAIA:

f(IAIA) = 0.3²

f(IAIA) = 0.09

B: Frequency of allele B is 0.15. Then, for genotype IBIB:

f(IBIB) = 0.15²

f(IBIB) = 0.0225

C: Frequency for genotype IAIB:

f(IAIB) = 0.3*0.15

f(IAIB) = 0.05

D: Frequency for genotype IAi:

f(IAi) = 0.3*0.55

f(IAi) = 0.16

E: frequency for genotype IBi:

f(IBi) = 0.15*0.55

f(IBi) = 0.082

F: frequency for allele i is 0.55. Then, for genotype ii:

f(ii) = 0.55²

f(ii) = 0.3025

Individuals with type A blood can be IAIA or IAi. Using probability's "OR" rule:

f(type A) = 0.09 + 0.165

f(type A) = 0.25

The same happens to individual with type B blood:

f(type B) = 0.0225 + 0.0825

f(type B) = 0.105

Since blood type is a codominance, i.e., allele A and allele B are expressed, frequency of type AB is equal to frequency of genotype AB:

f(type AB) = 0.3*0.15

f(type AB) = 0.05

Frequency for type O is:

f(type O) = 0.55²

f(type O) = 0.3025

Answer:

  decreasing 0.5 m/s

Step-by-step explanation:

You want the rate at which the height of a shadow on a wall is decreasing as a 2 m tall man walks at 1.3 m/s toward the wall. The shadow is cast by a light 12 m from the wall, and the man is 4 m from the wall at the time of interest.

In the attached diagram, triangles ABC and LMA are similar. This lets us write the proportion ...

  y/x = 2/(12 -x)

  y = 2x/(12 -x) . . . . . . multiply by x to get expression for y

Taking the derivative with respect to time gives ...

  y' = (2/(12 -x) +2x/(12-x)²)x'

At x = 4, this is ...

  y' = (2/8 +8/8²)x' = (3/8)x'

When x' = -1.3 m/s, the rate of change of the shadow height is ...

  y' = (3/8)(-1.3 m/s) = -0.4875 m/s

The length of the shadow is decreasing at about 0.5 m/s.

In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.

In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.

To find the value of x in the given proportions, let's solve them one by one:

(5x + 1) : 3 = (2x + 2) : 7

To solve this proportion, we can cross-multiply:

7(5x + 1) = 3(2x + 2)

35x + 7 = 6x + 6

Subtracting 6x from both sides and subtracting 7 from both sides:

35x - 6x = 6 - 7

29x = -1

Dividing both sides by 29:

x = -1/29

Therefore, the value of x in the first proportion is -1/29.

(6x) : (4x) = 7

To solve this proportion, we can simplify the left side:

6x / 4x = 7

Dividing both sides by 2x:

3/2 = 7

This equation is not true, as 3/2 is not equal to 7.

Therefore, there is no value of x that satisfies the second proportion.

In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

The equation in terms of x that represents the given relationship is 114 = (1 + 3x) * (Width)

Let's break down the information given:

Height of the rectangular box = 7 ft

Length of the rectangular box = 1 ft longer than thrice the width (x)

Volume of the rectangular box = 798 ft³

To write an equation that represents the given relationship, we need to relate the length, width, and height to the volume.

The volume of a rectangular box is given by the formula: Volume = Length * Width * Height.

Given that the height is 7 ft, we can substitute this value into the equation.

Volume = (Length) * (Width) * (7)

Now, let's focus on the length. It is described as 1 ft longer than thrice the width.

Length = 1 + (3x)

Substituting this value into the equation, we have:

Volume = (1 + (3x)) * (Width) * (7)

Since the volume is given as 798 ft³, we can set up the equation as follows:

798 = (1 + (3x)) * (Width) * 7

Simplifying further, we get:

798 = 7 * (1 + 3x) * (Width)

Dividing both sides of the equation by 7, we have:

114 = (1 + 3x) * (Width)

Therefore, the equation in terms of x that represents the given relationship is:

114 = (1 + 3x) * (Width)
