The common difference is 1.5

Use the explicit formula to find a1.

a1 = 1.2

What is the explicit formula for the arithmetic sequence?

= 1.2 + (n - 1)1.5

Step-by-step explanation:

Answer 2

Final answer:

The common difference of the arithmetic sequence is 1.5, and the first term is 1.2. The explicit formula for the arithmetic sequence is A: an = 1.2 + (n - 1)1.5.

Explanation:

To find the common difference of an arithmetic sequence, we can use the information that the seventh term (a7) is 10.2 and the twelfth term (a12) is 17.7. The formula for the nth term of an arithmetic sequence is an = a1 + (n - 1)d, where a1 is the first term and d is the common difference. By creating a system of equations using the given terms, we can solve for d.

For the seventh term: 10.2 = a1 + 6d
For the twelfth term: 17.7 = a1 + 11d
Subtracting the first equation from the second gives: 17.7 - 10.2 = 5d, which simplifies to 7.5 = 5d or d = 1.5.

We can then plug the value of d back into one of the equations to find a1:
10.2 = a1 + 6(1.5)
10.2 = a1 + 9
a1 = 1.2

Therefore, the explicit formula for this arithmetic sequence is A: an = 1.2 + (n - 1)1.5.

The maximum value of y in the equation y = -x2 + 6x – 8 is y=

Answers

Answer:

  1

Step-by-step explanation:

A graph shows you very quickly that the maximum value of y is 1.

__

There are several ways to get there algebraically. The axis of symmetry is given for ax^2 +bx by x=-b/(2a). Here, that value is x=(-6)/(2(-1)) = 3. The maximum y-value will correspond to this x-value:

  y = -3² +6·3 -8 = -9 +18 -8 = 1

The maximum value of y is 1.

__

The axis of symmetry can also be found by factoring:

  y = -(x -4)(x -2)

It is halfway between the values of x that make these factors zero, so is ...

  x=(4+2)/2 = 3

For that value of x, we find y to be ...

  y = -(3 -4)(3 -2) = 1

__

We can also rearrange the equation to vertex form:

  y = -(x^2 -6x) -8

  = -(x^2 -6x +9) -8 -(-9)

  = -(x -3)^2 +1

The vertex is (3, 1), so the maximum value of y is 1.

It took Jerry 3 4/5 hours to get to his grandmother's house. He walked for 2/5 hour to the train station, rode on a train for 1 4/5 hours, and then took a bus. How much time did Jerry spend riding on the bus?

Answers

Jerry spent 4/5 hour riding on the bus.

First, let's find the total time Jerry spent walking and riding the train:

Walking time = 2/5 hour

Train ride time = 1 4/5 hours

To find the total time spent, add these two:

2/5 + 1 4/5 = (2/5) + (1 + 4/5) = (2/5) + (1 + 4/5) = (2/5) + (5/5 + 4/5) = (2/5) + (9/5) = (2 + 9)/5 = 11/5 hours

Now, since Jerry spent a total of 11/5 hours walking and riding the train, to find out how much time he spent on the bus, we subtract this from the total time it took him to get to his grandmother's house:

Total time = 3 4/5 hours

Bus ride time = Total time - (Walking time + Train ride time)

              = 3 4/5 - 11/5

              = (15/5) - (11/5)

              = 4/5 hours

Lucy and Katy are registering for a sports league for next year. There are 2 sports (volleyball and basketball) and 3 seasons (fall, winter, and spring) to choose from. They each created a display to represent the sample space of randomly picking a sport and a season. Whose display correctly represents the sample space?

Answers

Answer:

The sample space is: AV, WV, SV, AB, WB, and SB

Step-by-step explanation:

The sample space has all the possibilities in which Lucy and Katy can register for a sports league. Now, they have 2 sports and 3 seasons.

So, let's call V that they register in volleyball and B that they register in basketball. Additionally, let's call A that they register for fall, W that they register for winter, S that they register for spring.

It means that the sample space is:

AV, WV, SV, AB, WB, and SB

where, for example, AV is the possibility to be registered in fall and in volleyball.

Therefore, the display that correctly represents the sample space is the one that has all these possibilities.

You drop a ball from a stair case that is 36 ft high. By the time you get down the stairs to measure the height of the bounce, the ball has bounced four times and has a height of 2.25 ft after its fourth bounce. How high did the ball bounce after it first hit the floor?

Answers

Answer:

18 feet

Step-by-step explanation:

After each bounce, the ball reaches only a percentage of the maximum height it reached before.

The first height is 36 feet, after the first bounce, it will be 36*r, where r is the ratio of the height the ball can still reach by the previous maximum height.

In the second bounce, the height is 36*r^2

In the third bounce, the height is 36*r^3

In the fourth bounce, the height is 36*r^4, and this value is 2.25 ft, so:

36*r^4 = 2.25

r^4 = 2.25/36

r^4 =  0.0625

r = 0.5

So, after the first bounce, the height is:

36*r = 36*0.5 = 18 feet

The height should be 18 feet.

Given that,

You drop a ball from a stair case that is 36 ft high. By the time you get down the stairs to measure the height of the bounce, the ball has bounced four times and has a height of 2.25 ft after its fourth bounce.

Based on the above information, the calculation is as follows:

The first height is 36 feet.

Now after the first bounce, it will be 36r

Here r is the ratio of the height

In the second bounce, the height is [tex]36\times r^2[/tex]

In the third bounce, the height is [tex]36\times r^3[/tex]

In the fourth bounce, the height is [tex]36\times r^4[/tex], and this value is 2.25 ft, so:

Now

[tex]36\times r^4 = 2.25\\\\r^4 = 2.25\div 36\\\\r^4 = 0.0625[/tex]

r = 0.5

Now  

So, after the first bounce, the height is:

= 36r

= 36(0.5)

= 18 feet

Therefore we can conclude that The height should be 18 feet.

A recent survey reveals that 40% of young people between 15 and 25 years of age will buy an iPod this year. Of those who buy iPods 35% enjoy listening to country music. If N is the number of young people between 15 and 25. How many people between 15 and 25 this year will enjoy listening to country music on their iPods?
a) 14N.
b) 1.4N.
c) 0.14N.
d) 1.14N.

Answers

Answer:

The option C) 0.14N is correct ∴  35 % are enjoy  listening to Country music is 0.14N

Step-by-step explanation:

Given that "A recent survey reveals that 40% of young people between 15 and 25 years of age will buy an iPod this year. If N is the number of young people between 15 and 25"

To find how many people between 15 and 25 this year will enjoy listening to country music on their iPods:

From the given we can write

Total people between 15 and 25 age = N

Number of people who buys iPods is 40% of  N is

[tex] = \frac{40}{100}\times N[/tex]

= 0.4N

∴ Number of people who buys iPods is 40% of  N is 0.4N

From the given we have that 35 % are enjoy  listening to Country music means  

[tex]= \frac{35}{100}\times 0.4N[/tex]

[tex]=0.35\times 0.4N[/tex]

= 0.14N

∴  35 % are enjoy  listening to Country music is 0.14N Hence option C) 0.14N is correct.

Final answer:

Calculating 35% of 40% of the young people between 15 and 25 years who will buy an iPod, the number who will enjoy listening to country music on their iPods is 0.14N, making choice (c) the correct answer.

Explanation:

To determine the number of young people between 15 and 25 years old who will enjoy listening to country music on their iPods this year, we can first calculate the number of young people who will buy an iPod. Since 40% of the group is expected to buy an iPod, this is 0.40N. Next, out of these iPod owners, 35% enjoy listening to country music. Therefore, we can find the number of iPod owners who enjoy country music by taking 35% of the 40%, which is 0.35  times 0.40N. This calculation results in 0.14N young people enjoying country music on their iPods.

This leads us to the answer choice (c) 0.14N.

can 5ft 9ft 14ft make a triangle?

Answers

Answer:

Any dimensions can make a triangle, however

this does not make a right angled triangle.

Step-by-step explanation:

Determine the length of the hypotenuse of a right angle triangle with side lengths 5ft and 9ft by using the formula:

[tex]a^2+b^2=c^2\\[/tex]

[tex]\sqrt{a^2+b^2} = c[/tex]

[tex]c=10.29[/tex]

This is not equal to 14ft.

Answer: No, those measurements cannot make a triangle

Why not? Because of the fact that the first two sides (5 and 9) add to 5+9 = 14, which is exactly as long as the third side. I recommend you using a ruler to measure out 5 inches, 9 inches and 14 inches. Mark all three as separate segments on a piece of paper. Then cut out those segments to form strips of paper with the given lengths. Then try to form a triangle. You'll find that it is impossible since the smaller segments combine perfectly to get the longest segment. Instead of a triangle, you'll only have a line segment forming.

As a rule, when you add any two sides of a triangle, they must add to something larger than the third side. The rule more formally is

For any triangle with sides a,b,c, the following three inequalities must hold true

a+b > ca+c > bb+c > a

A local newspaper said that the city of Luttrell is expected to grow by 10% each year. The population in 2012 is 130,457 people. Let t represent the number of years after 2012. Which equation could be used to determine the total expected population, P, of Luttrell in t years?

Answers

Final answer:

The formula to calculate the expected population of Luttrell in t years, with a 10% annual growth rate, is P = 130,457 × (1 + 0.10)^t.

Explanation:

To determine the total expected population, P, of Luttrell in t years, given an annual growth rate of 10%, you would use the formula for exponential growth: P = P0 × (1 + r)t, where P0 is the initial population, r is the growth rate (expressed as a decimal), and t is the number of years after the initial time. In this case, since the population in 2012 (which is our initial time) is 130,457, and the growth rate is 10% or 0.10, the equation becomes P = 130,457 × (1 + 0.10)t. This equation will calculate the expected population after t years.

Final answer:

The equation to determine the total expected population of Luttrell in t years is P = [tex]130,457 × (1 + 0.10)^t,[/tex] where P is the population and t represents the number of years after 2012.

Explanation:

To determine the total expected population, P, of Luttrell in t years, given that it is expected to grow by 10% each year, you can use an exponential growth formula. The formula incorporating this percentage growth rate and starting population in 2012 is:

P = 130,457 × (1 + 0.10)^t

Here, 130,457 is the initial population in the year 2012, 1 + 0.10 represents the growth factor (where 0.10 is the 10% growth converted to a decimal), and t is the number of years after 2012.

For example, to find the population after 1 year (t = 1), you would calculate:

P =[tex]130,457 × (1 + 0.10)^1 = 130,457 × 1.10 = 143,502.7,[/tex] which you would round to the nearest whole person.

On the school playground, the slide is 7 feet due west of the tire swing and 7 feet due south of the monkey bars. What is the distance between the tire swing and the monkey bars?

Answers

Answer:

Step-by-step explanation:

According to the question, a slide is 7 feet due west of a tire swing and 7 feet due right of the monkey bars and we were asked the calculated the distance between them.

If you look at it carefully, since the slide is due west of the tire swing and 7 feet due south of the monkey bars, you'll notice a shaped form, the shape formed is an inverted right-angled triangle.

Right-angled Triangles can be solved using pythagoras' theorem which says [tex]a^{2} + b^{2} = c^{2}[/tex].

a= 7, b=7, c=??

[tex]c^{2} = 7^{2} + 7^{2}[/tex]

[tex]c =\sqrt{98}[/tex]

c = 9.9 feet

Final answer:

The distance between the tire swing and the monkey bars is found using the Pythagorean theorem, which gives approximately 9.90 feet.

Explanation:

To find the distance between the tire swing and the monkey bars, we can model the situation using a right triangle. The slide being 7 feet due west of the tire swing and 7 feet due south of the monkey bars forms a right-angled triangle with the slide as the vertex where the right angle is, the tire swing and monkey bars forming the other two vertices.

Using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the legs (a and b), we can find the distance (hypotenuse) between the tire swing and the monkey bars.

In other words, we have:

a² + b² = c²

Given:

a = 7 feet (distance from slide to tire swing)

b = 7 feet (distance from slide to monkey bars)

We can calculate:

c² = 72 + 72 = 49 + 49 = 98

The distance (c) is the square root of 98, which is approximately 9.90 feet.

Therefore, the distance between the tire swing and the monkey bars is approximately 9.90 feet.

Answers

Final answer:

To calculate Payne's annual contribution, multiply the annual premium by 20% and subtract that amount from the annual premium.

Explanation:

To calculate Payne's annual contribution, we need to determine 20% of the total cost of the health insurance premium and then subtract that amount from the annual premium.

Step 1: Find 20% of $6,486. Multiply $6,486 by 0.2 to get $1,297.20.

Step 2: Subtract the 20% contribution from the annual premium. $6,486 - $1,297.20 = $5,188.80.

Payne's annual contribution is $5,188.80.

Both genetic and nongenetic factors are thought to be responsible for club foot. C. A. Gurnett et al. (2008. American Journal of Human Genetics 83:616622) identified a family in which club foot was inherited as an autosomal dominant trait with reduced penetrance. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. What is the penetrance of PITXI mutation in this family?

What is the diameter of the circle? An experiment was performed to compare the wear of two different laminated materials. Twelve pieces of material 1 were tested by exposing each piece to a machine measuring wear. Ten pieces of material 2 were similarly tested. In each case, the depth of wear was observed. The samples of material 1 gave an average (coded) wear of 85 units with a sample standard deviation of 4, while the samples of material 2 gave an average of 81 with a sample standard deviation of 5. Can we conclude at the 0.05 level of significance that the abrasive wear of material 1 exceeds that of material 2 by more than two units?
