Answer:

Step-by-step explanation:

Put the appropriate values of n in the formula and do the arithmetic.

  a(1) = 3·1 -7 = -4

  a(5) = 3·5 -7 = 8

The 1st and 5th terms are -4 and 8.

_____

The first few terms of the sequence are ...

  -4, -1, 2, 5, 8, 11, 14, ...

To find the sum of the 1st and 5th terms of the sequence defined by the function a(n) = 3n - 7, calculate each term using their respective n value and add the results together, resulting in a sum of 4.

When you are given the function a(n) = 3n - 7, which represents the value of the nth term in a sequence, the sum of the 1st and 5th terms of the sequence can be calculated by plugging in the values for n into the function for each term and adding the results.

For the 1st term (n = 1):

For the 5th term (n = 5):

The sum of the 1st and 5th terms is then:

-4 + 8 = 4

43% = 'Piano'

28% = 'Guitar'

15% = 'Harmonica'

12% = 'Drums'

2% = ...Other Instruments

- '2' Does seems as to be the smallest but it could be a trick.

- '43' Is the largest percentage out of the whole group.

- '100' Is what you get when you add all of the percentages together.

- And if you try to evaluate the percentages together in either way it'll end up to be '0.00004334' so that executes '250' and '150' from out of the question.

I'm not sure exactly what the actual answer could be but I'm assuming since it said "What is the smallest number of people required for the sample to meet the conditions for performing inference" Then my assumption is '2'.

250

Remember there are 2 conditions to perform a goodness of fit chi-test:

Simple random sample: The data must come from a random sample or a randomized experiment.

Expected counts: All expected counts are at least five. You must state the expected counts.

To explain expected counts a bit better, imagine I surveyed 100 people about their ice cream preferences. Before beginning it is believed that 50% like chocolate, 47% like vanilla, and 3% like strawberry.

That means our expected counts are:

100(.50) = 50

100(.47) = 47

100(.03) = 3

This is a problem, because 3 < 5 and so we can not perform a goodness of fit chi-test.

So how do you find the minimum sample size? Use this formula:

sample size (n) * smallest proportion (p) = 5

In the context of ice cream:

n*.03 = 5

n = 5 / .03

n = 167 (because you can't interview 2/3s of a person)

In the context of the problem:

n* .02 = 5

n = 5 / 0.02

n = 250

This means we need to sample at least 250 people to meet our expected count condition.

Answer:

S = 13 - x

T = (18 + x) / 2

Step-by-step explanation:

S = 18

T= 18

Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.

S = 18 - x

T= 18 + x

Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.

S = 18 - x - 5

T = 18 + x / 2

Simplify 18-5.

S = 13 - x

T = (18 + x) / 2

The order of the sides of the triangle is bc>ab>ac as per the rule that side opposite to the larger angle is larger

According to the rule that the side opposite to the larger angle is larger. The order of the sides of the triangle is bc>ab>ac .

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

Then, if these three values satisfy the relation:

939748.88 dollars is the answer

Answer:

$170,258.27

Step-by-step explanation:

Principal = $170,650

Interest = 5.5%

Term = 20 years

Monthly payment = $1,173.88

The interest on the first month is simply simple interest of 1 month on the principal.

I = prt = $170,650 * 0.055 * 1/12 = $782.15

Subtract the interest from the first months payment to find the amount of principal paid.

$1,173.88 - $782.15 = $391.73

Since the amount of principal paid on the first month is $391.73, the balance after paying the first month's payment is the original principal reduced by the amount of principal paid in the first month.

balance = $170,650 - $391.73 = $170,258.27

Answer:

t = 6: It takes 6 seconds for the object to hit the ground

Step-by-step explanation:

So, we need to find t when the height is 0. Since -5t² + 20t + 60 represents the height, that needs to equal 0.

Equation: -5t² + 20t + 60 = 0

Divide by -5: t² - 4t - 12 = 0

Find two numbers that add up to -4t and multiply to -12t²: -6t, 2t

Substitute: t² - 6t + 2t - 12 = 0

Factor: (t - 6)(t + 2) = 0

Answers: t = 6, t = -2

Since time can't be negative, t = 6.

To determine the time it takes for the object to hit the ground, the quadratic equation -5t^2 + 20t + 60 = 0 is solved, leading to the conclusion that it takes 6 seconds for the object to reach the ground.

The question asks, "How many seconds does it take for the object to hit the ground?" given the function f(t) = -5t2 + 20t + 60. To find when the object hits the ground, we need to determine when the height f(t) is equal to 0. This involves solving a quadratic equation.

Steps to Solve:

Set the equation equal to zero: -5t2 + 20t + 60 = 0.

Divide the entire equation by -5 to simplify: t2 - 4t - 12 = 0.

Use the quadratic formula: t = (-B ± √(B2 - 4AC)) / 2A, where A = 1, B = -4, and C = -12.

Calculate the discriminant: √((-4)2 - 4(1)(-12)) = √(16 + 48) = √64 = 8.

Substitute values into the formula: t = (4 ± 8) / 2, yielding t = 6 seconds or t = -2 seconds.

Dismiss the negative value, as time cannot be negative, leaving t = 6 seconds as the solution.

Therefore, it takes the object 6 seconds to hit the ground after it is launched.

Collect in terms of x:

x (3 - a) + 4 = 9 - 7 x + b x

Collect in terms of x:

x (3 - a) + 4 = x (b - 7) + 9

3m. The wall of the building is 3m far from the base of the ladder.

The key to solve this problem is use trigonometric ratios.

The cosine of the angle is the adjacent leg divided by the hypotenuse.

From the image attached we can modeling the problem as a right triangle, where we can see that the adjacent leg is the unknown, hypotenuse is 6m (long of the ladder), and the ladder make an angle of 60°  leans againts the building's wall, and x is the long of the adjacent leg. To calculate how far is the base of the ladder from the wall:

Cos 60° = adjacent leg/hypotenuse

adjacent leg = cos 60° x hypotenuse

x = cos 60° (6m) = (0.5)(6m) = 3m

Step-by-step explanation:

we know that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

[tex]C=2\pi r[/tex]

we have

[tex]r=30/2=15\ in[/tex] -----> the radius is half the diameter

substitute

[tex]C=2\pi(15)[/tex]

[tex]C=30\pi\ in[/tex]

assume

[tex]\pi =3.14[/tex]

[tex]C=30(3.14)=94.2\ in[/tex]

Remember that    

The circumference of the wheels represent one revolution

Convert 59 miles per hour to inches per minute

[tex]59\ mi/h=59*63,360/60=62,304\ in/min[/tex]

using proportion find the number of revolutions  

[tex]\frac{1}{94.2}\frac{rev}{in}=\frac{x}{62,304}\frac{rev}{in}\\ \\x=62,304/94.2\\ \\x=661.4\ rev[/tex]

therefore

substitute

[tex]62,304\ in/min=661.4\ rev/min=661.4\ rpm[/tex]

the angular velocity of the truck's wheels is approximately 661.03 rpm

We need to first convert 59 mph into in/h. For this we can use the conversion factor:

[tex]1\ mile = 63360\ in[/tex]

Thus, 59 mph in ft/h will be:

[tex]59 \times 63360 = 3738240\ in/h[/tex]

Now we need to convert this into in/min for which we can use the conversion factor:

[tex]1\ hour = 60\ minute[/tex]

So, on converting we get:

[tex]\frac{3738240}{60} = 62304\ in/min[/tex]

Radius of tire will be half of its diameter. Thus radius = 15 in

Circumference of tire can be calculated by using the formula:

[tex]circumference = 2 \pi r[/tex]

Putting in values we get:

[tex]Circumference = 2 \times \pi \times 15 \approx 94.25\ in[/tex]

To determine the number of rotations per minute we need to divide speed of tire by the circumference of tire as follows:

[tex]rpm = \frac{speed}{circumference}\\\\\\rpm = \frac{62304}{94.25} \approx 661.03\ rpm[/tex]

Therefore, the angular velocity of the truck's wheels is approximately 661.03 rpm
