Step-by-step explanation:

We can estimate* that the total price including tax of the game will be less than ...

  $43.31 +10% of 43.31 = $43.31 +4.33 = $47.61

Todd easily has enough to pay for the game, including tax.

_____

You can work this more exactly a couple of ways.

  1. Price + tax = 1.085×$43.31 = $46.99 . . . less than Todd's budget

  2. Most Todd can afford: $55.50/1.085 = $51.15 . . . more than the game price

_____

* For estimating purposes, we like to use numbers that are easy to compute with. 10% is one such number, as it only requires moving the decimal point.

Answer:

For this case we know that the confidence interval is given by (1.2 , 1.8) and the point of estimate for [tex]\mu[/tex] would be:

[tex]\bar X = \frac{1.2+1.8}{2}= 1.5[/tex]

And the margin of error is given by:

[tex] ME = \frac{1.8-1.2}{2}= 0.3[/tex]

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

[tex]\bar X[/tex] represent the sample mean for the sample  

[tex]\mu[/tex] population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

Solution to the problem

The confidence interval for the mean is given by the following formula:

[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex]   (1)

For this case we know that the confidence interval is given by (1.2 , 1.8) and the point of estimate for [tex]\mu[/tex] would be:

[tex]\bar X = \frac{1.2+1.8}{2}= 1.5[/tex]

And the margin of error is given by:

Step-by-step explanation:

The first equation tells you that y cannot be negative. (Both terms are positive.) So, the only viable answer choice is A.

The frequency of the note a perfect fifth below C4, which is F3, is calculated by multiplying the frequency of C4 (261.63 Hz) by 2/3, resulting in 174.42 Hz.

The frequency of the musical note C4 is about 261.63 Hz. A perfect fifth below a note is 7 half-steps below on the chromatic scale, which corresponds to a frequency ratio of approximately 2/3. Therefore, to find the frequency of the note that is a perfect fifth below C4, we multiply the frequency of C4 by 2/3.

Calculating this, 261.63 Hz × (2/3) = 174.42 Hz which is the note F3. Hence, the frequency of the note a perfect fifth below C4 is 174.42 Hz.

Answer: The displacement is -4 ft.

Step-by-step explanation:

The velocity is:

v(t) = 2t - 5ft/s

If we want to find the displacement between t = 0s and t = 4s, we need to find the difference between the position at t = 0s and at t= 4s

The equation for the position is obtained by integrating over time:

P(t) = (2t^2)/2 - 5*t + c

where c is the initial position, then we have:

P(t) = t^2 - 5t

P(4) - P(0) = 4*4 - 5*4 - 0 = 16 - 20 = -4

The total displacement is -4 feet

Answer:

Displacement, d = - 4ft

Step-by-step explanation:

Given,

The velocity function for a particle v(t) = 2t - 5 ft/sec.

To obtain the displacement for the particle from t = 0 to t = 4 sec

We integrate v(t) with respect to t

: Displacement, d = ∫₀⁴ ( 2t - 5) dt

= t² - 5t |₀⁴ = (4² - 5(4)) - 0² - 5(0)

=16 - 20 = - 4ft

This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.

Step-by-step explanation:

A survey is being conducted to determine how a city's residents feel about building a new youth center.

They are considering to survey 50 random children at a local elementary school.

This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.

Moreover, it is likely that the students of elementary school might not even have any interest in youth center so results would be biased.

Therefore, it is suggested to include a variety of samples that is surveying different age groups that covers all of the community.

Answer:

1. The survey is only considering elementary school students, but not children in middle school or high school.

2. The survey is also not considering any adult at all. Most likely they represent the majority of the local residents.

3. Finally, it's important to understand in advance what would be the main differences with the current youth center and include those specific questions in the survey. It's important to determine if the new youth center will fill the gap.

The mean and median will change.

Step-by-step explanation:

Mean takes the sum of all the numbers and divide by the amount of numbers there are. This would add 1 to the denominator, which would decrease the total mean score, as the numerator does not change.

The Median will also change. The median is found by finding the middle number of the set. Adding 0 to the set would result in a different number being chose for the median.

Answer:

The speed of light through the medium is 2.1 * 10^8 m/s

Step-by-step explanation:

In this question, we are asked to calculate the speed of light beam as it travels through a medium given the refractive index of the medium.

Mathematically;

n = c/v

where n is the refractive index, v is the speed of light through the medium and c is the speed of light in a vacuum.

From the question, we can identify that the refractive index is 1.46 and the speed of light through vacuum is 3 * 10^8 m/s

Rearranging the equation; we have;

v = c/n

v = (3 * 10^8)/1.46

v = 2.1 * 10^8 m/s

Answer:

Goldbach’s Conjecture precipitated from letters in 1742 between German mathematician Christian Goldbach and legendary Swiss mathematician Leonhard Euler, considered one of the greatest in math history. As Euler put it, “I regard [it] as a completely certain theorem, although I cannot prove it.”

Euler may have sensed what makes this problem counterintuitively hard to solve. When you look at larger numbers, they have more ways of being written as sums of primes, not less. Like how 3+5 is the only way to break 8 into two primes, but 42 can broken into 5+37, 11+31, 13+29, and 19+23. So it feels like Goldbach’s Conjecture is an understatement for very large numbers.

Still, a proof of the conjecture for all numbers eludes mathematicians to this day. It stands as one of the oldest open questions in all of math.

Answer:

7.065 m ^ 2

8.935 m ^ 2

Step-by-step explanation:

The first thing is to calculate the surface of each one, that is, the area

For the room that is square, each side measures 4m, therefore:

As = 4 * 4 = 16 m ^ 2

The area of the carpet is that of a circle, that its area is the number pi times the radius squared, we know that the radius is half the diameter, therefore r = 3/2 = 1.5 m

replacing in the area formula

Ac = pi * r ^ 2 = 3.14 * 1.5 ^ 2

Ac = 7.065 m ^ 2

In other words, the area covered by the carpet is 7,065 m ^ 2 and the area not covered would be the subtraction between the area of the room minus the area of the carpet, that is:

16 m ^ 2 - 7.065 m ^ 2 = 8.935 m ^ 2

8.935 m ^ 2 would be the area that the carpet does not subside.

a) How much does the employer pay annually

b) How much does she pay annually

c) How much is deducted each week as her weekly cost

a)

Given that:

The annual premium = $6180

Employers percent = 75% = 0.75

The money the employer pays annually = Annual premium × Employers percent = $6180 × 0.75 = $4635

Answer:

The correct answer is 4 window frames.

Step-by-step explanation:

Sue bought 54 feet of lumber for building window frame.

Each window frame requires 13 1/2 feet = [tex]\frac{27}{2}[/tex] feet of lumber.

Therefore the number of window frames Sue can make with 54 feet of lumbers she bought is given by dividing the total amount of lumber she has by the lumber it takes to make a single window frame.

= [tex]\frac{54}{27}[/tex] × 2 = 2 × 2 = 4

Thus Sue can make 4 window pane from 54 feet of lumber, each of 13 and a half feet.

Sue can make 4 window frames with the 54 feet of lumber she purchased, as each frame requires 13.5 feet.

Sue bought 54 feet of lumber to build window frames, with each window frame requiring 13.5 feet of lumber. To determine how many window frames Sue can make, we divide the total amount of lumber by the amount required for one frame.

Here's the calculation:

Start with the total amount of lumber: 54 feet.

Divide this by the amount required for one window frame: 13.5 feet.

Perform the division: 54 / 13.5 = 4.

Sue can make 4 window frames with the lumber she has purchased.
