What are the eight-digit grid coordinates for benchmark 86 (circled in red)?

Answers

Answer 1
Final answer:

Without a map or structured dataset, it is not possible to provide the eight-digit grid coordinates for benchmark 86 as requested.

Explanation:

The student asked for the eight-digit grid coordinates for benchmark 86, which is circled in red. To determine the eight-digit grid coordinates, we need a map with grid lines or specific information that provides the exact location of benchmark 86. Unfortunately, the data provided does not contain adequate information to pinpoint the exact eight-digit grid coordinates for this benchmark. Grid coordinates are typically derived from a more structured dataset or map rather than the types of numbers presented in the question. Those appear to be an arbitrary sequence of numbers and are not formatted as grid coordinates, which usually consist of an easting and a northing.

Sociologists want to test whether the number of homeless people in a particular urban area is increasing. In 2010, the average number of homeless people per day who sought shelter was 42.3 (σ = 6.2). Data from the current year reveal that the mean number of people seeking shelter per day is 45.3. Compute the test statistic using an alpha = .01 and n = 1000.

Answers

Answer:

The test statistic value is 15.3.

Step-by-step explanation:

The hypothesis for this test is:

H₀: The average number of homeless people is not increasing, i.e. μ = 42.3.

Hₐ: The average number of homeless people is increasing, i.e. μ > 42.3.

Given:

[tex]\bar x=45.3\\\sigma=6.2\\n=1000[/tex]

As the population standard deviation is provided use a single mean z-test for the hypothesis testing.

The test statistic is:

[tex]z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{45.3-42.3}{6.2/\sqrt{1000}}=15.3[/tex]

Thus, the test statistic value is 15.3.

Using the z-distribution, it is found that the test statistic is of z = 15.3.

At the null hypothesis, it is tested if the mean number has not increased, that is, it still is of 42.3, hence:

[tex]H_0: \mu = 42.3[/tex]

At the alternative hypothesis, it is tested if it has increased, that is, the mean is greater than 42.3, hence:

[tex]H_1: \mu > 42.3[/tex]

We have the standard deviation for the population, hence, the z-distribution is used.

The test statistic is:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. [tex]\sigma[/tex] is the standard deviation of the sample. n is the sample size.

For this problem, the values of the parameters are:

[tex]\overline{x} = 45.3, \mu = 42.3, \sigma = 6.2, n = 1000[/tex]

Hence:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{45.3 - 42.3}{\frac{6.2}{\sqrt{1000}}}[/tex]

[tex]z = 15.3[/tex]

The test statistic is of z = 15.3.

A trampolinist steps off from 15 feet above ground to a trampoline 13 feet below. The function h (t) = -16 t 2 + 15, where t represents the time in seconds, gives the height h, in feet, of the trampolinist above the ground as he falls. When will the trampolinist land on the trampoline?

Answers

Answer:

Trampolinist will land on the trampoline after 0.9 seconds.

Step-by-step explanation:

The function h(t) = -16t² + 15 represents the relation between height 'h' above the ground and the time 't' of the trampolinist.

We have to find the time when trampolinist lands on the ground.

That means we have to find the value of 't' when h(t) = 15 - 13 = 2

[Since trampoline is 2 feet above the ground]

When we plug in the value h(t) = 2

2 = -16t² + 15

2 + 16t² = -16t² + 16t² + 15

16t² + 2 = 15

16t² + 2 - 2 = 15 - 2

16t² = 13

[tex]\frac{16t^{2}}{16}=\frac{13}{16}[/tex]

[tex]t^{2}=\frac{13}{16}[/tex]

t = [tex]\sqrt{\frac{13}{16}}[/tex]

t ≈ 0.9 seconds

Therefore, trampolinist will land on the trampoline at 0.9 seconds.

Answers

Option C: [tex](4 j+3)^{2}[/tex] is the correct answer.

Explanation:

The given expression is [tex]16 j^{2}+24 j+9[/tex]

We need to factor the expression.

Let us rewrite the expression as

[tex](4j)^{2}+24 j+(3)^2[/tex]

Also, we can rewrite the term [tex]24j[/tex] as [tex]2(4)(3)j[/tex]

Thus, we have,

[tex](4j)^{2}+2(4j)(3)+(3)^2[/tex]

Hence, the equation is of the form,

[tex](a+b)^{2}=a^{2}+2 a b+b^{2}[/tex]

where [tex]a=4 j[/tex] and [tex]b=3[/tex]

Hence, the factor of the expression can be written as [tex](4 j+3)^{2}[/tex]

Thus, the factored expression is [tex](4 j+3)^{2}[/tex]

Therefore, Option C is the correct answer.

Final answer:

The factored form of the expression 16j^2 + 24j + 9 is (4j + 3)².

Explanation:

To factor the expression 16j2 + 24j + 9, we look for two binomials ((aj + b)(cj + d)) that when multiplied together, give us the original quadratic expression. The factors of 16j2 are 4j imes 4j, and the factors of 9 are 3 imes 3. Our binomial factors will have the format (4j + 3).

Expanding the binomial (4j + 3)², we have:

(4j + 3) imes (4j + 3)

= 16j2 + 12j + 12j + 9

= 16j2 + 24j + 9

This matches the original expression exactly, so the factored form of the expression is (4j + 3)².

Dustin bought 9 pencils. Some of the pencils were green and cost $0.90 each. The remainder of the pencils were purple and cost $0.65 each. If Dustin paid $7.10 for all of the pencils, how many green pencils did he buy?

Answers

Answer: he bought 5 green pencils

Step-by-step explanation:

Let x represent the number of green pencils that Dustin bought.

Dustin bought 9 pencils. The remainder of the pencils were purple. This means that the number of purple pencils that he bought is 9 - x

Some of the pencils were green and cost $0.90 each. The remainder of the pencils were purple and cost $0.65 each. If Dustin paid $7.10 for all of the pencils, it means that

0.9x + 0.65(9 - x) = 7.1

0.9x + 5.85 - 0.65x = 7.1

0.9x - 0.65x = 7.1 - 5.85

0.25x = 1.25

x = 1.25/0.25

x = 5

Find the volume of a right circular cone that has a height of 8.8 cm and a base with a diameter of 18.6 cm. Round your answer to the nearest tenth of a cubic centimeter.

Answers

Final answer:

The volume of the cone is approximately 860.6 cm³.

Explanation:

To find the volume of a right circular cone, we can use the formula V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone. In this case, the diameter of the base is 18.6 cm, so the radius is half of that, which is 9.3 cm. The height of the cone is 8.8 cm. Plugging these values into the formula, we get V = (1/3)π(9.3 cm)²(8.8 cm). Calculating this, we find that the volume of the cone is approximately 860.6 cm³.

Chloé had 100 math problems to complete over the 3-day weekend. She recorded the number of problems in her math journal. She completed 39/100 of the problems on Friday,5/10 of the problems on Saturday,and another 15 problems on Sunday. Did chloe fill out her math journal correctly ?

Answers

The answer is no, Chloe did not fill out her math journal correctly.

To determine if Chloe completed all 100 math problems correctly, we need to calculate the total number of problems she completed over the weekend.

On Friday, Chloe completed [tex]\( \frac{39}{100} \)[/tex] of the problems. This fraction represents the portion of the total problems she completed on Friday. To find out how many problems this corresponds to, we multiply the total number of problems by this fraction:

[tex]\[ \text{Problems on Friday} = \frac{39}{100} \times 100 = 39 \text{ problems} \][/tex]

On Saturday, Chloe completed [tex]\( \frac{5}{10} \)[/tex] of the problems. Again, we multiply the total number of problems by this fraction to find out the number of problems completed on Saturday:

[tex]\[ \text{Problems on Saturday} = \frac{5}{10} \times 100 = 50 \text{ problems} \][/tex]

On Sunday, Chloe completed another 15 problems.

Now, we add up the problems completed each day to find the total number of problems completed over the weekend:

[tex]\[ \text{Total problems completed} = \text{Problems on Friday} + \text{Problems on Saturday} + \text{Problems on Sunday} \][/tex]

[tex]\[ \text{Total problems completed} = 39 + 50 + 15 \][/tex]

[tex]\[ \text{Total problems completed} = 104 \][/tex]

Chloe completed a total of 104 problems, which is more than the 100 problems she was supposed to complete. Therefore, she did not fill out her math journal correctly, as she recorded more problems than were assigned.

Chloé's math journal is not filled out correctly.

Let's calculate how many problems Chloé completed each day:

Friday: She completed  [tex]\frac{39}{100}[/tex]  of 100 problems, which equals 39 problems.Saturday: She completed  [tex]\frac{5}{10}[/tex]  (or 50%) of 100 problems, which equals 50 problems.Sunday: She completed 15 problems.

Adding these up: 39 (Friday) + 50 (Saturday) + 15 (Sunday) = 104 problems.

This must be incorrect since she only had 100 problems to start with. Therefore, Chloé's math journal is not filled out correctly.

In the following set, the mode is the most effective measure of central tendency if you want to emphasize how small the values are. 32, 21, 68, 21 True False

Students were divided into two groups. Students in one group were ignored when they talked without raising their hands. Students in the other group were attended to in the teacher's usual manner. The independent variable in this experiment was _____.

Answers

Answer:

The independent variable in this experiment was the attention students gets from the teacher

Step-by-step explanation:

An independent variables are variables in maths, statistics and experimental sciences that stands alone and isn't affected by the other variables you are trying to measure.

Final answer:

The independent variable was the teacher's response to the student behavior of either ignoring or attending to students when they talked without raising their hands.

Explanation:

The independent variable in this experiment was the strategy used by the teacher regarding whether or not to ignore the students when they talked without raising their hands.

In experimental design, the independent variable is the condition that is manipulated by the researcher to observe its effects on the dependent variable.

In this case, students in one group were ignored when they spoke without raising their hands, making them the experimental group.

The other group, which the teacher attended to in their usual manner, acted as the control group.

Since the independent variable is the only factor that is intentionally changed to test its impact on outcomes, observing changes in the students' behavior helped determine the effects of this teaching strategy.

walnuts cost $3.60 per pound and peanuts cost $2.70 per pound. For a fundraiser, the softball team will be selling bags of mixed nuts. How many punds of walnuts and how many pounds of peanuts should the team buy in order to make a 60 pound . ixture that will sell for $3.00 per pound?

Answers

Answer: 20 pounds of walnuts should be mixed with 40 pounds of peanuts.

Step-by-step explanation:

Let x represent the number of pounds of walnuts that should be in the mixture.

Let y represent the number of pounds of peanuts that should be in the mixture.

The number of pounds of the mixture to be made is 60. This means that

x + y = 60

Walnuts cost $3.60 per pound and peanuts cost $2.70 per pound. The mixture will sell for $3.00 per pound. It means that the total cost of the mixture is 3 × 60 = $180. The expression would be

3.6x + 2.7y = 180- - - - - - - - - - - - -1

Substituting x = 60 - y into equation 1, it becomes

3.6(60 - y) + 2.7y = 180

216 - 3.6y + 2.7y = 180

- 3.6y + 2.7y = 180 - 216

- 0.9y = - 36

y = - 36/ - 0.9

y = 40

x = 60 - y = 60 - 40

x = 20

The​ cost, in​ dollars, of producing x belts is given by Upper C (x )equals 751 plus 12 x minus 0.067 x squared. Find the rate at which average cost is changing when 256 belts have been produced.

Answers

Answer:

  -$0.07846 per belt

Step-by-step explanation:

The average cost per belt is ...

  [tex]c(x)=\dfrac{C(x)}{x}=\dfrac{751+12x-0.067x^2}{x}=751x^{-1}+12-0.067x[/tex]

Then the rate of change of average cost is ...

  [tex]c'(x)=-751x^{-2}-0.134\\\\c'(256)=\dfrac{-751}{256^2}-0.067\approx -0.07846[/tex]

The rate at which average cost is changing is about -0.078 dollars per belt.

_____

Note that the cost of producing 256 belts is -$567.91, so their average cost is about -$2.22 per belt.

Final answer:

The student is asked to calculate the rate of change of average cost for producing belts when 256 belts are produced, by finding and evaluating the derivative of the average cost function.

Explanation:

The question asks about the rate at which the average cost is changing for the production of belts given a certain cost function C(x) = 751 + 12x - 0.067x2. To find this rate when 256 belts are produced, we need to first calculate the average cost, which is C(x) divided by x, and then take the derivative of the average cost to find its rate of change. The derivative of the average cost function gives us the rate at which the average cost is changing with respect to the number of belts produced. We evaluate this derivative at x = 256 to find the specific rate of change at the production of 256 belts.

Flip a coin 25 times and keep track of the results. What is the experimental probability of landing on tails? What is the theoretical probability of landing on heads or tails?

Answers

Answer:

you must flip a coin 25 times and record it on a table for experimental. Theoretical would be 50% chance ( showing working)

Final answer:

The theoretical probability of landing on heads or tails is always 0.5 or 50%. The experimental probability of landing on tails is determined by dividing the number of times you land tails by the total number of flips. Over the long term, thanks to the Law of Large Numbers, these values tend to converge.

Explanation:

The subject of the question is the probability of landing on heads or tails when flipping a coin 25 times. The experimental probability of landing on tails can only be determined empirically by actually performing the experiment. After flipping the coin 25 times, you would calculate the experimental probability of landing on tails by dividing the number of times you landed on tails by the total number of flips (25).

On the other hand, the theoretical probability of landing on heads or tails on a single flip of a fair coin is always 0.5, or 50%, due to the nature of the coin having two equally likely outcomes. This is known as the Law of Large Numbers, which states that as the number of trials of a random experiment increases, the experimental probability approaches the theoretical probability.

For example, if we talk about Karl Pearson's experiment, after flipping a coin 24,000 times, he obtained heads 12,012 times. The relative frequency of heads is 12,012/24,000 = 0.5005, which is very close to the theoretical probability (0.5).

We would like to construct a 66% confidence interval for the proportion of voters that support building a new prison. What is the appropriate multiplier (z) that would be used in this situation?

Answers

Answer:

The appropriate z multiplier for 66% confidence interval is 0.95

Step-by-step explanation:

We are given the following in the question:

Confidence interval:

[tex]\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

We have to make a 66% confidence interval for the proportion of voters.

Confidence level = 66%

Significance level =

[tex]\alpha = 1 - 0.66 = 0.34[/tex]

[tex]z_{critical}\text{ at}~\alpha_{0.34} = \pm 0.95[/tex]

Thus, the appropriate z multiplier for 66% confidence interval is 0.95
