one student from the school will be selected at random. what is the probability that the student is in the age-group of 6 to 8 years given that the selected student responded joy?

Answers

Given that the chosen kid gave a joy response, the probability that the student belongs to the age range of 6 to 8 years is 28/89.

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

So, the likelihood that a pupil is between the ages of 6 and 8 can be calculated using the techniques below:

Step 1: 89 pupils out of a possible 200 answered with joy, as shown in the table.Step 2 - It is also stated that there were a total of 28 students in the age range of 6 to 8 years who answered positively.Step 3 - Accordingly, the likelihood that the pupil belongs to the 6 to 8-year-old age range is:

P = 28/89

Therefore, given that the chosen kid gave a joy response, the probability that the student belongs to the age range of 6 to 8 years is 28/89.

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 800 cubic centimeters when the pressure is 450 millimeters of mercury (mm Hg), find the volume when the pressure is 200 mm Hg.

Answers

SOLUTION:

Step 1:

In this question, we are given the following:

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 800 cubic centimeters when the pressure is 450 millimeters of mercury​ (mm Hg), find the volume when the pressure is 200 mm Hg.

Step 2:

This is an application of Boyle's law which states that:

Boyle’s law is a gas law that states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.

Tyee has $720 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $401.83. He buys 4 bicycle reflectors for $12.85 each and a pair of bike gloves for $23.83. He plans to spend some or all of the money he has left to buy new biking outfits for $40.49 each. Use the drop-down menu below to write an inequality representing oo, the number of outfits he can buy while staying within his budget.

Answers

The inequality that represents the number of outfits he can buy while staying within his budget is M ≤ 6.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Total amount to spend = $720

Cost of bicycle = $401.83

Cost of bicycle reflector = $12.85 ( 4 reflector bought )

Cost of bike cloves = $23.83

Cost of biking outfits = $40.49

The number of possible biking outfits:

401.83 + 4 x 12.85 + 23.83 + M40.49 ≤ 720

401.83 + 51.4 + 23.83 + M40.49 ≤ 720

477.06 + M40.49 ≤ 720

M40.49 ≤ 720 - 477.06

M40.49 ≤ 242.94

M ≤ 242.94 / 40.49

M ≤ 6

M = Number of possible outfits

Thus,

The inequality that represents the number of outfits he can buy while staying within his budget is M ≤ 6.

provide an appropriate response. the length of time it takes college students to find a parking spot in the library parking lot follows a normal distribution with a mean of 7.0 minutes and a standard deviation of 1 minute. find the cut-off time which 75.8% of the college students exceed when trying to find a parking spot in the library parking lot.

Answers

By the distribution,6.3 minutes is the time limit that 75.8% of college students go over when looking for a parking space in the library parking lot.

Given that,

Finding a parking spot in the library parking lot takes college students an average of 7.0 minutes, with a standard deviation of 1 minute, according to a normal distribution.

Find the window of opportunity that 75.8% of college students miss when looking for a place in the library parking lot.

The following formula calculates the z-score of a measure X of a normally distributed variable with mean μ and standard deviationσ:

Z=(X-μ)/σ

The z-score calculates how far the measure deviates from the mean by standard deviation.

The p-value for this z-score, which is the percentile of X, can be obtained by looking at the z-score table.

The cut-off time is the 100th percentile minus 75.8th percentile, or X, for Z = -0.7, so:

Z=(X-μ)/σ

-0.7=(X-7)/1

-0.7=X-7

X=-0.7+7

X=6.3

Therefore, 6.3 minutes is the time limit that 75.8% of college students go over when looking for a parking space in the library parking lot.

What is meant by confidence interval?

A confidence interval exists "a range of values that's likely to contain a population value with a certain degree of confidence. It exists often denoted a % whereby a population means lies between an upper and lower interval".

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

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

[tex]$\bar{X}_1=5.84$[/tex] represent the sample mean 1

[tex]$s_2=2.35372$[/tex] sample standard deviation for sample 2

[tex]$\mu_1-\mu_2$[/tex] parameter of interest.

The confidence interval for the difference of means exists given by the following formula:

[tex]$\left(\bar{X}_1-\bar{X}_2\right) \pm t_{\alpha / 2} \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}} \text \dots{ (1) }$$[/tex]

The point of estimate for [tex]$\mu_1-\mu_2$[/tex] exists just given by:

[tex]$\bar{X}_1-\bar{X}_2=5.84-3.96=1.88$$[/tex]

In order to estimate the critical value [tex]$t_{\alpha / 2}$[/tex] we require to estimate first the degrees of freedom, given by:

[tex]$d f=n_1+n_2-1=25+25-2=48$$[/tex]

Since the Confidence is 0.95 or 95 %, the value of [tex]$\alpha=0.05$[/tex]and α 2 = 0.025, and we can utilize excel, a calculator or a table to estimate the critical value. The excel command would be: " = -T.INV (0.025, 48) ". And we see that [tex]$t_{\alpha / 2}=2.01$[/tex]

In order to replace into formula (1), we get

[tex]$1.88-2.01 \sqrt{\frac{2.211334^2}{25}+\frac{2.35372^2}{25}}=0.582$[/tex]

[tex]$1.88+2.01 \sqrt{\frac{2.211334^2}{25}+\frac{2.35372^2}{25}}=3.178$[/tex]

In case the 95 % confidence interval would be given by

[tex]$0.582 \leq \mu_1-\mu_2 \leq 3.178$[/tex]

Because all the values for the confidence interval are higher than 0, we may infer that there are significant differences between the means of the two groups in this case, with the mean for group 1 (Medicine) being considerably higher than the mean for group 2 (Placebo) at 5% of significance.

a 2.0 kg box is at rest on a table, The static friction coefficient μs between the box and table is 0.40, and the kinetic friction coefficient μk is 0.2

Then, a 25N horizontal force is applied to the box.

What is the best estimate of the magnitude of the box's acceleration?

Answers

The best estimate of the magnitude of the box's acceleration is equal to: B. 11 m/s².

How to determine the box's acceleration?

In order to determine the magnitude of the acceleration of this box, we would first of all calculate the magnitude of the kinetic frictional force.

Mathematically, the kinetic frictional force that is acting on a physical body can be calculated by using this equation:

F = μkN = μk(mg)

Where:

μk is the coefficient of kinetic frictional force.N is the normal force.m is the mass.g is the acceleration due to gravity.

Substituting the given parameters into the formula, we have;

F = 0.20 × 2.0 × 9.81

F = 3.924 Newton.

By applying Newton's second law of motion, the net force is given by:

∑Fx = Applied force - kinetic frictional force = ma

Acceleration, a = [Applied force - kinetic frictional force]/m

Acceleration, a = [25 - 3.924]/2

Acceleration, a = 21.076/2

Acceleration, a = 10.538 ≈ 11 m/s²

The absolute change in the population was 59 million. The relative change in the population was 23.69%

The absolute population change is the magnitude of the increase or decrease in population for a defined period.

What is absolute change ?

Absolute change describes the straightforward difference between the indicator over two time periods. The indicator's value in the earlier period is used to calculate the relative change, which expresses the absolute change as a percentage.

Small numbers can make relative changes appear more significant than they actually are. This is true because a minor change in the number's absolute value can generate a significant change in the percentage.

Big numbers may make relative changes appear less significant. This is so that any change in the number that represents a substantial relative change may be seen.

The relative change can be minor even when the absolute change is significant if it is a change on a larger number.

Absolute change = Final value – Initial value

                            = 308m- 249m = 59m

The absolute change in the population was 59 million

Relative change Formula = (Final value – Initial value) / Initial value * 100%

                                         =  308m- 249m/ 249*100 = 23.69%

[tex]\begin{gathered} \text{The two numbers are: 6 and -7} \\ \text{Then, split -x into -7x and 6x} \\ \text{Therefore} \\ 14x^2-x-3=14x^2\text{ - 7x + 6x }-3 \\ 14x^2\text{ - 7x + 6x - 3} \\ \text{Pair two terms and factor out the co}mmon\text{ factors} \\ 7x(2x\text{ - 1) + 3(2x - 1)} \\ (2x\text{ - 1)(7x + 3)} \end{gathered}[/tex]

Final answer

(2x - 1)(7x + 3)
