. using social media in a job search. according to inc, 79% of job seekers used social media in their job search in 2018. many believe this number is inflated by the proportion of 22- to 30-year-old job seekers who use social media in their job search. a survey of 22- to 30-year-old job seekers showed that 310 of the 370 respondents use social media in their job search. in addition, 275 of the 370 respondents indicated they have electronically submitted a resume to an employer. a. conduct a hypothesis test to determine if the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that use social media in their job search. use a 5 .05. b. conduct a hypothesis test to determine if the results of the survey justify concluding that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. using a 5 .05, what is your conclusion?
In case of (a) Since 3.41 > 1.64485, we reject the null hypothesis and conclude that the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that uses social media in their job search. And in (b) 2.01 > 1.64485, we reject the null hypothesis and conclude that the results of the survey justify concluding that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer.
a. To conduct the hypothesis test for the proportion of 22- to 30-year-old job seekers who use social media in their job search, we need to set up the null and alternative hypotheses:
H0: p = 0.79 (the proportion of 22- to 30-year-old job seekers who use social media is equal to the proportion of the population that use social media in their job search)
Ha: p > 0.79 (the proportion of 22- to 30-year-old job seekers who use social media is greater than the proportion of the population that use social media in their job search)
Where p is the true proportion of 22- to 30-year-old job seekers who use social media.
We can use a one-sided z-test for proportions to test the hypothesis. The test statistic is calculated as: z = (p1 - p) / sqrt(p * (1 - p) / n)
where p1 = 310/370 = 0.838 and n = 370.
Using a significance level of 0.05, we can find the critical value from the standard normal distribution table to be 1.64485.
If the calculated z-value is greater than the critical value, we reject the null hypothesis.
z = (0.838 - 0.79) / sqrt(0.79 * (1 - 0.79) / 370) = 3.41
Since 3.41 > 1.64485, we reject the null hypothesis and conclude that the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that uses social media in their job search.
b. To conduct the hypothesis test for the proportion of 22- to 30-year-old job seekers who have electronically submitted a resume, we need to set up the null and alternative hypotheses:
H0: p = 0.70 (the proportion of 22- to 30-year-old job seekers who have electronically submitted a resume is equal to 70%)
Ha: p > 0.70 (the proportion of 22- to 30-year-old job seekers who have electronically submitted a resume is greater than 70%)
Where p is the true proportion of 22- to 30-year-old job seekers who have electronically submitted a resume.
We can use a one-sided z-test for proportions to test the hypothesis. The test statistic is calculated as:
z = (p1 - p) / sqrt(p * (1 - p) / n)
where p1 = 275/370 = 0.743 and n = 370.
Using a significance level of 0.05, we can find the critical value from the standard normal distribution table to be 1.64485.
If the calculated z-value is greater than the critical value, we reject the null hypothesis.
z = (0.743 - 0.70) / sqrt(0.70 * (1 - 0.70) / 370) = 2.01
Since 2.01 > 1.64485, we reject the null hypothesis and conclude that the results of the survey justify concluding that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer.
Therefore, In case of (a) Since 3.41 > 1.64485, we reject the null hypothesis and conclude that the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that uses social media in their job search.

find the solution of the initial value problem y'' 2y' 5y = 12e^-t cos(2t), y(0) = 10, y'(0) = 0
The solution to the initial value problem is:y(t) = (10 - (12/7))e^(t) cos(2t) + (12/7)e^(-t) cos(2t).
The characteristic equation of this linear second order ordinary differential equation is:
m^2 - 2m + 5 = 0
The roots of this characteristic equation are m = 1 ± 2i, which means the general solution to the homogeneous equation is:
y(t) = c1e^(t) cos(2t) + c2e^(t) sin(2t)
To find the particular solution, we can use the method of undetermined coefficients and guess that yp(t) = Ae^(-t) cos(2t) + Be^(-t) sin(2t).
Substituting this into the differential equation, we get:
2Ae^(-t) cos(2t) - 2Ae^(-t) sin(2t) + 5Ae^(-t) cos(2t) - 5Be^(-t) sin(2t) = 12e^(-t) cos(2t)
Comparing coefficients, we have:
2A - 2A + 5A = 12
7A = 12
A = 12/7
-5B = 0
B = 0
So the particular solution is:
yp(t) = (12/7)e^(-t) cos(2t)
The general solution to the non-homogeneous equation is then:
y(t) = c1e^(t) cos(2t) + c2e^(t) sin(2t) + (12/7)e^(-t) cos(2t)
Using the initial conditions, we can find the values of c1 and c2:
y(0) = 10 = c1 + (12/7)
c1 = 10 - (12/7)
y'(0) = 0 = c2e^(0) sin(0)
c2 = 0
Therefore, the solution to the initial value problem is: y(t) = (10 - (12/7))e^(t) cos(2t) + (12/7)e^(-t) cos(2t)

parallel, perpendicular,
or neither.
2. AB formed by (3, 7) and (-6, 1)
CD formed by (-6, -5) and (0, -1)
Answer: ez, the answer is Parallel
Step-by-step explanation:
because ab and cd are parallel lines
AB is formed by (3,7) and (-6, 1)
CD is formed by (-6,-5) and (0,-1)
testing the two lines are parallel or perpendicular or neither, is done by determining their gradients
Triangle AB = Gradient of AB = Triangle Y over triangle X = 1-7 over -6-3 = -6 over -9 = 2/3
Triangle CD = Gradient of Triangle CD = Triangle Y over Triangle X = -1 - -5 over 0 - -6 = 1 + 5 over 0 + 6 = 4 over 6 = 2/3
So the two lines AB and CD have the same gradient and thus the two lines are PARALLEL to each other.

when you are looking at a figure, when can you say on average? why?
When talking about a figure, you can say "on average" when you are discussing a measure of central tendencies, such as the mean, median, or mode.
This is because these measures represent the "average" point in the data set. For example, if you are looking at a figure that consists of the average monthly temperatures for a given region, the mean would be the average temperature (on average) for that region.
Similarly, if you are looking at a figure that consists of the average daily prices of a certain stock, the mean would be the average daily price (on average) for that stock. In either case, the mean is the "average" point in the data set.

illustrate the net force f1 f2 as the geometric addition of the two force vectors. (b) compute the net force, the vector sum of the force vectors.
The magnitude of the net force is 149.33 N.
a) To illustrate the net force F1 + F2 as a geometric addition of the two force vectors, we can use the tail-to-tip method to add the vectors head-to-tail and then connect the tail of the first vector to the tip of the second vector to form the net force vector.
b) To compute the net force as the vector sum of the two force vectors, we can use the components of the two vectors to find the components of the net force. Using the trigonometric relationship between the angle and the components of a force vector, the x and y components of the force vectors can be calculated as follows:
F1x = F1 * cos(30) = 86.6025 N
F1y = F1 * sin(30) = 50 N
F2x = F2 * cos(45) = 35.3553 N
F2y = F2 * sin(45) = 35.3553 N
The x and y components of the net force are found by adding the corresponding components of the individual force vectors:
Fnetx = F1x + F2x = 86.6025 N + 35.3553 N = 122 N
Fnety = F1y + F2y = 50 N + 35.3553 N = 85.3553 N
c) To compute the magnitude of the net force, we use the Pythagorean theorem to find the magnitude from the components:
Fnet = √(Fnetx² + Fnety²) = √(122² + 85.3553²) = 149.33 N
So, the magnitude of the net force is 149.33 N.

suppose you ask a friend to randomly choose an integer between 1 and 10, inclusive. what is the probability that the number will be more than 7 or odd? (enter your probability as a fraction.)
The probability that the number will be more than 7 or odd is 7/10.
The number more than 7 or odd is 1, 3, 5, 7, 8, 9, 10
So probability of 7 number is,
P(A) = number of favorable outcomes of an event / total number of events occurring in a sample
P(A) = 7/10
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

Solving the provided question, we can say that the highest number bouquets she can make without having any flowers left is calculated by Highest Common Factor so, HCF of 56, 48 and 16 is 8
What is Highest Common Factor?In mathematics, the highest positive integer that divides the corresponding integers is known as the greatest common divisor of two or more non-zero integers. The greatest common factor (HCF) of two or more numbers is the sum of those two or more numbers. As a result, it is frequently referred to as the largest common divisor (GCF). Take the prime factors of the two (or more) integers and determine the shared prime factors to determine the greatest common divisor. Following that, the sum of common prime factors is the greatest common divisor. A specified number divided by the biggest integer results in the greatest common divisor.

flight 202's arrival time is normally distributed with a mean arrival time of 4:30 p.m. and a standard deviation of 15 minutes. find the probability that a randomly chosen arrival time is within the given time period
The required probability is 0.953.
We know that the mean μ is:
μ = 4:30 p.m.
The standard deviation is:
σ = 0:15 minutes
The Z-score is: Z = (x-μ)/σ
We seek to find probability P(4:00 p.m. < x < 5:00 p.m.)
The Z-score is:
Z = (x-μ)/σ = 4:00 - 4:30/0:15 = -2
The score of Z =-2 means that 4:00 p.m. is -2 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the condition of 2 deviations from the mean has percentage of 2.35% and
Z = (x-μ)/σ = 5:00 - 4:30/0:15 = 2
The score of Z =2 means that 11:00 p.m. is 2 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the condition of 2 deviations from the mean has percentage of 2.35%.
∴ P(4:00 p.m. < x < 5:00 p.m.) = 100% - 2.35% - 2.35%
= 95.3% = 0.953

1. What is the minimum number of divisions made by Euclid's algorithm among all inputs 1 Sab S 10? Give your answer as a number. 2. What is the maximum number of divisions made by Euclia's algorithm among all inputs 1 € ab 10? (to answer this question, check the algorithm's performance on all pairs 1 Sa, bs 10). Give your answer as a number.
The minimum amount of number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 0, as the greatest common divisor of any two numbers between 1 and 10 must be 1. The maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19, as the greatest common divisor of 8 and 10 requires 19 divisions.
Euclid's algorithm is an efficient method for finding the greatest common divisor (GCD) of two integers. It works by repeatedly dividing larger numbers by smaller numbers until the remainder is 0. The GCD of two integers is then equal to the smaller number. The minimum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 0, as the GCD of any two numbers between 1 and 10 must be 1. This is because any two numbers between 1 and 10 have only 1 as their common divisor. On the other hand, the maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19, as the GCD of 8 and 10 requires 19 divisions. This is due to the fact that 8 and 10 have no common divisors except for 1, so the algorithm must divide 8 by 10 repeatedly until the remainder is 0. Thus, the maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19.

How do you find a formula for the general term an of the sequence?
A sequence is characterised as one that adheres to a predetermined pattern. The following term is created by increasing or decreasing the previous word by a certain amount.
On occasion, an expression is followed by every term in the series. The general formula for an AP is T n = a + (n - 1) d.
What does the sequence's general word mean?Understanding the underlying pattern or rule that creates the sequence is necessary for formulating the general term an of the sequence. Finding a formula for the overall term of a series can be done in a number of ways, including:
1) Finding a pattern: In some cases, a pattern can be found by examining the terms of the sequence and looking for a common ratio or difference. For instance, the formula for the general term can be written as a = a1 + (n - 1)d, where a1 is the first term and d is the common difference, assuming the terms of a sequence are rising by a constant amount.
2) Recurrence relations are used to characterise some sequences. These relations define the nth term in terms of the phrases that came before it. If the recurrence relation, for instance, is a = an-1 + an-2, then the general term's formula can be discovered by resolving the recurrence relation.
3) Making use of generating functions: Sequences can be represented mathematically using generating functions. A formula for the general term of a sequence can be discovered by fiddling with the generating function.

For circular motion on a circle of radius r, linear speed equals angular speed divided by r. (T/F)
For circular motion on a circle of radius r, linear speed equals angular speed divided by r. This statement is false.
What is angular speed?
The definition of angular speed is the rate at which angular displacement changes, and it is written as follows -
ω = θ/t
where θ is the angular displacement, t is the time and ω is the angular speed.
The statement says that for circular motion on a circle of radius r, linear speed equals angular speed divided by r.
Consider that an object moves around a circle of radius r at a constant speed v.
If s is the distance travelled in time t around the circle then linear speed v is defined as v = s/t.
Also if θ is the angle swept out by this object in time t then the angular speed is defined as ω = θ/t.
Thus, there is some relationship between linear speed and angular speed -
Linear speed = v = s/t
= rθ/t = r(θ/t) = rω
where is ω measured in radians per unit time and for a circle of radius r, a central angle of radians subtends an arc whose length s is s = rθ.
Hence, notice that linear speed is equal angular speed multiplied, not divided, by r.
