Answer:

x= -22/5 or -4.4

Step-by-step explanation:

Step 1- Collect like terms.

(2x-7x)-8= (10+4)

-5x-8= 14

Step 2- Add 8 to both sides.

-5x-8= 14

-5x= 22

Step 3- Divide to both sides.

-5x= 22

-5    -5

x= -22/5 or -4.4

It depends on the total distance of the trip. If the total distance is 40 km, then the trip will take 2 hours (20 km/hour + 20 km/hour). If the total distance is 60 km, then the trip will take 3 hours (30 km/hour + 30 km/hour).

Total distance = 40 km

Time for the way up = 40 km / 20 km per hour = 2 hours

Time for the way down = 40 km / 30 km per hour = 1.33 hours

Total time = 2 hours + 1.33 hours = 3.33 hours

The total time for the trip depends on the total distance. If the total distance is 40 km, then the time taken for the trip will be 3.33 hours. This is calculated by dividing the total distance by the average speed of the way up (20 km per hour) and the way down (30 km per hour). In this case, the time taken for the way up is 2 hours and the time taken for the way down is 1.33 hours, making the total time 3.33 hours.

The total number of votes cast in the city was 7864.

Given that there were 2949 no votes, which corresponds to 3 parts of the ratio.

Assume that the total number of votes as x. According to the given information, the ratio of yes votes to no votes is 5 to 3. This means that for every 5 yes votes, there are 3 no votes.

Set up the equation as given:

3 parts = 2949 votes

1 part = 2949 votes / 3

1 part = 983 votes

Now, since the ratio of yes votes to no votes is 5 to 3,  a total of 5 + 3 = 8 parts.

Total number of votes = 8 parts × 983 votes per part

Total number of votes = 7864 votes

Therefore, the total number of votes cast was 7864.

The 95% confidence interval that estimates proportion of 8th graders that are involved in an after school activity (0.745, 0.895) , the correct option is (a) .

In the question ,

it is given that ,

simple random sample of 100 8th graders is taken ,

that means ,

n = 100 ,

also given that , 82% of them are involved with some type of after school activity.

means ; p = 0.82 .

the level of significance (α) = 100 - 95 = 5% = 0.05 .

the critical value=  \(Z_{\alpha /2}\) = \(Z_{0.025}\) = 1.959964   ......from the Z table .

the lower limit of the 99% confidence interval is = p - \(Z_{\alpha /2}\)*SE

and the upper limit for the 99% confidence interval is=  p + \(Z_{\alpha /2}\)*SE  .

the standard error is √(p(1-p)/n

= √(0.82(1 - 0.82)/100

= 0.0384

So , the lower limit is ⇒ 0.82 - 1.959964*0.0384

On simplification ,

we get ,

lower limit is = 0.7447006 ≈ 0.745 .

the upper limit is =  p + \(Z_{\alpha /2}\)*SE  

= 0.82 + 1.959964*0.0384

On Simplification ,

we get ,

upper limit is = 0.8952994 ≈ 0.895 .

Therefore , the confidence interval is (0.745, 0.895) .

We need to know about composite functions to solve the problem. The value of hk^-1(x) is x-7/3.

Composite functions are functions where the output of one function is used as an input of the other function. In the given question we know the values of h(x) and k(x). We need to find the value of the inverse of the composite function of h and k. In the given function, the output of k(x) will become the input of h(x). Once we have found the composite function, we need to find the inverse of the function.

For triangle BCD, the measure of segment:

1) CD = 64 units

2) CE = 26 units

3) HD = 33 units

4) GD = 29 units

5) HG = 15.75 units

6) HF = 8.1 units

Here, H is the circumcenter of ΔBCD

We know that the circumcenter of a triangle is nothing but the point where the perpendicular bisectors of three sides of that triangle intersect.

This means that EH, FH and GH are perpendicular bisectors of three sides of ΔBCD

We know that a perpendicular bisector always divides a line segment through its midpoint.

So, for side CB, CE = EB

Here, EB = 26 units

⇒ CE = 26 units

and, CB = CE + EB

CB = 26 + 26

CB = 52 units

Similarly, for side CD of triangle BCD:

CF = FD

here, FD = 32 units

⇒ CF = 32 units

And CD = CF + FD

⇒ CD = 64 units

Similarly, for side BD of triangle BCD:

BG = GD

Here, BD = 58 units

So, GD = 1/2 (BD)

GD  = 29 units

Now, we can observe that ΔCHD is an isosceles triangle.

So, CH = HD

⇒ HD = 33 units

In triangle GHD using Pythagoras theorem,

HG = \(\sqrt{HD^2-GD^2}\)

HG = \(\sqrt{33^2-29^2}\)

HG = 15.75 units

Similarly, in triangle CFH using Pythagoras theorem,

HF = \(\sqrt{HC^2-FC^2}\)

HF = \(\sqrt{33^2-32^2}\)

HF = 8.1 units

If the sample size in part c is larger, then the sample standard deviation will be a better estimate of the population

standard deviation.  If the sample size is smaller, then the sample standard deviation will be less reliable and may not

be a good estimate of the population standard deviation.

To describe the standard deviation in part c relative to the population standard deviation from which the samples were

generated, you can use the concept of the sample standard deviation.

The sample standard deviation is a measure of the variation in a set of data that is calculated by taking the square root

of the variance of the data set. The variance is the average of the squared differences from the mean. It is important to

note that the sample standard deviation is an estimate of the population standard deviation, which is the true measure

of the variability in the population. The larger the sample size, the closer the sample standard deviation will be to the

population standard deviation. Therefore, if the sample size in part c is larger, then the sample standard deviation will

be a better estimate of the population standard deviation.

Conversely, if the sample size is smaller, then the sample standard deviation will be less reliable and may not be a

good estimate of the population standard deviation.

If rxy = 0.83, we can conclude that x and y have a relatively strong positive linear relationship or correlation.

The correlation coefficient (r) measures the strength and direction of the linear relationship between two variables, in this case, x and y. The value of r ranges between -1 and 1. A positive value indicates a positive relationship, meaning that as one variable increases, the other variable tends to increase as well.

In this case, with rxy = 0.83, the correlation coefficient is close to 1, suggesting a strong positive linear relationship. This means that when x increases, y also tends to increase, and vice versa. The closer the value of r is to 1, the stronger the linear relationship between x and y.

It is important to note that correlation does not imply causation. While a high correlation coefficient indicates a strong linear relationship, it does not provide information about the underlying cause or direction of the relationship between the variables. Other factors and variables may influence the relationship, and further analysis may be required to understand the nature of the relationship between x and y.

Everything has been explained in there

The standard deviation for the number of girls in groups of 15 couples is approximately 1.378.

The percentage of "Success" in a series of n tests, where each time a yes-or-no question is posed, the boolean-valued result is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1 p).

To find the standard deviation for the number of girls in a group of 15 couples, we can use the binomial distribution since each couple can have either a girl or a boy.

In this case, the probability of having a girl is given as 0.60, and we have 15 trials (15 couples).

The formula for the standard deviation of a binomial distribution is given by √(n * p * q), where n is the number of trials, p is the probability of success (having a girl), and q is the probability of failure (having a boy).

In this case, n = 15, p = 0.60, and q = 1 - p = 0.40.

Using the formula, the standard deviation can be calculated as:

std deviation = √(15 * 0.60 * 0.40)

std deviation ≈ 1.378 (rounded to 3 decimal places)

Therefore, the standard deviation for the number of girls in groups of 15 couples is approximately 1.378.
