Answer:

a = 35°

Step-by-step explanation:

The sum of the measure of the given three angles add up to 180°.

To find the m < a:

m < a + 90° + 55° = 180°

m < a + 145° = 180°

Subtract 145° from both sides to isolate m < a:

m < a + 145° -  145° = 180° -  145°

m < a = 35°

In order for a triangle to be rotated in a symmetry that involves each rotation to matching vertices of the triangle, involves several of the options given in the list:

* All sides have the same length (we are dealing with an equilateral triangle)

* All angles ofthe triangle have the same measure (60 degrees each angle)

* A rotation of 60 degrees will map the traingle to itself (typical for a case of equilateral triangle)

* A rotation of 120 degrees will map the triangle with itself. (also in agreement with the answer immediately above, since 120 degree rotetion is the same as two consecutive 60 degree rotations)

The graph of the function g(x) = x + 3 is a straight line that passes through the point (0, 3) on the y-axis and has a slope of 1.

To understand how to plot the graph, let's consider a few points on the line.

We can choose any values for x and calculate the corresponding values for g(x).

Let's start with x = 0.

Substituting this value into the function, we get g(0) = 0 + 3 = 3.

So, the point (0, 3) is on the graph.

Next, let's choose x = 1.

Substituting this value into the function, we get g(1) = 1 + 3 = 4.

This gives us another point on the line, (1, 4).

Similarly, we can choose more values for x and calculate the corresponding values for g(x).

For example, if we let x = -1, we get g(-1) = -1 + 3 = 2, giving us the point (-1, 2).

By connecting these points and extending the line in both directions, we obtain a straight line that represents the graph of g(x) = x + 3.

The line has a positive slope of 1, which means it rises by 1 unit vertically for every 1 unit it moves horizontally.

Overall, the graph of g(x) = x + 3 is a straight line that passes through the point (0, 3) and has a slope of 1.

Using the t-distribution, it is found that since the p-value of the test is 0.72 > 0.05, there is not significant difference between the values of each group.

At the null hypothesis, we test if the groups have the same values, that is, the subtraction of their means is 0:

\(H_0: \mu_2 - \mu_1 = 0\)

At the alternative hypothesis, we test if the groups have different values, that is, the subtraction of their means is different of 0:

\(H_1: \mu_2 - \mu_1 \neq 0\)

First, we have to find the mean and the standard deviation for both samples, hence, using a calculator:

\(\mu_1 = 18.75, \sigma_1 = 6.2507, \mu_2 = 19.75, \sigma_2 = 4.2678\)

The standard errors are:

\(s_1 = \frac{\sigma_1}{\sqrt{n_1}} = \frac{6.2507}{\sqrt{8}} = 2.21\)

\(s_2 = \frac{\sigma_2}{\sqrt{n_2}} = \frac{4.2678}{\sqrt{8}} = 1.5089\)

For the distribution of differences, we have that:

\(\overline{x} = \mu_2 - \mu_1 = 19.75 - 18.75 = 1\)

\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{2.21^2 + 1.5089^2} = 2.676\)

We have the standard deviation for the samples, hence, the t-distribution is used. The test statistic is given by:

\(t = \frac{\overline{x} - \mu}{s}\)

In which \(\mu\) is the value tested at the null hypothesis, which is 0 for this problem. Hence, the value of the test statistic is:

\(t = \frac{\overline{x} - \mu}{s}\)

\(t = \frac{1 - 0}{2.676}\)

\(t = 0.37\)

To find the p-value, we have a two-tailed test, as we test if the means are different from a value, with t = 0.37 and 8 + 8 - 2 = 14 df.

Using a t-distribution calculator, this p-value is of 0.72.

Since the p-value of the test is 0.72 > 0.05, there is not significant difference between the values of each group.

Answer:

The standard deviation is of 8.586.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they have a genetic mutation, or they do not. The probability of a person having the mutation is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The standard deviation of the binomial distribution is:

\(\sqrt{V(X)} = \sqrt{np(1-p)}\)

About 9% of the population has a particular genetic mutation.

This means that \(p = 0.09\)

900 people are randomly selected.

This means that \(n = 900\)

Find the standard deviation for the number of people with the genetic mutation in such groups of 900.

\(\sqrt{V(X)} = \sqrt{900*0.09*0.91} = 8.586\)

The standard deviation is of 8.586.

The distance covered by the Passenger train is 528 miles.

We have situation in which a passenger train left a station traveling East at 88 mph and at the same time, a freight train left the same station traveling West at 70 mph.

We have to determine when the freight train is at 420 miles from the station, how far, in miles, is the passenger train from the station.

The time taken can be calculated using the formula -

t = d/v

According to question, we have ;

For freight train,

Speed = 70  mph

Distance = 420 miles

Therefore, the time taken will be;

t = 420/ 70 = 6 hours

For passenger train,

The freight train moved for 6 hours. Since, both of them started at the same time, therefore,

d = speed of passenger train x time taken by freight train to move 6 hours.

d = 88 x 6 = 528 miles

Hence, the distance covered by the Passenger train is 528 miles.

The type of model that best fits the situation of a $500 raise in salary each year is a linear model.

In a linear model, the dependent variable changes a constant amount for constant increments of the independent variable.

In the given case, the dependent variable is the salary and the independent variable is the year.

You may build a table to show that for increments of 1 year the increments of the salary is $500:

Year         Salary        Change in year         Change in salary

2010           A                           -                                       -

2011           A + 500     2011 - 2010 = 1          A + 500 - 500 = 500

2012          A + 1,000   2012 - 2011 = 1          A + 1,000 - (A + 500) = 500

So, you can see that every year the salary increases the same amount ($500).

In general, a linear model is represented by the general equation y = mx + b, where x is the change of y per unit change of x, and b is the initial value (y-intercept).              

In this case, m = $500 and b is the starting salary: y = 500x + b.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).  Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.

Abigail and Curtis Siebert have a $270,000 mortgage at an interest rate of 7% for a term of 20 years.

To calculate the monthly mortgage payment, we can use the formula for an amortizing mortgage:

M = P * (r * (1 + r)^n) / ((1 + r)^n - 1),

where M is the monthly mortgage payment, P is the principal amount (loan amount), r is the monthly interest rate, and n is the total number of monthly payments.

First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is 7% divided by 12, which is approximately 0.5833%.

The total number of monthly payments is the term of the mortgage multiplied by 12. In this case, it's 20 years * 12 months, which equals 240 months.

Now, we can substitute the values into the formula:

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).

Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.
