I need help with geometry problems
Show ALL work and explain the processes of each***1. A label on an iced tea drink mix says to use 2 tbsp of iced tea mix to make one serving (8 oz) of iced tea.a. What is the ratio of drink mix to iced tea? (Hint: 1 oz = 2 tbsp)b. Suppose you want to make a quart (32 oz) of iced tea. How many ounces of drink mix should be used?c. How many tablespoons of iced tea mix should be used to make a quart (32 oz) of iced tea?2. △ RST has coordinates R(-4, -3), S(0, 5), and T(7, -3).a. Graph △ RST in a coordinate plane.b. Find the perimeter of △ RST.c. Find the area of △ RST.d. The centroid of a triangle is the intersection of its medians. Use the following steps to find the centroid of △ RST using segment partition.i. Find the midpoint of . Label it N.ii. Find the point, C, that partitions such that SC:CN has a ratio of 2:1 .iii. Plot point C in your graph of △ RST.e. Find and graph the midpoints of , ,and . Draw a segment connecting the vertex opposite each midpoint to the midpoint.i. How does the intersection of the segments compare to point C from question 4?3. Brian is renting an apartment. The floor plan of the apartment is shown below.a. What is the total area of the apartment?b. What are the dimensions of the master bedroom?c. Brian wants to buy a dining room table from the local furniture store.

A major
financial services company wishes to better understand its mortgage
approval process. In particular, the company is interested in learning
about the effects of credit history (good versus fair), the size of the
mortgage (<$500,000 versus >$500,000), and the region of the
United States (western versus eastern) on the amount of time it takes to
get a mortgage approved. The database of mortgages approved in the last
year is accessed, and a random sample of five approved mortgages is
selected for each of the eight combinations of the three variables. The
data are shown in the table

Maricopa Community Colleges Statistics Questions
A social worker notes that in a population of psychiatric inpatients the ethnic mix seems out of balance with what she has understood to be the ratios in the general population. Respond to the prompts below to show how she might determine whether the inpatient ethnic mix varies from the mix in the general population. (1 point each)
What statistical test would be appropriate to use here? Explain the rationale for your answer.
What assumptions would need to be met in order to use the test?
Describe the data that the test would be based on as either quantitative or qualitative. Explain the rationale for your answer.
Write an example of how the null and alternative hypotheses for this test could be stated.
What would the researcher need to know in order to calculate the appropriate test statistic? I.e., what values need to be known or calculated in order to complete the calculation of the test statistic?
Given a data set that can be graphed as a standard normal curve, respond to the prompts below. (1 point each)
What defines the graph? I.e., what determines the shape of the graph and what is the relationship between these defining characteristics?
What must be done in order to transform a normal distribution of data into a standard normal distribution based on the same data?
What is the advantage of having transformed data so that it can be represented by a standard normal distribution?
We often see data points represented by either x or z. What is the relationship between them?
Why is the area under the standard normal curve above the mean always the same value?
A school psychologist wants to determine whether children who live with both parents perform better on school work than children who live with a single parent. She gathers two groups for her comparison, 20 children who live with both parents and another 20 who live with a single parent. The psychologist plans to use scores on a standardized achievement test as an indicator of school performance. Respond to the prompts below.
What statistical test would be appropriate in this case? Explain the rationale for your answer.
Identify the independent variable in this study.
Identify the dependent variable in this study.
Describe a potentially confounding variable and explain how that might affect the conclusions from the study.
State the null and alternative hypotheses in words.
A team of psychologists have developed an experimental treatment program for a learning disorder with the expectation that the treatment would enable recipients to score higher than before on a test of learning ability. To test the treatment, they randomly select a pool of 30 volunteers who have been diagnosed with the disorder and who have volunteered for the treatment program. Following treatment, the participants are retested on the learning ability test and their scores compared to earlier scores. Complete the following.
What statistical test would be appropriate in this case? Explain the rationale for your answer.
State the null and alternative hypotheses in words.
State the null and alternative hypotheses in statistical symbols
Would the test be right-tailed, left-tailed or two-tailed? Explain the rationale for your answer.
