Every 125 pages that Raul reads during his summer reading challenge, he will collect 5 book points to use at his local library.
monitta

Answer:

The answer is "\frac{1}{25}"

Step-by-step explanation:

They might claim that perhaps the ratio to Raul would've been:\frac{y}{x} = \frac{5}{125} = \frac{1}{25} per each 125(x) page, which he reviewed throughout a summer competition.

Raul's cost per unit for each paragraph reads is \frac{1}{25} page points, that's why the model a link with the same unit rate. please find the graph in the attached file.

A researcher studying reaction time of drivers states that, "A 95% confidence interval for the mean time it takes for a driver t
torisob [31]

Answer:

The answer to the question is

Point Estimate = 1.5

Margin of error = 0.3

Step-by-step explanation:

A point estimate as opposed to an interval estimate, presented in the question which consist of a range of values, is a specific point or single value to describe a given set of collected data. An example of a point estimate is the mean of a range of values hence the point estimate is given as

(1.2 + 1.8) ÷ 2 which is equal to 1.5

The margin of error is used to describe the required allowance in terms of statistical points or percentage points by which a given set of result could vary from the actual sample. It represents the expected error between the actual population and the survey result

In this case the margin of error from the mean  is

1.5 - 1.2 = 0.3

Margin of error formula is z ×σ/√(n)

where z = z-score

σ = standard deviation

n = number of sampled data

In a volatile housing market, the overall value of a home can be modeled by V(x)=325x2-4600x+145000, where V represents the valu
shtirl [24]

Answer:

The vertex of the given equation is    which shows that the value of the market after about 5 years is about 187,253.01

Functions and values

Given the overall value of a home can be modeled by

V(x) = 415x^2 – 4600x + 200000

Write in vertex form to have:

V(x) = 415x^2 – 4600x + 200000

For the given equation, the vertex occur at

Hence the vertex of the given equation is    which shows that the value of the market after about 5 years is about 187,253.01
