Using the distance formula, we can find the distance between them as a function of time t:

Restaurateur Denny Valentine is evaluating two sites, Raymondville and Rosenberg, for his next restaurant. He wants to prove that Raymondville residents (population 1) dine out more often than Rosenberg residents (population 2). Denny commissions a market survey to test this hypothesis. The market researcher used a random sample of X families from each suburb, and reported the following:
1 = X times per month and 2 = X times per month. Assume that σ1 = 2 and σ2 = 3. With α = .01, the appropriate decision is:_________
Answer:
Step-by-step explanation:
From the information given:
let [tex]\mu_1[/tex] be the men of the population 1 (Raymondville) and [tex]\mu_2[/tex] be the mean of the population 2 (Rosenberg).
Here the Restaurateur wants to prove that Raymondville residents dine out more often than Rosenberg residents.
i.e [tex]\mu_1 > \mu _2[/tex]
The null hypothesis and alternative hypothesis:
[tex]H_o : \mu_1 \le \mu_2 \\ \\ H_a: \mu_1 > \mu_2[/tex]
[tex]H_o : \mu_1 \le \mu_2\ \ vs \ \ H_a: \mu_1 > \mu_2 \implies \text{upper tailed test}[/tex]
The shows that this test is one-tailed with the rejection area on the right side.
The appropriate decision: is to reject [tex]\mathbf{H_o}[/tex] if the test statistics is greater than the critical value)

The parameter and the statistic respectively of the given distribution are;
Parameter; μ = 2.5003
Statistic; x-bar = 2.5009
Parameter and StatisticWe are told that;
Population mean diameter; μ = 2.5003 cmSample Mean diameter; x-bar = 2.5009 cmNow, a parameter is defined as any measured quantity of a statistical population that describes an aspect of the population, such as a mean or standard deviation. These parameters are usually those that define the population such as population mean and population standard deviation.
However, the statistic is the number that describes a sample e.g, sample mean and sample standard deviation.

Complete the equation of the line through (1,4) and (2, 2).
Answer:
The equation is
[tex]y = - 2x + 6[/tex]
Step-by-step explanation:
First we find the measure
[tex]m = \frac{4 - 2}{1 - 2} = - 2[/tex]
Then the equation is
[tex]y = - 2x + c[/tex]
To find C we can usw any point
Then
[tex]2 = - 2 \times 2 + c \\ c = 6[/tex]
Then the equation is
[tex]y = - 2x + 6[/tex]
Given
mZAOC = 104°
mZAOB = 7x + 30°
mZBOC = 9x + 42°
Find mZBOC:
Answer:
The answer is 60°
Step-by-step explanation:
From looking at the problem we know that mZAOB and mZBOC make up angle mZAOC.
We also know that mZAOC is 104°
This means that the two other angles have to make up 104°
To figure out mZBOC,
First, you can subtract 30 and 42 from 104.
We do this because it allows us to focus on the variables.
104-30-42=32
Next, we can look at the variables and the coefficients and see that in order for 7x and 9x to make 32, x has to equal 2.
7(2)+9(2)=32
Now that we know what x equals we can substitute it into the equation for mZBOC.
9x + 42°
9(2) + 42°
60°
Thus, mZBOC equals 60°

The point that corresponds to the ball's maximum height on the graph is (4, 80).
How to know if a point lies in the graph of a function?All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.
Cassie hit a golf ball.
The function f models the height of the ball above the ground (in meters) as a function of time (in seconds) after Cassie hit it.
We can see from the graph that the highest point the ball could reach is 80 units.
Therefore, The point that corresponds to the ball's maximum height is (4, 80).

The least common denominator for the function [tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex] is (x -2).
What is least common denominator?The least common multiple of a group of fractions' denominators is known as the lowest common denominator, or Least Common Denominator.
Calculation for the least common denominator:
Consider the given expression,
[tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex]
Further simplifying the equation by factorisation of the denominator part
= [tex]\frac{11x}{x^{2} +6x-2x-12} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{11x}{(x+6)(x-2)} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{1}{x-2}[/tex]×[tex][\frac{11x}{(x+6)} -\frac{7}{2x}][/tex]
Therefore, from the above result, it is found that (x-2) is the least common denominator that can be taken.
