2) The mean mathematics SAT score in 2012 was 514 with a standard deviation of 117 ("Total group profile," 2012). Assume the mathematics SAT score is normally distributed. a. State the random variable. b. Find the probability that a person has a mathematics SAT score over 700. c. Find the probability that a person has a mathematics SAT score of less than 400. d. Find the probability that a person has a mathematics SAT score between a 500 and a 650. e. Find the mathematics SAT score that represents the top 1% of all scores.
The mathematics SAT score representing the top 1% of all scores is approximately 780.
a. The random variable in this case is the mathematics SAT score.
b. To find the probability that a person has a mathematics SAT score over 700, we need to calculate the z-score first.
The z-score is calculated as \(\frac{(X - \mu )}{\sigma}\),
where X is the value we're interested in, μ is the mean, and σ is the standard deviation.
In this case, X = 700, μ = 514, σ = 117.
Using the formula, the z-score is \(\frac{(700 - 514)}{117 } = 1.59\).
To find the probability associated with this z-score, we can consult a standard normal distribution table or use a calculator.
The probability is approximately 0.0564 or 5.64%.
c. To find the probability that a person has a mathematics SAT score of less than 400, we again calculate the z-score using the same formula.
X = 400, μ = 514, and σ = 117.
The z-score is \(\frac{(400 - 514) }{117 } = -0.9744\).
Looking up the probability associated with this z-score, we find approximately 0.1635 or 16.35%.
d. To find the probability that a person has a mathematics SAT score between 500 and 650, we need to calculate the z-scores for both values.
Using the formula, the z-score for 500 is \(\frac{(500 - 514)}{117 } = -0.1197\),
and the z-score for 650 is \(\frac{(650 - 514)}{117 } = 1.1624\).
We can then find the area under the normal curve between these two z-scores using a standard normal distribution table or calculator.
Let's assume the probability is approximately 0.3967 or 39.67%.
e. To find the mathematics SAT score that represents the top 1% of all scores, we need to find the z-score corresponding to the top 1% of the standard normal distribution.
This z-score is approximately 2.33.
We can then use the z-score formula to calculate the corresponding SAT score.
Rearranging the formula,
\(X = (z \times \sigma ) + \mu\),
where X is the SAT score, z is the z-score, μ is the mean, and σ is the standard deviation.
Substituting the values,
\(X = (2.33 \times 117) + 514 = 779.61\).
Rounded to the nearest whole number, the mathematics SAT score representing the top 1% of all scores is approximately 780.

According to Beautiful Bride magazine, the average age of a groom is now 26.2 years. A sample of 16 prospective grooms in Chicago revealed that their average age was 26.6 years with a standard deviation of 5.3 years. At a=0.05, what is the test value?
Answer:
0.3019
Step-by-step explanation:
Null hypothesis: the average age of a groom is now 26.2 years.
Alternative hypothesis: the average age of a groom is not 26.2 years.
We have a sample of 16 so we will use a t-test
Where t score = (x-u)/(sd/√n)
Where x = 26.6, u=26.2, sd= 5.3 and n=16
t score = (26.6-26.2) / (5.3/√16)
t = 0.4/(5.3/4)
t = 0.4/1.325
t = 0.3019

Express in terms of logarithms of x, y, z, or w.
a. log_7(xz)
b. log_7(y/x)
c. log_7(cube root of z)
Answer:
a.\(\bold{log_7(xz) = log_7(x * z) = log_7(x) + log_7(z)}\)
b.\(\bold{log_7(\frac{x}{y}) = log_7(y) - log_7(x)}\)
c.\(\bold{log_7(\sqrt[3]{7} ) = log_7(z^{\frac{1}{3}}) = \frac{1}{3}log_7(z)}\)
Step-by-step explanation:
let me provide an explanation for each of the expressions.
a. To express log_7(xz) in terms of logarithms of x and z, we use the logarithmic property that states log(a * b) = log(a) + log(b). Applying this property, we get:\(\bold{log_7(xz) = log_7(x * z) = log_7(x) + log_7(z)}\)
b. To express log_7(y/x) in terms of logarithms of y and x, we use the logarithmic property that states log(a / b) = log(a) - log(b). Applying this property, we get:\(\bold{log_7(\frac{x}{y}) = log_7(y) - log_7(x)}\)
c. To express log_7(cube root of z) in terms of the logarithm of z, we use the logarithmic property that states log(a^(n)) = n * log(a), where n is a constant. Applying this property, we get:\(\bold{log_7(\sqrt[3]{7} ) = log_7(z^{\frac{1}{3}}) = \frac{1}{3}log_7(z)}\)
Therefore, we can express each of the given expressions in terms of logarithms of x, y, z, or w using the logarithmic properties mentioned above.
Answer:
\(\textsf{a.} \quad \log_7(x) + \log_7(z)\)
\(\textsf{b.} \quad \log_7(y) - \log_7(x)\)
\(\textsf{c.} \quad \dfrac{1}{3}\log_7(z)\)
Step-by-step explanation:
We can express the given logarithmic expressions in terms of x, y, z or w by using the laws of logarithms.
\(\hrulefill\)
Part (a)\(\boxed{\begin{array}{c}\underline{\textsf{Product law}}\\\\ \log_a(bc)=\log_a(b) + \log_a(c)\\\end{array}}\)
By using the log product law, we can express log₇(xz) as:
\(\log_7(xz) =\log_7(x) + \log_7(z)\)
\(\hrulefill\)
Part (b)\(\boxed{\begin{array}{c}\underline{\textsf{Quotient law}}\\\\\log_a \left(\dfrac{b}{c}\right)=\log_a(b) - \log_a(c)\end{array}}\)
By using the log quotient law, we can express log₇(y/x) as:
\(\log_7 \left(\dfrac{y}{x}\right)=\log_7(y) - \log_7(x)\)
\(\hrulefill\)
Part (c)\(\boxed{\begin{array}{c}\underline{\textsf{Power law}}\\\\\log_ax^n=n\log_ax\end{array}}\)
By using the log power law, we can express log₇(∛z) as:
\(\begin{aligned}\log_7 \left(\sqrt[3]{z}\right)&=\log_7 \left(z^{\frac{1}{3}\right) \\&=\dfrac{1}{3}\log_7(z)\end{aligned}\)

b) The car travels 4 miles every minute.
c) The car travels 4 miles every 5 minutes.
d) The car travels 5 miles every 4 minutes.
125
80
100
Given statement solution is :- None of the given options (a, b, c, or d) match the meaning of the slope. The correct interpretation is that the car travels approximately 0.8 miles every minute.
To determine the meaning of the slope of the linear model for the given data, let's analyze the information provided. The table represents the distance traveled by a car at different time intervals.
Minutes | Distance Traveled (in miles)
50 | 20
20 | f
40 | 60
100 | a
125 | 80
100 | 100
To find the slope of the linear model, we need to calculate the change in distance divided by the change in time. Let's consider the intervals where the time changes by a fixed amount:
Between 50 minutes and 20 minutes: The distance changes from 20 miles to 'f' miles. We don't have the exact value of 'f', so we can't calculate the slope for this interval.
Between 20 minutes and 40 minutes: The distance changes from 'f' miles to 60 miles. Again, without knowing the value of 'f', we can't calculate the slope for this interval.
Between 40 minutes and 100 minutes: The distance changes from 60 miles to 'a' miles. We don't have the exact value of 'a', so we can't calculate the slope for this interval.
Between 100 minutes and 125 minutes: The distance changes from 'a' miles to 80 miles. Since we still don't have the exact value of 'a', we can't calculate the slope for this interval.
Between 125 minutes and 100 minutes: The distance changes from 80 miles to 100 miles. The time interval is 25 minutes, and the distance change is 100 - 80 = 20 miles.
Therefore, based on the given data, we can conclude that the car travels 20 miles in 25 minutes. To determine the meaning of the slope, we divide the distance change by the time change:
Slope = Distance Change / Time Change
= 20 miles / 25 minutes
= 0.8 miles per minute
So, none of the given options (a, b, c, or d) match the meaning of the slope. The correct interpretation is that the car travels approximately 0.8 miles every minute.

Step-by-step explanation:
On edge
The probabilities is the greatest for a standard normal distribution is
P(-0.5 ≤ z ≤ 0.5) = 0.382.
What is Normal Distribution?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically towards either extreme. The distribution's mean is another name for the centre of the range.
From the diagram attached below, we can write
1. P( -1.55 ≤ z ≤ -0.5)
= 0.092 + 0.15
= 0.242
or, 9.2%+15%=24.2%.
2. P( -0.5 ≤ z ≤ 0.5)
= 0.191 + 0.191
= 0.382
3. P( 0.5 ≤ z ≤ 1.5)
= 0.15 + 0.092
= 0.242
4. P( 1.5 ≤ z ≤ 2.5)
= 0.044 + 0.017
= 0.061
So, the greatest value is P(-0.5 ≤ z ≤ 0.5) = 0.382

On the graph, we can see a system of linear equations, we can see a line with a positive slope and a line with a negative slope.
The line with a positive slope intercepts the y-axis at y = -6, then that line is:
y = a*x - 6
with a > 0.
The other line passes through the y-axis at y = -2, then the linear equation is:
y = b*x - 2
Where b < 0.
Also, remember that the solution for the system of equations is the point where the two lines intersect, so we can see that the solution is at (2, -4)

consider the initial value problem find the value of the constant and the exponent so that is the solution of this initial value problem.
The value of the constant, c is 4 and the value of the exponent, r is 2.
To find the solution to this initial value problem, we need to solve for c and r.
First, we can divide both sides of the equation by 2t:
y′ = 2y/t
Next, we can separate the variables:
dy/y = 2dt/t
Integrating both sides, we get:
ln|y| = 2ln|t| + C
Exponentiating both sides:
|y| = Ce^(2ln|t|) = \(C(|t|^2)\)
Since y can be negative or positive, we can write:
y = ±C\(|t|^2\)
To find the value of C, we can use the initial condition y(2) = −8:
−8 = ±C(\(2^2\))
Solving for C, we get:
C = −4
The following is the answer to the starting value problem:
y = −\(4|t|^2\)
Note that \(|t|^2\) = \(t^2\) for positive t and \(|t|^2\) = -\(t^2\) for negative t, so we can write:
y = -4\(t^2\) for t > 0
y = 4\(t^2\) for t < 0
So the value of c is 4 and the value of r is 2.
The complete question is:-
Consider the initial value problem 2ty′=4y, y(2)=−8. 2ty′=4y, y(2)=−8. find the value of the constant c and the exponent r so that y=ctry=ctr is the solution to this initial value problem.
