What is the slope of the line that runs through points (-1,-7) and (2,5)? Write the equation of that line.
Write slope intercept form general for the equation
y = mx + b
in this equation m = Y/X.
Y = y - y'
X = x - x'
then find m
m= (-7 -5)/ (-1 -2) = -12/-3 = 4
then equation becomes
y = 4x + b
b = y - 4x . Replace (x,y) = ( -1,-7)
b= -7 -4•(-1) = -3
Then finally eqaution of that line is
y = 4x -3
What should you substitute for x in the second equation (bottom equation) in order to solve the system by the substitution method?
We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.
The given system of equations are 2x-1/3y = -2...(1)
3x+y=1...(2)
We solve this system of equations by using substitution method.
Let us solve for x in equation to substitute it in equation (2).
2x=-2+1/3y
Divide both sides of equation by 2.
x=-1+1/6y
Now plug in the value of x in equation 2.

Find the critical value
χ2R
corresponding to a sample size of 5 and a confidence level of 99.0 percent
The critical value, given the sample size of 5 and the confidence level of 99. 0 percent would be 16. 812.
How to find the critical value ?The critical values for the chi-squared (χ^2) distribution depend on the degree of freedom and the level of significance.
The degree of freedom for a chi-squared distribution typically equals the sample size minus 1 so the degrees of freedom here is:
= 5 - 1
= 4
The level of significance would be:
= 1 - 99. 0 %
= 0. 01
The critical value of the sample would therefore be found on a chi -squared distribution table for df = 4 and α = 0.01 to be 16. 812.

The Bureau of Transportation Statistics data for domestic flights from January 2006 to December 2012 was retrieved for the analysis. The quantitative analysis also focused on finding critical statistical values like mean, median, mode, standard deviation, variance, and minimum/maximum variables. The results of the data are summarized in Table 2. Revenue Passenger Miles (RPM) mean is 6,624,897, the median is 6,522,230, and mode is NONE. The minimum is 5,208,159 and the maximum is 8,277,155. The standard deviation is 720,158.571, and the variance is 518,628,367,282.42.
Load Factors (LF) mean is 82.934, the median is 83.355, and mode is 84.56. The minimum is 74.91, and the maximum is 89.94. The standard deviation is 3.972, and the variance is 15.762. The Available Seat Miles (ASM) mean is 7,984,735, the median is 7,753,372, and mode is NONE. The minimum is 6,734,620, and the maximum is 9,424,489. The standard deviation is 744,469.8849, and the variance is 554,235,409,510.06.Figure 1 above displays the performance of American Airlines (Domestic).
The mean RPM is 7,984,735, and the linear regression line is y = 50584x - 2.53E+8. The linear regression line indicates a positive relationship between RPM and year, with a coefficient of determination, R² = 0.6806. A coefficient of determination indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. Therefore, 68.06% of the variance in RPM is predictable from the year. A one-way ANOVA analysis of variance test was conducted to determine the equality of means of three groups of variables; RPM, ASM, and LF. The null hypothesis is that the means of RPM, ASM, and LF are equal.
The alternative hypothesis is that the means of RPM, ASM, and LF are not equal. The level of significance is 0.05. The ANOVA results indicate that there is a significant difference in means of RPM, ASM, and LF (F = 17335.276, p < 0.05). Furthermore, a post-hoc Tukey's test was conducted to determine which variable means differ significantly. The test indicates that RPM, ASM, and LF means differ significantly.
The skewness test was conducted to determine the symmetry of the distribution of RPM, ASM, and LF. The test indicates that the distribution of RPM, ASM, and LF is not symmetrical (Skewness > 0).
Additionally, the z-statistic test was conducted to determine the deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

A $5000 principal is invested in two accounts, one earning 1% interest and the another earning 6% interest. If the total interest for the year is $170, then how much is invested in each account?
Answer: in the 1% account we have $2600 and in the 6% account we have $2400.
Step-by-step explanation:
We have two amounts A and B such that:
Where A is the amount invested in the 1% earning interest account and B is the amount invested in the 6% earning interest account.
A + B = $5000,
If the interest is yearly, then we have that, after one year, the interest is:
A*(1%/100%) + B*(6%/100%) = $170
A*0.01 + B*0.06 = $170
So we have two equations:
A + B = $5000
A*0.01 + B*0.06 = $170
In the first equation we can isolate A and get:
A = $5000 - B
and replace it in the other equation:
($5000 - B)*0.01 + B*0.06 = $170
$50 + B*0.05 = $170
B*0.05 = $120
B = $120/0.05 = $2400
Then A = $5000 - $2400 = $2600.

What is the range of the exponential function shown below?
f(x)=11•(1/3)^x
A. y<0
B. y>0
C. All real numbers except 11
D. All real numbers
The range of the exponential function is B. y > 0.
The range of the exponential function f(x) = 11 × (1/3)ˣ can be determined by analyzing the behavior of the function as x approaches positive and negative infinity.
As x approaches positive infinity, (1/3) becomes smaller and smaller, tending towards zero.
f(x) approaches 11 × 0, which is equal to 0.
As a result, the function approaches 0 as x goes to infinity.
On the other hand, as x approaches negative infinity, (1/3)ˣ becomes larger and larger.
Since 1/3 is between 0 and 1, raising it to a negative power causes it to grow exponentially.
f(x) approaches infinity as x goes to negative infinity.
Combining these two behaviors, we can conclude that the range of the function f(x) = 11 × (1/3)ˣ is all positive real numbers, excluding zero.
In other words, the range is y > 0.

Mary reduced the size of a painting to a
width of 5.4 in. What is the new height if it
was originally 46.5 in height and 32.7 in width?
Round to nearest tenth of an inch.
By finding the scale factor as a quotient of the two given widths, we will see that the new height is 7.7 in
How to get the new height?
We assume that the height and the width are reduced by the same scale factor.
Such that the scale factor is given by the quotient between the new width and the original width, so we have:
k = 5.4in/32.7in = 0.1651
Then the new height will be the original height times the above number, which gives:
H = 0.1651*46.5 in = 7.7 in
We conclude that the new height of the painting is 7.7 inches.
