First let's reduce the feet to miles
there are 5280 feet in a mile therefore
26400 feet=5 miles
31680 feet=6 miles
Jet A(the first jet) descends 5 miles in 96 miles
Jet B(the second jet) descends 6 miles in 120 miles
We can compare these as fractions to see which is steeper. This can be viewed as slope and the origin (0,0) is the airport.
slope: 6/120=?=5/96
1/20=?=5/96
Now we know that 5/100 =1/20 so 5/96 must be bigger than 5/100 because you are dividing by a smaller number.
so 1/20<5/96
So Jet B is descending steeper than Jet A.
As for linear model, I don't exactly know what your teacher means but I think I actually used the linear model when I'm thinking of steepness as slope in the coordinate plane, I will include a picture.
In this extremely zoomed out graph, you can see the blue line is just slighly higher than the red line(slope as in explanation is way easier to tell) this could be seen as the linear model) :) Hope it helped!

In the past, 30% of a country club's members brought guests to play golf sometime during the year. Last year, the club initiated a new program designed to encourage members to bring more guests to play golf. In a sample of 95 members, 34 brought guests to play golf after the program was initiated. When testing the hypothesis that the new program has increased the proportion of members bringing out guests (using a 5% level of significance), what is the null and alternative hypothesis
Answers
Answer:
The null hypothesis, H₀: p = 0.3
The alternative hypothesis is Hₐ: p ≠ 0.3
Step-by-step explanation:
The null hypothesis, H₀, in inferential statistics is the default hypothesis that the measured quantity is zero or null and therefore there is no difference between the population characteristic measured, when the quantity measured is the difference between two situations
Therefore, the null hypothesis, H₀: p = 0.3
The alternative hypothesis is usually the opposite of the null hypothesis, therefore, the alternative hypothesis Hₐ is given as follows;
The alternative hypothesis is Hₐ: p ≠ 0.3
What's the probability of the compound event for. A bag contains 4 red, 8 blue, 6 yellow and 2 green marbles. Maria selects a marble, puts it back and then selects a second marble. P (blue, red)
Answers
Given:
Number of red marbles = 4
Number of blue marbles = 8
Number of yellow marbles = 6
Number of green marbles = 2
To find:
The probability of getting a blue marble then a red marble, i.e., P(blue, red).
Solution:
Using the given information,
The total number of marbles = 4+8+6+2
= 20
Probability of getting a blue marble in first draw is
[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(Blue)=\dfrac{8}{20}[/tex]
[tex]P(Blue)=\dfrac{2}{5}[/tex]
Maria selects a marble, puts it back and then selects a second marble. It means the total number of marbles remains the same.
[tex]P(red)=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(red)=\dfrac{4}{20}[/tex]
[tex]P(red)=\dfrac{1}{5}[/tex]
Now, the probability of getting a blue marble then a red marble is
[tex]P(blue,red)=\dfrac{2}{5}\times \dfrac{1}{5}[/tex]
[tex]P(blue,red)=\dfrac{2}{25}[/tex]
Therefore, the required probability P(blue, red) is [tex]\dfrac{2}{25}[/tex].

Answer:
y= 10x + 4
Step-by-step explanation:
-10x + y = 4
-10x + y +10x = 10x + 4
y= 10x + 4
depending on what its asking usually this is what its asking for but im not sure exaclty what its asking so here.....
next step is to plug the numbers in
so for the first box it says that x is -2
plug it in.....
y = 10(-2) + 4
y = -20 + 4
y = -16
then keep doing it for the next boxes.....
second box:
y = 10(-1) + 4
y = -10 + 4
y = -6
third box:
y = 10(0) + 4
y= 4 because 10 times zero is zero (basically any number times 0 is zero)
fourth box:
y = 10(1) + 4
y = 10 + 4
y = 14
fifth box:
y = 10(2) + 4
y = 20 + 4
y = 24

Use substitution to solve the following system of equations. 4x – 13y = -12 AND X = 2y - 8
Answers
Answer:
y=5/4=0.8
Step-by-step explanation:
(4×2y−8)−13y=−12
Multiply 4 and 2 to get 8.
8y−8−13y=−12
Combine 8y and −13y to get −5y.
−5y−8=−12
Add 8 to both sides.
−5y=−12+8
Add −12 and 8 to get −4.
−5y=−4
Divide both sides by −5.
y=−5−4
Fraction −5/−4 can be simplified to 5/4 by removing the negative sign from both the numerator and the denominator.

PLEASE HELP!! The AHS Football team did a weigh in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. Which of the following curves represents the data? A,B, Or C??
Answers
Answer: Choice C
=========================================================
Explanation:
The mean is 98, so that's the center of the distribution. This is where the highest point occurs because the most people are clustered around here. This rules out choice A and the answer is between B or C.
One standard deviation above the mean is 98+6 = 104. All we do is add on the standard deviation (6) to the mean (98) to get 104.
One standard deviation below the mean is 98-6 = 92
The graph that has tickmarks at 92 and 104 indicate we are exactly 1 standard deviation from the mean (98)
Similarly, 2 standard deviations above the mean is at 98+2*6 = 98+12 = 110. Or you could say 104+6 = 110.
2 standard deviations below the mean would get us to 98-2*6 = 98-12 = 86
The same idea applies to 3 standard deviations as well.
All of this matches with graph C. We can eliminate graph B by noticing that something like 95 is not a result of 98-6.
The value of a is the value of B is the value of C is

Find the equation of the line with slope m=1 that contains the point (1,2)
Answers
Answer:
y = x + 1
Step-by-step explanation:
We can use the point-slope formula to write an equation for this problem. The point-slope formula states: (y - y1) = m (x - x1)
Where m is the slope and (x1 y1) is a point the line passes through.
Substituting the slope and the values from the point in the problem gives:
( y - 2 ) = 1 ( x - 1 )
We can also solve for y to put the equation in slope-intercept form. The slope-intercept form of a linear equation is: y = mx + b
y - 2 = 1x - 1
y = 1x - 1 + 2
y = 1x + 1 or y = x + 1 * are just the same.
The equation of the line is y = x + 1.
What is a slope?The slope and direction of a line are represented numerically by the line's gradient, which is also referred to as the slope in mathematics.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
And here we have the slope,
m = 1
And (x₁ ,y₁) = (1,2)
then the equation of line is
y - y₁ = m (x - x₁)
y - 2 = (x -1)
y = x + 1
Therefore, the equation is y = x + 1.
