Actually Welcome to the Concept of the Straight lines.
Since there are more than one lines that can land plane safely, we take one of it,
When, X = 10 and Y = 7, so the equation we get as,
y-7 = m(x-10) + c
lets find slope, that is value of m,
y2-y1/x2-x1 = m
so, 9-7/ 7-10 = 2/-3
so, m= -2/3
so the final Equation is,
=> y-7 =(-2/3)(x-10) +c
Isabella pitches for her high school softball team. Of the 7 pitches she throws, 5 are strikes. She uses a standard deck of cards to model her pitches, with hearts, clubs, and spades representing strikes. Which statement about her model is true?
A- Her model can be improved the most by removing all the face cards from the deck. B-Her model cannot be improved. C-Her model can be improved the most by removing all the aces from the deck. D-Her model can be improved the most by removing the queens and kings of hearts, clubs, and spades.
Answer:
B. Her model cannot be improved.
Step-by-step explanation:
We make this conclusion because it seems Isabella's model isn't actually proffering any solution to increase/reduce the number of strikes she has had.
Hence, any changes made do not clearly seem to improve the present model she is using.

Step-by-step explanation:
Exits along interstate highways were formerly numbered successively from the western or southern edge of a state. However, the department of transportation has recently changed most of them to agree with the numbers on the mile markers along the highway. (a) what level of measurement were data on the consecutive exit numbers? Nominal ratio interval ordinal (b) what level of measurement are data on the milepost numbers? Nominal ordinal ratio interval (c) the newer system provided information on the distance between exits.
a. True
b. False
Answer:
Following are the answer to this question:
In question, a) ordinal.
In question, b) ratio .
In question, c) true.
Step-by-step explanation:
For its "ordained" existence, regular data is used to conduct surveys and questionnaires. To identify respondents into different categories, a quantitative methodology is employed to sufficient excess.
Its ratio data is defined as a statistical method with the same features as continuous variables, that recognize the proportion of each data to an absolute null as its source. In many other words, the meaning of the line graph may not be positive.
Its newest program gives the gap between exits data.
A car wheel has a diameter of 20.8 inches.
About how far does the car wheel travel in 1 rotation? 5 rotation? 30 rotations?
Answer:
65.312 inches326.56 inches1959.36 inchesStep-by-step explanation:
Givend = 20.8 inchesTo findTravel in 1, 5, 30 rotationsSolutionCircumference of the wheel is equal to one full rotation
C = πd = 3.14*20.8 = 65.312 inches5C = 5*65.312 = 326.56 inches30C = 30*65.312 = 1959.36 inchesAnswer:
1 rotation: 65.312 inches
5 rotations: 326.56 inches
30 rotations: 1959.36 inches
Circumference = π and diameter
3.14 x 20.8 = 65.312 inches
5C = 5 x 65.312 = 326.56 inches
30C = 30 x 65.312 = 1959.36 inches

I'm more than 9 dozen and less than the number of days in 4 months. The sum of my digits is 11.
Answer: 92 or 119
in 4 months, 2 months with 30 days per month, 2 months with 31 days per month
suppose: the number to find is X
have: 90 < X < 30.2 + 31. 2 ⇔ 90 < X < 122
if X is a number has 2 digits => X is xy
=> [tex]\left \{ {{x+y=11} \atop {90<x\leq 100}} \right.[/tex]
=> xy = 92
if X is a number has 3 digits => X is abc
we have: [tex]\left \{ {{a+b+c=11} \atop {100\leq abc<122}} \right.[/tex]
because 100 ≤ abc < 122 => a = 1; b = 0 or 1
+) if a =1 ,b = 0 but a+ b +c = 11 => c = 10 (removed because c is a 1-digit number)
+) if a = 1, b = 1 => c = 9
=> abc = 119
=> X is 92 or 119

Answer:
The mean proportional of 6, and 24 will be 12
Step-by-step explanation:
We know that the Mean proportional of two

Therefore, the mean proportional of 6, and 24
[tex]=\sqrt{6\times 24}[/tex]
[tex]=\sqrt{144}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:144=12^2[/tex]

mitosis also occures when cells are worn out or are injured and the mitosis will replace the injured cells
Explain what is occurring in each chunk of the graph
Answer:
Please check the explanation.
Step-by-step explanation:
As the given graph includes distance 'd' at the y-axis and time 't' at the x-axis.
so from the distance-time graph, it is clear that the graph includes 5 chunks.
The first chunk of the graph indicates that the object has started traveling. And the distance 'd' is being covered in time 't', as the slope is upward, hence the speed of the object is increasing.
Please note that speed is basically the distance covered per unit time.The second chunk of the graph indicates the no distance is being covered. It means the object is at rest.
The third chunk of the graph indicates that the distance 'd' is being covered in time 't', as the slope is again upward, hence the speed of the object is increasing and the object has started traveling.
The fourth chunk of the graph indicates that the slope is downward, and the object has started traveling to get back to the destination, and eventually, the object has reached the starting point.

- Mt. Everest is considered the tallest mountain in the world at 8,848 meters above sea level. In fact, the forgest
mountain in the world is Mauna Loa, in Hawai'i, Mauna Loa rises 4, 170 meters from sea level to the top of the
summit, but its base is deep under water. The base of the mountain is at -5,000 meters,
A probe is dropped 7, 500 meters straight down into Mauna Los from its summit.
At what height is the probe, relative to sea level?
meters
How far is the probe from the base of the volcano?
meters
Answer: 10000
A.) 4170m above sea level ;3330m below sea level
B) 1670 m from the base.
Step-by-step explanation:.
Given that:
Mauna Loa :
4,170 meters (from sea level to summit)
-5000 meters (base of mountain to sea level)
Depth of probe dropped from summit of Mauna Loa = 7500 m
Height of probe relative to sea level :
Depth of probe - height of Mauna Loa(from sea level to summit)
7500 m - 4170 m = 3330 m
Hence, height of probe relative to sea level :
4170m above sea level
3330m below sea level
Distance of probe from base of volcano:
Total depth of Mauna Loa = (4170 + 5000) = 9170m
Total depth of probe = 7500 m
Distance of probe from base :
9170 - 7500 = 1670 m
The probe is 1670 m from the base of the volcano.

Write an equation of the line graphed in slope-intercept form:
Answer:
-2.5x+2
I hope this is good enough:
y-intercept is at positive 2 so you would have +2
it has a negative slope because it is going downwards
on the graphing calculator I used 2 wasn't big enough to make the x intercept and 3 was to big so I went in the middle and it looked correct.
