Answer:
The equation that passes through (−7,−3)and (−2,−1) is y=2/5x-1/5
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-1)-(-3)/(-2)-(-7)
m=2/5
y-y=m(x-x¹)
y-(-1)=2/5(x-(-2)
y+1=2/5x+4/5
-1 -1
y=2/5x-1/5
Marcus was showing how he solved a division problem with the area model below. His pen exploded ink on some of his work.
What is the divisor that is covered with ink on the left side of the model?
A. 100
B. 80
C. 56
D. 29
Answer:
C
Step-by-step explanation:
80 is what percent 300 ( please explain)
(80×100):300=
8000:300=26.67
so 80 percent of 300 is 26.67

Find a 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms. The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms is:____.
Answer:
hello your question is incomplete attached below is the complete question
answer : ( 184.019 , 206.219 )
Step-by-step explanation:
The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms can be calculated using this relationship below
y = Bo + B1 ( 200 ) = 195.118621 , sy =
hence a 95% confidence interval = 195.118621 ± 2.306( 4.813492) i.e. ( 184.019 , 206.219 )
attached below is the remaining part the solution
A plane set off to Portland at a speed of 232 mph. On the
return flight of 12 hours, the plane cruised at 204 mph.
How many hours long was the flight to Portland?
Answer:
The flight to Portland takes 10.6 hours.
Step-by-step explanation:
To find the time of flight to Portland we need to calculate the distance traveled by using the equation:
[tex] x = v*t [/tex]
Where:
v: is the speed = 204 mph (return flight)
t: is the time = 12 h (return flight)
[tex] x = v*t = 204 mi/h*12 h = 2448 mi [/tex]
Now, we can find the time of flight to Portland using v = 232 mph:
[tex]t = \frac{x}{v} = \frac{2448 mi}{232 mi/h} = 10.6 h[/tex]
Therefore, the flight to Portland takes 10.6 hours.
I hope it helps you!

What's the solution to -182=2(1+2x)-2
Answer: [tex]x = -\frac{91}{2}[/tex]
Step-by-step explanation:
If you have any questions, feel free to ask :)
Step 1: Add [tex]2[/tex] to both sides.
[tex]-182 + 2 = 2(1 + 2x)[/tex]
Step 2: Simplify [tex]-182 + 2[/tex] to [tex]-180[/tex].
[tex]-180 = 2(1 + 2x)[/tex]
Step 3: Divide both sides by [tex]2[/tex].
[tex]-\frac{180}{2} = 1 + 2x[/tex]
Step 4: Simplify [tex]\frac{180}{2}[/tex] to [tex]90[/tex].
[tex]-90 = 1 + 2x[/tex]
Step 5: Subtract [tex]1[/tex] from both sides.
[tex]-90 - 1 = 2x[/tex]
Step 6: Simplify [tex]-90 - 1[/tex] to [tex]-91[/tex].
[tex]-91 = 2x[/tex]
Step 7: Divide both sides by [tex]2[/tex].
[tex]-\frac{91}{2} = x[/tex]
Step 8: Switch sides.
[tex]x = -\frac{91}{2}[/tex]

How far up a wall will a 13-meter ladder reach, if the foot of the ladder is 6 meters away from the base of the wall?
A. 12 m
B. 4 m
C. 133 m
D. 245 m
Answer: C
Step-by-step explanation: I took the test!!
The required distance that the ladder foot away from the base of the wall is √133 meters. Option C is correct.
What are Pythagorean triplets?In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.
Here,
Let the base length be x,
According to the question, a 13-meter ladder reach, the foot of the ladder is 6 meters.
So, applying the Pythagoras theorem,
13² = 6² + x²
x = √169 - 36
x = √133
Thus, the required distance that the ladder foot away from the base of the wall is √133 meters.

If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth of the county's population, estimate the population of the county in 2023. (P0 is the initial population. Round your value of h to four decimal places. Round your answer to the nearest whole number.)
Answer:
126807 people
Step-by-step explanation:
Given;
P= Poe^ht
Where;
P= population at time t
Po= population at the beginning
h= growth constant
t= time
1998- 2008 is ten years.
110429= 100,000e^10h
1.1 = e^10h
ln(1.1) = lne^10h
0.095 = 10h
h= 0.0095
In 2023, t = 25 years
P= 100,000e^(0.0095 × 25)
P= 126807 people

We can calculate the decimal by converting the fraction to an improper fraction, then dividing.
Derive the inpromper fraction by:
[tex]a\frac{b}{c} = \frac{c * a + b}{c}[/tex]
In this instance:
[tex]-8\frac{2}{5} = \frac{-8* 5 -2 }{5} = \frac{-42}{5}[/tex]
