Answer:
y-intercept → (-5)
Slope → 4
Equation → y = 4x - 5
Step-by-step explanation:
From the table attached,
y - intercept → Output value at x = 0
y = -5
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{-13-(-9)}{-2-(-1)}[/tex]
= [tex]\frac{-13+9}{-2+1}[/tex]
= [tex]\frac{-4}{-1}[/tex]
= 4
m = 4
Equation of a line is given by,
y = mx + b
Here, m = Slope
b = y-intercept
Therefore, equation of the line will be,
y = 4x + (-5)
y = 4x - 5

Answers
Answer:
1 4/25 - 3/5, or 29/25 - 3/5, or [tex]\frac{(29m - 15)}{25}[/tex]
it doesn't really matter they all mean the same
Step-by-step explanation:
1 2/5m - 3/5(2/5m + 1)
multiply first
1 2/5m - 6/25m - 3/5
multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

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]
Divide:
-42 ÷ 5 = -8.4.

An airport is studying the noise levels of jets during takeoff as they pass over a neighborhood. They find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels. The distribution of noise levels for all jets during takeoff over the neighborhood has a normal distribution. What percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood
Answers
Answer: 2.28%
Step-by-step explanation:
Given: An airport find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels.
The distribution of noise levels(x) for all jets during takeoff over the neighborhood has a normal distribution.
The probability that jets have a noise level less than 92.2 decibels when taking off over this neighborhood will be :-
[tex]P(X<92.2)=P(\dfrac{X-\mu}{\sigma}}<\dfrac{92.2-103}{5.4})\\\\=P(Z<-2)\\\\=1-P(Z<2)\\\\=1- 0.9772498\ \ \ [\text{By p-value table}]\\\\=0.0227502\approx2.28\%[/tex]
Hence, the percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood = 2.28%

A. 12 m
B. 4 m
C. 133 m
D. 245 m
Answers
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.

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?
Answers
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.

Using confidence interval concepts, it is found that the margin of error is 5.
What is a confidence interval?A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval has the format (a,b).
The margin of error is half the difference between the two bounds, that is:
M = ( b - a ) / 2
In this problem, the interval is (32, 42), hence, and the margin of error is:
M = ( 42 - 32 ) / 2 = 10 / 2 = 5
Therefore the margin of error is 5.
