Answer:
Calculating two points and drawing the line between the two.
Explanation:
To find the y-intercept, put x = 0
y = 2 (0) - 1
y = -1
To find the x-intercept, put y = 0
2x - 1 = 0
2x = 1
x = 1/2
Draw your system of axis. Mark -1 on the y-axis, and 1/2 on the x-axis.
Now draw a line through these two ponts. Add arrows.
==============================================
To draw the graph by using points,
let x = -1, then y = 2 (-1) - 1 = -2 - 1 = -3
first point is (-1; -3)
Let x = 0, y = 2 (0) - 1 = -1
Second point is (0; -1)
Let x = 1, y = 2(1) - 1 = 1
Third point is (1; 1)
Plot the three points and draw a line through them. Add arrows to your line.

Simone read online that the failure rate in Arizona for the first attempt of the written driver’s test is 60%. Simone thinks the Arizona rate is less than 60%. To investigate, she selects an SRS of 50 Arizona drivers and finds that 27 failed their first written driving test. To determine if this provides convincing evidence that the failure rate for Arizona is less than 60%, 200 trials of a simulation are conducted. Simone’s hypotheses are: H0: p = 60% and Ha: p < 60%, where p = the true proportion of Arizona drivers who fail the first attempt of the written driver’s test. Based on the results of the simulation, the estimated P-value of this test is 0.035. Using ∝ = 0.05, what conclusion should Simone reach?
Answer:
The answer is "Choice d".
Step-by-step explanation:
Please find the complete question in the attached file.
Although Simone read today, a first written driver test rate of failure is 60 percent to Arizona.
Range of population = p = 0.60 . Simone assumes the Arizona average would be below 60%. She selects an SRS of 50, but she discovers 27 have failed their first published driver's test (sample size n= 50).
Now 200 simulated experiments were conducted to determine when that offers compelling proof which Arizona has a failure rate of less than 60%. The hypothesis of Simone is p = 60% and p < 60% where p = true share of Arizona pilots who fail the very first test of a written pilot.
The evaluated P-value of this experiment is 0.035 based on the results of the simulation. α = 0.01
Whereas if p-value < α = degree of significance, we reject the null hypothesis. p-value [tex]= 0.035 > 0.01[/tex]

Find the length DE. Round your answer to the nearest tenth of a meter
Answer:
13.8
Step-by-step explanation:
We can use trigonometry to find the length of DE
Remember these are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
For ∠FDE we are given its opposite side length ( FE ) and need to find its adjacent angle ( DE )
When working with opposite and adjacent we use the trig ratio tangent
That being said we want to create an equation to solve for (DE) ( Recall that tan = opposite over adjacent. ) ( let DE = x )
so [tex]tan(51)=\frac{17}{x}[/tex]
now we solve for x
Step 1 multiply each side by x
tan(51) * x = x tan (51)
[tex]\frac{17}{x} *x=17[/tex]
now we have x tan (51) = 17
step 2 divide each side by tan (51)
[tex]\frac{xtan(51)}{tan(51)}=x\\\frac{17}{tan(51)}[/tex]
we now have
[tex]x =\frac{17}{tan(51)} \\[/tex]
[tex]tan(51)=1.234897157\\\frac{17}{1.234897157} =13.76632856[/tex]
we're left with x = 13.76632856
Finally we round to the nearest tenth and get that the answer 13.8
a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance it covers? i'll give brainliest to whoever answers first/correctly!
we know that
1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long
applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall
a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft
the answer is
5.92 ft
Answer:
6.08 or so
Step-by-step explanation:
The height is 1 foot, while the length is 6 feet.
You can use the Pythagorean Theorum to solve this, as you plug in the values.
The theorum states that A squared plus B squared = C squared, where A is the length, and B is the width. (It doesn't matter if A is the width and B is the length either.)
So if we plug in the values:
1 squared plus 6 squared = C squared.
1 + 36 = 37
Since it is C squared, we can find the square root of 37, which is something like 6.0827625302982196889996842452021.
So usually we round to the hundredths place, so we can use 6.08.

The equation for the speed/distance of a tornado is
s = 93 log(d) + 65.
If the speed is 310 mph, what is the distance?
Answer:
430.93 miles (rounding to the nearest hundredth)
Step-by-step explanation:
s = 93 log(d) + 65
310 = 93 log(d) + 65
245 = 93 log(d)
2.634408602 = log(d)
10^2.634408602 = 10^log(d)
430.9318583 = d
Therefore, if the speed of the tornado is 310 mph, then its distance is about 430.93 miles.

Solve the following system of equations for x
2x-y=4
y-x=4
Answer:
What do i do???
Step-by-step explanation:
Answer:
x = 8
y = 12
Step-by-step explanation:
Given equations are -
2x - y = 4 .......(1)
-x + y = 4 ........(2)
Add both equations, we get
2x - y + (-x + y) = 4 + 4
⇒2x - y - x + y = 8
⇒x = 8
Now,
Put the value of x in equation (2), we get
y - 8 = 4
⇒y = 4 + 8
⇒y = 12
∴ we get
x = 8
y = 12

Only 1 is needed, but doing both would be godly <33
Answer:
1. y = 4x - 27
2. y = -4x - 15
Step-by-step explanation:
If two lines are parallel, then they have the same slope. So, the slope of the line we are looking for needs to be 4. We can start by writing a point-slope equation:
y - y1 = m(x - x1)
We can substitute the values we have, the point we are using is (8, 5) because it needs to be on the line:
y - 5 = 4(x - 8)
We can distribute:
y - 5 = 4x - 32
y = 4x - 27
We are not given the slope-intercept form, so we must divide both sides by two to get it:
y = 1/4 x + 8
A perpendicular line has the slope that is the negative reciprocal of the one that is given. So, the slope of the line would be - 4. We can start by writing a point-slope equation:
y - y1 = m(x - x1)
We can substitute the values we have, the point we are using is (-5, 5) because it needs to be on the line:
y - 5 = -4(x + 5)
We can distribute:
y - 5 = -4x - 20
y = -4x - 15

How do u find the area of a square? And other shapes??! Please help failing classes!
Answer:
you find the area of a square by multiplying the side length by the side length. For example, the side length of a square is 10, then the area of the square would be 10 * 10= 100, the area would have been 100. A=l*l
I dont know what other shapes do you need so i would tell you how to find the area of a triangle. you find it by multiplying the base and the height and times it by 1/2. A=1/2*b*h
Answer:
Finding Area Of Shapes
Step-by-step explanation:
The formula for solving for area of a square is A= S x S which basically means Area = Side multiplied by side, S is the length of each side of the square. With squares, it's much easier to find the length because it's all going to be the same on each side so you multiply the number by its self to get your answer.
Example :
8 x 8 = 64
So the area of the square would be 64 if each side were 8 because you're going to multiply using 2 sides and multiply that number by itself.
Hope this helps let me know if you need any other help!

A square is split into four
similar squares, one of
the new squares is split
into fourths again, and
this process continues.
What kind of sequence
does this demonstrate?
Answer:
Geometric Sequence.
Step-by-step explanation:
We are told that the square is split into 4 similar squares. One of the new squares is now split into fourths again and this same sequence is repeated over again.
This means that there is a common ratio which is ¼.
Since there is a common ratio and not common difference, this sequence is said to be a geometric sequence.
