According to a study conducted by an organization, the proportion of americans who were afraid to fly in 2006 was 0. 10. A random sample of americans results in indicating that they are afraid to fly. Explain why this is not necessarily evidence that the proportion of americans who are afraid to fly has.
According to the the concept of hypothesis testing, there is no evidence that the proportion of Americans who are afraid to fly has decreased.
Hypothesis testing:
Basically, in math hypothesis, it test the population on the basis of the sample data taken from the population using a simple random sampling.
Given,
According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0. 10. A random sample of 1300 Americans results in 117 indicating that they are afraid to fly.
Now, we need to explain why this is not necessarily evidence that the proportion of Americans who are afraid to fly has.
While we looking into the given question,
Sample size, n = 1300
Number of Americans who were afraid to fly, x = 117
Now, we have to computing the sample proportion of Americans who afraid to fly,
Therefore, p = 117 / 1300 = 0.09
Then the Formulation of Hypotheses is written as,
Here the Null Hypothesis: H0: p≥0.10
And the alternative Hypothesis: Ha: p<0.10
Then the Left-tailed test of Test statistic is written as,
Here Let us assume that the level of significance, α = 0.05.
Then the Critical value, z≈−1.645
And the Decision rule is written as
If the value of |z|<|z0.05|≈1.645: Do not reject the null hypothesis.
Otherwise If value of |z|≥|z0.05|≈1.645: Reject the null hypothesis.

Sal has already finished startfraction 5 over 9 endfraction of the 45 math problems he was assigned. If each math problem took him three-fifths of a minute to finish and this pace continues, which expression can be used to determine the amount of time it will take him to finish his remaining homework? 45 times startfraction 5 over 9 endfraction times three-fifths 45 times startfraction 5 over 9 endfraction divided by three-fifths 45 times startfraction 4 over 9 endfraction times three-fifths 45 times startfraction 4 over 9 endfraction divided by three-fifths.
The correct expression to determine the amount of time is 45 times startfraction 4 over 9 endfraction times three-fifths.
Sal has finished = 5/9 of 45 maths problems
So, the remaining number of maths problems = 1 - 5/9
The remaining number of maths problem = (9 - 5)/9
The remaining number of maths problem = 4/9 of 45
Amount of time to solve 1 problem = 3/5 of a minute
Amount of time to solve 4/9 problems = 45×4/9 × 3/5 of a minute.
Hence, 45 times startfraction 4 over 9 endfraction times three-fifths is the correct expression to find the time.

The equation that best represents this relationship given in the table is y = 56x.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have a table below that shows the number of hours the Carrera family has been driving and the number of miles they’ve driven.
We can find the slope of the line from the table as follows -
m = (168 - 84)/(3 - 1.5)
m = 56
Now, we can write -
y = 56x + c
84 = 56 x 1.5 + c
c = 0
So, the equation would be -
y = 56x
Therefore, the equation that best represents this relationship given in the table is y = 56x.

The standard form of quadratic function is f(x) = 1(x-2)2 - 6
A quadratic function is a two-degree function. A parabola is the graph of a quadratic function. A quadratic function has the general form f(x)=ax2+bx+c, where a, b, and c are real numbers and a0. A quadratic function has the standard form f(x)=a(xh)2+k. The vertex (h,k) has the coordinates h=-b2a,k=f(h)=f(b2a).
Given points (5,3) and (2,-6)
We know that the General form of a quadratic function is
f(x) = ax2+bx+c
Standard form = a(x-h)2 + k
Here point(x,y) = (5,3) and vertex (h,k) = (2,-6)
y = a(x-h)2 + k
3 = a(5-2)2 – 6
3 = a(3)2 – 6
3 + 6 =9a2
9= 9a2
a2 = 9/9
a2=1
a=1

f(x) = 1(x-2)2 – 6

Half of A's money plus one, fifth of B's makes #100. Two
Thirds of A's money plus two-fifth of B's makes # 150.
How much money has each?
The money A has is #150 and the money B has is #125.
According to the question,
We have the following information:
Half of A's money plus one-fifth of B's makes #100. Two-thirds of A's money plus two-fifth of B's makes # 150.
So, we will convert these verbal phrases into expression.
Now, let's take the amount of A to be #x and the amount of B to be #y.
x/2 + y/5 = 100
Using the least common factor of 2 and 5:
5x+2y = 1000
5x = 1000-2y ...(1)
2x/3 + 2y/5 = 150
Adding the fractions using the least common multiple of 3 and 5:
(10x+6y)/15 = 150
Using the cross multiplication method:
10x+6y = 2250
Now, putting the value of 5x from equation 1:
2(1000-2y)+6y = 2250
2000-4y+6y = 2250
2y = 2250-2000
2y = 250
y = 250/2
y = #125
Now, putting this value of y in equation 1:
5x = 1000-2y
5x = 1000-2*125
5x = 1000-250
5x = 750
x = 750/5
x = #150
Hence, the money A has is #150 and the money B has is #125.

the population of the world in 2010 was 7 billion and the annual growth rate was estimated at 1.2 percent per year. assuming that the world population follows an exponential growth model, find the projected world population in 2044. round your answer to one decimal place.
With annual growth rate of 1.2% per year, the projected world population in 2044 is 10.5 billion
The formula for the exponential growth model is:
X(t) = Xo (1 + r)^t
Where:
X(t) = value of X at time t
Xo = initial value
t = time interval
r = growth rate
Parameters given:
Xo = 7 billion = 7 x 10⁹
t = 2044 - 2010 = 34
r = 1.2% = 0.012
Hence,
X(t) = 7 x 10⁹ (1 + 0.012)³⁴
X(t) = 10.5 x 10⁹ = 10.5 billion
Therefore,
The projected world population in 2044 = 10.5 billion

Solve this system of 3 variables with elimination. Once you eliminate 1 variable to get down to only 2, you can use Desmos but show all work/steps first.
3x − 4y + z = 2
−9x + 12y − 3z = − 6
4x − 2y − z = -16
The value of the x, y, and z for the given system of equations are; x = -2/3, y = -1/2, and z = 1.
First, let us understand the equation:
An equation is an expression that shows the relationship between two or more numbers and variables.
We are given the system of equations;
3x − 4y + z = 2 ...........equation 1
−9x + 12y − 3z = − 6 ...........equation 2
4x − 2y − z = -16 ...........equation 3
Add equation 1 to equation 3, we will get;
(3x − 4y + z ) + (4x − 2y − z ) = 2 -16
7x - 6y = -14 ...........equation 4
Multiply equation 3 by 3 and subtract from equation 2, we will get;
3(4x − 2y − z) - (−9x + 12y − 3z ) = -48 + 6
12x - 6y - 3z + 9x - 12y + 3z = 42
21x - 18y = 42 ...........equation 5
Multiply equation 4 by 3 and add it to equation 4, we will get;
3(-3x + 3z) + (9x + 4z) = 5×3 - 2
-9x + 9z + 9x + 4z = 15 -2
13z = 13
z = 1
Put z = 1 in equation 5, we will get;
-3x + 3×1 = 5
-3x + 3 = 5
-3x = 5 - 3
x = -2/3
y = -1/2
Thus, the value of the x, y, and z for the given system of equations are; x = -2/3, y = -1/2, and z = 1.

The solution of the inequality is x>2 and the graph is attached below.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. When two values are compared, an inequality shows whether one is higher, lower, or simply not equal to the other.
The given inequality is 2x - (3-x) > x + 1,
Now, solving the inequality by opening the bracket,
2x - (3-x) > x + 1
[tex]2x - 3 + x > x + 1[/tex]
3x - 3 > x + 1
Subtracting x from both sides and adding 3 on both sides,
2x > 4
x > 2
So, the graph is attached below and Option D is correct.

Find slope intercept form
Answer: y=x+4
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b where
m is the slope and b is the y-intercept.
Formula for working out the slope: y2-y1/x2-x1
Put the values in the equation: 4-3/0-(-1). Answer is 1/1 which is 1.
y-intercept: put one of the x and y values from the graph into the equation y=mx+b. Here, I'm going to choose the point (0,4).
The equation is now 4=1(0) + b
Working out for equation:
4=0+b
4=b
The final equation is y=x+4.
You can also use the graph to help you find the y-intercept! First, look at the y-axis. Then the point that passes it is your y-intercept!(Remember it's the y value not the x)
