Education and health services
Step-by-step explanation:
It has had the most increase over the years, so it will most likely keep increasing and let you get more wages and job opportunities.
In October of 2019, Gallup asked a random sample of 1,506 Americans which of two approaches to punishing murder they thought was better, the death penalty or life without possibility of parole. For the first time since Gallup began asking the question in 1985, a majority of Americans now say life imprisonment is a better approach for punishing murder than is the death penalty. According to the 2019 Gallup death-penalty poll, 60% percent of Americans asked to choose whether the death penalty or life without possibility of parole "is the better penalty for murder" chose the life-sentencing option. 36% favored the death penalty.
Required:
a. Find a 95% confidence interval for the proportion adults in the US that now believe life imprisonment is a better approach for punishing murder.
b. Interpret your interval above in the context of this problem.
c. Use your interval to find the margin of error associated with this confidence interval.
d. If we increase the level of confidence to 98%, will the interval be wider or narrower?
Answer:
a
The 95% confidence interval is \(0.5753< p <0.62474\)
b
This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval
c
The margin of error is \(E = 0.02474 \)
d
The confidence interval becomes wider
Step-by-step explanation:
From the question we are told that
The sample size is n = 1506
The sample proportion is \(\^ p = 0.60\)
From the question we are told the confidence level is 95% , hence the level of significance is
\(\alpha = (100 - 95 ) \%\)
=> \(\alpha = 0.05\)
Generally from the normal distribution table the critical value of \(\frac{\alpha }{2}\) is
\(Z_{\frac{\alpha }{2} } = 1.96\)
Generally the margin of error is mathematically represented as
\(E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } \)
=> \(E = 1.96 * \sqrt{\frac{0.60 (1- 0.60)}{1506} } \)
=> \(E = 0.02474 \)
Generally 95% confidence interval is mathematically represented as
\(\^ p -E < p < \^ p +E\)
=> \(0.60 - 0.02474 < p <0.60 + 0.02474\)
=> \(0.5753< p <0.62474\)
This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval
Generally the level of confidence varies directly with the critical value of \(\frac{\alpha }{2}\) and this in turn varies directly with the margin of error which when sample proportion is constant it determines the width of the confidence interval so when the level of confidence increases the confidence interval becomes wider
order from least to greatest 1/2, -2/3,-1 1/6,-1/6
Answer:
-1 1/6, 4/6, 1/6, 1/2
Step-by-step explanation:
The first thing we have to do is find the G.C.D so that all the denominators are equal:
-4/6, -1 1/6, -1/6 you can't really change the 1/2 but since it is the only positive number you know it goes last.
when it comes to ordering negatives from least to greatest less is more. By this, I mean that the greater the number is the less it is worth. I hope that made sense anyway the greatest negative number is -1 1/6 so that goes first in the order next -4/6 since it is less than -1/6 which ofc goes next. Lastly, 1/2 which as we mentioned before is positive so ofc it goes last.
Hence the order is, -1 1/6, 4/6, 1/6, 1/2

If z = 2 [ cos ( - π 4 ) + i sin ( - π 4 ) ] = a + b i in rectangular form, then a = and b = .
The complex number in rectangular form is z = √2 - i√2
What is rectangular form of complex numbers?The rectangular form of of a complex number is given by z = a + ib where
a = rcosФ and b = rsinФwhere
r = magnitude of complex number and Ф = argument of complex numberHow to find the given complex number in rectangular form?Given the complex number
z = 2[cos(- π/4) + isin(- π/4)] , we desire to find the rectangular form of the complex number. We proceed as follows.
z = 2[cos(- π/4) + isin(- π/4)]
z = 2cos(- π/4) + i2sin(- π/4)]
z = 2cos(π/4) - i2sin(-π/4)]
Since cos(π/4) = sin(π/4) = 1/√2, we have that
z = 2cos(π/4) - i2sin(-π/4)]
z = 2 × 1/√2 - i2 × 1/√2
z = 2/√2 - i2/√2
Rationalizing the denominators, we have that
z = 2/√2 × √2/√2 - i2/√2 × √2/√2
z = 2√2/2 - i2√2/√2
z = √2 - i√2
So, we have the number in rectangular form as z = √2 - i√2

given the function: f(x)=x^2-2x. how can you restrict the domain so that f(x) has an inverse? what is the equation of the inverse function?
Solution
We have the following equation given:
\(y=x^2-2x=x(x-2)\)For this case we can do the following:
\(x=y^2-2y=y(y-2)\)We can solve for the quadratic equation and we got:
\(y=\frac{-(-2)\pm\sqrt[]{(-2)^2-4(1\cdot-x)}}{2\cdot1}=\frac{2\pm\sqrt[]{4\cdot(1+x)}}{2}=1\pm\sqrt[]{1+x}\)The two solutions are:
\(y_1=1-\sqrt[]{1+x},y_2=1+\sqrt[]{1+x}\)Then the answer is:
Part 1
\(x\ge1\)Part 2
\(f^{-1}(x)=1+\sqrt[]{1+x}\)find all the points (x,6) that are 10 units from the point P (-17,-2)
Answer:
The points that are 10 units from P(-17,-2) are (-23,6) and (-11,6)
Step-by-step explanation:
Distance Between Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
\(d=\sqrt{(z-y)^2+(w-x)^2}\)
It can be also expressed as:
\(d^2=(z-y)^2+(w-x)^2\)
Substituting the values of both points, and knowing the distance is 10:
\(10^2=(6-(-2))^2+(x+17)^2\)
\(100=8^2+(x+17)^2\)
Swapping both sides:
\(64+(x+17)^2=100\)
Moving the constants to the right side:
\((x+17)^2=100-64=36\)
Taking the square root:
\(x+17=\pm 6\)
We get two possible answers:
\(x=-17-6=-23\)
\(x=-17+6=-11\)
Thus the points that are 10 units from the point P(-17,-2) are (-23,6) and (-11,6)

The United States' decision to remain neutral was motivated by its over $1 billion in annual trade with Europe.
Why did American neutrality benefit from commerce with Europe?Early 20th-century American trade with Europe helped the US remain neutral by enabling it to maintain business ties with both the Allied and Central Powers.
The US was able to avoid taking a political stance and maintain its neutral status by supplying goods to both sides of the conflict. Additionally, trade helped the US maintain its economic stability because it would have been detrimental to the nation's economy to break off trade with one party.

If it were physically possible, how many folds would it take to make the paper as tall as you are? (1 in.=2.54 cm)
If the paper is a bond paper, then we need between an amount of 16750 and 22334 folds for a height of 67 inches.
How many folds of paper are necessary to reach the height of a student?
In this problem we need to determine that number of elements in a paper whose folds creates a height to the height of the person. We assume that paper is a bond papel, whose thickness is 0.003 to 0.004 inches. The number of folds is equal to the height of the student in inches divided by the thickness, also in inches.
Let suppose that the height of the student is 67 inches (approx. 170 cm), then the number of papers in a batch with same height is:
n = 67 in / 0.003 in
n = 22334
n = 67 in / 0.004 in
n = 16750

how to solve this separable differential equation?
The solution to the differential equation \(2^{\sqrt{x}}\frac{dy}{dx} = cosce(ln(y))\) is,
\(\frac{y sin(ln(y))}{2} - \frac{y cos(ln(y))}{2} = C - \frac{2 ln(2) \sqrt{x} + 2}{ln^2(2)2^{\sqrt{x}}}\).
What is a differential equation?Any equation with at least one ordinary or partial derivative of an unknown function is referred to as a differential equation.
The given differential equation is \(2^{\sqrt{x}}\frac{dy}{dx} = cosce(ln(y))\).
Now, multiplying both sides by dx we,
\(2^{\sqrt{x}}dy = cosce(ln(y))dx\).
Dividing both sides by \(2^{\sqrt{x}}\) we have,
\(sin(ln(y))dy = \frac{dx}{2^{\sqrt{x}}}\).
\(\[ \int sin(ln(y))dy = \int \frac{dx}{2^{\sqrt{x}}}\).
\(\frac{y sin(ln(y))}{2} - \frac{y cos(ln(y))}{2} = C - \frac{2 ln(2) \sqrt{x} + 2}{ln^2(2)2^{\sqrt{x}}}\).

Given:
A man is dieting for three weeks
The man loses 5 5/6 pounds the first week, 5 4/5 pounds the second week, and 3 2/3 pounds the third week
So, the sum of the pounds =
\(5\frac{5}{6}+5\frac{4}{5}+3\frac{2}{3}=\frac{153}{10}\)So, the average weekly weight loss =
\(\frac{153}{10}\div3=\frac{153}{10}\times\frac{1}{3}=\frac{153}{30}=\frac{51}{10}=5\frac{1}{10}\)So, the answer will be:

What is the equation of the line that passes through the point (-3, 7) and has a slope of -5/3?
The equation of the line that passes through the point (-3, 7) and has a slope of -5/3 is y - 7 = (-5/3)(x + 3).
We are given the point (-3, 7) and the slope of the line as -5/3.The slope-intercept form of a line is y = mx + b where m is the slope and b is the y-intercept.
To obtain the equation of the line, we need to substitute the values of slope and point in the slope-intercept form and solve for b.(7) = (-5/3)(-3) + b 21/3 = b.
Now we have the value of b, and we can substitute the values of m and b in the slope-intercept form.y = (-5/3)x + 21/3 is the equation of the line in slope-intercept form.
To obtain the equation in the standard form Ax + By = C, we multiply each term by 3.3y = -5x + 7Add 5x to both sides5x + 3y = 7.
This is the equation of the line in standard form.
