5. A student project asked an SRS of 172 college freshman at a large university "Would you

c. Confidence Interval=

Answers
The 97% confidence interval for the proportion of college freshmen who would report cheating if they witnessed it in class is (0.0728, 0.1482).
The point estimate is the proportion of students who responded "yes" out of the total sample.
In this case, the point estimate is 19/172, which is approximately 0.1105.
b. Margin of Error:
To calculate the margin of error, we need the standard deviation. Since we don't have the population standard deviation, we'll use the formula for the estimated standard deviation of a proportion:
Margin of Error (ME) = z√[(p(1 - p)) / n]
Where z is the z-score corresponding to the desired confidence level. For a 97% confidence level, the z-score is approximately 1.96, p is the point estimate of the proportion and n is the sample size.
Using the given values, we can calculate the margin of error:
ME = 1.96√[(0.1105(1 - 0.1105)) / 172]= 0.0377
c. Confidence Interval:
The confidence interval is calculated by subtracting and adding the margin of error from the point estimate.
Confidence Interval = Point Estimate ± Margin of Error
Confidence Interval = 0.1105 ± 0.0377

Answers
The points that are solutions to the equation [tex]2x^2 + y = 4[/tex] are:
I. (3, -14)
III. (-3, -14)
To determine which of the given points are solutions to the equation [tex]2x^2 + y = 4[/tex], we need to substitute the x and y values of each point into the equation and check if the equation holds true.
Let's evaluate each point one by one:
I. (3, -14)
Substituting x = 3 and y = -14 into the equation:
[tex]2(3)^2 + (-14) = 4[/tex]
18 - 14 = 4
4 = 4
Since both sides of the equation are equal, the point (3, -14) is a solution to the equation.
II. (-3, 14)
Substituting x = -3 and y = 14 into the equation:
[tex]2(-3)^2 + 14 = 4[/tex]
18 + 14 = 4
32 = 4
Since the equation is not satisfied (32 is not equal to 4), the point (-3, 14) is not a solution to the equation.
III. (-3, -14)
Substituting x = -3 and y = -14 into the equation:
[tex]2(-3)^2 + (-14) = 4[/tex]
18 - 14 = 4
4 = 4
Since both sides of the equation are equal, the point (-3, -14) is a solution to the equation.

[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The margin of error is defined as follows:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
We have no estimate, hence the proportion is used as follows:

For a margin of error of 0.04, the sample size is obtained as follows:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.04 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

Answers
Tamika Clark's total travel expense this month is $362.90.
Given that the supervisor for the county is Tamika Clark.
Every month, she makes the trip to the three schools in her district.
Her travel costs for this month include 246 miles at a cost of $0.55 per mile, $180.70 for meals, and $46.10 for other expenses.
We must determine the whole cost of her.
To calculate Tamika Clark's total travel expenses this month, we need to add up her expenses for miles traveled, meals, and miscellaneous items.
Miles traveled:
246 miles x $0.55 per mile = $135.30
Meals: $180.70
Miscellaneous: $46.90
Total travel expenses:
$135.30 (miles traveled) + $180.70 (meals) + $46.90 (miscellaneous) = $362.90
Therefore, Tamika Clark's total travel expense this month is $362.90.

You can find B by multiplying 4 by 7 (because the other part of that side of the square is 3 so that part would be 7) which would be 28, then since it is a right triangle, you can divide that by two and get 14.
You can find C by multiplying 10 times 3 and getting 30, then since it is a right triangle, you can divide that by two and get 15.
You can find D by multiplying 10 by 10 (because it is a square) then you'll get 100 from that. Then you can subtract the rest of the triangles from it which would be 100 minus 30 minus 14 minus 15 and you would get 41 which would be triangle D.

the midline is y = d, so y = 0 and there's no vertical shift
the vertical stretch is 1, so label the y-axis so the inflection point of the curve is 1 above the midline, 1, and the other inflection point is 1 below the midline, −1
the period is:

A rocket is launched in the air. Its height in feet is given by h= -16t^2 + 56t where t represents the time in seconds after launch. What is the appropriate domain for this Solution?
Answers
The domain of the function (t) in h = - 16t² + 56t should be greater than
or equal to 43.5 seconds as the height of the rocket can not be negative.
Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given that;
A rocket is launched into the air. Its height in feet is given by
h = - 16t² + 72t.
Where t represents time in seconds and h represents the height in feet.
We know that height can not be negative.
h ≥ 0.
So, - 16t² + 56t ≥ 0.
- 16t² ≥ -56t.
16t² ≥ 56t.
16t ≥ 56.
t ≥ 56/16.
t ≥ 3.5 seconds.
Therefore, the domain of the function (t) in h = - 16t² + 56t should be greater than or equal to 3.5 seconds.

If side a measures 30 feet and side b measures 40 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work.
Answers
Answer:
You dont have to tell me to show my work twice
Step-by-step explanation:
To find the length of side c (the hypotenuse), we will use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (a and b) is equal to the square of the hypotenuse (c).
In this case, a = 30 feet and b = 40 feet. Therefore:
c^2 = a^2 + b^2
c^2 = 30^2 + 40^2
c^2 = 900 + 1600
c^2 = 2500
c = √2500
c = 50 feet
So the length of side c (the hypotenuse) is 50 feet. To find out how many feet of flowers will be planted along side c, we need to know the perimeter of the triangle (the sum of the lengths of all three sides). The perimeter is:
Perimeter = a + b + c
Perimeter = 30 + 40 + 50
Perimeter = 120 feet
Therefore, 120 feet of flowers will be planted along side c.
Answer: Here, side a = 30ft.
side b = 40ft.
Hence according to, Pythagoras theorem,
h²=p²+b²
where, h= hypotenuse of the triangle
b= base of the triangle
p= perpendicular of the triangle
Step-by-step explanation:
hypotenuse c {according to question} - c=[tex]\sqrt{a^{2} + b^{2}[/tex]
therefore, c=[tex]\sqrt{30^{2} + 40^{2} }[/tex] = 50ft. will be the answer.
Hypotenuse means the longest side of the triangle or in other words the side opposite to the 90° angle of the triangle.
I need help can someone help me

Answer:
x ≈ 12.7
Step-by-step explanation:
since the triangle is isosceles then the 2 legs are congruent, both 9
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 9² + 9² = 81 + 81 = 162 ( take square root of both sides )
x = [tex]\sqrt{162}[/tex] ≈ 12.7 ( to the nearest tenth )
Answer:
Solution is in the attached photo.
Step-by-step explanation:
This question tests on the concept of triangles, as this is an isosceles triangle, the other 2 unknown angles are the same, as well as the sine rule.
