A politician claims that a proposal for a new traffic law is broadly supported by both political parties and that a person from either political party is equally likely to support the proposed legislation. He cites two recent polls that said 70% of a random sample of 550 people from his political party supports the law, and 65% of a random sample of 420 people from the other political party supports the law. The 95 percent confidence interval for the difference in population proportions is (–0.010, 0.110). Based on the interval, is the politician’s claim justified?

Answers

Answer 1

Answer:

Based on the 95% confidence interval for the difference in population proportion, there is convincing statistical evidence that he is correct

Step-by-step explanation:

The proportion from the sample of people from his party that support the law = 70%

The number the members of the politicians political party that support the law = 550 people

The proportion from the sample of people from the other party that support the law = 65%

The number the members of the politicians political party that support the law = 420 people

The confidence level of the test = 95%

The given confidence interval for the difference in proportion, C.I. = (-0.010, 0.110)

Given that the 95% confidence interval for the difference in population proportion ranges from -0.010, to 0.110, it is 95% certain that 0 is among the likely difference in proportion between the two populations and therefore, there is sufficient statistical evidence to suggest that there is no difference in the proportion of the members of either political that support the proposed new traffic law.

Write an equation for the nth term of each arithmetic sequence: 45, 30, 15, 0, …

Answers

Answer:

[tex]a_{n}[/tex] = 60 - 15n

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 45 and d = a₂ - a₁ = 30 - 45 = - 15 , then

[tex]a_{n}[/tex] = 45 - 15(n - 1) = 45 - 15n + 15 = 60 - 15n

An equation for the nth term of the arithmetic sequence is aₙ=60-15n.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.

The given arithmetic sequence is 45, 30, 15, 0,.....

Here, a=45 and d=30-45 = -15

Now, aₙ=45+(n-1)(-15)

aₙ=45-15n+15

aₙ=60-15n

Therefore, an equation for the nth term of the arithmetic sequence is aₙ=60-15n.

For numbers 11-16 Find x, y, and z for each. Show all work.

Answers

Answer:

x=74

y=37

z=25

Step-by-step explanation:

First, we can find y.

106 and 2y are supplementary angles. That means that when added together, they equal 180.

106+2y=180

2y=74

y=37

We can use this information to help us find x.

x and 2y are corresponding angles, which means that they are congruent.

2y=x

2(37)=x

74=x

Now, let's find z.

4z+6 is corresponding to the angle right above angle x. This means that (4z+6)+x=180.

Let's solve.

(4z+6)+74=180

4z+80=180

4z=100

z=25

Step-by-step explanation:

(3)(4x)+(3)(6)=x+−4(Distribute)

12x+18=x+−4

12x+18=x−4

Step 2: Subtract x from both sides.

12x+18−x=x−4−x

11x+18=−4

Step 3: Subtract 18 from both sides.

11x+18−18=−4−18

11x=−22

Step 4: Divide both sides by 11.

A square has an area of 313.29m2.
Work out the perimeter of the square.

Answers

The perimeter of the square is 70.8 meters.

To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².

The formula for the area of a square is:

Area = side length²

We can rearrange this formula to solve for the side length:

Side length = √Area

Substituting the given area into the formula, we have:

Side length = √313.29 m²

Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).

Since a square has four equal sides, the perimeter is simply four times the side length:

Perimeter = 4 * 17.7 m = 70.8 meters

As a result, the square's circumference is 70.8 metres.

A horse's paddock is triangular with a height of 76 ft and sides of 114 ft, 102 ft, and 53 ft. What is the cost of fencing around the paddock if the fencing costs $5.40 per ft?

Answers

Answer:

$1452.6

Step-by-step explanation:

To obtain the cost of fencing round a triangular paddock, we obtain the perimeter. The perimeter of a triangle is given as :

Perimeter = a + b + c ; where a, b and c are the length of the three sides of the triangle.

The perimeter of the paddock in this scenario is :

(114 + 102 + 53) feets = 269 feets ; which are the lengths of the 3 sides of the triangular paddock.

Painting Cost per feet = $5.40

Cost per feet * number of feets

$5.40 * 269

= $1452.6
