Find the critical value necessary to form a confidence interval at the level of confidence shown below.

c=0.87

Answers

Answer:

the critical value for 0.87 level of confidence is 1.51

Step-by-step explanation:

Given the data in the question;

level of confidence = 0.87

now,

1 - c = 0.87

c = 1 - 0.87

c = 0.13

c/2 = 0.13/2 = 0.065

now

1 - c/2 = 1 - 0.065 = 0.935

so our level of significance ∝ = 0.935

Now, the critical value will be;

[tex]Z_{0.935[/tex] is obtained as follows;

P( Z < z ) = 0.935

so we find the value from ( standard normal distribution table )

P( Z < 1.51 ) = 0.935

Therefore, the critical value for 0.87 level of confidence is 1.51

Answer:

r ≈ 15.90 mP ≈ 63.27°Q ≈ 26.73°

Step-by-step explanation:

The triangle is a right triangle, so the length of r can be found using the Pythagorean theorem.

r = √(14.2² +7.15²) = √252.7625

r ≈ 15.8985 ≈ 15.90 . . . meters

The angles can be found from the tangent relation.

Tan = Opposite/Adjacent

tan(P) = 14.2/7.15

P = arctan(14.2/7.15) ≈ 63.2738° ≈ 63.27°

Angle Q is the complement of angle P.

Q = 90° -63.27° = 26.73°

of 400 cm. What is the length of the rectangle?
A. 3 cm
B. 30 cm
C. 300 cm
D. 3000 cm

Answers

Answer:

L = 3 cm

Step-by-step explanation:

let lenght be L

First convert area in cm

1 m = 100 cm

12 m = 1200 cm

Area of rectangle = width x lenght

1200 cm = 400 cm x L

1200 /400 = L

3 cm = L

The mean age of all 618 used cars for sale in a newspaper one Saturday last month was 7.7 years, with a standard deviation of 7.3 years. The distribution of ages is right-skewed. For a study to determine the reliability of classified ads, a reporter randomly selects 30 of these used cars and plans to visit each owner to inspect the cars. He finds that the mean age of the 30 cars he samples is 8.3 years and the standard deviation of those 30 cars is 5.7 years.

Required:
From the problem statement, which of the values 7.7, 7.3, 8.3, and 5.7 are parameters and which are statistics?

Answers

Answer:

7.7 and 7.3 are the parameters

8.3 and 5.7 are statistics

Step-by-step explanation:

In the given question,

7.7 and 7.3 represents the mean and standard deviation for all of the used cars for sale.

So,

It represents the population mean and standard deviation

So,

7.7 and 7.3 are the parameters .

Now,

8.3 and 5.7 is mean and standard deviation for sample , not for population.

∴ 8.3 and 5.7 are statistics.

Step-by-step explanation:

36/12 = 3 cm

Answer:Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a two-dimensional shape is the space occupied by the shape.

Answer:

x = 18y = 9

Step-by-step explanation:

The ratios of side lengths in a 30°-60°-90° triangle are ...

1 : √3 : 2

In the same order, the given side lengths are ...

y : 9√3 : x

Comparing these two sets of ratios, we see that we can make the first equal to the second by multiplying by 9:

9(1) : 9√3 : 9(2) = y : 9√3 : x

Then y = 9·1 = 9, and x = 9·2 = 18.

The missing side lengths are x = 18, y = 9.

Add 2 to both sides.

−6y>10+2

Add 10 and 2 to get 12.

Divide both sides by −6. Since −6 is negative, the inequality direction is changed.

y<12/-6

Divide 12 by −6 to get −2.

Substituting the y into the other equation

-3x-2(5x-7)=-12

-3x-10x+14=-12

-13x=-14-12

-13x=-26

x=2

We have x=2 then substitute it into the first equation

A square has side length 3 units. What is the length of the diagonal?
A. 3 units
B. 3/√2 units
C. 3√2 units
D. 6 units

Answers

Answer:

Step-by-step explanation:

The diagonal can be represented as the hypotenuse of a right triangle with 3 and 3 as its legs. Use the pythagorean theorem to get that 3^2+3^2=c^2. Simplify to 9+9=c^2 or 18=c^2. Square root both sides to get c=√18. Simplify to get c=√9*2 or c=3√2 for the diagonal.

The length of the diagonal of the square is (b) [tex]3\sqrt 2[/tex] units

The length of the diagonal of a square is calculated using the following Pythagoras theorem

[tex]d^2 = l^2 + l^2[/tex]

Where:

d represents the length of the diagonall represents the side length of the square

So, we have:

[tex]d^2 = 3^2 + 3^2[/tex]

Evaluate the like terms

[tex]d^2 = 2(3^2)[/tex]

Take the square roots of both sides

[tex]d =3\sqrt2[/tex]

Hence, the length of the diagonal of the square is (b) [tex]3\sqrt 2[/tex] units
