Answer:

B

Step-by-step explanation:

It passes the vertical line test. Going up and down it doesn't touch the line at two separate points at any time.

According to the p-value, the correct option regarding the decision of the test hypothesis is:

v. No, because 0.283 > 0.05.

At the null hypothesis, we test if the proportion is still of 0.53, that is:

[tex]H_0: p = 0.53[/tex]

At the alternative hypothesis, we test if it has increased, that is:

[tex]H_1: p > 0.53[/tex].

In this problem, the p-value is of 0.283 > 0.05, hence there is not sufficient evidence to conclude, at the significance level of a = 0.05, that the proportion of all car owners in the United States who own American-made cars has increased from what it was ten years ago, which means that option V is correct.

The probability of 2 green outcomes and 2 orange outcomes when you roll the number cube 4 times is 0.116.

Assuming that it is a fair number cube, the probability of getting green is given by the quotient between the outcomes that give the color green and the total number of outcomes.

We know that there are 5 green sides (so 5 outcomes give the color green) and the dice has 6 sides (so there is a total of 6 outcomes). Then the probability of rolling green is:

P = 5/6.

The probability of rolling orange is computed in the same way, 1 outcome gives the color orange and there are 6 outcomes in total, so the probability of getting orange is:

Q = 1/6.

Now, let's assume that when we roll four times we get:

green - green - orange - orange.

The probability of that is given by the product of the individual probabilities, it is:

p = P*P*Q*Q = (5/6)*(5/6)*(1/6)*(1/6).

Now, we also need to take in account all the possible permutations, these are:

So there are 6 permutations, to get the total probability of rolling 2 green outcomes and 2 orange outcomes, we need to multiply this number by the probability we got above.

Probability = 6p = 6* (5/6)*(5/6)*(1/6)*(1/6) = 0.116

Answer:

V = 564.2 m^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h  where r is the radius and h is the height

V = 1/3 pi (7)^2 (11)

V =539 /3 * pi

Letting pi be approximated by 3.14

V = 564.1533333 m^3

Rounding to the nearest tenth

V = 564.2 m^3

Answer:

564.512 m³

Step-by-step explanation:

Formula to find the volume of a cone is :

Volume = [tex]\frac{1}{3}[/tex] π r² h

Here,

r = radius = 7 m

h =  height = 11 m

Let us solve now.

Volume = [tex]\frac{1}{3}[/tex] π r² h

Volume = [tex]\frac{1}{3}[/tex] π ×7² × 11

Volume = [tex]\frac{1}{3}[/tex] π × 49 × 11

Volume = [tex]\frac{1}{3}[/tex] π × 539

Volume = [tex]\frac{1}{3}[/tex] × 1693.538

Volume = 564.512 m³

Answer:

x ≈ 31.8

Step-by-step explanation:

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 + 12² = 34²

x² + 144 = 1156 ( subtract 144 from both sides )

x² = 1012 ( take square root of both sides )

x = [tex]\sqrt{1012}[/tex] ≈ 31.8 ( to the nearest tenth )

Answer:

20.8

Step-by-step explanation:

[tex]24 = \sqrt{ {12}^{2} + {x}^{2} } [/tex]

[tex] {24}^{2} = 144 + {x}^{2} [/tex]

[tex]576 - 144 = {x}^{2} [/tex]

Answer:

16 cm

Step-by-step explanation:

A right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.

Since this is a right triangle, use the pythagorean theorem to find the value for x.

let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.

The pythagorean theorem is: c^2 = a^2 + b^2.

18^2 = 7^2 + x^2324 = 49 +x^2

x^2 = 324 - 49 = 275So, x = sqrt(275) = 16.5 cm

Step-by-step explanation:

A) The probability of Lisa being correct if she says a drink is flat is; 83.3%

B) The level of Lisa's accuracy in detecting a drink that is flat is; 83.3%

C) The reason why Lisa should be considered for to job is because; she has a high accuracy level and is not just complaining unnecessarily.

From the table showing Lisa's response to the last 100 drinks she bought attached, we see that;

A) When the drink was flat, she complained 5 times out of 6. Thus, if the drink is flat, the probability of her complaint being correct = 5/6 = 83.3%

B) Since she is 83.3% correct in detecting whether a drink is flat, then we can say that Lisa is 83.3% very good at detecting whether a drink is flat.

C) It would be good in recommending Lisa for the quality control job because she only complained 3 times out of 94 times that the drink was not flat while she was correct 5 out of 6 times when the drink was flat. Thus, she has a high accuracy level and is not just complaining unnecessarily.

Answer:

43°

Step-by-step explanation:

A triangle has a total angle of 180° and we can use it to find the answer.

The attachment is a visualization of the triangle.

In order to find angle T, we can use the triangle formula to find t.

[tex] {180}^{o} = r + s + t[/tex]

By substituting r and s, we will get

[tex] {180}^{o} = {85}^{o} + {52}^{o} + t[/tex]

Hence, we can find T, which is

[tex]t = {180}^{o} - {85}^{o} - {52}^{o} = {43}^{o} [/tex]
