Answer:

B

Step-by-step explanation:

Answer: The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.

Step-by-step explanation:

The statement that is true about the result considering a significance level of 5% is B. The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.

This refers to the analysis of numbers and data to make an inference about a thing.

Hence, we can see that based on the research made about the growth rate of corn, we can see that from the significance level of 5%, we can see that spraying the corn plants with the new type of fertilizer does increase the growth rate.

Answer:

Step-by-step explanation:

The probability that a birth in the United States is male during 2018 is 0.511. So there are slightly more males than females born.

In 300  simulated trials, 171 of the births are female and 129 are male. More females are born so it is not consistent with the model.

The expected number of male birth for 300 trials should be 300*0.511 = 153.

The expected number of female = 300-153 = 147

Step-by-step explanation:

Sum of interior angles of a pentagon = 540°

Therefore,

2x° +2x° + 3x° + 3x° + 10 = 540°

10x° + 10° = 540°

10x° = 540° - 10°

10x° = 530°

10x = 530

x = 530/10

Answer:

  735.6 in³

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr³ . . . . where r is the radius

The radius is half the diameter, so we can write this in terms of diameter as ...

  V = (4/3)π(d/2)³ = (π/6)d³

Using the given diameter, the volume is ...

  V = (π/6)(11.2 in)³ ≈ 735.6186 in³

The volume is about 735.6 cubic inches.

Answer:

The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

In a survey of 802 U.S. adult drivers, 265 state that traffic is getting worse in their community.

This means that [tex]n = 802, \pi = \frac{265}{802} = 0.3304[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 - 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.2978[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 + 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.3630[/tex]

The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).

Answer:

  c. no

  d. yes; AA postulate

Step-by-step explanation:

c. The marked sides have the same ratio ...

  20/14 = 10/7 = 64/44.8

However, the angle between them is not marked as being the same. We cannot conclude the triangles are similar.

__

d. Missing angle R is 180° -32° -52° = 96°. So, two of the angles in the triangles match. (32° and 96°) ∆RQJ ~ ∆VKX by the AA postulate.

To simplify this expression, first use the distributive property to distribute [tex]\frac{1}{2}[/tex].

[tex]9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)[/tex]

Simplify.

[tex]9y+-2y+-10[/tex]

Combine like terms, [tex]9y[/tex] and [tex]-2y[/tex].

Answer:

96

Step-by-step explanation:

Out of 270 apartments in a complex, 174 are subleased.

Given that :

Total number of apartments in complex = 270

Number subleased = 174

The complement of event A = not A

Therefore, The complement in this scenario is NOT SUBLEASED ;

Hence, the Number of apartments in complex not subleased is :

Total apartment in complex - number subleased

270 - 174 = 96

Answer:

17is the truth

Step-by-step explanation:

Answer:

P(X, Y) = 1/(20.398 ) if X ∈ (2, 8.2) and Y ∈ (3.01, 6.3)

P(X, Y) = 0 if  X ∉ (2, 8.2) and Y ∉ (3.01, 6.3)

Step-by-step explanation:

We know that the possible values of X (all with the same probability) are:

2 < X < 8.2

And for Y we have the range (also uniform):

3.01 < Y < 6.3

Then we have a rectangle of area.

(8.2 - 2)*(6.3 - 3.01) = 20.398

Such that the probability for all the points inside the rectangle should be exactly equal, then we will have:

P(X, Y) = 1/(20.398 ) if X ∈ (2, 8.2) and Y ∈ (3.01, 6.3)

Such that if we integrate this in the given region, the integral will be equal to 1, as we should expect.

And zero if the point is outside that region, this is:

P(X, Y) = 0 if  X ∉ (2, 8.2) and Y ∉ (3.01, 6.3)
