Answer:

0.1358 = 13.58% probability of a fatal collision with a pole or post

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

1416 collisions with pole or post.

1416 + 2516 + 2585 + 896 + 947 + 231 + 1835 = 10426 total collisions.

a. What is the probability of a fatal collision with a pole or post?

[tex]p = \frac{1416}{10426} = 0.1358[/tex]

0.1358 = 13.58% probability of a fatal collision with a pole or post

Answer:

The margin of error for a 99% confidence interval is of 0.0639, that is, approximately 0.06.

The margin of error for a 95% confidence interval is of 0.0486, that is, approximately 0.05.

The margin of error for a 90% confidence interval is of 0.0408, that is, approximately 0.04.

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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

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

350 citizens, 240 responded favorably:

This means that [tex]n = 350, \pi = \frac{240}{350} = 0.6857[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

[tex]M = 2.575\sqrt{\frac{0.6857*0.3143}{350}} = 0.0639[/tex]

The margin of error for a 99% confidence interval is of 0.0639, that is, approximately 0.06.

95% confidence level

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

[tex]M = 1.96\sqrt{\frac{0.6857*0.3143}{350}} = 0.0486[/tex]

The margin of error for a 95% confidence interval is of 0.0486, that is, approximately 0.05.

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

[tex]M = 1.645\sqrt{\frac{0.6857*0.3143}{350}} = 0.0408[/tex]

The margin of error for a 90% confidence interval is of 0.0408, that is, approximately 0.04.

Answer:

X earns $ 2,178.57, as does Z, while Y earns $ 1,742.85.

Step-by-step explanation:

Since an employer pays three workers X, Y and Z a total amount of $ 6100 a month, of which X is paid 125% of the amount Y is paid; which represents 80% of the amount Z is paid, to determine how much does X receive a month the following calculation must be performed:

X = 1.25Y

Y = 0.8Z

Z = Z

Z + Y + X = 6,100

Z + 0.8Z + (1.25 x 0.8Z) = 6,100

Z + 0.8Z + Z = 6,100

2.8Z = 6,100

Z = 6,100 / 2.8

Z = 2,178.57

Y = 0.8 x 2,178.57 = 1,742.85

X = 1,742.85 x 1.25 = 2,178.57

2,178.57 + 2,178.57 + 1,742.85 = X

6,099.99 = X

Thus, X earns $ 2,178.57, as does Z, while Y earns $ 1,742.85.

Answer:

∆ABC ≅ ∆EDF by the SAS Congruence Theorem.

Step-by-step explanation:

<A ≅ <E,

Side length AC ≅ Side length EF

Side length AB ≅ Side length ED,

Thus, this implies that an included angle and two sides of one triangle are congruent to an included angle and 2 corresponding side lengths of the other triangle.

Therefore, we would conclude that:

∆ABC ≅ ∆EDF by the SAS Congruence Theorem.

The total distance of Kite from the ground is 16.38 meters and this can be determined by using the trigonometric function.

Given :

The following steps can be used in order to determine the total distance of Kite from the ground:

Step 1 - The trigonometric functions can be used in order to determine the total distance of Kite from the ground.

Step 2 - The sine function is used to measure the distance. The mathematical expression of the sine function is:

[tex]\rm sin\theta = \dfrac{P}{H}[/tex]

where P is the perpendicular and H is the hypotenuse.

Step 3 - Now, substitute the values of the known terms in the above expression.

[tex]\rm sin55 = \dfrac{Distance}{20}[/tex]

Step 4 - Simplify the above expression.

Distance = 16.38 meters

Answer:

The 10th percentile is 66.42.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

X ~ N(70, 14).

This means that [tex]\mu = 70, \sigma = 14[/tex]

Suppose that you form random samples of 25 from this distribution.

This means that [tex]n = 25, s = \frac{14}{\sqrt{25}} = 2.8[/tex]

Find the 10th percentile.

This is X when Z has a pvalue of 0.1, so X when Z = -1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]-1.28 = \frac{X - 70}{2.8}[/tex]

[tex]X - 70 = -1.28*2.8[/tex]

[tex]X = 66.42[/tex]

The 10th percentile is 66.42.

Step-by-step explanation:

correct on edge 2021

Option (B) parabola with a vertex (–2, 3) opening to the right, and option (E) quadrant 3 is not shaded at all are correct.

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have given a parabolic inequality:

x ≥ (y – 3)² – 2

After plotting on the graph:

parabola with a vertex (–2, 3) opening to the right

quadrant 3 is not shaded at all

Thus, option (B) parabola with a vertex (–2, 3) opening to the right, and option (E) quadrant 3 is not shaded at all are correct.
