a. The population of taxi drivers in Greece falls between 3.3766 meters and 4.0234 meters.

b. The assumption is that the sample of 50 taxi drivers is representative of the population.

a.

To construct a 95% confidence interval for the population mean following distance while talking on a mobile phone, we can use the formula:

Confidence Interval = sample mean ± (critical value × standard error)

The standard error:

Standard Error = sample standard deviation / √(sample size)

Standard Error = 1.17 / √(50)

Standard Error = 0.165

Since the sample size is large (n > 30), we can use the Z-table to find the critical value.

For a 95% confidence level, the critical value is approximately 1.96.

Now we can construct the confidence interval:

Confidence Interval = 3.70 ± (1.96 × 0.165)

Confidence Interval = 3.70 ± 0.3234

Confidence Interval = (3.3766, 4.0234)

Interpretation: We are 95% confident that the true population means following distance while talking on a mobile phone for the population of taxi drivers in Greece falls between 3.3766 meters and 4.0234 meters.

b.

The assumption that must be made to generalize this confidence interval to the population of all taxi drivers in Greece is that the sample of 50 taxi drivers is representative of the population. It is assumed that the sample was randomly selected and that the taxi drivers included in the study are a fair and unbiased representation of all taxi drivers in Greece.

Answer:

0.00000002

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

2 * 10¹⁴ * x = 4 * 10⁶

To find the value of x;

x = 4 * 10⁶/2 * 10¹⁴

x = 2 * 10^{-8}

Therefore, the value of 2 x 10¹⁴ is 0.00000002 times the value of 4 x 10⁶

Answer:

Part A:

Is there any correlation between the number of hours spent practicing and the score in the game? Justify your answer.

Yes, there appears to be a positive correlation between the number of hours spent practicing and the score in the game as seen in the scatter diagram. The pattern formed is a straight line that rises as one moves from 0 along the x axis.

Part B:

Write a function that best fits the data. (3 points)

y = 5 + 6x

Score in the game = 5 + 6*(Number of hours spent practicing)

Part C:

What does the slope and y-intercept of the plot indicate? (3 points)

slope = 6

When the number of hours spent practicing increases by by 1 hour, the score in a game is predicted to increase by an average of 6.

y-intercept = 5

Score in a game is predicted to be 5 when the Number of hours spent practicing is equal to 0.

[tex]\theta \approx 1.23^\circ[/tex]

Step-by-step explanation:

The expression has been given as:

[tex]tan(\theta) = \frac{50}{18}[/tex]

Required: Find [tex]\theta[/tex]

Simplify the fraction

[tex]tan(\theta) = 2.7778[/tex]

Take arc tan of both sides

[tex]\theta = tan^{-1}(2.7778)[/tex]

[tex]\theta \approx 1.23^\circ[/tex]

Answer:

1/12

Step-by-step explanation:

First we have to calculate the sample space i.e. The total number of outcomes,

(H represents heads, T represents Tails and Numericals represent the number on the die)

H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6

= 12 sample spaces

Ok now so what is the probability that the die lands on 4 and it pops up as heads. So when we see the total outcomes we see that such event has only one such outcome

The number of outcomes/Total number of outcome

So therfore we can represent it in fraction as

1 / 12

Answer:

12

Step-by-step explanation:

if each bar is cut into 3 pieces, then we multiply 4 by 3 to get 12.

After he cuts the 4 bars, there are 12 pieces Jacob have.

Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.

Jacob has 4 granola bars.

He cuts them into pieces that are 1/3 of a bar each.

After he cuts the 4 bars.

After he cuts the 4 bars, how many pieces Jacob has is determined in the following steps given below.

[tex]\rm = \dfrac{Total \ granola \ bars}{Cut \ pieces}\\\\= \dfrac{4}{\dfrac{1}{3}}\\\\=\dfrac{4}{0.33}\\\\= 12.12\\\\= 12 \ apporx[/tex]

Hence, After he cuts the 4 bars, there are 12 pieces does Jacob have.

Step-by-step explanation:

Answer:

A has 263 calories

B has 257 calories

Step-by-step explanation:

system of equations:

a + 2b = 777

2a + b = 783

I multiplied the first equation by -2 to eliminate the 'a' terms

  -2a - 4b = -1554

+ 2a  + b =    783

         -3b = -771

b = 257

solve for 'a'

a + 2(257) = 777

a + 514 = 777

a = 263
