Answer:

0.3413 = 34.13% probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10.

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 z-score 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 p-value, 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.

Mean equals to $10 and a population standard deviation of $4

This means that [tex]\mu = 10, \sigma = 4[/tex]

Sample of 64

This means that [tex]n = 8, s = \frac{4}{\sqrt{64}} = 0.5[/tex]

What is the probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10?

This is the pvalue of Z when X = 10 subtracted by the pvalue of Z when X = 9.5.

X = 10

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

By the Central Limit Theorem

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

[tex]Z = \frac{10 - 10}{0.5}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a pvalue of 0.5

X = 9.5

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

[tex]Z = \frac{9.5 - 10}{0.5}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587

0.5 - 0.1587 = 0.3413

0.3413 = 34.13% probability that the sample mean fare of the 64 fares in the sample is between $9.5 and $10.

Answer:

$126720

Step-by-step explanation:

2nd hour tickets =120%

1st hour tickets =100%

100%=1280people

120%= ?

=1536 people+1280

=2816people were sold tickets

2816people are the same as 2816tickets

If 1 ticket =$45

2816tickets=?

2816*45=

=$126720

Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]x + 2y = 7[/tex]

Required

Draw the graph

First, we identify at least 2 possible values of x and y

Let [tex]x = 1[/tex]

Solve for y

[tex]x + 2y = 7[/tex]

[tex]1 + 2y = 7[/tex]

[tex]2y = 6[/tex]

[tex]y = 3[/tex]

So, a point is: [tex](1,3)[/tex]

Let [tex]x = 3[/tex]

Solve for y

[tex]x + 2y = 7[/tex]

[tex]3 + 2y = 7[/tex]

[tex]2y = 7 -3[/tex]

[tex]2y = 4[/tex]

[tex]y = 2[/tex]

So, another point is: [tex](3,2)[/tex]

Plot [tex](1,3)[/tex] and [tex](3,2)[/tex] on the graph, then draw a straight line through both points

Answer:

B and E

Step-by-step explanation:

perpendicular sides mean they will equal 90 degrees... so all rectangles and squares are perpendicular- a 90 degree triangle also is perpendicular. The Equatorial and the Acute triangle do not have 90 degree angles

Answer:

39.80°

Step-by-step explanation:

Find the diagram attached

Given the following

Opposite side = 5m

Adjacent = 6m

Required

Angle Ø

Using the SOH CAH TOA identity

Tan Ø = opposite/adjacent

Tan Ø  = 5/6

Tan Ø  = 0.8333

Ø = arctan(0.8333)

Ø = 39.80°

Hence the measure of the angle represented by Ø is 39.80°

Answer:

Option (1)

Step-by-step explanation:

Exponential equation that models the increase in the number of books has been given as,

[tex]B=8700e^{0.04t}[/tex]

Here, B = Number of books

t = Number of years

Number of books after t = 3,

[tex]B=8700\times e^{0.04\times 3}[/tex]

   [tex]=8700\times e^{0.12}[/tex]

   = 9809.226

   ≈ 9809

Therefore, Option (1) will be the correct option.

Answer:

After 3 years, the library will have approximately 9,809 books.

Step-by-step explanation:

If [tex]t[/tex] represents the number of years passed, in the time of 3 years, the library shall have [tex]8700e^{0.04*3} = 8700e^{0.12}[/tex] ≈ [tex]8700*1.12749[/tex] ≈ [tex]9,809[/tex] books.

Answer:

See explaination and answer below

Step-by-step explanation:

Absolute Error:

ae = | E - A |

ae = | 35ft - 33ft|

ae = 2 ft

Percent Error:

pe = 100% * | E - A | / A

pe = 100% * | 35ft - 33ft | / 33ft

pe = 6.06% error

EDIT: 6.1% if asked to the nearest tenth.

Answer:

the answer to the equation is x= -3

Answer:

boys = 272

Step-by-step explanation:

b = boys

g = girls

1) write two equations with the given informations:

g + b = 650

g = b + 106

2) substitute the value of g in the first equation:

b + 106 + b = 650

3) solve the equation for b

2b = 544

b = 272

4) substitute the value in the second equation

g = 272 + 106

g = 378

girls = 378

boys = 272

Answer: The median of the data is 34

Step-by-step explanation: the reason why it is 34 is because when your dealing with medians you want to put down the number that you see the most of for example you see 34 three times so the number you see the most is 34 so the answer is 34

I didn’t get the first part of the question that well but this is the answer for the question

Answer:

Ask the full question please it can't be understood

Answer:

Okay so we have to solve this in separate parts. Like so, its wiill go like this: 2+ 1/6 - 1 - 2/3. So we see that we have 2 and 1 as whole. Subtract 2 - 1 is 1 right. Now for fractional part 1/6 - 2/3. Since its uneven, we have to find the LCD which is 6. This forms of our fractions into 1/6- 4/6. 1/6 - 4/6 is 3/6. simplify it would result in 1/2.  The amount of ground chicken that Terrell has left is 1/2.
