Answer:

The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.

Step-by-step explanation:

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.

Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits.

This means that [tex]\mu = 17, \sigma = 2.5[/tex]

What does the CLT say about the distribution of the sample mean of 49 students?

It is approximately normal.

The mean is 17.

Due to the sample of 49, n = 49, and the standard deviation is [tex]s = \frac{2.5}{\sqrt{49}} = 0.3571[/tex]

The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.

Answer:

y = 54

Step-by-step explanation:

Once again we are going to use the inscribed angle and intercepted arc relationship where the inscribed angle is equal to half of the measure of the intercepted arc.

Angle "y" is the inscribed angle and its intercepted arc has a measure of 108°

So y = one half of 108

[tex]\frac{108}{2} =54[/tex]

So we can conclude that y = 54

9514 1404 393

Answer:

  x = 8

Step-by-step explanation:

The measure of the inscribed angle is half the measure of the intercepted arc.

  9x -25 = 94/2

  9x = 72 . . . . . . . add 25

  x = 8 . . . . . . . . . divide by 9

The probability that a 6-digit locker combination, will be 1/180. Then the correct option is B.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The factor of n is given as the production of the number n, (n – 1), (n – 2)… and 1.

Then the factorial of n is given as

n! = n x (n – 1) x (n – 2) x … 3 x 2 x 1

A 6-digit locker that contains the digit will be 3, 5, 7, 3, 5, and 2.

Then the total number of combination without repetition will be given as,

Total events = 6! / (2! x 2!)

Total events = 6 x 5 x 4 x 3 x 2 x 1 / (2 x 1 x 2 x 1)

Total events = 6 x 5 x 3 x 2 x 1

Total events = 180

Then the favorable event will be

Favorable events = 1 {53-27-35]

Then the probability will be

P = (Favorable event) / (Total events)

P = 1/180

Then the correct option is B.

Amelia would have to multiply the number 7/10 on the price on the tags that she has to pay.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

The discount on new camera bought by Amelia = 30%.

To find the number that Amelia should multiply to pay,

Let The required number be x,

and total price of the camera is 100%

So after discount the price of camera = 100 - 30 = 70%

Implies that,

100 × x = 70

x = 70 / 100

x = 7 / 10

So the required number is 7/10 that Amelia should multiply the price she would have to pay.

I can't draw a picture for you! But I can give you the answer so maybe you can figure out a picture yourself. The answer is: 31

Step-by-step explanation:

If you have 84 total pencils and you know that 53 are regular pencils all you have to do is subtract 53 from 84. So you would do 84-53=31

So therefore 31 of the pencils are colored. Hope this helps!

Answer:

It costs Laura $ 5,184.86 to heat her house one day.

A 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

Step-by-step explanation:

Given that a kilowatt hour means 1 kilowatt of electricity used continuously for 1 hr, and the electric utility company in Laura's town charges $ 0.06001 for each kilowatt hour used, and Laura heats her house with three electric heaters that each use 1200 watts, to determine how much does it cost to heat a house in one day and how many hours would a 75 watt lightbulb have to stay on to result in one dollar for electricity charges the following calculations must be performed:

(3 x 1200 x 24) x 0.06001 = X

(3600 x 24) x 0.06001 = X

86400 x 0.06001 = X

5,184.86 = X

Therefore, it costs Laura $ 5,184.86 to heat her house one day.

1 watt = 0.001 kilowatt

75 watt = 0.075 kilowatt

1 / 0.075 = 13.333

1 / 0.06001 = 16,663

13,333 x 16,663 = 222.18

Therefore, a 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

The missing probabilities for Floral and Coconut are both 0.14.

To find the missing probabilities for Floral and Coconut, we need to consider that the sum of all probabilities must equal 1.

Let's calculate the missing probabilities:

The sum of the given probabilities is:

0.31 + 0.18 + 0.23 = 0.72

Since the sum of all probabilities must equal 1, we subtract the sum of the given probabilities from 1 to find the remaining probability:

1 - 0.72 = 0.28

Since the probability of Floral and Coconut is the same, we divide the remaining probability equally between the two scents:

0.28 / 2 = 0.14

Therefore, the missing probabilities for Floral and Coconut are both 0.14.

Answer:

1.2X = $

Step-by-step explanation:

Para construir una fórmula que permita calcular el dinero recaudado en un autobús en función de los billetes vendidos, sabiendo que cada uno cuesta 1,2 euros, se debe realizar el siguiente razonamiento lógico matemático:

1.2(variable fija) x X (número de billetes vendidos) = $ (Dinero recaudado)

1.2X = $

Por lo tanto, si por ejemplo se hubiesen vendido 100 billetes, la ecuación operaría de la siguiente manera:

1.2 x 100 = $

Answer:

Part 1: 375 Fuel Capacity

Part 2: 450 Fuel Capacity

Step-by-step explanation:

Find the percentage of each number with a calculator

375 fuel capacity does it have.

When decide to change the max to 600 new fuel capacity of the ship is 450.

Given that,

The max Fuel capacity a spaceship should have is 500.

The required 375 fuel capacity does it have.

When decide to change the max to 600 new fuel capacity of the ship is 450 determine,

How much fuel capacity does it have? If, in the above example, we decide to change the max to 600, what is the new fuel capacity of the ship.

According to the question,

The max Fuel capacity a spaceship should have is 500.

The ship you are designing is rated at 75% of range.

Full capacity is equals to max fuel capacity multiply by ship designing rate of range.

Therefore,

Fuel capacity = 500 × 0.75 = 375

And If the change in max fuel capacity to 600,

New fuel capacity is equals to new max fuel capacity multiply by ship designing rate of range.

Then.

New fuel capacity = 600 × 0.75 = 450

Hence, The required 375 fuel capacity does it have.

When decide to change the max to 600 new fuel capacity of the ship is 450.

Answer:

The recommended sample size is 1,698

Step-by-step explanation:

The given standard deviation in milk consumption per capita across the U.S., σ = 4 ounces

The required confidence level = 95%

The margin of error, e = ± 0.5

When the precision is doubled, we have the new margin of error = ±0.5/2 = ±0.25

The standard score at 99% confidence level, z = 2.576

The sample size formula is given as follows;

[tex]S = \dfrac{Z^2 \times P \times Q}{E^2}[/tex]

Where;

P × Q = The variance = σ²

∴ P × Q = 4² = 16

The sample size becomes;

S = 2.576² × 16/(0.25²) = 1,698.758656

We round down to get the recommended sample size, S = 1,698
