Question

Destiny performs a hypothesis test on a population with Âµ = 115 and mc009-1.jpg. Her sample size is 25 with a mean of 120.4. Which of the following correctly depicts the z-statistic for this data?

Solution 1

Z-statistic is a statistical technique used to measure and the same time identify the position of a sample mean in the given population.Â

Statistics is a branch of mathematics which is the scientific study of mathematical values pertaining to qualitative descriptions and transcribe them into quantifying values such as the descriptive statistics and infuses these quantities in the field of inferential statistics.

Question

The time for a professor to grade a homework in statistics is normally distributed with a mean of 12.6 minutes and a standard deviation of 2.5 minutes. What is the probability that randomly selected homework will require more than 12 minutes to grade?

Solution 1

**Answer:**

59.48%

**Step-by-step explanation:**

To determine the probability you have to calculate the z score which is equivalent to the number of standard deviations you are from the mean.

x is the value you want to know its probability

Î¼ is the mean

Ïƒ is the standard deviation

A z score of -0.24 means you are 0.24 standard deviation at the left of the mean, the probability associated to a z of -0.24 can be found in a z table and it is 40.52%.

That probability cover the minimum value until 12 minutes, so the probability to need more than 12 minutes is 100 - 40.52 = 59.48%

Question

Suppose you randomly draw two cards from a standard deck of playing cards. What's the probability of drawing a four of clubs, and then drawing a seven of hearts? With Replacement:
Without Replacement:

Solution 1

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.Â

A) 13/52 * 12/51 = ?Â

B) 13/52 * 13/52 = ?

A) 13/52 * 12/51 = ?Â

B) 13/52 * 13/52 = ?

Question

Container a has 200 L and it's being filled at a rate of 6 liters per minute. Container b has 500 L of water, and is being drained at 6 Liters per minute how many minutes(m) will it take for the two containers to have the same amount of water

Solution 1

**Answer:**

**Step-by-step explanation:**

**Container A:** 200 L. Filled 6 liters per minute.

**Container B:** 500 L. Drained 6 liters per minute.

So, as you can see, filled means sum and drained mean subtract. Since that time is the magnitude we need to find, that will be are variable X.

Container A will have this expression: **200 + 6X**

Container B will have this expression: **500 - 6X**

*As you can see, six is multiplying the time, because it represents the velocity of the water (liters per minute).*

*Therefore, the question ask to calculate the time when containers are equal, so we do so with expressions:*

200 + 6X = 500 - 6X; Setting variables to the same site of the equality

6X + 6X = 500 - 200

12X = 300

This means that passed 25 minutes, containers will have the same amount of liters, let's check:

With a rate of 6 liters per minutes, after 25 minutes we'll have 6 x 25 = 150.

If we add 150 to the 200, and we subtract 150 from the 500, both are gonna result 350.

Question

What is the largest factor of 16 that is also a perfect cube?

Solution 1

The largest factor of 16 that is also a perfect cube is 2. When you factor out 16, you will get 4 times 4 and then factor out 4, you will also get 2 times 2 times 2 times 2. Other factors for 16 is 8 times 2 which can be further divided into 2 times 2 times 2 times 2. When you factor out 8, you get 2 times 2 times 2 and so 2 is a perfect cube.

Question

Choose the equation that represents a line that passes through points (-6, 4) and (2, 0). A. x + 2y =2
B. 2x - y = -16
C. x + 2y = -8
D. 2x + y = 4â€‹

Solution 1

**Answer:**

A.

**Step-by-step explanation:**

First, find the *rate of** **change** *[*slope*]:

Then use the **Slope-Intercept Formula** instead of the *Point-Slope** **Formula**,** *since you get it done faster this way. It does not matter which ordered pair you choose:

0 = âˆ’Â½[2] + b

** ****âˆ’1**

1 = b

y = âˆ’Â½x + 1

Then, convert to **Standard**** ****Form**:

y = âˆ’Â½x + 1

**+**** ****Â½x** **+ Â½x**

**________****_****_**

Â½x + y = 1 [We do **not** want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

**2**[Â½x + y = 1]

**__________________________________________________________**

4 = âˆ’Â½[âˆ’6] + b

**3**

1 = b

y = âˆ’Â½x + 1

Then, convert to **Standard Form**:

y = âˆ’Â½x + 1

**+ Â½x** **+ Â½x**

**________****_****_**

Â½x + y = 1 [We do **not** want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

**2**[Â½x + y = 1]

* You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.
