Answer:

**Answer:**

(a) The first quartile is 382.27 and it means that at least el 25% of the scores are less than 382.27 points.

The second quartile is 462 and it means that at least el 50% of the scores are less than 462 points.

The third quartile is 541.73 and it means that at least el 75% of the scores are less than 541.73 points.

(b) The 99th percentile is 739.27 and it means that at least el 99% of the scores are less than 739.27 points.

**Step-by-step explanation:**

The first, second the third quartile are the values that let a probability of 0.25, 0.5 and 0.75 on the left tail respectively.

So, to find the first quartile, we need to find the z-score for which:

P(Z<z) = 0.25

using the normal table, z is equal to: -0.67

So, the value x equal to the first quartile is:

Then, the first quartile is 382.27 and it means that at least el 25% of the scores are less than 382.27 points.

At the same way, the z-score for the second quartile is 0, so:

So, the second quartile is 462 and it means that at least el 50% of the scores are less than 462 points.

Finally, the z-score for the third quartile is 0.67, so:

So, the third quartile is 541.73 and it means that at least el 75% of the scores are less than 541.73 points.

Additionally, the z-score for the 99th percentile is the z-score for which:

P(Z<z) = 0.99

z = 2.33

So, the 99th percentile is calculated as:

So, the 99th percentile is 739.27 and it means that at least el 99% of the scores are less than 739.27 points.

**Answer:**

the probability that he length of this component is between 4.98 and 5.02 cm is 0.682 (68.2%)

**Step-by-step explanation:**

Since the random variable X= length of component chosen at random , is normally distributed, we can define the following standardized normal variable Z:

Z= (X- μ)/σ

where μ= mean of X , σ= standard deviation of X

for a length between 4.98 cm and 5.02 cm , then

Z₁= (X₁- μ)/σ = (4.98 cm - 5 cm)/0.02 cm = -1

Z₂= (X₂- μ)/σ = (5.02 cm - 5 cm)/0.02 cm = 1

therefore the probability that the length is between 4.98 cm and 5.02 cm is

P( 4.98 cm ≤X≤5.02 cm)=P( -1 ≤Z≤ 1) = P(Z≤1) - P(Z≤-1)

from standard normal distribution tables we find that

P( 4.98 cm ≤X≤5.02 cm) = P(Z≤1) - P(Z≤-1) = 0.841 - 0.159 = 0.682 (68.2%)

therefore the probability that he length of this component is between 4.98 and 5.02 cm is 0.682 (68.2%)

**Answer:**

**Step-by-step explanation:**

__Linear function of:__

- 14 HCF = $32.68
- 52 HCF = $95.38

__To find:__

- 19 HCF = ?

__Linear equation in slope-intercept form:__

- y(x) = mx +b

__We have points of: (14, 32.68), (52, 95.38):__

- y(14) = 14 m + b
- y(52) = 52 m +b

__Using the points we can find the value of m and b:__

- m= (y2-y1)/(x2-x1)
- m= (95.38 - 32.68)/(52 - 14)
- m = 62.7/ 28
- m= 1.65

__Then finding b:__

- 14*1.65 +b = 32.68
- b= 32.68 - 23.1
- b= 9.58

__So the function is:__

- y = 1.65 x + 9.58

__Then y(19) is found as:__

- y(19) = 1.65*19 + 9.58
- y(19) = 40.93

__Answer:__ Cost of 19 HCF of water is $40.93

Answer:

I would say it would be D

Step-by-step explanation:

Answer:the answer is d hope this helped

Step-by-step explanation:

Use one of the equations of motion under constant acceleration:-

s = ut + 0.5at^2 where s = distance, u - initial velocity, a = acceleration ( in this case it is gravity = 9.81 m s^-2) and t = time.

here we have s = 25*2 + 0.5*9.81 * 2^2

= 69.62 meters answer

**Answer:**** The height of the building is 69.6 m**

**Explanation:**

**To calculate the height of the building, we use second equation of motion:**

where,

s = height of the building = ?

u = initial velocity of the ball = 25 m/s

a = acceleration due to gravity =

t = time taken = 2.0 sec

**Putting values in above equation, we get:**

**Hence, the height of the building is 69.6 m**
