Answer 2

The 45th percentile of the data given above (P₄₅) is 16.225.

What is percentile in statistics?

Percentile refers to the mathematical or statistical term that is used to indicate the position of a data in relation to others from the sample given.

How did we arrive at the above figure?

Step 1 - First all data must be arranged in ascending order:

See the attached table for this.

Step 2 - We compute the position or rank of the 45th percentile.

The formula for percentile position is given as:

((n +1 ) *P)/100

= ((25+1) * 45)/100

= 11.70

Step 3 - Deploy the interpolation method because the position above is not an integer.

The numbers in positions 11 and 12 are where you'll find the 45 percent percentile. Based on the data arranged in ascending order, the values are 15 and 16.75.

The percentile we're seeking for is situated at the value of 11.7 - 11 = 0.7, which is the percentage of the space between 15 and 16.75.

Therefore,

(P₄₅) = 15 + 0.7 x (16.75 - 15)

(P₄₅) =16.225.

Probability helps us to know the chances of an event occurring. The probability that a worker will pick a bolt that is not defective is 5263/5265.

What is Probability?

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given the company has determined that 3 out of every 5265 bolts that it ordered is defective. Therefore, the probability that a worker will pick a bolt that is not defective is,

Probability = (Number of not defective bolts)/(Total number of bolts)

= (5265-3)/5265

= 5263/5565

Hence, the probability that a worker will pick a bolt that is not defective is 5263/5265.

Please Help, I am stuck on this question.

Answers

Answer:

(15/17 = sin ∠ JLK)

(first option listed)

Explanation:

the "sin ∠ JLK" is what we can simply think of as the inside measurement of angle/corner L. (L is the letter in the middle of ∠ JLK , and if you imagine drawing a line from J to L to K, you would see that the only angle you formed both sides of is corner L)

so, we are looking for the sin of L.

(SOH CAH TOA)

we know that

sin = opposite / hypotenuse

However, we do not have the opposite value of this triangle yet.

-----

we can solve the length of the opposite side with the Pythagorean theorem:

 a² + b² = c²

 8² + b² = 17²

 64 + b² = 289

- 64           - 64

     b²  =   225

   √b² = √225

    b = 15

----

so, to solve for sin L,

(sin = opposite / hypotenuse)

we should divide the opposite (15) over the hypotenuse (17)

so, 15 / 17 = sin L

(15/17 = sin ∠ JLK)

What is the set of real solutions for |x| ^2 - |x| -2 = 0

Answers

The set of real solution for  |x| ^2 – |x| -2 = 0 is x=-2 or x=2.

What is the real solution?

There are two real solutions for x if the discriminant's value is positive, which means that the graph of the solution has two distinct x-intercepts. This is called as the real solution.

Computation:

|x| ^2 – |x| -2 = 0

This can also be written as (|x| +1)(|x| -2)

then,

(|x| +1)(|x| -2) = 0

|x| +1 = 0 or |x| -2 = 0 (Using Zero factor principle)

Now, no solution for |x| +1 = 0 as x∈R

For |x| +2 = 0,

x = 2 or x = -2

Therefore, the solution for   |x| ^2—|x| -2 = 0 is x=-2 or x=2.
