Answer: 64%

Step-by-step explanation:

The score you have entered means that the individual who took the test is at the sixty-fourth percentile – their percentile rank is 64%. This means that the student had a test score greater than or equal to 64% of the reference population. Conversely, 36% of students scored equal to or higher than the individual tested.

========================================================

Explanation:

The order matters because the jobs are different. This means we'll use a permutation.

We have n = 9 workers to pick from and r = 6 jobs to fill.

Plug those values into the nPr permutation formula.

[tex]n P r = \frac{n!}{ (n-r)! }\\\\9 P 6 = \frac{9!}{ (9-6)! }\\\\9 P 6 = \frac{9!}{ 3! }\\\\9 P 6 = \frac{9*8*7*6*5*4*3*2*1}{ 3*2*1 }\\\\9 P 6 = 9*8*7*6*5*4 \ \ \text{.... Note: The 3*2*1 cancels}\\\\9 P 6 = 60480\\\\[/tex]

There are 60480 ways to assign the 9 workers to the 6 different jobs where order matters.

----------------------

Another approach:

Label the 6 jobs as A,B,C,D,E,F

For job A, we have 9 workers to pick from.

For job B, we have 8 workers to pick from. This is because it states that there is "no more than one job to a worker".

For job C, we have 7 workers to pick from. And so on. We have this countdown going on. We stop once we reach job F.

We end up with 9*8*7*6*5*4 = 60480 different permutations

The string "9*8*7*6*5*4" is found in the second to last step of the section above.

The unique triangles that can be formed with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters is[tex]9.[/tex]

A triangle  can be referred to as a polygon with three edges and three vertices.

we can arrange length of one side of a unique triangle in 3 different ways.

Let x,y,z be the length of the three sides.

For triangles to be unique, length of one side can be arranged in 3 different ways.

Then, length of 6.5 cm can be at maximum three positions which is x,y,z.

The 2.5 cm lenght can appear to be at maximum three positions which is  x,y,z.This can as well be done for 6cm.

Answer:

14 times.

Step-by-step explanation:

It is how many times 1/4 go in 3 1/2.

3 1/2 as an improper fraction is 7/2.

To make them have the same denominator, we have to change 7/2.

7 x 2 = 14

2 x 2 = 4

So, how many times does 1/4 go in 14/4?

14 times.

The interval of times which represents the middle 68% of Ryan's finishing times in the 400 meter race, using the empirical rule, is 74.5 seconds to 75.5 seconds.

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here we had  where mean of distribution of X is [tex]\mu[/tex]  and standard deviation from mean of distribution of X is [tex]\sigma[/tex].

When Ryan runs the 400 meter dash, his finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 0.5 seconds.

The interval of times that represents the middle 68% of his finishing times in the 400 meter race is,

[tex]P(75 - 0.5 < X < 75 + 0.5) = 68\%\\P(74.5 < X < 75.5) = 68\%[/tex]

Thus. the interval of times which represents the middle 68% of Ryan's finishing times in the 400 meter race, using the empirical rule, is 74.5 seconds to 75.5 seconds.

Based on the calculations, the chemical element (X) in this nuclear equation is equal to ²³⁵U₉₂.

An alpha decay refers to a type of nuclear reaction in which the atomic nucleus of a radioactive element emits an alpha particle (atom of helium), thereby, producing chemical elements with a different atomic nucleus.

In this exercise, we are given the following nuclear equation with an alpha decay:

²³⁹Pu₉₄  -----> X + ⁴He₂

For the superscript, we have:

239 - 4 = 235.

For the subscript, we have:

94 - 2 = 92.

Answer:

1/6

Step-by-step explanation:

To simplify the expression:

      1. Change the divisor into it's reciprocal

     2. Change the sign into a multiplication sign.

     3. Evaluate the product of those fractions.

     4. Simplify the fraction. (If possible)

Given expression:

[tex]\dfrac{1}{6^3 } \div \dfrac{1}{36}[/tex]

According to step 1, we need to convert the divisor of the expression into it's reciprocal.

[tex]\dfrac{1}{6^3 } \div \dfrac{36}{1}[/tex]

According to step 2, we need to change the division sign (÷) into a multiplication sign (×).

[tex]\implies \dfrac{1}{6^3 } \times \dfrac{36}{1}[/tex]

According to step 3, we need to determine the product of these fractions. This can be done by evaluating the exponent.

[tex]\implies \dfrac{1}{(6)(6)(6) } \times \dfrac{36}{1}[/tex]

[tex]\implies \dfrac{1}{216 } \times \dfrac{36}{1}[/tex]

Multiply the fractions as needed. [a/b × c/d = (a × c)/(b × d) = (ac)/(bd):

[tex]\implies \dfrac{36}{216 }[/tex]

According to step 4, (If possible), Simplify the product of 1/216 and 36. In this case, the product of 1/216 and 36 is 36/216. Since both are divisible by 6, we can divide the numerator and the denominator by 6 to simplify the fraction.

[tex]\implies \dfrac{36 \div 6}{216 \div 6 }[/tex]

[tex]\implies \dfrac{1}{6 }[/tex]

Therefore, the quotient of 1/6^3 and 1/36 is 1/6.
