65 64 68 67 67

Find the percentile rank of 73. % =

Answers

Answer 1

Answer:

The percentile rank of the data value 73 is 84.

Step-by-step explanation:

In this problem, you want to find the percentile rank of the data value 73 in the data set.

The percentile rank represents the percent of numbers in the data set that have value equal or less than 73.

Take note that there are 25 data values in this data set. It's helpful to sort them in ascending order.

Of these 25 data values, 21 are less than or equal to the data value 73. To find the percentile rank of 73, apply the formula:

percentile rank = (L/N)(100)

where L is the number of data values that are less than or equal to 73, and N is the size of the data set.

Substituting in values for this problem, we have:

percentile rank = (21/25)(100)

percentile rank = (0.84)(100)

Percentile ranks are always expressed as whole numbers.

Evaluating the multiplication above and rounding to the nearest whole number we have:

percentile rank = 84

Interpreting our answer, 84% of the numbers in the data set have values less than or equal to 73.

explanation:

Isolate S on the left side by adding 1.9x to both sides. this gives you S = 4.8 + 1.9x. Plug in 22 for x because 2020 is 22 years from 1998.

4.8 + 1.9(22) = 46.6

Answer:

S=46.6

Step-by-step explanation:

x is the number of years :

from 1998 to 2020 = 22 years

S-1.9x=4.8

S-(1.9)(22)=4.8

S=4.8+41.8

S=46.6

5. Natalie has a pound bag of 1/8 pound bag of gummy worms, a 1/2 pound bag of twizzlers, and a 2/3 pound bag of chocolate. How many pounds of candy does Natalie have in all? ​

Answers

Step-by-step explanation:

1. Add all the different candies together

1/8 + 1/2 + 2/3=

2. Find the lowest common multiple of all the denominators

All the denominators can evenly multiply to 24 so 24 is the Lowest Common Denominator.

3. Multiply to make all the denominators 24

8x3=24 2x12=24 3x8=24

4. Whatever you did to the denominators, do the same thing to the numerators of that specific denominator.

1x3/8x3 1x12/2x12 2x8/3x8

5. Now that the denominators are the same for all the fractions, add all the numerators together.

3/24 + 12/24 + 16/24

3+12+16= 31

For an indirect proof, what must first be assumed to prove that LaTeX: \angle X∠ Xis a right angle?

Answers

Answer:

If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.

Step-by-step explanation:

An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.

                                     < X = right angle =  [tex]90^{o}[/tex]

A right angle is one that is equal to [tex]90^{o}[/tex]. As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.

Given: 2q – r = 4p, 2r = q, r = 2p; Prove: q = r

Answers

Answer:

q = r

Step-by-step explanation:

Explanation:-

Given    2q – r = 4p ...(i)

                  2r = q...(ii)

                  r = 2p ...(iii)

Substitute 2r = q in equation (i)

              2(2r) – r = 4p

                     3 r = 4 p

                   2 r + r = 4 p

                   2 r + 2 p = 4 p

                  2 r = 2 p

I can’t figure out how to find the average.

Answers

Answer:

The student needs a minimum score of 81 on the fourth test to ensure a grade of at least a C in the class.

Step-by-step explanation:

Remember what an average is. (Look at the hint at the bottom of the problem.)

To find the average of a set of numbers, add all the numbers and divide by the number of numbers.

For example, if in a class you took 8 tests, the average of the 8 tests is the sum of the 8 scores divided by 8.

In this case, the student took 3 tests and is taking one more, so in the end there will be 4 scores. The number of tests is 4.

We know 3 of the 4 scores. We don't know the fourth score because he has not taken the test yet, so we use a variable to represent the unknown score. Let's call the score of the fourth test x.

To find the average of the 4 scores, we add them and divide the sum by 4.

The three known scores are 63, 62, 74.

The unknown score is x.

Add all 4 scores: 63 + 62 + 74 + x.

Now we divide the sum of the 4 scores by 4 to find the average of the 4 scores.

[tex] \dfrac{63 + 62 + 74 + x}{4} [/tex]

The expression above is the average of the 4 scores. We want the average to be at least 70, so we need the average to be greater than or equal to 70.

We get this inequality.

[tex] \dfrac{63 + 62 + 74 + x}{4} \ge 70 [/tex]

Now we solve the inequality for x.

Add like terms in the numerator.

[tex] \dfrac{199 + x}{4} \ge 70 [/tex]

Multiply both sides by 4.

199 + x = 280

Subtract 199 from both sides.

x = 81

A basketball player makes 80% of his free throws. We set him on the free throw line and told him to shoot free throws until he misses. Let the random variable X be the number of free throws taken by the player until he misses. Assuming that his shots are independent, what is the probability of this player missing a free throw for the first time on the fifth attempt

Answers

Answer: 0.08192

Step-by-step explanation:

Given: Probability of free throws = 0.80

Then, probability of missing the free throw = 1-0.80=0.20

Now, According to the negative binomial probability distribution, the probability that the rth success is achieved in xth trial is given by ;-

[tex]P(X=x)= pC_{r-1}^{x-1}p^{r-1}(1-p)^{(x-r}[/tex]

Put p = 0.20 , x=5 and r =1, we get

The probability of this player missing a free throw for the first time on the fifth attempt as [tex](0.20)\ ^{5-1}C_{1-1}(0.20)^{1-1}(1-0.20)^{5-1}[/tex]

[tex]= (0.20)\ ^{4}C_{0}(0.20)^{0}(0.80)^{4}\\\\=(0.20)(1)(0.80)^4\\\\=(0.20)(0.4096)\\\\=0.08192[/tex]

hence the required probability =0.08192
