The median score of the sample size is actually 75, as it is the middle value of the sorted scores.

The median is a measure of central tendency, which gives us a better understanding of the data by telling us the middle value of a set of numbers. To calculate the median of a random sample of students, the scores must first be sorted in ascending order: 0, 50, 50, 70, 70, 80, 90, 90, 90, 100. Then, the middle value can be found. In this case, the middle value is the fifth out of the ten scores, which is 80. Therefore, the median score is 80. However, this statement is incorrect because the median is actually 75. This is because the fifth and sixth scores (80 and 90) are both middle values, and when there are two middle values, the median is found by taking the mean of the two numbers (80 + 90 = 170; 170 ÷ 2 = 85). Therefore, the median of this random sample size of students is 75.

Answer:

y-9 = -1/12(x-8)

Step-by-step explanation:

To write an equation of a line perpendicular to the graph of y = 12x-3 and passing through the point, we will follow the following steps.

The standard form of point-slope form of the equation of a line is  given as

y − y1 = m(x − x1),

m is the slope of the unknown line

(x1, y1) is a point on the line.

Step 1: We need to calculate the slope of the known line first,

Given y = 12x-3

from the equation, m = 12 on comparison.

Step 2: get the slope of the unknown line. since the line given is perpendicular to the line y = 12x - 3, the product of their slope will be -1 i.e Mm = -1

M = -1/m

M is the slope of the unknown line

M = -1/12

Step 3: We will substitute M = -1/12 and the point (8, 9) into the point-slope form of the equation of a line i.e y − y1 = M(x − x1),

M = -1/12, x1 = 8 and y1 = 9

y-9 = -1/12(x-8)

Jim will have to pay $795 out-of-pocket if he has an accident that costs $3,000 in medical expenses. Option b is correct.

Let’s calculate the amount Jim has to pay out-of-pocket. Jim has an accident that costs $3,000 in medical expenses, so the total cost is $3000.Jim’s health insurance policy has the following provisions:

Deductible = $300

Co-pay = $50

Coinsurance = 70/30

Since the coinsurance provision is 70/30, this means that Jim's insurance will pay 70% of the remaining expenses after deductibles and co-pays and Jim will pay the remaining 30%.

Thus, Jim will pay 30% of the remaining expenses after deductibles and co-pays. Out of the total $3000 medical expenses, Jim has to pay the first $300 (deductible).

The remaining amount is $3000 – $300 = $2700.

He has a copay of $50, thus reducing the remaining amount to $2650.

So, Jim has to pay 30% of $2650 which is equal to:

$2650 × 0.3 = $795

Therefore, Jim has to pay out-of-pocket $795. The correct option is option B.

For quadratic formulas when you foil the equation you can easily identify the root values by setting them equal to 0 and solving for X. Note that a quadratic is of 2 degree so you get 2 root values. Now, instead  of 2, you have 3.

So... they give you the zeros x=2 and x=-1, now add your own random x value.

(x-2)(x+1)(x+3)

Now you can foil it into a polynomial equation.

Answer:

To determine the speed, we can use the formula:

speed = distance / time

where distance is measured in feet and time is measured in minutes.

In this case, the distance is 264 feet and the time is 3 minutes. Plugging these values into the formula, we get:

speed = 264 feet / 3 minutes

simplifying, we get:

speed = 88 feet/minute

Therefore, the equipment is traveling at a speed of 88 feet per minute.

Answer:

14.95

Step-by-step explanation:

a firm in a purely competitive industry is currently producing 1,000 units per day at a total cost of $700 then average total cost is $ 0.61

The average total cost is calculated as the total cost divided by the number of outputs. The firm's ATC at these three levels of production will be:

1. 1,000 units per day at a total cost of $700.

ATC = Total cost/output

ATC = $700/1000

ATC = $0.58

2. If the firm produced 500 units per day, its total cost would be $450.

ATC = Total cost/output

ATC = $450/500

ATC = $0.45

3. If it produced 700 units per day, its total cost would be $425.

ATC = Total cost/output

ATC = $425/700

ATC = $0.61

Answer:

1/4

unsimplified = 2/8

Step-by-step explanation:

2/8 is your answer because

you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.

So hence, your answer is 1/4

Step-by-step explanation:

From inspection of the box plot:

The left whisker (min value) to Q1 represents the bottom 25% of the data

Q1 to Q2 represents the second 25% of the data

Q2 to Q3 represents the third 25% of the data

Q3 to the right whisker (max value) represents the top 25%

Therefore, the sales of over $225 represent the top 25% of the data.  

25% represented as a fraction is 25/100 = 1/4

The required amount of money she earned after 4 years is Amount = 600(1 + 0.024 )⁴. Option 3 is correct.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Amount = principal[1 + r/n]ⁿᵃ

Principal  P = $600
rate  r = 2.4%  
Time = 4
n = 1

Now,
Amount = 600(1 + 0.024 )⁴

Given Angle A measuring 218.34 degrees, we want to find an angle between 0 and 360 degrees that has the same cosine as Angle A.

The cosine function is periodic with a period of 360 degrees. This means that angles that differ by multiples of 360 degrees will have the same cosine value. Therefore, to find an angle with the same cosine as Angle A, we can add or subtract multiples of 360 degrees from Angle A.

Since Angle A is already within the range of 0 to 360 degrees, we can directly state that Angle A has the same cosine as itself. Thus, Angle A (218.34 degrees) has the same cosine as Angle A (218.34 degrees).

Therefore, the angle between 0 and 360 degrees with the same cosine as Angle A is Angle A itself, which measures 218.34 degrees.

Answer:

1072.3 cm³ (1 dp)

Step-by-step explanation:

A hemisphere is half a sphere.

Therefore, calculate the volume of a sphere with radius 8 cm, then half it.

Volume of a sphere = 4/3 π 8³

                                  = 4/3 × π × 512

                                  = 2048/3 π cm³

Volume of hemisphere = (2048/3 π) ÷ 2

                                       = 1024/3 π

Answer: To get another turn, Sydney's score must be greater than 1. Therefore, to find the lowest number that Sydney can roll to get another turn, we need to find the smallest number that, when multiplied by the fraction on the card, will give a result greater than 1.

It's not mentioned which fraction card Sydney drew, so we can assume any fraction.

Let's assume the fraction card is labeled 1/4.

To get another turn, Sydney's score must be greater than 1. Therefore, we need to find the smallest number that, when multiplied by 1/4, will give a result greater than 1.

1/4 * x >1

x > 4

so the smallest number that Sydney can roll to get another turn is 5.

It should be noted that this is assuming that the fraction card is labeled 1/4 , if the fraction card is labeled with any other fraction the answer would be different.
