To answer this question, we need to know the median and upper quartile of the data set. Once we have these values, we can determine what percentage of the data falls to the right of the median and to the left of the upper quartile.
Let's say the median of the data set is 50 and the upper quartile is 75. To find the percentage of measurements to the right of the median, we need to look at the data values that are greater than 50 and divide that number by the total number of measurements. Let's say there are 40 data values greater than 50 and a total of 100 measurements.

Then, the percentage of measurements to the right of the median would be:

(40/100) x 100% = 40%

To find the percentage of measurements to the left of the upper quartile, we need to look at the data values that are less than or equal to 75 and divide that number by the total number of measurements. Let's say there are 60 data values less than or equal to 75 and a total of 100 measurements. Then, the percentage of measurements to the left of the upper quartile would be:

(60/100) x 100% = 60%


Your answer:
1. 40% of the measurements lie to the right of the median.
2. 60% of the measurements lie to the left of the upper quartile (Q3).

With a credit card balance of $17,426, a minimum monthly payment of $461, and an interest rate of 15.5%, we need to calculate the number of years it will take to pay off the card without adding any additional debt.

To determine the time required to pay off the credit card, we consider the monthly payment and the interest rate. Each month, a portion of the payment goes towards reducing the balance, while the remaining balance accrues interest.

To calculate the time needed for repayment, we track the decreasing balance each month. First, we determine the interest accrued on the remaining balance by multiplying it by the monthly interest rate (15.5% divided by 12).

We continue making monthly payments until the remaining balance reaches zero. By dividing the initial balance by the monthly payment minus the portion allocated to interest, we obtain the number of months needed for repayment. Finally, we divide the result by 12 to convert it into years.

In this scenario, it will take approximately 3.81 years to pay off the credit card (17,426 / (461 - (17,426 * (15.5% / 12))) / 12).

Answer:

C) 26

Step-by-step explanation:

a + 32 + 85 = 180   {Sum of all angles of triangle}

a + 117 = 180

a = 180 - 117

a = 63

b = a   {Vertically opposite angles}

b = 63

91 + 63 + c = 180  {Angle sum property of triangle}

154 + c = 180

c = 180 - 154

c = 26

Step-by-step explanation:

so you first put the points on the graph and connect them with a slanted line.

Next, for your equation start of with y =

then, your going to find your slope, after you find it put it in front of x (slope x) (Ex; if the slope was 3 then it would look like this 3x)

finally you write + and the y intercept (at which point the line goes through the y axis)

the equation together should look like y = slope x + y intercept

To calculate the volume of a nickel in cubic millimeters, we need to determine its dimensions. A US nickel has a diameter of 21.21 mm and a thickness of 1.95 mm.

Thus, its volume can be calculated using the formula for the volume of a cylinder:

Volume = π x (diameter/2)^2 x thickness

Volume = π x (21.21/2)^2 x 1.95

Volume = 313.06 mm^3

b. To convert cubic millimeters to cubic inches, we need to divide by the conversion factor (1 inch = 25.4 millimeters)^3:

Volume in cubic inches = (313.06 mm^3) / (25.4 mm/in)^3

Volume in cubic inches = 0.0191 in^3

c. To determine if the nickels would fit inside either of the paper cylinders, we need to calculate the volume of each cylinder and compare it to the total volume of the nickels. Let's assume the cylinders have a height of 10 inches and diameters of 5 inches and 6 inches, respectively. Using the formula for the volume of a cylinder, we can calculate their volumes:

Volume of cylinder 1 = π x (5/2)^2 x 10 = 392.7 in^3

Volume of cylinder 2 = π x (6/2)^2 x 10 = 565.5 in^3

Now we can calculate the total volume of 10,000 nickels:

Total volume of nickels = (10,000 nickels) x (0.0191 in^3/nickel) = 191 in^3

Since the total volume of the nickels is less than the volume of either cylinder, all the nickels would fit inside either of the two paper cylinders.

The solutions to the equation are x = -1, x = -8, and x = 1/2.

The equation 4x³ + 32x² + 42x - 16 = 0 can be divided throuh by 2 as follows:

2x³ + 16x² + 21x - 8 = 0

We can test each of these possible roots by substituting them into the equation and seeing if we get 0. When we substitute -1, we get 0, so -1 is a root of the equation. We can then factor out (x + 1) from the equation to get:

(x + 1)(2x² + 15x - 8) = 0

We can then factor the quadratic 2x² + 15x - 8 by grouping to get:

(x + 8)(2x - 1) = 0

This gives us two more roots, x = -8 and x = 1/2.

Therefore, the solutions to the equation are x = -1, x = -8, and x = 1/2.

The relative rate of change of the function f(t) = ln(t² + 4) at t = 1 is 40%.

To find the relative rate of change of the function f(t) = ln(t² + 4) at t = 1, we need to find the derivative of the function and evaluate it at t = 1. Let's calculate it step by step.

Step 1: Find the derivative of f(t)

Using the chain rule, the derivative of ln(t² + 4) with respect to t is given by:

f'(t) = (1 / (t² + 4)) * (2t)

Step 2: Evaluate f'(t) at t = 1

Substitute t = 1 into the derivative:

f'(1) = (1 / (1² + 4)) * (2 * 1)

= (1 / 5) * 2

= 2 / 5

Step 3: Convert the relative rate of change to a percentage

To express the relative rate of change as a percentage, multiply the value by 100:

Relative rate of change = (2 / 5) * 100

= 40%

Answer: x=55/6 or 55 over 6

Step-by-step explanation: Step 1: Distribute:

- 350= 12(x+20)

- 350= 12x + 240

Step 2: Subtract 240 from both sides:

- 350-240= 12x+240-240

Step 3: Simplify:

Subtract the numbers: 350-240= 12x+240-240= 110=12x+240-240

Subtract again: 110=12x+240-240= 110=12x

Step 4: Divide both sides by the same factor:

110=12x= 110/12= 12x/12

Step 5: Simplify:

- Divide the numbers: 110/12=12x/12= x=55/6=12x/12

- Cancel terms that are in both the numerator and denominator: 55/6=12x/12= 55/6=x

- Move the variables to the left: 55/6=x = x=55/6

Answer: x=55/6 or 55 over 6

The probability of scoring above 400 is 0.79 or 79%.

The probability that a student who scored above 400 reviewed for the test is approximately 0.753 or 75.3%.

The events are,

A = Student spent at least five hours studying GMAT review guides.

B = Student scored above 400.

Probabilities are,

Probability of scoring above 400 given that the student spent at least five hours studying GMAT review guides

P(B|A) = 0.85

Probability of scoring above 400 given that the student did not spend at least five hours studying GMAT review guides.

P(B|A') = 0.65

Probability that a student spent at least five hours studying GMAT review guides.

P(A) = 0.70

a. Find the probability of scoring above 400,

find P(B), use the Law of Total Probability,

which states that the probability of an event can be calculated by considering all possible ways the event can occur.

P(B)

= P(B|A) × P(A) + P(B|A') × P(A')

= 0.85 × 0.70 + 0.65 × (1 - 0.70)

= 0.595 + 0.195

= 0.79

b. The probability that a student who scored above 400 reviewed for the test,

To find P(A|B),

Use Bayes' theorem, which relates the conditional probabilities of two events.

P(A|B)

= (P(B|A) × P(A)) / P(B)

= (0.85 × 0.70) / 0.79

= 0.595 / 0.79

= 0.753

Therefore, the probability of scoring above 400 is 0.79  and probability of a student who scored above 400 reviewed for test is  0.753 .

Evaluating the expression in x = -25 and y = 10 gives the value -25.

Here we have the expression:

x + y - 10

And we want to evaluate it in x = -25 and y = 10, this just means that we need to replace the variables in the expression by the correspondent numbers.

Doing that we get:

-25 + 10 - 10

Now we can just simplify this expression:

-25 + 10 - 10 = -25 + (10 - 10) = -25
