In a large population, very close to 25% of the observations will fall below the 25th percentile (Q1), and close to 75% fall below the 75th percentile (Q3). The Web site of the Educational Testing Service reports that on the SAT Verbal test, with a possible perfect score of 800, the 89th percentile of 1,475,623 scores nationwide is a score of 670. What is the best estimate of exactly how many scores were below 670?

Answers

Answer 1

Solving:

.89 * 1,475,623 = 1,313,304.47

So, the answer would be:

In the year 2000, Franklintown had a population of 30,000 people. Its population had decreased by 3% each year since then. Part A: Can this situation be modeled by an exponential decay function, an exponential growth function, or neither? Explain. Part B: If the population continues to decrease at the same rate, what would you expect the approximate population to be in 2016? Show your work.

Answers

Part A:
For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time
Substituting values we have:
y = 30000 * (0.97) ^ t
Answer:
this situation can be modeled by an exponential decay function.

Part B:

We have the following function:
y = 30000 * (0.97) ^ t
For the year 2016 we have to:
t = 16
Substituting values:
y = 30000 * (0.97) ^ 16
y = 18427.6096
Rounding:
y = 18428
Answer:
The approximate population for 2016 is:

For this question we need to make a Venn Diagram as shown below.

Start from the inner most circle.

5 patrons like all 3 drinks.
8 patrons like Latte and Espresso. From these 8, 5 like all 3 drinks, so the patrons which only like Latte and Espresso will be 3.

Fill all the regions this way and you will get a diagram similar to the one given below.

Count all the numbers inside the circles. These add up to 47. This means 47 patrons like the drinks.

Total number of patrons was 50. So there are 7 such patrons which do not like any of these drinks.

So, the correct answer is option B

The center of the circle is at (-1, 1). The radius is determined by the distance from the center to the highlighted point (6, -4). The distance = sqrt[(6+1)^2 + (-4-1)^2] = sqrt[49 + 25] = sqrt(74)

You are traveling to Chicago for a job interview. You leave Toledo, Ohio, at 5:45 A.M. and arrive in Elkhart, Indiana, at 8:15 A.M.. The distance from Toledo to Elkhart is 136 miles; the distance from Toledo to Chicago is 244 miles. The speed limit is 65 mph. What is the minimum speed you must maintain in order to arrive in Chicago before 10:30 A.M.

Answers

To find the minimum speed need to reach Chicago based on this information, you will need to know how far it is from Elkhart to Toledo and how long it takes.

To get from Elkhart to Toledo is 108 miles. (244-136)

It will take 2.25 hours to get there. From 8:15 am to 10:30 am is 2 1/4 hours.

108 miles/2.25 hours = 48 miles per hour. You must travel at an average speed of 48 miles per hour.

Which summation formula represents the series below?

13 + 9 + 5 + 1

Answers

The sum of the series is 28.

The series 13 + 9 + 5 + 1 is an arithmetic series with a common difference of -4. To express this in summation (sigma) notation and find its sum, we first identify the first term (a1) as 13 and the common difference (d) as -4.

Next, we determine the number of terms (n). The series decreases by 4 each time, so we find the number of steps it takes to go from 13 to 1, which are 4 terms in total (13, 9, 5, 1).

We can write the summation formula for an arithmetic series as Sn = n/2 * (2a1 + (n-1)d), where Sn is the sum of the first n terms. With n = 4, a1 = 13, and d = -4, we plug these into the formula:

S4 = 4/2 * (2(13) + (4-1)(-4))

S4 = 2 * (26 - 12)

S4 = 2 * 14

S4 = 28

The sum of the series is 28.

a player gets to throw 4 darts at the target shown. Assuming the player will always hit the target, the probability of hitting an odd number three times is *blank* times more than the probability of hitting an even number 3 times

Answers

Answer: The probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.

Step-by-step explanation:

From the given picture , the total total number of sections in the spinner = 5

Sections having Odd numbers = 3

Sections having Even numbers =2

We know that , [tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

So , probability of hitting an odd number = [tex]\dfrac{3}{5}[/tex]

Probability of hitting an even number = [tex]\dfrac{2}{5}[/tex]

Since all events are independent of each other ,

So , probability of hitting an odd number three times = [tex](\dfrac{3}{5})^3=\dfrac{27}{125}[/tex]

Probability of hitting an even number three times = [tex](\dfrac{2}{5})^3=\dfrac{8}{125}[/tex]

Divide [tex]\dfrac{27}{125}[/tex] by [tex]\dfrac{8}{125}[/tex] , we get

[tex]\dfrac{27}{125}\div\dfrac{8}{125}\\\\=\dfrac{27}{125}\times\dfrac{125}{8}=\dfrac{27}{8}=3\dfrac{3}{8}[/tex]

Hence, the probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.

12+5v=2v-9 please show step by step!

Answers

12 + 5v = 2v - 9
Subtract 12 from both sides.

5v = 2v - 21
Subtract 2v from both sides.

3v = -21
Divide both sides by 3.

v = -7

To get it, combine like terms and restrain the variable. Segregating both sides by 3 gives the solution to the equation as v = -7.

How to solve the expression

To solve the condition 12 + 5v = 2v - 9, take after these steps:

Step 1: Segregate the variable terms on one side of the condition and the steady terms on the other side.

Subtract 2v from both sides to move the variable term to the cleared outside:

12 + 5v - 2v = 2v - 9 - 2v

Alter both sides of the condition:

12 + 3v = -9

Step 2: Separate the variable term by moving the reliable term to the other side.

Subtract 12 from both sides to move the dependable term to the proper side:

12 + 3v - 12 = -9 - 12

Unwind both sides of the condition:

3v = -21

Step 3: Light up for v by confining both sides of the condition by the coefficient of v, which is 3.

Portion by 3 to clarify for v:

v = -21 / 3

Streamline the division:

v = -7

The solution to the equation is v = -7.

The first 2 are false, the second 2 are both true. Because all the angles in a triangle have to add up to equal 180, then 40 + 52 + 88 = 180. Therefore, the combinations of 52 and 88 and 40 and 88 fit correctly. 92 doesn't fit at all. It's too big.
