A survey finds that 40% of students ride in a car to school. Eri would like to estimate the probability that if 3 students were randomly selected, only 1 rides in a car. To simulate this probability, she lets the numbers 0, 1, 2, and 3 represent a student who rides in a car to school and then 4, 5, 6, 7, 8, and 9 represent a student who does not ride in a car to school. She then has a computer randomly select 3 numbers. She repeats this process for 20 trials. The results of these trials are shown in the table. 468 380 120 220 553 945 935 607 473 490 074 981 692 518 408 954 943 389 594 569 Based on this simulation, what is the estimated probability that only 1 of 3 randomly selected students rides in a car to school? Enter your answer, as a decimal, in the box.

Answers

Answer 1

Your answer is going to be 0.60

Answer 2

Final answer:

The estimated probability that only 1 of 3 randomly selected students rides in a car to school is 0.4 or 40%.

Explanation:

The estimated probability that only 1 of 3 randomly selected students rides in a car to school can be calculated by dividing the number of trials where only 1 student rides in a car by the total number of trials. In this case, there were 8 trials where only 1 student rides in a car out of a total of 20 trials.

Therefore, the estimated probability is:

8 / 20 = 0.4

So, the estimated probability is 0.4 or 40%.

To find out whether n = 112 is a solution to the inequality, plug 112 for n into the inequality and simplify.

10 + n/28 > 14
10 + 112/28 > 14
10 + 4 > 14
14 > 14

This reads "fourteen is greater than fourteen," which is false.

n = 112 is NOT a solution to the inequality 10 + n/28 > 14.

Answers

1. We have to find the fifth term of f(n) = 7 - 4(n - 1).
That means x = 5. Substitute 5 into the equation for x.
f(n) = 7 - 4(5 - 1)
Subtract 5 - 1.
f(n) = 7 - 4(4)
Multiply 4 by 4.
f(n) = 7 - 16
Subtract 16 from 7.
f(n) = -9
The answer is D.

2. Since we have to find the first 4 terms, we have to solve for x = 1, 2, 3, & 4.
Multiply 1, 2, 3, and 4 by 6. We now have:
f(x) = 6 - 25 f(x) = 12 - 25 f(x) = 18 - 25 f(x) = 24 - 25
Subtract 25 from the first term: 6, 12, 18, and 24.
f(x) = -19 f(x) = -13 f(x) = -7 f(x) = -1
The answer is C.

3. Now, we have to find the first 3 terms of f(x) = 10(2)^x. So x is 1, 2, & 3.
Raise 2 to the powers of 1, 2, and 3. The equations are now:
f(x) = 10(2) f(x) = 10(4) f(x) = 10(8)
Then multiply 10 by the three terms: 2, 4, and 8.
f(x) = 20 f(x) = 40 f(x) = 80
The answer is A.

4. Find the 21st term of f(n) = 2 + 9(n - 1). Substitute 21 for n.
f(n) = 2 + 9(21 - 1)
Subtract 1 from 21.
f(n) = 2 + 9(20)
Multiply 9 by 20.
f(n) = 2 + 180
Add 2 to 180.
f(n) = 182
The answer is B.

5. Which sequence is described by f(n) = 2(3)^x-5.
This is the only one which I'm not sure how to solve. Since I don't know, I won't answer it because I don't want to give you the wrong answer to the question, sorry about that.

6. The ninth term in f(n) = 384(1/2)^n-1. Put 9 in for n & subtract 1 from 9.
f(n) = 384(1/2)^8
Raise 1/2 to the power of 8.
f(n) = 384(1/256)
Multiply 1/256 by 384.
f(n) = 384/256
Reduce the fraction & make it a mixed number.
f(n) = 1 1/2

Step-by-step explanation:

two triangles are similar, and the ratio of the lengths of each pair of corresponding sides is 2:1. which statement regarding the two triangles is NOT True?

A- Their corresponding angles have a ratio of 2:!
B- Their areas have a ratio of 4:1
C- Their perimeters have a ratio of 2:!
D- Their altitudes have a ratio of 2:!

Answers

Answer: The correct answer is A - Their corresponding angles have a ratio of 2:1.

In the case of similar figures, we have the same basic shape however it is just make larger or smaller. Since this is the case, all of the angles will remain the same.

Imagine different sizes of stop signs. They are all similar and all the angles are the same. Only the lengths of the sides change.

All statements are true. Ratio of corresponding angles, areas, perimeters, and altitudes is 2:1. No false statement exists.

To determine which statement regarding the two triangles is NOT true, let's analyze each option step by step.

Given:

- Two triangles are similar.

- The ratio of the lengths of each pair of corresponding sides is 2:1.

Let's denote the lengths of corresponding sides in the first triangle as [tex]$ a $[/tex], [tex]$ b $[/tex], and [tex]$ c $[/tex], and in the second triangle as [tex]$ 2a $[/tex], [tex]$ 2b $[/tex], and [tex]$ 2c $,[/tex] respectively.

A. Their corresponding angles have a ratio of 2:1.

- This statement is true because corresponding angles in similar triangles are congruent, so their ratios would indeed be 2:1.

B. Their areas have a ratio of 4:1.

- The area of a triangle is proportional to the square of the length of its sides. So if the ratio of the lengths of corresponding sides is 2:1, the ratio of their areas would be [tex]$ (2:1)^2 = 4:1 $[/tex]. Hence, this statement is also true.

C. Their perimeters have a ratio of 2:1.

- The perimeters of triangles are directly proportional to the lengths of their sides. Since the ratio of the lengths of corresponding sides is 2:1, the ratio of their perimeters would indeed be 2:1. So, this statement is also true.

D. Their altitudes have a ratio of 2:1.

- The ratio of the altitudes of two similar triangles is equal to the ratio of their corresponding sides. So, if the ratio of corresponding sides is 2:1, the ratio of their altitudes would also be 2:1. Therefore, this statement is true.

Since all the statements are true, the correct answer is NONE.

The correct expression that is equal to 5p is A. p + p + p + p + p. Let's break it down:

A. p + p + p + p + p adds the variable p five times, which by definition equals 5p.

B. 4p + 1 simplifies to 4p + 1, which is not equal to 5p because it includes an additional constant term.

C. p + 5 represents the variable p plus the number 5, which is not the same as multiplying p by 5.

D. p3 + p2 is a polynomial with different powers of p and does not simplify to 5p.

Therefore, option A is the correct answer.

Sally decided to look at new and used vans. Sally found a used van for $14000. A new van is $20000, so what percent of the price of a new van does Sally pay for a used van?

Answers

Final answer:

Sally pays 70% of the price of a new van for a used van, which is calculated by dividing the price of the used van by the price of the new van and multiplying by 100.

Explanation:

To determine what percent of the price of a new van Sally pays for a used van, we use the formula for percentage: (Part / Whole) × 100. In this case, the price of the used van ($14,000) is the part, and the price of the new van ($20,000) is the whole. Hence, the calculation will be ($14,000 / $20,000) × 100.

Performing the calculation, we get: (14,000 / 20,000) × 100 = 0.7 × 100 = 70%.

Therefore, Sally pays 70% of the price of a new van for a used van.

Hey !!

Hope it helps you :)

Let the base angles be x as both are equal in a isosceles triangle
Now, x+x+(x-40)=180. Since sum of angles of a triangle
2x+(2x-40)=180
2x+2x-40=180
4x=180+40
4x=220
x=220/4
x=55

Now,they asked us vertex angle which is 40 degrees less than sum of base angles
Therefore x+x-40=vertex angle
2x-40=vertex angle
2(55)-40=vertex angle
110-40=vertex angle
Vertex angle =70 degrees

Suppose you have to use right-triangle trigonometry to find the apothem of a regular polygon. Which is greater, the apothem or the radius of the polygon?

Answers

Final answer:

In a regular polygon, the apothem is the distance from the center to the midpoint of a side, whereas the radius is the distance from the center to a vertex. Because the radius is the hypotenuse in a right triangle formed within the polygon, as per the Pythagorean theorem, it is always longer than the apothem.

Explanation:

In the context of a regular polygon, the apothem is defined as the distance from the center of the polygon to the midpoint of any side. The radius, on the other hand, is defined as the distance from the center to any of the vertices. Since a regular polygon's sides and angles are equal, one can observe that its apothem is always smaller than its radius.

In order to illustrate this, consider a right triangle formed by the radius, the apothem, and half the length of a side. By using the Pythagorean theorem (a² + b² = c²), we know that the radius (or hypotenuse) is the longest side, and therefore greater than the apothem (one of the perpendicular sides).

Simply put, the radius is always greater than the apothem in a regular polygon.

The radius of a regular polygon is always greater than the apothem.

To determine if the apothem or the radius of a regular polygon is greater, we can use a right-triangle trigonometry approach. Here's a step-by-step explanation:

Consider a regular polygon with n sides inscribed in a circle. The circle's radius is r, and this radius is the hypotenuse of a right triangle formed by the radius, the apothem a, and half the length of one side of the polygon.The apothem is the perpendicular distance from the center of the polygon to the midpoint of one of its sides.Since the hypotenuse of a right triangle is always the longest side, the radius (r) is always greater than the apothem (a) according to the Pythagorean theorem.For example, in a regular hexagon, the radius is twice the apothem, clearly illustrating this relationship.

Therefore, in any regular polygon, the apothem is always less than the radius, as the hypotenuse (radius) is the longest side in the right triangle formed by the apothem and half the length of a side of the polygon.

A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minutes this month. Which inequality can be used to determine how many more minutes Tom can use this month without going over the 500-minute limit?

Answers

The answer is x + 230 ≤ 500

Answer:

x + 230 ≤ 500

Step-by-step explanation:

Given,

The time for which Tom used the phone = 230 minutes,

Let he further used the mobile for x minutes,

So, the total time for which he used the phone = ( x + 230 ) minutes,

According to the question,

For the extra minutes more than 500 minutes, the mobile phone carrier charges an extra fee,

Thus, if he wants to use the phone, without going over the 500-minute limit,

Then, the total time used by him ≤ 500 minutes,

⇒ x + 230 ≤ 500

Which is the required inequality.

Subtract 3 from both sides
2d = 0
Now replace the = sign with the < sign again.
2d < 0
Divide both sides by 2 to get your final answer.
d < 0
If you are ever uncertain with an answer to an inequality, the best thing to do is plug in a random number! (In this case, make sure the number is less than 0)
3 + (-1) < 3 - (-1)

(-1) is less than zero, and when plugged into the inequality the values of the left side is less than the value of the right side. This shows that d IS < 0.
