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

Your answer is going to be 0.60 
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%.

Part A
The scale is found by dividing the total actual distance by the measured distance.

Actual distance = 24 miles
Measured distance = 4 1/2 inches

Scale = 24 / 4 1/2
Scale = 24 / 4.5

The scale generally written as 1 unit on the map : whatever the distance is in miles or km.

Scale = 1 inch on the map : 5 1/3 miles
1:5 1/3 is normally the way the ratio is written.

Part B
You need a proportion for this
1/4 inch = 1 mile
x = 24 miles

Cross multiply
x = 1/4 * 24
x = 6 inches.

x = 6 inches.There are 24 1/4s in 6 inches.

Consider a 15-year mortgage at an interest rate of 8% compounded monthly. The amount to be mortgaged is $130,000. After the first month's payment, what is the new outstanding principal?

Answers

The answer is $129,624.32
Final answer:

To find the new outstanding principal after the first month's payment on a 15-year mortgage at an 8% interest rate compounded monthly, we calculate the monthly interest and subtract it from the original principal.

Explanation:

To find the new outstanding principal after the first month's payment, we need to calculate the monthly interest and subtract it from the original principal. Here are the steps:

Convert the annual interest rate to a monthly rate by dividing it by 12: 8% / 12 = 0.67%.Convert the mortgage amount to a decimal: $130,000Calculate the interest for one month: $130,000 × 0.67% = $871.67Subtract the interest from the original principal: $130,000 - $871.67 = $129,128.33

Therefore, the new outstanding principal after the first month's payment is $129,128.33.

vince begin practicing up on a piano at 5:15 p.m. he stopped playing at 5:35 p.m. how many degrees did the minute hand turn during vince's
practice time explain how you found your answer.

Answers

The minute hand turned 120 defrees.

For every 5 minutes, minute hand will turn 30 degrees as it takes 12 times 5 minutes to complete one round (one hr), which is 360 degrees. For Every 15 minutes, it turns 90 defrees.

So from 5.15 to 5.35pm, the minute had turned 20 minutes, that is 4 times of 5 minutes.

4 times of 5 minutes is equal to 4 times of 30 degrees, since it turns 30 degress for every 5 minutes.

So it has turned 120 degrees to move from 5.15 pm to 5.35 pm
Since you must turn 360 degrees to get around a full hour (60 minutes) we know that 10 minutes = 60 degrees of change because 360 / 6 = 60. Vince played piano for 20 minutes (5:15 - 5:35), and 2 x 10 = 20, so to ensure the equation 10 (minutes) = 60 (degrees) stays equivalent, we'll multiply 60 by 2 too. 60 x 2 = 120, so the minute hand turned 120 degrees during Vince's practice time.

The perimeter of a rectangle is 141 feet, and the length is twice the width. What are the dimensions of the rectangle?

What's the width of the rectangle and what's the length?

Answers

Final answer:

To find the width and length of the rectangle, we used the perimeter formula and the given relationship between length and width. The width of the rectangle is 23.5 feet and the length is 47 feet, which are found by dividing the perimeter by the sum of the multipliers of width and then multiplying the width by 2 to find the length.

Explanation:

The student asked for help with finding the dimensions of a rectangle given its perimeter and a relationship between its length and width. To find the dimensions of the rectangle, we can use algebra.

Firstly, we know the formula for the perimeter (P) of a rectangle is P = 2l + 2w, where l is the length and w is the width. Since we are given that the perimeter is 141 feet and the length is twice the width (l = 2w), we can set up the following equation:

141 = 2(2w) + 2w

Simplifying the equation, we get:

141 = 4w + 2w
141 = 6w
w = 141 / 6
w = 23.5 feet

Since the length is twice the width, the length (l) is:

l = 2 × 23.5 feet
l = 47 feet

Therefore, the dimensions of the rectangle are a width of 23.5 feet and a length of 47 feet.

Answers

Answer:

It's 79 I took the test

Stay Alive ~ T∅P I-/

Step-by-step explanation:

Answer:

The measure of [tex]m{\angle}b[/tex] is [tex]79^{\circ}[/tex].

Step-by-step explanation:

Given: Lines a and b are parallel to each other.

To find: The measure of the angle b.

Solution: It is given that  Lines a and b are parallel to each other, thus using the parallel lines properties, we have

[tex]m{\angle}a=79^{\circ}[/tex] (Vertically opposite angles)

Now, [tex]m{\angle}a[/tex] and [tex]m{\angle}b[/tex] forms the corresponding angle pair, thus they are congruent.

Hence, [tex]m{\angle}a[/tex]=[tex]m{\angle}b[/tex]=[tex]79^{\circ}[/tex].

Therefore, the measure of [tex]m{\angle}b[/tex] is [tex]79^{\circ}[/tex].

The equation of the circle in standard form is represented by the expression x² + y² = 2.

How to analyze a geometric locus

Geometric loci are point sets that represents a figure. A circle is a case of geometric locus. In this question we must determine the coordinates of the two points contained in the circumference and derive a circle equation in standard form.

Now we proceed to solve the following system of linear equations:

p = 4   (1)

a = 1   (2)

Then, the ends of the diameter are (3, 4) and (1, 2) and the radius of the circle is found by the following Pythagorean expression:

[tex]r = \frac{1}{2}\cdot \sqrt{(1-3)^{2}+(2-4)^{2}}[/tex]

Two consecutive odd numbers are such that seven times the smaller, subtracted from nine times the bigger, gives 144. Find the numbers.

Answers

Let
x-------------> first odd number 
x+2----------> second consecutive odd number

we know that
seven times the smaller, subtracted from nine times the bigger, gives 144

then
9*(x+2)-7*x=144-----------> 9x+18-7x=144---------> 2x=126-----> x=63

the numbers are
63 and 65

The smaller odd number is 63, and the next consecutive odd number is 65.

To find the consecutive odd numbers, an algebraic equation is set up and solved, yielding the smaller odd number as 63 and the next consecutive odd number as 65.

To find two consecutive odd numbers meeting the stipulated condition, we will set up an algebraic equation. Let the smaller odd number be represented by n, then the next consecutive odd number is n + 2. The given condition is that seven times the smaller odd number subtracted from nine times the bigger odd number equals 144. This can be expressed as the equation 9(n + 2) - 7n = 144.

Solving the equation:

Expand the equation: 9n + 18 - 7n = 144Combine like terms: 2n + 18 = 144Subtract 18 from both sides: 2n = 126Divide both sides by 2: n = 63

Therefore, the smaller odd number is 63, and the next consecutive odd number is 65.
