Answer:

if i am right it yes yes no

Step-by-step explanation:

Answer:

Part A: \(\frac{3}{5}\)

Part B: \(\frac{1}{2}\)

Step-by-step explanation:

We know that Alinn flipped a coin 20 times, and that 12 of those times resulted in heads. The other 8 times resulted in tails.

Part A wants us to find the experimental probability of the coin landing on heads. Experimental probability is the probability determined based on the experiments performed.

Part B wants us to find the theoretical probability of the coin landing on heads. Theoretical probability is determined based on the number of favorable outcomes over the number of possible outcomes.

Experimental probability is determined as # of times something occurred experimentally / total number of times.  

Since 12 of the 20 times that Alinn flipped the coin resulted in heads, this means that the experimental probability of Alinn flipping heads is \(\frac{12}{20}\), which simplifies down to \(\frac{3}{5}\).

Theoretical probability, as stated above, is the number of favorable outcomes / possible outcomes.

Our favorable outcome is flipping heads, and on a coin, there are two sides that a coin can land on: heads and tails. This means that there are two possible outcomes, and only one of them is favorable.

This means that our theoretical probability is \(\frac{1}{2}\).

Answer:

x = 30

Step-by-step explanation:

110 and 3x - 20 are supplementary angles, sum to 180° , then

110 + 3x - 20 = 180

90 + 3x = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

Answer:

x = 30

Step-by-step explanation:

Please refer to the attached photo. (Apologies for the terrible drawing.)

For this question, you must be clear of the angle properties.

z + 110 = 180 (Sum of Angles on a straight line)

z = 180 - 110 = 70

z = 3x - 20 (Corresponding Angles)

3x - 20 = z

3x - 20 = 70

3x = 70 + 20

3x = 90

x = 90 / 3 = 30

Answer:

D, the lines coincide.

Step-by-step explanation:

isolate the y so theres no 2y, only y:

2y = 8 - 2x (divide both sides by 2)

y = 4 - x

The lines are the same line, so while they are plural, they also coincide, as one lies on top of the other.

Step-by-step explanation:

GL(2, Z) contains nonidentity elements of finite order (A and B) and an element of finite order (C) that is not the identity element.

One example of a group that contains nonidentity elements of finite order and of finite order is the group of 2x2 matrices with integer entries, denoted by GL(2, Z).

One non-identity element of finite order in this group is the matrix A = [1 1; 0 1], which has order 2. Another non-identity element of finite order is the matrix B = [-1 0; 0 -1], which has order 2 as well.

On the other hand, the matrix C = [0 1; -1 0] has finite order 4, since C^4 = I, where I is the identity matrix.

$35.20

Step-by-step explanation: 29.30+20%=35.20

Answer:

$35.16 Was the total amount spent at the restaurant.

Step-by-step explanation:

The first step is to change 20% to a decimal by moving the decimal point over twice.

20% → .20

Then, simply multiply .20 by 29.30.

.20 × 29.30 =  5.86

Okay, so- That was how to get the percentage for a number. Now, all you need to do is add 5.86 to the total bill to get the total amount spent. Like this:

29.30 + 5.86 = 35.16

Given the function:

Let's find the function after differentiating it 68 times.

To differentiate, let's take the derivative.

The point does not lie on the center of the circle.

The point (5, 11) does not lie on the circle centered at the origin and containing the point (2, 5√).

The center of the circle in question is the origin (0, 0). The point (2, 5√) lies on the circle, so we need to check if the distance between the origin and (5, 11) is equal to the radius.

To determine if a point lies on a circle, we can calculate the distance between the center of the circle and the given point. If the distance is equal to the radius of the circle, then the point lies on the circle.

The distance between two points in a coordinate plane can be calculated using the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Calculating the distance between the origin and (5, 11), we have:

d = sqrt((5 - 0)^2 + (11 - 0)^2) = sqrt(25 + 121) = sqrt(146)=12.083.

Since the distance, sqrt(146), is not equal to the radius of the circle, the point (5, 11) does not lie on the circle centered at the origin and containing the point (2, 5√).

The point of intersection for the system of linear inequalities y - 2x < 12 cannot be determined without additional information.

The given inequality, y - 2x < 12, represents a region in the coordinate plane. It is a half-plane below the line y = 2x + 12. However, since only one inequality is provided, we don't have enough information to pinpoint a specific point of intersection.

To determine the point of intersection for a system of linear inequalities, we would need another inequality or equation that defines a boundary or constraint. This additional equation or inequality would allow us to find the region of overlap between the two sets of solutions, leading to a point of intersection.

Without that additional information, we can only describe the region defined by the inequality y - 2x < 12. It is the area below the line y = 2x + 12 but does not provide a specific point of intersection.

Step-by-step explanation:

"congruent" in this simple form just means "equally large".

1. angles ISO and JSN, and angles JSO and NSI.

2. therefore, angle ISO = JSN = 113°

angle NSI is complementary to JSN (together they have 180°). NSI = 180 - JSN = 180 - 113 = 67°.

angle JSO = NSI = 67°.

3. yes and yes. they have to be. all inscribed triangles with the baseline being a circle diameter must be congruent. like NJO and NIO.

4. not sure what the yes/no options mean.

related to the angle congruence

arc IN is congruent to JO

arc NJ is congruent to IO

5. the arc angles are the same as the central angles. as this is the definition of the arc angles.

arc angle JO = angle JSO = 67°.

arc angle JN = angle JSN = 113°.

arc angle NI = angle NSI = 67°.

arc angle IO = angle ISO = 113°.

arc angle NJO = angle NO = 180°.

arc angle NIO = angle NO = 180°.

arc NJO is a half-circle.

arc NIO is a half-circle.

arc JNI is a half-circle.

arc JOI is a half-circle.

The probability that the student will fail, given that he guesses the answers, is 0.227.

Since there are only two possible outcomes for each question (true or false),

the probability of guessing a correct answer is 1/2 = 0.5.

Likewise, the probability of guessing a wrong answer is also 1/2 = 0.5.

To find the probability of failing the exam,

we need to find the probability of answering less than 11 questions correctly.

Using the binomial probability formula,

the probability of getting k successes (correct answers) in n trials (questions) is given by:

P(k) = (n C k) * p^k * q^(n-k)

where p is the probability of success (getting a correct answer),

q is the probability of failure (getting a wrong answer), and (n C k) is the number of combinations of n things taken k at a time.

In this case,

n = 17, p = 0.5, and

q = 0.5.

The number of ways to get less than 11 correct answers is:

P(X < 11) = P(X = 0) + P(X = 1) + ... + P(X = 10)P(X = k) = (n C k) * p^k * q^(n-k)

Substituting the values:

P(X < 11) = P(X = 0) + P(X = 1) + ... + P(X = 10)

P(X = 0) = (17 C 0) * (0.5)^0 * (0.5)^17 = 0.0015

P(X = 1) = (17 C 1) * (0.5)^1 * (0.5)^16 = 0.0146

P(X = 2) = (17 C 2) * (0.5)^2 * (0.5)^15 = 0.0586

P(X = 3) = (17 C 3) * (0.5)^3 * (0.5)^14 = 0.1558

P(X = 4) = (17 C 4) * (0.5)^4 * (0.5)^13 = 0.268

P(X = 5) = (17 C 5) * (0.5)^5 * (0.5)^12 = 0.327

P(X = 6) = (17 C 6) * (0.5)^6 * (0.5)^11 = 0.2732

P(X = 7) = (17 C 7) * (0.5)^7 * (0.5)^10 = 0.1537

P(X = 8) = (17 C 8) * (0.5)^8 * (0.5)^9 = 0.0573

P(X = 9) = (17 C 9) * (0.5)^9 * (0.5)^8 = 0.013

P(X = 10) = (17 C 10) * (0.5)^10 * (0.5)^7 = 0.0015

Therefore, P(X < 11) = 0.0015 + 0.0146 + 0.0586 + 0.1558 + 0.268 + 0.327 + 0.2732 + 0.1537 + 0.0573 + 0.013 + 0.0015P(X < 11) = 0.8857

Thus, the probability of failing is: P(fail) = P(X < 11) = 0.8857

Step-by-step explanation:

Therefore, Andrea has 25 dimes in 37 coins, all nickels and dimes and the value of the 37 coins is $3.10.

Let's represent the number of nickels by "n" and the number of dimes by "d".

From the problem, we know that:

n + d = 37 (equation 1) ---(the total number of coins)

0.05n + 0.1d = 3.10 (equation 2) ---(the total value of the coins in dollars)

To solve for d, we can rearrange equation 1 to get:

n = 37 - d

Substitute this expression for n into equation 2 and simplify:

0.05(37-d) + 0.1d = 3.10

1.85 - 0.05d + 0.1d = 3.10

The clock that shows the time Mr. Walsh left his house to go to the store would be 3:42 pm.

Mr. Walsh's journey consisted of driving from his house to the store, shopping for 28 minutes, and then driving back home. The total time for his journey would be:

10 minutes (driving to the store) + 28 minutes (shopping) + 10 minutes (driving back home) = 48 minutes

If Mr. Walsh arrived home at 4:30 pm, and we subtract the 48 minutes it took for his entire journey, we can determine the time he left his house to go to the store:

4:30 pm - 48 minutes = 3:42 pm

The experimental probability that the next menu slipped under Britney's door will be from a Chinese restaurant is 0.1 or 10%.

To find the experimental probability that the next menu slipped under Britney's door will be from a Chinese restaurant, we need to determine the number of Chinese restaurant menus in relation to the total number of menus.

The total number of menus is the sum of menus from all types of restaurants:

Total number of menus = Chinese + Japanese + Mediterranean + Thai + Italian

= 2 + 9 + 1 + 2 + 6

= 20

The number of Chinese restaurant menus is 2.
