seventh grade had sold 200 tickets. Which grade sold the greatest percent of tickets?

what the answer plz???

Answer:

Step-by-step explanation:

6x² - 6x - 72 = 0

Using. Completing the squares method.

6x²/6 - 6x/6 = 72/6

x² - x = 12

Take the coefficient of x, halve and square and add to both sides.

(1/2)² = 1/4

( x + 1/4)² = 12 + 1/4

(x + 1/4)² = 48 + 1 /4

(x + 1/4)² = 49/4

x + 1/2 = 7/2

x = 7/2 ±1/2

x = 4 or x = 3

Answer:

A

Step-by-step explanation:

D is wrong because there's no AAA, only SSS

C is wrong because AB isn't equal to PR

B is wrong because x+5 has to equal 8 because the sides are equal. if x = 8 it would be 12.

Answer: B

Step-by-step explanation:

The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.

We can first eliminate C, because the y-intercept of the graph is 1.

To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).

Slope = (y2 - y1) / (x2 - x1)  

           = (-3 - 5) / (1 - (-1))

          = (-3 - 5) / (1 + 1)

          = -8/2

          = -4

Plug in the slope and y-intercept, we get y = -4x + 1

The number of bacteria  in an egg salad that is left out at room temperature is 256 option D.

The bacteria would double 4 times in 2 hours, so the total number of bacteria in the egg salad would be 256.

So we have 4 bacteria after 2 hours we have,

4 x 4 x 4 x 4 = 256 bacteria.

Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring.

Probability is defined as the degree to which something is likely to occur. This is the fundamental probability theory, which is also utilised in probability distribution, in which you will learn about the possible results of a random experiment. To determine the likelihood of a particular event occurring, we must first determine the total number of alternative possibilities.

Research has shown that competent communicators achieve effectiveness by adjusting their behaviors to the person and situation (option e).

Effective communication involves being adaptable and responsive to the specific context, individual preferences, and the needs of the situation.

Competent communicators recognize that different people have different communication styles, preferences, and expectations. They understand the importance of tailoring their communication approach to effectively connect and engage with others.

This may involve using appropriate language, tone, non-verbal cues, and listening actively to understand the needs and perspectives of others.

By adapting their behaviors, competent communicators can build rapport, foster understanding, and promote effective communication exchanges. They are mindful of the social and cultural dynamics at play, and they strive to communicate in a way that is respectful, inclusive, and conducive to achieving mutual goals.

In summary, competent communicators understand that effective communication is not a one-size-fits-all approach. They adjust their behaviors to the person and situation, demonstrating flexibility and adaptability in order to enhance communication effectiveness.

Competent communicators achieve effectiveness mostly by adjusting their behaviors to suit the person they are communicating with and the situation they find themselves in. While other factors, like having a broad vocabulary or giving feedback, play a part in effective communication, the former is considered the most crucial.

Research suggests that competent communicators achieve effectiveness mostly through adjusting their behaviors depending on the person they are communicating with and the situation they are in. This is option e. of your question. Communicating effectively involves behaviors like active listening, understanding the other person's point of view, being able to express thoughts and ideas clearly, and being polite and respectful. While a broad vocabulary (option b.) can be useful, it is not as crucial as adapting your behavior to fit the situation. Moreover, giving feedback (option d.) is a part of effective communication but not the sole defining factor. Apologizing when offending others (option c.) is also important but it doesn't necessarily make one a competent communicator. Using the same type of behavior in various situations (option a.) might not always work, as different situations and individuals require different communication styles.

The probability that it lands heads at least once is 1.0720.

Probability is the measure of the likelihood of an event occurring. In this case, we are looking at the probability of a coin landing heads at least once after three tosses.

Let's denote the event of the coin landing heads on the first toss as event A, the event of the coin landing heads on the second toss as event B, and the event of the coin landing heads on the third toss as event C.

The probability of landing heads at least once is equal to the sum of the probabilities of each individual event occurring (A, B, or C) minus the probability of all three events occurring (A and B and C).

P(A or B or C) = P(A) + P(B) + P(C) - P(A and B and C)

Since the coin is unfair and has a probability of 0.4 of landing heads, P(A) = P(B) = P(C) = 0.4.

Using the formula for the probability of multiple events happening simultaneously, we find that P(A and B and C) = P(A) * P(B) * P(C) = 0.4 * 0.4 * 0.4 = 0.064.

Plugging in all the values, we get:

P(A or B or C) = 0.4 + 0.4 + 0.4 - 0.064 = 1.136 - 0.064 = 1.072

Rounding to four decimal places, the answer is 1.0720, which means that the probability of the coin landing heads at least once after three tosses is 1.0720.

The correct answer is c. Inferential Statistics.

Inferential statistics is the branch of statistics that allows for drawing conclusions about a population based on the information collected from a sample. When conducting research or surveys, it is often impractical or impossible to collect data from an entire population.

Instead, a representative sample is chosen, and inferential statistics are used to make inferences or predictions about the larger population. By analyzing the characteristics and patterns observed within the sample, inferential statistics enable researchers to make generalizations or draw conclusions about the population as a whole.

This process involves applying various statistical techniques, such as hypothesis testing and confidence intervals, to estimate population parameters and assess the reliability of the conclusions. Magnitude statistics, central tendency, and effect size are important concepts in statistics, but they do not specifically address the ability to draw population-level conclusions from sample data.

Magnitude statistics focuses on the size of the effect or relationship between variables, central tendency measures summarize the central values of a dataset, and effect size quantifies the strength of an effect or relationship.

To find the divisor (div) and the remainder (mod):

a) To find div and mod, we use the formula: a = m x div + mod.
For a=228 and m=119:
- div = floor(a/m) = floor(1.9244) = 1
- mod = a - m x div = 228 - 119 x 1 = 109
Therefore, div = 1 and mod = 109.

b) For a=9009 and m=223:
- div = floor(a/m) = floor(40.4469) = 40
- mod = a - m x div = 9009 - 223 x 40 = 49
Therefore, div = 40 and mod = 49.

c) For a=-10101 and m=333:
- div = floor(a/m) = floor(-30.3903) = -31
- mod = a - m x div = -10101 - 333 x (-31) = -18
Therefore, div = -31 and mod = -18.

d) For a=-765432 and m=38271:
- div = floor(a/m) = floor(-19.9885) = -20

c.) 30 degrees

Step-by-step explanation:

the sum of the angles of a triangle is 180 degrees

so if the third angle was x

then

x=180-(20+130)

x=180-150

x=30 degrees

The measure of third angle is 30 degree.

The total of a triangle's three internal angles is 180 degrees, as stated by the angle sum feature of a triangle. A closed shape with both inner and exterior angles, a triangle is created by three line segments.

Given:

Two angles are 20 and 130.

Using Angle sum property of triangle

<1 + <2 + <3 = 180

20+ 130 + <3= 180

150 + <3 = 180

<3 = 180- 150

<3 = 30

Hence, the third angle is 30 degree.

Answer:

\(\frac{13}{4}\) · \(\frac{15}{4}\)

Step-by-step explanation:

Focusing on the first fraction, in order to simplify it, you have to multiply the denominator by the whole number; 4 x 3 is 12. You add the product to the numerator, so 12 + 1 would be 13. Therefore, the first fraction simplified would be \(\frac{13}{4}\).

We can apply the same procedure to the next fraction, so 3 x 4 is 12, and 12 + 3 is 15. \(\frac{15}{4}\) would be your answer.

Hope this helps! :)
