One might think it isn't rational because it isn't just one number repeating. But because it has a consistent number, it is rational.
admission to a certain university is determined by an entrance exam. the scores of this test are normally distributed with a mean of 400 and a standard deviation of 60. only students who score in the top 30% will be offered admission. april scores 425 on the test. choose the most accurate statement.
Only students who score in the top 30% will be offered admission - this statement is accurate.
What is the mean and standard deviation of the entrance exam?In insights, the standard deviation is a proportion of how much variety or scattering of a bunch of values. A low standard deviation shows that the qualities will generally be near the mean of the set, while an elevated expectation deviation demonstrates that the qualities are fanned out over a more extensive territory. The standard deviation can generally be determined considerably more effectively with a number cruncher, and this might be satisfactory in certain tests. On my adding machine, you go into the standard deviation mode. Consequently, the main distinction among change and standard deviation is the units. For instance, in the event that we took the hours of 50 individuals running a 100-meter race, we would catch their time like a flash. Standard deviation assumes a vital part in the realm of money. In finance standard deviation is a factual estimation, when it's applied to the yearly pace of return of a venture.

What is the shape of this distribution?
O A. Unimodal skewed
• B. Bimodal symmetric
• C. Unimodal symmetric
• D. Bimodal skewed
O E. Uniform
Answer: your answer would be unimodal skewed. This graph only has one maxima, thus it can't be bimodal. However, it's not symmetric, meaning that it is skewed
Hope this helps you
Step-by-step explanation:
The histogram is solved and it is uni-modal skewed
What is Histogram?A graph called a histogram is used to show the frequency distribution of a small number of data points for a single variable.
A histogram displays the frequency distribution of a set of continuous data. It is useful for visualizing the shape of the data distribution, such as whether it is symmetrical or skewed, and identifying any outliers or gaps in the data.
Given data ,
Let the histogram be represented as A
Now , the value of A is plotted on the graph
A. Unimodal skewed: This distribution has one peak (mode) and the tail of the distribution extends to one side. Depending on which side the tail is longer, it can be either positively skewed (tail extends to the right) or negatively skewed (tail extends to the left).
B. Bimodal symmetric: This distribution has two distinct peaks (modes) and is symmetric, meaning the left and right sides of the distribution are roughly mirror images of each other.
C. Unimodal symmetric: This distribution has one peak (mode) and is roughly symmetric, meaning the left and right sides of the distribution are roughly mirror images of each other.
D. Bimodal skewed: This distribution has two distinct peaks (modes) and the tail of the distribution extends to one side for each peak. Depending on which side each tail is longer, it can be either positively skewed (tail of one peak extends to the right and the other to the left) or negatively skewed (tail of one peak extends to the left and the other to the right).
E. Uniform: This distribution is flat and has roughly equal frequency for all values in the range of the dataset.
Hence , the histogram is unimodal skewed

O 1.6 m
O 25m
O 3.3 m
O
5.6 m
The height of the machine piston after 10 seconds is 2. 5m . Option B
How to determine the value
Given the function;
y = 4.4 sin (0.4x -1.7) +2.3,
Where;
x represents time in secondsy is the height of the machine pistonGiven x as 10 seconds
y = 4. 4 sin ( 0.4(10) - 1. 7) + 2. 3
y = 4. 4 sin ( 4 - 1. 7) + 2. 3
y = 4. 4 sin (2. 3) + 2. 3
y = 4. 4(0. 04013) + 2. 3

The length of a bacterial cell is about 5 x 10−6 m, and the length of an amoeba cell is about 3.5 x 10−4 m. how many times smaller is the bacterial cell than the amoeba cell? write the final answer in scientific notation with the correct number of significant digits. 1.4 x 101 7 x 101 143 x 101 7 x 103
The bacterial cell is about 7 × 10^(1) times smaller than the amoeba cell in scientific notations.
What are scientific notations?
Scientific notations are a way of representing either a very small or a very large number in the powers of 10. Scientific notations comprise digits from 1 to 9 with powers of 10.
Calculation of the amount by which a bacterial cell is smaller than the amoeba cell
Given the length of amoeba cell in scientific notations is 3.5 × 10^(- 4)
The length of a bacterial cell in scientific notations is 5 × 10^(- 6)
To obtain how small the bacterial cell is from the amoeba cell, we need to divide both the lengths i.e.
= 3.5 × 10^(- 4) / 5 × 10^(- 6)
= 0.7 × 10^(2)
= 7 × 10^(1)
Hence, the bacterial cell is about 7 × 10^(1) times smaller than the amoeba cell in scientific notations.

The total area of the shaded regions in fraction of the total area of the block is 3/8 as the common fraction.
What is common fraction?A common fraction, sometimes known as a common fraction, is a fraction with an integer numerator and denominator. A common fraction may be used to identify a portion of a larger whole or set.
What is the formula for calculating a common fraction?Multiply each component of a fraction by both the denominator of another fraction to find the common denominator. To calculate the common denominator of 1/3 + 2/5, multiply the 1 through 3 by 5 and the 2 and 5 by 3. You should obtain a total of 5/15 + 6/15. The fractions can then be calculated.
According to the given data:Let's divide each square across four equal sections, for a total of 16 sections..
Using symmetry, one of the four portions in the top left square is shaded, and the same is true for the bottom right square.
Furthermore, two of the four squares inside this top right and bottom left corners are darkened.
