The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with a mean of 149714971497 and standard deviation of 322322322. Let XXX represent the score of a randomly selected tester from this group. Find P(1497
The probability is 0.4444.
What is probability?Probability is a measure of the likelihood of a particular outcome occurring in a given situation. It is the chance that something will happen or is true. Probability is expressed as a number between 0 (impossible) and 1 (certain). Probability is a mathematical way of predicting what will happen in the future based on a given set of data. It is used to analyze the likelihood of various outcomes in a range of scenarios, such as gambling, finance, insurance, and weather forecasting.
The probability of a randomly selected tester from the group of college-bound seniors having a score between 1497 and 1507 can be calculated using the standard normal distribution. First, we need to convert the scores to standard scores, or z-scores. Subtract the mean from the scores and divide by the standard deviation to get z-scores.
For XXX = 1497, z = (1497 - 1497) / 322 = 0.
For XXX = 1507, z = (1507 - 1497) / 322 = 0.31.
Using a standard normal table, we can calculate the area under the normal curve between 0 and 0.31. The probability of randomly selecting a tester with a score between 1497 and 1507 is 0.4444. The probability is therefore P(1497 ≤ XXX ≤ 1507) = 0.4444.

which equation represents a line perpendicular to the given line x-4y=7
The equation of the line perpendicular to x - 4y = 7 can be written as:
y = 4*x + b
Where b could be any real number.
Which equation represents a line perpendicular to x - 4y = 7?Two lines are perpendicular if the product between the slopes of the lines is equal to -1.
Where a general line in the slope-intercept form is written as:
y =a*x +b
And the given line is:
x - 4y = 7
Writing this in the slope-intercept form we will get:
-4y = -x - 7
y = (-1/4)*x + 7/4
So the slope is -1/4, then the slope of our line must be such that:
a*(-1/4) = -1
a = -4*-1 = 4
a =4
So the line perpendicular to the given one is:
y = 4*x + b
Where b can be any real number.

could one side length of a function ever produce two different perimeters?
Answer: A perimeter is the total length of all the sides of a polygon. It is calculated by adding up the lengths of all the sides of the polygon. For a polygon with distinct and non-overlapping sides, each side length contributes exactly once to the perimeter. So in such case, a side length of a polygon can never produce two different perimeters.
However, it's worth mentioning that, one side length of a function could be a side of a polygon and the other could be a side of another shape. Also, it's possible that a single side length of an object is connected to a different set of side length, generating different perimeters.
For example, the length of an arc of a circle can be considered as a "side length" of the circle and it can be used to calculate both the perimeter of the arc and the circumference of the full circle, which are different measurements.
Also, a circular pool has a radius, but it's perimeter is the circumference, and this length is produced by the same radius but it's a different perimeter from the length of the radius.
In summary, a side length can produce different perimeter if we are talking about different shapes and measurements.

The Measures of two sides of a triangle are 12 and 13. Use an inequality to express the range of the measure of the third side, m.
A. 1 < m < 15
B. 1 < m < 25
C. 12 < m < 25
D. 0 < m < 11
The required inequality expression for the third side is 1 < m < 25. The correct option is (B).
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The sides of the triangle are given as 12 and 13 units respectively.
As per the rule for sides of a triangle, the third side is always less than the sum and greater than the difference of two sides.
Then, the inequality can be written as,
13 - 12 < m < 13 + 12
⇒ 1 < m < 25
Hence, the measure of third side can be written in inequality as 1 < m < 25.

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that 400 people are asked if they drink tea.
7/10 say Yes and 20% of the people who say Yes drink at least 3 cups each day
7/10 of 400 is 280
Which means 280 people drink tea.
The remaining people does not drink tea.
Remaining =400-280=120.
Now let us find 20% of 280
20/100×280
0.2×280=56
So 56 drink at least 3 cups each day.
280-56=224

The term decimal in math is defined as the numbers, which consist of two parts namely, a whole number part and a fractional part separated by a decimal point.
Here we have given that the product of 3 student tickets at $4.
Here we have know that the ticket cost for 3 students is $4.
Then the cost of one person is calculated by dividing the cost by the number of students then we get,

1.write a function that correctly depicts this scenario
2. How much will this cost 10 years from now ( round your answer to the nearest cent)
3 how much did this cost 15 years ago ( round your answer to the nearest cent
Answer:
The function that correctly depicts the scenario is:
cost(n) = 18.50 * 1.06^n
This function takes the number of years n as input and returns the cost of eating at the all-you-can-eat buffet after n years.
The cost of eating at the all-you-can-eat buffet 10 years from now can be calculated as follows:
cost(10) = 18.50 * 1.06^10 ≈ $30.59
The cost of eating at the all-you-can-eat buffet 15 years ago can be calculated as follows:
cost(-15) = 18.50 * 1.06^(-15) ≈ $8.01
