The approximate distance from the sun to Earth is miles greater than the approximate distance from Earth to the moon by 9.276 × 10^7.
What is the scientific notation?Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format.
In this case, the approximate distance from Earth to the moon is 240 thousand miles. This will be 2.4 × 10^5
The approximate distance from Earth to the sun is 93 million miles. This will be:
= 9.3 × 10^7
The difference will be:
= (9.3 × 10^7) - (2.4 × 10^5)
= 9.276 × 10^7

The effectiveness of a blood-pressure drug is being investigated.
An experimenter finds that, on average, the reduction in systolic blood pressure is 55.8 for a sample of size 29 and a standard deviation 7.9.
Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).
Assume the data is from a normally distributed population.
Answer as a tri-linear inequality accurate to 3 decimal places.
A tri-linear inequality for the estimate of the drug that would lower a typical patient's systolic blood pressure (using a 90% confidence level) is; 53.3 ≤ x-bar ≤ 58.3.
Explain the term tri-linear inequality?Equal does not imply inequality. Tri signifies three. The range is defined in terms of inequalities by the tri-linear inequality.For the stated question-
Average of reduction in systolic blood pressure μ = 55.8.
Standard deviation s = 7.9.
Sample of size n = 29
The confidence interval is estimated as-
μ - t₀.₀₅(s/√n) ≤ x-bar ≤ μ + t₀.₀₅(s/√n)
Put the values-
55.8 - t₀.₀₅(7.9/√29) ≤ x-bar ≤ 55.8 + t₀.₀₅(7.9/√29)
On simplifying,
53.3 ≤ x-bar ≤ 58.3
Thus, a tri-linear inequality for the estimate of the drug that would lower a typical patient's systolic blood pressure (using a 90% confidence level) is; 53.3 ≤ x-bar ≤ 58.3.

What is equation straight line?
Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.
Given that a= -1.24 and b=33.966, the regression equation is y= axe + b y= -1.24x + 33.966.
Here, "y" stands for the maximum number of situps an individual may perform, and "x" stands for the daily television viewing hours.
The estimated number of situps for a person who watches x=2 hours of TV is y=-1.24*2 + 33.966 y= -2.48 + 33.966 y= 31.486
Hence, The estimated number of situps is 31.486.

Another karaoke location, Sounds of the Sea, is charging $15 for 5 songs. Construct a graph to model the relationship between cost and number of songs.
The function that represent the proportional relationship between cost and number of songs is y = 3x and it's graph is attached below
Linear FunctionA linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line'b' is the y-intercept of the line'x' is the independent variable'y' (or f(x)) is the dependent variableTo find the relationship between cost and number of songs, we can write a proportional relationship for this
y = mx
m = constant of proportionality
15 = m(5)
m = 15 / 5
m = 3
The constant of proportionality is 3

every rational number has a decimal expansion, so we could apply this same argument to show that the set of rational numbers between 0 and 1 is uncountable. however, because we know that any subset of q must be countable, the proof of theorem 1.6.1 must be flawed.
Every rational number can be expressed in decimal form. This argument cannot be used to demonstrate that rational numbers between 0 and 1 are countable. We frequently use this fact to demonstrate that rationals are countable since every rational number has a decimal representation that terminates on a non-teminating repeating sequence.
Rational number:
P/Q is the format for rational numbers, where p and q are open-ended integers and q 0. Thus, natural numbers, whole numbers, integers, fractions of integers, and decimals are all examples of rational numbers (terminating decimals and recurring decimals). The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.

bag contains 9 real diamonds and 5 fake diamonds. if 9 diamonds are picked from the bag at random, what is the probability that all of them are real?
The probability that all of them are real is 0.01875 or 1.875%
If the diamonds are replaced after each draw:
The probability of drawing a real diamond is 9/14, found by making the numerator the number of real diamonds and adding the total number of diamonds to find the denominator. 5+9 = 14.
To find the probability of all 9 diamonds drawn being real, multiply 9/14 by itself 9 times. = 387420489/ 20661046784. This creates a probability of 387420489/ 20661046784. This cannot be reduced because there is no common factor. To express as a decimal, divide. 387420489/ 20661046784 = 0.01875. To turn this into a percent, multiply by 100. 0.01875*100 = 1.875

As per the volume of the rectangular tank, the dimensions are 13.78 x 379.82 x 13.78
Volume of rectangle:
The general formula to calculate the volume of the rectangle is
V = length x width x height.
Given,
A rectangular tank that is 5234 ft^3 with a square base and open top is to be constructed of sheet steel of a given thickness.
Here we need to find the dimensions of the rectangular tank,
As per the given volume of rectangular tank, when we equate this with the formula, then we get,
=> 5234 = length x width x height.
Let us consider the length and the width are equal then we get the value of height as.
=> height = 5234/length
So, the value is calculated by using the surface area formula,
=> A = length² + 5234/length
When we differentiate the surface area with respect to
=> dA/dl = 2l - 5234/l²
To minimize the surface area, so dA/dl = 0,
=> 2l = 5324/l²
=> 2l³ = 5234
=> l³ = 2617
=> l = ∛2617
Therefore, the value of length is 13.78
Then the height is calculated as.
