Answer:
[tex] \sf \: x = 5[/tex]
Step-by-step explanation:
Given equation,
→ y = 4x - 2
Now we have to use,
→ y = 18
Then the value of x will be,
→ y = 4x - 2
→ 18 = 4x - 2
→ 18 + 2 = 4x
→ 20 = 4x
→ 4x = 20
→ x = 20 ÷ 4
→ [ x = 5 ]
Hence, the value of x is 5.

Find all the missing sides and angles of this triangle. Round to the nearest tenth if necessary.
Right triangle ABC. Hypotenuse = 7 units. Angle B = 70 degrees.
Triangle ABC with a hypotenuse of 7 units and angle B equal to 70 degrees,
side AC is 5.3 units side BC is 4.7 units. Angle C is 20 degrees.How to find the sides of the triangleSince triangle ABC is a right triangle and angle B is 70 degrees, it can be deduced that angle C must be 90 - 70 = 20 degrees.
assuming
length of side AC = a
length of side BC = b.
Using the Pythagorean theorem, we can find the values of a and b.
a^2 + b^2 = 7^2
a^2 = 7^2 - b^2
a = √(7^2 - b^2)
Using the tangent function
tan C = b/a
tan 20 = b/√(7^2 - b^2)
Solving for b, we get:
b = tan(20) * √(7^2 - b^2)
We can use numerical methods to find the approximate value of b. Using a calculator, we can find that b is approximately 4.7. Rounding to the nearest tenth, b is 4.7 units.
Finally, using the Pythagorean theorem again, we can find the value of a:
a^2 + b^2 = 7^2
a^2 = 7^2 - b^2 = 7^2 - 4.7^2
a = √(7^2 - 4.7^2)
a = √(7^2 - 22.09)
Using a calculator, we can find that a is approximately 5.3. Rounding to the nearest tenth, a is 5.3 units.

Step-by-step explanation:
the mean of a data set is 36.71 and the sample standard deviation s is 3.22 approximately what percentage of measurements will be between 31.88 and 41.54?
Approximately 90.7% of measurements will be between 31.88 and 41.54.
To find the percentage of measurements that will be between 31.88 and 41.54, we need to use the standard deviation to find the number of standard deviations away from the mean that 31.88 and 41.54 are, and then use a standard normal table to find the corresponding proportion of data within that range.
First, we'll find the z-score for 31.88:
z = (31.88 - 36.71) / 3.22 = -1.49.
Similarly, the z-score for 41.54 is:
z = (41.54 - 36.71) / 3.22 = 1.34.
Now we can use a standard normal table to find the proportion of data between -1.49 and 1.34 standard deviations from the mean. This proportion is approximately 0.907, meaning that approximately 90.7% of measurements will be between 31.88 and 41.54.

The numerical value of the standard deviation is never (B) less than the variance and is never negative.
What is the standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.
While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
The standard deviation's numerical value is always greater than the variance and can never be negative.
The lowercase Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation.

Is the trapezoidal rule an overestimate or underestimate?
The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.
What is trapezoidal rule?The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral.

Michael is 3 times as old as Brandon. 18 years ago, Michael was 9 times as old as Brandon.
How old is Michael now?
Currently, Michael is 72 years old
How old is Michael now?Let's represent Michael's current age as "x".
Then Brandon's current age is x/3.
18 years ago, Michael's age was x-18
Brandon's age was x/3-18.
18 years ago, we can write the equation:
x - 18 = 9 * (x/3 - 18)
So, we have
x - 18 = 3x - 162
Evaluate the like terms
2x = 144
Divide by 2
x = 72
So, Michael is 72 years old now.
