Find the value of x for the given equation : 2 (x-1) - 6 =24
Answer:
x = 16
Step-by-step explanation:
2(x - 1) - 6 = 24 ( add 6 to both sides )
2(x - 1) = 30 ( divide both sides by 2 )
x - 1 = 15 ( add 1 to both sides )
x = 16

math question about statistics
Answer:
Mean = 29300
median = 23500
Modal = 23000
Step-by-step explanation:
Mean = Add them all and divide by 10
= 29300
median = average of (rank of 5th and 6th)
= (23000 + 24000) /2
= 23500
Modal = appear the most
= 23000

What is the value of y?
Answer:
y = 70
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
y = 1/2(92+48)
y = 1/2(140)
y = 70
The mean of this data set is 9. What number is missing?
11,20,_,3,1
10 is the mean of the number that is missing.
What is mean?A property of an assortment of data that represents an average is called the mean. Depending on the nature of the information as well as the kind of average you require, one can compute the mean theoretically employing any of the several ways. Scheming the data distribution constantly allows one to visually determine the mean as well.
Let the missing number be x.
The sum of all the numbers will be
= 11 + 20 + 3 + 1 + x
= 35 + x
The total number is 5.
The mean is given to be 9.
The mean will be
9 = (35 + x) / 5
9 * 5 = 35 + x
45 = 35 + x
10 = x

Answer:
x = [tex]\frac{15}{11}[/tex]
Step-by-step explanation:
[tex]\frac{3}{5}[/tex] x - [tex]\frac{1}{3}[/tex] x = x - 1
multiply through by 15 ( the LCM of 5 and 3 ) to clear the fractions
9x - 5x = 15x - 15
4x = 15x - 15 ( subtract 15x from both sides )
- 11x = - 15 ( divide both sides by - 11 )
x = [tex]\frac{-15}{-11}[/tex] = [tex]\frac{15}{11}[/tex]

The grades of a science test are normally distributed. Thanh finds that his grade on the test has a z-score of –2.5. Which of the following statements must be true?
PLEASE SHOW WORK!
A. Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
explanation
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
with very low p values are at the ends of the normal distribution.

[tex]A = (x_1,y_1) = (-3,2) \text{ and } B = (x_2, y_2) = (-6,-2)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-(-6))^2 + (2-(-2))^2}\\\\d = \sqrt{(-3+6)^2 + (2+2)^2}\\\\d = \sqrt{(3)^2 + (4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]
I used the distance formula. Alternatively, you can plot the two points and form a right triangle. Then use the pythagorean theorem. The distance formula is effectively a modified version of the pythagorean theorem.

Check the picture below, on the left side atop
AC is a diametrical line, and thus the angle that it makes is 180°, so the arcAB is obvious. Now, the angle ADB, well is an inscribed angle touching the arcAB.
Check the picture below, on the left side below
well, that triangle is a triangle made using the diametrical AC, and thus the angle ABC is an inscribed angle in a semicircle, now check the picture on the right side
when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one.
[tex]\cfrac{x}{6}~~ = ~~\cfrac{6}{13-x}\implies 13x-x^2=36\implies 13x=x^2+36 \\\\\\ 0=x^2-13x+36\implies 0=(x-9)(x-4)\implies x=AE= \begin{cases} 9~~\checkmark\\ 4 \end{cases}[/tex]
now, let's notice something, 4 is also a valid value, why we can't use 4?
well, let's notice, the segment AE is passed the half of AC, namely passed the center, since AC is 13, half that must be 6.5, so whatever AE is, it must be greater than 6.5, so the value 4 is no dice.
