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

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.

10 is the mean of the number that is missing.

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: 34

Step-by-step explanation:

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

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.

Step-by-step explanation:

The volume of the sphere with a radius of 2 units is 17.541π cubic units

A sphere is a solid 3-dimensional figure. The volume of a sphere is expressed as:

V = 2/3πr^3

where:

r is the radius of the sphere:

Given the following

r = 2 units

Substitute the given parameters

V = 2/3(π) * 2^3

V = 2/3 * π * 8

V = 16.75π/3

V = 17.541π cubic units

Hence the volume of the sphere with a radius of 2 units is 17.541π cubic units
