The expression 7⁻¹ ÷ 7⁻² is a quotient expression, and the value of the quotient 7⁻¹ ÷ 7⁻² is 7
How to evaluate the exponents?The expression is given as:
7⁻¹ ÷ 7⁻²
Rewrite the expression using the product sign
7⁻¹ ÷ 7⁻² = 7⁻¹ * 7²
Apply the product rule of indices
7⁻¹ ÷ 7⁻² = 7⁻¹⁺²
Evaluate the sum of the exponents
7⁻¹ ÷ 7⁻² = 7¹
Evaluate the exponent
7⁻¹ ÷ 7⁻² = 7
Hence, the value of the quotient 7⁻¹ ÷ 7⁻² is 7

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.
PLEASE HELPP !!! Find the volume of the sphere.
The volume of the sphere with a radius of 2 units is 17.541π cubic units
Volume of a sphereA 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

a. 27
b.28
c.38
Answer:
C). 38
Step-by-step explanation:
The range is the measurement of the difference between values in a data set. To find the range, subtract the lowest value from the greatest value.
2, 5, 19, 7, -5, 33, 26, 15, 12
-5, 2, 5, 7, 12, 15, 19, 26, 33
Lowest value,
⇒ -5
Greatest value,
⇒ 33
33 - (-5)
⇒ 38
Hence, the range/answer is 38. ⇒ option c.
What is the sum of the first 20 terms of the series below?
Answer:
Step-by-step explanation:
Now to find the sum of first 20 terms, substitute n=20,a=−1 and d=4 in S n = 2n [2a+ (n−1)d] as follows: S 20 = 220 [(2×−1)+(20−1)4]=10[−2+(19×4)]=10(−2+76)=10×74=740 Hence, the sum of first 20 terms is 740.
the sum of the first 20 terms of the series below is C.

Pretty hard question in geometry pls help me
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.
