Answer:
Rewriting [tex]6^{-2}[/tex] without an exponent we get [tex]\mathbf{\frac{1}{36}}[/tex]
Step-by-step explanation:
We need to rewrite the following without an exponent. [tex]6^{-2}[/tex]
We need to solve the exponent to find the result.
We know the exponent rule: [tex]a^{-b}=\frac{1}{a^b}[/tex]
Now using this rule to solve the equation:
[tex]6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}[/tex]
So, Rewriting [tex]6^{-2}[/tex] without an exponent we get [tex]\mathbf{\frac{1}{36}}[/tex]
A researcher measures water drawn from 52 points a city's system in order to check the claim that the average lead content in the city's water is no more than 7 micrograms per deciliter. She finds an average of 5 micrograms per deciliter. Please match each of these terms:
a. Population
b. Sample
c. Parameter
d. Statistic
1. the 52 water draws
2. 7 micrograms per deciliter
3. 5 micrograms per deciliter
4. 7/52 lead measurements
Answer:
a. Population - 1. the 52 water draws
b. Sample - 4. 7/52 lead measurements
c. Parameter - 2. 7 micrograms per deciliter
d. Statistic - 3. 5 micrograms per deciliter
Step-by-step explanation:
If the value is from a population, it is a parameter.
Otherwise, if the value is from a sample, it is a statistic.
A population is an entire group of people, or of something, while a sample is a small number of observations from this group.
In this question:
The entire population is the measures drawn from the 52 points in the city's system.
In the entire system, the average is no more than 7 micrograms per deciliter. This is a value from the entire population, so this is a parameter.
To found the average of 5 micrograms, she took 7 of these measurements. So the 7 measurements are the sample and the average os 5 micrograms is a statistic.
So the correct matching is:
a. Population - 1. the 52 water draws
b. Sample - 4. 7/52 lead measurements
c. Parameter - 2. 7 micrograms per deciliter
d. Statistic - 3. 5 micrograms per deciliter

Which is an equation of the line through the origin and (-4,-9)?
Note: Origin point = (0,0).
[tex] \begin{cases}(x_1, y_1) = ( - 4, - 9) \\ (x_2, y_2) = ( 0, 0) \end{cases}[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} \\ m = \frac{0 - ( - 9)}{0 - ( - 4)} \\ m = \frac{0 + 9}{0 + 4} \Longrightarrow \frac{9}{4} [/tex]
Slope-Intercept[tex]y = mx + b \\ \begin{cases} \sf{m = slope} \\ \sf{b = y - intercept} \end{cases}[/tex]
Rewrite the equation by substituting m = 9/4 in the equation.
[tex]y = \frac{9}{4} x + b[/tex]
Find the value of b.Because the graph passes through the origin point. That means the y-intercept is (0,0).
Therefore we rewrite the equation again to
[tex]y = \frac{9}{4} x + 0 \\ y = \frac{9}{4} x[/tex]
Answer[tex] \large \boxed{y = \frac{9}{4} x}[/tex]

If A1
= 9 and An = An-1 + 4 then find the value of A5
BRAINLIEST TO ANYONE
Answer:
25
Step-by-step explanation:
a1 = 9
a2 = a1 + 4
a2 = 9 + 4
a2 = 13
a3 = a2 + 4
a3 = 13 + 4
a3 = 17
a4 = 21
a5 = 21 + 4
a5 = 25
This can more easily be done by using this formula
L = a1 + (n - 1) * d
a1 = 9
n = 5
d = 4
L = 9 + (5 -1)*4
L = 9 + 4*4
L = 9 + 16
L = 25
During the 2013 Major League Baseball season, a home run over the left field wall typically reached a maximum height of 81 feet, and would have traveled a distance of 378 feet from home plate. Assuming the average batter hits the ball three feet from the ground, write a function for the trajectory of the average home run.
Answer:
The Green Monster is a popular nickname for the 37-foot-2-inch-high (11.33 m) left field wall at Fenway Park, home to the Boston Red Sox baseball team. The wall is 310 feet (94 m) from home plate and is a popular target for right-handed hitters.

mr. jones asks his students to generate the next two numbers in the sequence
Answer:
7 0
Step-by-step explanation:
The next two numbers of the series is 27.5 and 44.
What is sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The complete question is:
Mr. jones asks his students to generate the next two numbers in the sequence beginning –5.5, 11, .... taquan suggests that the sequence is geometric and the next two numbers are –22 and 44. julia suggests that the sequence is arithmetic and the next two numbers are 27.5 and 44. which best explains which student is correct?
Given AP = -5.5, 11, ...
a = 5.5
d= 11 - (-5.5) =16.5
Now, a₃ = a₂ + d
a₃ = 11 + 16.5
a₃ = 27.5
and, a₄ = 27.5 + 16.5
a₄ = 44
Now, Taquan case:
a = -5.5
r = 110/-5.5
r = -2
now, a₃ = -2(11) = -22
a₄ = -2(-22) = 44

what is a cubic polynomial function with zeros 3,3 and -3? show your work.
Answer:
Cubic polynomial function with zeros 3,3 and -3 is [tex]\mathbf{x^3-3x^2-9x+27=0}[/tex]
Step-by-step explanation:
We need to find a cubic polynomial function with zeros 3,3 and -3.
If zeros of polynomial are: 3,3,and -3
we can write:
x=3, x=3, x=-3
Or
We can write:
x-3=0, x-3=0, x+3=0
Now, we can write them as:
(x-3)(x-3)(x+3)=0
Multiplying the terms, we can find the polynomial:
[tex](x-3)(x-3)(x+3)=0\\(x(x-3)-3(x-3))(x+3)=0\\(x^2-3x-3x+9)(x+3)=0\\(x^2-6x+9)(x+3)=0\\x(x^2-6x+9)+3(x^2-6x+9)=0\\x^3-6x^2+9x+3x^2-18x+27=0\\x^3-6x^2+3x^2+9x-18x+27=0\\x^3-3x^2-9x+27=0[/tex]
So, cubic polynomial function with zeros 3,3 and -3 is [tex]\mathbf{x^3-3x^2-9x+27=0}[/tex]
