Find the solutions to x2 = 8.
A. X = +2.2
B. x= 12,4
C. X = +4-2
D. = +4.6
Answer:
x = ± 2√2
Step-by-step explanation:
Assuming "x2" is x^2 or "x squared", the answer can be derived from "square-rooting" both sides.
√ x^2 = √ 8
Then we simplify.
x = ± 2√2

Holaa, ¿cómo están?, ¿podrían ayudarme?,es urgente. Necesito saber 3 propiedades de la radicación,si alguien por favor las sabe o al menos sabe 1 o 2 por favor díganme, gracias!
Answer:
(i) La raíz enésima de un producto de dos números es igual al producto de las raíces enésimas de cada número del producto:
[tex]\sqrt[n]{a\cdot b} = \sqrt[n] {a}\cdot \sqrt [n] {b}[/tex], [tex]a,b\in \mathbb{R}[/tex], [tex]n\in \mathbb{N}[/tex]
(ii) La raíz enésima de una división entre dos números es igual a la división de la raíz enésima del numerador y la raíz enésima del denominador:
[tex]\sqrt [n]{\frac{a}{b} } =\frac{\sqrt[n]{a}}{\sqrt [n] {b}}[/tex], [tex]a,b\in \mathbb{R}[/tex], [tex]n\in \mathbb{N}[/tex]

put the quadratic into vertex form and state the coordinates of the vertex
y = x² + 6x - 41
Answer:
The vertex form of the quadratic: y = (x - 1)² + 2
Coordinates of vertex: (1, 2)
Step-by-step explanation:
The vertex form of an equation of the parabola is: f(x) = a(x - h)² + k
where (h, k) is the vertex. So:
x - h = x - 1 ⇒ h = 1
+ k = +2 ⇒ k = 2 -------------------------------------------------------------------------------

There are eight pints of lemonade an equal amount of lemonade is poured into 15 cups how much is in each cup
Answer: 8/15
Step-by-step explanation:
From the question, we are given the information that there are eight pints of lemonade and that an equal amount of lemonade is poured into 15 cups.
The amount of lemonade that's in each cup will be gotten by dividing the total pints of lemonade by the number of cups. This will be:
= 8 pints / 15
= 8/15 pints of lemonade

Whats 9*20(10+20) First Answer Gets Brainliest
Answer:
Your answer would be 5400.
Step-by-step explanation:
You have to follow PEMDAS for this one. You will start within the parenthesis and add 10 and 20 together to get 30. You would then times that by 20 and get 600. Finally, you would mulitply that by 9 and get 5400 as your answer..
Is 30 a typical test score? If so, explain your reasoning. If not, what is a typical test score?
Answer:
NO
Step-by-step explanation:
Failing a test is atypical for most kids. You have the occasional, but generally failing is something people don't really do. A typical test score varies from 95-70. It really just depends on the person. I sure hope you don't usually score 30's on tests.

Step-by-step explanation:
You spent $145 purchasing 3 student tickets and 7 adult tickets. Adult tickets cost $5 more than a student ticket. Find the cost of a student ticket. Find the cost of an adult ticket.
Answer:
$11 and $16
Step-by-step explanation:
let x be the cost of a student ticket then an adult ticket is x + 5 , then
3x + 7(x + 5) = 145 , that is
3x + 7x + 35 = 145
10x + 35 = 145 ( subtract 35 from both sides )
10x = 110 ( divide both sides by 10 )
x = 11
Student ticket costs $11 and adult ticket = x + 5 = 11 + 5 = $16

Help Please!!!!!!! Need Help!!!
Answer:
925
Step-by-step explanation:
In order to solve this summation formula, you need to first understand what it means. The summation symbol is tell you to add the terms in a sequence. Below the summation sign, there is a variable and number; the variable n is the index of summation and the number 1 is the lower limit of summation or the first value of the sequence. The number 25 above the summation sign is the upper limit (so there would be 25 terms, with the first being 1). The polynomial to the right of the summation symbol represents the explicit function for each term. For example, using this, the first term would be (3(1) - 2) and the second (3(2) - 2) and so on. This means the value of that equation is:
(3(1) - 2) + (3(2) - 2) + (3(3) - 2)... + (3(25) - 2)
One way to solve this is to write all 25 of the terms and add them, but since that's tedious, you can solve this by first doing the basic summation of 1 to 25 and then inputting that into the equation:
1 + 2 + 3... + 25 = (25 × 26)/2 (when the first number is one and the rate of change is 1, the sum of the terms in a sequence is (n*(n+1))/2)
= 325
Now, that you know what the sum of the sequence of terms 1 to 25 are, you can multiply this by the constant since if you break up the equation you would be multiplying 3 by 1 then 3 by 2 and so on until 25, or 3 × (1 + 2 + 3... + 25):
3 × 325 = 975
At this point, you just need to add (-2) × 25. You do this because since there are 25 terms, if you subtracted 2 each time, you would subtract 2 twenty-five times:
975 + ((-2) × 25)
= 975 - 50
= 925

In a survey, 400 people were asked to choose one card out of five cards labeled 1 to 5. The results are shown in the table. Compare the theoretical probability and experimental probability of choosing a card with the number 3.
Number 1 2 3 4 5
Frequency 32 96 128 112 32
Answer:
The value of the experimental probability is greater
Step-by-step explanation:
For the theoretical probability;
the probability that a card with the number 3 is selected is 1/5
We consider that the probabilities of each selection are equal, for the theoretical probability
For the experimental, we simply place the frequency of the selection 3 over the total
that will be 128/400 = 8/25
As we know that 8/25 is greater than 1/5
We can conclude that the value of the experimental probability is greater than that of the theoretical

The process of producing pain-reliever tablets yields tablets with varying amounts of the active ingredient. It is claimed that the average amount of active ingredient per tablet is at least 200 milligrams. The Consumer Watchdog Bureau tests a random sample of 70 tablets. The mean content of the active ingredient for this sample is 194.3 milligrams, while the standard deviation is 21 milligrams. What is the approximate p-value for the appropriate test
Answer:
p = 0.0116
Step-by-step explanation:
We are given;
Population mean; μ = 200 mg
Sample mean; x¯ = 194.3 mg
Standard deviation; σ = 21 mg
Sample size; n = 70
Formula for z-score is;
z = (x¯ - μ)/(σ/(√n))
z = (194.3 - 200)/(21/√70)
z = -5.7/2.51
z = -2.27
From the z-score table attached, the p-value at z = -2.27 is p = 0.0116
