Answer:
0.62
Step-by-step explanation:
In the picture attached, the table is shown.
We want to find the probability that a student uses the Internet, given that he or she is in eighth grade. Mathematically:
P(Internet | eighth grade) = P(Internet ∩ eighth grade)/P(eighth grade)
P(Internet | eighth grade) = (8/28)/(13/28) = 8/13 = 0.62
The solution to the equation 6x² - 12 = -1 is x = ±√(11/6). The correct option is A.
A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The given equation is as follows:
6x² - 12 = -1
To solve for x, we will first isolate the variable term by adding 12 to both sides of the equation.
6x² - 12 = -1
6x² = 11
Next, we will divide both sides by 6 to get x² by itself.
6x²/6 = 11/6
x² = 11/6
Take the squareroot of both sides of the equation.
We need to include both the positive and negative square roots because x² can be positive or negative.
x = ±√(11/6)
Therefore, the solution to the equation 6x² - 12 = -1 is x = ±√(11/6).

Answer:
(x -7)²
x = 7
Step-by-step explanation:
Given the quadratic function (polynomial):
x² - 14x + 49 = 0
The first term (x²) and the last term (49) are both perfect squares and the second term is the sum of the product of these two terms (-7 + -7 = -14):
(x - 7)(x - 7) = (x-7)²
Answer:
11/200
Step-by-step explanation:
The number 7 times 7 will be equal to 49.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that there is the number 49. The number is the multiple of two numbers.
The product of the two numbers equal to 49 will be calculated as:-
E = 7 x 7'
E = 49
Therefore, the two numbers will be 7 and 7 whose product is equal to 49.
