What is the solution to the inequality x2 >49 (x squared is greater than or equal to 49) plz help
To solve the inequality x² ≥ 49, take the square root of both sides and consider both positive and negative roots. The solutions are x ≤ -7 or x ≥ 7.
To solve the inequality x² ≥ 49, we need to consider the values of x that satisfy this condition. Let's break it down step-by-step:
Step-by-Step Explanation
x² ≥ 49. To solve this, we can take the square root of both sides of the inequality. Remember, when taking the square root of both sides, we must consider both the positive and negative roots.
Solve for x: |x| ≥ √49.
Since √49 = 7, the inequality becomes: |x| ≥ 7.
This implies x can be greater than or equal to 7 or less than or equal to -7.
Therefore, the solution is: x ≤ -7 or x ≥ 7.
In interval notation, this solution is written as: x ∈ (-∞, -7] ∪ [7, ∞).

The function f(x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2,–1)} Which equation is true?
The correct equation matches the set of ordered pairs of functions:
C.f (0) = 6
Further explanationSet A to set B is said to be a function if each member of set A pairs is exactly one member of set B
So, one value of x is only assigned to one value of y
or it has only one relationship for each input value
A function can be expressed in the form of a cartesian diagram, the set of ordered pairs, or arrow diagram
If y is a function of x, then y = f (x)
where x is the independent variable and y is the dependent variable
x is the domain and y is the result area or range
A function can be write as ordered pair
Ordered pairs because we write the input first, and then the output
Can be described in form
(input, output)or
[tex]\large{\boxed{\bold{(x,f (x))}}[/tex]
So A function can be formed as a set of ordered pairs:
For example a set of ordered pairs
(2,4), (3,5), (4,6)input values (as domain) 2,3,4
output values (as range) 4,5,6.
We complete the questions with answer choices :
The function f (x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2, –1)}:Which equation is true?
f(-10)=1
f(2)=-10
f(0)=6
f(1)=-10
Let see the answer choices :
f (-10) = 1values x = -10, f (x) = y = 1, ordered pairs (-10,1)
f (2) = - 10values x = 2, f (x) = y = -10, ordered pairs (2, -10)
f (0) = 6value x = 0, f (x) = y = 6, ordered pairs (0.6)
f (1) = - 10values x = 1, f (x) = y = -10, ordered pairs (1, -10)
So the answer choices that correspond to the set of ordered pairs of functions above are choices C.f (0) = 6

A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random. What is the theoretical probability of picking a green marble
Answer:
The theoretical probability of picking a green marble is 0.55. Step-by-step explanation:
Given : A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random.
To find : What is the theoretical probability of picking a green marble?
Solution :
Theoretical probability is defined as the number of favorable outcome divided by total number of outcome.
Yellow Marble = 20
Green Marble = 55
Purple Marble = 25
Total Number of marble = 20 + 55 + 25 = 100
Let G be the event of getting green marble.
So, Favorable outcome = 55
Theoretical probability of picking a green marble is
[tex]P(G)=\frac{55}{100}[/tex]
[tex]P(G)=\frac{11}{20}[/tex]
[tex]P(G)=0.55[/tex]
Therefore, The theoretical probability of picking a green marble is 0.55.

At one college, GPA's are normally distributed with a mean of 2.7 and a standard deviation of 0.5. What percentage of students at the college have a GPA between 2.2 and 3.2?
Final answer:
About 68.27% of students at the college have a GPA between 2.2 and 3.2 because these values correspond to z-scores of -1 and +1, respectively, in a normal distribution.
Explanation:
To find the percentage of students at the college who have a GPA between 2.2 and 3.2, we will use the properties of the normal distribution. The mean GPA is 2.7 and the standard deviation is 0.5.
First, we calculate the z-scores for the GPAs of 2.2 and 3.2:
z-score for 2.2 = (2.2 - 2.7) / 0.5 = -1
z-score for 3.2 = (3.2 - 2.7) / 0.5 = +1
The z-score represents the number of standard deviations a data point is from the mean. In a standard normal distribution, the percentage of data between z-scores of -1 and +1 is approximately 68.27%.
Therefore, about 68.27% of the students at the college have a GPA between 2.2 and 3.2.
