Answer:
-10
Step-by-step explanation:
The required value of x is -1 when f(x) = –3 for the given function. The correct answer is option (D) -1.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The given table represents the function f(x).
x f(x)
-4 -66
-3 -29
-2 -10
-1 -3
0 -1
1 6
We are given a table representing the function f(x) and we need to find the value of x when f(x) = –3.
From the given table, we can see that when x = –1, f(x) = –3. Therefore, the answer is -1.
Hence, the correct option is:
(D) -1

how do you calculate surface area of trapezium with an angle
Answer: There are eight steps and two methods. I will be showing you one of them. If you're wondering, I am in 7th grade. I go to K12 online school.
Step-by-step Explanation: 1. Add together the lengths of the bases. The bases are the 2 sides of the trapezoid that are parallel with one another. If you aren’t given the values for the base lengths, then use a ruler to measure each one. Add the 2 lengths together so you have 1 value.[1]
For example, if you find that the top base (b1) is 8 cm and the bottom base (b2) is 13 cm, the total length of the bases is 21 (8 cm + 13 cm = 21 cm, which reflects the "b = b1 + b2" part of the equation).
2. Measure the height of the trapezoid. The height of the trapezoid is the distance between the parallel bases. Draw a line between the bases, and use a ruler or other measuring device to find the distance. Write the height down so you don’t forget it later in your calculation.[2]
The length of the angled sides, or the legs of the trapezoid, is not the same as the height. The leg length is only the same as the height of the leg is perpendicular to the bases.
3. Multiply the total base length and height together. Take the sum of the base lengths you found (b) and the height (h) and multiply them together. Write the product in the appropriate square units for your problem.[3]
In this example, 21 cm x 7 cm = 147 cm2 which reflects the "(b)h" part of the equation.
4. Multiply the product by ½ to find the area of the trapezoid. You can either multiply the product by ½ or divide the product by 2 to get the final area of the trapezoid since the result will be the same. Make sure you label your final answer in square units.[4]
For this example, 147 cm2 / 2 = 73.5 cm2, which is the area (A).

Michael has interviewed for two jobs. He feels that he has a 50% chance of getting an offer on Job A and a 60% chance of getting an offer on Job B. He also believes there is a 30% chance of getting an offer on both jobs. What is the probability that he receives an offer on at least one of the jobs?
A. 0.70
B. 0.25
C. 0.10
D. 0.80
Using Venn probabilities, it is found that the probability that he receives an offer on at least one of the jobs is given by:
D. 0.80
What is a Venn probability?In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this problem, we have that:
50% chance of getting an offer on Job A, hence P(A) = 0.5.60% chance of getting an offer on Job B, hence P(B) = 0.6.30% chance of getting an offer on both jobs, hence [tex]P(A \cap B) = 0.3[/tex].Then, the probability of getting an offer on at least one job is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.5 + 0.6 - 0.3 = 0.8[/tex]
Hence option D is correct.

What is the solution for x in the equation?
1/2 - x + 3/2 = x - 4
The solution to the equation 1/2 - x + 3/2 = x - 4 is x = 3.
We have Equation 1/2 - x + 3/2 = x - 4
Now, solving the equation for x we get
/2 - x + 3/2 = x - 4
First, let's combine the like terms on both sides of the equation:
(1/2 + 3/2) - x = x - 4
4/2 - x = x - 4
2 - x = x - 4
Next, let's move the term with x to the left side by adding x to both sides:
2 - x + x = x - 4 + x
2 = 2x - 4
Then, let's move the constant term -4 to the right side by adding 4 to both sides:
2 + 4 = 2x - 4 + 4
6 = 2x
6/2 = 2x/2
3 = x
Therefore, the solution to the equation is x = 3.
