Answer:
The percentage error in the prediction = 10.20%
Step-by-step explanation:
A sports broadcaster predicts a basketball team will score 88 point me in the next game.
If the team has actually scored 98 points we have to find the percentage error in the broadcaster's prediction.
The deviation of the prediction from the actual value = 98 - 88 = 10.
The formula for finding error percentage = 
= 
= 10.20 %
The percentage error = 10.20%
Answer:
The area of the shaded region is about 58.9 square inches.
Step-by-step explanation:
To solve this question, let's recall some facts.
We know that the area of a circle can be defined as the following:

where r is the radius of the circle.
We too know that circles have a diameter and a radius. The diameter of a circle is the distance a line that connects two points on a circle with its center, and the radius is half of the diameter.
We also know that figures can touch each other, or be in tangent with each other. For the sake of simplicity, we're going to assume that the shaded circles are in tangent with each other, or touch each other. Because they touch each other, these three circles can share 5 in. of the 15 in. rectangle. This means that the circles are 5 in. in diameter, or 2.5 in in radius.
Now, we can solve the problem.
Because we have 3 circles, each with 2.5 in. radii, we can have the following expression which represents the total area of these circles:




After approximation, I can conclude that the area of the shaded region is 58.9 square inches.

Step-by-step explanation:
The true statement, regarding the signal of the graphed function, is given by:
F(x) > 0 over the interval (–∞, –4).
<h3>When a function is positive and when it is negative?</h3>
Looking at it's graph, we have that:
- The function is positive when it is above the x-axis.
- The function is negative when it is below the x-axis.
Researching this problem on the internet and looking at the graph of the function, the function is negative for <u>all values to the right of x = -4</u>, and positive to the left, hence the correct statement is given by:
F(x) > 0 over the interval (–∞, –4).

Answer:
16.7%
Step-by-step explanation:
Each of the six faces of a six-faced die shows one of the numbers: 1, 2, 3, 4, 5, 6.
A roll of a die is equally likely to land on any face, so the total number of possible outputs is 6, corresponding to the number of faces on the die.
The desired outcome here is 3, meaning the face that shows the number 3. Only one face has the number 3, so the number of desired outcomes is 1.
p(event) = (number of desired outcomes)/(total number of possible outcomes)
p(3) = 1/6 = 0.16666... = 16.7%
