At a carnival booth, customers had to guess the number of jelly beans in a jar. Samantha guessed there were 375 jelly beans. The actual amount of jelly beans in the jar was 250. What is Samantha's percent error?
Answer:
150
Step-by-step explanation:
The required percent error by Samantha is 50%, as of the given condition,
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is the error?Errors are discrepancies between values that are seen and natural truths.
Here,
Samantha guessed there were 375 jelly beans.
The actual amount of jelly beans in the jar was 250.
Error percentage = 375-250 / 250 × 100
= 0.5 × 100
= 50%
Thus, the required percent error by Samantha is 50%, as of the given condition.

Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The given expression can be written as,
2⁶ = 2 × 2 × 2 × 2 × 2 × 2
= 4 × 16
= 8 × 8
Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.

Answer:
7. y=x-2, 8. y=3/2x+4, 9. y=-3/4x+8, 10. y=2x-7, 11. y=-5x-3, 12. y=4x-5, 13. y=-3x-1, 14. y=-1/2x+1, 15. y=3/2x+4
Step-by-step explanation:
First you have to plug in the points into y2-y1/x2-x1. This would make it -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.
This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.

An angle measures 106.4° less than the measure of its supplementary angle. What is the measure of each angle
Answer:
The two supplementary angles are 10 and 170 degrees.
Step-by-step explanation:
Two angles are supplementary when that add up to 180 degrees. In this case, we are given that one of the two angles is 160 degrees more than the other. We can construct the following equation. x + ( x + 160 ) = 180 x
represents the degree measure of the smaller angle. Now, all we need to do is solve the equation for x. 2 x + 160 = 180 2 x = 20 x = 10
Now that we have the value of the smaller angle, we can easily solve for the larger angle. We are told that it is 160 degrees larger than the other one.
10 + 160 = 170. Therefore, the two supplementary angles are 10 and 170 degrees.

The equation has a solution of = =9
С
The equation has a solution of c = 424
D
The equation has infinitely many solutions,
Answer:
If Step is 53 = 477 then no solution exist
If Step is 53 x = 477 then there exist a unique solution x = 9
Step-by-step explanation:
Given - Ramon solves a linear equation. One of the steps in his work is
53 = 477
To find - Which of these describes the solution to the equation that Ramon
solves?
Proof -
As given, One of the steps in his work is 53 = 477
There are 2 cases possible -
Case I:
If his step is 53 = 477
Then, the equation has no solution because 53 ≠ 477
Case I:
If his step is 53 x = 477
Then, the equation has a solution because x = [tex]\frac{477}{53}[/tex] = 9
⇒The equation has a solution of x = 9.
