Answer:
No, the absolute value of a number is different from the opposite.
Step-by-step explanation:
For example, the absolute value of 4 is 4.
l4l = 4
But the opposite of 4 is -4.
Absolute value is ALWAYS positive, but the opposite of a positive number is a negative number.
Answer:
A. 47 degrees
Step-by-step explanation:
If both sides are equivalent in length, that means that the two remaining angles are also the same. Triangles have an interior angle sum of 180 degrees, so subtract the 86 of the angle known, and divide the remaining degrees by two to find each angle.
Answer:
32 hours
Step-by-step explanation:
14x + 250 < 22x
250 < 22x - 14x
250 < 8x
250/8 < x
x = 31.25 = 32 hours
Tim charge for 32 hrs: 14(32)+250= $698
Colorful paints charge for 22 hrs: $704
Using a calculator, the correlation coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
Using a calculator, we insert the points (x,y) to find the coefficient. In this problem, the points are given as follows:
(1, 5), (4, 8), (8, 3), (13, 10), (19, 13)
The coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.

Answer:
A.) $3,159.30
Step-by-step explanation:
We have been given that a boat costs $16,600 and decreases in value by 14% per year.
We will use exponential decay formula to solve our given problem.
, where,
y = Final amount,
A = Initial value,
r = Decay rate in decimal form.
Therefore, the value of boat after 11 years would be $3159.30 and option A is the correct choice.
