Step-by-step explanation:
Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
Answer:
linear function is a function whose graph is a line. Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line.
Step-by-step explanation:
Answer:
- 1 + 2i
Step-by-step explanation:
Given
(1 + i) + (- 2 + i) ← remove parenthesis
= 1 + i - 2 + i ← collect like terms
= - 1 + 2i
Given the data temperatures to be;
We would require the following to get the 98% confidence interval of the mean body temperature.
Mean, Standard deviation, sample size, Probability of a confidence interval of 98%.
Using a calculator, we can get the mean to be
The standard deviation would be derived to be;
The sample size can be gotten from the question to be;
The probability value of a 98% confidence interval is given to be 2.33
We can then derive the answer using the formula below;
We would substitute into the formula
