1. 49/56 2. 25/30 I really need help with my work to
Answer:
B. [0.802], [0.978]
Step-by-step explanation:
n=49
p=.89
confidence level of 95% has a z value of 1.960
z*= 1.960
z*=qnorm(1.95/2)
p+/-z* multiplied by sqrt[ P * ( 1 - P ) / n ]
p+/-z*times(√(p)(1-p)/n)
.89+/-1.960* (square root of (.89)(.11)/49))

Answer:
1.) Step-by-step In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1] 2
2.) Architecture and Construction. Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.
Without the answer choices, its hard to say for sure. However, it seems like you're dividing both sides by 5 to isolate x. So your teacher is most likely aiming for "division property of equality". Alternatively, you can multiply both sides by 1/5 = 0.2 to achieve the same result. So you're also using the multiplication property of equality. Note: division and multiplication are very closely related operations.
