Answer:
20
Step-by-step explanation:
2 1/2 = 5/2
(5/2)/(1/8) = 20
<span>This characteristic of non-functions was noticed by I-don't-know-who, and was codified in "The Vertical Line Test": Given the graph of a relation, if you can draw a vertical line that crosses the graph in more than one place, then the relation is not a function.</span>
The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2. In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B
Answer:
The 95% confidence interval is
The pivot function used is
Step-by-step explanation:
From the question we are told that
The data given is 246 242 248 245 250 244 252 248 248 247 250 248 246 242 248 244 245 246 250 242
The sample size is
Given that the confidence level is 95% then the level of significance is
The degree of freedom is mathematically represented as
From the student t-distribution table the critical value of is
The mean is mathematically represented as
The standard deviation is mathematically represented as
The margin of error is mathematically represented as
The 95% confidence interval is mathematically represented as
=>
=>
The pivot function used is
Answer:
108 square feet
Step-by-step explanation:
This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)
Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of
A = s*s = 6*6 = 36 square feet
The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of
A = l*w = 12*6 = 72 square feet
Add those together to get the total area.
A(rect) + A(square) = 72 + 36 = <u>108 square feet</u>
