No, the simplified forms and rational expression are not equivalent
Answer:
99.7%
Step-by-step explanation:
Given that:
sample size (n) = 655
sample mean () = 43.29
Standard deviation = 2.75
Let's assume we are to estimate the percentage between $33.72 and $51.54
Then;
The test statistics at 33.72 is :
Z at 51.54
Using the empirical standard rule, the percentage will be 99.7%
Step-by-step explanation:
x=width of pool
2x=length of pool
the dimensions of the rectangle forming the walkway and the pool are x+4 and 2x+4
the area of this rectangle minus the area of the pool is 196 square feet
(2x+4)(x+4)-(x)(2x)=196
2x^2+4x+8x+16-2x^2=196
combine similar terms
12x+16=196
12x=196-16
12x=180
x=180/12
x=15 feet is the width of the pool
check: 34*19-30*15=196
646-450=196
196=196
Answer:
Nothing
Step-by-step explanation
This expression is not solvable. This expression is incomplete. You need something on the other side of the equal sign to solve this equation. For example: 3x+2y=10 now this is a solvable expression. I hope this helped you in some way!
The answer is D. $270.00.
To find this answer, you divide 37.80 by 14%.
