Hope I helped:P
Line DE is 4 squares and Line BC is 8 squares.
The length of line DE is 1/2 of line BC
If the scale factor is 1/5, then the area of the preimage is multiplied by <u>0</u><u>.</u><u>2</u> or <u>1</u><u>/</u><u>5</u> to calculate the area of the new image.
Answer: ![0.939\ or\ 93.9\%](https://tex.z-dn.net/?f=0.939%5C%20or%5C%2093.9%5C%25)
Step-by-step explanation:
Given
Survey shows that 16% of college students have dogs and 38% have HBO subscription
Probability that a random person have both is
![\Rightarrow P_o=0.16\times 0.38\quad [\text{As both events are independent}]\\\Rightarrow P_o=0.0608](https://tex.z-dn.net/?f=%5CRightarrow%20P_o%3D0.16%5Ctimes%200.38%5Cquad%20%5B%5Ctext%7BAs%20both%20events%20are%20independent%7D%5D%5C%5C%5CRightarrow%20P_o%3D0.0608)
The probability that the random person has neither of the two is
![\Rightarrow P=1-P_o\\\Rightarrow P=1-0.0608\\\Rightarrow P=0.939](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D1-P_o%5C%5C%5CRightarrow%20P%3D1-0.0608%5C%5C%5CRightarrow%20P%3D0.939)
Percent Change = New Value − Old Value|Old Value| × 100%
Example: There were 200 customers yesterday, and 240 today:
240 − 200|200|× 100% = 40200 × 100% = 20%
A 20% increase.
Percent Error = |Approximate Value − Exact Value||Exact Value| × 100%
Example: I thought 70 people would turn up to the concert, but in fact 80 did!
|70 − 80||80| × 100% = 1080 × 100% = 12.5%
I was in error by 12.5%
(Without using the absolute value, the error is −12.5%, meaning I under-estimated the value)
The difference between the two is that one states factual calculations and the other is a theoretical guess
