Step-by-step explanation:
In ️ BEA and ️ CED
EB=EC ----given
angle ABE= angle DCE --------- given
angle DEB= angle DCE -------vertically opposite angles are equal
Hence, ️ BEA is congruent to ️ CED
The best way to randomly choose the 100 families would be to allow a random number generator to come up with 100 families within a 50 radius of the amusement park.
Using this method would ensure that it is more randomised & not limited to people who come at a specific time or are in a specific area as well as it not be affected by subconscious bias of people when selecting people to survey.

-48.9582
Step-by-step explanation:
Negative times a positive is negative.
Answer:
Given Polynomial:

Factors of Coefficient of terms
80 = 5 × 16
32 = 2 × 16
48 = 3 × 16
Common factor of the coefficient of all term is 16.
Each term contain variable. So the Minimum power of b is common from all terms.
Common from all variable part comes b².
So, Common factor of the polynomial = 16b²
⇒ 16b² ( 5b² ) - 16b² ( 2c³ ) + 16b² ( 3b²c )
⇒ 16b² ( 5b² - 2c³ + 3b²c )
Therefore, Statements that are true about David's word are:
The GCF of the coefficients is correct.
The variable c is not common to all terms, so a power of c should not have been factored out.
In step 6, David applied the distributive property
Answer:
£265
Step-by-step explanation:
Total fraction of money spent= 
= 
Actual money spent =
* £636
= £371
Money he has left = £(636 - 371)
= £265
