Jake is exploring a statistical question by gathering data and performing calculations on the gathered data. Which could be Jake's statistical question?

His statistical question could be, How much food does a dog eat per week? Let's assume he owns several dogs.

Step-by-step explanation:

To answer this question, Jake gathers data for several weeks and performs several calculations. From his calculations and findings, the answer might be, 'A dog eats from 10 to 12 pounds of food every week'. Also his answers might vary due to the sizes of each dog.

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
