Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 105 people in the 18-21 age bracket and finds that 89 of them respond and 16 refuse to respond. When 248 people in the 22-29 age bracket are contacted, 213 respond and 35 refuse to respond. Assume that 1 of the 353 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who does not respond

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

it shoild be o

step-by-step explanation:

its 50 miles away from the starting point

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
