This one is best done by elimination:
We need to start 4 meters away, so B is clearly wrong.
We first move towards Mr. Wilson (i.e. distance is decreasing) so A is wrong.
Our speed is faster on the way back, so the two sloped section must have differing slopes, so D is wrong.
(D also doesn't start at 4, it's wrong for two reasons.)
Only C is left.
We can check each part to make sure. First we start at 4m, then move away, then stay still (zero slope) for three seconds, then move back faster (higher slope). All parts check out ok.
Answer:
-1/4
Step-by-step explanation:
2-1 over -3-1 = 1/-4
D. 82 Pairs
43+39= 82. therefore your answer is 82.

Answer:
The probability that exactly two of the four live in their own household and are income-qualified is = .0975
Step-by-step explanation:
Given -
Approximately 85% of persons age 70 to 84 live in their own household and are income-qualified for home purchases.
Probability of sucess ( p ) = 85% =.85
Probability of failure ( q ) = 1 - .85 =.15
n = 4
From combination of n events taking r sucess we use binomial distribution

where , r = 2
the probability that exactly two of the four live in their own household and are income-qualified is =

= 
= 
= .0975
Answer: 0.04 miles
SOLUTION
Given,
Average daily distance of a garden = 0.05 mile.
Distance traveled on day 1 = 0.2 times as far as the average
distance
= 0.2 x 0.05 miles
= 0.01 miles
Distance traveled on day 2 = 0.6 times as far as the average
distance
= 0.6 x 0.05 miles
= 0.03 miles
Total distance traveled in two days
= Distance traveled on day 1 + Distance traveled on day 2
= 0.01 miles + 0.03 miles
= 0.04 miles
