I'm assuming the question is referring to a game of skee ball or something similar. In this case, there are many holes in the scoring area, and the probability of landing in the 40 point hole would be the area of the hole divided by the area of the entire scoring zone. Therefore:
1.) If the size of the 40 point hole is enlarged, the probability: INCREASES
This is because the hole now takes up more of the total area.
2.) If the 40 point hole is made smaller the probability: DECREASES
This is because the hole now takes up less of the total area.
3.) If the 40 point hole stays the same size but the scoring zone is made smaller, the probability: INCREASES
This is because there is less total area, which in turn means that the hole which was not changed now takes up a larger percentage of the scoring zone.
In the given equation above relating the number of races the runner had run and the finishing time,
f = -1.2n + 38.1
It can be deduced that the initial finishing time is approximately 38.1 and that the time is reduced by 1.2 minutes in every race that the runner had run. Therefore, the answer to this item is letter B.
Answer:
The sum of two angles is 180.
x + y = 180
The measure of one angle is 34 greater than the measure of the other angle.
x - y = 34
=> 2x = 214
=> x = 107 deg
=> y = 107 - 34 = 73 deg
Hope this helps!

Answer:
speed of car A =Speed of car B=0.8 miles/minutes.
Step-by-step explanation:
We are given that speed of car A is equal to speed of car B.
Also let car A travels x miles.
and car B travels y miles.
Car A reaches its destination in 17 minutes.
this means that speed of car A is given by: 
miles/minutes ( since speed is defined as the ratio of distance and time).
Car B reaches its destination in 32 minutes.
This means that the speed of car B is given by: 
miles/minutes
as speed of both cars are equal this means:
------(1)
Also we are given Car B travels 12 miles farther than Car A.
this means 
------(2)
on using equation (1) and (2) we have:
Hence the speed of car A is 0.8 miles/minutes ( since x/17 is the speed of car A)
Speed of car B=0.8 miles/minutes.
