Answer:
12x -y = -87
Step-by-step explanation:
You can start with the 2-point form of the equation of a line and manipulate it to give you the standard form.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-9 -3)/(-8 -(-7))(x -(-7)) +3
y = (-12/-1)(x +7) +3
y = 12x +84 +3
-12x +y = 87 . . . . . subtract the x-term
12x -y = -87 . . . . . . make the leading coefficient positive (per standard form)
Using the probability concept, it is found that:
a) P(girl) = 1/3, which means that 1/3 = 33% of the time, the first batter will be a girl.
b) P(boy) = 2/3, which means that 2/3 = 67% of the time, the first batter will be a boy.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, in a total of 15 people, 5 are girls and 10 are boys, hence:

Answer:
556 ft²
Step-by-step explanation:
The given information is,
→ Length (l) = 11 ft
→ Breadth (b) = 10 ft
→ Height (h) = 8 ft
Formula we use,
→ 2(lb + bh + lh)
The surface area of cuboid will be,
→ 2(lb + bh + lh)
→ 2{(11 × 10) + (10 × 8) + (11 × 8)}
→ 2(110 + 80 + 88)
→ 2 × 278
→ [ 556 ft² ]
Therefore, the TSA is 556 ft².
Answer:
26190 meters
Step-by-step explanation:
The distance moved by a glacier = 29.1 meter per day
For 100 days, the distance moved = 29.1 meter per day * 100 days = 2910 meters
For 1000 days, the distance moved = 29.1 meter per day * 1000 days = 29100 meters
Therefore the distance farther it move in 1,000 days than it will move in 100 days = distance moved in 1000 days - distance moved in 100 days
farther distance = 29100 meters - 2910 meters = 26190 meters
