4 heads, 4 tails, 3 heads one tails, one heads 3 tails, 2 heads 2 tails
so 5 outcomes I believe
Answer: 140
Step-by-step explanation:
Angles 3 and 4 have equivalent degree values. Set them equal to each other: x + 30 = 2x - 80
Solve for x: add 80 to both sides
x + 110 = 2x
Then subtract x from both sides
110 = x. This is x, not the final answer. The question asks for the measure of angle 3.
To get the measure of angle 3, plug in 110 for x.
Instead of x + 30, calculate 110 + 30.
So, angle 3 is 140 degrees.
Answer:
15 students were on each bus.
Step-by-step explanation:
100 students have gone a field trip, 10 have travelled with their parents. So, you would do 100-10 to get 90. 90 students are riding the buses. To get the amount of students on each buses, you have to do 90÷6 to get 15.
Answer:
d(apart are the ships)=42.8 meters
Step-by-step explanation:
Given data
h (height)=38m
Ф₁=53°
Ф₂=28°
d(how far apart are the ships)=?
Solution
d₅₃°(distance to ship at 53°)=h/tanФ₁
d₅₃°=38/tan(53°)
d₅₃°=28.6m
now
d₂₈°(distance to ship at 28°)=h/tanФ₂
d₂₈°=38/tan(28°)
d₂₈°=71.4m
d(apart are the ships)=d₂₈°-d₅₃°
d(apart are the ships)=71.4-28.6
d(apart are the ships)=42.8 meters
Answer:
Linear
Step-by-step explanation:
First, calculate the rate of change between each point. Finding this will tell us what type of equation it is.
The formula we will need to use is 
Let's start with (-2, 1) and (-1, 3).
The rate of change between these first two points is 2. Now, let's find the rate of change between (-1, 3) and (0, 5)
The rate of change between these two points is also 1. When this happens, we know that the line straight.
Linear is just another way to say straight, so this equation is linear.
We know it's not quadratic because if it were, then the rate of change would be gradually increasing or decreasing.
Testing the rate of change of just two points is enough to know that it is linear.
