Answer:

Step-by-step explanation:
1. Subtract 10 from both sides. Then:

2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:

3. Add 22 to both sides. Then:

4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:

5. Subtract 30 from both sides. Then:

6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:

7. Subtract 13 from both sides. Then:

8. Add 12 to both sides. Then:

when coin is flipped 5 times probability is 1/2
so coin heads comes out to be 2.5
This is a binomial distribution with a probability of success = 0.5 (fair coin).
n=10
so
mean = E[x] = np =10*0.5 =5
3.8 / 1.9 = x / 7.6....3,8 miles to 1.9 miles = x miles to 7.6 miles
cross multiply
(1.9)(x) = (3.8)(7.6)
1.9x = 28.88
x = 28.88 / 1.9
x = 15.2 <== Cameron ran 15.2 miles
Answer:
and 
Step-by-step explanation:
Alright, lets get started.
The given equation is :

Adding 8 in both sides, it will become


To make it perfect square, we need to add 25 and subtract 25




Adding 17 in both sides
taking square root

So,
and
