Answer:
Step-by-step explanation:
1. Subtract 7 on both sides
2. multiply by 4 on both sides
3. v = 4
He can run 10.5 miles in 75 minutes
Answer:
0
Step-by-step explanation:
g(x) = x^2 - x - 2
Substitute x = 2:
g(2) = 4 - 2 - 2 = 0
Answer: a) 1,600
b) 35,000
c) 120,000
<u>Step-by-step explanation:</u>
First, round each number to one significant digit (the first digit).
Then multiply them.
a) 17 --> rounds to 20
82 --> rounds to 80
20 x 80 = 2 x 8 with two zeros
= 1 6 0 0
b) 54 --> rounds to 50
671 --> rounds to 700
50 x 700 = 5 x 7 with three zeros
= 3 5 0 0 0
c) 207 --> rounds to 200
643 --> rounds to 600
200 x 600 = 2 x 6 with four zeros
= 1 2 0 0 0 0
<span>A </span>continuity correction factor<span> is used when you use a continuous
function to approximate a discrete one. For example, when you want to
approximate a binomial with a </span>normal distribution<span>. According to the </span>Central Limit Theorem<span>, the </span>sample
mean<span> <span>of a
distribution becomes approximately normal if the </span></span>sample size<span> <span>is
large enough. The </span></span><span>binomial distribution </span><span>can be approximated with a </span>normal distribution<span> too, as
long as n*p and n*q are both at least 5. So the answer is large</span>
