<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
Answer:
Explained Below
Step-by-step explanation:
200 people with those email addys might be people you know. While collecting addys randomly is a random sample.
its straight forward
Well you have to change the first number in ALL of the () so
(-1,1) = (1,1)
(-2,-1) = (2,-1)
(-1,0) = (1,0)
so your answer is d <span>(1, 1), B(2, -1), C(1, 0)</span>
Answer:
2 = $36, 3 = $54, 4 = $72
Step-by-step explanation:
Your constant is $18.
2 * 18 = 36
3 * 18 = 54
4 * 18 = 72
and so on..
Step-by-step explanation:
1. P(pen then pencil) = 15/25 × 10/25 = 3/5 × 2/5 = 6/25
2. P(pen then pencil) + P(pencil then pen) = 6/25 + 6/25 = 12/25
3. P(pencil then pencil) = 10/25 × 10/25 = 2/5 × 2/5 = 4/25
4. P(at least 1 pen) = 1 − P(no pen) = 1 − 4/25 = 21/25
