Answer:
x = 7/3
Step-by-step explanation:
4x - 2 = x + 3 + 2
4x - 2 = x + 5
Rearranging the terms, we get,
4x - x = 5 + 2
3x = 7
x = 7/3
Hence, x = 7/3.
Answer:
0.14
Step-by-step explanation:
Using the poisson probability relation :
P(x = x) = (λ^x * e^-λ) ÷ x!
From the question ; mean, λ = 5 ; x = 3
Hence,
P(x = 3) = (5^3 * e^-5) ÷ 3!
P(x = 3) = (125 * 0.0067379) / 6
P(x = 3) = 0.8422375 / 6
P(x = 3) = 0.140
Answer:
-3
Step-by-step explanation:
We want (n/p)(1). We can obtain this by finding n(1) and p(1) and then dividing as indicated:
p(1) = 3(1) - 2 = 1
n(1) = 2(1) - 5 = -3
Then (n/p) (1) = -3/1, or just -3
Answer: b=5
Step-by-step explanation:
7(b+2)=49
7b + 14= 49
7b = 49-14
7b= 35
b=35/7
b=5
8-3(p-4)= 2p
⇒ 8 -3p -3(-4)= 2p (distributive property)
⇒ 8 -3p+ 12= 2p
⇒ 8+12= 2p+3p
⇒ 20= 5p
⇒ 20/5= p
⇒ 4= p
Final answer: p=4~
