Answer:
commutative property:
A + B = B + A
So we have
3 + (5 + 7) = (5 + 7) + 3
Now distributive means that:
A + (B + C) = (A + B) + C
So (5 + 7) + 3 = 5 + (7 + 3)
now the equation is easier to solve, because 7 + 3 = 10
5 + (7 + 3) = 5 + 10 = 15
Answer:
b
Step-by-step explanation:
64 = 2x^2
32 = x^2
x = 4√2
ans is b
g(x), the new function, is shifted down 4 from the original f(x)=2x-1
Shifting down 4 is negative, so it would be subtracting 4 from the original
g(x)= 2x-1 -4
g(x) = 2x-5
Answer:
The required probability is 0.55404.
Step-by-step explanation:
Consider the provided information.
The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typographical errors on a page of second booklet is a Poisson random variable with mean 0.3.
Average error for 7 pages booklet and 5 pages booklet series is:
λ = 0.2×7 + 0.3×5 = 2.9
According to Poisson distribution: 
Where
is average number of events.
The probability of more than 2 typographical errors in the two booklets in total is:

Substitute the respective values in the above formula.



Hence, the required probability is 0.55404.
Answer:
$4.5
Step-by-step explanation:
First, multiply 1.50 by 4 (since that how many friends there are)
1.5 * 4 = 6
Second, subract 24 by 6
24 - 6 = 18
Finally, divide 18 by 4
18 / 4 = 4.5
And there, the answer is $4.5. Hoped this helped :))
