Answer:
1 - p(7 girls) = 1 - 0.483^7 = 0.9939
The answer would be -74,137,498.67 when you follow the order of operations. (PEMDAS).
Let's define what as 'x'
3x = 75
Divide both sides by 3.
3x/3 = 75/3
x = 75/3
x = 25
Three times twenty five equals 75.
Your final answer is twenty five or 25.
Answer:
Makenzie is correct, 13.93 ≈c
Step-by-step explanation:
the sides with determined lengths (see image) are A (13) and B (5). C however is not determined.
the correct equation would be to solve for c.
13² + 5² = c²
c ≈ 13.93
Clara solved for b and not c, which is incorrect.
Answer:
x = 1
y = 5
Step-by-step explanation:
You can use either substitution or elimination for this problem. I will use substitution.
Step 1: Replace x in the 1st equation
-10(y-4) + 3y = 5
-10y + 40 + 3y = 5
-7y = -35
y = 5
Step 2: Plug <em>y </em>into an original equation to find <em>x</em>
x = 5 - 4
x = 1
And you have your final answers!
