Answer:
85
Step-by-step explanation:
<em>The equation for the discriminant is </em>
b^2-4(a)(c)
<em>Plug your numbers in from the equation. </em>
<em>1=a, -7=b, -9=c</em>
<em />
(-7)^2-4(1)(-9)
49-(-36)
49+36

Why is the question like that
Answer:
0.0374722
Step-by-step explanation:
Given that :
μ = 52
x = 58
P(x, μ) = (e^-μ) * (μ^x)/ x!
P(58, 52) = ((e^-52) * (52^58)) / 58!
P(58, 52) = [(2.6102E−23 * 3.37437E99) / 2.35056E78]
P(58, 52) = 8.80807E76 / 2.35056E78
P(58, 52) = 0.0374722
Answer:
Mistake in Line 2
Step-by-step explanation:
Line 1
7(6) ÷ 5 + 42
Line 2
7(6) ÷ 5 + 16
Line 3
42 ÷ 5 + 16
Line 4
42 ÷ 21
Line 5
2
To simplify any expression we use order of operation
Line 1 is 7(6) ÷ 5 + 42
Order of operation is PEMDAS
First we start with parenthesis
so we multiply 7(6) in line 2
7*6- 42
So Line 2 is 42 ÷ 5 + 42
Hence there is a mistake in Line 2
