If the 4x2 is actually 4x^2 then the answer is
-(4x+3x-24)
Answer:
0.26684
Step-by-step explanation:
Given that :
Mean, μ = 62.5
Standard deviation, σ = 1.96
P(Z ≥ 63.72)
The Zscore = (x - μ) / σ
P(Z ≥ (x - μ) / σ)
P(Z ≥ (63.72 - 62.5) / 1. 96) = P(Z ≥ 0.6224)
P(Z ≥ 0.6224) = 1 - P(Z < 0.6224)
1 - P(Z < 0.6224) = 1 - 0.73316 = 0.26684
2r2+2r−24=0
Step 1: Factor left side of equation.
2(r−3)(r+4)=0
Step 2: Set factors equal to 0.
r−3=0 or r+4=0
r = 3 or r = −4
I feel that it is 5.5%/ 0.055
Process:
8.00*5.5%/ 0.055=0.44
8.00+0.44=8.44
10.00-8.44=1.56
Square root of 9 is 3
Square root of 4 is 2
so 3/2
Make it negative and you got -3/2 for your answer.
