9,200 contains 92 hundreds.
Explanation:
One hundred can go into 9200 92 times
(9,200 % 100)
I use simple annual interest to solve the problem
<span>$125.37 -------------------------------- 3 years
X-------------------------------------------> 1 year
X=125.37/3=</span>$41.79/ year
<span>$597--------------------->100%
</span>$41.79---------------------X%
X=41.79*100/597=7%
The rate was 7%
Check the picture below.
since we know the endpoints of the diameter of the circle, then we can simply get the midpoint of those endpoints and that'd be the center,
Answer:
x = 20
Step-by-step explanation:
given f(x) = 
, we have to solve
= 4
Square both sides
()² = 4²
x - 4 = 16 ( add 4 to both sides )
x = 20
As a check
= 
= 4 ← correct
Answer:
0.85083 ; 0.83147 ; 0.6823 ; 0.015386
Step-by-step explanation:
Given that:
σ = 25
μ = 86
(a) x is more than 60
P(x > 60)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (60 - 86) /25
Z = - 1.04
P(Z > - 1.04) = 0.85083 (Z probability calculator)
(b) x is less than 110
P(x < 110)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (110 - 86) /25
Z = 0.96
P(Z < 0.96) = 0.83147 (Z probability calculator)
(c) x is between 60 and 110
P(x < 110) - P(x < 60)
P(Z < 0.96) - P(Z < - 1.04)
0.83147 - 0.14917
= 0.6823
(d) x is greater than 140
P(x > 140)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (140 - 86) /25
Z = 2.16
P(Z > 2.16) = 0.015386 (Z probability calculator)
