Answer:
7.1 weeks to 68.4 weeks
Step-by-step explanation:
Chebyshev's Theorem states that:
75% of the measures are within 2 standard deviations of the mean.
89% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 38.1
Standard deviation = 10.1
Between what two search times does Chebyshev's Theorem guarantee that we will find at least 89% of the graduates
Between 3 standard deviations of the mean.
So from 38.1 - 3*10.1 = 7.8 weeks to 38.1 + 3*10.1 = 68.4 weeks
256 = 16^2. In turn, 16=4^2.
The 4th roots are {4, 4, -4 and -4}.
Check for yourself: Does 4^4= 256? does (-4)^4 = 256?
Answer:
equation :
1. b + 5 = 3
2. 3b = - 6
3. 10b = -20
1. b = 3 - 5 = - 2
2. 3b/3 = - 6/3 = - 2
3. 10b / 10 = - 20 / 10 = - 2
Answer:
m=-5
Step-by-step explanation:
You first do distributive property:
(-m*-1)+(-1*-7)+(-3*4m)+(-3*-3)=71
that simplifies to:
16-11m=71
Next subtract 16 on both sides and you get:
-11m=55
Then divide by -11,
m=-5
