Answer:
B. lie on different lines
Step-by-step explanation:
B=A the are the same angle B and A
Answer:
Between 38 and 86 months.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
In this question:
Mean of 62, standard deviation of 12.
Between what two lifetimes does Chebyshev's Theorem guarantee that we will find at least approximately 75% of the computers?
Within 2 standard deviations of the mean, so:
62 - 2*12 = 38
62 + 2*12 = 86
Between 38 and 86 months.
Answer:
Step-by-step Solution:
<u>We know that:</u>
- 55 = 5x + 15 (Vertically opposite angles)
<u>Solution:</u>
- 55 = 5x + 15
- => 55 - 15 = 5x
- => 40 = 5x
- => x = 8
Hence, the value of x is 8.
X+ (x+2)+ (x+4)= -21
3x+6=-21
3x=-27
x=-9
Final answer: -9, -7, -5
