73 cm, the perimeter is all side totals, to to find each side length you just have to divide by 4 since all the sides of a square are the same
Answer:
7k
Step-by-step explanation:
−k−(−8k) = -k +8k = 7k
Answer:
:))
Step-by-step explanation:
Using the Empirical Rule, it is found that the lifespans, in months, are given by:
1. 24 and 32.
2. 20 and 36.
3. 16 and 40.
<h3>What is the Empirical Rule?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Hence, considering the mean of 28 months and the standard deviation of 4 months, the life spans are given by:
1. 24 and 32.
2. 20 and 36.
3. 16 and 40.

Answer: Assuming that it's already in the standard form - y=mx+b | Your Y-Intercept is going to be -9
Step-by-step explanation:
Using the equation y=mx+b, anything that is in place of the (b) is your Y-Intercept and your slope is (m)
