Multiply the denominator by the whole number. Make that product the numerator. Let us now revisit the rule for changing a mixed number to an improper fraction<span> (Lesson 20).</span>
Answer:
Between 38.42 and 49.1.
Step-by-step explanation:
The Empirical Rule 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.
In this problem, we have that:
Mean of 43.76, standard deviation of 2.67.
Between what two values will approximately 95% of the amounts be?
By the Empirical Rule, within 2 standard deviations of the mean. So
43.76 - 2*2.67 = 38.42
43.76 + 2*2.67 = 49.1
Between 38.42 and 49.1.
Answer:
2
Step-by-step explanation:
Answer:
8.5E-12
Step-by-step explanation:
According to the Question,
Given That, The diameter of an insect cell is 1.7 × 10^-11 meters.
Ariel wants to find the length of the radius of the cell. Radius Is Half of the Diameter.
- Thus, R = D/2 ⇒ (1.7*10^-11)/2 = 0.85× 10^-11
- If she performs the calculations on her calculator is 8.5E-12.
