By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
<h3>What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches?</h3>
According to the empirical rule :
(1) 68% of the measures should come within 1 standard deviation of the mean.
(2 95% of the measures should come within 2 standard deviations of the mean.
(3) 99.7% of the measures should come within 3 standard deviations of the mean.
So we can see in this problem
The mean is 7 inches.
The standard deviation is 1.2 inches.
4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Answer:
5/2
Step-by-step explanation:
The multiplicative inverse is what me need to multiply by to get 1
2/5 * what = 1
Multiply by the reciprocal
5/2 *2/5 * what = 1 *5/2
what = 5/2
The multiplicative inverse is 5/2
Answer:
3 ft = 36 in
8 yd = 24 ft
Step-by-step explanation:
1 ft = 12 in, 3 ft = 36 in
1 yd = 3 ft, 8 yd = 24 ft
