Answer:
66 inches
Step-by-step explanation:
1. Yards to Feet:
1 yard= 3 feet
(6 yards)(3)= 18
6 yards = 18 feet
2. Number of Groups:
30 students/6 students per group= 5 groups
3. Total String Needed:
(5 groups)x(2.5 feet string)= 12.5 feet total string
4. Remaining String:
18 feet-12.5 feet= 5.5 feet
5. Feet to Inches:
1 foot= 12 inches
(5.5 feet)(12)= 66 inches
66 inches of string will remain
Answer:
507
Step-by-step explanation:
For the Algebraic Expression,
let the two numbers be X and y
lets assume x = 217
From the question,
217 + y = 724
y = 724-217
y = 507
Therefore, the other number is 507
Answer:
La familia bebió:
2 botellas de 1.5 L = 2*1.5L = 3L
5 botellas de 1/4 de litro = 5*(1/4 L) = 5/4 L
4 botellas de 1/4 de litro = 4*(1/4 L) = 1 L
Sumando eso, tenemos:
3 L + (5/4) L + 1L = 4L + 5/4 L = (16/4) L + 5/4 L = (21/4) L.
21/4 Litros tomaron en total.

The correct interpretation of the standard deviation of the given discrete distribution is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
<h3>What are the mean and the standard deviation of a discrete distribution?</h3>
- The mean of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
- The standard deviation is the square root of the sum of the difference squared between each outcome and the mean, multiplied by it's respective probabilities.
Hence:
E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36

Hence the correct option is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
