Step-by-step explanation:
The volume of the cylinder is
V2 = (pi)r^2L
= (3.14)(12.5 xm)^2(50 cm)
= 24531.3 cm^3
The volume of the half cylinder is
V3 = (1/2)(24531.3 cm^3)
= 12265.7 cm^3
If V1 is the volume of the prism then the total volume of the storage chest is
V = V1 + V2 + V3
= 37500 cm^3 + 24531.3 cm^3 + 12265.7 cm^3
= 74297.0 cm^3

Which set of data has the smallest difference between the mean and the median?
O A 13, 42, 17, 26, 38
OB. 28, 7, 36, 8, 17
OC 14, 29, 38, 7, 13
OD 23, 36, 25, 38, 30
Answer:
D 23, 36, 25, 38, 30
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is the sum of all it's values divided by the number of values.
Median of a data-set:
The median of a data-set is the value that separates the lower 50% from the upper 50% on the ordered set.
If the cardinality n is odd, as in this case, the median is the element at the position (n+1)/2. Since in this case, n = 5, the median is the 3rd element in the ordered set.
A 13, 42, 17, 26, 38
Ordered set: 13, 17, 26, 38, 42
Median: 26
Mean: (13+17+26+38+42)/5 = 27.2
Difference: 27.2 - 26 = 1.2
B. 28, 7, 36, 8, 17
Ordered set: 7, 8, 17, 28, 36
Median: 17
Mean: (7+8+17+28+36)/5 = 19.2
Difference: 19.2 - 17 = 2.2
C 14, 29, 38, 7, 13
Ordered set: 7, 13, 14, 29, 38
Median: 14
Mean: (7+13+14+29+38)/5 = 20.2
Difference: 20.2 - 14 = 6.2
D 23, 36, 25, 38, 30
Ordered set: 23, 25, 30, 36, 38
Median: 30
Mean: (23+25+30+36+38)/5 = 30.4
Difference: 30.4 - 30 = 0.4

using appropriate properties find 9/16×4/12+9/16×-5/9
Answer:
-1/8
Step-by-step explanation:
Given 9/16×4/12+9/16×-5/9
Using the PEMDAS rule;
Multiplication first
(9/16×4/12)+(9/16×-5/9)
= 3/4 * 1/4 + -5/16
= 3/16 - 5/16
= (3-5)/16
= -2/16
= -1/8
Hence the required answer is -1/8
suppose that a population parameter is 0.2, and many samples are taken from the population. As the size of each sample increases, the mean of the sample proportions would approach which of the following values?
A. 0.1
B. 0.3
C. 0.4
D. 0.2
Answer:
D 0.2
Step-by-step explanation:
YES THIS IS RIGHT
The required, mean of the sample proportions would approach is 0.2.
What is a normal distribution?Normal distributions can be altered to standard normal distributions by the formula:
Z = (X - μ)/σ
As the size of each sample increases, the mean of the sample proportions would approach the population parameter, which in this case is 0.2. This is known as the central limit theorem.
Therefore, the answer is D. 0.2.

Step-by-step explanation:
Why 117+3 = 5! is correct
Answer:
5!= 5×4×3×2×1
117+3=120
5×4×3×2×1= 120
therefore 117+3=5! is correct
The statement 117+3 = 5! is correct because;
The left hand side and right hand side give the same solution of 120.
We want to find out why 117 + 3 = 5! is correct.
Let us first find the left hand side of the equation;
117 + 3 = 120
Now, for the right hand side, 5! simply means 5 factorial.
Factorial of a number is a term used in maths to denote the product of all
positive integers less than or equal to that number. For example; n!. That is
factorial and it means the product of all positive integers below n.
Let's apply the concept of factorial to 5!.
All positive integers less than or equal to 5 are; 5, 4 , 3, 2, 1
Thus; 5! = 5 × 4 × 3 × 2 × 1 = 120
This 5! = 120 and it is the same as 117 + 3 = 120. Thus the given statement in the question is true.

Assume that the lives of all such bulbs have a normal distribution with a mean of hours and a standard deviation of hours. Find the probability that the mean life of a random sample of such bulbs will be
Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
Probability that the mean life of a random sample of 25 bulbs will be less than725 hours
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )
