The print on the package of -watt General Electric soft-white light-bulbs says that these bulbs have an average life of hours. 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

Answers

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 )

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

Answers

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

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

Petra is making necklaces to sell at a craft fair. The hardware for each necklace costs $3.75,
and each bead costs $0.50. The number of beads Petra needs depends on the design she
chooses. Which expression gives the total cost to make 30 necklaces with b beads?
30 (4.25b)
30 (3.75b + 0.5)
30 (0.55 +3.75)
30 (0.5b) + 3.75

Answers

the answer would be 30(0.5b)+3.75 i think because .50 would have to have a variable since we don’t know the number of beads.

Why 117+3 = 5! is correct

Answers

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.

A. 0.1
B. 0.3
C. 0.4
D. 0.2

Answers

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.
