The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. If there are 461 households in the community, about how many of them have electric bills less than $200?
A. 45
B. 21
C. 95
D. 81
95 households have electricity bills of less than $200. Option C is correct.
Given that,
The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. There are 461 households in the community, how many of them have electric bills less than $200 is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
probability for the number of households has electric bills less than $200.
x = 200 , μ = 245 ; σ = 55
Now,
Probability,
z (p < 200) = [tex]\frac{X -\mu}{\sigma}[/tex]
z (p < 200) = (200 - 245)/55
= --45/5
= -0.818181
p < 200 = 0.206 (from z table)
Now, the number of households that has electricity bill less than $200,
= 461 * 0.206
= 94.966
≈ 95
Thus, 95 number of household have electricity bills of less than $200. Option C is correct.

If using the method of completing the square to solve the quadratic equation
x2 – 9x + 38 0, which number would have to be added to "complete the
square"?
=
Answer:
81/4
Step-by-step explanation:
Given the equation x^2 – 9x + 38 = 0
Subtract 38 from both sides
x^2 – 9x + 38 - 38= 0 - 38
x^2 - 9x = -38
Next is to complete the square, to do this we will add the square of the half of coefficient of x to both sides as shown;
Coefficient of x is - 9
Half of -9 will be (-9/2)
Squaring the result will give (-9/2)² = 81/4
Hence the number that would have to be added to "complete the
square" is 81/4 to have;
x^2 - 9x + 81/4= -38 + 81/4
(x-9/2)² = -38 + 81/4
Hence the required value is 81/4
Define confidence interval and degree of confidence. Provide at least one example of a confidence interval and interpret the result.
Answer:
confidence interval:
This tells us the degree of certainty or uncertainty that is existent in a sampling method. It gives us a range of values, telling us we are fairly sure that our true value or parameter lies within the range.
Degree of confidence:
This tells us that the confidence interval has captured the true/exact population parameter.
If we have 95% degree of confidence, we are 95% sure that that the exact/true parameter are in the confidence interval

−6x + 6y = 6 −6x + 3y = −12
Answer:
x = 0
y = 2
Step-by-step explanation:
−6x + 6y = 6 −6x + 3y = −12
-6x+6x+6y-3y = 6
3y = 6
y = 2
checking:
6-6x+3.2 = -12
6-6x+6 = -12
12-6x = 12
x = 0
checking 2:
since x = 0 we ignore it and its multipliers from the equation:
6y=6+3y = 12
6.2 = 12 (check)
6+3.2 = 12
6+6 = 12 (check)
Write an expression that is equivalent to 27e + 24.
Answer:
3 (9e + 8)
explanation:
3 x 9e = 27e
and
3 x 8 = 24
Both are multiplyed by 3 so your first number is
3 ( ?e + ?)
then the 2ed has e beside so i know thats 9
3 ( 9e + ?)
The final one is 8. 3 x 8 = 24 so there is 24 in the question so the last is 8
3 (9e + 8)
3(9e+8) is the expression that is equivalent to 27e + 24.
What is Expression?An expression is combination of variables, numbers and operators.
We need to find the equivalent fraction of 27e + 24.
For this let us find the factors of 27 and 24
Factors of 27 are 1,3,9,27
Factors of 24 are 1,2,3,4,6,8,12,24
The greatest common factor is 3.
So in the expression 27e+24 take 3 as common
3(9e+8)
Hence 3(9e+8) is the expression that is equivalent to 27e + 24.

Paula ran 3 1/4 kilometers. Omar ran 4,200 meters. Who ran farther and by how much?
Answer:
Omar ran farther
Step-by-step explanation:
Paula ran 3250 meters and Omar ran 4200 meters. Omar ran 950 more meters than Paula
omar because 3 1/4 meters is the same as 3250 meters so then
4200>3250 so omar did more
which is equivalent to the expression 2/3(d + 6)
