Answer: 0.6
Step-by-step explanation:
0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
Nuan is using a faulty barcode scanner that misreads barcodes 5% of the time.
Let B = the number of barcodes Nuan scans until the scanner misreads one.
n=10
p=5%=0.05
Mean=1/p=1/1/20=20
Variance=1-p/p²
=1-1/20/(1/20)²
=19/20×400
=380
Standard deviation=√380=2√95=19.493
p(x=10)=0.0315
p(x<10)=0.3697
p(x≤10)=0.40126
p(x>10)=0.598
=0.6
Hence, 0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.

Use the Pythagorean Theorem to solve for the missing side length. Round to the nearest tenth if necessary.
a = 8 b = c = 10
Answer:
B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
answer: B= 6

Which expressions are equivalent to 1/2+3c+4/5?Check all that apply.
Answer: A, C and E.
Step-by-step explanation:
The expressions 1/2 + 3c + 4/5 is thesame as writing 3c + 1/2 + 4/5, 1/2 + 4/5 + 3c, 4/5 + 1/2 + 3c, 3c + 1/2 + 4/5.
In all the expressions written above, the only thing that can be seen is just that the position of the numbers were alternated.
Therefore, based on the options given, the answer will be A, C, and E.

The graphs of rational functions m and n have the same vertical asymptotes, and both have a single x-intercept at x = 5.
Which equation could represent function n?
A.
n(x) = 5m(x)
B.
n(x) = m(x) + 5
C.
n(x) = m(x − 5)
D.
n(x) = m(x + 5)
Answer:
A
Step-by-step explanation:
We are given two rational functions m(x) and n(x) that have the same vertical asymptotes both with a single x-intercept at x = 5.
The correct choice will be A.
Recall the transformations of functions.
B represents m(x) being shifted up 5 units. If the function is shifted up, the vertical asymptotes will be the same, but the x-intercept will change.
C represents m(x) being shifted 5 units to the right. This changes both the x-intercept and the vertical asymptotes.
Likewise, D represents m(x)being shifted 5 units to the left. Again, this will change both the x-intercept and the vertical asymptotes.
Therefore, the only choice left is A. It represents a vertical stretch by a factor of 5. This preserves the x-intercepts and the vertical asymptotes. Consider, as an example, the function:
[tex]\displaystyle m(x)=\frac{x-5}{(x-3)(x-7)}[/tex]
If n(x)=5m(x), we can see that:
[tex]\displaystyle n(x)=\frac{5(x-5)}{(x-3)(x-7)}[/tex]
So, the x-intercepts and vertical asymptotes are preserved.

Alison's dog is 6 pounds more than five times the weight of gales dog what algebraic equation could you make to find G which is the way to gail's dog.
Answer:
g = (x - 6) / 5
Step-by-step explanation:
Given:
Let :
Alison's dog = x
Gale's dog = g
x is 6 pounds more than 5 times g
Mathematically,
x = 5g + 6
We can solve for g ;
x - 6 = 5g
Divide both sides by 5
(x - 6) / 5 = g

9514 1404 393
Answer:
x = 45
Step-by-step explanation:
If we assume that ray GJ lies between rays GF and GH, then the angle sum theorem tells us ...
∠FGH = ∠FGJ +∠JGH
140° = 95° +x°
45° = x° . . . . . . subtract 95° from both sides
x = 45
_____
Alternate solution
There is an alternate solution if ray GF lies between ray GH and ray GJ.
∠JGH = ∠FGJ +∠FGH
x° = 95° +140°
x° = 235°
x = 235
Without some additional information, we cannot tell which assumption we should make about the geometry.

Why is the point (12, 780) significant on the graph of the functions representing these three salesmen? Use complete sentences to explain your reasoning.
Answer:
Hope this helps 0>0
Step-by-step explanation:
Let x represent the number of sales each man had.
For Salesman A, he earns $65 per sale; this is 65x.
For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.
Since their pay was equal, set the two expressions equal:
65x = 40x+300
Subtract 40x from each side:
65x-40x = 40x+300-40x
25x = 300
Divide both sides by 25:
25x/25 = 300/25
x = 12

cm?
Answer:
12 square centimeters
Step-by-step explanation:
Not sure what formula you are using here. The standard one is A=1/2 b h, where b is the base and h is the height.
base=4
height=6
A= 1/2 x 4 x 6
A=1/2 x 24
A=12 cm^2
