Answer:
0.265
Step-by-step explanation:
Given that :
Number of flaws per mm follows a poisson distribution:
Mean flaws per mm (x) = 2.3
Probability of exactly two flaws in 1 mm of wire
P(X = 2) = (x² * e^-x) / x!
P(x = 2) = (2.3² * e^-2.3) / 2!
P(x = 2) = (5.29 * 0.1002588) / 2
P(x = 2) = 0.265

Which inequality would result in the shaded solution on the unit circle to the right?
The inequality that would result in the shaded solution on the unit circle to the right is [tex]\cos(x)>\sqrt{3}/2[/tex] and this can be determined by using the trigonometric properties.
Given :
The unit circle is given.
The following steps can be used in order to determine the inequality that would result in the shaded solution on the unit circle to the right:
Step 1 - First determine the value of cosine function when the angle is [tex]5\pi/6[/tex]
[tex]\cos\dfrac{5\pi}{6} = -\cos \dfrac{\pi}{6}[/tex]
[tex]\cos\dfrac{5\pi}{6} = -\dfrac{\sqrt{3} }{2}[/tex]
Step 2 - Now, determine the value of the cosine function when the angle is [tex]\pi/6[/tex].
[tex]\cos\dfrac{\pi}{6} = \dfrac{\sqrt{3} }{2}[/tex]
Step 3 - Now, when the value of 'x' increases then the value of the cosine function also increases.
From the above steps, it can be concluded that the cosine function should be greater then [tex]\sqrt{3} /2[/tex]. Therefore, the correct option is A).

Edward solved the equation 4X + 1 = 5x +(-5)
Add 4 negative both sides
Add 5 negative to both side
=4
What’s was mistake
Answer:
He should have added 5 to each side instead of -5
Step-by-step explanation:
4X + 1 = 5x +(-5)
Subtract 4x from each side
4X-4x + 1 = 5x-4x +(-5)
Combine like terms
1 = x-5
Add 5 to each side
He should add 5 to each side ( we need to add the opposite of (-5)) to undo the adding of (-5)
1+5 = x-5+5

If a car is traveling 75 miles per hour, how many feet will it travel in 10 seconds ?
If 1 mile= 5280 feet, So If a car is traveling 75 miles per hour, then it is travelling 1100 feet in 10 seconds.
What is 1 mile in ____ feet?1 mile= 5280 feet
A car is traveling 75 miles per hour, we need to find how many feet it travel in 10 sec.
1 hour = 60*60 = 3600 seconds
75 miles: 1 hour
75 miles: 3600 seconds
75/3600 miles: 3600/3600 seconds
1 second: 1/48 mile
1/48 miles = (1/48)*5280 = 110 feet
So you're going 110 ft per second. In other words, the car travels 110 feet in 1 second.
For 10 seconds 110*10=1100.
Therefore 1100 feet will car travel in 10 seconds.

NEED HELP ASAP, VIEW THE PHOTO FOR THE QUESTION PLZ I NEED HELP
Answer:
x=0 is the solution
Step-by-step explanation:
Notice that the graph is that of a parabola with vertex at the point (0, 0).
When we solve for x in the equation:
- x^2 = 0
then we divide by -1 both sides an get: x^2 = 0/(-1) = 0
and finally use the square root property to find the answer and we get:
[tex]x=+/- \sqrt{0} = +/- 0 = 0[/tex]
Since +0 = - 0 (this is the null value), there is only one solution: x = 0.

You are buying a new bicycle. The table shows the prices of bicycles at a store. You are willing to pay the mean price with an absolute deviation
of at most $60.
Select which inequalities represent the prices you are willing to pay.
Bicycle prices:
$350 $450 $180 $200
$290 $325 $240 $445
x-60 S 310
| x + 60 < 310
1 x + 310 < 60
x < 250 or x > 370
X - 310 < 60
250 < x < 370
Answer:
250 < x < 370
Step-by-step explanation:
From the given bicycle prices, we first calculate the mean.
Mean = ⅛($350 + $450 + $180 + $200 + $290 + $325 + $240 + $445)
Mean = ⅛(2480)
Mean = $310
Next, is to determine the amount willing to pay using.
Amount = Mean ± Absolute Deviation
Amount = $310 ± $60
This can split as follows
Amount = $310 + $60 or Amount = $310 - $60
Amount = $370 or $250
Represent as an inequality, we have:
250 < x < 370
Compare the proportional relationships. Which represents the greatest price per pound of walnuts
Answer:
B. Weight
Price
The price per pound of walnuts is the slope or unit rates of the graphs, lines and equations
The greatest price per pound of walnuts is $14.00
(a) Cost of 1.5 bags is $12.99
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{Cost}{Bags}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{\$12.99}{1.5}}[/tex]
[tex]\mathbf{Rate = \$8.66}[/tex]
The price per pound of walnuts is $8.66
(b) The table
From the table, we have the following points
[tex]\mathbf{(x,y) =(0.2,2.80)\ (0.4, 5.60)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{5.60 - 2.80}{0.4 - 0.2}}[/tex]
[tex]\mathbf{Rate = 14}[/tex]
The price per pound of walnuts is $14.00
(c) The graph
From the table, we have the following points
[tex]\mathbf{(x,y) =(0,0)\ (1, 11)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{11 - 0}{1 - 0}}[/tex]
[tex]\mathbf{Rate = 11}[/tex]
The price per pound of walnuts is $11.00
By comparison, the greatest price per pound of walnuts is $14.00

There are 4 blue and 6 red marbles in a box. Two marbles are drawn at random without replacement. What is the probability having two blue marbles drawn?
Answer:
Probability having two blue marbles(Without replacement) = 2/15
Step-by-step explanation:
Given:
Number of blue marble = 4
Number of marble = 6
Find:
Probability having two blue marbles(Without replacement)
Computation:
Probability of first marble = 4 / 10
