Step-by-step explanation:
two percent of a product are defective. if a lot of 100 items are ordered what's the probability that there are no defective item? what's the probability that there are at least two defective items?
Answer:
P(X ≥ 2) = 0.5967
Step-by-step explanation:
Using binomial probability distribution formula;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
two percent of a product are defective. Thus; p = 0.02
a lot of 100 items are ordered. Thus, n = 100
Probability that there are no defective items is;
P(X = 0) = C(100, 0) × 0.02^(0) × (1 - 0.02)^(100 - 0)
P(X = 0) = 0.98^(100) = 0.1326
the probability that there are at least two defective items will be;
P(X ≥ 2) = 1 - P(X < 2)
Now,
P(X < 2) = P(X = 0) + P(X = 1)
P(X = 1) = C(100, 1) × 0.02^(1) × (1 - 0.02)^(100 - 1)
P(X = 1) = 100 × 0.02 × 0.98^(99) = 0.2707
Thus;
P(X < 2) = 0.1326 + 0.2707
P(X < 2) = 0.4033
P(X ≥ 2) = 1 - 0.4033
P(X ≥ 2) = 0.5967
Which Inequality is shown on the accompanying graph (image included)
If you can, pls explain :’)
Answer:
4. x ≥ -1
Step-by-step explanation:
The graph shows a directed line that starts at -1 towards the your right. The full circle indicates that -1 is included among the possible values of x. This means that all possible values of x include -1 and above.
Therefore, we can say x is greater than or equal to -1.
This is represented as:
x ≥ -1
can someone explain how 1/4 × 900/1 is equal to 225, my mom is asking for an explanation and I used a calculator help me
Answer:
See below
Step-by-step explanation:
[tex] \frac{1}{4} \times \frac{900}{1} \\ \\ = \frac{1 \times 900}{4 \times 1} \\ \\ = \frac{900}{4} \\ \\ = \frac{9 \times \cancel {100} }{\cancel4} \\ \\ = 9 \times 25 \\ \\ = 225[/tex]
Answer:
four of 225 makes 900/1, or 900. So, one 225 should be one of the four 225s that equal 900. 1/4 × 1/900, or 1/4 of 900, should be 225.

Point BStep-by-step explanation:
-6 is to the left from origin and π/12 is in between 0 and π/6 above the x-axis. So the point (-6, π/12) is in the second quadrant.
Other points represent coordinates of:
A=(6, π/12), C=(-6, -π/12), D=(6, -π/12)This is point B and correct choice is option B.
9514 1404 393
Answer:
point C
Step-by-step explanation:
The given coordinates (-6, π/12) are equivalent to (6, 13π/12). That is, the negative radius is equivalent to a positive radius in the opposite direction (angle different by π radians).
The point on the diagram with coordinates (6, 13π/12) is point C.

Ron flies his airplane 20 km over the ground. He gains 800 m in altitude over the flight. What is the slope of the line segment representing the flight.
Answer:
this might help.......
Step-by-step explanation:
...
The slope of the line segment representing the flight is 0.04.
The slope of a line segment is calculated by dividing the change in the vertical direction (the altitude) by the change in the horizontal direction (the distance traveled). In this case, the change in the vertical direction is 800 meters (800 / 1000 = 0.8 kilometers) and the change in the horizontal direction is 20 kilometers. Therefore, the slope of the line segment is 0.8 / 20 = 0.04.
In other words, for every kilometer that Ron travels, he gains 4 meters in altitude.
Here is the solution in more detail:
Define the variables.
x: The distance traveled in kilometers.
y: The altitude in meters.
Write the equation for the line segment.
The slope of the line segment is 0.04, so the equation for the line segment is y = 0.04x + b.
We know that when x = 0, y = 0, so b = 0.
Substitute the known values into the equation.
We know that x = 20 and y = 800, so we can substitute these values into the equation to get 800 = 0.04 * 20 + 0.
Simplifying the right side of the equation, we get 800 = 0.8.
Solve for the slope.
The slope is 0.8 / 20 = 0.04.
Therefore, the slope of the line segment representing the flight is 0.04.

helppppppppppppppppppp
Step-by-step explanation:
sqrt(x + 2) - 15 = -3
sqrt(x + 2) = 12 (add 15 to both sides)
x + 2 = 12² = 144 (square both sides)
x = 142.
Answer:
x = 142
Step-by-step explanation:
√x+2 - 15 = -3 (Given)
√x+2 = 12 (Add 15 on both sides)
x + 2 = 144 (Square both sides to get rid of the radical)
x = 142 (Subtract 2 on both sides)
What is 1,864.29 - 375
Answer:
1489.29

Ignore the decimals, and just subtract 375 from 1864. That gives you 1489. Put the decimal values back and you get your answer of 1489.29.
Use the scale drawing and the scale factor to enlarge a square that has a side length of 12 in. Scale factor= 3 in:2m.
Which proportion could you use to solve the side length, x, of the enlarged square?
Given:
The side of square = 12 in.
Scale factor of enlargement = 3 in : 2 m
To find:
The proportion that is use to solve the side length, x, of the enlarged square.
Solution:
Let, the side of length of enlarged square = x m
In case of enlargement the corresponding sides are proportional.
[tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex]
[tex]3x=2\times 12[/tex]
[tex]3x=24[/tex]
Divide both sides by 3.
[tex]x=\dfrac{24}{3}[/tex]
[tex]x=8[/tex]
Therefore, the required proportion is [tex]\dfrac{3}{12}=\dfrac{2}{x}[/tex] and the side length of the square after enlargement is 8 m.
