In a certain automobile manufacturing paint shop, paint defects on the hood occur at a mean rate of 0.8 defect per square meter. A hood on a certain car has an area of 3 square meters. (a) Justify the use of the Poisson model. (b) If a customer inspects a hood at random, what is the probability that there will be no defects? (c) One defect? (d) Fewer than two defects?
Considering the situation described, we have that:
a) The Poisson distribution is used because we only have the mean.
b) There is a 0.0907 = 9.07% probability that there will be no defects.
c) There is a 0.2177 = 21.77% probability that there will be one defect.
d) There is a 0.3084 = 30.84% probability that there will be fewer than two defects.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.Item a:
The Poisson distribution is used because we only have the mean.
We have 0.8 defects per m² and 3 m², hence the mean is given by:
[tex]\mu = 3 \times 0.8 = 2.4[/tex]
Item b:
The probability is P(X = 0), hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-2.4}(2.4)^{0}}{(0)!} = 0.0907[/tex]
There is a 0.0907 = 9.07% probability that there will be no defects.
Item c:
The probability is P(X = 1), hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 1) = \frac{e^{-2.4}(2.4)^{1}}{(1)!} = 0.2177[/tex]
There is a 0.2177 = 21.77% probability that there will be one defect.
Item d:
The probability is P(X < 2), hence:
P(X < 2) = P(X = 0) + P(X = 1) = 0.0907 + 0.2177 = 0.3084.
There is a 0.3084 = 30.84% probability that there will be fewer than two defects.

Katie needs 60 mL of a 10% acid solution for a science experiment. She has available a 8% solution and a 20% solution.
How many milliliters of the 8% solution and how many milliliters of the 20% solution should she mix to make the 10%
solution?
Answer:
The solution would be to solve two equations simultaneously.
Step-by-step explanation:
The solution would be to solve two equations simultaneously.
So let X = ml of 8 % SOLUTION and Y = ml of 20 % SOLUTION
We know that X + Y must = 60 ml.
So first equation is X + Y = 60
The second equation is the statement of the problem
0.2 X + 0.08 Y = 0.1 x 60 = 6
Second equation reduces to
0.2 X + 0.08 Y = 6
Solve the two equations for X and Y and you have your answer.
Factor x ^ 3 - 4x ^ 2 + 7x - 28 by grouping. What is the resulting expression?
O (x ^ 2 + 7)(x - 4)
O (x ^ 2 - 7)(x + 4)
O (x ^ 2 + 4)(x - 7)
O (x ^ 2 - 4)(x + 7)
Answer:
A
Step-by-step explanation:
x³ - 4x² + 7x - 28
= x²(x - 4) + 7(x - 4)
= (x - 4)(x² + 7)
= A
As per the given data, the resulting expression after factoring by grouping is [tex](x^2 + 7)(x - 4)[/tex], which is option A.
What is Factor?Factoring is the process of finding the factors of an algebraic expression, which involves writing the expression as a product of simpler expressions.
There are different methods for factoring, depending on the type of expression. Some common methods include: Factoring by grouping, Factoring quadratics, and Factoring higher degree polynomials.
We can factor [tex]x^3 - 4x^2 + 7x - 28[/tex] by grouping the first two terms and the last two terms as follows:
[tex]x^3 - 4x^2 + 7x - 28= (x^3 - 4x^2) + (7x - 28)\\= x^2(x - 4) + 7(x - 4)\\= (x^2 + 7)(x - 4)[/tex]
Therefore, the resulting expression after factoring by grouping is (x^2 + 7)(x - 4), which is option A.

What is the measurement of the third angle of a triangle,if the measurement of the two angles are 50° and 58°
A.32°
B.42°
C.72°
D.82°
Paki sagot po
Given :
The measurement of the two angles of a triangle are 50° and 58°.⠀
To Find :
The measurement of the third angle of the triangle.⠀
Answer :
72° .⠀
Explanation :
We know that,
Sum of all angles of a triangle = 180°⠀
Therefore,
[tex]{ \longrightarrow \sf \qquad \angle1 + \angle2 + \angle3= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 50 {}^{ \circ} + 58{}^{ \circ}+\angle3= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 108{}^{ \circ}+\angle3= 180 {}^{ \circ} }[/tex]
⠀
Subracting 108° from both sides :
[tex]{ \longrightarrow \sf \qquad 108{}^{ \circ} - 108 {}^{ \circ} +\angle3= 180 {}^{ \circ} - 108 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \pmb{\bf \qquad \angle3= 72 {}^{ \circ} }}[/tex]
⠀
Therefore,
The measurement of the third angle of the triangle is 72° .Ben says the angle is an acute angle. Jeff says the angle is less than a straight angle. Explain whether their statements are correct.
Answer:
sometimes, if their average angle is over 45 degrees
never are 2 obtuse angles summing to 180 degrees
always. two 90 degree angles always sum to 180 which is a straight line

Evan graphed a cubic function, f(x) = ax3 + bx2 + cx + d, and determined the roots of f(x) to be +1 and 2. What is the value of b, if a = 1
The value of [tex]b[/tex] in the cubic polynomial is -4.
How to determine the coefficients of a cubic polynomialAfter a quick analysis, we find that given cubic function is equivalent to the following equivalence:
[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = (x-1)^{2}\cdot (x-2)[/tex]
[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = (x^{2}-2\cdot x + 1)\cdot (x-2)[/tex]
[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-2\cdot x^{2}+x-2\cdot x^{2}+4\cdot x-2[/tex]
[tex]x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-4\cdot x^{2}+5\cdot x -2[/tex]
After a quick observation, we conclude that the value of [tex]b[/tex] in the cubic polynomial is -4. [tex]\blacksquare[/tex]

Find the diameter of a circle whose circumference is 77
We are given that the circumference of a circle is 77 units and we need to find it's diameter . But let's recall that for any Circle with radius r , the circumference is given by 2πr . And diameter is double of radius i.e d = 2r , so we can write the circumference as 2r(π) i.e dπ . So , now here
[tex]{:\implies \quad \sf d\pi =77}[/tex]
[tex]{:\implies \quad \sf d\times \dfrac{22}{7}=77}[/tex]
[tex]{:\implies \quad \sf d=\dfrac{77\times 7}{22}}[/tex]

PLS ANSWER QUICKLY WILL MARK BRAINLIEST
Answer:
2 π R^2 = 72 π area of the two circles
R^2 = 36
R = 6
Area of rectangle = 2 R * 4 R = 8 R^2
Area = 8 * 36 = 288
Note area of one circle = π R^2 = π 36 = 113

Suppose that f(x)=x2 and g(x) =4/5x2. Which statement best compares the graph of f(x)?
Answer:
See below.
Step-by-step explanation:
Are f(x)=x2 and g(x) =4/5x2 correctly written?
This answer assumes they are supposed to be:
f(x)=x^2 and g(x) = (4/5)x^2
If these revisions are correct, g(x) would produce values that are (4/5) of f(x).
