Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 5.3 millimeters (mm) and a standard deviation of 1.1 mm. For a randomly found shard, find the following probabilities. (Round your answers to four decimal places.)
a. the thickness is less than 3.0 mm.
b. the thickness is more than 7.0 mm
c. the thickness is between 3.0 mm and 7.0 mm
Answer:
Follows are the responses to the given question:
Step-by-step explanation:
In point a:
z score for 3:
\(= \frac{(3 - 5.3)}{1.1} \\\\ =-2.09\)
So,
P(Less than 3.0 mm):
\(=P(z < -2.09)\\\\ = 0.0183\)
In point b:
z score for 7:
\(= \frac{(7 - 5.3)}{1.1} \\\\= 1.55\)
So,
P(Less than 3.0 mm):
\(= P(z > 1.55) \\\\= 0.0611\)
In point C:
P(Between 3 and 7):
\(= P(-2.09 < z < 1.55)\\\\\ = 0.9206\)

Answer:
Given that the vertices of quadrilateral PQRS are P(6,3), Q(4,2), R(2,4) and S(4,5) and the quadrilateral is dilated with a scale factor of 2, about the origin.
Now, let's find the new vertices of the dilated image:
Vertex P is dilated by a scale factor of 2, its new coordinates will be (2 × 6, 2 × 3) = (12, 6). Therefore, the new vertex P' is at (12, 6).
Vertex Q is dilated by a scale factor of 2, its new coordinates will be (2 × 4, 2 × 2) = (8, 4). Therefore, the new vertex Q' is at (8, 4).
Vertex R is dilated by a scale factor of 2, its new coordinates will be (2 × 2, 2 × 4) = (4, 8). Therefore, the new vertex R' is at (4, 8).
Vertex S is dilated by a scale factor of 2, its new coordinates will be (2 × 4, 2 × 5) = (8, 10). Therefore, the new vertex S' is at (8, 10).
Therefore, the coordinates of the vertices of the final image are P’(12, 6), Q’(8, 4), R’(4, 8), and S’(8, 10).So, the correct option is D. P’(12, 6), Q’(8, 4), R’(4, 8), and S’(8, 10).

The probability that a randomly selected point within the square falls in the red shaded square is 1/16
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. The certainty of an event to occur is 1 and it is 100% in percentage.
Probability = sample space /total outcome
sample space is the area of the red shaded square and the total outcome is the big square.
Area of red shaded square = 1 × 1 = 1unit²

Christina’s savings account grows at a rate of 2% compounded quarterly. If her initial deposit is $750, write a function A(t)
that models the balance of the savings account after t years.
Answer:
Step-by-step explanation:
A = P * (1 + r/n)^(n*t
The function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit is A = 750(1.0002)^4t. (in dollars)
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
For this case, we're given that:
Initial amount Christina deposits = P = $750
Rate of interest = 2% compounding quarterly
Time = t years
Rate of interest is compounding quarterly.
Each year has 4 quarters.
Quarterly interest rate compounding quarterly = 2%.
t years has 4t quarters = T
Thus, we get the final amount in Christina’s account as
A = P * (1 + r/n)^(n*t)
A = 750(1 + 0.02/100)^4t
A = 750(1.0002)^4t
Thus, the function that gives the amount of money in dollars, J(t), in Christina’s account t years after the initial deposit is A = 750(1.0002)^4t (in dollars)

Find the tangents of the acute angles in the right triangle. Write each answer as a fraction. WILL MAKE BRAINLIEST!!
tan G = ?
tan H = ?
The tangents of the acute angles in the right triangle gives:
tan(G) = 2
tan(H) = 1/2
How to find the tangents of angles?It should be noted that tangent is the ratio of opposite over adjacent. Thus:
tan(angle) = opposite/adjacent
So for reference angle G, we say,
tan(G) = JH/GJ = 2/1 = 2
We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)
So we have this interesting property where
tan(G)*tan(H) = 2*(1/2) = 1
In general,
tan(A)*tan(B) = 1 if and only if A + B = 90 degrees

Los puntos A(13, a) y B (4,b) pertenecen a una parábola de vértice V (h, 1) Además el eje focal es paralelo al eje de las abscisas ,su parámetro es p y A, B están
contenidos en la recta 2x - y - 13 = 0. Hallar a" + bP.
The points on a parabola with the focal axis parallel to the abscissa axis, of parameter p and A, B is -12.
How to calculate parameters?Since A and B are points on the parabola, write two equations using the general form of the parabolic equation:
(x - h)² = 4p(y - 1)
The focal axis is parallel to the x-axis, so the distance from the vertex to the focus is equal to p. Therefore, use the distance formula to write an equation for the distance between the vertex and point A:
√((13 - h)² + (a - 1)²) = p
Similarly, write an equation for the distance between the vertex and point B:
√((4 - h)² + (b - 1)²) = p
A and B lie on the line 2x - y - 13 = 0, so substitute the x and y coordinates of A and B into this equation and solve for a and b:
2(13) - a - 13 = 0
2(4) - b - 13 = 0
Solving these equations gives us a = 3 and b = -5.
Now three equations and three unknowns (a, b, and h):
√((13 - h)² + 4) = p + 1
√((4 - h)² + 36) = p + 1
2h - 3 - 13 = 0
The third equation simplifies to 2h = 16, or h = 8.
Substituting this value of h into the first two equations and squaring both sides:
(13 - 8)² + 4 = (p + 1)²
(4 - 8)² + 36 = (p + 1)²
Simplifying these equations and solving for p gives us p = 3.
Finally, find a" + bP by substituting the values found for a, b, and p:
a" + bP = 3 + (-5)(3) = -12
Therefore, the solution is a" + bP = -12.

c. Find the probability that all four tires have low air pressure.
d. Find the probability that no tires have low air pressure.
e. Compute the mean µX.
f. Compute the standard deviation σX.
Answer:
a) \( P(X=3) = 0.1\)
b) \( P(X\geq 3) =1-P(X<3) = 1-P(X\leq 2) = 1-[P(X=0) +P(X=1)+P(X=2)]\)
And replacing we got:
\( P(X \geq 3) = 1- [0.2+0.3+0.1]= 0.4\)
c) \( P(X=4) = 0.3\)

And replacing we got:

And the variance would be:
\( Var(X0 =E(X^2)- [E(X)]^2 = 6.4 -(2^2)= 2.4\)
And the deviation:

Step-by-step explanation:
We have the following distribution

P(x) 0.2 0.3 0.1 0.1 0.3
Part a
For this case:
\( P(X=3) = 0.1\)
Part b
We want this probability:
\( P(X\geq 3) =1-P(X<3) = 1-P(X\leq 2) = 1-[P(X=0) +P(X=1)+P(X=2)]\)
And replacing we got:
\( P(X \geq 3) = 1- [0.2+0.3+0.1]= 0.4\)
Part c
For this case we want this probability:
\( P(X=4) = 0.3\)
Part d
\( P(X=0) = 0.2\)
Part e
We can find the mean with this formula:
\( E(X)= \sum_{i=1}^n X_i P(X_i)\)
And replacing we got:
\( E(X) =0*0.2 +1*0.3+2*0.1 +3*0.1 +4*0.3= 2\)
Part f
We can find the second moment with this formula
\( E(X^2)= \sum_{i=1}^n X^2_i P(X_i)\)
And replacing we got:
\( E(X^2) =0^2*0.2 +1^2*0.3+2^2*0.1 +3^2*0.1 +4^2*0.3= 6.4\)
And the variance would be:
\( Var(X0 =E(X^2)- [E(X)]^2 = 6.4 -(2^2)= 2.4\)

The solution to the equation 3 / 5x-2 = 2 / 3x-1 is x = 1.
What is the solution to the given equation?Given the equation in the question;
3 / 5x-2 = 2 / 3x-1
To solve for x, cross multiply the equation
3 / 5x-2 = 2 / 3x-1
3( 3x - 1 ) = 2( 5x - 2 )
Apply distributive property
3( 3x - 1 ) = 2( 5x - 2 )
3×3x + 3×-1 = 2×5x + 2×-2
9x - 3 = 10x - 4
Subtract 10x from both sides
9x - 10x - 3 = 10x - 10x - 4
9x - 10x - 3 = - 4
Add 3 to both sides
9x - 10x - 3 + 3 = - 4 + 3
9x - 10x = - 4 + 3
-x = -1
Divide both sides by -1
-x/-1 = -1/-1
