Use the substitution method to solve the system of linear equations.
y = x - 4
4x + y = 26
Answer:
y = 2 and x = 6
Step-by-step explanation:
Let y = x - 4 be equation a
Let 4x + y = 26 be equation b
Substitute a into b:
4x + (x-4) = 26
5x - 4 = 26
5x = 30
x = 6
Substitute the value of x into a:
y = x - 4
y = 6 - 4
y = 2
CHECK:
4x + y = 26
4*6 + 2 = 26
24 + 2 = 26
26 = 26
LHS = RHS
Therefore, y = 2 and x = 6
if 5 books are picked at random from a shelf containing 8 novels, 3 books of poems, and a dictionary, what is the probability that
The probability that the dictionary is selected is 0.417, 3 novels and 2 books of poems are selected is 0.707. The probability that 4 novels are selected is 0.354.
The probability that the dictionary is selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select the dictionary and 4 other books.
The total number of ways to select 5 books from the shelf is:
C(12,5) = 12! / (5! * 7!) = 792
The number of ways to select the dictionary and 4 other books is:
C(1,1) * C(11,4) = 11! / (4! * 7!) = 330
Therefore, the probability that the dictionary is selected is:
P(dictionary) = 330/792 = 0.417
The probability that 3 novels and 2 books of poems are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 3 novels and 2 books of poems.
The total number of ways to select 5 books from the shelf is:
C(12,5) = 12! / (5! * 7!) = 792
The number of ways to select 3 novels and 2 books of poems is:
C(8,3) * C(3,2) = (8! / (3! * 5!)) * (3! / (2! * 1!)) = 560
Therefore, the probability that 3 novels and 2 books of poems are selected is:
P(3 novels, 2 books of poems) = 560/792 = 0.707
The probability that 4 novels are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 4 novels and 1 other book.
The total number of ways to select 5 books from the shelf is:
C(12,5) = 12! / (5! * 7!) = 792
The number of ways to select 4 novels and 1 other book is:
C(8,4) * C(4,1) = (8! / (4! * 4!)) * (4! / (1! * 3!)) = 280
Therefore, the probability that 4 novels are selected is:
P(4 novels) = 280/792 = 0.354

a steel plate contains 20 bolts. assume that five bolts are not torqued to the proper limit. four bolts are selected at random, without replacement, to be checked for torque. (a) what is the probability that all four of the selected bolts are torqued to the proper limit?
The probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.
To calculate the probability that all four of the selected bolts are torqued to the proper limit, we need to find the number of combinations of 4 bolts out of 20 that have been torqued to the proper limit.
Let's call the number of proper bolts n = 20 - 5 = 15.
The number of combinations of 4 proper bolts out of 15 is given by the binomial coefficient nCk, where n is the number of bolts and k is the number of bolts selected.
nCk = n! / (k! (n - k)!).
So, the number of combinations of 4 proper bolts out of 15 is:
15C4 = 15! / (4! (15 - 4)!) = 15! / (4! 11!) = 1365.
Therefore, the probability of selecting all 4 proper bolts out of 20 is:
P = number of combinations of 4 proper bolts / number of combinations of 4 bolts = 1365 / 20C4 = 1365 / 4845 = 0.28
So, the probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.

Find the length of the segments and the measure of the angles: CF, FE, ∠D, and ∠
Length of the segments are 11 units and 10 units and measures of the angles are 54° and 126°.
What is Parallelogram?Parallelogram is a type of polygon with four sides, four angles and four vertices. It is a type of Quadrilateral.
Opposite sides are parallel, and the opposite sides and opposite angles are equal.
Since, CDEF is a parallelogram, opposite angles are equal.
(9y)° = (7y + 28)°
9y - 7y = 28
2y = 28
y = 14
∠C = ∠E = 9y = 126°
Sum of the angles of a quadrilateral is 360°.
∠D = ∠F = (360° - (126°×2)) / 2 = 54°
Opposite sides are also equal for a parallelogram.
2x = x + 5
2x - x = 5
x = 5
CF = DE = 2x = 10 units
CD = FE = 3x - 4 = 11 units

Given that P=1.80 and Q=2.91, find ghe relative error in the computation of 1/P-1/Q
Answer:
±1.007%
Step-by-step explanation:
You want the relative error in the computed value of 1/P -1/Q when P=1.80 and Q=2.91.
Maximum and minimumEach of P and Q is specified to the hundredths place, so the errors in each of P and Q will be half of a hundredth, or 0.005. The maximum value of P or Q will be 0.005 more than the given value, and the minimum will be 0.005 less.
The maximum and minimum of the computation will be had when P and Q are at their opposite extremes: one is a maximum when the other is a minimum.
Max difference = 1/1.795 -1/2.915 ≈ 0.21404
Min difference = 1/1.805 -1/2.905 ≈ 0.20978
Relative errorThe relative error in the computed value can be found a couple of ways. One is to compare the maximum and minimum computed values with the nominal computed value.
Here, we choose to compare half the difference in the computed values to the average of the computed values. That way, we can describe the error as symmetrical about that average;
((0.21404 -0.20978)/2) / ((0.21404 +0.20978)/2) = relative error
= (0.21404 -0.20978) / (0.21404 +0.20978) ≈ 0.01007
The relative error is about ±1.007%.
__
Additional comment
Another way to compute the error is by looking at the derivatives. The relative error found that way is ...
RE = -∆P(Q/P(Q -P)) +∆Q(P/Q(Q -P))
where ∆P and ∆Q are ±0.005.
The maximum relative error found this way is about ±1.00686% compared to the ±1.00685% computed above.
If you compare the possible error to the nominal value, it is not symmetrical: -1.00532% to 1.00841%.
Looking at the above expression for RE, you see that the multiplier of the relative error in P is Q/(Q-P), while the multiplier of the relative error in Q is P/(Q-P). That is, errors in P have a much larger effect than errors in Q.

what is the period of the function f(x) shown in the graph?
Answer:
8π
Step-by-step explanation:
The period of a function f(x) is the x-distance between two repeating points of the function
Looking at the function graph given we see that the function reaches a peak value(called amplitude) at x = -6π and then again reaches this value at x = 2π
So the x-distance is 2π - (-6π) = 2π + 6π = 8π
From 2π, the function reaches its maximum value again at 10π giving the period once again as 10π - 2π = 8π
Find the lengths of the diagonals of rectangle WXYZ.
WY = 24x-8
XZ = -18x+13
The length of each diagonal is ___ units.
In rectangle WXYZ, the length of each diagonal are 40.97 units and 39.98 units.
To find the lengths of the diagonals of rectangle WXYZ, we can use the Pythagorean theorem.
The diagonal WX is the hypotenuse of right triangle WXY, so we have:
WX^2 = WY^2 + XY^2
Similarly, the diagonal YZ is the hypotenuse of right triangle XYZ, so we have:
YZ^2 = XY^2 + XZ^2
Substituting the given values for WY and XZ, and x = 2, we get:
WY = 24(2) - 8 = 40
XZ = -18(2) + 13 = -23
Plugging these values into the equations above and simplifying, we get:
WX^2 = 40^2 + XY^2
YZ^2 = XY^2 + (-23)^2
Since XY is a common side of both triangles, we can solve for it by setting the two expressions for XY^2 equal to each other:
40^2 + XY^2 = XY^2 + (-23)^2
Simplifying, we get:
40^2 + 23^2 = 2XY^2
XY^2 = (40^2 + 23^2) / 2 = 1039
Substituting this value for XY^2 in the equations for WX^2 and YZ^2, we get:
WX^2 = 40^2 + 1039 = 1679
YZ^2 = 1039 + (-23)^2 = 1598
Taking the square roots, we get:
WX = sqrt(1679) ≈ 40.97
YZ = sqrt(1598) ≈ 39.98
Therefore, the length of each diagonal of Rectangle are approximately 40.97 units and 39.98 units.
