Answer:
23 quarters45 nickelsStep-by-step explanation:
Let q represent the number of quarters. Then the number of nickels is 68-q, and the number of cents in the jar is ...
25q +5(68 -q) = 800
20q +340 = 800 . . . . simplify
20q = 460 . . . . . . . . subtract 340
q = 23 . . . . . . . . . . . divide by 20; this is the number of quarters
68-q = 45 . . . . . . . find the number of nickels
The jar contains 23 quarters and 45 nickels.

Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1
Answer:
Step-by-step explanation:
Solve the equation for 0 and 1:
x^3 + 6x -5
Replace x with 0:
0^3 + 6(0) -5 = -5
Replace x with 1:
1^3 + 6(1) -5 = 1+6 -5 = 2
Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

Point A is (2, -3) Use each transformation rule to find the coordinates of A’. Final answer in ( )
(x,y) ---->(x +3, y-1) A’=_________________________
(x,y) ----> (x, y-4) A’ = ________________________
By transformation rules, the points A₁(x, y) = (5, - 4) and A₂(x, y) = (2, - 7) are images of point A(x, y) = (2, - 3)
How to obtain the image of a point by a vector
In this problem we must determine two images associated to a given point and that are result of an transformation rule known as a translation. This transformation rule is described below:
A'(x, y) = A(x, y) + T(x, y)
Where:
A(x, y) - Original point.A'(x, y) - Image of the point.T(x, y) - Translation vector.First, write the coordinates of the original point:
A(x, y) = (2, - 3)
Second, find the images of the original point by transformation rule:
A₁(x, y) = (2, - 3) + (3, - 1)
A₁(x, y) = (5, - 4)
A₂(x, y) = (2, - 3) + (0, - 4)
A₂(x, y) = (2, - 7)

combine like terms
8x + 3 = 75
subtract 3 from both sides and divide 8.

what type of mathematical law is this a×m=m×a
Answer:
Commutative Property
Step-by-step explanation:
1. The commutative property is a mathematical law that states that the order in which we multiply numbers does not change the product. Because a × m results in the same answer from multiply m × a, it falls under this property.

Seventy-five percent of consumers prefer to purchase electronics online. You randomly select 8 consumers. Find the probability that the number of consumers who prefer to
purchase electronics online is (a) exactly five, (b) more than five, and (c) at most five.
(a) Find the probability that the number that prefer to purchase electronics online is exactly five.
P(5)=

Using the binomial probability relation, the probability of the following events are :
P(x = 5) = 0.2076P(x > 5) = 0.6785P(x ≤ 5) = 0.3215Using the relation :
P(x = x) = nCx * p^x * q^(n-x)

P(x > 5) = p(6) + p(7) + p(8)
Using a binomial probability calculator :
P(x > 5) = 0.6785

Explain how you can check that the value you found for g is correct. If your check does not work, does that mean that your result is incorrect? Explain. -----------------------------------------------------------------------------------------------------------------------------
Choose the correct explanation below.
A.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
B.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, then the answer must be incorrect.
C.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
D.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, then the answer must be incorrect.
The best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
After solving for a variable in an equation, we can cross check to know if our answer is correct or not.
This can be done by plugging in or substituting the value of the variable g into the equation. In most cases, you will find the variable on both sides.
When you substitute, the value on the left must be equal to the value on the right. If during your check, the value on the left does not equal the value on the right, it simply means the check does not work.
Two things might result to a check not working:
the answer is not correct, oryou made a mistake while checking.Therefore, the best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
