Kevin and Randy Muise have a jar containing 68 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $8.00. How many of each
type of coin do they have?
The jar contains
quarters

Answers

Answer 1

9514 1404 393

Answer:

23 quarters45 nickels

Step-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

Answers

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

Answers

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)

(a) Find the probability that the number that prefer to purchase electronics online is exactly five.

P(5)=

Answers

Using the binomial probability relation, the probability of the following events are :

P(x = 5) = 0.2076P(x > 5) = 0.6785P(x ≤ 5) = 0.3215

Using the relation :

P(x = x) = nCx * p^x * q^(n-x)

Probability of success, p = 0.75q = 1 - p = 1 - 0.75 = 0.25Number of trials, n = 8

Probability of exactly 5 :

P(x = 5) = 8C5 × 0.75^5 × 0.25^3

P(x = 5) = 0.2076

2.) Probability of selecting more than 5 :

P(x > 5) = p(6) + p(7) + p(8)

Using a binomial probability calculator :

P(x > 5) = 0.6785

3.)

Probability at most 5 :

P(x ≤ 5) = p(0) + p(1) + p(2) + p(3) + p(4) + p(5)

Using a binomial probability calculator :

P(x ≤ 5) = 0.3215

Therefore, the probability of selecting at most 5 is 0.3215

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.

Answers

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.
