An attendant at a car wash is paid according to the number of cars that pass through. Suppose that following payments are made with the following probabilities: Payment Probability $7 0.18 $9 0.08 $11 0.09 $13 0.16 $15 0.08 $17 0.41 Find the standard deviation of the attendant's earnings.

Answers

Answer:

E(X) = 7*0.18 +9*0.08 +11*0.09 +15*0.08 +17*0.41 =13.22

And 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) = 7^2*0.18 +9^2*0.08 +11^2*0.09 +15^2*0.08 +17^2*0.41 =189.72

And we can find the variance like this:

Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516

And the deviation would be:

Sd(X)= √(14.9516)= 3.867

Step-by-step explanation:

For this case we have the following dataset given:

Payment     $7     $9     $11    $13    $15  $17

Probability 0.18  0.08  0.09  0.16  0.08   0.41

For this case we can calculate the mean with this formula:

E(X) = \sum_(i=1)^n X_i P(X_i)

And replacing we got:

E(X) = 7*0.18 +9*0.08 +11*0.09 +15*0.08 +17*0.41 =13.22

And 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) = 7^2*0.18 +9^2*0.08 +11^2*0.09 +15^2*0.08 +17^2*0.41 =189.72

And we can find the variance like this:

Var(X) = E(X^2) -[E(X)]^2= 189.72- (13.22)^2 =14.9516

And the deviation would be:

Sd(X)= √(14.9516)= 3.867

Select all the properties of a non -square rectangle ? 3 Same -Side angles supplemental

Answers

Answer

Check Explanation

Explanation

Supplementary angles are angles that sum up to give 180 degrees.

And for all rectangles, whether a square one or non-square one, all of the angles of the rectangle are each 90 degrees.

So, it is clear that any two same side angles will be 90° + 90° = 180°

Meaning that same side angles of a non-square rectangle are supplemental.

Hope this Helps!!!

Can yah help me with those two question please

Answers

Solution1:-

Statement : corresponding angles in similar triangles must be congruent .

Answer : True

Solution2:-

Statement : The hypotenuse of a right angle triangle has to be opposite of 90 degree .

Answer : True

Reason : We know that the side opposite to largest angle in a triangle is largest . Since in a right angle triangle 90 degree is the largest angle and hypotenuse is the longest side therefore they must be opposite to each other .

Steven wants to make some extra money using a CD account. He wants $22,000 in his account after 5 yearscompounded continuously. How much principal will he have to start with, at an interest rate of 6.625%?

Answers

Answer: You got to multiply 22,000 times 5 and that will equal 110,000

Step-by-step explanation:

Final answer:

To have a final balance of $22,000 in a CD account after 5 years with continuous compounding at an interest rate of 6.625%, Steven needs to initially deposit approximately $15,895.68.

Explanation:

To calculate how much principal Steven should start with in his CD account, we need to use the formula for continuous compounding, which is A = Pe^(rt), where:

  • A is the amount of money accumulated after n years, including interest.
  • P is the principal amount (the initial amount of money).
  • e is the base of the natural logarithm, approximately equal to 2.71828.
  • r is the annual interest rate (decimal).
  • t is the time the money is invested for in years.

In Steven's case, he wants A = $22,000 after t = 5 years, at an interest rate r of 6.625% or 0.06625 in decimal format. Substituting these values into our formula and solving for P, we get:

P = A / e^(rt)

P = 22000 / e^(0.06625 * 5)

After calculating this expression, we find that Steven needs to deposit approximately $15,895.68 into his CD account to have $22,000 after 5 years with continuousinterest compounding at 6.625%.
