jeka94

Answer:

Because of the minus sign

2 becomes - 2

The answer is -2

Multiply a and 7

Multiply a and 1

The a just gets copied along.

The answer is a

a

7*a evaluates to 7a

Multiply b and 4

Multiply b and 1

The b just gets copied along.

The answer is b

b

4*b evaluates to 4b

7*a+4*b evaluates to 7a+4b

Multiply -2 by 7a+4b

we multiply -2 by each term in 7a+4b term by term.

This is the distributive property of multiplication.

Multiply -2 and 7a

Multiply 1 and a

The a just gets copied along.

a

-2 × 7a = -14a

Multiply -2 and 4b

Multiply 1 and b

The b just gets copied along.

b

-2 × 4b = -8b

-2*(7*a+4*b) evaluates to -14a-8b

Multiply c and 6

Multiply c and 1

The c just gets copied along.

The answer is c

c

6*c evaluates to 6c

The answer is -14a-8b-6c

-2*(7*a+4*b)-6*c evaluates to -14a-8b-6c

The final answer is

-14a-8b-6c

Pleaseee help, Solve for x and y :3
irina1246 [14]

Answer:

x = \sqrt{6} , y = 2\sqrt{3}

Step-by-step explanation:

using the tangent ratio and the exact value tan45° = 1 , then

tan45° = \frac{opposite}{adjacent} = \frac{x}{\sqrt{6} } = 1 , then

x = \sqrt{6}

----------------------------------

using the cosine ratio in the right triangle and the exact value

cos45° = \frac{1}{\sqrt{2} } , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{\sqrt{6} }{y} = \frac{1}{\sqrt{2} } ( cross- multiply )

y = \sqrt{6} × \sqrt{2} = \sqrt{12} = 2\sqrt{3}

1. Ted found out that the rebate is not given until after he has
nadezda [96]

9514 1404 393

Answer:

  maybe not

Step-by-step explanation:

Consider a couple of scenarios for a $20,000 car purchase and a $2000 rebate, with sales tax at 10%.

1) The rebate is applied directly to the purchase price.

  Taxable amount: $20,000 -2,000 = $18,000.

  Price with tax: $18,000 × 1.10 = $19,800

  Amount financed: $19,800.

__

2) The rebate is given after the sale is complete.

  Taxable amount: $20,000

  Price with tax: $20,000 × 1.10 = $22,000

  Amount financed: $22,000

  Remaining loan balance if $2000 rebate is immediately applied to the loan: $22,000 -$2000 = $20,000

__

If the loan is for 5 years at 3%, the payments and total costs are ...

  Scenario 1: Monthly payment $355.78;

     total cost of loan: 60×355.78 = 21,346.80

  Scenario 2: Monthly payment $395.31;

     total cost of loan: 55×395.31 = $21,742.05  (note there are fewer payments because of the initial payment to principal of $2000)

__

Ted effectively has to finance an additional $200, equal to the sales tax on the rebate. So the delayed rebate costs him an extra $395.25 over the life of the loan.

_____

We have assumed certain tax and payment scenarios. If tax is not an issue, and if the loan terms are such that the rebate can be applied immediately to the loan amount, then <em>there may be no difference in total cost</em>, or the delayed rebate may result in a <em>lower</em> total cost due to the higher monthly payment.

Brian usually brushes his teeth in the morning, but 10% of the time he forgets. What is the probability that he will forget to b
Katena32 [7]

Using it's concept, it is found that there is a 0.001 = 0.1% probability that he will forget to brush his teeth three days in a row.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, for each day, there is a 0.1 probability that he forgers to brush his teeth, and days are independent, hence for 3 consecutive days the probability is given by:

p = (0.1)³ = 0.001.

If y has moment-generating function m(t) = e 6(e t −1) , what is p(|y − µ| ≤ 2σ)?
Lostsunrise [7]
Since \mathrm M_Y(t)=e^{6(e^t-1}, we know that Y follows a Poisson distribution with parameter \lambda=6.

Now assuming \mu,\sigma denote the mean and standard deviation of Y, respectively, then we know right away that \mu=6 and \sigma=\sqrt6.

So,

\mathbb P(|Y-\mu|\le2\sigma)=\mathbb P(6-2\sqrt6\le Y\le6+2\sqrt6)=\dfrac{66366}{175e^6}\approx0.940028
