Answer:

$x = 52$

$y = 5$

Step-by-step explanation:

Given

The attached triangle

Required

Find x and y

From the triangle; the angle sign in x and 52 means;

$x = 52$

3y and 15 are congruent sides

So:

$3y = 15$

$y = 5$

You bought a car for $50,000. Each year it depreciates in value by 7.5%.

sweet-ann [11.9K]

Answer:

y= 50,000(1-.075)^x

Step-by-step explanation:

The first year of depreciation is calculated by:

50,000 - (0.075)*(50,000) = 46,250

This can also be written as:

(50,000)*(1 - 0.075) [Pull out the 50,000]

The second year will depreciate starting with the $46,250 value at the end of the first year:

46,250 - (0.075)*(46,250) = 42,781

This may be written as:

(46,250)(1 - 0.075) = 42,781

The 46,250 was derived from the first year depreciation calculation, so we can substitute that instead of the 46,250:

((50,000)*(1 - 0.075))(1 - 0.075) = 42,781

This reduces to:

(50,000)*(1 - 0.075)^2 = 42,781. Note that the term (1-0.075) is now raised to the 2nd power. This power represents the 2nd year. Each succeeding year would be raised by one additional power, so that we can write a depreciated value after x years will be:

(50,000)*(1 - 0.075)^x

A bulletin board is 11 feet by 6 feet. The area of the board is what square feet.

Usimov [2.4K]

Answer:

66 feet sq.

Step-by-step explanation:

Eleven times six would be sixty-six.

Break up 11 into its tens and ones

11*6 =60

1*6 =6

Add the two, 60+6 =66

Alex has 64 cubes with dimensions in feet (ft), like the one shown. He uses all the cubes to fill a box shaped like a larger rec

Vilka [71]

Answer:

The volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

Step-by-step explanation:

Length of small cube = $\frac{1}{2} ft$

Volume of each cube = Side^3

Volume of each cube = $(\frac{1}{2})^3$

= $\frac{1}{8} ft^3$

Volume of 64 cubes = $64 \times \frac{1}{8}$

Volume of 64 cubes $= 8 ft^3$

We are given that He uses all the cubes to fill a box shaped like a larger rectangular prism.

So, Volume of 64 cubes = Volume of rectangular prism

So, If there are 64 of these cubes in the larger prism, then the volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

The warranty for a particular system on a new car is 2 years. During which there is no limit to the number of warranty claims pe

const2013 [10]

Answer: by using Poisson distribution

The warranty for a particular system on a new car is 2 years

P(x=2)= 0.143

There is no limit to the number of warranty claims per car

P(X=0) = 0.449

Step-by-step explanation:

<u>step:-1</u>

A random variable X is said to follow a Poisson distribution if it assumes only non-negative values and its probability distribution is given by

P(X=x) = $\frac{e^{-w}w^{x} }{x!}$

here w>0 is called the parameter of the distribution

<u>Step 2</u>:- Given mean value of Poisson distribution = 0.8

The warranty for a particular system a new car is 2 years

P(X=x)=P(X=2)= $\frac{e^{-0.8}{0.8^{2} } }{2!}$

P(x=2)= 0.143

<u>Step 3</u>:-

Given mean value of Poisson distribution = 0.8

There is no limit to the number of warranty claims per car

P(X=x)=P(X=0)= $\frac{e^{-0.8}{0.8^{0} } }{0!}$

P(X=0) = 0.449
