Step-by-step explanation:

The multiplier that would be used to calculate the depreciation of the car is 0.83^y.

Depreciation is when the value of an asset declines due to wear and tear.

The equation that can be used to represent depreciation is:

Value of the asset x (1 - rate of depreciation)^years

$31,000 x 0.83^y.

Answer:

x = 24

PS = 45

Step-by-step explanation:

Perimeter of P Q R S is :

( 4x + 1 ) + ( 2x - 3 ) + ( 2x - 3 ) + 4 + ( 4x + 1 )

4x + 1 +  2x - 3  +  2x - 3 + 4 +  4x + 1

And in the question , given that the perimeter of this figure is 288.

Now let us find the value of x.

4x + 1 +  2x - 3  +  2x - 3 + 4 +  4x + 1  = 288

4x + 2x + 2x + 4x + 1 - 3 - 3 + 4  + 1 = 288

12x + 0 = 288

12x = 288

Divide both sides by 12

x =  24

And now let us find the value of PS

PS = 2x - 3

PS = 2× 24 - 3

PS = 48 - 3

PS = 45

Answer:

2 mm

Step-by-step explanation:

Let x be the sides of the original square,

then the area of the original square is x^2

The sides of the new square is x + 6

The area is (x + 6)^2

Then (x + 6)^2 = 16*x^2

Take square root on both sides and get

x + 6 = 4x,

3x = 6

so x = 2 mm

Answer:

(exact form)   z= -7/5

or

(decimal form)   z= -1.4

or

(mixed number form)   z= -12/5

Step-by-step explanation:

Answer:

The value of z is -7/5

Step-by-step explanation:

1/3 (z + 1/5) = -2/5

z/3 + 1/5 × 3 = -2/5

z/3 + 1/15 = -2/5

15z + 3/45 = -2/5

15z + 3 = -2(45) ÷ 5

15z + 3 = -2(9)

15z + 3 = -18

15z = -18 – 3

15z = -21

z = -21/15

z = -7/5

Thus, The value of z is -7/5

Answer:

Step 1

Step-by-step explanation:

they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.

Answer:

B. Incorrect with error in STEP 1

Step-by-step explanation:

3x - x + 4 = 4(2x - 1)

Step 1: Simplify

2x + 4 = 8x - 4

Step 2: Subtract 8x from both sides.

2x+4−8x=8x−4−8x

−6x+4=−4

Step 3: Subtract 4 from both sides.

−6x+4−4=−4−4

−6x=−8

Step 4: Divide both sides by -6.

-6x/-6 = -8/-6

x = 4/3

so, the other answer is wrong because she did not multiply the numbers in the parenthesis correctly

Using the Poisson distribution, it is found that there is a 0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

Flaws in a certain type of drapery material appear on the average of one in 150 square feet, hence, considering 300 square feet, the mean is of:

[tex]\mu = \frac{300}{150} \times 1 = 2[/tex]

The probability of at least one flaw appearing in 300 square feet is given by:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-2}2^{0}}{(0)!} = 0.1353[/tex]

Then:

[tex]P(X \geq 1) = 1 - 0.1353 = 0.8647[/tex]

0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.

Answer:

y=1/5x-4

Step-by-step explanation:

Hi there!

We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)

There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We are already given the slope (1/5), so we can plug it in as m in the equation.

y=1/5x+b

Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept

In this case, b would equal -4

So substitute -4 as b into the equation:

y=1/5x-4

This is the equation of the line.
