Answer:

Step-by-step explanation:

The given equation is

$y=\frac{1}{4}x-1$

Compare it with standard equation

y = mx + c

here m is the slope of the lien and c be the y intersept.

So, by comparison

m = 1/4 , c = -1

Thus, teh slope of line is 1/4 and the y intersept is - 1.

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:

step:-1

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

Step 2:- 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

Step 3:-

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

1) 2 * (10 * 7 + 7 * 1,25 + 10 * 1,25) = 2 * (70 + 8,75 + 12,5) = 2 * 91,25 = 182,5 square inches - a surface area
2) 182,5 * 0,012 = $2,19 - answer.

The line y = kx + 6 is a tangent to the graph of

Wittaler [7]

Answer:

Step-by-step explanation:

For equating the equations, you get

x2 + kx - 3x + 4 = 0 eq1

Setting the derivative of f(x) equal to 3 yields

f'(x) = 3

2x + k = 3 eq2

Now we substitute the value of k from eq2 into eq1.

x2 + x(3 - 2x) - 3x + 4 = 0

Solve for x from this equation. Then plug in the value of x into eq2 to solve for k
