Answer:

yes

Step-by-step explanation:

Solving the 2 equations to find the point of intersection

y = 3x - 1 → (1)

y = - x + 3 → (2)

Since both equations express y in terms of x, equate the right sides

3x - 1 = - x + 3 ( add x to both sides )

4x - 1 = 3 ( add 1 to both sides )

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting x = 1 in (2)

y = - 1 + 3 = 2

Thus (1, 2) is the point of intersection

A rectangle has a length of twenty one cm and a diagonal of twenty nine cm. How wide is the rectangle?

GuDViN [60]

The width of the rectangle become 20 cm.

According to the statement

we have to find the width of the rectangle.

So, For this purpose, we know that the

Rectangle is a parallelogram all of whose angles are right angles.

According to the information:

A rectangle has a length of 21 cm and a diagonal of 29 cm.

Here we use the this formula

d² = l² + w²

So, Substitute the values

29² = 21² + w²

841 = 441 + w²

Now, solve it then

w² = 400

Solve the square root then value becomes

w = 20 cm.

The width of the rectangle become 20 cm.

So, The width of the rectangle become 20 cm.

A disease has a constant force of mortality, µ. Historically 10% of all people with the disease die within 20 years. A more viru

kolbaska11 [484]

Answer:

Step-by-step explanation:

For the disease having force of mortality µ.

we apply exponential distribution law

probability of dying within 20 years

p( x <20) = $1-e^{-\mu}$ = .1

$e^{-\mu}$ = .9

For the disease having force of mortality 2µ.

we apply exponential distribution law

probability of dying within 20 years

p( x <20) = 1 - $e^{-2\mu}$

= 1 - ( .9)²

= 1 - .81

= .19

or 19%
