The answer is “40 years old individuals would smoke with the probability do, so with the probability of 24.22%”

<h3>What is probit regression?</h3>

A probit model is a type of regression in statistics where the dependant variable can only take two values.

We have:

Regress smoker on quadratic polynomials of age.

If we use probit regression.

The statement 40 years old individuals would smoke with the probability do, so with the probability of 24.22% is wrong about the statement.

Thus, the answer is “40 years old individuals would smoke with the probability do, so with the probability of 24.22%”

The answer would be B because the sum of the squares of the 2 shorter sides equal the square of the longer side, which is the pythagoream theorem of a^2+b^2=c^2.

What are the two ordered pairs for 5x=-1
jonny [76]
5x = -1

x = -1/5 = -0.2

That means that any ordered pair for the line will be (-0.2, y)

You can put any number in for y.

So two ordered pairs could be:

(-0.2, 1)
and
(-0.2, 2)

The length of a photograph is 1 cm less than twice the width. The area is 91cm^2. find the width and length.
maksim [4K]

Answer:

Width=6.5 cm

Length=12 cm

Step-by-step explanation:

Step 1: Express the lengths and widths

Width=w

Length=l, but 1 cm less than twice the width=(2×w)-1=2 w-1

Step 2: Solve for the length and width

A=L×W

where;

A=area of the photograph

L=length of the photograph

W=width of the photograph

In our case;

A=91 cm²

L=2 w-1

W=w

91=(2 w-1)w

2 w²-w=91

2 w²-w-91=0, is a quadratic equation

solve for w

w={-1±√(-1²-4×2×-91)}/(2×2)

w=(-1±27)/4

w=(27-1)/4=6.5, or (-1-27)/4=-8

Take w=6.5 cm

L=(2×6.5)-1=13-1=12 cm

Width=6.5 cm

Length=12 cm
