Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no i
lubasha [3.4K]

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

A = a + (A \cap B)

In which a is the probability that a driver does not have a valid driver's license but has insurance and A \cap B is the probability that a driver does not have any of these things.

By the same logic, we have that:

B = b + (A \cap B)

We start finding these values from the intersection.

4% have neither

This means that (A \cap B) = 0.04

6% of all drivers have no insurance

This means that B = 0.06. So

B = b + (A \cap B)

0.06 = b + 0.04

b = 0.02

12% of all drivers do not have a valid driver’s license

This means that A = 0.12

So

A = a + (A \cap B)

0.12 = a + 0.04

a = 0.08

The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

P = a + b + (A \cap B) = 0.08 + 0.02 + 0.04 = 0.14

So the correct answer is:

e) 0.14

Please help with these 3 questions and show all work!
Bas_tet [7]
Question 1:
"Match" the letters
DE are the last two letters of BCDE
The last two letters of OPQR is QR
DE is congruent to QR

Question 2:
Blank 3: Reflexive property (shared side)
Blank 4: SSS congruence of triangles (We have 3 sets of congruent sides)

Question 3:
I'm guessing those two numbers are 7.
Since both are 7, AB and AE are congruent.
We know that all the other sides are congruent because it is given.
We also know that there is a congruent angle in each triangle.
Thus, the two triangles are congruent by SAS or SSS.
(Note: I couldn't prove this without the two "7"s because there is no such thing as SSA congruence)

Have an awesome day! :)

Find the domain of the function. <br><br> y = <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%2B%201" id="TexFormula1" title
Step2247 [10]

Answer:

[0, infinity)

Step-by-step explanation:

A square root can only use positive numbers, otherwise it becomes imaginary. A function needs to be real to output real values. Therefore, the domain is everything from 0 onwards.
