Logarithms:


A law was established, in which it considers that a driver who has more than 0.8 grams of alcohol per liter of blood, is in a state of drunkenness. It is estimated that the risk that a person has of suffering an accident when driving a vehicle under the influence of alcohol is given by the expression [tex]R(x) = 6 * e^{kx}[/tex] , where R(x) is the risk expressed as probability, X is the concentration of alcohol in the blood and K a constant:


A) Calculate the value of the constant K knowing that the concentration of 0.04 g / L of alcohol in the blood (x = 0.04) corresponds to an accident risk of 10% (R = 10)


B) A person who, according to the Law, drives while intoxicated, that is to say 0.8 g / L in blood, what are the risks of suffering an accident?


C) If a driver is under the influence of alcohol, that is 0.3 g / L, what is the risk of having an accident?

Answer 1

Answer:

A) k = 18.75B) R(0.8) = 161419C) R(0.3) = 275

Step-by-step explanation:

Given expression

R(x) = 6*e^(kx)

A) Given

x = 0.04R = 10

Solving for k

10 = 6*e^(0.04k)e^(0.04k) = 10/6ln (e^0.04k) = ln (1.6666)0.04k = 0.51k = 0.51/0.04k = 12.75

B) Given

x = 0.8R= ?

The value of R(0.8) is:

R(0.8) = 6*e^(0.8*12.75) =6*e^(10.2) = 161419  rounded

C) Given

x = 0.3R = ?

The value of R(0.3) is:

R(0.3) =6*e^(0.3*12.75) = 6*e^(3.825) =275 rounded

what is the positive difference between 19&8?​

Answers

Answer:

11

Step-by-step explanation:

The positive difference between 19 and 8 is 11.

What is positive difference?

It is the value which is obtained when the smaller number is subtracted from the bigger number.

For given example,

We need to find the positive difference between 19 and 8.

here, 19 > 8

So, the smaller number = 8

the bigger number = 19

So, the positive difference would be,

19 - 8 = 11

Therefore, the positive difference between 19 and 8 is 11.

I need a step by step explanation please !!!

Answers

Answer:

24% finished, 76% did not

Step-by-step explanation:

12cars/50 total +24%, and then just subtract 100% by the 24 to get 76% for the remaining percent

Answer:

24% finished and 76% did not

Step-by-step explanation:

you have the ratios:

12/50 and 38/50

These have to be turned into percentages so they need to have a denominator of 100

to do this, figure out what you have to multiply the denominator by to get 100

In this case, 50 times 2 is equivalent to 100.

Then, whatever you multiplied the denominator by, you multiply the numerator by

In this case, 12 times 2 is 24 and 38 times 2 is 76

Once you have the end products, take the numerator and add a percentage sign to it

If Q, then R

Therefore, if P then R

We can write it like this

[tex]P \to Q \\\\Q \to R\\\\\therefore P \to R[/tex]

We can think of it like starting at town P, moving to Q, then to R. Or we could go from P directly to R if we aren't worried about the town in the middle (town Q).

455 What is the minimum number of square marbles required to tile a floor of length 6 meter 24
cm. and width 4 meter 16 cm?
A. 6
B. 12
C. 14
D. 8​

Answers

Answer:

6

Step-by-step explanation:

Length of a floor, l = 6 m 24 cm = 624 cm

Breadth of a floor, b = 4 m 16 cm = 416 cm

We need to find the minimum number of square marbles required to tile the floor.

Taking factors of 624 and 416 by prime factorization :

624 = 2 x 2 x 2 x 2 x 3 x 13

416 = 2 x 2 x 2 x 2 x 2 x 13

Their HCF = 208

No of tiles length wise = 624/208 = 3

No of tiles width wise = 416/208 = 2

The minumum no of tiles needed = 3 × 2 = 6

Hence, 6 square tiles are required to tile a floor.
