Answer:

2250 votes

Step-by-step explanation:

Given,

Candidate A  :   Candidate B

        75            :          25

ratio:  3            :            1

If,  candidate B = 750 votes

1 --> 750 votes

3 --> 750 * 3 = 2250 votes

Candidate A receives 2250 votes.

The number of knots in a particular type of wood can be modeled by a Poisson distribution with an average of 1.4 knots in 10 cub
Kamila [148]

Answer:

Probability that a 20- cubic foot block of wood has at most 1 knot P (X<=1) = 0.5918

Step-by-step explanation:

Average rate of knot= 1.4

Wavelength = 1.4

Geometric probability is given by:

P(X= K) = wavelength ^k × e^-wavelegth

P(X=0) = (1.4^0 × e^-1.4)/0!

P(X=0) = 1 × 0.2466 = 0.2466

P(X=1) = 1.4^1 × e^-1.4

P(X=1)= 1.4×0.2466= 0.3452

P(X<=1)= P(X=0) + P(X=1)

P(X<=1) = 0.2466 + 0.3452 = 0.5918

{3x=7y=5<br> {5x-2y=-19
Anton [14]

Answer:

(-3, 2)

Step-by-step explanation:

{3x=7y=5

{5x-2y=-19

solve....

maybe it was  3x + 7y = 5

and  5x - 2y = -19

2*(3x + 7y = 5)

7*(5x - 2y = -19)

-------------

6x + 14y = 10

35x -14y = -133

41x = -123

x = -3

y = ...

5*(-3) - 2y = -19

-15 - 2y = -19

2y = 4

y = 2

An automobile manufacturer is concerned about a possible recall of its best selling four-door sedan. If there was a recall there
goldfiish [28.3K]

Complete question is;

An automobile manufacturer is concerned about a possible recall of its best - selling four-door sedan. If there were a recall, there is a probability of 0.25 of a defect in the brake system, 0.18 of a defect in the transmission, 0.17 of a defect in the fuel system, and 0.40 of a defect in some other area.

(a) What is the probability that the defect is the brakes or the fueling system if the probability of defects in both systems simultaneously is 0.15?

(b) What is the probability that there are no defects in either the brakes or the fueling system?

Answer:

A) 0.27

B) 0.73

Step-by-step explanation:

Let B denote that there is a defect in the break system

Let T demote that there is a defect in transmission

Let F denote that there is a defect in the fuel system.

Let P denote that there is a defect in some other area.

Now, we are given;

P(B) = 0.25

P(T) = 0.18

P(F) = 0.17

P(O) = 0.40

A) We are given that probability of defects in both brakes and the fueling system simultaneously is 0.15.

Thus, it means; P(B ⋂ F) = 0.15

Now, we want to find the probability that the defect is the brakes or the fueling system. This is expressed as;

P(B ⋃ F) = P(B) + P(F) - P(B ⋂ F)

Plugging in the relevant values to give;

P(B ⋃ F) = 0.25 + 0.17 - 0.15

P(B ⋃ F) = 0.27

B) We want to find the probability that there are no defects in either the brakes or the fueling system.

This is expressed as;

P(B' ⋃ F') = 1 - P(B ⋃ F)

Plugging in relevant value;

P(B' ⋃ F') = 1 - 0.27

P(B' ⋃ F') = 0.73
