3. According to The Motorist, a publication of the American Automobile Association, 90% of all calls for emergency
Service on a cold winter day in Tottenville are for cars that won't start because of a dead battery, 10% of the calls a
cars that won't start because they have no gas, and 4% of the calls are for cars that won't start because of a dead
battery and no gas. If a typical call is randomly selected, what is the probability that it is for a car that won't start
because of a dead battery or because of no gas?

Answers

Answer 1

Answer:

The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas is 0.96

Step-by-step explanation:

The percentage of calls for emergency due to dead battery = 90%

The percentage of calls for emergency due to no gas = 10%

The percentage of calls for emergency due to dead battery and no gas  = 4%

Therefore;

The probability that a call for a car that won't start because of dead battery, P(B) = [tex]\left | B \right |[/tex] = 0.9

The probability that a call for a car that won't start because of no gas, P(N) = [tex]\left | N \right |[/tex] = 0.1

The probability that a call for a car that won't start because of dead battery and no gas, P(B∩N) = [tex]\left | B \cap N \right |[/tex] = 0.04

Therefore, the probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas is given as follows;

[tex]\left | B \cup N \right | = \left | B \right | + \left | N \right | - \left | B\cap N \right |[/tex]

Where;

Therefore, we have;

[tex]\left | B \cup N \right |[/tex] = The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas

Substituting gives;

[tex]\left | B \cup N \right |[/tex] = 0.9 + 0.1 - 0.04 = 0.96

∴ The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas = 0.96.

2 X + 3 Y=_ 4
_ 5 x + 4 Y + 13 =0 ​

Answers

X = -10

Y = 8

2 X + 3 Y = 4 ---- (i)

5 X + 4 Y + 13 = 0 ---- (ii)

rearranging eqn (ii), we have

5X + 4Y = -13 ----- (ii)

multiply eqn (i) by 5 and eqn (ii) by 2

10X + 15Y = 20 ---- (iii)

10X + 8Y = -26 ---- (iv)

subtracting eqn (iv) from (iii), we have

10X - 10X + 15Y - 8Y = 20 - (-26)

0 + 7Y = 20 + 26

7Y = 56

Y = 56/7

Y = 8

Substituting Y into eqn (i), we have

2X + 3Y = 4

2X + 3(8) = 4

2X + 24 = 4

2X = 4 - 24

2X = -20

X = -20/2

X = -10

The sum of two numbers is 64 and the difference is 8. What are the numbers?

Answers

Answer:

The answer is 36 and 28

Step-by-step explanation:

Trust me its correct

pls mark me as brainliest

The addition is one of the four fundamental mathematical operations. The two of the given numbers are 36 and 28.

What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Let the sum of two numbers be represented by a and b.

Given that the sum of the two numbers is 64. Therefore, we can write,

a + b = 64

Also, it is given that the difference between the two numbers is 8, therefore, we can write,

a - b = 8

Adding the two of the equation formed together, then,

a + b + a - b = 64 + 8

2a = 72

a = 72/2

a = 36

Substitute the value of a in any one of the two equations,

a + b = 64

36 + b= 64

b = 64 - 36

b = 28

Hence, the two of the given numbers are 36 and 28.

Parallel to 3x + y=5
and passing through (2, 3)

Answers

Answer:

Step-by-step explanation:

We know that parallel line must have the same slope

First we change the given equation to slope intercept form      y =mx +b

From 3x+y=5 ( we need to find the new y intercept using the given x and y values of (2,3)

find for y by subtracting 3x from both sides of the equation

3x +y = 5 -3x

-3x

we get :  y = -3x +5

Use the x and y values given (2,3) and substitute in the equation above

to find find for b (remember we need a new y intercept..b)

y = -3x + b

3 = -3(2) + b

3 = -6 + b

b = 6 = 3

b = 9

The new equation that's parallel to the given equation would be

y = -3x + 9

Function is a type of relation, or rule, that maps one input to specific single output.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given a function as f(x) = - 4(x + 3)

f(4) is another notation for x = 4
