3. b = 3

5. x = 12

7. r = 5

9. v = -225

Step-by-step explanation:

3. b - 15 = -12  

To get b by itself we have to add 15 to both sides.

b = 15-12

b = 3

5. x-5 = 7

To get x by itself we have to add 5 to both sides.

x = 5+7

x = 12

7. r + 6 = 11

To get r by itself we have to subtract 6 to both sides.

r = 11-6

r = 5

9. [tex]\frac{v}{15}[/tex] = -15

To get v by itself we have to multiply [tex]\frac{v}{15}[/tex] by its opposite reciprocal which is [tex]\frac{15}{1}[/tex]

v = -15(15)

v = -225

The probability for event A is 0. 3, the probability for event B is 0. 6, and the probability of events A or B is 0. 8. Why are the events not mutually exclusive?.

Answers

P(A and B) = P(A) + P(B) - P(A or B)

P(A and B) = 0.3 + 0.6 - 0.8

P(A and B) = 0.1

Because this result is nonzero, the two events A and B are not mutually exclusive. It is possible for the two events to happen at the same time.

Mutually exclusive events always have P(A and B) = 0, which means A and B cannot happen simultaneously.

The probability of A or B equals the probability of A plus the probability of B. so, the event is not mutually exclusive because of the P(A and B) = 0.1, not 0.

Given that,

The probability for event A is 0.3, the probability for event B is 0.6,

and the probability of events A or B is 0.8.

We have to find,

Why are the events not mutually exclusive?

According to the question,

The probability for event A is 0.3, the probability for event B is 0.6,

and the probability of events A or B is 0.8.

P(A) = 0.3

P(B) = 0.8

and P(A∪B) = 0.8

When two events are said to be mutually exclusive when both the events cannot take place simultaneously.

Mutually exclusive events always undergo different outcomes.

These events are also known as disjoint events.

Mutually exclusive events prevent the second event to take place when the first event appears.

The probability of mutually exclusive events follows;

The probability of A and B together equals 0,

P(A and B) = 0

The probability of A or B equals the probability of A plus the probability of B,

P(A or B) = P(A) + P(B)

Therefore,

P(A or B) = P(A) + P(B) = 0.3 + 0.6 = 0.9

Here, 0.9 ≠ 0.8

Thus, the events are not mutually exclusive.

Hence, The event is not mutually exclusive because the P(A and B) = 0.1, not 0.

Navya picked two different numbersfrom set of number cards. 300 is a multiple of both the numbers, Which of these CANNOT be a number she picked?

A. 45
B. 50
C. 60
D. 75

PLS ANSWER ASAP!!! ILL MAKE U BRAINLIEST♡​

Answers

Answer: Choice A)  45

=================================================

Explanation:

Since 300 is a multiple of some number, this means that mystery number is a factor of 300.

So for instance, she could have picked 60 since 60*5 = 300. Or she could have picked 50 because 50*6 = 300.

To find out if you have a factor or not, divide the 300 over each answer choice. If you get a whole number, then it is a factor.

A) 300/45 = 6.67 approximatelyB) 300/50 = 6C) 300/60 = 5D) 300/75 = 4

Choices B through D lead to whole number results, which shows that the numbers 50, 60 and 75 are factors of 300. Flipping things around, this means that 300 is a multiple of 50, 60, and 75.

Only 45 is the one that isn't a factor of 300, which means that 300 is not a multiple of 45.

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

Another way to see this is to list out the multiples of 45

45, 90, 135, 180, 225, 270, 315, 360, ...

and we don't land on 300. The closest we get is 315.

In contrast, let's list out the multiples of 50

50, 100, 150, 200, 250, 300, 350, 400, ...

The value 300 is in the list, allowing us to cross off choice B. Choices C and D are similar.

Answers

Answer: 147 votes

Beacause they need to find out what to do with the beach house

The greatest value in the range for this situation is $2,675.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Let the number of days the beach house is rented be represented by the variable "d".

If d is less than or equal to 7, then the total cost can be calculated as:

Total Cost = 375d + 100

If d is greater than 7, then the maximum cost would be reached by renting the house for 7 days and adding the $100 cleaning fee.

In this case, the total cost can be calculated as:

Total Cost = 375(7) + 100 = 2,675

Therefore,

The greatest value in the range for this situation is $2,675.

in.
C
84−−√
in.
D
104−−−√
in.

Answers

Answer: Choice A.   sqrt(116)

==========================================================

Explanation:

If we were to view a vertical cross section of the cone, then we get a triangle. This triangle splits along the vertical height line to form two congruent right triangles.

The horizontal piece of each triangle is the radius r = 4.

The vertical piece is the height h = 10.

Apply the pythagorean theorem to find the slant height, which is the hypotenuse of the right triangle.

a^2 + b^2 = c^2

r^2 + h^2 = x^2

4^2 + 10^2 = x^2

16 + 100 = x^2

116 = x^2

x^2 = 116

x = sqrt(116)

Step-by-step explanation:

On a die, there is 6 possibilities 2, 3, and 5, are 3 of them.

3/6 is equivalent to 50% and 1/2.

So the odds would be 3/6 for and against. If there are only 6 sides to a die, (1,2,3,4,5,6) and you want to get one of 3 out of the 6, then you have a 50% chance of getting what you want.

Step-by-step explanation:

let the son's age be x then the father's age is x + 20

In 5 years

son = x + 5 and father = x + 20 + 5 = x + 25

Then

x + 25 = 3(x + 5) ← father is three times as old as son

x + 25 = 3x + 15 ( subtract x from both sides )

25 = 2x + 15 ( subtract 15 from both sides )

10 = 2x ( divide both sides by 2 )

5 = x and x + 20 = 5 + 20 = 25

si=on is 5 and father is 25

Answer:

The son is 5 and the father is 25.

Step-by-step explanation:

We can do this using  Algebra.

Let the son be x years old.

Then the father's age is x + 20 years.

After 5 years the father's age is x + 25 and the son is x + 5 years.

So we can write the equation:

x + 25 = 3(x + 5)

x + 25 = 3x + 15

25 - 15 = 3x - x

10 = 2x

x = 5.

So the father's present age is 20 + 5 = 25 and the son is 5 years old.
