Answer:

No solution

Step-by-step explanation:

y + 12 = y - 20

=> y = y - 20 - 12

=> y - y = -32

=> No solution

Answer:

(i) A = {1}, B = {1, 2}, (ii) A = empty set, B = {1, 2, 3}, (iii) A = {a, b, c}, B = {a, b, c}, (iv)  A = {7, 8, 9, 10}, B = {7, 8, 9, 10, 11, 12}

Step-by-step explanation:

The idea: A U B = the set of all elements (from a Universal set, like the set of all integers) that are in at least one of the sets A or B.  So, for the equation     A U B = B to be true, the set A must be a subset of the set B, because otherwise  A U B would contain at least one element not in B, making the equation A U B = B false (set B would be a proper subset of A U B).  So, if       A = {1, 2, 3, 4} and B = {1, 2, 3}, then A U B = {1, 2, 3, 4}, and A U B = B would be false.  However, if A = {1, 2, 3} and B = {1, 2, 3, 4}, then A U B = B would be true.

Answer:

f(x)=x+12

Step-by-step explanation:

To check if it is right:

plug in the numbers to the equation

f(x)=5+12=17

f(x)=6+12=18

Answer:

2, 5, 9, 10

Step-by-step explanation:

add 2 to the x value to find the f(x) value

The relationship between temperature and the number of chirps based on the information given goes thus :

Let :

1.) Chirps per minute if temperature is 90°F

Put f = 40°F into the equation :

[tex] 90 - 40 = \frac{n}{3}[/tex]

[tex] 50 = \frac{n}{3}[/tex]

[tex] n = 50 \times 3 = 150 chirps [/tex]

2.) Fahrenheit temperature if n = 72

[tex] f - 40 = \frac{72}{3}[/tex]

Cross multiply

[tex] 3(f - 40) = 72[/tex]

[tex] 3f - 120 = 72[/tex]

[tex] 3f = 72 + 120 [/tex]

[tex] 3f = 192[/tex]

[tex] f = \frac{192}{3} = 64 [/tex]

3.)

The equation for the relationship with f = Fahrenheit temperature and x = number of chirps

[tex] f - 40 = \frac{x}{3}[/tex]

Answer:

1/4

Step-by-step explanation:

Find HCD (Highest Common Factor) for both numerator and denominator.

The HCF for 25 and 100 is 25

Now divide the numerator and denominator by 25

A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset of possible experiment results. Depending on the experiment, a sample area could contain a variety of results.

Given:

The sample space for rolling two 6-sided dice, there are 36 possible outcomes

(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)

(2,1),(2,2),(2,3),(2,4),(2,5),(2,6)

(3,1),(3,2),(3,3),(3,4),(3,5),(3,6)

(4,1),(4,2),(4,3),(4,4),(4,5),(4,6)

(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)

(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)

The possibility of getting sum of three is (1,2) and (2,1)

and, The possibility of getting sum of ten is (4,6), (5,5), and (6,4)

Thus, the expected winning on a role is

= (2/36) x 20 + (3/36) x 10

= $1.94

If the gambler paid $5 which means

= -$5 +$1.94

= -3.06

Hence, The gambler can expect to lose $3.06 per play on average.

Let's solve for w :

hence , value of w = 2 ~

Answer:

Choice d. w = 2 is correct

Step-by-step explanation:

[tex] \\ \frac{2w + 4}{2} = 6 - w[/tex]

[tex] \\ \mapsto2w + 4 = 2(6 - w)[/tex]

[tex] \\ \mapsto2w + 4 = 12 - 2w[/tex]

Answer:

A probability must be between zero and one.

Step-by-step explanation:

Probability is the chance of something occuring. 120% is not realistic in real world examples, because the probability standard ranges from "definitely will not happen" to "definitely will happen", meaning a 0% chance of it occurring to 100% chance of it occurring. The only time 100.0%+ will be applicable are typically in simulations, which allows for such to counterbalance any negatives percentages that is allocated to the target. However, in the real world, it will never go over 100%.

Answer:

Step-by-step explanation:

Hope this helps :)

Answer:

First one is False, second one is true.

Step-by-step explanation:

For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.

For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.
