If a player rolls 2 dice and gets a sum of 2 or 12, he wins $30. If the person gets a 7, he wins $10. Otherwise he wins nothing.

makkiz [27]

If they were to win $30 they would expect to get $27 in profit.

If they were to win $10 they would expect $7.

If they were to win $0 they would expect $-3 in profit, so technically if they win nothing they lose money.

Hope I could help! :D

If ABCD (shown below) is a parallelogram, what is the measure of angle ABC?

yarga [219]

Answer:

Step-by-step explanation:

From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.

9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.

25x + 5 = 180

25x = 180 - 5

25x = 175

$\frac{25x}{25} = \frac{175}{25}$

x = 7

now let's substitute in the angle < DCB( 16x):-16 × 7= 112
To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180

<ABC + 112 = 180

< ABC = 180 - 112

< ABC = 68

IT WAS SO DIFFICULT TO EXPLAIN WITH PHONE BUT I TRIED MY BEST

hope it helps

for any question comment me ❤❤

Find a pair of integers whose product is-36 and whose diffence is 15.

Natasha_Volkova [10]

Answer: $(12,-3)\ \text{or}\ (3,-12)$

Step-by-step explanation:

Given

The product of integers is -36

The difference of integers is 15

Suppose the integers are x and y

$\Rightarrow x-y=15\\\Rightarrow x=15+y\\\Rightarrow xy=-36$

Put the value of $x$ in the product

$\Rightarrow (15+y)y=-36\\\Rightarrow 15y+y^2+36=0\\\Rightarrow y^2+12y+3y+36=0\\\Rightarrow y(y+12)+3(y+12)=0\\\Rightarrow (y+12)(y+3)=0\\\Rightarrow y=-3\ \text{or}\ -12$

$\therefore x=12\ \text{or}\ 3$

Pairs of integers are $(12,-3)\ \text{or}\ (3,-12)$
