For problems 8-10, find the measures of the unknown third angles.​

Answer:

0.75 ;

150

Step-by-step explanation:

Probability of rolling two even numbers :

{1, 2, 3, 4, 5, 6}

P(even) = 3 / 6 = 1/2

From a roll of 2 dice :

P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25

P(not even) = 1 - 1/4 = 3/4

X : ____ 6 _______ - 1

P(x) ____ 0.25 ____ 0.75

Expected value :

Σx*p(x) = (6*0.25) + (-1 * 0.75)

= 1.50 - 0.75

= 0.75

If 200 games are played :, n = 200

Expected value * n

0.75 * 200

= 150

Step-by-step explanation:

Adding 2 negative numbers is like subtracting. You do -6 - 7. Negative 7 is literally - 7. -6 -7 = -13

Answer:

-6 + (-7) = -13

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

The slope would be 0 because the y value is not increasing.

Answer:

the slope is 0

Step-by-step explanation:

Answer:

y=-3x+10

Step-by-step explanation:

Slope formula y2-y1/x2-x1

7-1/1-3

simplify

6/-2

simplify

-3

now plug -3 into y=mx+b

y=-3(x)+b

choose any point and plug it into the equation, I am using (3,1)

1=-3(3)+b

simplify

1=-9+b

add 9 to both sides

b=10

plug into slope-intercept form

y=-3x+10

Answer:

5.83095 or √34

Step-by-step explanation:

Find the difference between coordinates:

(x2-x1) = (-1 - -4) = 3

(y2-y1) = (-10 - -5) = -5

Square the results and sum them up:

(3)2 + (-5)2 = 9 + 25 = 34

Now Find the square root and that's your result:

Exact solution: √34 = √34

Approximate solution: 5.831

Answer:

x = 15.6

Step-by-step explanation:

use the pythagorean theorem:

a² + b² = c²

a = 9

b = x

c = 18

(9)² + x² = (18)²

81 + x² = 324                    subtract 81 from both sides

x² = 243                            take the square root of both sides

x = √243

x = 15.6

Answer:

y=3

(bc it is the same length as its perpendicular counterpart.

x= 9 (same with Z)

(From pythagorean theorem)

6^2+3^2= (root of) 45

and square root 45

and it is the same as its counterpart (which is z)

Step-by-step explanation:

as I explained on the answer(it doesnt let this part be unwritten)

Answer:

slope is 3/2

Step-by-step explanation:

To solve for slope: y2-y1/x2-x1.

2 points can be (3,1) and (5,4)

4-1/5-3 ---> 3/2.

Also the slope is going up by 3 units and across by 2 units

Answer: 34.18%  

Step-by-step explanation:

Given: On Saturday, Number of cupcakes sold = [tex]26\dfrac12[/tex] dozens

= [tex]\dfrac{53}{2}[/tex] dozens

[tex]=\dfrac{53}{2}\times12[/tex]    [  1 dozen = 12 items]

[tex]=53\times6\\\\=318[/tex]

On Friday, Number of cupcakes sold = [tex]19\dfrac34[/tex] dozens

= [tex]\dfrac{79}{4}[/tex] dozens

[tex]=\dfrac{79}{4}\times12[/tex]    [  1 dozen = 12 items]

[tex]=79\times3\\\\=237[/tex]

Increase in cupcakes = 318-237=81

Percent increase in cupcakes sales from Friday to Saturday = [tex]\dfrac{81}{237}\times100[/tex]

= 34.18%   (approx)

The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%  

Answer: 8

Step-by-step explanation:

For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.

10 subtracted by 2 is equal to the number 8.

The answer to our question is 8.
