The amount of money which is expected to lose if the game of spinner is played 1000 times is $111.
What is probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
You spin the spinner two times.
If you get blue both times, you win $15. If you don't, you lose $2.Let suppose there are total 12 outcomes on a spinner which has 12 blocks. In this block, 4 is blue. The probability of getting blue twice in this spinner and earning $15 is,
[tex]P=\dfrac{4}{12}\times\dfrac{4}{12}\\P=\dfrac{1}{9}[/tex]
The probability of not getting two blue in two spun and losing $2 is,
[tex]P^{-1}=1-\dfrac{1}{9}\\P^{-1}=\dfrac{8}{9}[/tex]
The money to expect to win or lose if you play this is,
[tex]E(X)=15\times\dfrac{1}{9}-2\times\dfrac{8}{9}\\E(X)=-0.111[/tex]
For 1000 games,
[tex]E(X)=-0.111\times1000\\E(X)=-111[/tex]
Thus, the amount of money which is expected to lose if the game of spinner is played 1000 times is $111.

Find the measure of the arc or angle indicated.
A. 118°
B. 62°
C. 124°
Answer:
You can measure an arc in degrees. Just like you measure an angle in degrees. And you assign the exact. Same measure in degrees to an arc. As the measure of the central angle that creates that arc. So I believe your answer would be A: 118 :).

Alicia cashed half of her paycheck and set aside the other half to take her friends out to dinner. She spent 42.15 on dinner and brought home more than 20.00. Write an inequality to represent the situation, using x to represent the amount of Alicia’s paycheck.
Answer: = x > $124.3
Step-by-step explanation:
Alicia's Paycheck = x
Took half money for dinner x/2
She spent $42.15 on dinner and she brought home more than $20.00
.x/2 - $42.15 > $20.00
=> x/2 > $62.15
=> x > $124.3

Answer:
Pasos para resolver una ecuación lineal
3x−2/4−2x+5/3=1−x/6
Multiplique ambos lados de la ecuación por 12, el mínimo común denominador de 4,3,6.
36x−3×2−24x+20=12−2x
Multiplica −3 y 2 para obtener −6.
36x−6−24x+20=12−2x
Combina 36x y −24x para obtener 12x.
12x−6+20=12−2x
Suma −6 y 20 para obtener 14.
12x+14=12−2x
Agrega 2x a ambos lados.
12x+14+2x=12
Combina 12x y 2x para obtener 14x.
14x+14=12
Resta 14 en los dos lados.

Work out the value of s
S= ut + ½ at^2
u= 10 a=-2 t=1/2
Work out the value of s.
Answer:
s = [tex]\frac{19}{4}[/tex]
Step-by-step explanation:
substitute the given values into the equation
s = (10 × [tex]\frac{1}{2}[/tex] ) + ( [tex]\frac{1}{2}[/tex] × - 2 × ([tex]\frac{1}{2}[/tex] )² )
= 5 + (- 1 × [tex]\frac{1}{4}[/tex] )
= 5 - [tex]\frac{1}{4}[/tex]
= 4 [tex]\frac{3}{4}[/tex]
= [tex]\frac{19}{4}[/tex]
in the diagram below. C is an equal distance to A and B.
Answer:
C(50;-20)
Step-by-step explanation:
The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)

Answer:
A: (x, y) → (x + 1, y + 2); (-2, 6)
Step-by-step explanation:
The A vertex started at (-3, 4), [ x = (-3) , y = 4 ]The triangle translates two units up meaning y+2The trinalge also translates one unit to the right meaning x+1, but if it was to the left it would be minus, since we are basically graphing x and y.Equation needs to have x + 1 and y + 2 which is only found in the answer A equation. (x + 1, y + 2)Verify X and Y final vertex. x originally equalled (-3), if we take that integer and +1 we get (-2). and the same for y, y originally equalled 4, if we take that number and +2 we get 6.which makes (-2, 6)Which perfectly equals our selected equation. The answer is A.
Hope this helped :)
ABCD is a parallelogram
Answer:
a) 2a
b) -a + b
c) -b -a
Step-by-step explanation:
a) From C, you just go down with a twice.
b) From A, you go up the a hence -a, then you go down b so -a + b.
c) From B, you go down b to O then you go up a to C.
What are the excluded values? b = 0 and -10 b = 2 and 5 b = 3 and 7 none of the above
b= 2 and 5
