Answer:
2.601
Step-by-step explanation:
Given that:
White balls, W = 5
Black balls, B = 3
Orange balls, O = 2
Total = (5 + 3 + 2) = 10
Winning = $2 for each black ball chosen
Winning = - $1 for each white ball
Sample space for making 2 selections ; order does not matter :
{WW, WO, WB, OO, OB, BB}
WW __WO __WB __OO ___OB __BB
-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4
WW = 5C2 / 10C2 = 0.2222
WO = (5C1 * 2C1) / 10C2) = 0.222
WB = (5C1 * 3C1) / 10C2) = 0.3333
OO = (2C2) / (10C2) = 0.0222
OB = ((2C1) * (3C1)) / 10C2 = 0.1333
BB = 3C2 / 10C2 = 0.0667
Expected winning = Σx * p(x)
(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)
= 2.601

Find c. Round to the nearest tenth. Laws of sines
9514 1404 393
Answer:
c ≈ 56.3 cm
Step-by-step explanation:
I find it convenient to turn the given equations upside down. Then you just need to multiply by sin(C) to get the solution.
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (27 cm)sin(102°)/sin(28°)
c ≈ (27 cm)(0.978/0.469)
c ≈ 56.3 cm

What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
WE are given that angle CAD = 36 degree
So, we know that parallelogram has parallel opposite sides.
Thus according to alternate interior angle we can say that;
angle CAD = angle m<1 = 36
therefore, the measure of angle m<1= 36°

Sin Z=30/50 or 3/5
Step-by-step explanation:
To figure out Sin Z, you need the formula which is Sin=o/h
O=opposite
H=Hypotenuse
To find opposite, you locate the angle(angle Z) and you draw an arrow that is opposite of the angle. To find hypotenuse, you pinpoint the right angle and you find the degree that it is opposite of.
O=30
H=50
Finally, you simplify 30/50 to get 3/5ths. Hope this helps you out!

Step-by-step explanation:
x/5 + 20 = 20.1
5x + 20 = 20.1
Answer:
No solution
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
a) The value of x in equation (a) is x = 0.5.
b) The value of x in equation (b) is x = 0.02.
Let's solve the equations for the value of x:
a. X/5 + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
X/5 = 20.1 - 20
Step 2: Simplify the right side:
X/5 = 0.1
Step 3: To solve for x, multiply both sides by 5:
X = 0.1 * 5
X = 0.5
So, the value of x in equation (a) is x = 0.5.
b. 5x + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
5x = 20.1 - 20
Step 2: Simplify the right side:
5x = 0.1
Step 3: To solve for x, divide both sides by 5:
x = 0.1 / 5
x = 0.02
So, the value of x in equation (b) is x = 0.02.

What percent is 45 of 72?
Answer:
32.4
32.4 is 45% of 72
Step-by-step explanation:
Solution:
What is 45% of 72?
Y is 45% of 72
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 45% * 72
Converting percent to decimal:
p = 45%/100 = 0.45
Y = 0.45 * 72
Y = 32.4

50 POINTS PLEASE HELP! Write g (x)=2f (x) as a piecewise function f (x) is defined as follows:
SEE PICTURE
Step-by-step explanation:
Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).
For x + 6 if x < 2,
It becomes 2(x + 6) if x < 2.
We have 2x + 12 if x < 2.
For x² + 4x - 15 if 2 <= x <= 5,
It becomes 2(x² + 4x - 15) if 2 <= x <= 5.
We have 2x² + 8x - 30 if 2 <= x <= 5.
For 5 - x if 5 < x,
It becomes 2(5 - x) if 5 < x.
We have 10 - 2x is 5 < x.
The answer is the 1st option.
